jrsc intercooler
OP you do realize there is a intercooler made for the JRSC from LHT performance! it works very well! iv had my experience with it made 285WHP on 12psi but you still get heat soak from it after a few pulls. I would go with a centrifugal blower like a pro charger but there rare to come by unless you buy a tuner kit new. Im currently using this pro charger kit and it blows away the JRSC with half the boost level. The crafts work supercharger is a good sc as well it will out perform the JRSC all day.

I think whats even more impressive is i made 275 WHP on only 6psi on the same motor using a ATI Pro charger instead of the JRSC.
Heres a pic of how the LHT intercooler manifold looks like installed.

If you get clever with fabrication you could run an fmic with a jrsc.
you could flip the supercharger 180* so that the outlet points towards the firewall, build an insanely complicated intake manifold and run normal piping.
Or you could make brackets to mount the supercharger under the intake manifold, run it with the outlet on top and then run piping.
if you're confused looke at the ford 3.8l super coupe that uses the eaton m90, they run an outlet hat that plumbs into piping for an fmic setup.
th best method is to ditch the jrsc style mounting system entirely. a lot of b and d series guys have had good luck with the following method.
buy an Eaton m90 and flip the drive gear and snout
Mount in place of ac compressor, the OEM tensioner system allows for good belt wrap
then they run piping to a fmic and the intake manifold just like your normal turbo setup.

Maintenance is just cruel with the JRSC! with all the custom fabrication needed to do what wantboost mentioned its probably gonna be a head ache, even how it sits maintenance on the belts that slip and leaks is enough of a headache let alone it being hidden under the manifold ect. its been covered over and over in the jrsc build thread. Only real tested solution is the LHT manifold and or meth injection. Or get a centrifugal sc like the pro charger or crafts work blower. with the cost over around 1400 for the LHT kit id sell the jrsc and save that $1400 and buy a centrifugal sc kit easiest and most available is the crafts work! someone pulled out 340+ hp from a bone stock gsr on 14psi.
I am going to cool down my beer on the kitchen counter and move it in front of a fan.
Then I will drink the beer slowly but swallow very quickly so the beer will cool down as it enters my stomach.
Report:
- Beer drank normally still feels like warm beer
- Putting beer in front of a fan made me feel cooler if I put my face in front of the fan
- Beer gulped down quickly only got me drunk quicker, but still warm inside my stomach.
Beer before drinking = 73 deg F
Beer after drinking = 98 deg F (has been compressed into urine)
Conclusion:
- Beer did not get colder
