gonna be at 10.5 compression,can I s/c ?

[motorhed66]

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.

[motorhed66]

oh ,its got all the goodies .

[Super T]

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.

[motorhed66]

Thanks guys , Ill ask stu what he thinks also

[Hemi31]

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.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.

[Redfox0099]

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]

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

[Redfox0099]

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

[motorhed66]

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]

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]

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!

[WLYBSB08]

Why not combine Air to Air Intercooling, H2O&Methanol injection and E-85?? :spock: :racing:

[motorhed66]

well looks like I got a vortech...doh.. couldnt pass it up

[elcobra44]

Nice!! :)

[JarZ]

A 392 and a blower... I want a test drive:mrgreen:

[motorhed66]

Im scared to death..I'm out in the deep water..swimming with the sharks ..got alot to learn...Me and Mike are gonna be best buds.Im gonna need alot woodford reserve..

[LouZ]

He's not the only one :))))))

[BAMF]

Stu always seems to help you find a way around your obstacles to spending more money. If you want/need any help or helpful hints on installing the Vortech, let me know.

[motorhed66]

FALSE alarm guys ...I had to pull the plug.Im gonna supercharge, just have to wait a little longer...it was impulsive...sorry.Im lost in a mod bug haze and I was hangin myself out there alittle too far..to be continued.

You will be fine with that compression.
Just make sure you have a good intercooler, and you will be fine.

I run 6-7psi with the CR all the time on pump gas, daily drivers.
