Well, for a while now in the downtime of my R I have acquired alot of parts. For a while I had the boost upgrade crank and alt pulleys. I planned to keep them on until the kamikaze header did not fit. I could not get it modified in time for tuning, so I went back the the 5.5 psi pulleys for now. Here are the results:

220.0 HP, 148 TQ, and still rising at redline.
Granted its a 5.5psi pulley, it only produced 4.5psi boost. (belt stretching issues from new belts)
The dyno chart:

For only 4.5psi boost on a supercharger, I was quite impressed. It gives me hope for the retune under 11psi which will be coming up soon.

Cliffs: 220whp @ 4.5psi JRSC

Its about damn time....

 

I like how you've got increasing power all the way to 8500 rpm!

The set redline is actually around 9,200 rpm, however it is not safe for me to take it that high. Once I have an upgraded valvetrain, we will see the motors limits. At 8,500 rpm the HP spikes upward, but the TQ drops.

 

Any other info on your set-up? What engine management? What size injectors? etc etc ad nauseam

 

j00 know where to go for the valvetrain work

what are your impressions, of before and after the tune?

how's the idle now?

Hondata, I forget what size injectors

 

wow good numbers!

and i say this from one JRSC ITR to another!

 

nice #'s

 

g00t shiet!

Nice. I love that steady even increase in power.

My friends dad just had the JRSC Stage 2 put on his R. Basically, 9psi, Hondata, bigger inj.(cannot remember the flow rate) and DC header(2.25collector). Stock intake, cat and exhaust. He put down 220 to the wheel after tuning.

Now I want one

 

that looks like a great, very useable powerband. You'll have to take me for a spin next month

 

Smooooooooth power is the best power
Good tune Jeff and about time you got that 97 tuned... How many years did you have that JRSC on there?

 

looks good, now you can drive the car

Hondata s200b, RC 440CC injectors, AEM CAI, comptech header (soon to be replaced with kamikaze header w/carsound cat), walbro 255lph fuel pump, and a bunch of stuff I am probably forgetting because I just woke up.

I cant exactly afford valvetrain work right now. That will be some time down the road, and will let you know when I can afford it.

Before the tune the car ran rough. It sounded like I had lumpy cams, sputtered, and gurgled. After the tune the car purred like a kitten, the idle was great, noticably more power, much smoother, and didnt sputter or gurgle at all. It was great! Jeff is one hell of a great tuner.

 

I think boost is somewhat necessary to keep up with the other newer cars in our class that have simply more power out of the box.

I have a set-up spec'd out for a JRSC on my caR, can't wait to start getting the parts together.

 

Nicey nice...

 

i woudln't bother with valve train for supercharger.. no need to rev that high unless you got huge compressor

BAN for boosting a N/A car that is perfect out of the box!



Nice jarb though! I need a dyno pull or two on my new setup too.
