Event: Phil Grabow Hydra EMS Tune
Location: Element Tuning, Gaithersburg, Maryland
Ambient Temp: 68.92 degrees
Elevation: Sea level
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

This was originally written up in April 2008 on NASIOC, but its relevance continues to this day. Plus, given how everyone is trying to save money these days, $1899 for a 450+ whp turbo is a much smarter purchase than spending well over $2500 for a rotated turbo kit that puts out the same amount of power and even spools slower.
This was the maiden voyage for our GT65 stock location turbocharger and for being internally gated 512 whp is pretty impressive. Not only did it impress on the dyno but also took the NASA Time Attack Unlimited class (TTU) win on both days at Virginia International Raceway.

Built by World One Performance, Phil traveled to the Pacific Northwest to tune this beast of an 07 STI. Utilizing a number of Element Tuning products, including a GT52 turbo, Hydra EMS 2.6, and Hydramist, the car was tuned with Q16 race gas to a powerful 475 whp and 534 wtq. This is a full 75 whp above what a GT52 typically makes on pump gas, which instantly put a smile on the customer’s face. For more information on this build, please see World One Performance’s blog here:

If any of you haven’t been to VIR you have to do yourself the favor of going. What can I say but this track not only takes skill it takes big %#*! With a beautiful back drop and cool weather it was on!
With largest field of TT cars ever this event had over 35 cars going for the win in various classes. To make this more fun than ever we had 5 TTU cars which means Hoosier Tire contingency would be up for grabs. Sharif with the Forged GTR showed up with slicks and Michael Woods in his Z06 who broke my record at Summit Point would be my biggest competition. A few other Nasioc members were there including Boost Junkie (Dan), MSP608 (Justin), and Martin K.
My weekend started with a retune possibly compensating for a new turbocharger combination resulting in a 40 whp loss over our tried and true GT65 combo. The car was detonating with the new unit so I had to detune it but got it running well.

Another Redline Time Attack scorcher in the books. With temps in the high 90s track grip was very low but this didn’t slow down the action very much.
We scrambled to get an engine together for this event after suffering an ARP rod bolt failure which trashed our block and bent valves in our head at the GRM UTTC.
With the motor back in the car late Friday we headed off to South Carolina on Saturday for our 10 hour journey. Missing all of Saturday practice and then having to take it easy in practice session one to break in our engine definitely hurt my ability to learn this tricky track.
Carolina Motorsports has a mix of very high speed “kinks” but also a mix of extremely slow and sharp curves.
