my h22 was dyno tuned yesterday(7.21.06) and the outcome was only a whooping 160whp and 1xx lbs trq. we did compression test and it was 180,180,180,190. there are no leaks whatsoever. we advanced and retard timing and still no improvements on hp. even opened butterflies
here are my mods:...(tuned by st00pid)
98 h22a4 86k miles(stock bottom end)5spd manual----what can be wrong?? take a look

-Port n Polish, 5 angle valve job (by westside performance)
-crower stage II camshafts (stock idle)
-skunk2 proseries cam gears
-rocket motorsport full valvetrain, *dual valve spring, titanium retainer*
-(stock valves)
-arp headstud
-h23 manaul tens. conv.
-BDL fuel rail
-AEM fuel pressure reg.
-RC 370cc injectors
-prospeed 4-1 race header
-AEM cold air intake(stock intake manifold)
-tanabe hyper medallion exhaust(w/ gutted cat)
-ngk spark plug wires w/ ngk iridium spk plugs
-UR racing SS pulley kit
-p28, obd1 tuned with hondata s200
-walbro 255 fuel pump
....POS. any info why the # is soo weak, i greatly appreciate it.

 

Yikes....you're sure your cam timing is dead on?

 

What did St00pid say about the #'s?

Anything done on the bottom end?

 

No..

Ouch man.. that's not right. You're losing power, the other mods are just making up for it. Not sure what it could be, I'd have to take a look.. which I can't.

 

yea timing is dead on.
"98 h22a4 86k miles(stock bottom end)5spd manual-"

 

i'm gonna be an idiot and ask are you sure your not firing off a cylinder?

 

make sure the secondaries in the intake manifold are either left always open or you use a nitrous out from the hondata to open them....

that still shouldnt be holding up that much hp....try taking the cat off and dynoing it open header, see what happens, maybe somethings clogged in there...

oh and be sure that the clutch isnt slipping

 

they rest open unless connected to the vacuum, as for your car making no power... is your cam timing set properly? if not that also may be throwing off your spark time unless you set it for adjusted cam timing, but yea those number look extremely low, does the car feel quick at all?

 

sounds like your compression numbers are pretty low to me. are your valves seating properly? as far as the crowerII's, are they the turbo cams? i thought those had a good amount of duration and i guess if the cam angles are off, you could be losing power during valve overlap? just a thought.

what the hell kind of dyno graph is that? HP vs. speed? how the hell is that accurate? you would have to be recording from like second to fourth. seems really fishy. and i swear, i dont know if this is a second thread you wrote but i know ive read a similar post and the tuner (stoopid) was brought up in that one too.

so what are guys saying??? put 2 n 2 together common factor = stOOpid??? i have heard great things about him, but havent used him.

 

just a thought, and it wasnt even the first. i know i have heard almost the same story before.

 

st00pid is a pretty compentent tuner, your compression numbers seem about right and are solid across the board..

i mean what kind of numbers were you expecting? did jason say anthing to think he was having tuning problems?

i would do a leak down test and see what numbers you come up with ,,

 

i would agree with a leakdown...sounds like the valves arent seating or something, you should be putting down pretty good amount of power

 

could it just be a crappy port/polish job?

not if just the head is P&P, maybe over polishing on the intake manifold but even then, he missing about 40hp and that doesnt seem right.

this was my first thought.

i have a friend with the 1.8T jetta who was tuning his car after some mods and came to find out he had lost power on the dyno......it ended up being his clutch

 

-all cylinders are good
-taking the cat off wouldnt gain me 40hp
-i have brand new exedy stage 2 clutch and kaiten flywheel..
-this is the same thread. i made a new one for it to be fresh.
...right now im thinking valves arent seated correctly..

 

get the leakdown test done and let us know what happens.

this crossed my mind too.

u can usually tell when a cat is clogged. It will glow red in most cases. But if it were actually clogged, you would be suprised at what power loss you would end up with.

could be a combination of things, not all dyno's read the same....but your numbers are low for even a dyno that reads low.

 

sometimes pieces of the cat can break apart and get lodged in there sideways...its like a wide honeycomb in there, air wont flow through if its sideways. you can def lose 40 hp if theres that much restriction

im interested to hear what you find from the leakdown test

 

Check to make sure the cams are tdc in relation to the crank pulley and flywheel.

The compression looks a bit low for a stock h22....

 

you can drill a hole in front of your cataylitic converter and see if
it frees up some hp, It'll sound funny though and you might want to
have a welder on hand

 

cams are tdc. i would think that since my head is not milled that would be the reason for low compression #

u head not being milled has nothing to do with anything, a stock usdm h22 usually has compression results 200+, its not that far off and all within 10% but still....when you said no leaks did u say that because u did a leakdown test or because compression #'s seemed ok??? even with compression numbers being ok (maybe a little low...) a leakdown test could show a problem even when compression is fine, so if you havent done an actual leakdown test do it

i dunno if what he modified from his original post but the ppl saying his cat is clogged, its gutted!!!!
