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.

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.

Why go rotated when you can save money with a GT65?

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.
