I want to see what everyones looks like, (aftermarket pulleys) We all know what the stock one looks like.

Let us know what boost you are hitting

I'll go ahead and start with my buddy..We did his Redline today.
2.9 From BilletFlow, Beautiful piece IMO..and was somewhat hard to install because it is meant for a "interchangeable system"

2.9" @ "prob. 15-16psi" im guessing... his boost gauge doesnt work right currenty**

 

Did you have any problems putting it on? Mine won't go on like it is supposed to.

 

that looks damn good SilverSS.

 

So you really have to remove the S/C to swap out the pulley?

 

the NGK BKR7E plugs, where did u get them??? Do they have to be those plugs when going with a smaller pulley??? and are they Iridium or copper???

 

yeah its pretty easy to do.

 

They dont have to be those plugs, those are one range colder Iridium plugs found on SFPH website...although i think they say on the site they are Copper..a bunch of us have concluded they are Iridium, but I havent got it dynoed yet, but power delivery is smooth throughout the powerband, and I have the plugs gapped at .035

And Yes, you will end up removing the supercharger, its not hard...disconnect a few lines, and unscrew 4 bolts. Its worth it in the end...For those that have not removed it on the RL..you guys got skill. lol

And for Chevypowered, are you trying to put the 2.7" on? b.c i think you may need the snout machined below a 2.8....We had trouble with his pulley, believe me....

but the ZZP press on's are a breeze.

 

What kind of problems did you have?

I was told that the inner-diameter on the Billetflow 2.7" pulley is the same as the 2.9" pulley so there should not be any problems fitting it over the snout.

 

with the BF pully as long as you dont go below a 2.7size you dont need to change the size of the SC snout

 

Thanx, curious though I thought iridium plugs can't be gapped the tips are to sensitive? If they were copper they have a brownish look to them if their iridium they would be silver.

 

How did you determine that they were Iridium plugs? I disagree. I have BKR6E plugs for my car and they are defenintly cooper. The NGK Iridim plugs are named like this, NGK BKR6EIX.
Here is a link for some, http://www.zzperformance.com/cobalt_...ts1.php?id=490

 

The problem i am havinh is getting the hub on, its just too tight. I'm going to attept to take it off today and use a scotch bright wheel on a die grider and take the paint off, then i'll heat it up and hopefulley it will go on there.

 

We had a problem slipping it on teh snout because it is meant for a INterchange-able system...and we just slapped the pulley on...But after using some "tools" lol we got it on.... and its running nice

 

Dude you should not have that much problem putting the billetflow pulley on. I watched them put mine on in like 5 minutes. Not including the time it took to remove the supercharger. I did however notice that the 2.9 is really close to rubbing the snout.

 

Finally got that SOB on, had to heat the hub to 450* F and even then it took two trys, what a bitch. But now it will never have to be done again.

 

can we get back to the post pictures of your pulley setup. i want to see them

 

dahahahaha hijacked

 

Seriously.....

 

 

Nice. Glad to hear that you got it on!

 

Are u just running the 2.7" pulley with stock injectors and plugs? If so is there are problem leaning out the engine? And are u running the tensioner too? Setup looks very nice. I'm starting to like the look of the Billet Flow!

 

Yes no iunjectors or anyhting yet. IU live at roughly 6000-7000' above sea level so my boost levels have been very low. Stock i was getting 6.5, 3" pulley i was getting 10, 2.85" pulley i was getting 11.25, and now with the 2.7" i get a touch over 12. I did got to a lower elevation tonight and i was getting 13 before the boost bypass kicked in then it went down to 11. I want to get a A/F gauge so i can see how lean my engine is running before i run the boost bypass mod. Yes I do have a tensioner, got it from the guy on ebay.
