| Hey Bob,
I just want to say that you are probably one of the sharpest guys on this Forum, not knocking anyone else. It's just when it comes to Forced Induction and F-Bodies, you know your stuff. Anyway I just got the 3.00" pulley on and it is working great . I'm seeing a little more than a pound of boost increase. I't feels like I gained about another 30HP or so. Only one problem, I'm detecting some detonation right before redline ( popcorn ) . So I filled it up with VP Racing fuel 103 octane. No more detonation. But that's not the answer ( very expensive fix ). I wish you were local. Could use a good old fashion chassis dyno tune. You wouldn't be able to recommend a shop down my way, could you?
Well, anyway - thanks, Ron

This area of our site includes details about some of the cars we've worked on.
Our main goal is to show if claims about increased performance made by manufacturers, vendors, or just your buddy down the street are accurate. In the following pages we'll explain what modifications we made and what performance increase, or decrease we found by using our chassis dyno to test the results.
Our second goal is simply to let you enjoy reading about some of the work that we've done on customer cars and our own cars.
If you'd like to know if a particular performance mod meets its manufacturer's
claims, let us know about
it. While we don't have access to every car ever made, it may be that
we can find out if it's worth the money or not
Cody Chandler's 06 GTO with an ATI ProCharger F-1C So far, this stick car has been brutal on parts! We noticed the splines on the driver side 35 spline axle were twisting, so we swapped out the axles to 40 spline while we were swapping the diff out to a spool. While we were at it we took the rear back over to Moser and had them add back braces to it. |

1982 Ferrari 308 GTSi EPP Project Car This Ferrari 308 GTSi is a shop car of ours, it actually belongs to Mike Westrick, a very good friend of mine who fronted all the money required to get our business up and running. http://www.ecoprem.com/index.html Check out this link to a relatively new business venture that Mike has invested heavily in. It doesn't have anything to do with cars, but this is really cool! Years ago we were going to install two turbos on the engine. Somewhere along the way, both distributors and some of the fuel system came up missing for the engine, as it has been partially dissasembled for close to four years. Hmm, since we are known for the GM LS related engines, why not... Stay tuned! |
2008 Hummer H2 with Magnacharger TVS 2300 Update: Bingo! The Lingenfelter MAF made a huge difference! 672 rwhp and 752 ft lbs of torque! Rwhp with from 645 to 672 with just the addition of the larger maf. Kudos to Khalid (from the business over is Saudi) to suggest we try a larger maf! |
Paul Heintz '93 Camaro Z28 396 LT1 with ProCharger F-1A Paul's Camaro came back to us because the transmission was shifting correctly. Luckily we did not supply the transmission, but we removed it and sent it in to have it rebuilt. While we had the car we also cut out the front grille for added airflow, and it has made a huge difference! These cars were designed to have air channel up from underneath the car, to get into the radiator. When you install a large front mount intercooler in front of the radiator, the airflow that actually gets into the radiator is dramatically less. Now the intercooler itself will also be a lot cooler, so in the warmer months this car will make a lot more power, than if the intercooler was heat soaked. |
Bob Johnsons 05 CTS-V/LS2 402 w/ATI ProCharger F-1A Bob's V is featured in the August 2008 issue of GM High-Tech! Make it a point to pick up a copy if you don't subscribe! If you have never looked at a copy of GM High-Tech, you will find it to be the best magazine related to late model GM vehicles! Bob's V was a top 10 finalist out of 178 vehicles on the Jan 2010 issue of Popular Hot Rodding! Congratulations Bob! |
Steve Verplank's '86 RX7/LS1 w/ATI ProCharger Update: 10/31/09 Steve just ran a 9.72 at 144 mph in the 1/4 mile Wednesday night at Muncie Dragway in Indiana! Congratulations! |
John and Rhonda Little's 2010 Camaro SS John had us order and install a complete Kooks header/exhaust system, and dyno tune his 2010 automatic Camaro SS. This exhaust system was the easiest exhaust system we have ever installed, and it looks and sounds great! |
Bob Beam's 2006 Cobalt SS Update: This car is for sale for $10,500.00 I just bought a Diesel pick-up 4x4 for a daily driver and tow vehicle. Brent used our EFIlive software and picked up another 7 hp at the front tires, along with 7 ft lbs more torque! Not bad for doing nothing other than refining the factory tune! If you look at the minimum eng torque we really picked up a lot of power. It went from a minimum of 139 to 168! This will make more of a difference than anything, and we may very well have improved the fuel efficiency as well. I'll let you know what I find out on the gas mileage. |
Chevy Colorado with LS7 427 and ProCharger F-1A MBRP Inc Performance Exhaust is building a new Chevy Colorado as a show truck for GM. They sent us a new LS7 crate engine last year for us to rebuild to handle the power this truck will be generating. This truck will be arriving at our shop around June 1st for us to install the fuel system, completely wire the truck and get it up and running and tuned. We will have exactly one month to get everything we need to do done, as this truck has to get shipped to Canada to get painted. |
Mike Collins 2010 Camaro SS Mike Collins picked up his new 2010 Camaro SS, and is not wasting anytime on adding more power to it! |
S. K.'s 2008 Corvette C6 with ATI ProCharger D-1SC Check this dyno graph out! We pulled as much timing as we could out of the engine when we wre tuning it, and it is still making 671 rwhp! These LS3 cylinder heads flow like crazy, these numbers were unheard of from a Mustang Chassis dyno with stock heads on the earlier LS engines! I talked to Shawn about putting a larger blower pulley on the blower to slow it down to reduce the boost level, and Shawn decided to try short shifting the car instead. Even if Shawn shifts at 5000 rpm, this is going to be one fast Corvette! Update: 7/18/09 Shawn just drove across country with this Corvette, stopping by our shop on his way home on his three week journey. No problems at all! |
EPP's Jon Beam's 1995 Pontiac Formula with ATI ProCharger Stand by while we prep this car to run NMCA True Street this season. The Wolfe 6 point Roll Bar is installed, we're getting close! |
Scott Hewitt and his Camaro SS with an STS Turbo The rollcage is installed, and the new customer has decided to wait to get the larger injectors installed for the time being. He is going to get use to the car with the current power before going for more power. |
Jordan Quilico's 2008 Z06 with an ATI ProCharger F-1R at 954 rwhp! Video of this car on the dyno can be found at the bottom of the page. |
Chad Cunningham's '69 LS2 Z28 The 502 engine and tranny were sold on Ebay from this Z28. We now have an LS2 engine and transmission from an '05 GTO installed, and this original Z28 is now 350 pounds lighter than it was with the big block! |
Tom Snitzers 02 Z06 Warhawk 427 Track Car Update: New video of Tom's Corvette from it's inaugural first day at the track. This car was driven by one of the track pro's on it's first day out and ran a 1:02 on the North track and ran a 1:28 on the South track. This was done on R6 tires, it will be even faster when slicks are installed! |
Heath Buchs and his 05 GTO/ATI ProCharger D-1SC Heath brought his GTO back to us this year to have a methanol kit installed. We were able to pick up another 30 rwhp with the methanol kit. Heath has changed the looks of his GTO significantly by adding the Monero body items to his car. It looks awesome! |
GM High Tech Performance Blogs and videos about our Camaro Check out the blogs and videos on GM High Tech Performance's website about us. Thanks Scott Parker! The LSX Shootout is coming up, we encourage everyone to make a point to be there! |
Bob Beam's '99 Hugger Orange Z28 with an ATI ProCharger D-1SC Starting at day one back in 2002 when I bought the Z28 with 110,000 on it. |
Chris Avery and his 1998 Trans-Am with an OFI Turbo Kit 921 rwhp on a Mustang Chassis Dyno!!!!! |
Tom Snitzer's 04 C5 with ATI ProCharger F-1C 804 rwhp with 15.9 psi of boost and only 17 degrees of timing! |
Tom Snitzer's 04 C5 with ATI ProCharger D-1SC The initial build from day one is shown here. |
Randy Hargraves and his 851 rwhp '02 Z06 HP Turbo'd Twin Turbo Corvette We have a video of this Corvette in action at 180 mph! Check it out at the end of the text within. |
John Gonzales and his 2000 C5 with an ATI ProCharger D-1SC New Update: We installed the upgrades from ProCharger to turn John's ProCharger kit into the 8 rib stage 2 kit. |
Super Chevy Event at ORP with ATI ProCharger 2007 Super Chevy Show in Indianapolis at ORP. We had four of our customer's cars at the ATI ProCharger display area. |
Tim Farrell's '02 Firehawk with an LS2 402/706 rwhp/758ft lb APS Twin Turbo! 705 rwhp/758 ft lbs torque on 93 octane with no octane booster, with methanol injection on close to 11.0/1 compression ratio on an eighty degree day! This car is now ready for the movies! |
Anthony Cobergs 07 Corvette with APS twin turbochargers 537 rwhp and 547 ft lbs of torque, not bad for a hot and steamy day on a Mustang Chassis Dyno! The average amount of boost is 6.1 psi, with a max of 7.1 psi. |
Ryan Billenstein and his 06 GTO with an APS twin turbo system! This goat made a lot of rwhp for only 6.8 psi of boost! 541 rwhp and 549 ft lbs of torque will be putting the hurt on the stock clutch in no time at all!!! It would be interesting to see what this turbo kit would be capable of with an engine with forged internals and a fuel system to go along with it. |
Richie Sposato and his 04 CTS-V w/ATI ProCharger D-1SC 602 rwhp and 637 ft lbs of torque with 11 psi of boost, not bad considering the hot and muggy weather we are currently having, plus the fresh engine only has about 100 miles on it. This would be 640 to 650 rwhp on a DynoJet unloaded type of dyno. Our Mustang Chassis Dyno, using eddy current, is more accurate but it does give lower numbers. Add approx 20% to the 650 rwhp number and you would be close to what this V is making at the engine! |
Joshua Rife's 402 '98 T/A w/ ATI ProCharger D-1SC That Mickey Thompson ET Street tire is a monster 28 x 13.50 x 15! It has a true 11.0 tread width on the ground, and has a 28.0 tire diameter. This wheel-tire combination is approx 20 pounds lighter per each wheel and tire, than the ones they are replacing. |
Mark Barrett and his '05 Cadillac CTS-V with an ATI ProCharger D-1SC New Videos From The Dyno;
Dyno Video #1 |
Our 1994 1500 hp 1994 Corvette Pro Mod Ted came in 2nd at the 1st annual Lingenfelter quick eight race, running a 4.64 in the 1/8th mile. With a little more tuning this car can easily drop several more tenths. |
Mike Lothamer's 03 Mustang GT with ATI ProCharger Mike had a mild 5.0L stroker engine built for his car, and we upped the boost level. The bottom end is now forged, but the stock heads and cams were retained. This engine is now producing a lot more torque than what it did before. |
Eric Metke and his C6 Corvette with an ATI ProCharger P-1SC-1 Conclusion: We started out at 323 rwhp on this bone stock C6 Corvette, and we are now at a consistant 470 rwhp. What a gain! 20 more rwhp than what a new C6 Z06 just did on another Mustang Chassis Dyno identical to ours. If this C6 had headers and a free flowing exhaust system, this Corvette would most likely be over 500 rwhp! The nice thing is the gas mileage will still be really good, and this car can still be a daily driver! |
Bryce Curry and his '96 LT1 Trans-Am We more than likely found out why Bryce's car initially hydraulic'd his first engine, bending a rod which started his whole three year nightmare. We found the fuel pressure regulator had internally ruptured, passing gas through it! |
Mike McCullough and his 717 RWHP '01 Trans-Am w/ATI ProCharger 717 rwhp and 717 ft lbs of torque - On a Mustang Chassis Dyno to boot! This would be well over 800 hp at the engine! |
Larry Tallent's 1977 Corvette with ATI ProCharger As luck would have it, the block on Larry's Jasper engine cracked while we were just starting to dyno Larry's car! Once we got the engine apart, the general concensus was that the block had to be cracked or prone to failure from Jasper. Jasper replaced the shortblock for us without any problems, and they were very easy to deal with. At this point we decided to have our ace engine builder put a shortblock together for Larry's car, using premium parts. Larry has reported that this new engine is much smoother and feels much stronger than anything that has previously been residing in his Corvette. |
Jerry Lockman and his '96 LT4 with an ATI ProCharger After some computer glitches were dealt with, we finally got this awesome looking LT4 Corvette tuned in. We were surprised to see 413 hp at the rear wheel on our Mustang Chassis Dyno! This Corvette would be close to 450rwhp on a Dynojet type of dyno, making this engine putting out around 500hp! This car is going to fly! My brother's '95 Formula LT1 with an ATI ProCharger makes 350 rwhp on our http://www.exoticperformanceplus.com/projectCar.php?car=7 chassis dyno, and runs 11.50 in the 1/4 mile. This tells us that this Corvette is going to be a hand full... |
Mike Lindley's 3400 Turbo 03 Grand Am After much frustration in purchasing a turbo kit for Mike's Grand Am, we decided to create our own turbo kit for Mike's car. We have had many request for a Grand Am turbo kit, so maybe this will turn into a production kit. |
Mike Dodson's '04 GTO w/ATI ProCharger D-1SC Update! 450 rwhp on our Mustang Dyno with 8 pounds of boost! This is going to be one quick GTO! |
Adam Henderson's 01 Camaro SS with ATI ProCharger Well it's finally done! I personally delivered Adam's car to him right before the snowstorm hit... 607 rwhp at 8 pounds of boost and 553 ft lbs of torque! What is really incredible is that this was done with a very loose racing converter. We typically don't see good dyno numbers when a loose converter is used! |
Jon Schlemmer's Nissan 350Z with ATI ProCharger Jon brought his timeslips in from our most recent day at the track. Jon had mounted a small pair of slicks on the car, which helped a little in the traction department. Jon still had to walk the car out of the starting line, but it did hook up better. |
Jeff Kirk's '04 Jeep Rubicon Jeff wanted us to install a Kenne Bell supercharger, along with a new suspension package, on his new 04 Jeep. Now this sounded like a fun project!!! All that is left is to dyno the truck now that it is finished! |
Brent Rau and his 7.55 1/4 m '99 turbo Eclipse RWD 10/2/04 Brent Malone just called me from Muncie Dragway and said they had to pull the transmission back out twice, as they burnt up some clutch packs, but... the first time they made a full pass the car with a 7.55 at 185mph!!! And Brent had to backpeddle it!! |
9/11 Dyno Day Video This is a really cool video that was taken during our September 11th Dyno Day! |
Justin Roberts '00 Honda Civic DX w/ATI ProCharger Justin Roberts purchased an NOS kit for his Honda Civic from us, which is what started his road to horsepower heaven! Next came a Carbon Fiber APC hood, and an adjustable coilover front and rear suspension, then the ATI ProCharger C-2 Honda supercharger kit was the next item! |
Feb 28, 2004 Dyno Day and Burnout Contest Pic's We had a blast and you will see by the pictures that the cops did too. |
