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.

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.
