which vendor sells the bigger idler pulley, i purchased the sfphq 2.8 and a 3.0 and il need the idler pulley for the 2.8, i did a search but didnt come up with a certain vendor


thanks

 

I have them

 

what size is your idler pulley? I heard that if you put on a 3 inch one you have to grind down the stock tensioner and spray paint it.

 

Nah Billetflow machines the idler pulley and no grinding necessary and they are 3". Billetflow is the shizznit and the pullies are pure quality. Waiting on my order to get to Wisconsin Doug

 

another vote for billetflow.

 

Can you tell me what the link is for the idler pulley?

 

Same. With a 2.8" pulley i will need the 3.0" idler pulley correct? Link Please.

 

Can we see pics? I have physically done my own and i can tell you with GOD as my witness, there is NO WAY you can fit a 3" pulley w/o modifying the braket or w/o having belt alignment issues.

 

Maybe Doug from Billetflow can address this?

 

That would be cool! Maybe i need glasses in my old age Or micrometer is out of adjustment???

 

What size is the intense idler pulley?

 

3" standard ansi groove pulley

 

Just checked and got some info, the Billetflow idler is 76mm (3.04") and apparently a bunch of Redline guys are using it with no grinding and no issues. I am actually using the idler as a temp solution and waiting for an adjustable tensioner bracket.

 

Pics of it sitting on an unmodofied bracket and how much?

 

Guys are actually running it in their cars. Price retail I believe is about$25.

 

I understand that, i just would like to see how it is done since there is no info on the website.

 

its a big secret. Mine should be here tomorrow. i'll steal the ex gf's camera and try to get some pics.

Dan

 

I spoke with doug and he said that it is 70mm.

 

Let me know if you can install that puppy and not have to grind anything.

 

Finally, the truth! Thank you !!!!!! I knew it couldn't have been a 3" pulley

70mm = 2.76"

Stock = 2.5"

 

Anyone have pics of where you have to grind on the idler?

 

Does the "2.76" inch idler pulley from billetflow make the belt slip with a 2.8 inch pulley? Or is it enough to stop the slip?

 

3.31"- 2.80" = .510"

The pulley is .250" bigger so i would say ?????

 

iirc you can drop to a 3" without slip. That is .31" drop. As long as 3.31-(your pulley size)-(the size in inches your idler is bigger....250" in this case)= less than .310 you should be fine.

So you should be able to go to a 2.7 with probably no slip a 2.7 yields .36. The BF pulleys are sandblasted and have proper v groove geometry so you shouldnt have any slip problems at 2.7...also any smaller and you need to machine the blower snout.

 

Could you use the idler pulley with the tensioner at the same time? (stupid question, my brain seems to think you can though, I mean why not?) Because I would like to do the cheap idler pulley for like 30 bucks but if the belt starts slipping, I would use the tensioner in conjunction with the idler pulley.
