anyone running 9-10 psi on stock internals?

[LOwrestling2001]

Who here is running a JRSC at 9-10 psi on stock block? just wondering. i'm currently running an endyn stepper (but my boost reads 10 psi max) with my hondata making 230 whp. just wondering how safe it is. oh also heehee while i'm at it here's the dyno.

Nice! I am. . .I am using Jim's 9psi stepper pulley on a stock GSR block. Works and FITS muuuuuch better than the Endyn one, in my opinion.

What's your full setup?

I hope to hit atleast 230 whp at my next dyno session. [img]graemlins/thumbs_up.gif[/img]

I'm using a CRV crank pulley and see 12psi on the boost gauge. All stock block and head.

I figure I've got 240-250whp.

I was using the Endyn stepper pulley to get 10psi on my boost gauge. At 6psi i dyno'd 210.3whp and 156wtq. At 10psi i ended up with 246whp, and 184wtq. All stock block, no electronics or gizmo's, and still using an FMU.

It all worked great for me.

I'm at about 9.5 psi according to the guage and running hondata 2b w/dsm 450cc injectors. I'm running the base program right now, and haven't had a chance to tune it yet. The problem is that it's running hot right now. I've actually lost power the last few days because of the 90-98 degree weather outside. Hopefully when I tune it next week, I won't have any problems. It sure runs well in the AM though, before the day gets too hot.

If tuning doesn't fix my problems, I'm going back to 6psi and a small shot of nitrous.

The jrsc just likes to run hot.

I am running 10psi on Endyn stepper pulley w/ Hondata 3b. The Hondata is untuned, but the car runs very well. Some might think I'm aiming high, but Im hoping to get it tuned and have about 250-260whp. At 6psi it did well w/ just a VAFC and the Hondata feels so much better so I dont' feel it is unrealistic. Anyway internals are stock and odometer reads 100k as of this week.

i'm currently running:
ITR cams, portflow valvetrain, AEM short ram (hopefully i'll find a 3 inch intake to replace it any suggestions?). i have a JDM DC 4-1 header (hopefully to be replacd with a kamikaze soon). also running a 60 mm RSR old skoo quiet exhaust with a 2.5 cat. with hondata 2b and RC 440 injectors. i'm running the endyn stepper it reads 10 psi so i guess thats how much i'm boosting. i'm thinking i might be able to squeeze out maybe 10 more hp out of the kamikaze and bigger exhaust and intake piping hopefully might help. but for now this power is plenty to make my new kumho 712s break traction from a roll in 1st still. yea hondata makes the transition into boost so much smoother. my endyn stepper went on fine...with some loctite and impact gun.
