I spoke with Ted at Golden Eagle the other day and ran through a list of services they provide for engine blocks. He told me that the engine they would build for me would come with a compression ratio of 10:1 using a flat Arias piston. I was kind of shocked because I hear most people using lower ratios like 9:1 or even 8:5:1 with turbo hondas, but he said if I want a lower ratio than that, I would have to pay extra for pistons that are dished inward. He also said that a street/track car should have a higher CR or there will be too much lag. According to him, with a 10:1 CR on an H22 properly built, you can run 35psi..
which would put you somewhere in the 600whp range with the block alone, not including a ported head. Not that I plan on using that much power at this point, I'll probably be boosting at max 20psi with the proper fuel manegement.
What kind of fuel would be needed to run 35psi and 20psi with a 10:1 cr? also, how much will I be able to boost on pump gas with say 850cc injectors and an AEM ems?
Hope this isn't too off topic...
