Boost on Stock F22A6

[boostdelinquent]

Can someone tell me what the commonly accepted max HP for a F22 block is assuming that the tune is good? I looked around and didn't find a whole lot. I was also wondering if H22 ARP headstuds will work since I couldn't find any listed for the F22 although my wholesalers website is weird like that at times.

around 230-250 is reliable on a stock block, more with a built block.
but again it all depends on your engines health.
a leakdown check would be the best thing before doing anything.

Are you planning on building,semi sounds like it since your asking for ARP head studs.
As far as this situation is concerned, go with H23 head studs, H22 will NOT work.

could be like straightedge and do 20psi but he only ran it on the track.

[drummersteve7]

I ran 16 psi on my car for 3 days.
of course that was 3 days, of getting on it, cause I was trying to blow the engine!!! I win!

The plan is to boost it on stock internals w/ ARP's to avoid head lift at higher levels of boost. I know w/ D-Series you can generally go to about 190whp or 10-12lbs on the stock headstuds before lift so I figure it'll be cheap insurance on the F22. Other than the ARP's I'll probably pick up a second cam from the pick and pull and send it off to Delta Cam for a regrind and also add in a set of Supertech springs since I can get them for cheap. I'll be calling them later to see what they suggest. I'll prob also throw in an AEM cam gear for good meausre.

From there I'll have to figure the rest of the build out. To start off I want it to be as much of a reliable budget build as I can achieve but would like to DD w/ 275 to 300 on stock internals so that might throw reliable out the window, unless I tune for 300 and then turn the boost back down to make about 250 w/ 300 being reserved for track/race days. Even if I do blow the engine that'd be OK though. The local pick and pull is loaded w/ F22's for dirt cheap so it wouldn't really break my heart to have to buy another short block not to mention it'd give me an excuse to build the bottom end once that happened.

irony in your sig. lol. NA is best but you're boosting

[boostdelinquent]

Yeah, I've had that in my sig for a while. I do prefer N/A on most builds but the CB7 isn't exactly a light chassis so it's a better bang for the buck to boost it.

I'd say if you want reliability, boost at 7-10 psi. Your pistons are the weakest link and the ring lands will break off probably before you get issues with cylinder head torque issues.

With stock internals, your always running the risk of blowing up your engine, especially in the 250-300 hp range. I'd just boost it safely and get a lower 200-230 hp on stock internals, or build it up a little bit and reach your 250-300 goal.

[boostdelinquent]

Well, the CB7 i was going to trade my hatch for fell through so looks like I won't be doing this afterall. Oh well, still covered some good info for future reference.

Plan on getting a cam from bisi for 300hp with that boost like me...I would run 8-10psi with the cam and make 250-300.... Then to rely on boost making the power...I talked to bisi and its a very good combo for a D.D,.....AND ITS QUICK...Think about it....

ive heard you can mess alot of s**t up with a f22 boosted just go with a h22 it would be better plus na cars are better

that is a rather highly subjective statement to make

[straightedge]

could be like straightedge and do 20psi but he only ran it on the track.

this is a false statement, fwiw.

[dbsharp]

how much abuse did your motor take?

Why would you say that?I drive mine everyday and its fine.Its really good a matter ah fact..I say true if you just throw a turbo on and take it out and run it to the ground,Without doing the right stuff)...But that is any car.......F22's are real low compression 8:1 very boost friendly...But the ring lands are the weakeast link...But the bottom end is strong..Im telling you....I know a guy that ran his at 21psi but just a few times.And ran it for 5years on 12psi after that....And there is alot of other guys here that would tell you the same.....Either stock or built....F22's are nice in my book.H22 is also good for a N/A and for turbo but i don't think i would just throw a turbo on one of those..........Like we can if the motor is healthy.......But Im sure someone will say otherwise
