what are the claimed gains for having the GMPP honed header?

and is it worth the 280 bucks CDN

firestorm

i have a hardly used on for sale in canada;. i think it was 30 cfm more. warranty freindly tho. good stage 2 upgrade. useless if going more tho.

MfZx25z

yeah but if you want to go faster later down the line its not worth it

I've heard it's not that great...are you looking to stay warrantied or just figured it'd be a better part for the car?

R&C_rallySS

I have the GMP manifold installed. Its not much of a gain but is well worth the gain and keeping warnity. I would say its good for a all GMP cobalt. I have no problems running mid 13s all day long. Trapped at 108 so the GMP manifold must not be to restrictive.

zzp....

So its good to get the gm headers.

I have the GMPP header.... I made 262/241 with that header!

Co|3aLt $$

are you stating that or asking it? (header...btw... unless you have the 6 or 8 cyl. 'balt)

with stg2 or what?

M-Dub

Oh, I'm far beyond stage 2! But I am still running the GMPP header!

Dirty Sanchez

well i got my car last year, put hardly any KMS on it. its around 8500..
so i want to keep my warranty for now.

i want to max out the mods to make it go fast but still remain under warranty.

so far i have.
stage 2
injen intake
gmpp sport exhaust
ingalls
projectors with hids

so right now im pretty safe as far as warranty goes, i can stip off the ingalls if i have to when i need to take it in.


i was thinking maybe getting stage 3, but in my area the highest octane i can get is 94 from sunoco. so im not sure if its worth having stage 3

M-Dub

GM's stage 3 is a complete waste!

My mods for my 262 run:
2.85
Methanol Injection
GMPP Manifold (custom ported further)
ZZP Downpipe with cat
2.5" Magnaflow Catback
K&N Intake
Custom tune from Area47

i disagree, i think the cooling part of the stage 3 is a benefit.

M-Dub

What cooling mod... the dual pass! It's a joke! I've seen a full GM stage 3 car dyno!

QuikSilverSS

The dual pass from the stage 3 isnt a joke. Its got proven IAT2 drops.

As a whole though GM Stage 3 is disappointing without the Nitrous part, But the dual pass in conjuction with a cobra heat exchanger is great for cooling, add meth for the ultimate chilling effect....not to mention the gains from bumping the timing

M-Dub

All of the cars I have seen with the dual pass, saw little to no drop in IATs the full Stage 3 car actually was hotter than I was! And at the time I had NO cooling mods (obviously prior to methanol)!

I installed the gmpp manifold. I'll put it this way, I'm glad i bought it used and only spent $150.

It's not worth the time or money to buy a new gmpp manifold, especially if you are going beyond stage 2. I also have a ZZP downpipe. it is awesome. Really makes me wish i went with the zzp header.

Area47

the volume of flow is greatly reduced with the dual pass.

distillion

ive got the gmpp exhaust manifold.
no complaints and im far from stock.
matted with the rebel downpipe and gmpp performance exhaust.
sounds good and acceleration is pretty stout.

Dirty Sanchez

hey distillion, its sith ss from our ontario site.

i just want to max out my performance and keep the reliability.

if gm is gay and wont hold warranty becasue i added a non GM downpipe, well they can suck a huge meat stick.

distillion

hey dude. My warranty is in tact
depends on your dealer.

like i said, there are other pieces that yeild more power, but the gmpp manifold is pretty decent, fits perfect, holds warranty and gives you a lil more pep.

like i said, with my setup, i have no complaints, im far from stock and i get compliments on how good my car sounds.

for the dual pass, we proved it to work.
i have another guy here in the gta, same pulley (2.7) and generally the same boltons.

i cooled down much faster and operating iat2 temps were about 10-12 degrees cooler.
idle temps were about 5-10 degress cooler.

figured this out on the way to the track.
also at wot on similar conditions my iat2s were about 15 degrees cooler than him give or take.

Dirty Sanchez

what do you suggest i do for some mods?

also, this summer i gotta check out some of the meets, or cruise down to the track with you guys when you go!

distillion

pm me on occ with yer setup.
and yes u should make it out to the meets, we got tons of **** lined up for spring/summer
