worth it ? A guy wana sell me a JRSC for 1500 USD . worth it ? i mean for my GSR Engine. if worth , how many hp i can gain from SC . if not. how much that SC worth ? thx for reply .

That's a good price if it's in good condition. On your GSR with the stock 6psi it provides, expect some healthy torque and hp gains throughout the entire rpm range. I'd say about 50hp.

thx for reply . another question. with JRSC can i go none intercooler setting or not ? (that guy is doing none intercooler setting now.) do i need a boost controler and boost gage ? can i go higher psi if i change the pully ? how much hp i can expect then ,and how much psi i can do on my stock internal safely ? thx for reply . (may be some grammer mistake . sorry for that .)

eh i dont think you have/need an intercooler for a jackson racing.

you dont need either the boost controller or the boost gauge. Unless you just want to see the needle stick at 6 psi...fun stuff...

You can change the pully and get more boost yes....but i doubt itll get high enough to need better internals (11-12 psi max)

A pulley can bump it up to about 9 psi, and no you won't need new internals for that. You will need new fuel injectors and either an FMU or Apexi VAFC. Intercoolers are for turbos, aftercoolers are for superchargers.

thx for reply . if a pully can bump it up to 9psi. and i get new injectors with VAFC. how many whp i can
expect ? how much for change a pully ? and also, that JRSC has been used for around 2 yrs. (with 9 psi daily) .it should still works good or ? usually a JRSC will last by 3-4 yrs or what ? thx.
