ok guys, as some of you kno, i recently bought a crap load of parts for my balt, im at full bolt ons. here they are.

zzp 1.0 pcm
injen CAI
GMPP cat back
bad mab header
phenolic intake spacer
zzp dual pass plate
zzp s3 heat exchanger
zzp 3.0" pulley
gm stage 2 belt
zzp TB spacer
option B tank/bracket
NGK bkr7e v power plugs/ 1 step colder
seimens #50 injectors
zzp top motor mount
zzp front/rear tranny mounts
AIS stage 1 meth injection system
eibach sportlines

my question is, i know i can run a smaller pulley, my s/c is cool to the touch after a few pulls and i love it. would i be able to safely drop down to a 2.6? or just drop to a 2.8? my next upgrade in a gm upgraded clutch btw.

 

Honestly, get s custom tune and go to a 2.9 which will prob be the most u can go.... Safeltly without getting high idcs. I ran the 50s at a 11.2 afr and idcs were 96% on a 2.8 and also a 2.9 with idcs of 93%

 

have fun doing ur clutch it's kinda of a pita

 

Get 60's and run a 2.6". So much fun haha.

 

Its not that bad.

 

dropping the cradle is a pain to start with. I'm doing a complete overhaul of my car and to get the trans out and down was pretty bad. Bolt ons are cake compared to that work

 

Lol.. this man has replaces 100+ Eco clutches not hard even on the ground lol

 

Wanna come do mine? Lol

 

Sorry I am bot allowed where you live...... Jk jk

 

run 80s

 

No need for 80s unless he runs ethanol.

 

zzp said theres no need for anything larger than 50's on a m62, unless your running e85. i might just got to a 2.8 then and try that. its winter time, im just trying some things out when the roads get nice once and a while and in spring ill have a custom tune.

 

Lol....... I swear sometimes.... Just because zzp says somthing doesn't mean its fact.... 50s can hold a m62 over but there's a lot of things that come into play with your tune .. elevation, timing, afr wot, ect if your tuning 12.3-11.9 ages I'm sure you can do it on a m62 but your asking for issues. The heaton makes heat so therefore a leaner afr plays a big part is the kabooms in the lsj. So 60s are a whole lot better because not only do you have room with the 60s but your not maxxing nor are you getting static injection. Having 60s give you more leeway.....

 

Let James (CCSS3) tune you, and get a 2.6... I promise you won't regret it.. and possibly 60's..

 

This.

I'm running a 2.7 Right now, on 60's.

My supporting mods are:

Custom Tune
Option B
Dual Pass End Plate
Stage 3 ZZP Front mount H/E
NGK Sparks
2.7" Pulley
60# Injectors

& I'm pushing 285 ish

 

Get 60s or even 80s for future upgrade

 

dyno sheet? I got all that and a 2.8 but doubt im pushing that much power. still need to dyno

 

Will be dyno'd this summer. I don't have a "Bought" Tune, It's my own tune.

 

I got ya. Yea I have a custom tune by BYT as well.
