Hey guys,
ive got a p13 with a mugen program chip, which was supposed to raise the rev limiter to 9500 but only took it to 8500. I was wondering if anyone knows a better chip that would raise the rev limiter to that rpm? Hondata s3?

Also, what cam timing is everyone running with the skunk s2 cams? not trying to shortcut tuning, just wondering what everyone is running. What kind of numbers are you getting also. midrange, top end?

 

there is no reason to rev that high, 8500 is pushing it as it is with the h22 motor, unless you have seriously built bottem end and some crazy valves, retainers, springs and cams then why rev that high, this isn't a type R motor is a huge stroke h22 . if you really want to rev that high then you would have to get some other stand alone, and even if you do get the engine reving that fast is only going to be there for a second before you float a valve or spin a main bearing. all in all not a great idea. and there isn't any power to be made that high. look at mostly any dyno of a h22 and the power starts falling of past 7 grand

 

from what i hear you start to spin bearings when you rev that high in the h series motors

 

lol buddy say goodbye to your motor. you don't even make power at 8500rpms why the hell would you want to raise your rev limiter.

 

skunk2 h22 dyno inside
https://honda-tech.com/zerothread?id=637095

peak power is 7,200ish after that power goes down.

but i believe he should be pushing more power with what he has, but still pass 8 is craaaaaaaaazy!

 

I don;t think that one counts...he totally fucked up his intake manifold.

 

Yeah man there is no reason to rev that high and most
of those chips (mugen etc) will do you no good

 

well i do have a fully built head but i was told not over 9000 on the stock bottom end. If i want to take it over 9000 i need bearings (BTW RECOMENDATIONS?)
Not only does my car pull the hardest before it bounces off the rev limiter, but i AM going to build my motor more before i take it to 9500.
ie type s piston, milled .020, and better bearings which im still looking for. but other then that i feel confident that im not going to blow the motor going to 8500.
Im getting it dynoed this weekend, and i expect around 210-220
mods are.
Skunk2 s2 cams, valves, springs, ret, gears, cometics head gasket, 11# flywheel, 3'' intake, kamikaze headers, exhaust
after this winter im adding the pistons and workin the head.

 

Hit the dyno and post it up, really doubt you are making peak power at rev limiter. My Crower Stage cams peaked at 7500, now thw skunk2 should be higher, but not likt 8500 higher. You can't fight against the stroke of the motor.

 

even fully built. you won't need to rev that hight. i have seen but one dyno of an h series peaking it's power after 8k. that was fullllllllly built 12.3 compression and itb's. one out of a million that i've seen make more power. he peaked at 8100 rpm. trust me. 8500 is the limit. i would neeeeeeeeeeeeeever take it any higher. i want to. but reality sets in. i wish i had the graph to show everyone. i think it was posted here or over at po. it's quite impressive. torque peaks at 6200rpms and just holds all the way to 8500 when he shut down.now that is tuning. also to mention that that motor was no daily driver by any means.

so now ask yourself. why the hell would you rap it out to 9500rpms? sure it looks cool and probably sounds cool. but it isn't helping you performance wise. so why do it?

unless you accidentally downshift...lol
just givin you **** Brian
to the guy looking for bearings,
OEM is the best

 

"torque peaks at 6200rpms and just holds all the way to 8500 when he shut down"

Ive gotta see that, what setup if yout know...that is f-in impressive

"really doubt you are making peak power at rev limiter"

Ok, well now that i feel for it it seems to drop off after 8, but it still pulls till then im sure. BUT like you said, im going to hit the dyno and ill post results soon after.
My GOAL was to have a tuned motor to rev and pull to 9000 or more. I mean if this is not possible, you know thats one thing, but im mainly trying to get top end power

 

i'm not sure of the guy's exact mods. what i do know is he's at 12.3:1 compression. skunk2 everything. TWM itb's. etc. etc. it didn't actually hold it's peak torque it went from 176@6200rpm to 168@8500rpm. i don't know where the graph was. like i said. it's on here or po.

 

if you wanna rev past 9 buy an s2000 and start working on that

 

explain the differences in the motor to me then? your gonna say that the h22 isnt made for reving high..why? explain to me why you think the f20c is so much different then a h22 (anyhting that cant be changed)

H22a stroke = 90.7mm
H22a Rod/Stroke = 1.58

F20C Strok = 85mm
F20C Rod/Stroke = 1.82

That's pretty much it in a nutshell. The 85mm crank makes peak power/efficiency at a higher rpm, and the rod stroke makes it a high revving motor. A little too high if you ask me

 

lol, at least someone knows their ****.
good show..i take it there isnt a way of shanging that short of a new crank, block, and rods eh?

 

yeah i would say around 8k iws where the power stops

ah joel with the R/s ratio. i really don't see a reason for you to make a motor that would peak that high, i mean image even if you do build the motor to withstand the revs of 9k+ think of how long its going to take you to et there and to reach peak power, and then what happens when you shift your going to fall out of you tourque band, this is why the stock h22 tranny is setup withthe gear ratios it has, so that when you hit redline you shift and fall right back into the begining of the peak of the tourque curve,

joel is right, you driving a long stroke motor, the h series have one of the longest stroke out of all hondas except the 97mm accord motor. you just can't fight physics. the h22 is designed to get the heavy *** prelude moving. its doable to rev as high as you want but, its going to be ALOT of money, and one day your gonna spin a bearing just like every person who pushes a large storke motor past its limits.
