lsx_production

I know you can on a PD type SC with swapping pullies but that seems to get expensive when you start with the tuning process. I am referring to more of the procharger type. I want to get a procharger for stock ls motor and then either build that one up or move to a 4.8 and throw some low CR pitons and really turn up the SC if that is possible.

this brings me to my next question thats kind of unrelated. Should i Build up a stock lsx for boost or find a 4.8 or 5.3 for boost? I think the extra weight weight will throw off the balance of the car since it will be a car to take on the track. any input would be great. thanks!

Blow-off valve should allow you to control boost.

some people run wastegates over a bov. then use a boost controller

Easiest way is just to pulley it accordingly.

It doesnt get expensive unless you have a fetish for changing lots of pulleys

so procharger offers pulley options for their SC's?

Wastegated and blow off valve and controler they are two different things

Of course, as does every single supercharger manufacturer and tuners

run a BOV for basic back pressure bleed off...engine vacuum will open the valve when the throttle is shut.

then run a wastegate to control boost....
either use springs (simple/mechanical) or use one that has pressure lines above and below the dome and use a boost controller(mechanical/electrical/complex)

there are several simplified boost control kits as well for easy dial in boost..
