So I was listening to Jake's radio show lastnight pt II of the Cylinder heads and power over 120 and up.
I heard him say 2270 makes power to 6 grand followed by 2056 with same heads will make power to 7 grand. So I am building a 2098 71mm stoke 97 mm pistons 10 to 1 compression Probably going to spring for the LE 200 heads Ok so Autocross course of late require me to spin to at least 6250 RPM or shift to next higher gear for that short 40 - 50 feet. Better to stay in lower gear and gut it out against the rev limiter Which is faster overall 2270 that will pull taller gear or accelerate quicker in lower gear but be limited in top speed by being all out by 6K RPM? making 60 MPH tops Or short stroke motor that will pull well with a ZD 3rd and can hit near 70 MPH I think there is more to discuss but I am somewhat distracted right now damn ADD. |
