It doesn't always knock... you know I can turn back the timing, up the pulley and the car never knocks. That was just to see how much I can squeeze out of it.Originally Posted by 98GrandPrixIraqVet

You have a baby cam.
And need a stronger valvetrain.
Get at it.
You'll make 30+ more WHP easy.

nick you forget to add injectors and a better tune to your list
05-19-2011
Ok...so...50 more horse? LOL
And a smaller pulley.
I'm just saying.

I have an XP cam with 105# springs. You're telling me to change out my cam to a bigger one, which would require headwork, springs, a full tear down of the motor to the shortblock, and other supporting mods to maybe make 30whp more.
At the end of all that effort I still have a horribly inefficient blower and make less than what the TVS will without going through all that hassle.

SSAC Headers to stock grand prix catback
05-19-2011
Best I can find right now. Thats on a 3.25 pulley stock l67 injectors 12.3 afr with a lean out issue and yes injector drop off. so I droped 2-3 degrees of timing to be safe.I was trying to figure out, and pulled my 60's out to see if they were the issue(I was runing e85 about 8 months ago). If your really interested I have over 200 scans on my home CP im at work. Anyways heres the car and mod list http://www.grandprixforums.net/green...-gt-42587.html oh and on a 3.25 I run 10ish PSI depending on temp

Probably headers.
But jesus...you'll gain 30 horse from just headwork.
Your not looking at the big picture Flakey...ported heads/bigger cam/injectors/pulley/retune...now your looking at over 50 horse. Now your probably past your TVS swap...with the same "crappy" Eaton.

You're telling me to ditch my XP and 105s to do a full motor tear down that will require lots of money and lots of work and I'm just not interested in doing that.
05-19-2011
Then...this whole thread is boring...just like stock heads and an XP.
05-19-2011
I thought you didn't care about the money...
05-19-2011
You have an intercooler... How is that at all comparable to me or close to what I asked?
05-19-2011
I don't care about the $500 I may or may not get for my GenV with the MPS and pullies. If I don't get what I want for it I'll hang it on my wall.
05-19-2011
Ohhh sorry to be so boring... btw what has your big cammed, headworked, properly built Grand Prix run at the track? What did you make on a dyno?
05-19-2011
HMM this might take a while
05-19-2011
i think this is a LULZ moment?

My car has gone 12's on all season tires full weight street trim on 93 pump gas. I also made over 300whp using the same recipe...
People are real quick to attack my methodology...
05-19-2011
Not really just saying the TVS is kinda pointless until the tune and injector issue is fixed 1st.
05-19-2011
129 FWHP, ran 14.7 @ 112.
If you must know.
