Chad,
Why didn't you go centrifugal? I know the old roots typically bring more low-end torque.......does the same apply to the whipple.
Or go turbo.....although plumbing and shared oil can be catastrophic.
Seems like the steady build of a centrifugal would be more useable in a traction limited small tire car.
Not shitting on anything......just asking.
Good job on the build.

Centrifugals are turbos with an identity crisis.
Turbos? What ISN'T turbo'd at a drag strip in 2020? It's just so normal now and gets to be pretty boring watching guys incinerate tranny fluid as they bump into a set of staging lights.
I've always had blower cars. For the last 20 years or so. I just like them.
Last, Whipples are PD blowers. They are not roots. There's a big difference there.
I've done a few things here for torque management. Things I'm not quite ready to divulge as the setup is not yet vetted/tested and some of it is new. Stuff I conjured up on my own.
The car is an IRS. A Strange Engineering 3rd member on a fabbed center section with G Force 3500hp rated outlaw axles. 25.3 cert on the car. The entire rear section is one of a kind. All tubes, all fabbed. AFCO's that have been revalved, the works.
I've also played with the injection some. This engine is GROSSLY over injected to the point of being absurd. There's a reason for it and I'm pretty confident it'll work to expectation. Chambers have been softened and the quench ring is down around -.110" from the deck height. Block is hard filled. K1 crank and rods from Callies. Athena gaskets with CA625 studs from ARP.
9.2:1. I could have gone more on the CR, but there's really no reason to with alchohol and this much headroom on the blower.
It'll just be easier this way as the motor is truly just to see what a top heavy blower will do in this setup. I made the entire blower drive from scratch. Pulleys, idler brackets, the works.
We stopped counting at 43 pieces that I made for this thing. -winters are long in S. Dakota, lol.
The car belonged to Chris Nichols. Chris was the founder and lead engineer at G Force Engineering. This car was his mule for exploring and vetting all of their track products. We became friends a few years back and he offered to sell the car last fall. The opportunity fast tracked the whole project by leaps and bounds.
It sputtered to life for the 1st time Thursday night. Just a few things left before we start testing.
Hoping for low 5's in the 8th mile and it should run low 8's in the quarter. Traction management will certainly be a real thing with this which is kind of the point with a small tire car. FWIW guys tonight were hitting 5.30's@around 135mph tonight at the track. Big tire cars were knocking down 4's.
Fingers crossed.
