alright I got a F22B1...and i read the compression is like 8.8 to 1 which should be low enough to have a turbo setup but only run maybe a max of 10 psi...now would the internals handle the 10psi or would be a definate internal change to get a turbo on the F22B1?

 

I've always heard to keep it between 6-8 psi to prevent possible damage to the stock motor.

 

alright but its not like i would have to change the internals...and with that motor and a turbo on it ...would be pushing like 250 wheel horses or what ya think there

 

i wouldnt say 250. my old subie would run around 16psi and thats with tbe and a few ecu mods. making it around 265 atc.

im saying more like 175whp maybe a few more. you have to realize that car stock is what like 130hp atc and maybe 100 whp so adding a turbo at 6-8psi isnt gonna make you jump 150hp just like that man.


just my 2 cents

 

6-8 psi your looking at like 190ish. if your lucky.

 

lets see if I can remember the formula for this one.... I believe atmospheric pressure is rated at (using what I recall it to be rated at for the sake of argument however I think it's closer to 14 than 17) 17... so if pressure of 17 yeilds 145 HP then 17/145 = 8psi + 17/X or 17/145=25/x, that being said you'd get to ROUGHLY 213 HP at 8 psi...

 

huh?? it all depends on the motor also. u cant say u got a b16 sohc and u put a turbo kit on it run 10psi. then u take a b16 dohc vtec and run the same setup. i guarantee its not gonna be the same horsepower. i guess all the guy can do is try it. you can put a nice kit on it and get 200hp then acutally tune it correct and get say 25 more hp out of it. of course those numbers are just made up but you get the idea. it just depends on how much money and the correct tunable parts you want to install. 6-8psi means basically nothing at this point. and is that 6-8psi with what turbo? a tdo4 housing turbo or a tdo5 running x ammount of psi. so many differnt ways will answer the mans question

 

My numbers are based on the current horespower rated with the air pressure that the vehicle is currently running as compared to that SAME vehicle SAME motor with increased boost. Yes boost is different for every engine that's why I calculated it based on his particular motor...

 

i understand but that is also stock brand new specs. what mods has he done it might have 200k on it and dropped 50psi in compression. so on so forth you get my picture

he said he read the compression is 8.8 to 1 which it may be sounds weird tho. you would think it would just be like 9 to 1 or 8 to 1. anyhow.

i get what your saying not trying to contradict your theory or anything just implying the facts we have here.

 

gotcha... that makes sense... I guess a better way to answer would have been to say that depending on engine life etc. you can estimate 25-75 hp at 8 psi (unless the rings are shot)
