what is rev limiter on a d15b and what will vtec engage at?

 

depends on the ECU your using

 

sorry bout that p28

 

while we are on the subject, what is the safetest to rev a stock d16a6, with stock ecu ect.....

 

I think the stock D16a6 rev limiter is set at somewhere around 6800 if I'm not mistaken......good luck

I would imagine the p28 would be similar.

 

thanks

 

how high could i rev my d16a6 safely? if i were to remove the rev limiter somehow?

"rev safely" and "remove rev limiter" don't belong together. =P

Depends on your modifications. Remember, D-series rods are like toothpicks. The rod bolts are also extremely weak. Spun bearings become a factor with that.

I'd say keep the stock rev limiter on a stock motor unless you upgrade to ARP rods bolts and H-Beam rods (or similar).

The rod to stroke ratio and reciprocating mass issues must be addressed. Your redline is there for a reason.

^^ true to a point. The stock A6 is not worth anything above 7200 where the fuel cut off is. It will not make any usable power. revving that high is pointless on a stock motor, unless you are just trying to destroy it.
Even after the bottom end upgrades you still have the rod stroke ratio to worry about, It will put EXTREME pressure on the cylinder walls above the stock redline.
I am pursuing an engine build with modified stroke and piston height, I hope what I have planned will work out.
I'm still not going to rev past 7500, but I hope to make significant power gains in the stock rev range....
