Great Gains

From Subaru simple bolt-on setups to all-out track motors we have you covered. Tested above was a 2017 WRX STi max effort stock turbo on ethanol vs. it’s new bolt-on dominator turbo / reinforced engine setup on ethanol picking up 200whp at redline over its previous stock turbo. Spool rpm is surpassed as early as 4000 rpms. This car now has a very long powerband right to 7300 rpms. With careful modification and calibration you can have low and high rpm power. Our recipes for longevity and power speak for themselves. Interested in learning more: contact or 508-762-1769.
