No one appreciates the implications of how something like this can be setup for a small motor street car?

This car is full interior, and a heavy pig at that.

Just has a harness for the driver, stock seats all around and a cage.

it's pretty bad ass to go 9.70's on e85.

There is a ton left in that setup. That HX52 is the same turbo I have on the race car, and he is on the wastegates at 37psi, The HX52 as a big single will support boost into the 60s with E85 and conservative timing.

For perspective, there are a ton of Turbo V8's both carb and EFI that make the switch from 116oct race gas to E85 pump and pick up significant power, thats how stable the E85 is.

E85 is one my favorite fuels, by a long shot

You should see the power people pickup when they can get aggressive with the timing at high boost.

I bet my 2008 stock Fit Sport could keep up, on unleaded..
