Rev limit difference between revisions? (3S-GE)

[LukeSi]

Thought I would pop this up as it has been puzzling me. My Rev 3 (albiet with a Celica block) hits the rev limiter at 7250RPM. Someone else I know has got a Rev 4 which revs to 7500RPM.

Both of these are UK cars. I've "offered" to test his ECU but he wasn't up for it Any ideas?

It's 7250. Their rev counter could be inaccurate. Having used a toms ecu on that rev3 on engine I can tell you there's no more power after that anyway. It's only handy to stop hitting the limiter by accident.

The UK Rev 3 3S-GE ECU has the rev limit set at 7400rpm. The stock rev counter does tend to under read.

On a side note we had a drag race, my rev 3 T-Bar against his rev 4 T-Bar,

I was finished about half a car in front of him, that wasn't from my launch, I actually started pulling ahead getting higher up the revs.

(We didn't have much space it was in the paddock at Curborough sprint circuit)

Are they both UK cars?

[LukeSi]

Yup both UK cars, although mine has got an induction kit and a decat.

A UK rev3 has marginally more power than a UK rev4 due to the addition of EGR. It's only 174 vs 168 or something though.
