It appears to me that a lot of people have blown rings, bent valves, melted pistons...who knows what. Somebody has done something to their motor to kill it with some sort of FI. I was wondering who had one of these awful things happen and why. A kind of warning to people going FI and what not to do. I know the topic is hard one to deal with *sniff* but we'd appreciate your input. Also list your general setup if possible. Thanks
ok, this should be fun. reply to this post with your info and we'll add it in.

don't apply for "not blown" status if a) you don't have a a turbo or supercharger or b) you have a turbo or supercharger but for less than 3 months/3000 miles.
it will be interesting to get more detailed info from everyone, since i was just going from a few posts/searches/recollection

I am firmly of the opinion a low shot of NOS is the most reliable form of power adder on the H22A. Getting more then one jet is just as bad as getting different wastegate springs though .
I suspect something in the H22A's design makes it susceptible to detonation.. NOS is cold enough so a small shot isn't an issue if the gas is there.
There are one or two blown NOS engines, but that wasn't on 50hp shots. I don't know anyone who's messed an engine on a 50hp shot (due to detonation or melted valves). It would be possible with operator error or component failure, I guess, but unlikely.

chalk me up on the blown side...
Code:
clendaniel 10psi, turbo, various ring lands...twice.
Also of interest would be the year of the motor that blew. I'm curious to see how many of the oopsies are on 00-01 ludes as opposed to a 97-99. (or h23)
I was running 7 daily, 10 a few times. My a/f seemed good on my dyno chart and I know my tuner retarded the timing for safety. I didnt notice any detonation and all my gauges seemed normal, then I started getting a lot of blowby and I had lost some compression in one of my cylinders. I dropped the car off at inline pro last weekend so we'll see what happens when they open up the motor. This was a 92 h23 with 68k miles, turboed for around 1-2k miles.

heh. see the post above. it's two lists. one is people who HAVE blown a motor, the other is people who HAVEN'T!

I would like to know if there are any people who haven't blown an H22 motor running with stock cyclinders (unsleeved).
I am a little surprised to see that silverludesi blew a motor with a Hondata. I would have figured that would make losing a piston a lot harder.
Maybe he can give us more info?
Props go to spinNlude for having the most spectacular meltdown

even though i am not FI i do have a mod that can blow your motor just as easily as going FI....but i have to say tht you are correct when you said that it is one of the most reliable form of power adders.... i have been running nitrous for about 2 years and not one problem from it yet.(well i had fuel solenoid that wouldnt close and was running very rich) but other than that nothing.
First i had it on my 4th gen H23 and i was running just about 3/4 a bottle a week on a 5o shot....thats a lot of spraying...but i check my compression all the time and not one drop in PSI,
Now i have it on my 5th gen, i have had it for about a week now, check pugs-clean,and my compression and not a drop in that either. But i expect the same thing from my last setup, everything is the same, from the kit(NX wet), to where the nozzle is mounted.
and it runs just as strong, getting just about what the jetting is to the wheels....closer,or more if its a wet...
But no matter what....we just dont get the glory of having a turbod/SC car....you get the looks and everything else that comes with it

Hey, how long did Smitdog have his JRSC on before his car was hit and totalled? I know he never had a chance to get it on the dyno or a wideband O2, but urban lore tells that his car ran beautifully, god bless its soul.
heh.. You can bump my setup to 9psi. I've been running that way for a couple of months now, but I just chose not to advertise it.
Also add "J&S Safeguard" to my setup
On a side note: I *will* be building an engine for next year. The amount of power this engine is making now makes me a little nervous.
On the subject of tuning:
How can someone be sure that their car, tuned on a DynoJet dyno, is not detonating? I know that on a Mustang dyno, you can play with the chart views to actually "see" detonation. Even if the A/F ratio is correct, there is still room for error in the ignition timing... so how do tuners make it work on a DynoJet?

I've never worked with a Mustang Dyno, but I'll assume they do something analogous to DynoJet's "smoothing" function to create a more sensitive graph.
First motor that blew is in the "blown list" JR ems/fmu motor was the original 98 with 47xxxmiles Nitrous ran by previous owner started a melt down of one of the Pistons...there was a hole the size of a grape right where the ring lands are, when we added the boost it took out all the rings
New motor (2001 w/8k) have had it for exactly 3 months about 4,000 miles not blown still using the JR ems/fmu so you can add me to both lists ha ha ha
Smitdog had his car for about a month before it was murdered!
