Looking for an asp big boy pulley that uses a stock modded oem pulley.if anyone is going to a 190 let me know.

E55Bullet

haha all the talks about a bigger pulley and you want one? An asp 180 measures about 185 btw, at least mine did..

skratch77

I need it for an attempt to get in the 10s. Your 180 measures to an 185? Or an asp 185 measures to a real 180?

Im looking for a true 182 pulley if anyone makes one

E55Bullet

I think ASP will make anything you want. Mine is an original ASP 180 that measures 185mm with a string all the way around

skratch77

If yours measures 185 I think they sent you a 185 because they made a few 185s. Iv had there 180 and it was close to a true 180 once measured.

E55Bullet

Thats what I was thinking and thats why I measured it as soon as I got it. Another member did the same thing with his 180 and it measured 185 as well. who knows..

MB_Forever

I wouldn't go with 185 mm.... 180 mm seem to be the sweet spot for 10s

E55Bullet

I'm guessing that a lot of the cars with larger than 180mm are doing other things than the 1/4. I also would guess that there are more 55's in the 10's than the ones we know of..

skratch77

Well its kinda a go big or go home thing.I have a 178 on her now and just did 4 pulls and on the 4th I took 4th gear to about 5800 and the a/f was 10:7 so there is plenty of fuel there for more boost.

E55Bullet

Its about time you see the light

skratch77

I will admit that part of my problems before were from the car pulling timing and not 100% from the heat of the pulley.

I went from trapping 116 with a 180mm and then trapping 119 with the same tune on stock boost.

I just did 3 pulls back to back and the car made within 2 whp on all runs.

Already?? Hahaha good stuff. I just got home, uploading clips of the pulls

skratch77

Good times kid !!!

i see your sig that u have stock TB. i think going for 82mm TB is better then changing from 178mm pulley to 182 or 185. power from TB is ay more an better + u don't heat your S/C

Hammer Down

^^^agreed if you switch to a 82mm and get a new tune you will be knocking on the door of 11.0-1 and then switch to a lightweight 16" drag pack or any 16" drag pack for that matter to help you with your 60' and 10's will be yours for taking

skratch77

Iv had a 82mmtb it made zero gains on the dyno,the gains people claim are with tb and retune and would of prolly made the same power with the stock tb and just retuned it with more timing and less fuel.

Shardul is over 500whp and 600rwt on a stock tb and 185 pulley.

EDIT 190mm pulley

skratch77

Here is my last dyno and its tuned on the rich side and pulls all the way to red line.

This dyno reads low and the other dyno is a Dimas car done the same day.

ok then, work on your 60' .009 off a 60' on my car made a .06 difference in my 1/4 mile et.

so in your case if you knocked off .010 ie 1.71x you could possibly run 11.35 so imagine if you ripped a 1.67 60'

skratch77

Will see what happenes at the dragway.Newengland drags redid the whole track with brand new pavement all the way down the 1/4.

If I could pull a 1.6 60 ft that would be a low 11 pass the way it is now but I had traction issues all last year at my track.

GL bro "you can do it"

after installing a larger TB. you should use star to make readaptaion. goinggtom stock TB to 82mm will give u 15rwhp with adaptation by STAR and more than 30rwhp with STAR+ tune.

and sometimes it takes more than 100 mile for the car to recognize the changes.

i can bet that it will show more power later on after driving it and make it adapt. the same as intake filters.

these methods were tested.

Is 190 too big, I have a custom maked one with the OEM pulley?

skratch77

I wanted to go 185 max but would love to see some pics of that 190.Did you ever run the 190 at all?

How were the temps on boost?

viper04

I will take some pic and post it up later today. Ran it on the car was good, but hard to keep AIT in check with stock E/C. AS you know with these car if you can keep AIT in check and have a good tune and fuel up top, man these cars are unreal.

Here are the pic's, I have the 190 (right) next to my 180 ASP with the water pump pulley just to show the water pump pulley size needed to clear the crank pulley. I would stick with the 180 to 185, like you said. unless you have a "Water to Air Ice Box Reservoir in the trunk". Like what the turbo guys use. Here is a link to what I'm talking about.

I did have some logs with the 190 on the car but can't find them. If I find them I will post it, this was back in 07. R-flow use this set-up, the "Water to Air Ice Box Reservoir" and was able to keep is AIT under control in the FL heat.
