your dad is right.

most factory turbo engines are <= ~8.7:1 compression

if you go easy on it it will last. if you rape it it'll last a lil while

Running and f22a1 right now boosted at 10psi...you father has no idea what he's talking about. And the f22 has 8.8:1 compression not 9.5:1!!! Even so when i do get forged internals i'm not gonna lower the compression i'm gonna raise it to atleast 9.1:1

www.cb7tuner.com you have a lot of searching and reading to do man...so does your dad.

to many 'ers' and 'yurs' and 'da's' and drama with slapping an intercooler in the face.

especially a large one to keep the boost down. thats what wastegates do, that is der job ya herrre me. holla

just boost the thing and you'll be in ricer heaven.

(i guess i don't sound as cool when i put in the der's and yurs and ---- like that.)

I can't beleive anyone would raise their compression when building a turbo motor for a street car....

whats with all these new guys and them not boosting their car because their mommy or daddy wont let them

I get alot of that...great things have been accomplished by ppl that think outside the norm tho.

Its all in the ignition tuning and not exceeding the octane's limitations

Besides its not like i'm raising it into the 11's :P

compression is definitely 8.8:1.

boost the ******. there's a few of us around here who have.

A lot of the used turbos with internal wastegates are set around 7-8 psi - perfect if you're worried about running high boost. If the c:r was lower, you'd have to worry about the sleeves giving way with "high boost". An extra 80whp @8psi for $1.5k is nice. In the end, its the tuning that dictates what's safe on a non-low c:r engine.

this story reminds me of a guy talked to when i was doing an install on my buddy's integra. almost exact words....."you cant turbo that engine because it's compression is too high; it needs to be 8.5:1 or lower". i was cool about it at first and basically said there are 1000's of stock honda motors on boost running around, and it has more to do with tunning than compression numbers. then for whatever reason, this guy when into "i'm a know-it-all dick" mode talking about he went to school for this stuff, blah blah blah, and how he's gonna laugh when it blows up. he had gone to UTI or something comparable. i blem him off after that..........

anway, long story short, the car is still running just fine 6mon later.

good luck with your project

so.. teach your dad a lesson.. sell coke and turbo it yourself.. once he finds out his son is coke dealer he really will wish he had "got your back".
