hey is this pulley ok for my ssm90 setup?

[DBGP]

hey my ssm90 kit awaits to be put on my car. I got a gtp belt setup for it, and i have a stock gtp pulley (3.5 correct me if im wrong.) Would that pulley be fine? My mods will be 2.5" dp, ubend delete, mufflers, CAI, ported LIM and s/c. If its too small i would just order a ssm90 pulley from zzp, if i did i would get the 3.8. On their site it says all ssm90 pulleys the same as a gtp pulley .3 smaller? or is that bs? Im just tryin to make sure here i dont want my KR to go though the roof. thanks

stock pulley is 3.8". with your mods, that's about all youre gonna get away with.

 

[matt5112]

many find you need headers just to run the top swap with the stock 3.8" pulley...

leave the stock one on but get headers.

 

[DBGP]

Ok thanks! Yea next upgrade will be headers, colder t-stat then I can maybe drop my pulley abit

 

[matt5112]

3.6 is about the best you can expect from a top swap with headers as your only mod.

I'm running a 3.8 on a top swap with headers, ported TB and S/C.

 

[DBGP]

Yea 3.6 is what I had in mind, where the gains noticeable compared to the 3.8? Also how's the ported TB? I've been wondering on if I should get one or not.

 

[matt5112]

You attempt to smooth out the MAF hump in the TB.

You'll need a street tune if you do it.

Helps with throttle response.

with my mods, i can barely run the stock pulley

What timing and 02's? OP 3.8 with stock mani's, 3.6 with plog DP setup and 3.5/3.6 with headers. intercooler or cam after that piont and larger injectors and pump rewire.

What timing and 02's?

fat 02's 960's-970's sometimes even 980's

15* wot timing

2.5* of knock

From the sounds of it, you are looking to just run a regular pulley on a ssm90 kit?

The ssm90 kit uses special pulleys. You cannot use stock pulleys as you need the belt setup for that. You would need the balancer or crank pulley from a gtp and the idlers/ tensioners/brackets to run a supercharger belt.

I would start off with a 3.8 pulley or higher and go from there.

 

[DBGP]

ok yea il just run the stock 3.8 pulley, i have the belt setup for my m90, i have all the tensioners i need. thanks guys

Get a wideband.

980 is probably bad though...

My car would knock when 02's went over 960. You can knock from to much fuel.

I have a wideband, afr is around low 11's

if i try and take away fuel, it knocks more

 

[matt5112]

Thats about where you'd want to be...

Your engine must not like you lol.

Have the heads ever been off?

 

[01gpgt01]

Wonder if you have an exhaust leak near the sensor tossing off the reading?

 

[FoSHO99]

No, narrowbands are just that ****ty anywhere else but light/no throttle.
