rev limit????

[jezB18c3]

hey all. just wondering, i've got a B18c3 in my ef and ive been told that the rev limit in these are 8900rpm (well max power is achieved at 8900). does anybody know where rev limit is suppose to be as i had a miss shift at 8900 the other day and my tacho showed all the way to 10000 and the needle was bouncing, i have since taken it to 10k and it makes good power even at high revs. any suggestions?

what mods u done to ur motor to make power that high???

[ProECU]

i never knew the EF tachos went to 10k

[jezB18c3]

yeah they dont. but my autometer does. i figured that i would be needing one once i had the b18.

[ProECU]

what computer (ECU) are you running ?

[ewendc2r]

*cough* bullshit.

9500rpm sustained (not mis-shift) is nearly catastrophic failure for a Type R motor. More so, there is no need to take it that high (although, in a NA engine, the higher the revs, the better, at the cost of relaibility)

They develop max horsepower at like 8200rpm stock I think.

[jezB18c3]

what do you mean by *cough* bullshit? im not lying to anyone mate if thats what you are saying. the motor that i have has come from japan and im just trying to find out more about it. thanks mate.

[ProECU]

no offence, I rekon its bullshit too, what ECU are you running?
It could be that your autometer is incorrectly calibrated.

[jezB18c3]

what computer (ECU) are you running ?

the ecu that came with the motor is stock but has a spoon sticker stuck to the bottom of it, hence me not knowing what the rev limit is as it doesnt seem to have one.

[jezB18c3]

and the autometer stays with the stock tacho all the way to 8k which is where the stock tacho stops.

[ProECU]

ah OK
those spoon programs tend to set the redline really high, possibly up to 70,000rpm as a way to override the redline.

Personally i'd take it to a dyno to get a readout of a/f and peak torque.
From there you should be making decisions around redline.

Do you know of the motor has been built at all?

Any further info would go good here too

might have an unknown sleeper.

A mate of mine got a ca18 imported to put into his car. Turns out that it has mines internals, ecu and eerythin. Can rev it out to 11,000 RPM and has done so on a few occasions while drifting.
