JRSC with PNP and/or bored TB
Can you get significant gains with either/both of these mods on a supercharged engine (6psi)?
Oh, and nobody tell me to go turbo, this is about SC

Re: JRSC with PNP and/or bored TB (LuckyNuts)
I go by dynos and have not seen anything yet. Its like the LHT intercooler, you know its a great idea but who has the dyno's to show that good results can be gained from the money and time spent to do the work!

I'm familiar with an aftermarket TB on a SOHC jrsc setup, and it gained at least 6-8 whp throughout the powerband,m from 2000-7500 rpm.
I'll be installing my setup next week, and also installing a bored TB on my b16/GSR head/jrsc/ITR tranny setup. I expect to see near 10whp from the TB alone.
As for PnP, focus on expanding the exhaust side of things, as they can use the most work. Just clean up the casting burrs and lines on the intake side, and I expect you to see another few whp along the whole powerband again.

Re: (hypa)
I have seen more gains with the thottle body , I have many ported heads from some "Big" named companys and they have done almost nothing.I am now running a bone stock Type R head.
I have seen good gains from porting the "S" tube too.

Re: (sporkcrx)
The "S" tube is the piece between the Intake on the supercharger and the Thottle body. It is a very shory piece on the B motor and a long "S" like tube on the LS and the SOHC motors.
