Cold sunday night, roughly 40 deg. took my car out and did a few pulls top of 3rd gear and it felt faster than ever. Reached down and pressed my peak button my defi gauge to see how much boost I hit .....
and for all of you that don't want to do the metrics
thats 19.1 lbs of boost remember this is a stock h22
luck. pure luck. I wonder if your gauge is broken :P or the wastegate bled it all? btw is your setup legal in your state?
I've crept to 1.2 about 10 times .. I think its the wastegate is to small but the aem ems is tuned boost comp closed loop and I have a stock honda map sensor so as soon as it hits 12psi it just does full duty cycle on the 750cc injectors. I'm sure thats why its still alive
creep huh??? when installing my tial wastegate w/ a 7psi spring the washers on the fittings, the ones that go to atmosphere and turbo, in the wrong order doubled up on oneside ( yea that sounds dumb but my friend put the wastegate together figuring that you really cant mess that up...but he did... i actually at wot i hit 10.5 psi in third..... and i didnt blow my motor. then 4 times later... the ringlands didnt wanna hold up anymore. moral of the story just check your wastegate if you worried about killing your motor.

I did'nt use those fittings. My vac line is braided a/n screwed in with teflon tape wrapped around the threads. It's installed properly I'm not concerned about my motor blowing. I have a good tune 19psi is rediculous. I've been daily driving the car on 9-12 psi
I dont find this believeable, especially being tuned on an AEM EMS. but whatever. 19psi is rediculous, something is wrong somewhere. Your guage could be bad, its not impossible. An H22 would grenade under 19psi on stock internals, certainly if you did it more than once. 14-15 is more believable.
Seriously, the H22 has gotten a bad rep, mostly from situations where the motor has blown up to poor setups and/or poor tuning. H22 pistons aren't any weaker than other OEM Honda pistons.
i've heard that the defi boost gauge tends to read higher at times then the actual boost...i was looking into getting these gauges but when i heard this i wanted to see first..ludetech have you ever had this issue?? my source by the way is al (dynoflash) friedman he's real big in the evo community...i dont know let me know man
^^^defi gauges are some of the most accurate gauges in the world. This gauge reads the same boost as my aem ems. I know for a fact that the motor would handle this amount of boost with the right air fuel mixture and timing. Ludegirl I don't mean to be rude but you really just don't know enough about programable fuel injection/tuning/ and the overal ergonomics of the honda motor if you don't think the motor could handle 19psi multiple times. It can handle it if you are not holding 19psi from 5200 to redline on a 5th gear pull and egt's are climbing. I keep fuking saying the same thing over and over. Your motor will hold if you keep heat down, keep a good tune in her and do some godam preventative maintance. Its getting old, I've said it hundreds of times it never seems to click in with some people.
Ludetech, Im sorry but I think you're wrong. NO STOCK HONDA ROD can take the abuse of 19 psi. period. no matter how good the tune is. Its not the tune, its the force on the rods.
A perfect tune on Hondata or Neptune wouldnt even keep that motor together under 19psi, AEMEMS cant touch them IMO. I've been tuning for a few years and have never heard of something so asinine, nor would I reccommend what you're doing.
5th gear pulls are never a good idea, and neither is running 19 psi on stock internals at any RPM. I could see it happening once or twice when you are experianceing a quick spike, but why would you keep doing it if you knew of the problem? Fix your problem. I dont think that motor will last you too much longer. You're lucky enough.
Maintainance has nothing to do with 19psi on stock internals. LOL.

yes it can, the rsx motor matt tuned did 523whp on stock internals multiple times

Matt at onefab did 22psi on stock internals for almost a full season. Ran 10.6 multiple times tuned neptune top mount gt40
Matt at onefab made 446whp at 18psi and ran it multiple times at the track. Thats a solid 18psi, not a creap.

Actualy I don't drive the car much but when I do I drive it hard. It's never spiked this hard before and it's only done this twice. It's because of the severe cold. 38 degrees + 60mph on the freeway for 30 minutes = rediculous 3rd gear pulls.

if your short a quart of oil? yes it does. If your low on compression, yes it does. Thats the difference between a motor that is about to pop then you push it to the limit? yes you will explode.

Boost pressure doesn't always correlate to cylinder pressure. Detonation and pre-ignition will raise cylinder pressures to danger levels for the rods. 19psi of boost won't.

correct. The rods/ring lands won't hold detonation. They will hold 19psi. If yours wont then your not tuning properly

Again, you are talking about intake manifold pressure, which has very little to do with the subject. It's about fuel, ignition timing, sufficient lubrication, and power output, not PSI; e.g., are we talking about 19 psi from a straight T3, or an SC61?

I'm on an sc-61 57 trim .60/ar cold side .63 hot side,
and btw who is turboludegirl I've never even heard of her
.. I think its the wastegate is to small but the aem ems is tuned boost comp closed loop and I have a stock honda map sensor so as soon as it hits 12psi it just does full duty cycle on the 750cc injectors. I'm sure thats why its still alive
