when does a f22 stop making power

[pr3pg4lyfe]

I've looked and looked and searched. all I found was around 5800 rpm. can someone help me out with a more exact number. planing on getting a shift light for days I'd like to go to the track and see what kind of numbers I can pull. also I was thinking about getting a chipped ecu and add rev limiter and 2 step. I no you can't do much with a f22 and a chipped ecu but if anyone else has any suggestions feel free. by the way also will be swapping a motor somewhere down the road. so its another excuse to get a chipped ecu.

I recommend you read through some N/A build threads in the N/A performance section as that will answer most of your questions.

As for a stock F22, power drops off very quick after 6k. 3k-5k is the torque "sweet spot" but during a drag with the f22 tranny you'll want to rev it to 6.5k in 1st to keep 2nd from dropping you too low. Shift out of 2nd at 6,200. You won't need 4th or 5th in the quarter with a stock F22.

5500rpm is where i shifted mine when i had the stock camshaft.

I believe the maximum power is about 5.600 rpm e torque about 5,400 rpm, so shift high, over 6,000 rpm as said.

thanks for the input guys i havent checked it in a while ill refresh my memory now.

Your best bet would be to find a place to do a dyno pull. Many large car events will have mobile dynos that you can strap your car on for a fee. Then you'll be able to see where your specific engine drops off.

As for a chipped ECU... You may lose power if it's not tuned properly for your specific engine. If the engine is near-stock, you don't need to adjust the rev limiter... there's no power to be had from a stock engine beyond the stock limiter.
As for a 2-step, get the actual "2-step" unit from MSD for a spark cut. It's a bit safer than an ECU-programmed fuel-cut (though a simultaneous spar/fuel cut is idea...)

sorry im not exactly sure what its called. when i ment rev limiter i mean lets say im going down the track im in second i dont want the motor to go past lets say 6500 rpm. and as soon as it hits 6500rpm it stops sorta like a 2 step.

also i was actually thing about getting a ma6. but i couldnt find how to wire it on our cbs.

What you are talking about is just a rev limiter. A fuel cut. Your ECU already has one in place (I know my Fit does... I've hit it... ) You'll be out of your engine's powerband by the time you hit it, unless you have at least an upgraded camshaft.
If you're going down the track and you program a fuel cut... and you hit that fuel cut at full throttle... You're going to be running insanely lean for that instant. You can do serious damage if you do that. If you don't want to go over a certain RPM, just don't go over. Shift to a higher gear, or back off the throttle. The ECU isn't driving the car... you are.

A 2-step is a rev limiter used for launching... keeping the RPM at the optimal level for a launch without too much wheelspin. Similar concept, different application.

ma6?

mine with basic bolt ons made 128whp and 132 tq and it dropped off around 5800

sorry I was half asleep posting lastnight. I was planing on getting a msd 6al is what I ment. I thought wiring it would've been to difficult so I never bought one.

[deevergote]

Wiring wouldn't be very difficult, but there is really no benefit to an ignition system upgrade. You won't see any gains from it.


So many people buy unnecessary parts and do unnecessary mods without doing the proper research... it's unfortunate, in a community such as this one that has so many members with very limited funds to work with.

[pr3pg4lyfe]

yea i know it sucks not having alot of money to get parts we want/need.
about the 6al i was only going to get it for the 2 step application they have.
