just dynoed my gsr yesterday. im slightly dissapointed i thought i would see better numbers . tell me what you think. pull was done in forth gear.

setup:
m22's
rocket valvetrain/flat faced valves
usdm itr pistons

blox intake mani.
64mm throttle body
cold air inake

I think you messed up the images tags, try redoing them so we can give you some feedback. nevermind looks like you fixed them.

Well yeah i agree, the numbers do seem low. I'm wondering why vtec doesn't seem to be providing the usual torque gain. What's the resulting compression ratio now?

 

yeh numbers do seem to be kind of low

 

sorry just learning how to post images. also edited forgot one important and superior piece my dtr b unit header. imo

 

compression some where around 11.5

 

the numbers are kinda low but take it to the track and time it. i remember my old set up similiar to yours but( ctr cams 11.1 cp)only made 158 hp to the wheeel @ Oshsimo and still ran a 14.4 on falken azenis in a fully interior dc2

 

How long have you had your m22/rm valvetrain? How do you like them with your setup? I'm trying to decide between those and the bc spec 3+.

 

well i thought the same thing when i first started my build over the winter bc3+ or m22. decided to go m22's for there good low/midrange power. they seem to be a good cam which is why i am disapointed on my #'s. not to mention it took 9 hours to tune and its still not right. the cams seem to be very picky. im actually trying find someone(in the east coast if anyone knows somebody) who may have better knowledge with the s200 tuning. ill be satisfied once i get the torque #'s up and the two dips in hp smoothed out.

 

Obviously something isn't right. M22's are actually the least "picky" cam that you can get. I have them in my car and LOVE them, and as far as comparing them to a BC3+, they will DOMINATE them from 7k plus. I'm willing to bet any amount of money it's not the motor's fault, maybe an assembly air or something? Have you done a compression test? And cel's or anything?

I'd bet money you are quite possibly wrong on the whole deal here. His setup is VERY similar to mine, and well, lets just say I was not impressed with M22's either. Here is the dyno, Skunk2 Stage 1's vs the M22's. You look at it and you tell me the M22's are better.



Just the facts here, not trying to bash anyone. This was done on the same dyno also, only things different between the two are the M22 cams, my own LIGHT cleanup of the head casting and a Hondata intake manifold. I tuned both, including the cam gears. These are the best results I could get.

who else has dyno sheets with m22's. plz post

 

Something is a miss... torque drops way off @4600rpm. Almost 15lbft drop from 4600rpm to 5100rpm.

How's the A/F ratio? This may give some hints on what is amiss.

Also are you absolutely sure that crossover is at 5800rpm?

One of my dynos, i cant find the 191whp one, ill look for it, i did over 100+dynos. This is my FIRST pull with b16a cams, the last is M22cams after tuning.
Gsr Block, PR3 Pitsons, B16 head , m22s, anr header, AEBS manifold
tuned with a VAFC


B16, STOCK BLOCK, STOCK HEAD, just M22s and a DC JDM 4-1 Header, AEBS manifold, Omnipower Valves


EDIT:**** , i forgot to switch it to SAE. well, subtract 3 whp from those numbers.
EDITx2: I also never even knew what my timing was at on the GSR CRX. I was tuning with a VAFC, and i had it at -25 in some spots. also i was dropping 12psi in fuel pressure in vtec cause my DX fuel pump was not up to the task. i never got to find out what it would have made with more fuel

 

thats way too low, find another tuner.. maybe you fucked up your head by the DIY port job

 

as i was talking with some people before, EVERY motor is different, i cannot stress this enough. for some reason, my GSR and that B16 liked it REALLY lean, like 14:1+ lean. no detonation ever occurred. some of the M22s motors liked it rich. my suggestion is to put it at 13.5:1 and go lean and see if it makes power, but look at the WHOLE graph. and see what it does

I have to redyno the B16 cause his injectors were showing 106% duty cycle, so i got some H22s to put in. ill have more numbers posted this weekend.

im thinkin it may be the DIY port job also..

problems it could be in no order

tuner

rings not seated yet(least likely)

diy port job..u can **** up a honda head big time if u dont know what yer doing

 

how did the cams do on 0,0??? i know rocket cams work very nicely w/out any adjustments

</TD></TR></TABLE> which is which, and if i recall, didn't you like your m22s?

I have NO idea who you are so I don't know how you could "Recall" anything I said. The red line is the stage 1 skunks, blue is M22's. I thought that would be obvious.

 

Two things I noticed.

A) The curve is very unhappy, it looks like the fuel trim is not very linear. Could just be the DynaPack also...

B) It seems to be peaking higher than the graph implies, so maybe there are more peak HP beyond what you were revving to.

I want proof before I believe that dyno graph that you have posted above, or did you ever consider that that motor dyno'd wasn't "big" enough for M22's?? I think you may be jumpin to some conclusions here. If the creator of this thread wants, I can post NUMEROUS thread on how much power the M22's are making....
