NorthWest RX8 Dyno day pics, etc.
Thanks to those who made the trip out! I think there were as many rx8 owners who just showed up to hang out, as there was who actually dyno'd. Fantastic! ![Smilie](https://www.rx8club.com/images/smilies/smile.gif)
Here's my car's 'before and after'...the redline is my car last year, Stock w/ M-Flash, < 3K miles
The higher line is my car today, with R-Flash, RB intake and RB Catback, and 16k miles. Fairly substantial gains in the higher rrpms, I'd say. Over-all peak power went up by 11, but more at some points in the curve - as shown the difference is greater.

Here's another - both were 1st-6th gear runs. Ignore the choppiness of the 1st few gears, the car was shaking on the rollers. Note the substantial (for a N/A RX8) increases between the two plots. This run (5th gear) was my car's highest number-reached, of 197.

Group watching a very nice MS-Kit RX8 run. I say the MS kit gave him power, as he made 197whp with just a RB Catback as his only mod. Unknown flash - 27k miles.
More Black MS Kit

Nice pictures as always, Darin.
The first picture below your dyno charts is very interesting. If it is an RX-8, it has more than just a custom intake manifold done to it. That thing have a Hemi in it?

I LOVE ford Engines. :D
I How did YOU get back so quickly, Kevin?? lol...I got to my Dad's for taxes in Kent around 3:20...left there at 4, got home and started fixing pics and vids.
:D
And yeah, w/ my new 5.4L Kenne Bell SC'd V8, I've lost my car's 50/50 weight distro - it's worth it, however.

Raw scans from Carb Connection
I picked up 16.9 RWHP and 6.2 FT/LBS of Torque over last year. Mods are Unorthodox Pulleys and the CZ. My fuel map is not perfect, and the timing map is zeroed. I did not have time to get the Innovative Wideband installed to properly tune the maps. I used an older fuel only map, and it looks like 13.3 at the peak HP. Need to fine tune it now. The only other bolt on I could add will be the header.

This really bothers me - Note TaeYung's dyno (blue) over-lapped with one of my runs.
TWENTY-SIX HP difference...and wtf is up w/ my A/F ratio????
![](https://www.rx8club.com/attachments/rx-8-multimedia-photo-gallery-6/68362-northwest-rx8-dyno-day-pics-etc-darin_taeyungdyno.jpg)
I'm REALLY hoping the 11K miles more his car has is the difference.

Yeah - did on one run. The other guy did on a few runs.

On my car's motor? I expect 200whp eventually - or, 238hp at the flywheel - what the car SHOULD have had, stock.

:D
Actually, the engine was from a Mustang Cobra - 550whp, if I recall.

I thought Cobra's were 4.6 DOHC, but I don't keep up on em as much as I used too. Those cobra engines sure do sound good thru a Borla exhaust, just a mean growl.

Darrin: I think part of the difference comes in the way the ECU handles the closed loop to open loop transition. Yours went into open loop later than his....the leaner A/F in closed loop won't make as much power. Your A/F was the same ater the transition. It seems that the load variable with time must alter the transition point. If you can remember if you went straight into 5th without a coastdown....or if you had a wait to drop the startup RPM it might give us an idea what happened. I got the scanner working on the way home(...and got some tires too ![Big Grin](https://www.rx8club.com/images/smilies/biggrin.gif)
)as per usual
I really wanted to get logged runs that would have shown us a lot of the data that we need to see what the variations are caused by.
Better luck next time I guess

don't forget about that twin-turbo gto up on the lift
though i think the boosted and juiced c5 wins in the wow factor department
kudos darin for putting this all together!
