Wondering if one of the pros here can explain how you can blow a maf by bouncing off the rev limiter as stated on page 3 post 44 by 02996ttx50.

I could see how flow could exceed its calibration limits, but if you are rev limited to a max rpm how would that damage a metering part?

I have the tendency to bounce off the limiter in 2nd (as i have in many cars Ive owned) however, Ive never heard of this before. Any info would be very much appreciated. Thanks

I would love some input on this as well!!!

 

the way it's been explained to me is that the spikes can cause too much voltage(??)( eg 1.3 rev limiter bounce for example..) and can kill the maf. not sure if having a raised rev limiter allows for this to occur ( which mine's raised to 7200 iirc ), but it's not an issue with a stock tune ( or so i'm told ) i would also like to separate myth from reality on this issue. anyone has ever seen one, it's not the *sturdiest* looking diode ever made.

 

I would be more concerned with the bouncing off the limiter then a $200 MAF part... just a my opinion...

it happens. just thankfully, not every day. advice or info re the maf less tune(s)? or not lol. thx
( 2nd is the only gear i've "bounced: in too. not for nothin' ).. i'm thinking raised limter is a component of the potential for failure.
but thats a WAG.

 

And...it's faster than 24/20's . Until you prove me wrong.

 

I don't believe it was faster than the 24/18's. I just don't spend my time running 1000's of 60-130 to eek out a great time.

The only time I tried with 24/18's was at the track when it was rather warm & the 7sec 60-130 time was on pump setting.

Heck if they were faster than the 24/20's then they must be faster than your car now. I thought your foot slipped off the gas pedal when both Dennis (n/a Z06)& I left you pretty bad coming back from the track a couple of months ago.Just sayin.

 

Are people not liking the Alpha28's no more?

 

I don't recall this situation. Is there a video?

 

I know... Check my earlier post. Alpha 28/30s rock!

 

i think the main issue is the high cost compared to a k24/20 build. approx 3000$ more? in that price range you may as well go 3071 or bigger

 

That all depends how and when you want the power to come in at..

 

agreed. my point was anything above the 1500 to 2000$ billet build jumpos to 5000$ and up for 28's or bigger. thats imo the main reason 28 arent as popular as the bigger turbos. if your going to pay that much may as well go bigger

 

I'm sure with a built motor, at least rods, even better with rods and pistons to jump to 3.8, and with the Alpha 28s, a car would be faster around most of the tracks than a car with the same motor but with much bigger turbo cars.

Right?

 

Then you need more $$$ for clutches,tires,chassis work to make it hook and worry about breaking things with the big turbos.
Some like the instant hit of the A28s for roll ons and dont even take it to the rev limiter?
I like top end power,small block RPMing over big block low end torque..
I think its easier to launch without that sudden low end hit right away with the bigger turbos, my kind of driving..
To each his own..
