Want 500 rwhp out of your naturally aspirated, stock bottom end LS2? Let us show you how! Our own 2005 GTO put down 503 rwhp with a set of Advanced Induction ported 243 cylinder heads, Flowtech Induction cam, and a v8muscle.net custom tune! Furthermore, this was through the stock 4L65E automatic transmission and a set of 3.91 rear gears in the stock IRS! This is a daily driven car with excellent street manners. Best ET to date is 7.14 @ 99 MPH in the eighth mile. Dyno sheet and detailed modification info can be found here...
Rich's 2008 Z06 comes in for a tune and leaves the shop with 504 rwhp!
How about a stock 2008 Chevy Corvette Z06 with only a set of LG Super Pro long tube headers, Vararam CAI, and a v8muscle.net custom tune? Rich's internally stock Z06 made an astonishing 504 rwhp and 493 rwtq! What's even more impressive is that the torque curve stays over 400 ft-lbs from under 3000 rpm's all the way to 6500 rpm's. Check out the dyno sheet here...
How about a 434 rwhp 4 door sedan?
The mod bug strikes and Dave's stryker blue G8 GT gets a non-DoD cam, Yank SS3200 converter, Kook's LT headers, Vararam OTR CAI, and a Magnaflow catback exhaust. And with a v8muscle.net custom tune, it put down 434 rwhp and 400 rwtq on the dyno! Check out the graph, as well as pics and videos here...
Bill brings his Z06 up from Atlanta for a custom tune
Bill's 2006 Z06 was plagued with some driveability issues, so he called on us to remedy the situation. We spent the necessary time to correct all the part throttle tuning, then hit the dyno for some WOT adjustments. In addition to driving much better, it also put down 516 rwhp and 477 ft-lbs of torque. Mods include a very mild cam and long tube headers. The dyno graph can be seen here...
Bryan's C5 proves itself a force to be reckoned with on the street and the track!
Bryan's '99 C5 made 426/408 on motor and 560/672 on a 150 shot after our custom tune! Mods include a G5X4 cam, LT headers, and a set of stock LS6 heads. Best ET on motor so far has been a 7.34 @ 98.2 MPH on a 1.73 60'. Nitrous passes coming soon! Check out the dyno graph here...
Gary's 99 C5 FRC "Nemesis" gets a full street and dyno tune!
If you've been to Greenville's Quaker Steak and Lube on a Sunday night, chances are you've seen this car! Gary's 99 C5 FRC "Nemesis" gets a full v8muscle.net street and dyno tune! This beast put down 615 rwhp and 637 ft-lbs of torque! Mods include heads, cam, nitrous, and the usual supporting bolt ons. We'll find out soon whether or not he has the most important mod--the "driver mod".
Russ's 2004 GTO makes some impressive numbers despite some issues...
Russ's 2004 GTO already had a history of hurting people's feelings by breaking the 400 rwhp mark with the stock LS1 cam and just a set of Advanced Induction ported stock heads (and supporting bolt ons)! Well now he decided to take it a step further and see what could be done with an LS6 cam--yes, the same cam that came stock in 2004-2005 CTS-V's and 2002-2004 Z06's. The result is stock driveability and street manners, while putting down numbers indicative of a more radical setup! Despite uncovering some lifter issues on the 92k mile LS1, it still managed to put down 430 rwhp and 405 rwtq after our custom tune! Check back for some updated numbers with a fresh set of lifters, but that begs the question--will he keep the same heads or upgrade to a set of Trick Flow pieces ported by AI? Stay tuned...
Not your ordinary '03 Silverado! Sean makes the trip from Charleston for a custom tune!
Sean gave us a call and needed some help with driveability issues with his '03 Chevy Silverado RCSB. This truck has a very nice setup, starting with an LQ9 6.0L engine. Other mods include a TSP 224R cam, headers, Yank 3200 torque converter, and a set of 4.10 gears. For appearance, the truck is rolling on a set of 20" SS wheels. Once we got the part throttle driveability issues worked out, we strapped it down on the dyno to see what it made. Check out the dyno graph here...
"Texas Toxin": Big numbers and light weight make for a great combination!
Tired of your big dollar power adder car not making any power? Does your new turbo setup make less power than your old naturally aspirated motor? Tired of having to pay $6 a gallon for race fuel? Consider methanol injection. Today's methanol kits have really revolutionized the ability to run big boost with cool intake temps, all on pump gas. Case in point is Everett's beautiful Factory Five Cobra which has a turbocharged 5.0 engine. It came to us with some serious issues with low boost, high intake temps, and mediocre power levels. The baseline dyno produced only 380 rwhp. Just how much were we able to gain on this radical beast? Click here to read the rest of the story...
Another AI heads & cam car putting down some strong numbers!
When we found out Greg was going to bring his 99 Z28 up from Charleston for us to tune, we couldn't wait to get it on the rollers and see what it put down! His 99 Z28 has a set of AI ported 241 heads, AI custom cam, and the usual supporting bolt ons such as long tube headers, air lid, etc. The results were strong, as expected with this setup. Check out the dyno video on the left. Hopefully Greg will keep us posted with drag strip results soon!
Brandon's 02 WS6 makes big gains with just a couple mods!
Talk about bang for the buck, Brandon's 02 Trans Am WS6 A4 gained 57 rwhp with just a set of LPP long tube headers and a v8muscle.net custom tune! But this is just the beginning, Brandon has some more mods slated for this car in the coming months. Be sure to check back and follow his progress here. The dyno graph can be seen here...
What do you get when you take a G8 GT with a couple bolt on mods and add a custom dyno tune?
Spencer brought his beautiful 09 G8 GT to us for a custom dyno tune and picked up 25 rwhp! Mods include a cold air intake and a set of long tube headers. Final numbers were 365 rwhp and 383 rwtq, pretty impressive for a 4 door! Check out the dyno graph here...
Never enough! Josh's 2002 Z06 gets a total makeover and knocks on 700's door!
When Josh's 2002 420+ rwhp cammed Z06 was no longer enough, he called on JR Racing to take care of his latest build. Modifications include a set of Patriot heads, FAST 90mm intake manifold, A&A blower cam, A&A Vortech T-trim kit with a 3.8 supercharger pulley, and methanol injection. As it turns out, this setup performed even better than we could have expected. And with a custom v8muscle.net tune, it has excellent street manners while putting down some astounding numbers on the dyno! Check out the video clip on the left to see this beast making a dyno pull...
Just how much is a v8muscle.net tune worth for your forced induction car?
Bryan's C5 had already put down some good numbers on the dyno last year with a cam & nitrous setup. But with all the competition stepping up their game lately, it was time to go the blower route. After adding a Procharger P-1SC, he brought it to the JR Racing dyno for a custom v8muscle.net tune. The baseline dyno pull looked promising at 600 rwhp, but we knew there was much more power to be had. Once again, v8muscle.net went to work. The results? The video speaks for itself, but lets just say we have a new member in the "700 RWHP club"! In addition to the newfound power by optimizing the tune for his setup, the car also drives better than it did with the old cammed setup!
The 2010 Corvette Grand Sport has arrived! And we show you how to make it even better...
Steve just got this beautiful new Grand Sport Corvette and wasted no time before the mod bug struck! So he called upon Mike at East Coast Performance-Corvettes to put together a supercharger package for him. The A&A Vortech kit puts out 8 psi of boost on the otherwise stock LS3 engine. JR Racing stepped up to the plate for the install, and the crew at v8muscle.net finished it off with a custom tune. The result was stock-like driveability while pumping out 566 horsepower at the rear wheels, through a 6 speed automatic! We think Steve got the best of both worlds with this setup!

G8 on steroids! Spencer's car goes under the knife...
When you've got a car such as the Pontiac G8 GT, it's hard to leave it alone for very long. Spencer's G8 had already visited JR Racing for a set of long tube headers, but it didn't take long for the mod bug to strike again. This time he chose to have a custom cam, FAST 102mm intake manifold, and a Precision converter installed. All of this equates to one potent Pontiac! The car is also outfitted with a new set of custom designed Asanti wheels with a FAT lip out back. Be sure to check back soon for some videos of this beast.

Not your ordinary Trans Am, v8muscle.net welcomes our newest member of the 700 HP Club!
David's navy blue metallic 2000 Trans Am Mecham clone had been begging for a spot in the "700 Club" for a while now. After taking care of some minor details, we're proud to say that this beast made over 700 rwhp on the dyno! Under the hood is a forged LS6 with untouched 317 heads, custom blower cam from TSP, stock throttle body/LS6 intake, and a Procharger D1SC blower. Special thanks for the build goes to Chris G and BJ (Upstate Motorsports), as well as Matt at JR Racing for advice and dyno time. We look forward to seeing some track times from the Mecham soon--that is, as long as the 10 bolt holds up! We've got a pretty good guess as to what David's next mod will be.
Heatco's GTM and v8muscle.net make an appearance at Michelin's "Corvette Driving Experience" at their Laurens Proving Ground test track!
Some of the v8muscle.net crew made representation at Michelin's "Corvette Day" at their test track in Laurens, SC this past Saturday. While progress is still underway on the Heatco GTM, we are proud to say it came out of the garage and made the 50 mile trek to the event! A special thanks goes out to Steve Hankinson and Alan Forsyth from Heatco for making the special trip from Cartersville, GA to be a part of this event. Also in attendance were a couple members of our "700 rwhp club"--thanks Bryan and Gary!
Festivities of the day included the chance to auto-cross C6 Corvettes fitted with OE "GY" tires, then switch to an identical C6 fitted with Michelin tires for comparison. Michelin also had crew and equipment on site to be able to swap out tires for anyone wanting to purchase a set of their tires. Attendees were also able to make several laps around the test track in their own Corvette. This was a fun-filled day and we hope they will offer the chance to do it again in the future!
