That's why we spend countless hours on the dyno. Testing everything at different levels. Add parts, retest... It goes on and on.

Look at the EXO 8-9. We all know what it will make with basic boltons on pump with a tune. Add meth and you can turn it up to..... If you want to make over 600 you'll need..... The clutch will hold.... HKS cams will add about....

All of that data comes from testing and pushing the cars beyond what the average person will do.

Ahha!

Now it makes more sense to get that extra ~50whp. You turned the boost up 5psi and added C-16 to the tank.

And had to get around the overboost and MAF/MAP issues.

 

So how bad will these numbers change with sh*tty California 91 octane?

 

So far from what you guys have seen..do you believe that the X will reach 400whp on pump??

 

I might have a different opinion after we get our software but for now I'd say no. I'm not sure how much power the MIVEC tuning is good for.

-Jeff

 

Well if its anything like the IX...a good portion of power can be made from mivec. I have seen over 15whp difference just changing mivec maps on my IX and the X has it on both sides. Thats too bad it only made that much power on some C and that amount of boost though. I would suspect once you guys can actually tune it the numbers should be impressive.

 

^Well, it was only 2 gallons of c-16 mixed with pump gas, so I would guess that it could make more power with a full tank of the stuff. Until they can tune the ecu and adjust all the various parameters of it, this is really up in the air right now. I would guess that with a proper tune, taking control of the mivec system along with everything else, I wouldn't be surprised if the car hits 400 whp on a dyno jet, 340-350 on a mustang. However, if it maxes out at about 370 on the stock turbo, that's still great and I'll be thrilled with that. That's a lot of power for such a basic setup!

 

nice numbers!

 

^^Well two gallons with almost no other fuel left can still make the octane quite high (100+). Being as they are basically tuned but have no Mivec adjustment and are running 28-29psi my guess would be with a full tune and pump gas probably about 370-380ish whp. Whos knows maybe it will be surprising.

 

You also have to keep in mind that the X doesn't have EVERY part superior to the 8-9. The turbo IS smaller. This will hamper potential. And while there is MIVEC on both sides, the exhaust ports in the head are smaller too.

 

For those Evo owners who will never pass stage 1 or 2 performance, every part on the X is superior. All the results we are seeing right now support this. It is speculation that the turbo and exhaust ports will become an issue later on down the road. Speculation because no one has gotten there yet.

 

Agreed.

It's called point of diminishing returns and a little logic. The 15G turbo is only going to supply but so many oxygen molecules no matter what you do to it. The engine is only going to be able to produce but so much power with that turbo. Also with the engine parts itself. The car isn't limitless.. so we can make certain logical assumptions. Yes, the X is more efficient with the given oxygen it receives, but this makes it better in it's efficiency - not it's turbo (bigger is always better concerning this). Less weight is always better than more...more aerodynamic is always better than less...etc.. etc.. So where it excels in one aspect, it may have to make up for in another aspect that isn't so "perfect".

 

Boostez, you do know that I am intentionally giving you a hard time about the turbo, right?
I know what your saying man. It's all good.
