A friend of mine will be running a chipped P28 on his B16a with stock internals. Is a 9000 RPM revlimiter to much ? What would you recommend? Thanks in advance for your input.

 

I wouldnt go higher than 8500 with stock valve train.

 

i had the same set up with my b16 i had no rev limiter but i never went over 9k, you should be fine.

 

rev any higher than 8300 on that b16 you can count on your valves floating...

seriously..
8300 max.

yea, 9000 is over the top. Don't do it.

 

he won't be making any additional power at those higher rpms... so what's the point?

does he want to watch the tachometer stick go all the way down that bad..

 

stock valvetrain.. you start to lose power at about 7400.. no need to go that high..

 

yes too much on stock

 

I have a JDM B16 and when I had my Vafc installed I decided to have it tuned and from looking at the dyno sheet I recieved peak power was around 7800 to 7900 rpm. There is really no need to go much further past that. I tend to shift around 8000 to 8200 rpm. Shifting to 9 grand with stock valvetrain is asking for trouble. This debate could be concluded by going to a 1/4 mile track and try shifting at 9 grand all the way through and then shift at the stock redline 8200 or 8300 rpm and see which is faster. I guarentee that shifting at 8300 rpm through the gears will give you much better times.

 

There's no point in revving any higher than the stock fuel cut with stock cams.

B16A stock valvetrain should be good for 8400 RPM. Honda set the fuel cut at 8400 RPM on the 2nd-gen JDM B16A for a reason - the valvetrain can't reliably handle higher RPMs.

If you want to rev higher, you better get yourself some upgraded valve springs, or else you'll risk floating valves. At the very least, you will bend valves; worst case scenario, all of the internals will self-destruct and blow holes through the block.

This is correct for a 2nd gen JDM B16A, which has a power peak around 7800 RPM, redline at 8200, and fuel cut at 8400. For a 1st gen JDM B16A or a USDM B16A3/B16A2, the power peak is around 7600 RPM, redline at 8000, and fuel cut at 8200.
