R/S Ratio??

[Fearit22]

I always hear a lot of talk about rod stroke ratios and how important they are to high revving engines, and I was wondering what is the "ideal" ratio. Would it be the same for all engines or would it differ? What is the r/s ratio for the f22?

i can't remember so i'll have to research the answer for that question...maybe someone will beat me to it tho

Would it be worth it to destroke the f22? Couldn't I balance the lost displacement with an overbore?

Well I'm not sure how high I would need to rev exactly. I have the valvetrain components pretty much planned out and I think everything else would be good for revs up to 10k or so they claim. I just want to be able to boost to around 15 psi. I'm not sure what kind of lag I will get or how high the turbo would be efficient so I was hoping to have as long of a powerband as possible. I don't want something that would spool up at 4k and not be able to rev over 6k since that would be pretty worthless.

actually even if it doesnt spool till 4k thats only in first gear when you are at the track if you shift fast enough when you hit second gear you will be back at full boost in like 500 rpm boost doesnt always just go away every time you shift it just gets lowered a little.

only if u take ur foot off the gas lol...Disclaimer: Don't try this at home kids

yes thats true the allmight powershift will allow you to never llose boost. hondata has a special rev limiter that when you are shifting you never have to take your foot off the gas which is pretty cool but hell on trannys.
