4.73@150mph in the 8th mile on a 275 tire. Woo Hoo.

Some friends kept blowing up a hub coupler on their ProCharger setup. I got asked to look at the part and see about making a new one.
Whittled a pair of em and the reward for the effort is they are the fastest car in the field during qualifying and are currently in 1st at the Edelbrock Extreme Street event up in Michigan this weekend.

Fun part to make.

Chad are you racing at Martin Speedway?

Its so nice to see one of our own leave the nest and succeed in the real world......and here I thought everyone was just sitting in Moms basement with the Fleshlight.........

Don’t you worry PM, me and plenty of others here will not fail to meet or exceed your low expectations.

In any race to the bottom, I will always take Pole Position.

That’s insane what’s capable on skinny radials these days. Funny to contrast that with the late 80s pro street fairground cruisers with 18” Mickey Thompson’s.

Holy fuck, that is some serious shit right there, congrats. But my question is, why on 275s? Were they enough for good traction?

I’ll let Chad speak for himself, but I don’t even have a basement. But, don’t cry for me, Argentina. I’m gettin’ it done in the garage...

What , no vid ?

What type of car and motor to launch on 275's that hard?

Nice! In high school and college I used to whittle some aluminum to earn free machine time to keep my race bikes tricked out and working. One of the shops clients was a fwd drag team. They were pushing over 900hp from a 2.2L Prelude motor. The problem was cylinder pressures were so high the cylinders would expand into the water jacket and it would lose compression. I made a series of aluminum plates to press into the water jacket and around the cylinder. It worked and they they took the fwd title that year. I don’t remember the times they were running but it was 8-something I think in the quarter.

There's a vid clip in this FB post of the car making a pass. I'm not a FB ninja so it'll prolly require some stupid friend request or something for everyone to see it.





That'll do!

Most of the "street" classes limit you to a 275 per the rules. Trying to keep some semblance of "street" after all the guys started showing up with "street" cars that were really pro-mods.

Longrifles - props to you and your skills. Best of luck to that team.

Class rules. The original intention was to slow cars down with a small tire, and take emphasis away from pure horsepower. The racers didn't get the memo

It's the class they run. 275's keep the setup and class "honest" in the sense that trying to solve the ET challenge with cubic dollars isn't necessarily the best pathway. One only gets to put so much hate to the rubber.

The loophole these guys are exploiting is the overall weight restrictions. With a smaller engine the requirement to fatten up the car with lead is avoided. To make up the power lost from the smaller engine, you start running boost levels into the "ludicrous" region of atmospheres. (48 or so psi or 3.3bar) That is what was prompting the part failure that I redesigned. The cast piece was just never meant to work the blower that hard.

So far, the strategy is working and that's pretty cool in my book. These guys came out of the gate with this thing switched on full auto and they backed it up all weekend.
