This car HAULS

This is the Miller Performance Test car. It has all the developmental parts and systems running on it and serves as the test platform for all the prototype parts. Pushing 488 RWHP on a stock bottom end at only 17 PSI, this car screams.

It is the e34 that ownders, Brody Saari and Dan Miller, have the most passion for and it really shows in this work of art. Running their stage 2+ Miller MS engine system, and full 4" stainless exhaust, this is one unique car. Tuned on the factory ECU, the tuning on this car is unprecedent.

M30 4" Stainless Exhaust

"It's cool to have a Semi Truck exhaust coming out the back..."

- Dan Miller-

In development of our hardcore M30 Street engine, we were hitting a wall at 450 wheel HP. With a stock bottom end, and a 3" exhaust, 450 HP seemed to be the safe and consistent limit. With the addition of our turbo cam, designed in house, and the 4" exhaust designed and manufactured in house by Dave at Passenger, we were able to achieve 488 HP at the wheels! Keeping things consistent, we are putting more power down than a brand new M6 which we also dyno'ed on our Mustang Dyno.

We were dumping the waste gate to atmosphere at first for fun, but quickly realized it was way louder than anticipated. This is a street car, not a heat magnet.

With our Garret, ball-bearing GT35, you have instant boost, and amazing, useable power. Our exhaust is made from sanitary grade American stainless welded in a fully back purged environment, as are all our in-house exhausts. This is to ensure our lifetime guarantee we offer on our exhaust systems. With our fully forged and balanced engine almost ready to rock, our initial goal of 500 HP is now going to be too easy. 550, maybe 600 at the wheels with pump gas? Who knows, you will have to wait and see.
