Wondering if anyone has had the carbonite coating done to any of their pulleys yet? The LSA blower guys are doing this and was wondering if any centri guys have done it ?

Josh@AandASuperchargers

We have not tried it yet, but some guys swear by it and some guys say it chews the belts up faster.

Guess I'm gonna be a guinea pig and try it, I don't mind changing belts every season so if they will last at least a season for me then I think it will be worth it.

I spoke with Andy a while back and my local shop is a big supporter/installer of A&A kits. I was working on a bigger build, motor included, on my 08 z06. Current it is full bolt-ons with slightly bumped compression on MAST 305 heads (65cc chambers) at about 11.6 or 11.65:1 CR. I really want to do the blower, with meth obviously. Is is feasible to run that setup on a good tune for a while? It's a weekender car, not always beat to hell, but I do let her eat when I'm out. Shop owner has an A&A t-trim blower z06, but no head mill. Would going with a slightly larger pulley than normal be the way to go? Want to get thoughts on this before I do it.

Josh@AandASuperchargers

It's totally doable, but you have a much smaller tuning window with such high compression. You will for sure want more octane whether it's from meth or E85, or both. Low boost, high octane, and great tuning will be the key to making it successful.

What about cam overlap. Unfortunately my current setup wasn't with the blower in mind. I think, using a cam calculator utility that my cam shows about 22* of overlap. Makes great power now but I'm not sure what the bleed off of boost will be. Is there a threshold you recommend or suggest? I will be pretty close to a cam job just to do the crank pinning so it isn't the end of the world to change it, but I'd rather not if I could avoid it.

Josh@AandASuperchargers

If you are happy with the current drivability of the cam, then don't change it. If it runs good n/a it will run great with boost. I've done MS4 cam on 109 LSA in stock bottom end LS6 and added A&A kit later and it was awesome. Don't let the internet scare you into a smaller cam.

Hey Josh,

3.4" is OK with the si, it's not overspinning? I'm at 3.6" si, and would like to drop to 3.4 (I'm in CA so I want to keep the CARB-approved si). Going to go E85 and mild cam as well. Because 666 RWHP doesn't get me in enough trouble.

Josh@AandASuperchargers

Here is the Vortech calculator

Use 7.25" for the balancer. You can run a 3.4" for about 2 more psi. If you add cam and pulley you will also need a external fuel system. We offer the single pump rated to 750rwhp and the twin pump rated to over 1,000 rwhp on gasoline.

I noticed a few drops of red oil on the bov a while back. I cleaned it off and continued to drive the car. Never happened again. Do you think the oil was maybe just filled too high?

Josh@AandASuperchargers

Maybe, but you might want to pull the silicone hose down from blower outlet and look inside to make sure it's not a puddle of pink V3 oil in there. Like if the blower started leaking internally and was blowing thru the outlet. Or a puddle of engine oil if you are getting excessive oil vapor pulled into the air filter from the breather hose.

LSX228R

Thanks for the fast reply. I check the oil level and its fine. I'll have to put the car on a lift one day to check the hose. Hopefully its nothing.

Did I miss it in the thread, can't find in the instructions what are the torque specs for the bracket to block and bolts to supercharger are. Is there a torque spec sheet from A&A? If not, 37ft/lbs suffice for bracket to block and the studs going through the bracket,spacer to SC?

Josh@AandASuperchargers

We just make them "wrench tight", or 3/8" hand ratchet "tight"
It doesn't take much to keep them tight enough.
And we only use a dab of red loctite on the SC pulley bolt.

Is there any upgraded fan options for the radiators that come in your Z06 kits?

Josh@AandASuperchargers

D3 Performance has a nice fan upgrade for C6s. You have to do some trimming and clearance, but you can get them to fit with SC kit.

Josh,

I cleaned and re-oiled the BOV piston with gun oil. I adjusted the BOV cap to cover just the "O" ring. I believe that is where A&A had it, but want to make sure. I know maximum adjustment is at the indicator ring. Is that the correct adjustment for my set up?

That should be fine, it's not critical.

As my kit is being installed, discussion with the tuner has uncovered that early MY z06's (mine is an 08) don't support injectors or MAF flow enough for the blower kit on top of my current N/A setup. This seems strange since MANY are running around with blower kits on early Z06's. The suggestion was to use 72lb injectors and account for additional fueling with the methanol, as opposed to using the included 92lb injectors (lb flow taken at 58 psi fuel pressure). Any recommendations on using larger injectors with these early MY Z06's or if this can be bypassed somehow and what to do about the MAF?

Your tuner is an idiot, find a new one.
