I know that there are a couple of 3800 series II turbo powered cars, so when I read the article below I thought I would post it for all to see. Now this might be the ultimate V6 swap of all times. Enjoy!
Scott Cook lives in Westerville, Ohio and drives our new project car - a 1998 Grand Prix GTP. We started on it in January and it was unveiled three months later at IDD III. The first day at the track was a complete success. First pass of it's life was 12.044, and the fifth pass was 11.634 @ 119.97 mph (1.852 60'). This car also has the distinction of having been the first ever 3800-powered FWD vehicle to exceed a 120 MPH trap speed at INTENSE Drag Day III on April 12, 2003. These numbers were done with only baseline (15.0 psi) boost.
It's second day at the track produced runs of 11.664, 11.335, 11.209 and a scorching 11.176 @ 125.01 (1.762 60') on April 29, 2003 at the High Performance Pontiac Magazine Shootout, which will be written up in the issue hitting the stands in mid July. The second outing was when this car became the first 3800 FWD to ever surpass the 11.50 second and 125 MPH trap speed barriers. Major changes since the first outing included slightly more boost (16.5 psi), suspension tweaks, better burnouts and just learning to handle the car at the starting line.
More chassis work made this beast much easier to handle by it's third outing on June 28, 2003, and resulted in more consistent launches. Three passes were made at 16.5 psi of boost: 11.138 (1.736 60'), 11.168 (1.737 60') and 11.130 (1.737 60'). Then the boost was turned up to 18.0 psi, netting a 10.998 @ 128.32 mph (1.727 60'). And so the INTENSE Turbo Car became the first ever 3800-powered FWD vehicle to break the 11.00 second barrier.
By August 2003, a beefier cam and higher stall torque converter were installed allowing us to get the turbo spooled quicker and start chipping away the times near the beginning of the track. We made nine passes at the Pontiac Nationals including new bests of 10.674 @ 129.34 mph (1.672 60') and a 1.644 60' time on a subsequent run - both with 19.5 psi of boost.
This car recently became the first ever 3800-powered FWD vehicle to exceed a 130 MPH trap speed on November 22, 2003. Our Turbo Project car is currently the quickest 3800-powered FWD vehicle in the world!. Now that the car is fully debugged and tuned, we plan to continue turning up the boost, and run much deeper into the tens in the near future.
In December 2003, we put this car on the dyno for the first time ever and shattered the all time 3800 Series II dyno record with a 655 horsepower pull! Two weeks later we did it again with a 670 horsepower pull! Read about it here...
Much chassis work was done and a larger turbo was installed for the 2004 racing season debut. The first outing netted an amazing 10.381 @ 136.58 MPH (1.655 60'). The video can be seen here. The car was built (and is NHRA/IHRA legal) to run as fast as 9.00. Here's the basic list of modifications:'
Engine 85 mm. Escalade MAF sensor Precision Turbo PT70GTQ compressor Precision Turbo custom intercooler ZZP-modified LS1 throttle body Wilson Manifolds-modified L67 lower intake/plenum Weldon 2015 fuel pump PRJ custom fuel logs Siemens 60.0 pound/hour fuel injectors INTENSE™ Stage 3 cylinder heads INTENSE™ MLS .054" head gaskets INTENSE™ 8.0:1 race short block INTENSE™ SFI-approved damper INTENSE™ double roller timing chain setup INTENSE™ Stage 3 turbo cam CompCams 'OE R Series' lifters INTENSE™ lightweight pushrods INTENSE™ 1.60:1 full roller rocker arms B & R Racing custom headers with ceramic coating by Toefco (1 5/8" primaries, 2 1/8" secondaries, 2 3/4" y-pipe, 3" downpipe) Accel custom 9 mm. spark plug wires Autolite AR103 Race spark plugs @ .035" gap ZZP Oversized W-body radiator
Transaxle INTENSE™ transaxle with 3.29:1 final drive ratio INTENSE™ TCC-400 torque converter
that car is awesome, i had the vid of it on my computer where it did the 10.998 run. i never realized though that it was still a "real" car, i thought it was a stripped out drag only vehicle. one question, is that thing street legal?

Thats awesome. Now sombody needs to build a motor like that for a fiero . You guys should all check out fierox's car too, He is shooting for 10s when he gets his tranny back. http://www.fierx.com . Good luck to anyone attempting this... Turbo > SC

Nice setup but I was talking about the 3.8 turbo 650hp in a fiero. Thanks for posting the picture, never seen that setup with a inter-cooler in the trunk. Usually by the time I get to the show everything in the trunk is hot though, how do you get air to cool the inter-cooler?

pretty sure FieroX has a 3800 turbocharged sitting in his garage. Waiting for the tranny to come back. He's got a large turbo as well. (Garrett T66) and is shooting for those hp numbers... but will probably be faster than that GP. And his is driven on the street all the time.

Thats spddy's Turbocharged, Intercooled, and Supercharged 3800. It was making over 500 rear wheel hp on the dyno before it sprang a small oil leak at 4500RPMs and they shut it down.
You can see in this picture the scoop on the decklid, in front of the wing. Mounted to the underside of that scoop is a fan pulling 950cfm down through the intercooler and out the bottom of the trunk.

When my setup is all done, I should be making somewhere near 540 wheel hp. Or about 650 at the crank. Not sure what it will turn for 1/4 mile times. My setup is totally streetable, and when I drove to wheatstock, it pulled 31 mpg on the highway. Also, it doesnt leak oil.

by the way, there was an electric fan underneath the rear wing, in the center. he cut out some ports through the deck lid to suck in the air from outside to the intercooler...
can someone explain to me why you would supercharge and turbocharge an engine? I don't get it
Cause they want to switch over to Diesel fuel once it's got the rrrrr's up :-)
As a kid growing up in the 70's/80's I still remember Rick Dobbertin's (sic?) Twin turbo, Twin supercharged Pontiac J2000.... excess for the point of being excessive. He's the guy that later built the vehicle out of a stainless steel milk trailer to try and drive around the world.

look up some early 90's japanese min-cars... i know of one that had a 660cc motor w/ a turbo and supercharger and only made 63hp. it was like a mini super-turbo or someting like that. i have always wonderd how they work and if they were sequintial or not.

looked up this super-turbo car and this is what i found out. The article explains how it works.
Well, under the bonnet lives Nissan’s fabulous MA09ERT 930cc in-line four. It’s not a particularly sophisticated engine with just a 7.7:1 static compression ratio, SOHC and 8 valves, but its bolt-on forced induction hardware is nothing short of amazing. The March Super Turbo employs one of the few OE supercharger/turbocharger set-ups in the world.
And it works a treat.
At low-to-mid revs, the 930cc four is boosted by a positive displacement blower (see Supercharger Steal - Part One for details). At higher revs, however, a relatively large turbo kicks in to give great top-end performance. Note that the transitional stage is very smooth thanks to a relatively simple supercharger/turbo control system. At low rpm the turbo blows through the supercharger which is effectively ‘free-wheeling’. Then, at high rpm, the supercharger is disengaged by an electro-magnetic clutch and the turbo feeds the engine via a supercharger bypass passage. Airflow through this passage is controlled by a differential pressure valve which begins to open as the turbocharger nears operating speed.
Give it just a whiff of throttle at low rpm and you’ll see the supercharger deliver up to 7 psi of boost. This means wonderful part-throttle performance but, curiously, flooring the throttle at this stage doesn’t necessarily equate to greater acceleration. At more than 4500 rpm, however, the turbocharger steps in and boost pressure swells to 13 psi. That’s when it’s go-go-go!

I have a question, please how can the fiero doors open up above the roof level instead of like the normal opening. I see the blue car and try to think how can this happen. The hinges are not swivel or rotating. they open just like a door. I saw that one side is extented to push the door up but not this far and wouldn't it put a strain on the upper hingle. i am so confused
