Everyone already knows the stock sleeves are thin, and the piston ringlands are weak. It is also common knowledge to "reliably" boost an H22 you need to build the motor. (Sleeves, pistons, rods etc ) Which we are going to do

But out of curiosity, is there anyone on here or anywhere who has boosted over 10 psi on a stock H22 and done it succesfully?

(Stock meaning never been apart: stock rods, stock pistons, stock compression, stock bearings, stock head gasket, stock studs, stock head etc.)

I don't want to hear the stories of people who have blown up their H22 with only 7 psi, those people don't know what they're doing.

I want to hear from people who have been successful at boosting their H22 over 10 psi


I actually rode in my boys 97 prelude (a couple of years ago) that had a JRSC. We put an upgraded pulley on his charger that caused the boost to spike to 11psi.

He drove it a couple of times with the pulley, and we could hear it starting to detonate right before the belt started slipping.

Since the belt would slip with the upgraded pulley he decided to put the original pulley back on.

Anyways, the funny thing is his Lude is still boosting on the road today and has never blown up.

 

Our secret is we boost between 9- 10 psi at the track

& 7-8 psi for daily driving, for almost over a year now

 

Hey!
I want you guys to tune my lude. maybe we can run it at 10 psi for awhile. just kidding. i am scared to run my lude over 8 psi.

 

anyone????

 

There is no doubt that it can be done.

The question should be for how long.

 

my friends h22 lasted 3 shorts trip around his block @ 10psi

 

exactly... that's why I asked has anyone done it successfully

 

Ask Mase...

 

I ran 15psi for a while and then my motor dropped a valve ( DPR stage 5 Head). Other wise stock short block and head gasket/bolts h22a1 motor

 

i know someone that did/does but u said only personal experience...

 

H22 with a cometic head gasket running 11 psi lasted for a long time. On slicks ran 11s

 

same setup as my friend...h22 with inline pro head gasket.... running 13psi... lasted for almost one year now... hondata...

 

11psi on the dyno and a couple weeks later a couple pistons ringlands gave up.
