GT3

Yesterday, the guys at AWD, here in Coral Springs FL, spent the better part of the day until 11 PM dyno tunning my 2010 GT3 together with Evoms, which already had the Akrapovic race exhaust system. You know a shop is excellent, when they dont mind working almost till midnight to get things done. Many thanks to Mike@AWD Motorsports and Evoms.

I had previously done a baseline (RED), and later a run with the Akrapovic Race exhaust system (GREEN), at AWD Motorsports, to really be able to compare each successive mod done. The (BLUE) run is the custom Evoms tune/race gas run together with the Akrapovic race system.

I'm very pleased with this combo set up. The Akrapovic race system, alone, made huge gains at 4.3K and 5.8K rpms, and well as consistent gains throughout the power band above 3.7K rpms. And the custom tune/race gas, made consistent gains everywhere, improved better lower rpm power and torque delivery from the 3.7K to 3.2K rpm. The custom tune/gas alone, showed an average of 12 to 15 whp gains through out the rpm band and I really like the fact the the tune's peak gains are from 6K-8.5K rpm, 20 whp and 15 wtq.

The exhaust/tune/race gas combo shows an average of 32 whp and 24 wtq gains from 5.5K rpm to the redline at 8.5K rpm! And about the same from 3.8K rpm all the way up!

All runs are SAE corrected on the same Dynojet. Attached are each runs, conditions. If you noticed, each run, after every mod was done at worse and worse weather conditions. The dyno results from yesterday was dont a 95 degrees .... More custom tunning will be done in a couple of weeks, and the Mk2 RS intake will be added together with a little something else

Going to PBIR tomorrow for "testing" According to 2 shops down here, the car weights 2,965-2975 lbs with half tank of gas, not bad with 423 max whp and 311 max wtq

Very nice..

Very nice gain! How many dyno run did it take to tune your 3? I am working on my shop here to get the proper software to start dyno tune GT3. I don't feel like driving all the way to Arizona ... or Florida

Great exhaust and gains - congrats!

Thanks guys ^ ^^

If the shop has the equipment to do Evoms in-house, and send the files back and forth to evoms, as the car is dyno'ed, doing a custom tune should be no problem. Sharwerks can do it for you (but 300 miles from you?). Maybe even a dual 91/MS109 octane map? I don't know how many runs were done yesterday.... but more tuning will be done in a couple of weeks when I make some intake changes. Will test tomorrow at the track and will do some 60-130 v-box pull as some as I find someone with one down here

Sharky don't have dyno facility. I don't think there is anyone in Northern California that have the setup to custom dyno tune. So you are installing the 2010 RS airbox? I guess you will need to modify the rear decklid to allow air into both opening on the airbox. That will be a very interesting experiment. Just 1/4 pull tomorrow?

What was done with respect to the "tune" portion??

GT3

AWD Motorsports, together with Evoms, did a custom dyno tune, using a 105 (really a 100) octane gas I requested. The results from the tune are, 20 whp and, 15 wtq at 7.1K rpm (SAE). I think its excellent, since those are at the top, were they will be the most useful at the track. The tune's gains are very consistent all the way to the redline, just like the exhaust's gains. I went to PBIR this weekend and the car was a blast to drive Probably going to Homestead this weekend coming up...

Nice. I love an optimized car....perfect.

My 930 has to run a race/92 blend even for street use - 514HP/493TQ from 3.4 liters pretty much requires it

Just as a reference, here are the same runs in STD just to compare the difference with the SAE in the OP:
