Had the car dyno tuned by Wayne aka Waynespeed, he is the dist. for Wolf computers and has many reliable high powered tunes to his credit.

We tuned it back on the 9th, but I just got the print out last night. Last night driving to get the printout I realized for the first time my factory tach falls off at higher RPM, I know at about 4200 on the tach the wolf was reading about 400-500 rpm LOWER.
Picking up the dyno sheets confirmed what I thought- originally we revved the car to what we thought was 7200RPM, turns out it was only 6150 RPM!

My rear alighment is way off right now and we are re-doing my pipes from the REV II y-pipe back to 2.5" from 2.25" so when thats done its back to the dyno to confirm the tune is clean to a real 7200RPM and with the exaust changes and the alighment not acting against the dyno.

Here are the 2 graphs, one does not show torque or RPM just peak HP but thats the 4th gear pull.


The 4th gear pull is the blue line, showing a peak of 280hp at what was 6153RPM. Not bad considering the small turbo and the fact we had 1000 rpm to go.

Motor is a street port S5TII turbo is a garrett t04b. A turbo change is already running through my head, I just wanted to get the swap done and sorted out first.

The second graph is a 5th gear pull so I guess that one wont count but it does show the engine RPM.

Some picts of getting it on the dyno and the graphs

That Rx-7 kid

nice 1993 Rx-7 convertible Rob! When did they start making those? hahah someone made a mistake there.

I think at just about midnight the last thing they do is bother filling in that information, lol

it was printed out in the afternoon, had to go back for the printout as the printer was out of ink.

I don't know which T04B you used or at what boost, but 280 sounds low for the stock turbo. did you pressure test for boost leaks?

its only 14lbs, and I still had 1000 RPM to go.
Re-testing in a week or so

went back to the dyno tonight to tune the Wolf V500.
Wayne from Waynespeed worked his magic and played with the setting and we utilized the built in boost controller and even a shift light output from the Wolf. The wolf offers so much most people, including myself, do not realize what it can do when the right person is tuning it.

Big thanks to Roan, Steve, Marley, and anyone else im leaving out.
Im happy with the magic number of 400hp and about 285 ft lbs torque.
I have more graphs but I have to scan them, and its late and I need to go to sleep!

Im going to cross post this to my previous dyno thread and my other project thread.

Nice Pull, Rob. Am I reading this right, that you pushed to 8000rpm's on the 400+ pull? I'm only pushing to 7600, due to my fear of S4 stationary gears giving out above that. Also (and this isn't a cut to you, I'm genuinely curious), I wonder why my car makes more torque with less horsepower? It's even more perplexing since a higher compression S5 motor has more torque to begin with anyway. Any thoughts?

I have no idea about the torque, honestly I have never paid that much attention to other set ups to compare to, I was just happy to have the car perform the way it did for such a "small" turbo. Im learning as I go.

My car has all S6 rotating assembly, we set the rev limiter at 8000 but the shift light at 7000, I will rarely ever bring it to rev limiter.
