Here are my dyno results with the GReddy Turbo and Interceptor X EMS. This was done on a mustang dyno, using relatively concervative AFR. We had to pull a lot of timing because of the horrible gas we have in CA. These numbers were done at about 9.5psi after the car had cooled down. The final tune gave 225whp, and was done at 11-11.5psi. If we had let the car cool down, I think we could have gotten another 10-15whp out of it. I am running the RB exhaust, and RP high flow cat.

 

wonder how much extra you can get out with the turboxs exhaust, should be a lot less restrictive compared to rb.

 

I'd like to hear it on a turbo'd car. NA is LOUD!

 

That's good numbers on a mustang gyno

 

Nice, Moostafa. How is the drivability with the Interceptor now that you have it tuned? Also, it looks pretty heavily smoothed. I'd be interested in seeing some Interceptor AFR data a little less smoothed. Got any? If not, got any impressions you could share?

Thanks,
MD

 

Any smoothing is done by the dyno software. What you see is straight from there.

I'm interested in drivability too.

 

Umm...Yeah...okay....

You can also change the smoothing parameters and get un-, or less-smoothed data if you so choose. I'm asking him if he has any of that...

 

Single exhaust on the turbo have shown up to 10 lb.-ft. of torque.... "or so I've heard "

 

Thats what I was going to say, I believe mustang dyno's are always a bit lower in their readings compared to a dynojet.

 

Mike, does it feel like it loses power after 7K RPM? I'm curious how a Greddy RX-8 would respond with the VDI disabled.

EDIT: Hey I just realized you dynoed at FFTEC. That's where I had my last dyno at 188 HP.

 

You made some REALLY nice numbers from your dyno. I think that mine suffered from having to back off the timing to such a large extend. Without doing so, I was pinging everytime I'd go WOT. As far as the power, I honestly can't really tell there is a loss of power after 7k. Perhaps after I get used to driving it I will, but right now, I'm struggling not to hit fuel cut off, because you get to redline so quickly.
Drivablity is fantastic. It really feels like the car came straight from Mazda like this. Only thing I don't particularly care for is the white smoke out the tailpipe all the time, but I know that can be resolved. I could try to get the original dyno curve from FFTEC this weekend if I can find the time, to compare those numbers to an unsmoothed AFR.

I was thinking about getting that mod to the interceptor to monitor my AFR, so that I can fine tune them slightly leaner. Should be able to pick up a little more power there too.

 

Nice numbers, the FFTEC guys are pretty cool!


Xyntax, what have you done to your car to pull 188 on a mustang? I know we've had this convo before, but i dont remember

 

Whats up with the headers? I want to see what you can get with those, and tuning.
Yeah, the guys there at FFTEC are hella cool. I do have to double check my receipt though...

 

I only have REVi intake/CAI, hot plugs, and CZ street-tuned map after reflashed with "R". The headers are sitting in my room. Any idea where and when we could get an install session? I know there's gonna be some guessing since it's the first time for most of us. We might need a lift due to the tight room in the header area. Did you install your turbo on just jacks?

This is Moostafa's thread, so let's not get off topic. Your AFR is just about right to get good reliable power, but how far did you pull timing? How was your timing map setup, did you mimic the stock setup? You know, gradual rise up to 6K and then it stays at 30 all the way. Does the I-X enable you to control timing split?

BTW, I was informed that the VDI stays off for the I-X. Nice

 

"Does the I-X enable you to control timing split?"
Yes it does control split, it also retards the timing as boost pressure comes up.

"BTW, I was informed that the VDI stays off for the I-X. Nice"
Actually it is user definable, so is the SSV. In Mikes case the rev cut is @ 9250 and the VDI opens at 9500. (get it?)Scott

 

^ Got it. Thanks!

 

HAHA

 

Spill it already

 

Significantly Lower

WHAT???

 

Sorry to go off topic again (in my own thread!), but if putting on the headers is anything like putting on the exhaust manifold on the turbo installation, then it should only take 2-3 hours. The only thing I used were jackstands, a jack, and a brick. I'd like to take a look at it first, so I know what we are dealing with. I'd be down to do it in my driveway.

As far as tuning, I have really limited knowledge about that sort of thing, but am trying to learn here and there. I wouldn't dare tune my own car right now, so Sean at FFTEC did all the tuning, and consulting with Scott.

 

^ Cool. If the weather permits, maybe we could do this install this month. As for tuning, I wouldn't tune my own either if my engine is boosted. This is one of the reasons why I'm trying to experiment with my car while it is still in N/A form. Once I hit the ceiling for N/A, that's when I go FI, and then it's another chapter of learning from there.

 

ugh... smrx8 on the boards got 216whp N/A with tunning w/ the RIC Shaw ECU

With 55shot nitrous he got 243whp and that was on a mustang dyno.

 

yea that was smrx8 car, how much is your 8 pulling btw? don't throw stones if you live in a glass house...

besides like mentioned above this is with 91 octane didn't smrx8 dyno with 93 gas?

 

Ca 91 gas = 89 other states = why we had to pull so much timing
