Just got back from a dyno session on a AWD Dyno-jet and wanted to share my results.

I have a basic 24/18G Protomotive kit.

Protomotive K24/18G turbochargers
5 bar FPR
Protomotive ECU
Ported OEM Headers
Greddy PRofec B-Spec 2 boost controller
EVOMS Billet Diverter Valve
BMC Filter
Fabspeed LOUD
EVOMS upgraded wastegates
GT2 Intercoolers/ Stock hoses
Custom Aluminum Intake Plenum (FVD Style)
70mm intake hoses to turbos

Results: First run was with the boost controller set to 1.1 BAR (low boost setting). 507WHP @6700RPM (I let off early since the AFR were a bit lean) Looking at the graph it was clear the car was still climbing in power.

Next run was with the controller set to 1.3 BAR (high boost setting), the car made 535WHP @7100RPM. Once again the AFR went lean running 13-14.0 from 5.5K RPMs up. I will be sending in the ECU to Todd for fine tuning and hopefully get the AFR's in the 11's/12's. All runs done with 100 octane. Overall very happy with the setup, car is SCARY FAST!

 

you should dyno it on 93 to see what it does. unless of course you drive around with race gas all the time

 

You should not dyno on a AWD Dyno Jet unless you want a new front diff as well.

 

News to me, please explain....

Also, I noticed the front wheels were spinning at a slower rate than the rears until it really got into boost??

 

You must run a mechanically coupled dyno unlike what the DJ is. A Mustang is about the safest bet. Your car has a viscous coupling which with friction will lock up to pull more power to the front wheels. The DJ does not simulate real use and there for the front diff will over heat because it is rolling at a different speed and can not change lock up. It continues to get to the point that the front diff will split from the internal pressure of the coupler exploding. There have been so many cases of this. If your front wheels were not rolling the same speed you more than likely have done damage especially at this level

+1 Perfectly said.

 

have todd look at the graph... u should not be seeing 13s.....

Wow - Amazing how consistent Todd K is with this set up. I basically have the same set up and went 531 AWHP. I was running around 1.38 Bar, but my AFR's never went above 12.5 and heald steady at 11.8.

I was 509 AWHP in the "Low Boost" setting

Mine is the same set up minus the custom Intake and GT2 Intercoolers.

He already knows what it will run. The first run was on its low boost setting (1.1 BAR), and it made 507 AWHP....which is what he will make on pump gas. It will make the same power on 93 as it will on 100.

Remember, higher octane fuel does not add power, in and of itself. It only allows for more power to be made by either advancing timing, or running more boost.

I had pretty much the same setup and I made the same power on low boost with 93 as I did with 103.

 

Great numbers, Don. Congrats!

P.S. - Heed Stephen's advice on the dyno. He knows what he is talking about. He's being doing this stuff for a few years.

 

I dont think he ever answered if he pulled his driveshaft or not but I dont know of any DYNOJET owner that would let a 996TT on there awd dyno with out pulling the shaft. but the way his numbers read I really dont think that he made all wheel passes. Dgreen correct me if im wrong.

He didn't disconnect the shaft.

 

Yeah I broke both front axles by doing this... My front diff as far as I know came through it UN damaged, but stay away from this situation!!!!!!!!!!

Congrats Don and thanks for posting the numbers. I really like your set up.
