Dyno Day

There's nothing quite like watching the numbers climb on the dyno.

The anticipation. The sound. The results.

At FSi Racing, every tune is focused on maximizing performance and drivability so you can get the most out of your build.

Another awesome one out the door! This car came to us with a hurt lifter.
The shop ended up purchasing this hot rod and completely going through it before one of our good buddies ended up buying it.
Thanks to Broc at Shaker Inc. for doing the machine work on the short block and our team here at FSI for the meticulous reassembly and addressing every issue this car had.
On only 9 Psi of boost it laid down a healthy 757 RWHP and is just a blast to drive with the Circle D converter keeping it in the power band!

David got a hold of us because his supercharged van quit running and no one around him could figure it out.

So he shipped it to us all the way from California for us to diagnose and fix.

Turned out to have plugged cats.

Well he decided while it was here he wanted a cam, headers and muffler done on the van!

So we Installed a Brian Tooley Racing PDS Stage 1 Tq cam, New headers and Y-pipe, and a corsa muffler.

It laid down 465whp and for as big as it is this van rips!!

He flew in and drove it all the way home! Thanks again David for trusting us with this build!

We put a Brian Tooley Racing PDS Torque cam in this Supercharged Explorer van because why not!
