I see. I thought you were saying 10:1 is too high for any FI setup.

Excellent! Yeah this is exactly what im leaning towards. I would even sacrifice a little power and do stock CR 11.0:1 to make a bad ass race gas map lol.

I was thinking about doing that but my engine builder can build me a dry sleeved piston and rod motor for half the price of a allen built 2.4. I would love to do that but I dont think it is necessary for my situation. How do you like the 2.4 boosted?! What are you revving out to?

I didnt say it cant be done, i'm saying its not the most reliable thing to do. There are far more blown up 500hp hondas than there are 500hp hondas that last a long time, especially if the owner beats on the cars like most of my customers do.
