AP-Racing Radi-CAL By Stillen BBK Now Available!

For many years, AP Racing has provided brake systems for a majority of world class motorsports applications, and with their success on the track they have decided to bring that technology towards the street cars.  AP Racing and Stillen have come together to build one of the newest and most effective big brake kits in the industry to date.  Their engineers have built a big brake kit that offers a 20 percent lighter and stronger caliper than any other big brake kit available with a pressure forged aluminum process and internal seals rated for supercars like the Bugatti veryon.

Why Radi_CAL1

The engineering behind the rotor structure and use of the “J-Hook” has allowed for reduction in un-sprung mass and also aid in thermal efficiency.  The “J-Hook” design allows the rotor to vent and also help in initial bite between the brake pad and the rotor as the leading edge of the J-hook will allow the driver to get a better feedback once the brakes are applied.  The two piece floating rotor design allows the rotor to expand and contract under thermal stress and allow the rotor to remain centered, thus reducing brake pad knock back.

For the weekend racers, AP engineers have thought about the time between sessions that people have while at the track and the additional time it takes to replace brake pads on other big brake kits.  AP Racing has incorporated a removable “H-support” on top of the caliper to make changing brake pads a breeze as seen below.

Why-Radi-CAL3

These brake kits are now available for the following manufacturers: Audi, BMW, Cadillac, Chevrolet, Chrysler, Dodge, Ford, Infiniti, Jeep, and Nissan.  Contact us today for pricing on this big brake kit for your vehicle and we promise you that you will not be dissappointed!

SOHO Motorsports Single Turbo Kit Comparison Results

Over the last few months we have received a lot of interest from customers in that they were curious to see what the differences were between the Garret GTX3582R turbo, which is currently supplied in our turbo kit, and the Garret GT3582R turbo.  At SOHO Motorsports we are always researching different products and combinations of products to inform our customers, and this past weekend we were able to perform a test between the two different turbochargers on our turbo kit.  In this test we tried to keep all of the variables the same to provide an accurate comparison and the only adjustment that we had to make was the air fuel ratios so that they were the same for both of the runs with each turbo setup.  In the graph below you can see that the red line shows the run with the GT3582R turbo and the blue line shows the run with the GTX3582R turbo.

Garret GT3582R vs Garret GTX3582R

Garret GT3582R vs Garret GTX3582R

In the graph above, between 3000 to 3500 rpm, there is a 13.62 percent difference in horsepower and torque that was calculated.  Due to the greater efficiency of the GTX3582R turbo, the increase in power can be seen as soon as boost starts to come in and eventually starts to taper off throughout the power band.  The overall increase in power throughout the power band was 2.48 percent until the maximum rpm was reached between the two turbo combinations.  With the current layout of the piping of our turbo kit, both turbo combinations were able to reach maximum boost (5 psi) at the same time, which was around 3350 rpms.  A comparison between the two turbo combinations and a non turbo stock VQ35DE nonrev-up can be seen in the graph below, where the green line represent a stock VQ35DE.

Garret GT3582R vs GTX3582R vs Stock VQ35DE

Garret GT3582R vs GTX3582R vs Stock VQ35DE

The graph above will allow you to understand the gains that can be seen when a VQ35DE and forced induction combine.  When comparing the turbo combination with the GT3582R and a naturally aspirated VQ35DE, there is a 32.31% increase in horsepower and a 39.38% increase in torque that occurs.  The GTX3582R turbo combination creates a 34.06% increase in horsepower and a 40.90% increase in torque at a boost pressure of only 5 psi!  As boost pressures increase, the difference in power between the two turbo setups will be exponential as the GTX will be in a higher efficiency range in the compressor map, which will allow for more power to be made at the same boost level.  In conclusion, customers that are planning to build their motor and run more than 6 to 8 psi of boost, we would recommend selecting the GTX3582R turbo, while the customers that are planning on using the turbo kit on a stock VQ35DE at a low boost pressure to select the GT3582R turbo.  The benefit for the customer who will be using the stock motor and the GT3582R turbo is that they will be able to save $500 off of the total price of either SOHO Motorsports turbo kit package!  Please visit our online store for the updated pricing on the single turbo kit with the GT3582R turbo and visit the SOHO Motorsports turbo section for more information about our single turbo kit or contact us today if you have any questions.

#44 SOHO G35 Finishes the 2013 Season Strong!

11031080386_9da2534981_h

The end of every racing season is usually the busiest and this year busy didn’t even begin to describe how we finished the year. After a long racing season of ups and downs, battling new car blues, on the newly rebuilt #44 SOHO Motorsports Infiniti G35 we were eager to finish out the 2013 season strong with quite possibly the two most important races the #44 car has seen yet. Our November schedule had us going from our shop in Charlotte, NC nearly 5,000+ miles round-trip to the 10th Annual Super Lap Battle / Global Time Attack Finale at Buttonwillow Raceway in California. And then less than 10 days later we had to go from CA to NC and then down to Florida for the North American Road Racing Association USTT Season Finale at Sebring International Raceway only to leave there and go to Indianapolis for the Performance Racing Industry show a week after that. November was a crazy month for us and we are just now getting caught up on the website articles and updates including some quick summaries of the final races of 2013. For more in-depth details of each race please visit our driver’s site at www.kparlettracing.com

BUTTONWILLOW_GTASLB13_zeta 147

The 10th Annual Super Lap Battle / Global Time Attack Finale at Buttonwillow Raceway is easily the biggest Time Attack event on this side of the globe. All of the fastest TA cars and teams on this hemisphere make the annual mid November trek to sunny California to push their vehicles to the limit around the dustbowl that is Buttonwillow Raceway. With the event being at the same track for the last ten years it has become a staple in the North American TA scene and is where the fastest cars in the country duke it out to crown a champion each year in multiple classes. Having only had the #44 G35 built for a few years now this was our first time at the event so we were expecting to do okay but with the heavy hitters out there and no experience at the track we had reasonable expectations, but were hoping for the best. With a nearly non stop 36 hour tow from NC to CA out of the way our driver Kevin Parlett arrived at Buttonwillow and put on his helmet and prepared for battle around the 3.1 mile track with 12 turns covered with tons of dirt and dust.

 

Our first Super Lap Battle didn’t quite turn out the way we wanted it to but the adventure as a whole was worth the raceday headache. In the first session while learning the track and chasing the setup we had some contact with another car and had some slight body damage to the right rear fender and aero package. After taking a hammer to the damage and getting it back into working shape Kevin took a deep breathe and went back out in the second session to work off the nerves and learn the track some more in preparation for the 3rd session which most were expecting to be the fastest. Unfortunately SLB is only a one day event which for us was a pain because it is a track that is nearly impossible to learn how to drive or setup a car properly in just one day. Plus with us being from the East coast it was much more technical and tighter than anything we were used to along with the added joy of dirt and dust on nearly the entire track surface, so needless to say we were behind the 8 ball if not completely off the pool table before we even started hot lapping. Either way we made a few adjustments after the 2nd session and went out in the 3rd and 4th session gaining a ton of time in each outing but the one day wasn’t enough to get it done. Frustrated, tired and worn out we finished the raceday in 7th place in Limited RWD. No where near the podium we had hoped for and just barely missing out on the 2013 Global Time Attack Limited Class championship by a few measly points. The result wasn’t what we wanted but we knew our first time to the big game was going to involve a steep learning curve and hopefully with what we learned this time out we will be much faster next year for the 2014 SLB. Either way we didn’t have much time to dwell on the poor finish as the next morning we had to leave California and trek across the country for our last race of the season just 9 days later in Sebring, FL.

NARRA Sebring Nov.22-24, 2013 ColourTechSouth DL - 5 047

With an uneventful but unbelievably long drive back to the shop in NC we quickly unloaded the car and got it all cleaned up from the tons of dirt and dust from Buttonwillow and our cross-country trip on an open trailer. Then we addressed some of the damage, changed the tune to comply with the NARRA power to weight rules and changed the setup to comply with the completely different and very bumpy Sebring International Raceway. Going from Buttonwillow, CA to Sebring, FL in one week wasn’t just insane for having to tow that many miles but the tracks couldn’t be more opposite from each other. Buttonwillow was 3 miles of tight technical dust covered asphalt that barely allowed us in 5th gear and Sebring was a ginormous 3.75 track with multiple straightaways that allowed us to top out 5th gear not once per lap but multiple times each lap and may have been the fastest track we have ever been to. Needless to say our driver was excited to stretch the legs of the #44 G35 one last time to finish out the season and we knew that with such a large track it would play into the hand of the #44 car and hopefully put us on the podium.

NARRA Sebring Nov.22-24, 2013 ColourTechSouth DL - 10 007

The NARRA USTT finale was the final points race of the season and we were mathematically in the running for the 2013 NARRA USTT North Cup Championship in TT1. All we needed to do was finish in the top 3 and beat two fellow racers who were ahead of us in points. It was a tall order but certainly possible and after our dismal finish in California we were all ready to finish the season on a high note and hopefully walk away with a championship as well. After driving across the country we experienced every weather from 30mph winds to snow to sweltering heat and everything else, so when we got to Florida and felt the sunny 85 degree weather we were very excited to be wearing shorts a few weeks from Christmas and anxious to race in such perfect late season weather. Bright and early Saturday morning we got the car unloaded, passed tech, attended the drivers meeting did some reconnoissance laps and before we knew it we were in the final first session of the year and excited to see what the #44 car could do around the infamous Sebring.

Once again we were at a track we had never been to before, so the first session was used to learn the line and sort out the car setup all while still going as fast as possible knowing it was a one day double points event with only 5 sessions so each session was crucial. Luckily for us after the first session we were sitting 2nd in TT1 and one of the racers we needed to beat for points did not show up, so our chances were looking pretty good early in the day. Going into the second session we made some tire pressure and sway bar adjustments and went out and put down what would end up being our fastest lap of the day for us. Unfortunately on that same fast lap on one of the straights our 5th gear went out on us and refused to let us engage without some serious abuse. This transmission issue would plague us for the rest of the day along with the very high FL temperatures making the track less cooperative as the sun baked the track bringing out all of the grease and overheating our Hankook Ventus TD’s. With the NARRA USTT rules every class is allowed to run racing slicks but with our car having just come from SLB/GTA we were still on our 80 tread wear Ventus TD’s designated by their rules so we were at a slight disadvantage but we were still holding our own firmly on the podium. Unfortunately in the last session of the day we were bumped from 2nd to 3rd but we were still on the podium and with that podium finish we had clinched the 2013 NARRA USTT North Cup Championship for TT1! It was a hell of a way to finish the 2013 season and we couldn’t have been happier to have won our first TT championship in the #44 SOHO Motorsports Infiniti G35 and gave us a ton of momentum going into the upcoming 2014 season. Until then enjoy the photos and videos in this post and be sure to check back for more updates in the future along with more in-depth info about these races at www.kparlettracing.com

2nd Annual Charlotte Showdown | East vs West


The 2nd Annual Charlotte Showdown | East vs West – Dyno Duel and Car Show presented by SOHO Motorsports and CES Motorsport last weekend was a huge success! This year we moved the event date back to mid October instead of early summer like the previous year in order to get some cooler weather and hopefully some high numbers on the dyno board. Luckily for us and the tons of people who showed up for the event the weather was perfect for great horsepower with sunny skies and temps in the high sixties. This year we were expecting a large turnout for the dyno competition with much more impressive vehicles to lay down some impressive numbers, but even we were blown away by the nearly 50 cars that were strapped down and the the thousands and thousand of horsepower / torque we saw throughout the day.

Not only that but our inaugural car show was a hit with some impressive cars of its own. The 2013 Charlotte Showdown truly was a showcase for the best vehicles in the area on the dyno and in the show with nearly every make and model represented from Corvette’s to M6′s to GTR’s to Lambo’s to Supra’s and Mustang’s and even our Time Attack Infiniti G35. The diversity of the different vehicles, which was in the hundreds throughout the day, was very impressive and any auto enthusiast would have certainly found something to drool over.

As usual with the dyno and car show we had our raffle that left many people smiling at the end of the day thanks to our associate sponsors for the event including TurboSmart USA, Assaultech PerformanceMotivated EyewearDriven Steering Wheels, Sneed Speedshop, Computech and of course ourselves and CES put up some good prizes to make it even better!  Along with that the CES shop was open with display vehicles from CES Motorsport and SOHO Motorsports showcasing some of the things we have been working on. Combine all of that with Monster Energy giving out their delicious drinks, DJ Thanasti playing great music all day, food on site and the absolute best vehicles this area has to offer and you can see why this year’s Charlotte Showdown was quite possibly one of the best events of the year!

Now with the general summation done its time to get down to the good stuff… who won!? East (Asian Vehicles) or West (Euro / American Vehicles)? Before I get to the Dyno Duel I have to thank those who were a part of our first car show from those who hard parked all day and gave us some beautiful scenery to look at. And of course we have to give a shout out to this year’s winners! Best in Show went to Jonathan O’Brien in his Lamborghini LP-560, Best of the West went to Dung Nguyen in his BMW 328i and Best of the East went to Corey Sanders’ Nissan 350Z!

886713_10151669406555824_1142966897_o

There were tons of impressive vehicles in the parking lot but a whole different event was going on in the shop that required more brawn than beauty. At the first annual event in 2012 the East won by a pretty good margin leaving the West to think about the bitter loss for over a year. This gave them plenty of time to recruit their friends and in the hopes of taking it to the East at this years event. And anyone who attended knows they did not disappoint!

1397201_10151672180150824_817168962_o

Starting at 10 am and averaging a car nearly every 10 minutes the event crew ended up having 49 different vehicles compete in the Dyno Duel, shattering the high number of 34 we had the year before. It was astonishing how many cars wanted to compete but even more so the quality of cars that this years event had brought out. If you’re not familiar with the format of our unique dyno competition we take the top 5 highest combined hp and tq vehicles from each side and cumulate the totals together in a team style dyno competition pitting East (Asian made vehicles) vs West (American/European made vehicles). This year’s top 5 from each side was unbelievably competitive with nearly every car having a combined 1,000 hp/tq, it was quite a show to see.

922418_10151808697853863_2005336307_o

The East got out to an early lead and maintained it by a slim margin for most of the day getting there hopes up for a 2nd straight win. Until late in the afternoon on literally the last car of the entire event the West pulled their wildcard via Jimmy Bacogeorge’s 98′ BMW E36 and saved their best for last. With the competition on the line Jimmy turned up the boost for the first time on his new Turbo By Garrett GTX40 setup and laid down a very, very impressive pull of 682hp / 599tq!!! Good enough to not only push the West ahead of the East for the overall victory but also crown Jimmy and his BMW as the King of the Dyno! This year’s team totals were astronomically high with the winning West tally at 5,500 hp/tq to the equally impressive but losing East total of 5,293 hp/tq!!!

CSD-1

The 2nd Annual Charlotte Showdown | East vs West seemed to be well received by everyone in attendance. We know we had a blast and sure hope everyone who came out did as well! We look forward to hosting this event again next year and making it bigger and bigger every year, so do us a favor and share this article, tell your friends and be on the lookout for the next event! Also be sure to check back to the post often as we will be uploading our video in the coming weeks from the event.
