Well here we are. A dyno sheet as promised. Dave said that the dyno has very recently been calibrated and rebuilt, so it should be accurate.

One run is 12PSI, one 19 and the final is 22PSI.

I am happy with the numbers.

Maybe not. I cannot get it to upload. I will try later.

My 22PSI run yeilded 457HP and 376 torque.

 

hmmmm, cant wait to see the dyno sheet so we can have a look at the reponse of the thing

that said, how is the reponse?

 

Not bad
what did you yield on the the other 2 boost setting s

 

Was that with a safe tune, cause that sounds a little low of the power numbers that I was thinking we would be seeing with the kit. I was hoping too see over 500 at the wheels around 20 psi...

Well looks like I will have to wait till I get it one the dyno to see

That was a good mid 11.5:1 AFR under boost run.

500 would be achievable maybe at 28-30PSI?

We compared similiar files on the dyno computer looking at comperable boost runs with T78s and GT35/40's from other peoples cars and the number make sense.

I think that there may be some inflated dyno sheets running around out there??

Still trying to get the sheet up and keep getting a database error. It's only a 36kbs file.

I'd like to upload my timing map too as soon as I can.

 

12PSI run, 367RWP and 296 torque.

19PSI run, 404RWHP and 335 torque.

See the pattern? The numbers make sense.

 

I'd LOVE to have your HP #'s. hehe.

I bet that thing pulls HARD.

 

Any hints on how to get this motherf#$%er to load?

 

how come you did not turn it up to 26 or so?

 

Because I am a sissy.

Actually, I was a little concerned of my injector duty cycles approaching 90. I was seeing maximum duties in the 85 range at 22. I am running 4 1000cc injectors.

Just trying to play it safe.

And, my Profec B was cranked the whole way. I could have adjusted the sharpness, but then I would start to have spiking issues.

Man, 450 is plenty don't you think?

 

Plenty is when your tires don't stop spinning

 

How much boost until the e-shaft bends or other catastrophic events occur in the engine?

 

Great numbers... I would have guessed a big HP gain from the 12psi to 19psi pull. Either way looks great. Do you have a list of mods?

 

 

That does seem a hair on the low side but not way out of line, at 15% loss thats around 525hp not too bad, I don't doubt some runs are inflated. KD always seems to be lower than the others, be it dyno honesty or whatever, still in a avarage weight RX7 it's pretty close to a 5 to 1 hp to weight ratio nice for a street machine self tuned by it's owner.

 

nice #'s Zach, glad to hear your car is back on the road again... im sure a little more boost and another confident day on the dyno you could get it up to 500rwhp

BTW: what octane were you running? and did you tune it yourself?

 

Steve, no need for an ignition amp. I am running a set of M&W coils directly from the R500 CDI box. The stock ignition system is on the shelf. I have a simple stand-alone RPM switch that puts it into high power at 3000RPMs.,(accomplished by grounding one of the leads).There is absolutely no ignition breakup. http://www.autronic.com/page_files/direct_fire_cdi.htm

 

100 Octane. I have been running it for a while to be safe.

 

Yes, with some help from Enzo's base map.

The air fuels are very easy to tune on the ECU I have. It pretty much tunes the fuel automatically.

I plan to post the timing map as soon as the forum allows. I have it scanned in as a image file also.

 

Great, another Autronic user Why did you go Delphi 1000's and not Bosch 1600's ?

 

Based on your 12psi run you should be over 460rwhp @ 19psi ??? Does it go real rich or pull out lots of timing ?

Oh and 490+ at 22psi based on the 12psi run. Were you boys doing some major mixture changes or playing with timing ? Cause some of the differences in power (both up and down) are not corresponding with the changes in boost pressure. What power is that turbo good for on a 13B rotary ?

 

cool Zach not that many people here in the states run that ecu but its a great unit i hear. Did you use the "Autotune" feature? where it tunes itself? Im sure a couple of more dyno runs and a little more experience you can get those power #'s up higher!

again good to see your car on road especially with over 400rwhp!

 

also wanted to say thanks for the numbers zach

 

use photoisland

then get a external URL (u'll see the option after uploading) and post it here with
the {img} {/img} but use --> [ brackets instead

 

Thanks for posting the numbers, very soon we should start seeing a lot more dyno numbers and this is the first step for the gt40r and knowing what it can do. I can't wait to see what numbers my car will get
