Im gonna have an inertia 392 and it will be at 10.5 compression..Can I still supercharge in the future if Id like? 6lbs, more? what say you supercharger gods .

Yes, you can SC a motor with 10.5 or higher CR, provided you have upgraded the internals (pistons, rods...) to handle the power.

oh ,its got all the goodies .

I don't know if I'd go any higher than like 8psi even on high end internals.... 10.5 is getting up there for a blown motor.

Thanks guys , Ill ask stu what he thinks also

Depends on the pistons Todd.It also depends on the overall compression.What you want to do is not go over 17:1 overall for a street motor.
I am pushing 10-12 psi on 10.5 compression....but I know my pistons are strong enough to take it.

Depends also if the motor is built for boost or for N/A

I have 10.5 compression but my forged bottom end is set up light to rev faster...I wouldn't put boost on my Current short block.

**motorhed66** · 08-20-2008, 07:15 PM

It is set up light, red , you just answered my question I think...no supercharger for ole Kyle E...

**Redfox0099** · 08-20-2008, 07:16 PM

Hey if your motor isn't finisnhed then...well, if you have the pistons already made then it is too late.

**motorhed66** · 08-20-2008, 07:25 PM

engine is complete...Im not bummed . Im sure what this thing is gonna be laying down will be enough for me. its a DD so that should be plenty.

Motorhead, why not just go with a nice nitrous set up for the track and run 100 octane unleaded only at the track. A lot cheaper too.

**motorhed66** · 08-21-2008, 11:29 AM

Really just asking if I could if I wanted to. With my work week ,trips to the track would be far and few between.So, it would be a bragging rights kind of deal and how important is that? I surely didnt NEED a high reving 392 stroker either I supose...anyways ...if the blower bug gets me ..I want to know what Im up against

**motorhed66** · 08-21-2008, 12:23 PM

hahaha Doh! Stu says my ringlands are at about .280 and if I really wanted too I could do big chamber heads and different gaskets to bring the compression down and go 8-9lbs boost if I wanted in the future...ya gotta love that stu guy..he finds ways for you to blow 10 grand right off the top of his head!
