i do the same with mine and have no problemsOriginally Posted by Bio248

his car also has alot of mods to help flow. on a stock car, i would not recemend it.
seeing how much hes knocking with all his flow mods would make me want to stick to the stock pulley for a while.
why not just get a scanner and see how much your knocking??? nobody can really tell you for sure. that would be the easiest way to do it
03-03-2009
i agree i wouldnt drop a pulley if my car was stock, but with the mods i have i think its fine but i would not drop pulley sizes with a stock car
03-03-2009
you dont have near the flow mods as bio and hes knocking up to 5* you might want to get yours scanned.
remember, knock pulls timing. timing is what makes power along with other things. why not run a little bit bigger pulley with 0 kr so its not pulling timing and be just as fast???
03-03-2009
what size should i run then? and im getting the pcm from intense friday would it be safe then?
03-03-2009
What mods do you have??? A cold air intake that sucks nothing but hot air and a u-bend deleate? That's not a lot.
03-03-2009
You can't guess. You have to have the tools to find out. A scan tool or a scanner on a tuner.
And when you start dropping pullies all a mail ordered PCM is doing is loading it with fuel. I'd like to see some of you guys reactions if I or any one would do a custom tune for you guys.
You can not tune a pcm in the proper way without knowing the conditions that are present. And those conditions change everyday. Ask anyone that has a tuner. They don't just use it once and stop tuning. Because tuning is an on going thing. Even if you are not changing things out that could affect the tune!!!
Oh. You say you're not knocking? I belive you. But what's you AFR on a wideband looking like?
That's what I though. You don't know.
03-03-2009
the tune means everything!!! you can tune out KR with more fuel, but it wont be running the best that it could.
03-03-2009
well thanks for the input guys, i figured the vendors would be overly biased. i think i'll just put on the k&n and end my modding there. i may even be putting it on the market already so if anyone's interested in a silvermist 98 GTP coupe with 15k miles let me know. Looking for $8,000.
03-03-2009
I asked a lot of experienced GP owners and a few who own tuners/scanners. I wanted to drop a pulley at first when I got my car. I was told bye bye motor if I did by everyone.
So I went other routes first. I just bought a 3.4 to put on and I am still being told I am pushing the limit. I have a 1" TB spacer, TB heat shield, Colder plugs, 180 T-Stat, Wizaired CAI, Ubend del, Cat del, and Borla exhaust.
Since we have everyone discussing this am I really pushing it?
03-03-2009
heh...well, for 8K...I might be interested
I'll trade you straight up...I'd always have liked to start over...why not do so on a car with 15K on it
I'd keep it to be honest with ya man...you've got the lowest mile used GTP I think I have ever seen IMO...just a few more mods will want you keeping that car more and more
03-03-2009
I'd say if you had a tune and a Downpipe then you'd be pretty safe IMOI asked a lot of experienced GP owners and a few who own tuners/scanners. I wanted to drop a pulley at first when I got my car. I was told bye bye motor if I did by everyone.

And i'd agree. But I think a set of headers or ported intake manifolds would be even better.
03-03-2009
i can really care or less what anyone says or thinks to be honest, my car runs great so keep your tuning or whatever going good and ill keep my car running just fine the way it is and when or if i blow my motor dont worry everyone on here will know, and as for you TDC racing you will be the first to know when i do =)
03-03-2009
Well that's nice to know. I'll keep that in mind for when ever you're asking a question on the forum.
03-03-2009
you will not blow up your car with a 3.4. i have been running untuned with my 3.4 for almost two years with around 5-6* of knock. i beat on it daily and it just takes it as it comes. maybe im lucky, but i dont think a 3.4 is a big enough step for it to matter. hell, SLP put a 3.5 on some GTXs with just an intake and some rockers. that has got to tell you something.
Bull****, i've seen it happen for years on ClubGP anf its happened to a few hear. Even good ol' PRJ could tell ya some good horror stories.
Then again in your defense, you actully have good flow mods. The person in question doesn't have ****. Your mods are helping way more than you might think. I wonder if some of your knock is false too, I know your running Higher CR but still on 93 octane I could see it being even lower than that. Hell 5 years ago with similar mods and lower CR (L67) I ran 93 octane with 0 KR. I never had much of a KR issue at all until OKC pretty much got rid of all the 93 octane stations and used this piss water we have now (91 octane).
ZZP = 48th Street Corner Whore...
Ain't that the truth....
what size should i run then? and im getting the pcm from intense friday would it be safe then?
You're still asking this? Haven't you learned anything yet? Have you read any of the posts on this thread? Leave the damn pulley alone, spend money elsewhere. Jeeze man. Don't mean to bust your ass but listen to people that know your car way better than you do.

I'd say you need a 3" DP or best yet a set of Headers with a nice DP. That will help quite a bit. From there scan and plan your next move. If you're at pretty much 0 KR, you should be good.
Your stock DP is the biggest restriction in your exhaust system. Your manifolds ain't the best either. I beleive PEMs and P-logs are a waste of money so I believe in getting Headers w/ there DP and you'll cure all the exhaust restrictions in one shot and i don't cost much more pending on what headers you buy.
03-03-2009
Yeah headers can be had for cheap but if you can port you're own then you may be able to move foward a little with those.
03-03-2009
im saying on this discusion but im prolly wrong im always wrong but real stubern with things but its cool i guess but are these something that would make it run better that your talknig about, ZZ Performance
03-03-2009
take it to the track. im sure my stock pulley set up will out perform your 3.4 set up
atleast scan it and see where your at, you dont what is going on inside the motor.
