To whom may it concern . . .

All:

I will make a long story short. My GTP drowned at the dealership on STORM season back in 98. Got it real cheap(was not as strong as a normal GTP) but was good.
This GP had 79k miles on the odo When cruising the transaxle shifted to neutral the engine was debilitated because of what happened originally and consequently busted.
The car was sitting there for 6 months. Got a payment for a
special assignment and then I decided that if the imports can have 300hp+ and 150MPH+ V6's cars so could we. I contracted a Chief Mechanic from my Local GM dealer to give me what I wanted.
A 300HP+ and 150MPH+ GP.
What I got was a 295HP(as far as what the Dyno said)
and so far 138MPH car. Not bad based on what I
wanted originally.
The only modifications the car has are on the engine, SC, suspension and transaxle.
The car still has the Catalytic Converter and stock looks as you can see:





The only signal of modifications are the SLP spoiler that I have not painted yet cause I am waiting for the hood, NOS and related hardware(want to paint it all at once):



The small 3.2 Thunder SC pulley:



And the slotted/drilled discs:



I have a small 2.4" pulley for special ocations(only used once so far):



For those if you that think that V-Tec is only at the cams. How the hell then the ECU(PCM) knows when to fire. Maybe I used the term incorrectly because my GP can retard or forward ignition firing depending on the Performance Shift Setting, TCS and driving conditions. That is what I understand Variable Ignition Timing is, if that is not it then excuse me.
Sorry to disappoint you because the car does not have any codes, KR or malfunction at all.
Also I know that the transaxle only has 3 gears and OD. But if used wisely(PCM Wisely) and the correct gear ratio you can get excellent performance. Among other things when the Performane Shift is engaged my transaxle will shift from OD to 2nd gear on demand or from 3rd gear to 1st gear on demand. That is what I got, because how
you can achieve 138Mph at 4750 on a std 2.93 transaxle or 3.29 for that matter without the correct clutches and ECU(PCM) support on this kind of vehicle?

As a matter of fact my car came from factory 3.29(you can check the VIN:1G2WP5215WF267055) and I lowered to 2.93 as recommended by the technician to achieve easier the higher speeds that I wanted at lower RPM’s .

I have invested so far on engine, transaxle and SC and related hardware around 15k.
I am getting what I wanted. If you want to believe it fine, if not I am the one driving this import(big cars) killer around. I would really appreciate you people that if do not have
anything good to say please do not say it. This site is supposed to be a meeting place for people with similar interests and tastes and have a great time. Let’s keep it that way shall we?

Here is the car front with modified HeadLamps(They have hyperwhite small bulbs like VW to iluminate when headlamp is not on). I have disabled DRL:

This is part of the cockpit:



Will keep you posted. . .

could you please list your mods instead of just saying "The only modifications the car has are on the engine, SC, suspension and transaxle.The car still has the Catalytic Converter."

[GTPCatz]

"The small 3.2 Thunder SC pulley:"

And again what is a thunder pulley

[kilroypr]

Have it your way. No more time to waste on this. You guys know your stuff. I will find out exactly what mods they installed for my general knowledge.
I used a GM dealership to get waranty on the job. IT has 36 months, 50k miles waranty.
That is what is most important to me.

That is what the pulley has written on the side. The small markings is a script saying thunder. That's it.

No more BULL. Do not waste your time reading this post.

Go have a great time.

OMG LOL

It doesnt say Thunder!
It says Thrasher!!!!!!

Now in your picture you posted it may look like thunder but its not!
I dont really think you own a GP!!!!!!!

[kilroypr]

Whell BUD. I have 4 cars. The 98 GTP Pictured here, a 93 Z-34, 99 S10 Blazer and 69 Chevelle.
Well I have to wear glasses and I would want it to say Thunder instead of trasher.

[kilroypr]

Look what I found on another post to AF:

(Post #9)
Getting 310 at the wheels is not that hard of a task.

Cam
Pulley
PCM
Intake
Exhaust

With the right parts and good tuning that's all that it would take. Last time I dynoed the car it pulled 291hp at the wheels. That was without headers and on 93 octane.

What I am looking for here is that if we can lure people to gp's and let them know that for a small amount of money(what ever that would be based on your project or others) could have a M3, Tang, Honda, etc etc etc. Ass buster on a tight slim package.
--------------------------------------------------------------------------------

People already know. It's called clubgp. Plenty of low 12 sec GPs on that site. A few 11's GPs and 2 10 sec GP's

If you want HP recipes that's the place to get them from.

Looks like the guy at the dealership knew the same recipe that Ripns12 know. Both are getting the same performance with a minimal mods amount and from what Tim says here he got ~291HP with 93 Octane and no Headers on. Interesting...

['00' GTP]

OK... I think that I have to step in here.... I believe that with a 2.8" thrasher pully that you can pull 300HP.........

but for someone that has a GP and wants it modified you should know that Thrasher is a name brand of pully... You would realy want it to say Thrasher and not thunder.... thunder means that it is a knock-off of the real thing....

the other thing is that I don't think that you could realy get a true HP reading if you have the factory exhaust... you would have too much backpressure and it would begin to cut off... I had a 3.0 pully on my car... way too much bang... went down the drag strip.. about 4,000 rpm's it started cutting out and didn't go any faster...... a 2.8 would be way worse... and if it is not you need to get in there and replace your heads, cam, and basically everything that is connected to your engine.... and I would strongly advise installing a intercooler.... or you will have a POS GP on your hands....

another piece of advice Factory GTP's only put about 200 HP to the pavement... they loose like 25% in the drive trane... that would mean that you would be pushing like 370 HP at the engine......... I would also like to say that I don't think that you know shit about GP's..... stop trying........ b4 you give advise you need to know something first....

if you want to sound smart I think that you should go over to club GP and figure out what you are going to say over here... you still won't know anything, but you will be learning and mabe teaching the right thing to the people over here.....

['00' GTP]

sorry but the other thing is that there is only 1 GP that is under 11.00 in the 1/4 mi... and it runs a 10.97........

Wrong. On both accounts.


Copied and pasted this right off the 1/4 mile list. Where have you been that you missed Ken's post.

Well whatever. There is people that have used stuff that I have used and have served them. Is your prerogative. If you know it will not work just step in and correct me. I will learn from you.
As I learn from people like Ripn12s and The Burning Rom among others.
Thanks anyway, I do beleive what the Ripn12s said about his car. In my case I am not aware of all the mods cause I wanted something that worked on a dalily basis and with waranty.
My job does not give me a lot of time anymore to be building stuff around.
The car broke, i asked what they could to at the dealership. They did it and the GM parts have 36 months and 50k miles and the others have their respective vendor waranties, was quite expensive based on The Burning Rom assesment but the peace of mind worth it. Even it has road assistance included
