How's the pistons, rods, bearings, valves, etc?

Sabre2 · 01-12-2013, 11:41 AM

I would like to know more about the bearing failure being due to the Stillen underdrive pulley. I was under the impression that the Pulley's from Stillen & NST were safe.

You'll have to do a search or two on the subject. theres a few threads somewhere about them.

just not worth it in my opinion.

Thanks for the responses. I did a search previously and it seemed opinions were all over the board. But yea, not worth the risk.

He's talking about the JUN Exhaust cams.

esfourteen · 01-14-2013, 11:27 AM

There was no reason for any bearing failure so soon after install with 500whp and a safe tune, and oil temps were never over 220. Regardless I can't prove the stillen pulley did anything nor am I going to attempt to, there are other reasons not to use it (it galvanizes and bonds itself to your crank over time), use it at your own risk.

From what I read about the Jun exhaust cams, the profile was not designed for boosted applications, I would be interested in seeing a before and after on the same car with boost though.

I have some disappointing news, the machine shop never decked the block (they try to avoid it if possible apparently) and one of the techs discovered a small gouge in the surface of the block at the very edge of the cylinder and the risk for head gasket failure is too high so the block is going back to the machine shop. They will have to disassemble the block, deck it, and reassemble.

The ETA is 2 weeks from them, which is pushing my build completion into mid February

I ended up purchasing new @ $1600.

What do you know and plan on?

Thanks.

Coop

the VVEL controllers can be reused, this has been proven, I'll be reusing mine.

Exactly. Better they "do it right", now.
