Got a deal on getting my stock eaton ported. Put it on the car, stock pulley, and what a hell of a difference! On the dyno, stock tune, it made 232 at the wheels. No other mods except K&N filter in stock housing.

Today scored a ZZP intake local, and that made a decent difference too.

Next is a 2.85 pulley.

What supporting mods do I need to do besides injectors, tune, and harness?

 

Downpipe, Dual pass, Option B and heat exchanger

 

I would go with zzp huub and 2.8 pulley, 60's and a tune. Should go ahead and put dual pass and a phenolic spacer. you will then be good to go!

 

I suggest smoothflow for your pulley.

header/downpipe combo, dual pass, heat exchanger, phenolic spacer.

 

Already got a smoothflow hub and a bent 2.85 pulley. Just need to buy a new pulley....

 

I will have my 2.9 for sale. Has scuffs from trying to get belt on but its straight

 

Why you selling the 2.9?

 

I got a 2.9 and brand new 3.0 pulley just saying lol

 

I would swap injectors right away. They come maxed out from the factory. Not sure if your making them go static with a ported blower alone. Did you do any datalogging?

 

Nope. All i did was check AFR. it was still around 10.9-11.2, which if i remember right, is kinda fat.

 

2.8 time!

 

I am curious why most guys want to go 2.8 pulley than 2.9 ?

 

I got bored.

 

AFR??? I'm assuming then you have a wideband then? My original comment still stands. Change your injectors, and get a decent tune for that blower. All that additional volume your blower is taking in is most likely causing those rich AFR's, and making your injectors go static.

Other than that....I recommend getting as many cooling mods as possible:

-ZZP's phenolic intake mani spacer

-Dual Pass endplate and option b tank reservoir

-Large Heat Exchanger (or run dual heat exchangers)

 

Thank God for all that cooling mods that I already put them in. It's VERY worth it!

 

i agree i need injectors. This was measured on the dyno as i do not have a wideband.

 

your idcs are gonna be maxed out with that extra airflow. but if you plan on getting 60s, youll have no issues. dont go with 42s. i saw 115% idcs on just the gms2 pulley with 42s. i think i saw you on race 850.. whos gonna do your tuning??

 

Gotta find someone still. Not a fan of mail order. and yes im on race850.

 

theres a shop over that way thats a vendor on 850 that does dyno hp tunes. i would, but i rarely make it over that way. glad to hear youre liking the power your making though man

 

well im gonna pulley it too. and put a downpipe on. then that will be it. 300 at the wheels will be good for me. I should be close to that. well somewhere between 250 and 300...
