ITS Ford Mustang(s) Build - Stripper Stang Part II

[Ron Earp]

Matlab code is up to Jeff G so he'll have to chime on on that. We do know this, the differences with the ratios are so close you'll never feel it. You'd have to have solid track data or simulation results to pick the best ratio, at least for our cars. I think a peaker motor would make it easier, but with a broad powerband it is difficult.

Hate I'm missing the Road Atlanta race this weekend but the Mustang Ranch is still in operation. As previously mentioned, Jeff G's motor developed a nasty tick after the ECR at VIR (2nd place finish, first wood for the red car, woo!). So we pulled the motor last weekend and tore it down last night and today. Thanks Flatout guys for the t-shirt catching oil. It was used up with a huge tear down the backside though and lived a happy life until the end.



These motors are quite involved to extract and take more time to tear down than an inline engine. Most everything looked pretty good on the heads, that is to say, they sealed up nicely (leak down and compression results very good but that was a week BEFORE the tick) although one or two cylinders on each side was a bit wet with oil.



Exhaust port #3 was fairly soaked.



Intake dry though. Sorry the picture sucks but you can see the port matching almost an inch in, and after that it was quite dry and just a bit of carbon fluff. These heads flow well without any work needed, which is good, since we can't do anything in IT anyhow. But they are a very different animals from a stock 5L V8 head if anyone here has experience with those.
