ChumpCar Racing

What was great about the engine build i that it is using all stock toyota 4age internals, hone was done using mix of Fat Tire beer and tranny fuild with a $40 auto parts stone hone tool, and the only mod is the air intake and air filter.
We have picture proof that Fat Tire was used as honing fluid. This is not a joke.

Very nice! motor looks healthy. What were these things rated stock, at the crank? I'm always scared to hone myself.

It was definitely a moment of tension for us, dynoing a car with like... 20 miles on it (the miles driven to the dyno)

I'm starting to think dyno break-ins are where it's at.

Also, interesting fact - Bill Caswell is driving for a team with a turbo Escort this weekend at The Rock in NC.

I have a feeling we'll be seeing lots of chumpy turbo setups this year...

Haha that's awesome that Fat Tire was used as a honing fluid! Looks like it's making pretty good power too. Hopefully it holds together for you guys.

A massive 112hp at the crank, haha! Shawn said he was on pins and needles while the car was on the dyno, but I think he's comfortable with it now.

People can build all the janky turbo setups they want, it's just one more failure waiting to happen that will give teams like us a better shot at winning. :)

This car is pure awesome.

I approve this message. Turbo setups are a increased liability even when done properly. I cannot imagine anything good coming out of a turbo car in a racing series already containing the keywords "Under $500 and Endurance."

Any idea what your setup weighs, Matt?

No idea. I hope Jeff The Alignment Guy is in good enough of a mood when we get it aligned to put it on the scales and weight it for us.

Ok. Here is a good baseline for you to reference against when you get around to it (from our street MK1) :

85 AW11 (with sway bars) a little wight reduction.

Jebus...sub 2200lbs and that hp, should be a fun track go-kart!

It handles like a go-kart, has about the same straight line acceleration as one, too. At Iowa Speedway we were SOL on the oval unless we were able to catch a draf (+5mph on the top end) but we did work on the infield road course.
