  • i am putting a gen v in my 97 and ordered the blockoff egr plate and bolts is there any computer issue that needs to be dealt with?

  • @ddog0804 You will need to delete the DTC's in the PCM relating to the EGR system.

  • He comeing from the marines an all my family has agreed to pitch in .thank you

  • Trying to fix my brothre car before jan pls help with measures n brands name 1997 gtp 3.8 wanna make his car run fast we already know wer to get it paint n chrome need intercooler size pulleys size an other sugg

  • How much boost?

    

  • @ClutchGT Was about 21 PSI for dyno.

  • That car is sick. Do you ever plan on making a full 1/4 mile pass?

  • @canada4g63 Need to replace intercooler core as it sprung a leak dumping coolant into the intake manifold.

    Also need to get a cage installed before we'll take it to 1/4 mile track since we got booted from the 1/8 mile already for running too fast without one (they actually called us out with a warning before even running!)

  • OTHER MODS?

  • Nice :)

  • what size rims u have on there?

  • @darthnater22 They are some very heavy 18's

  • gm 3800 series. FTW!

  • We need an update please!

  • @txslow6 The new engine/trans went in June 2010. We had some issues with the axles, that we didn't get resolved until April 2011. Also there was an issue with tubular lower control arms causing a suspension "pop" that we resolved at that time. The car hasn't been driven much in the last year (under 1000 miles) We need to replace the intercooler core as it developed a leak in May. Have not dynoed or taken to a 1/4 mile track yet, and have only ran it with 21 PSI of boost.

  • This needs RWD, I have one too and im no where near done with it. I really want it RWD so im investing some research on how to do that, I'm thinking a Camaro rear suspension such as the 95-99 Monte carlos

  • @DJTDames Must easier and cost effective to drop it in a back of a Fiero not to mention much lighter vehicle. That may happen in the distant future.

  • 537hp!!!! a la madre, thats one fas GTP.

  • How did you get a Whipple on thus?Do they sell them?

  • It takes a lot of work. There is no complete kit to do this. A lot of custom work involved. The engine has since been completely redone (installed June 2010) with custom billet crank, billet connecting rods, forged JE pistons, aluminum heads, new intercooler, new 90mm throttle body, new 100mm MAF. The transmission was also completely rebuilt with many new custom parts, and new custom 300M axles with Porsche 930 CVs. New engine runs great so far but still some items that need to be addressed.

  • @TheMrhoneycutt Whipple does not sell a kit for the 3800. You can buy the blower and bypass from them. The intercooler/adaptor plate we are now using and snout is from Yella Terra in Australia. The throttle body adaptor now on the car is a custom one off investment cast piece that mates up to a Holley 90mm throttle body.

  • @PrjPerformance you have a 90 mm tb on this? thats huge did u have to do any extra modifications or did it just pretty much bolt up

  • @ThriftyCougar Yes, it is a 90mm Holley TB and a 100mm Texas Speed MAF. The inlet adapter to the Whipple is a one off investment casting.

  • the mod bug.. it never dies. i bought another grand prix just to mod it too.. its a disease.

  • @kyle1058 im the same... i sold my black gtp that i did a few mods too to my ex of all people... now im buying a white 03 gtp thursday

  • @joe0813 ive got a very highly modded GT with an m112 blower on it that i made adapter paltes for, and ihave another grand prix (a gtp), and my ex had a gt.... so yeah.

  • @kyle1058 yea, i got a regal (same power train) the mod bug cant be stoped

  • would have been hilarious if the car went flying off the dyno hehehe

  • Torque steer much?

  • Not really. the Quaife ATB Differential takes care of that. Also, it will be getting new chrome-moly tubular lower control arms this spring.

  • @biggredd911 haha, for real!!! i bet u could turn a 90 degree corner just by flooring it

  • @alexanderocks

    ~785WHP

  • What is the displacement on this motor?? I have a 3.8l mustang that puts down 360ish to the wheels. Procharged and small n/a cam with a .541 lift. get it to

    Only thing I dont like about these cars is fwd...how do you get it to hook at the track??

    Great sleeper though!!

  • It's a 3.8 with .010 over pistons. Factory stroke.

    Some good slicks and some suspension mods are the trick to launching. Unforturnately, first run with this setup, busted an axle. Prior to the Whipple, we were pulling 1.65 sixty foot times.

    We won't have axle problems with the new custom built 300M axles with Prosche 930 CV's along with a 300M output shaft.

  • fwd lock up better. all the weights on the wheels. cornering is better as well

  • @stickit2damanleosis i know that this is a sort of old post, but your wrong on the second half. cornering is not better, other wise i would imagine that formula1, touring cars, nascars, ferraris porsches, corvettes high end mercedes and bmw, would probably be producing front wheel drive vehicles rather than the rear wheel drive. and before you yack about awd, lambo, bentley and all those awd performance cars, send most of the power to the rear wheels. to the OP sound like a lot hard work like it

  • no your wrong. all those cars are rear wheel drive because you can cram way!!!!!! more engine into a rear wheel drive car. period

  • @stickit2damanleosis tires can only withstand so much force. asking the front wheels to lay down all that horse power AND hold grip for cornering is too much. it has nothing to do with how much engine you can cram into a space. 911 turbo, rear engine, rear drive. there isn't that much space for a big engine yet they stuck with the RWD, and for a reason. not to mention the effects of torque steer.

  • thats my point. bigger motor will fit in the engine bay with rwd. you just proved what ive been trying to say. and awd has performance loss once your moving. theyre only good for 0-whatever cause they move when you put your foot down. anywho my grand prix will out turn any other car ive run into so far

  • @stickit2damanleosis ariel atom, lotus elise, caterham.... just saying.... i would suggest looking up RWD VS. FWD on youtube. any of the first few videos could teach you alot.

  • tooling around and stunts are undoubtedly more fun in rwd, but i still disagree with you on the cornering thing, especially off a line

  • @stickit2damanleosis I hate to say it because I like my Monte (which is FWD), but BmxDieseldude is correct about the cornering thing. RWD cars will always have a better ability to race better then a FWD car. High hp FWD cars can't launch, and when pushed in a corner, FWD cars understeer pretty badly. RWD cars tend to oversteer, and that helps greatly in a corner. RWD is a much better platform for racing, but you can still have fun with FWD :)

  • @zipper778 well as i was saying before i still believe that fwd is the superior performance platform. although i will agree that when the weight is shifted backwards during a launch that fwd cars lose some downforce. i think this can be easily overcome with a set of stiff shocks. i also think this makes fwd superior because as soon as a rwd platform loses traction, its all over. theres no quick recovering. but thats just my opinion and i dont expect everyone to agree with it. i like fwd better

  • @stickit2damanleosis Sadly, FWD will never be the superior platform. The best RWD cars have put down more hp, run faster 1/4 mile times, have higher top speeds, and handle MUCH better then the best FWD cars. There's nothing wrong with liking FWD cars, it's just that there comes a time when you have to admit something. Also, high hp FWD cars are horrible for street racing. I don't consider my Monte as "high" hp, but with 348whp, I can't launch that Monte on the road to save my life.

  • @zipper778 putting down more hp and running faster times has NOTHING to do with fwd, rwd, awd, positraction, unitraction, or limited slip. you can put more motor in a rwd vehicle because you dont have to try and fit the motor and the transaxle in sideways. i think its pretty obvious why rwd is used more often. its easier to put in, take out, tinker, rebuild, and repair a motor that is on a rwd platform, and more room means more motor.

  • shock and awe....i wish my grand prix had this power...

  • More to come this spring. New powertrain is planned to go in late April.

  • so r these cars dependable?

  • As dependable as you want them to be

  • bet u cant do dat N a ford honda r toyota fwd drive I HATE ford toyota and honda

  • i love it i love to see people modify GM FWD cars

  • They dyno'd at 753WHP in October of 2008. That's the most recent video I can find. But for a video of the car and it's record setting run, search "World record 8.65 FWD 3800 GP"

    Turbos in place of the fog lamps...that is sick. :-)

  • And they did that on a stock L36 bottom end too!

  • Nah, as awesome as this one is, the fastest Grand Prix is run by ZZPerformance. Its a Twin Turbo GT, still FWD, running 8.6XX in the 1/4 at about 160mph. Without any nitrous. :-) They went out to Pinks: All Out, and on their final pass, they tried it with nitrous, and blew a head gasket halfway down the track, and still ran a low 10. LOL!

  • Bad ass!

  • I've not cared for CSC setups. Power comes on way too late in the RPMs. you need to overdrive them a bunch and then use a boost controller to limit the peak boost or they are real dogs down low.

  • What psi is that runnin?

  • Dynos were done at 21-22 PSI

  • Ugh, god. This just makes me want to put a L67 in my Monte moooore =[. I dont know enough to build engines, nor do I live near any shops to do a swap =[

  • dam

  • I try to tell people this is what a 3800 is capable of if you build it with a whipple and they think I'm crazy. Pfft, they don't know shit. lol

  • And this isn't even close to the real potential. We're expecting to be over 625 WHP on the new build.

  • whats so great about the whipple compaired to the m90? besides the fact that the m90 pulses air and the whipple compresses and forces it.

  • The Whipple (or twin screw compressors) have a much better volumetric (up to 99.9%) and adiabatic (up to %80) effeciency than a roots (M90)blower. This means given the same displacement twin screw and roots blower, you will more more air, and heat it up less when the twin screw.

    On top of that the W140AX is has a 55% larger capacity per revolution than the M90.

  • a whipple can pump out this kind of power while running at near the same temp. as an m90 on a stock gtp

  • Holy Craplola!! As an owner of a 97 GTP myself let me ask you this.... how in the hell are you keeping a trans in that beast?

  • better yet, how will he ever hook up with an FF drive train?

  • these cars hook up very well even thoughh they are FWD. look up 9 second GTP

  • damn what mods  u got in it?

  • Lots...

  • do list please

  • I'm jsut curious, was the whipple a complete bolt into where the m90 was?

  • It is not a direct bolt on. An adaptor plate is needed. We will be changing to a Yella Terra Whipple Intercooler/Adaptor plate on the current rebuild (completion late 2009)

  • Engineered And Tuned By PRJ Performance! Enough Said

  • The new trans build started last week. We'll be using Gen2 Blues in 1, 2, and 3. We will be going back to the old pawl type spag for the 3rd gear sprag. It looks to at least be less prone to exploding than the ratcheting ones. We had another option with the sprags, but at $5000 each, not gonna happen.

    Work is continueing on the engine. Lots of things have changed. It will be a completly new engine, capable of handleing 1500 HP easily.

  • I`m try to get hold of 3 axis cnc machine. I feel your hard ship. my issue was the diff and input shaft snap at 475whp. I did get about 30,000 mile daily and strip.The f40 has a 1 inch 28 spline input shaft. I am already eyeing a posi diff from the after market. Has you know i working with H-body. 1500HP....LOVE IT!...C116?

  • The block (casting) is better thank the GN 109 block. The 3800 block is also heavier due to more casting at the deck and the skirt. My block is APR fastener. The main jorunal is line bore. The crank is re-balance for manual 7000 rpm. I am very confident in all my build. This i know for a fact ,the block will handle 800+Hp. Its very hard to hurt a 3800 block if you some-what ,know what you are doing.

  • Lol yes they are, You do not need a custom Block for over 500+ HP

  • Very nice!. How is the trans holding up?. whats your mod?. I remember 500Whp days.Very strong engine. :)

  • Trang had been rebuilt 3-4 years before the Whipple was put on. It was getting due for a refesh at that time. After about 6 months with the Whipple, it was having problems with the input clutch slipping, so it is currently in the process of another rebuild, along with the engine.

  • Are you running the "high Energy clutch"?. I believe raybestos has a line of Red disk with kolen steel plate. Typr F fluid work great with this clutch. The type F, fluid has less lube (slipping)additive so the clutch lock up quicker with less slipage and dirt in the pan. You can monitor input shaft in comparesion with the output shaft speed.

    Do you have the poly lower trans and motor mount?

  • The old trans was running the Raybestos Red clutches. Extra clutch in 1, 2 and 3. I would NEVER put Type F in a FWD transaxle. That lack of lube will kill them. We run good quality non-synthetic Dex-IIIh.

    Lower mounts are solid rubber. Uppers are poly.

  • I`m 2% away from completing a 600whp 3800 turbocharge due to weather condition. The project is F40 (6 speed). I had no luck with auto trans and hi HP so i am starting over with a gear box.

  • Other than blowing apart the 3rd sprag (which was the major problem we recently found), the trans was in overall good condition considering 3-4 years of use. The previous trans build, which was done by someone else, had several issues we found. Yet even with these issues it held up fine.

    .

  • I strongly know for fact the 4T?? trans can be modified to accept a 1000+hp.I use to deal with chris hoback @ ratbestos - application test. great guy. I`m planning a 2002 park ave ultra,so your trans will be use full.:)

  • Don't really have any way to tell. There was a lot done all at once. Everything needs to go together to work properly to get good reliable results. You can't just bolt a whipple on and expect the engine to hold together.

  • no times yet?

  • No, the car has been down all summer due to a failing transmission and a broken valve lock. Engine was just pulled out this weekend and torn down. There will be a new IC and adaptor for the Whipple going on along with several other improvements with the rebuild.

  • 536 hp???wow,on a dyno too,probably close to 600 hp at the crank.that will probably out run a new Z06,right?

  • We see a 20% drivetrain loss with the automatic transaxle, so figure closer to 670HP at the flywheel.

  • damn,so that'll probably tear up about anything you throw at it,whats it run in the 1/4 mile?

  • Hasn't run the 1/4 yet. First time out (at an 1/8th track) it broke the drivers side axle. The trans also is having issues with the input clutch, so it is getting pulled out sometime this summer for a full rebuild with several improvements. New custom axles are also in the works for it. Probably won't get to the track til late fall.

  • how much have all of the modifications cost?

  • I honestly have no idea what the total is. The car is one of my customers car. At a guess, probably over 20K. The car had progressed through several phases before the Whipple was added.

  • well thats not bad considering that it will outrun cars that cost well over 10 times as much.

  • that sounds bad ass!!!

  • The kit was purchased from animuL Performance. It required a lot of fixes to make it work correctly. From my understanding, it is no longer being produced.

  • atta boy! its cars like yours that make us gp owners look badass!! niiice!!!
