ok i went to the dyno again i and i was not thoughly impressed. i put down 222hp and 168 ft/lbs. i really thought it should be quite a bit higher, i am trying to get up to about 240. right now i am trying to see what i might be able to alter to see if i can get the gains i want. here is a list of mods.

h22 bore to 2257cc
12.8-13.1 compression
endyn rollerwaves teflon and moly coated.
head is bored to match
p&p head with ferrea full valve train .5mm oversized valves
skunk2 stage 2 cams
cam gears
440cc injectors, peak and hold
aem ems
aem ugo
twm 50mm tb's
hondata intake gasket
header-tech header 4-1 with 2.5 inch to 3" outlet
3" exhaust w/ catco cat
lightened crank pulley
pro-drive oil gears
act prolight flywheel
clutchmaster clutch
bearing clearances at 1.9 thou.
eagle rods
balancing shafts removed
cometic gasket o-ringed block


i have a feeling that the manifold is a little too much. i would like to try my stock head as well and i would like to try my stock manifold too. also maybe my oversized valves caused me to have to turn my cam gears out 5 degrees retarded on the ex. and 3 on the intake from centerline for valve to valve clearance.

what do you guys think. i would like to look at hp numbers and dyno charts as well. and let mew know what your fully built all motors are making. my compression test was 220-230psi with this set-up. i would like to compare these as well to other h22 with these cams and close to this compression.

iwas also wondering if anyone has experiance with the rollerwaves in a the h22. when i cc'ed the piston in the motor to check valve to piston clearance the head was really far from the piston. like they really arent 11cc like laRRY SAID. i wonder if i got the wrong pistons. this is why io want to compare the cranking pressure.

please feel free to comment

 

seems like good numbers but ive alway thought that 50mm was too big for the power band of an h22...im no great bulider but just a feeling i have ....i think you got great mods done but theres stil more in there

i remember way back you though the head might be ported wrong but you bought it that way this was a long way back )
mabye try a stock head just to see what you lose/gain mabey

 

yea it should be making more.. we made alot more with alot less parts.. waaay less.. keep trying.. or send it to someone who can get the power you want for you..

 

Fucked Up Cam Timing...also, theres no way that 220psi cold crank is 13:1.

 

yea thats what i was thinking. i wonder too if the endyn cf manifold is ready yet. they have been waiting for like a year.

and the cam timing is pretty far off too, but it wont give me the crankpressure that it is supposed to be.

 

Here's my old setup before it blew up. It made 212 whp and 139 on a Mustang Dyno. Tuned with Apex Power FC. Daily Driven.

1.8L B18C
JE 81.5mm 12.5 c/r off the shelf pistons
Crower Econo Rods
RS knife edged and balanced crank
JG Pro Series all motor head B16a
Skunk2 Stage 2 cams
TWM 50mm ITBs
CTR crank pulley
Toda race header

Thats all I remember...

 

thats a really nice set up and it made the same power as mine prob. mine was tuned on a dynojet. i like the realatively easy straight forward build.

My stock JDM H22 cranked out 220psi compression.

 

so what your telling everyone is that your motor only makes about 185 hp because there is a 15% difference between a mustang dyno and a dyno jet? with that setup you should of made a whole lot more power!

 

thanks for all the replies and help. i talked to larry at endyn and it looks like we are going to mill the head and raise compression to 14.25. 94 octane and aem ems should prove this compression on a street motor. larry said that there will be no problems with detonation. he is pumping 330psi on crank and he runs 93 w/ no problems.

 

mustang reads lower than a dynojet. it is not a set number or percentage either. on average i have heared about 10 hp difference. so his engine in real world terms put down about 222hp, if he was on a dynojet i mean.

i know my engine was a 5 hp difference between the 2 dynos.

 

My first 2.0 was 13.0cr and only pumped 220 ish on the Cr gauge as well, i was running toda b's at the time. It put down 220 whp 154 tq. with partial fuel tunning.

My current motor puts out 238whp 163 tq corrected. 251 whp 173 uncorrected in 60 deg weather. You can find it in my sig.

 

our last motor was a stroker B16, with ITBs, and approx 15:1....i would hit 300psi on the guage by the 3rd pump

our current motor is a stroker GSR, with the same ITBs, and approx 15:1 again, and the same thing...by the 3rd pump, over 300psi on the guage....it dynos 240whp/172tq

ok what are you guys running in crank pressure, or highest crankpreaaure seen on pump gas.

see i have 2 different things going on here. Tbone knows tom payn and i know him as well. i trust his skill and knowledge, but i am still undecided on what to do here.

tom says stay with 222 and 168 and be happy. i said i want to hit 240 on pump gas. 220 psi is not that much if you ask me. that is probably around 11.5 comp. but according to endyn my compression is at 13.1. larry wants to mill my head 30 thou. and raiser it up to 14.1 or so.

i really do not think my compression is at 13:1. tom says that he wont go above what i am at for street motor (thi9nking 11.5). larry says mill it. what do you think? if in fact i mill it and it starts detonating than i have to just get a thicker head gasket. but what if it detonates on the dyno and it cranks a rinig or something like that. than i have to go higher

anyoine ever cc the rollerwaves? larry said 11cc is where that are. i find that hard to believe, especially with 220 psi.

bottom line is would you go above 220 psi on pump gas???

 

11 cc domes!! Thats HUGE. You have any pics? Those will make super dupers look small then, unless the just have really shallow valve pockets.

Edit 11 cc is huge for b series. i keep forgetting its h.. I did a cr on a b16 with a milled head and 2layer gasket the other day and hit 220. It's weird that my first 2.0 was only hitting 220 and putting 220whp down with no real tunning.

weird... i'm hittin 220psi on my 10.6:1 d16

are you testing with the throttle open or closed?

 

i think your low compression has to do with the oversized valves and cam timing. I've seen motors with higher compression pistons and larger valves put out lower compression and whp then stock motors. you'll probably need more compression to compensate for the valves, or switch back to stock valves

 

Hasn't it been proven that oversize valves hurt NA hp? At least to a degree that both sides of the debate have a leg to stand on...

although I'm far from an expert on the subject... Wouldn't those big *** 50mm ITB's be better suited to a higher cr and more aggressive cams? Mill the head, clay it and think about some bigger bumpsticks...

Just my 2 cents... If it's any consolation I'd say you're doing pretty damn good already with the 222whp... that's nothing to scoff at...

 

im have an h22 with 52mm itb's, skunk2 stage 2 cams, alaniz street port head and the ericks racing header on a stock jdm h22 block and i made 245.6 whp with a hondata s100 ......i dont think those itbs are too big at all.....they're perfect..........

 

ok thats hard to believe. what is your comoression you figure? are you running pump gas? what was your psi cranking?

 

we did the tunning at pro street imports on vp 103 unleaded. im not too sure on what the compression is but im guessing its somewhere in the 11.1 - 11.5 range.... joe milled the head about .20 and used supertech flat valves to bring the compression up from stock...... ill post up our dyno sheet when i get the scanner running........ peace

 

Here's another plot for reference, this is Jeff at Ib's personal motor.

 

Yah those numbers arent that big with your compression and the itb's I think my numbers will be around yours with my new header. Also my cam timing was off and I got low comp numbers from my pistons then I got it tuned and it changed so that might be the problem. Hopefully you figure it out because that thing should hit at least 240 or 250.
