well the day of reckoning finally came. fininshed up the tuning and and got her dynoed. i tuned with crome. the results are well, ehhh. i lowballed my estimates because we all know too well how devastating real HP numbers can be after all the time sweat and money poured into our rides. at the very worst i was expecting 170whp considering a few issues earlier on. but my real goal was 180whp. mods are RMF header, AEMV2, carsound hiflow 2.5 cat, greddy evo2, chipped ecu, crome tuned.
all pulls 4th gear not to happy with the results but not completely terrible either, just expected more.
here is baseline:



final pull:

 

that header is designed for work with a lot of internal block and head work so don't be sad.

 

yeah its def designed for a even mildly cammed engine but thought it would pull out some more on a stock block. oh well. cams here i come. thinking of going with skunk2 stg1 for a nice mild cam. daily driver.

 

Have you ever compression tested your motor? Those numbers are what the motor should be making stock! And just to make sure, this is a h22 right?

 

yep. A good cam setup and higher compression - and you'll be in there.

The numbers still do seem kinda low though.

 

h22, and yes compression tested before dynoing. all within 220-235

 

the gap should be 5-10 psi each cylinder. Something doesnt seem right. Those numbers are really low.

how do you mean?? 220-225-230-235 like that or from only a gap of 5-10 between them all like 220-220-230-235??

 

Yea your comp numbers are good, i was talking about the whp numbers though. It just isnt adding up.

 

oh. yeah i hear ya. im a little disappointed. only thing i can think of is a bad tune. which i was told in another forum. but he seemed to know his stuff or i just happened to have started with a weaker engine. i have seen graphs of stock or mild ludes putting out as low as 150-160 whp so i dont know. how many graphs of RMF'ed h22's on a stock engine are there??

Not much, but regardless, their header is well designed. Ive seen graphs of SMSP header, on a stock JDM h22, making 200whp. SMSP and RMF are both well designed and their gains should bge similar. I dont get it.

 

i dont get it either, healthy engine at least relatively. dont know why such low numbers im hoping i can open up the potetnital of this header with a mild cam.

 

get me those bin's bitch

 

HAHAH there he is. i emailed him last nite i think i'll just call him. he is actually a member on here and talked to john to get the bin for my basemap i got from phearable. the only thing i noticed on the graph was a dip after vtec where it got a little rich. he did smooth it out at least a little from the basline run

well...it's not well tuned..look a your A/F graf...a traced a line in 13..start downs(12.6)..goes up(13.5)...then goes down(12.8)..goes up and it stays up(13.4)....well my friend...it's bad tuned...should be 13~1

look a this link...look a/f in this dyno sheet...that's how your should look like...it's the blue line...https://honda-tech.com/zerothread?id=1530692

when you correct that...you will be happy....another thing...most guys that have other companies headers(smsp, hytech,SSR etc)...have a good 2.5 exhaust and muffler...euro r intake manifold...o ported stock manifold...don't have hi flow cats...what i'm trying to say..the have a good intake and exhaust system that can maximaze their engine...

you can't just expect a miracle just bolting a header and have a crappy tune...sorry...

 

i prolly have the bin that john used on my computer. But the basemap is not what i am concerned with.

 

Well doggone, I can't see the tune here at work.

I want to say the a/f doesn't sound like it would give as big of a loss as you guys are making it out to be, so I'm going to say check the timing tables and see what kind of spark advance you're getting in VTEC.

just saying that's not well tuned...nobody is making a big sh*t about it...he gained 8hp and 7tq peak with a crappy a/f ratio...

he needs to get well tuned...and a better exhaust system...then dyno...

 

That air fuel looks pretty good. Thanks for posting your results!

 

i dont see whats wrong with the xhasut system. granted it could be better, its not a true 2.5in exhuast but its not terrible either.

 

hmmm....

i have to agree with him on this one. BUT....
close setup, with stock block
euro-r im, stock tb, head built, smsp header, a'pexi intake, 2.5 cat, no tune!!!!!!!!! power-fc running 440/cc min-
made 194whp baseline- REALLY DAMN RICH!!!
WE are talking.....tooo muccchhh damn fuel!!!
figured out from dyno baseline, just a flat curve, even in vtec were it stumbles due to fuel.

hope you get your car tuned (especially during the vtec crossover where it goes rich) and the results are better.
good luck!

thats what i want to look at when he sends me the bin.

 

dude my h22 is stock inside, and with a 60mm catback, no cat, rmf header, and j's racing style intake, i put down 183whp on the rlz dynapack, which dynoes stock h22s at like 135-145....

your numbers are very low, whether it be your tune that is making the whole difference or something else, you are missing at least 10-15whp.....

on the tq side, i put down 141....and my line was a good bit flatter than yours.....remember that the dynapack reads very low....that should be somewhere around 155-160 dynojet....but i have yet to hit one....

that was with power steering on there too....

is it a usdm or jdm h22??

 

^^usdm h22a4.

 

them fighting words

baseline run was with all mods UNTUNED right? well just think of this, maybe you would have made only 155-160 with stock header.
