Im wanting to know which amont of psi to tell the Tuner to set me for so I can get the MOSSSTTT reliability and LEEASSTT chance of blowing up. 3-4 psi comes to my mind. Thoughts?

why not just ask your tuner? but the standard for stockblock hondas is anywhere between 5-8 psi

How do you have 2.4 liters?

I wouldn't go over 5-6 psi on a good tune if you want to be totally safe.

 

oops. thats a typo. 2.2l. completely stock.

So, you guys think 5psi is safe? I just spent 4.5k on all this ****, and I really dont wanna spend 3k on a new motor if i blow this one up. lol. I take that back, i dont HAVE 3k to spend.

 

i've heard the magic number is up to 8psi stock block, but ppl have pushed things even further on stock h22's, in my own opinion i think if you can keep charge temps down with good intercooling and choosing the correct turbo for the power you want (not psi) then with a smart tuner you can successfully boost a stock H22 and keep it reliable, just dont start thinking your going to start pushing 500whp with a stock block. oh yeah, and because i got told this all the time.....SEARCH!!!

 

its not about psi. its about the amount of power you output at X amount of boost. Your turbo setup determines your amount of power at X amount of boost. Some make 400whp at 10psi, others make 300whp at 10psi. The only difference is the setup.

This is why you get on a dyno and let the tuner do his thing (depending on their credibility that is). I've never heard of the turbo you are going to run before but theoretically it could take more than 8psi to reach that threshold of conservation.

 

so, with that setup, what do ya'll think I should be hitting HP wise?

The turbo is SS autochrome

i'm not a dyno. Go to the dyno and find out.

btw, that turbo has a horrible reputation of cracking and leaking all the expensive boost you paid for......should have done your homework.

 

cheap boost ftw

my friend had an ss autocrap manifold and it cracked and the braces fell out at like 80mph, sounded like hell....then leaked boost all over the place, and then repeat that 2x.....

edit: was that complete list of everything in your car including the stale fries under the seat for fun or what?? with 5% tint you will make 56 more hp than if you had 10% dood....trust me, i have a last name but i can't pronounce it....they just call me carlos

Pretty sure they called him Hector...But Carlos sounds like it would word too!

"I've seen how you drive Brain, You've got a heavy foot...."

 

All making fun of me aside, yes, that was a complete list. Its found on my cardomain. I just copied it and pasted.

Yes, I know the turbo isint the best. I found this out shortly after I bought it. Hopefully mine will be okay since its such a small amount of boost. Its the only thing thats really "cheap" on my car. Hell, my avc-r cost more then the turbo. $500 *-*

Thank you Blake ....I can't stress this enough man.

 

Yea, this tuner im talking about is VERY respected here in the KC area. He's owned his shop for a long time, and tuned many cars around here that are VERY quick.

I think I'll shoot for 5psi

 

who is he?

i've learned not to take peoples word for it.

 

You have an AVC-R and are now going to get it "professionally dynoed and tuned"... ? Why... sell that b*tch and get a Garrett hybrid.

I'm assuming you already have a chipped ECU and Crome ready to go.

 

avcr is a boost controller.......

 

I recommend an equal amount of boost...So if you want to add 50whp, Give it 50psi...Should be great!

 

Blingy boost controllers and ebay turbos?

Oh well...

The problems with FI and reliablity are probably exagerrated if the whole thing is tuned to a tee...but turboing while not having the money for a new engine in the event of something stupid happening is probably not the best idea.
