As you may have seen in other posts I have been utilizing the Ecutek flash by Precision Dyno Tuning with excellent results. The car pulled very nicely before... but now it is a beast and the guys at the shop...as usual... complete professionals.

As you can see in another post, https://www.evolutionm.net/forums/sh...d.php?t=174439 , I installed the full range of Nisei products. After the install I did notice a little power increase and an approximate 2psi pressure drop.... easily fixed...turn up the boost

As soon as I got to the shop, we strapped her up to the Dyno and began tuning. The results were very impressive for a Mustang Dyno. 329HP/305TQ.

The intercooler is simply amazing. It flows so much better than the stocker. www.nisei-evo.com has actual temp/flow charts. The AFR was up a full point before tuning!! I am at the max safe level the stock injectors will allow to keep the AFR in a good range.(I am sure Nick will respond to explain better )

The results are netted from 22.5 psi tapering down at redline...
(which is maxed out on the lighter spring from the Forge UNOS boost controller) a mix of 93octane..1/4tank and 94 octane...3/4 tank.

I will be installing larger injectors this week, and I will post the results. The dyno graph shows to plots. The higher is the tune from 12.17.05, the lower is from 11.08.05. The mods are:
11.08- 94 octane
23psi tapering down...on the Defi gauge
Injen intake/upper intercooler pipes
Walbro 255
turbo back ext.
Forge UNOS

12.17- mix93/94 octane
22.5psi tapering down... on the Defi gauge
Nisei upper/lower pipes
Nisei Intercooler
HKS RS intake
TBE
Forge UNOS
Walbro 255

 

Wow nice numbers, but I would have thought you would have made a little more power than that, don't get me wrong, a 13WHP and 9WTQ gain is still good, but I guess I'm just so use to seeing the EVO IX make such tremedous gains in power that when it makes average power with a modification it kind of surprises me. I guess it's true as far as cost vs. gain, an upgraded intercooler with the stock turbo is just not worth it even for a IX. Still that's not taking anything away from what your IX did, because I've seen worst gains with an aftermarket intercooler and I believe some EVOs have even lost power. The stock intercooler is a very good unit and difficult to improve upon, the fact that you made 13whp with one is very good.

 

+1 pretty impressive to see gains over the stocker on the stock turbo.

 

So what do the stock IX's dyno on precision's Mustang Dyno?

Nice gains for I/C...

EDIT: Never mind, here we go:

 

Anywhere from 230-235 Torque and about 225 WHP. John's car is simply amazing, with just bolt ons he is already producing tremendous power. He and I took it for a spin after we tuned it and it felt awesome, incredibly smooth and very powerful. We are looking forward to the next two mods on his car , where we really see what the IX is capable of

 

your car was awsome john. and looks sweet to.

 

ohh nvm, i thought you said stock VIIIs were putting down 230whp..

 

Could you explain exactly why your car "needs" bigger injectors? Are Evo 9 injectors smaller than evo 8 ones? Evo 8 owners have routinely made more than 140whp over stock on the OEM injectors and have run 11s at 115+mph.

 

Correct me if I'm wrong, but the car gained 13hp and 2qt after the tune that day? How is that in the car on the dyno?

 

I also think we're forgeting 'power under the curve' which I'm sure went up to. BTW, has anyone yet put an HKS 264 exhaust cam on with MIVEC? Just wondering, because that's what someguys did with a Silvia. The blacktop engine has a variable intake cam, so they left it alone and put a 264 on the exhaust side.

 

Very good numbers on a mustang dyno without cams. So IX's base 225whp on that mustang? That sounds more reasonable over the 05's than some people are saying. What does a 05 baseline there?

 

very nice done PD!

 

sorry it took so long for the response. There is more power available, but I am at 85-90% duty cycle on the injectors. To add more fuel would not be safe, in fact I feel that I am pushing the limits as it is. The stock injectors are 560cc. This would dyno at least 360hp on a dynojet, so we are well over 100hp > stock.

There is def. more power under the curve. The numbers may be low, for the upgrade, but the potential with this unit is far more than 10 hp. Keep in mind the intercooler does not directly make HP, it merely adds flow at a cooler temp, and the Nisei unit does this incredibly well. Besides, it looks good...lol!

 

Just wanted to make sure you knew this was not necessarily true. First of all, you can't claim that it was dyno AT LEAST 360. There's a good chance it DOES dyno 360whp on a Dynojet, but saying "at least" is exaggerating it just a little. Next, even if it is at 360whp on a Dynojet, that is not "well over 100hp > stock," since the IXs are dynoing 270-275whp on Dynojets. That puts you 85-90whp over stock using that comparison, but the only real comparison that matters is what your car dyno'd stock on that dyno. I can't remember if you did that or not. If you dyno'd 225whp stock at PD, then you're 104whp over stock, eh.

You consider 85-90% duty cycle to be "pushing the limits"?

 

Congrats on the safe but POWERFUL tune!
