Dyno'ed my single turbo today.
 

Made 460rwhp/353rwtq on a dynojet today @ 20psi. Car didn't seem to hold 20psi to redline though, bled off to about 17-18.

Wish I would of broke 500! Hah.

well why dont you tell us what turbo it was and mods you have

Rx7store Stage 3/Race Port
Gotham Racing GR63 kit
550cc/1600cc
Dual Walbros
Trust FMIC
Koyo
HKS Twin-Power
etc, etc.

video? sound clips? :)

what's your boost curve per rpm like?

Damn, those are some pretty good #s, congrats :). I am hitting the dyno myself soon and hope to make it up towards that level!

Thanks guys, hopefully I can either figure out this boost problem, or just upgrade to a different turbo sometime soon.

Here's the incar video.. more to come soon (uploading them now):

good numbers...

sweet setup bro

Congrats bro :)

:icon_tup:

thats good numbers, goodluck in getting 500hp

Awesome. How high are you injector duties at that boost level with you current setup? Also, who tuned it or did you tune it yourself?

Is that a 63mm turbo? What's the a/r?

when does she get started? 3k-4k?

I could tell you if I would have remembered to bring my laptop so I could log some stuff hah. And rx7store tuned it, but I think I'm gonna give tuning a try myself, I really want to learn.

It's a 63mm turbo, but gotham racing wont tell me what the a/r is so I don't really know.

20psi by about 3800-4000rpms, not too bad.




and thanks to everyone else for the kind words :)

here's a vid of the run, outside of the car: http://videos.streetfire.net/video/C...F386AFD68E.htm

nice man..

Good number. If boost is falling off up top then you are losing some HP. We figured you were closer to 480HP based off our Mustang dyno numbers, but that was holding 20 lbs.

Jason

pump gas or race?

110 leaded

Any update? Did you get your problems sorted out?

Also, what is spool time like at 15ish psi? I remember helping to get the first kits together at the shop but unfortunately never got to drive a car with the GR63 installed.

I'm considering running this with the dual BB option, looking for 450 rwhp on pump gas/water inj and good responsive spool from 3500 and up.

really...that's some shit. When you go single, you are going to wish you did from day one, haha!

Yeah, that is what ccarlisi keeps telling me.

I dunno man, if I convert these BNRs to sequential, that is a powerband that is hard to beat......400-425 rwhp with full boost near 3k rpms?

yes, that would be sick...IMO, these cars need to be either BB single or seq.

I would get full boost (20psi) around 4500-5000rpms.. and then the motor let go at about 5000 miles. Go figure!
