Latest Chickenwafer Dyno Runs, WTF Torque??

Postby chickenwafer » Sat Aug 29, 2009 9:14

So I hit up MAC today to do some self tuning and dial in my tune. I didn't want anything too special but admittedly I was shooting for 350ish rwhp.

First off, I don't want hear any shit or crying about how this is a DynoJet, or how anyone feels about MAC's numbers. I want to clear the air- back in Phoenix I dyno'ed on a DynaPac and made 302-rwhp @ 9psi, and I made 301rwhp at the same boost on a Mustang Dyno.

Well today at MAC on my FIRST run I made 301-rwhp @9.5psi. Slightly more boost to accommodate the altitude difference and I made nearly the same power as I did in Phoenix on a Mustang Dyno which everyone seems to except as the Measuring Stick.

So with that out of the way...

My boost controller was a BITCH. I would try dialing up more PSI but the duty cycle settings were causing weird issues, along with some hopping as the turbo huffed.

I was shooting for 16psi eventually but with my solenoids duty cycles MAXED out I was still only hitting 13.8 max psi. So I wasn't able to run the boost I want and thus never hit 350rwhp...

But I digress. I'm still happy because I made a freaking insane amount of torque:

First run at about 10.5psi:

Made 317rwhp and 287 ft-lbs of torque. After a new timing map went in torque shot WAY up. But It wasn't done yet.

After messing with the BC as much as possible I just sad fuck it and went for a run at nearly 100% duty cycle:

Image

Ended up with a ridiculous (for a rotary) 330-rwhp and 326 ft-lbs of torque @13.5psi!!!! Torque was just NUTTY!! I couldn't believe it. The break-up in the line plot is from wheel spin on the rollers (!!)

I was also running pig rich, pulling 10.8 AFRs thru the range since I added a new Methonal cocktail to my injection tank that was drastically dropping my Air fuel ratio. I ran out of dyno time as a 900-some rwhp twin turbo Cobra was waiting...so I couldn't retune.

I will be back, but I need to figure out this boost control issue...

That's sweet dude. cool to see torque up there and the potential our cars have.

I expect a ride one day since I'm back in the USA. You will be at the Birthday Bash right?

I maybe, September is chalked full of stuff to do haha.

I want to ride in an NA RX-8 I've gotten too used to my car LOL.

I have to admit after tuning it today when boost comes on it literally feels like someone has their foot on my chest and then just plants me. it's awesome

If you're looking for company, let me know when you go back down.

I may have seen you. You were turning out onto Parker Road at about 2:05 or so with a white RX-8 right behind you? If so, I was southbound- in a Saturn VUE.

over 300 rwtq on an 8 is freakin insane! I need to quite being a whimp and convince my wife that going FI is an investment... LOL!

Seriously though, CONGRATS. Wish I could have been there to see it.

Thanks guys.

It's also official I made the highest dyno-proven rear-wheel torque on a Renesis EVER!!!

For those who don't know, at that kind of power level most RX-8's only put down around 250-270 ft-lbs of torque. These engines don't make that much, or so we thought.

Here is a RWHP graph of the highest producing turbo kits on the RX-8:

Mine is the 3071R @ 13.5psi, look at my domination!
