yeah chef take a good pic so i can make sure i know where to put that gtm pulley mod in without it being an issue..thanks

 

I bet alot more than 500 DJ or 460 on a dynodynamics!
Tyler, why do you think you need the pulley mod? I can run cleanly to 17psi with no belt slip. Unless you are making more than 500 hp, its a waste of money. Spend that money towards some upgrades!

:

 

Not sure how u and GTM were making more than 12-13psi with the 2.87 pulley without changing the 32T cog pulley on a non rev up motor.

The pulley is ONLY meant for 13 psi max and somehow u guys are getting 15-17 psi? A bigger blower increases volume but has nothing to do with increase in psi. Therefore, if a SC trim is making 400 whp on a 2.87 at 13 psi then the only thing the S-trim or T -trim will do is make +450whp at the same psi level. Does that make any sense???

 

I tried take a picture but too dark outside. I will try get a better ones tommorow.


You making 17psi? wow that's surprised me bro. Where is your redline set at? and what breather mods?

Yea i saw your engine bay picture before, but you took the picture off. haha you are the first person i heard no issue with belt slip and making a huge power.

 

this is where I scratch my head and say hmmmmmmmmmm.... 1+1= 1??? Things dont add up here.

 

I like to do stuff at midnight...lol ha

Tyler here is pictures.





From the side view








Had to cut out that much. IP just trim the hood little bit at the first ( which it didn't rub when it was at idle....but everytime i pulled the car, pulley hit the hood again so one of member on the forum and I ended up cut that big...lol Can not really see from picture, but pulley is now kinda beat up looking but still works tho

If you willing to install slipping pulley in future, i do recommand install at under the belt. Which you see two pulleys? bottom one.



And here is crappy cell phone pic. 2.87 one side machined by local shop. Shop recommand that paint it again but i didn't really care.

 

ya, i had the same issue with the 2.87 pulley not spinning freely. I just added a very thin spacer inside and it works perfectly. The GTM pulley is nice but I wish they had told me it didn't fit perfectly. I had the freakin serp belt ripped to pieces had they told me it required modifications. Chef, u should have just taken off the cam cap cover and sand it down so u didnt need to cut the hood.

 

Spacer? i did actually call superchargersonline about using a spacer when i had trouble, but they didn't recommand it. They told me it's something with newer model? or older? blah i forgot.

Oh!!! gotcha ( took me 5 minz to figure what you are saying about sand down cam cap cover, i was like how that will work?haha ) That's good ideal...but too late...

 

If u use a thin spacer then u will be fine bc u aren't moving the pulley out that much. At first I used a little too big of a spacer and the belt jumped off the pulley, lol. I think that's how I messed up the belt, hehe.

 

Belt jumped off the pulley? Wow haha

 

Chef,
My blower came with the GTM pulley but I didnt have to cut the hood at all. it fits fine. Ill take some pix and we can compare.

oh p.s- I thought I blew my motor yesterday. Smoke everywhere!!!! I turned the engine off right away( thinking, **** my life, I blew it! ).. I brought it to a shop near me and my oil pan was cracked!!?? idk how.. good thing I shut it off fast. No damage to the engine! thanks god! picking it up monday! and Ill take some pix!

 

^hahaha glad that its was not serious.
