1532.0. "VTEC CRX Rev limiter" by SEDSWS::PHIPPEN (what happens if I press thi..) Wed Aug 28 1991 18:03

    
    Does anybody out there know anything about the Rev limiter on the CRX
    VTEC, Basically what I want to know is can it be upped or removed,
    the engine (due to variable timing) is capable of reving to 9500 revs,
    without damaging the engine, which the CRX challange and the 24
    indurance cars do. These cars are standard apart from uprated suspension
    and brakes and a blue-printed engine.
    
    Also, How do you get rid of a stinky-horrible catyliser with out voiding
    your warranty.
    
    Thank in advance

1532.1	there's a reason for it	OASS::BURDEN_D	He's no fun, he fell right over	`Wed Aug 28 1991 22:19`	8
	The reason they can rev to 9500 rpm without damage is because they have a blueprinted engine. This sets the tolerances a little looser and balances all the moving parts. This makes it possible to rev higher with less friction (less heat), and fewer vibrations. Granted, your stock engine will probably survive over the indicated redline, but don't plan on making it reach 9500rpm at every shift, for very long..... Dave
1532.2	Frying tonight	DOOZER::JENKINS	seriously 'ken shabby	`Thu Aug 29 1991 03:41`	7
	I would imagine that the rev limiter cut-out is controlled by the engine management system. If so a new chip could change a few characteristics. Why not try a 'chip shop' or a tuning specialist who prepares CRXs for racing? Richard.
1532.3	Lock it up	WARHED::GILLILAND		`Thu Aug 29 1991 08:49`	15
	> engine will probably survive over the indicated redline, but don't plan > on making it reach 9500rpm at every shift, for very long..... In fact, don't plan on keeping it for too long: Thursday 8th August - fellow engineer receives new CRX VTEC. Monday 12th August - car nicked from outside his house Wednesday 15th August - car found, wrecked. The recovery wagon turns up to tow it away, and the owner offers him the keys to unlock the steering. "Don't need them for this mate" says the wagon driver, and proceeds to unlock the ignition by shoving a screwdriver in the keyhole! Phil Gill.
1532.4	Try these people...	ARRODS::WILLIAMSON		`Thu Aug 29 1991 16:39`	10
	For CRX stuff, try Nick Tye Autos. I hear they're pretty good. They advertise in Performance Car, if you want the number. Also, I think you'll find that Brodie Brittan Racing might be able to help. I had one of their StarChips put into my BMW M3 a couple of weeks ago, and it upped the rev cutout from 7,200 to 7,800, as well as made her pull even better after 4,000 - all with no loss of tractability low-down. All in all, I'm pretty impressed. Dave.
1532.5	?	DCOPST::BRIANH::NAYLOR	Tigers fly, Spiders roar!	`Fri Aug 30 1991 15:37`	3
	If removing the catalytic convertor would void the warranty, then what is the effect of removing/altering the rev limiter? Surely, the same? If you're not bothered about one, then why should the other be an issue to you?
1532.6	Friendly warning	CHEFS::PALMER		`Mon Sep 02 1991 15:52`	9
	Jason, A friendly word of warning.....your's is a company car which you shouldn't tamper/alter without Car Fleet's and the Leasing Co's permission. Also, Insurance won't be too happy ! .... guess where I work ?
