Sorry guys, lack of update.

Been busy with the race car prepping it as well as finish the customers work. Its more important to us.

The head was milled, and is being reassembled this coming week. The swap should begin in the following weeks. No new pics, as they would be the same as the pics earlier.

MOTOR IS COMPLETE!

Alright fellas, the motor is now complete. Fully assembled and blueprinted . Everything measured out precisely to how Jeremy likes it.

It will be about 2 weeks before i get the motor in and dyno'd. We are really busy at the shop so customers are our priority at the moment.

here are the final pics before i create a new thread on the DYNO #'s!!!








My valve cover is on the way from the powder coater. so these will be the final pics until it is in my car.

hope ya'll enjoyed everything.

instead of posting another topic with the dyno#... why dont you post them in here.
that way it will keep all the build up info and dyno# in the same area so it is easy to find

Now any guesses about RWHP? I'm going with ~255 at the wheels.

I did not realize compression was that high, so let me change my guess to ~265 at the wheels.

Adding 2points of CR will yield more then the +10WHP you added to your first guess.

I would guess around 285 for a 2.5ltr 13:1cr, headwork and supporting mods keeping the OEM intake plenum + a good tuned standalone.

Real question is, what will the final torque numbers be? Where will they drop off and how fast can you spin that sucker before you start getting ineffectual?

This motor would be a good candidate for FullRaces new manifold.
