High Compression boost?

High guys I have a rebuilt VQ35de non revup motor and currently I have 11:1 compression pistons in it.

What are your thoughts on boosting with this setup?

JWT C2 cams/shim/springs
Wiseco 11:1 pistons
Eagle Rods
HR Gasket Mod
ACL Engine Bearings
Z1 Viton Valve Seals
ARP L19 Head and Main Studs
Balanced/Bored/Honed block
Z1 Shorty Headers
Fast Intentions Test Pipes
Borla True Dual 3" exhaust
Aluminum Driveshaft upgrade
Z1 Oil Cooler
Mishimoto rad with dual 10 blade fans
Walbro 255
Bosch 600cc Injectors

I was looking to grab a supercharger to see how she does with a little boost. Do you think my compression ratio is too high or will she be fine with some FI in her?

well ideally a low compression ratio is better. less force on all of your internals. you can still add a supercharger on your car but just try to keep the boost PSI low.

it will be a screamer. just make certain that your tuner is very skilled and on point. the low compression ratio of a forced induction build is a safety window. you will have a very thin line between the perfect tune and horrible detonation. use lots of fuel..meth may be a good idea as well to drop the intake temps.

shouldn't need but maybe 5psi to push serious numbers with 11:1

I was thinking maybe a thicker head gasket as well

depending on the thickness, that will only drop you .2 or so..still 10.9 is going to be slightly better than 11:1 though... just make sure to use ARP studs on the heads.
