Factory Pro Tuning - The world's largest producer of aftermarket velocity stacks!

What are they?
There's something that makes the susceptible ones of us to instinctually react to the sound of an engine at high rpm, running as perfectly as possible - on each and every cylinder -
It's that sound like Roger described as - "The sound of "rippin' sheets" going down a straight."

Something that makes a "not just good, but perfectly tuned" race engine sound that causes the hair on the back of you arms rise up.......

First step it getting the intake tract lengths correct....... Then, intake cam set perfectly for that engine, then a matching exhaust for the cam settings, getting the ignition timing perfect at every rpm, eliminating ignition scatter, then, finally, providing the correct amount of fuel on each cylinder, at each rpm point...

That eliminates, except by luck, "Tuning to an A/F Ratio" as the final answer to tuning...
Tune to BEST POWER. True HP

It's not that easy...... 98% of engines at a racetrack won't even do that.
Kudos to the tuners who can consistently pull that off! They are the stars in the industry.

Take the first step with a set of these power adding
Factory Pro Superflare Stacks!

The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved.
