James’ Element-tuned STI in Maxx Tuning Magazine

The 2006 STI owned by Element Tuning customer James “MULE” Mulherin Jr. has a short feature in the September 2010 issue of Maxx Tuning Magazine.  You can view the article by clicking on the image above, or by downloading the 9.1MB PDF here.  This is just a preview feature though, so stay tuned for the full feature with dyno numbers once his car is retuned by Phil!

700 whp! Element Tuning Hydra, Hydramist, 07 STi, 1600cc, 92 octane and Q16

I had tuned this really beautiful 07 STi once before but we ran out of fuel so this time around we upped the fuel injectors to 1600cc so we could really see what she had.

For some reason all the dyno plots this time around had the chop during spoolup on every car I tuned so maybe next time we need to adjust the ramp rate.

Like clockwork this time the car tuned easily and without issues. First up was the pump gas and Hydramist which netted us 604 whp which is pretty nuts for a daily driver! Next we ran the new 1600cc injectors with Q16 and the Hydramist running 80% water and 20% methanol. Slowly turned up the boost, dialed in the AFR and a really easy 700 whp.

Element Tuning GT65 Bolt On Turbo, Hydra EMS, E85 fuel, 532whp, 07 STI 2.5

This is really impressive for a bolt on turbocharger running E85 and pump gas. On this tune the customer swapped out the header and it appears we lost some bottom end power over the old but peak power stayed about the same (on pump gas). All the dyno plots on this tuning session had the “blips” where the WG opens and I just noticed this time around the dyno was set to 150 instead of 120 so that could have something to do with it.

Initially I tuned the car with DW 1000cc injectors but for E85 we stepped up to RC 1600cc with the base fuel pressure set to 50 psi but the regulator diaphragm failed so we had to replace the regulator with an Aeromotive A1000 (don’t waste your money on anything else!). We also swapped in a TurboSmart BOV to better manage peak boost pressure and not blow open.

The Element GT65 Bolt-on really shined on E85 fuel especially given the car didn’t have anything done to the heads but a set of cams.

“Prize Fighter” from Grassroots Motorsports

by Scott Lear From the April 2010 issue

When it comes to our no-holds-barred Ultimate Track Car Challenge, the more cylinders, the better. Out of the 55 track-prepared beasts that entered the most recent competition, the top five finishers all had big V8 power. The next two spots went to six-cylinder racers—one with a turbo, the other with lots of revs and an exceedingly low curb weight. Squarely in eighth place overall, however, was a comparatively diminutive 2.5-liter four-banger.

The boxer engine in the nose of Phil Grabow’s 2006 Subaru Impreza WRX STI had less than a third of the displacement of some of the other cars. However, that didn’t prevent the Subaru from running at the sharp end of the pack with a 2:00.197 fast lap around Virginia International Raceway. A big turbo certainly helped, but power isn’t the only answer in the search for a quick time on track. In fact, due to heat issues, Phil’s Subaru was running in limp mode when it beat every other four-cylinder turbo at the event—as well as two Dodge Vipers and a full-race Ferrari F430 Challenge.

Element Tuning Time Attack 06 STi Hydra EMS 570 whp

Starting the new Time Attack season we wanted to freshen up the engine and test a few new parts. We started out rebuilding an Element Tuning Pro Comp engine but we switch up the bearings and the compression ratio of the pistons to see how they hold up over a season of racing.

Fuel: Sunoco 110 Octane with Hydramist (80% water)

With a new engine I really didn’t want to run it too hard on the dyno so I stopped at 27 psi. I made quick work of the tuning with the Hydra 2.6 software and had all tweaked in as few WOT pulls as possible. In my previous dyno sessions the 1000cc fuel injectors were maxed out so this time around I bumped up the fuel pressure to 55 psi giving me about +20 more flow so I could have a little safety margin on the injector duty cycle. Maximum fuel injector duty cycle was 83% with the 1000cc, A1000 fuel pump, and 55 idle fuel pressure.

I totally forgot that I didn’t like the billet compressor wheel I ran late last year which netted me about 30 whp loss over our standard GT65 wheel (GT35R). With the higher compression and the BC STG 4 cams it looks like we gained back that loss however. The numbers are good for this dyno so I’m happy for now with the improvement.

The BC ST4 cams required me to work on the AVCS mapping as compared to the Cosworth cams. I found that I had to carry the advance farther into the RPM range but in the end the Hydra EMS allowed me to get it exactly how I wanted it.

Having made some new changes to the car I wasn’t sure what the car would weigh in at so I had to have options available for HP so that I could stay in NASA TTU classification. At about 15.3 psi the car made 452 whp which should be low enough to keep me legal in that class.

Another sweet STi from the my favorite place on the west coast, Seattle! Not only does this 2007 STi look incredible it has the power to back it up!

What a beautiful car and it did not disappoint on the dyno. We were limited on both pump and race case so we just made a quick tune on pump and Hydramist making 506 whp before running out of fuel injectors.

We switched to a Q16/Pump/Hydramist fuel combinations allowing me to tune up to 624 whp before running out of fuel injector. When we switch to larger 1600cc fuel injectors we should be able to get another 30 psi on pump gas and probably another 60 whp on race fuel.
