GSR -97

I've decided to supercharge my GSR.

My only mods so far are: CAI, typeR cams, adj cam gears (not installed yet)
(I was originally going to go all motor)

Jackson Racing claims typeR cams will decrease power on a SC GSR by 10whp.
I'm new to the FI world and wondering if I should sell the cams, gears or both and put my stock cams back in.
Do adj cam gears benefit a SC GSR? Do typeR cams?

Anybody else run this setup?
!!Thanks!!

I wouldn't ask JR supercharger questions here. This is primarily a turbo forum.

Good luck. Tom

truly dont supercharge your gsr youl be desapointed
go get a turbo

GSR -97

Thanks for the link....

I may still buy a turbo(not 100% sure yet)

What about my first question applied to a turbo setup instead of a SC then????

R cams / adj gears with turbo ?
I just want to know if I should sell this stuff or if it is worth while to keep with a turbo. I'm hearing different stories. ???

Thanks in advance!

Easy guys. The question is applicable to any kind of forced induction.

The Type R cams aren't going to help you. In a FI application, you want to avoid overlap of the intake & exhaust, which is what hot NA cams provide. The cam gears, on the other hand, could be of use, as they would allow you to get rid of any overlap on the stock cams. You can find forced-induction specific cam grinds - I believe Crower carries them. Higher lift, but no overlap so you don't bleed off your boost that you've worked so hard to create.

Another possibility would be switching to a short ram style intake instead of the cold-air. There are reports that the shorter intake path benefits a forced induction engine more than a cold-air setup. Although if you're not intercooling a jackson racing setup, the cold air may be of more benefit. It's a tradeoff.

But your biggest bolt-on gain with a forced induction system is going to be a cat-back exhaust. 3" diameter is the standard.

Whether you go with a supercharger or turbo, get some decent engine management. Any kind of ECU-tricking, FPR-style management isn't worth the effort, in my opinion. And with accurate fuel/ignition tuning, any setup you choose will be reliable & powerful. Just learn about them all & choose the one that suits your driving requirements.

Well said.

I don't know what some of you guys are smoking, but the jrsc is a great bolt on option for making power. The ITR cams will lose power because of the height and duration of the cam lobes. The roots blower likes to run a long duration cam, with a low profile. Check out Crower's new jrsc grind for a total of 15-20 whp gain.

As for the cam gears, they worked well with my stock GSR cams. I spun the rollers to 200 whp and 149lbs of torque with nothing more than cam gears, 6psi pulley and short ram intake.

This equated to a 14.1 @98mph on street tires (my 1st GSR run )and 7th overall (out of 70) finish at the local autoX track. Some tips for upgrading the boost are bigger injectors, bigger pump and some sort of MAP adjustment components. Or you could go Hondata and bypass the big fuel pump and MAP mod. I think next season we'll see some good numbers from the jrsc camp on both the dyno and the 1320.


cheers!
