E85 2200 Inj Element Tuning Pro Comp Engine, Hydra EMS, ET GT65 Turbo, 597 whp, 07 STI

What an animal this STi is on E85. Not only did it belch out 597 whp at max boost but it also made 530 whp at a reasonable 23 psi.

The dyno fans were completely inadequate and I’m surprised the car made as much power as it did but he did have heating issues as a result. I’m sure with proper fans we could have seen as much as +30 HP.

Element Tuning GT65 Bolt On, Hydra, 452whp @ 22 psi, 07 STI 2.5 Pump Gas

This is really impressive for a bolt on turbocharger running pump gas and only at 22 psi. The plot didn’t turn out as smooth as I like but the AFR was within .1 and timing was smooth. I think we just had a little boost oscillation going on. I also find it difficult on the Dyno Dynamic dyno to load and unload just right resulting in a boost spike and then a little oscillation (too many buttons to press. LOL!).

Initially we tuned the car at OEM fuel pressure but the DW 1000cc injectors were maxing out so we bumped the fuel pressure to 50 psi just to get the car tuned safely. The plan is to get some larger 1260cc injectors and the Hydramist system to turn things up.

I honestly couldn’t believe the power we hit with the Element GT65 Bolt-on especially given the car didn’t have anything done to the heads but a set of cams. I was tuning other cars this same day with rotated 35R kits and head work that were making the same power at this boost level. This car has had a rough past with bad tuning and engines but World One Performance sorted out the car so I could do my job. I was really happy for the customer this turned out so well.

With larger fuel injectors I think we could have turned up the boost a little (maybe 1-2 psi) for another 30 whp or so. With the Element Hydramist we should be able to add an additional 4 psi and get this car close to 500 whp on pump gas.

What else is there to say but WOW! I had tuned this car once before but we ran out of fuel and the clutch was slipping. Fast forward to a new Element Clutch Masters, larger fuel injectors, higher fuel pressure, and what do you know the FP diaphram fails. We fix it and climb to 668 whp on 50% Q16 and pump gas along with the Element Hydramist.

The car had a little more in it but given the problems with the FP regulator resulting in extended tuning time the owner felt that just about 670 whp was even too much for a road race car.

524 whp on 93 pump, 629 whp on Q16

Event: Phil Grabow Hydra EMS Tune
Location: Element Tuning, Gaithersburg, Maryland
Ambient Temp: 68.92 degrees
Elevation: Sea level
Weather: Raining
Track and Conditions: NA
Tires: Michelin Pilot

I wasn’t really sure what to call this turbocharger as it’s based off of what we call the GT75 but this is a GT series housing with a Garrett 75 lbs compressor wheel and a Tial 1.03 exhaust housing. This was changed from the FP HTA since that was damaged (oil seals).

We made a little more power on pump 93 hitting 524 whp up from about 503 whp. It did spool a little slower than the HTA but had more top end. Very impressive for pump gas especially on this dyno!

On VP Q16 power was very good. There was some boost taper and overall we wanted more boost but that’s all the WG had in it. Upon further inspection we pulled the WG apart to upgrade the springs and noticed the diaphragm was folded over so this could have caused some issues. We’ll get stiffer springs in there and turn up the boost!

Target boost will be 35 psi which this turbocharger should have no issues running. Tuning went well and power came easily with boost. So far no sign of detonation issues as boost was increased or any other difficult symptoms. We did have misfire issues the last time the car was on the dyno but that was corrected with very tight spark plug gaps.

Again this setup has been similar to the other large turbochargers I’ve tuned with the Cosworth cams and or head package. It just doesn’t like variable cam timing advance but really big turbochargers like this are all about the top end.

On the next runs I may push the RPM a little further if oil pressure looks ok. For now I’m limiting the engine to 8k rpm but clearly it will make power to about 9k rpm
