Here is a dyno from Comptech once they were finished designing a 10 pound upgrade kit on my GSR for the Jackson racing supercharger.

My B18C1 was internally bone stock. Here's the list of mods I did...

Jackson Supercharger
Comptech 10psi Pulley
Comptech Fuel Pressure Regulator
Walbro Fuel Pump
OEM NSX Injectors
AEM Fuel Rail
Comptech Ice Box
Kamakaze 4-1 Header w/2.5" Outlet
Skunk2 Test Pipe
Tanabe G Power Cat-Back

That's a nice looking dyno chart. Very straight. Have you taken it to the track yet?

My best e/t was 13.6 @ 104mph with a full interior. Car weighed 2680lbs. without driver.

New project is a '91 Civic DX hatch that weighed in at 1940lbs. stock with just the rear seats removed.

Man, that's a nice car! Clean! Total sleeper :eek:

So what kind of tuning device did you use to tune the car? The numbers are very impressive, and so is your 1/4mile.
Do you have any traction problems? What 60' times did you acheive?

I'm planning to supercharge my GSR, but I know the JRSC folks are having a lot of problems with heat-soak which caused a lot of detonation problems. So do you have any problems with heat-soaking your motor running 10lbs?

Thanks for sharing! :)

Comptech did all the tuning. They did 32 dyno runs to design and tune the upgrade kit.

Traction problems? Yes, a lot. Driving around on 17's was not pretty. I usually drove on my Nitto drag radials which held most of the power in first gear.

I had no detonation problems... even in 100 degree summer weather. I did on the other hand suck 2 bolts that hold the intake manifold to the blower and destroyed 2 superchargers altogether. It turned out to be a defective Jackson intake manifold design.

If you're not braking parts...

That nice! Hmm, if Comptech did the tuning for you, then you must have a chip or a black box in your car that you did not know of. It'll be nice to find out what it is and add that to your mod list :cool:

BTW, what kind of wheels are those?

your integra looks really nice man! but for a supercharged GSR running 10psi.....225hp is nothing, i know kids with all motor engines that make just as much power......i dunno, just doesnt seem like much power for a 10psi supercharged motor......nice 1/4 mile time though!

Yeah I have never been impressed with the supercharger on a honda, but it seems to be working well for you.

Thanks for the compliments guys, I appreciate them.

To answer a few questions...

The ECU was left bone stock, but Comptech did bypass a sensor or two going to the intake manifold to fool the ECU when it was under certain boost. It worked great.

The rear tie bar is actually Comptech's rear 22mm swaybar/tie bar combo. They designed that on my car and I ended up with the prototype... for free! The guys at Comptech are awesome.

The HONDA emblem is off a 91 Honda Accord. The front and rear "H" are off an S2000.

The NSX injectors Comptech installed flow around 290cc. I was told these OEM units flow just as well as RC. You don't need anything else, they are plug and play.

I must say, I did expect more than 229hp with 10psi... but the car sure felt strong. Not like a turbo, where the surge of power hits you all at once. My car pulled strong from 2500rpm all the way to fuel cut-off at 8200. Going north on Interstate 5 one quiet evening I almost redlined 5th gear... the speedo tach was buried and still going. It was scary as hell.

Can't wait to drop a B20/VTEC in my '91 hatch with a DRAG turbo kit. There are a few Viper owners in Sacramento I want to embarrass.

Comptech told me that 10 pounds on a stock engine was high enough.

The supercharger maxs out around 13 pounds, but I didn't want to damage anything internal. It was my daily driver/V8 killer.
