K series guys ( well mainly gregg lol)

no offense mike but I'm a little skeptical of this 300whp number. making 300whp requires a certain amount of wtq at a certain rpm. so take your pick:

300whp = 210wtq @ 7500
300whp = 196wtq @ 8000
300whp = 185wtq @ 8500
300whp = 175wtq @ 9000

looking at those numbers it is obvious that the easiest way to make 300whp with a honda is to rev it to 9k and still be making at least 175wtq at that rpm. But when stroke, rod length, or compression are changed... the cam requirement of the engine is changed also. I guess what I'm trying to say is don't expect a cam that makes 250whp on a stock stroke, to be worth a damn on a bottom end with different geometry, no matter how awesome the bottom end is, you might only see 5-10whp. I also hope you aren't planning on the 196wtq @ 8000 route... because that would be more VE than a cammed K20, and with a longer stroke that is pretty much impossible.

So on a legit dyno jet, I think 270-280whp from an H is pretty feasible. but just like 1/4 mile times, every little bit is more and more difficult to achieve. I'd expect it to take a perfect cam for the application, 13:1 or higher, proper fuel like Q16, perfect header and intake manifold, all dialed in... and at least 2.4L to have an H make 300whp. the only reason I say that is because it takes many of those same things to have a K make a legit 300whp, and I would expect the H to be a little more difficult due to the head design.

I hate to say "I TOLD YOU SO" but remember when i said something a few months ago and all the midnight guys jumped all over me. it was something like

No B Series makes over 250
No H Series makes over 270

K series are making over 300 in simple builds.

There are maybe 10 or less motors that have eclipsed the 300whp mark in a B Series in the history of their engines. There are maybe 10-20 cars making that power with an H Series.

There are probably 100+ making over 300 with a K Series.

Look at the local cars. Matt making over 300whp, Gregg was knocking on 300whp (no pun intended), Midnight claims over 300 or right next to it. There isnt a B Series in GA right now that can prove they make over 230. There isnt an H making over Jones 252, and i would venture to say besides his there prob isnt one making over 240.

Speaking of 250whp B Series, its september, wheres that motor at? still waiting on a clutch

My motor will make over 200 tq and it is 13.1 or higher plus im not running the same cam thats in my dads motor . I bought pro 3s . It is also a 2.4 litre so thanks for the recipe i think i already have everything lol.

On a serious note it is a goal but i will be very closs to it . My motor is a good but bigger then my dads with more compression , more stroke , bigger cams and h2b . If most h2bs make 20hp more and my dads car is running a h tranny whant number you think it would put up with a h2b mosely ? Im sure it wouldnt be twenty hp more but even ten more hp would be nice with better gearing . Ive done all the math and i have the shit to do it with so we will see what it does. The only thing i dont have is the money for a custom header which i need so im going with logistic motorsports and if it doesnt do what i want ill change that up. Everything else i have . i would like to go with 90mm pistons but im ready to get this thing done and have a spare sleeved block so for now it will be 88mm.
