Default Twin T70's + 408 preliminary #'s

After about a year or so from blowing the stock motor, we finally got Steve's car back to the dyno with a fresh engine.

Jeremy Formato came through (as always) with the tuning and we're all pleased with the results.

Without further delay, here they are:


For those that don't know, here are the details:

408 with Callies/Diamond internals
WCCH Edelbrock 245 heads
smallish grind Comp cam
Twin T70 huffers
96lb injectors w/ twin 255 pumps and meth injection

We had a mix of about 65% pump/35% 115 octane in the tank and ambient was about 100-102 degrees.

Hopefully we can try for more in a couple of weeks with straight race gas and cooler ambient temps.

Right you are, Jason. The "analog 1" is boost, scaled on the right.

It was originally the PTK kit, but, with the help of a few friends, we modified the kit's manifolds to accommodate T70 turbos. Additionally, we fabricated larger downpipes and charge piping. I guess at this point you could call it a 90% garage built set-up
