Default Element STI Hydra 678 HP All Boost!

What can I say, the dyno speaks for itself: 678 whp and 634 ft/lbs of torque all turbo using VP C16 fuel.



The dyno is a Dynapack 3500 owned by Slow Motion in Ohio.

This STI had once before been tuned by me to just under 600 whp and ran a quarter mile time of 11.0 @ 135.5 mph without N20. I feel the Dynajet I normally use reads on the low side or the car simply picked up a little more power in the real world. Fast forward a few months and some new modifications were performed. The heads and block were decked to get a better seal on the head gasket. I requested that the thinnest head gasket be used so we could benefit from the slight increase in compression ratio. An unequal length header was also installed, along with a fresh GT35R 1.06 turbocharger. The engine is an Axis Power Racing engine but still uses the stock block and the heads are ported with larger valves and 272 cams.

Here’s a quick list of mods:

Axis Power Racing STI engine (rods, pistons, stock block)
Axis Power Racing STI heads (bigger valves, porting, springs, 272 cams, no AVCS)
Element STI Hydra EMS (custom tuned by Element)
1000cc injectors
Aeromotive Fuel pump
Unequal length header
GT35R 1.06 AR

Here’s the interesting part, with those modifications, 2 psi more boost (29.2 vs 27 absolute), and more tuning, we hit about 648 whp. So where did the extra power come from? Removing the intake completely and bypassing the power steering pump netted 30 whp more at this power level. Unfortunately we did not test these two items separately but I suspect the majority of the gain was from the removal of the air filter.

Tuning was what I consider moderately aggressive but at this power level we didn’t want to push beyond this point. The AFR was 12:1, boost was 29.2 psi (absolute), and ignition timing peaked at 26 degrees. The 1000cc injectors hit a peak of 98% duty cycle.

Sorry guys but at this point this car will never see the drag strip as it is and has been for sale. Alex wanted me to retune the car so the new and lucky owner wouldn’t have to. Here is a link to the car's for sale page which also lists all modifications: http://forums.nasioc.com/forums/showthread.php?t=914934

Let the flaming commence

Thanks,
Phil

Either he's a dumb bastard or is building a PMSing mother of all monsters. <--Which means "Damn, this guy can build a sick car!"
Oh yeah, that 50whp at 2k is AWESOME! I'd drive everywhere doing 2k! <--Which is a joke, if you didn't get it, kill yourself.
Damn, he's buying a house instead of a new car . . . <--Which was after I read the other thread.

The rev limit of the car is actually higher but we decided to only dyno to 7200 rpm (by the way this was 7600 rpm on the tachometer?) as the car is for sale. We also cooled down the car before each pull to reduce stress as much as possible. As you can see though a lack of high RPM power is not the reason for cutting the rpm short.

Thanks,
Phil

Gadiel,

Thanks. This is the car I had mentioned in our conversation about converting the camshaft pickup of the STI to the camshaft sprocket pickup of the WRX for use with JUN 272 cams when using the Hydra EMS. Give me a call if you need some guidance.

Thanks,
Phil

Dude when you grow up your understand that somethings are more important in life than having a fast car. I would sell a car like this to have a house. In the long run the house will buy another car and i bet it will.

Thats why i bought my house first then went for the car.

I shouldn’t even dignify this with a response but you're way off base as I’m sure others are also. Often these huge power cars skew the way the graph looks and you think, "Wow that car has no bottom end power." Well when you see a stock STI graph overlaid onto this one you'll see that the small sacrifice below 4200 rpm is well worth it for the area under the curve you gain after 4500 rpm in both torque and HP. This was taken from a stock STI dynoed on a Dynapack 3000.



By the way a stock STI also makes about 50 hp at 2K rpm.

while the NUMBERS may indicate a similarity between 50hp @ 2krpm on a 1.06 gt35r, and 50hp @ 2krpm on a vf39, there really is no comparison. as i said before, this setup is sick. but lets not say that its going to be as responsive/powerful in the low end as a vf39. just cause the dyno says so, doesn't make it the truth. there is NO comparison between how a vf39 sti feels before 4000, and how this car feels before 4000, lets be honest.

i dont think he ever said that it feels the same... infact he said little 'sacrifice' on low end is well worth it.

impressive, but I am not a fan of this 4000rom "wall of death" tuning... id like to see it a little wider for street use, but for a drag car, its pretty cool
