Stillen air to air conversion fabrication thread

EVOHUNTER · 07-27-2015, 09:31 AM

I have a impeller, I have a full cog set up.

I have a custom 2.43" pulley for the 7 Rib serp side.

this ill be doing next year with a return fuel system and 850cc injectors.

This year I have the stillen 2.75" pulley on the serp side.

And the I put on the 2.75" pulley on the blower. has anyone does this setup yet?

This should be around 10 psi I think?

Someone chime in for me.

EVOHUNTER · 07-27-2015, 10:31 AM

Im tying to figure out what kind of boost im gonna see.

Cranks is 5.75"

Both pulleys on the jack shaft are 2.75" and the blower pulley is 2.75"

I can only find a calculator for a impeller rpm.

Where did you get the cog set up and pulleys from?

Sweet as, are you expecting any gains from the conversion alone after tune? or just all prep before the big mods

A lot of people forget about the spacer behind the pulleys on the blower.

This causes the belt to be slightly crossed. My friend has the same setup in his 350hr hes running 16 psi, on the V3 blower. He hasn't had any problems as of yet!

No headers, oem.

JWillis72 · 07-27-2015, 12:26 PM

Do you know what size that spacer needs to be?

EVOHUNTER · 07-27-2015, 01:16 PM

Honestly, I don't.

I used a standard washer that fit over the supercharger shaft, and ground it down to the size I needed. I'm going to post a full DIY for the cog setup on the V3.

EVOHUNTER · 07-27-2015, 04:59 PM

Im trying to find a idler pulley with a flange on the edges, but all I can find is a 3"..

I think it will be to big.

im gonna ditch the idler with no flanges, I feel the flanges will only help with keeping the belt straight.

I need one like this! but not 3.5"s lol

JTran had mine made. Custom 2.5" idler. It worked perfect with the 34T-30T cogs on my HR. I think they kept the drawings for it in case someone else needed one. They pressed in the same bearings the stock Stillen idler used. Give them a call, they might still have mine sitting up there. They are open Tuesday-Saturday. Amber should remember the pulley, but it was a while back.

I think my car was the only one they setup that way. So Amber or Johnny will be the best people to talk to about it. The others may not remember it.
