Just a little background on my car cause i don't post on here too often.

The power mods that i have are:

Ams fmic,intake,uicp, and licp. Speedcircuit catback, Ur resi test pipe,Xtreme boost 02 dump,Dw 800cc Injectors, Walbro 255,Kelford stage 2 Cams, valve springs, and finally a ported Forced performance red turbo.


Well, It was a long and hot day today. It was in the upper 80's, and the rain did not help anything at all.

The car started with 343hp 310tq, and ended up with 374hp 326tq.

Things to note:

Fp red does not like pump gas. Meth is in the works, but stock clutches in my opinion will not hold the extra power that it brings.

Car is an MR with extra drive train loss(sean stated that gsr's would be in the 400's with this setup)

Car is only running 25lbs of boost right now, 1 more psi then the stock turbo was. The fp does not start to shine until 26lbs

The Tranny is shifting great, and is holding the power very nice currently, But as gunzo said on my old dyno thread is that the tcu is holding back power from this car. There is no way you could bolt on a fp red and cams with tuning and only get like 16lbft of tq, it just does not add up.

The car has some lag which is a given with this turbo, but the overall feeling is much much better than stock. There were certain deadzones in the lower end which the car felt dead, That now is not an issue.

The revlimit was set to 8k. One thing that sean pointed out was that this car is much more drive able now. The car still pulls and makes power up top even approaching the new rev limit. He was very impressed with this car and so was i.

Dragstrip numbers to come.

 

I'm really impressed with these numbers on an MR, and I can't wait to see what numbers your MR puts down with meth. The tq number is a bit suprising, but I'm guessing that's probably a good thing with the SST. Congrats!!!

 

So looks like there were some gains but not as large as expected for an FP Red and Stage 2 Kelford cams. I've heard of MR's getting angry on dynos where it basically reduces power if it detects the slightest difference in front to rear wheel speeds. The good news is that it on the street all should be fine and will likely be faster than what the dyno is reporting gains wise over the stock turbo.

What kind of baselines does that dyno normally have for Evo X's? Definitely report back when you get Meth in there to allow higher boost on the FP Red, and likely the lower torque is a good combo for the MR SST setup anyways, as long as it holds good torque right to redline. I bet a moderate launch on a drag strip somewhere would reveal some nice trap speed gains so if the dyno won't behave then just test it at the track.

 

do you have any dyno sheets of what you made prior to the FP Red? Like you said, the tq numbers aren't very impressive at all and are only a bit higher than a stock turbo, but don't peak until after 4000 rpm, whereas the stock turbo peaks around 3400. I'm curious as to how the SST will hold up. The hp numbers do look great though.

 

I think his first plot was comparing the stock turbo to the FP Red with cams. Like they mentioned there was some SST tranny/ECU interaction on the Dyno though. We'll likely have to wait for some trap speeds at the drag strip for a real world performance comparison.

 

You're right...I missed it...I honestly think I prefer the old tq curve better, but there's no denying the new hp. I know exactly what he means by the SST limiting tq all too well

 

Glad to see turbo and cams upgrade working well with SST! although the gains may not be what expected, Im sure there will be ways to amend the TCU in the future and unleash the hidden power.

 

So the engine is making the power but the TCU isn't allowing it to be transfered? Or does it actually start cutting fuel or something?

Your numbers are very similar to my initial FPRed run, but with stage 2s going in this weekend, I'd like to see 400+.

 

I can see the MR TCU working it's "magic" in that power curve. I'd be interested in seeing the datalogged RPM on that pull.

I should have some more data about this soon. (thank Gunzo as well).

 

I'm not sure if the actual cause has been figured out yet, but I do know my tuner said something was fighting his settings with the AP.

 

Good info. on an MR. Thanks for the post and please keep us updated.

 

Can you eleborate the something a little bit more? How does it limit the power?
ie: pulling timing, traction control kicks in, clutch slipperage....etc?

 

Throttle Opening and Clutch engagement

 

That's the problem...we don't know...not yet at least...but something was limiting boost and that wasn't doing what the tuner wanted it to do...like it was protecting itself from "something"

 

Maybe Sean can chime in and provide that info.

Once this phantom issue is fixed watch out lol.
