Anybody know how much CFM@28" H2O the stock SRT-4 head flows? Also looking for the rod lenth. Thanks!

This is the link I found for the NA motor. I couldn't find much for the turbo charged version

I hope it helps some.

Hmm a 101mm stroke and 151mm rod length. 1.49 ratio... that explains the low redline. Would be cool if you could raise the head about 20mm with a deckplate and correspondingly longer rods and get that RS ratio to around 1.69. Then you could spin to 10k without having to worry about throwing a rod through the side of the cylinder wall

i have a friend running very close to that rod ratio and he spins his .4 turbo to 7-7500rpm no prob :twisted: :wink:
