I was having an disscussion with a friend about compression. He said it was unsafe to turn up the boost on his H22a Turbo.

He has a 94-95 JDM H22a with an AEM plug and play,T3/T4 and 550cc's. I told him 400+ isn't as crazy as he thinks.

I was under the assumption if the engine is tuned correctly compression isn't a huge issue?

Can anybody give me some help either way? We'd like to end this disscussion tonight.

P.S. I spaced the post out for everybody's reading pleasure.

 

The lower your compression with boost the better. With high compression on a boosted motor you have a lot better chances of detonationg your motor while you are tuning it. With lower compression, you lessen these chances. Also with lower compression you can get away safely with more boost. 400+? Are you talking about 400whp? Have you ever been in a car with 400whp? I speak from experience, when you ride in a car with that much power every other car feels like a slug but sooner or later you get used to 400whp and you want more. On a stock h22a i wouldnt push anymore then 8psi due to the weak ringlands. I hope this helps to end your discussion.

 

Yeah 400+whp is the goal.
What are ringlands again?

 

hello just to let you know 10secondr33 he has a 990 whp TT Supra and a Skyline R33 1000+ hp im sure every car seem like a slug to him.. haha

 

That is so true

 

13:5:1 Compression works good for turbo !

 

well in that case 400whp isnt **** lets see some pics of them if you dont mind

Hey the Skyline is under Realblazeracer so do a search. The Supra is pretty much a sleeper and not much to look at! But the Hp EGsick posted is the real deal. We don't front on HP!!!

dont go to low with the compression. 9:0:1 somewhere in there will be fine..
ringlands are what the ring sits in. they keep the ring from fallin out u know the grooves...

 

you da man BoostedH23a1!

is your compression down? if so what are you using to lower it down? example je pistons , crower rods?

thanks

 

holy ****..
how can you afford to have an r33 skyline in the us..
tell me your secret

 

haha if we tell you we must kill you! haha
