then that is irrelevant to this. ofcourse u can rev a built motor past oem limits. you could have a motor built to rev to 10+.

 

im also reving to 8500 with dual valve springs, super tech valves, guides and retainers

 

You will need cams if you want to make power in that range like boostedf22c mentioned. But do us a favor and dyno plot the stock f22 cams and see exactly when the power curve drops off. Swapping out the f22 cams for some f20 should help since they have a higher rpm efficiency range, though you will likely sacrifice some of your lower/mid power band. Thats typical though if you are making power in a higher in the rpm range, you cant have it all. At the least, being able to maintain your power output from stock redline to 10.5k rpm would still be somewhat beneficial.

 

Talking from experience, you can rev a stock f22 block to 9k without issue, Ive done it numerous times, we just don't know the longevity of doing so, so I try and pay attention to my shift beeper and not go beyond 8500.

 

Sounds like the best way to do it

 

Haha... right, because I said that your internals will last longer with boost... Its been discussed plenty of times over, you can safely rev higher with boost in regards to your now forcing air down not sucking it in which creates more stress at higher RPM on your wrist pins. You can argue about sideload and excess wear all you want thats not what im talking about.

 

I'm not sure why you think forcing air in will create less stress on the wrist pins. The highest stress on the wrist pins comes during the combustion process (obviously) not the intake stroke (which I think your implying). Since you are likely to double your torque with FI you will come close to doubling the stress on the wrist pins. That's obviously not exactly true but its close enough... certainly a lot better than saying you have lowered the stress.

Not that it's relevant the wrist pin isn't even close to the weak link.

The pistons don't get forced down harder with the added "forced air" resulting in more power and turn stress. The FI allows more air to be trapped in the combustion chamber on the intake stroke so that more fuel can be added in relation to that added air, which is what creates the added power and stress, its artificially adding more air/fuel mix into the combustion chamber on the intake stroke. More air/ more fuel= more power.

N/A is relying on the vacuum of the piston to draw in the proportional amount of air into the combustion chamber which that size/displacement motor can make/consume. This is why FI is recognized as a engine displacement modification because it allows an otherwise small displacement motor to consume an artificially higher displacement amount of air for its size.

So to re iterate, there is no Forced air pushing down on the piston in any FI set up. Its not whats happening inside the engine. It is simply allowing more air to be consumed into the combustion chamber during the intake stroke so more combustion/explosion can be produced, which is what forces the piston down harder to make more power,
( the combustion!)
