9200 Rpm rev limit... too high?

Postby Lunchie » Tue Oct 04, 2005 9:14 am

hey guys a mate of mine just got his 1.8 vtec integra engine tuned with a link and the guy set it to 9200 rev limit. The engine is NOT a type r model and has standard everything bar intake and zaust. Does this sound a little high to you guys?...

Dont want my mate blowing up his new toy as he's one of the only honda drivers i know who's actualy a really nice guy

Cheers

as long as he doesnt hit it, yea it will be fine.

Im interested to see how quick she is now that the link is actually been tuned rather than.......

this car has a link computer, its set on factory settings so doesnt do much more than the old ECU did, lol

I'm unfamilar with those engines. However that piston speed is really getting up there. Remember that the Link cuts fuel 200 rpm before the limit, and if your anything other than stupid you button off or change on the first falter at 9k.

If your friend is after engine longivity that RPM limit is certainly not the way to go about it.

Nah, just let him rev it out. Its just a Honda anyhow. And when it blows, pull the pistons out and use them as ashtrays. :P

It will probably take it for a suprisingly long time, but unless its been modded a bit, should just leave it at the factory cut..

i wouldnt take it over 8500 often, unless he has spare dolleros for a rebuild

Sounds a bit high, even the Gizzmo chips (which IMO have too high a rev limit for most applications) set it at 8500. Just borrow a hand controller and bring it down, its not hard to do.

Where does the power start to fall?

standard everything? no idea how strong those are, but itll be falling waaaay off the power long before then.
id say factory rev limit would be the best to use.
do a dyno run, see what happens to the torque curve, then use that as a guide. but id be pretty nervous taking my stock engine to 9k 8O

Speaking of high rev limits (sorry to hijack the thread), whats the highest safe rpm point for a blacktop?

I haven't seen a factory taco from a blacktop recently, so don't know off the top of my head where the redline is ... 7500rpm isn't it? 8000rpm?

I've had 2 VTEC's that I was in charge of driving nearly daily for a year or so each, and they pretty much lived on the 8200rpm (?) rev limiter, one was a B18, other B16, and they $&#$% loved it... :lol: :lol: :lol: :lol:

I've got 9k cut on my silver top, had it for 2 years hit a few times on meremere, it is not a soft cut BTW, feels like fuel cut. It is lazy after ~7000 anyway. If I do shifts just before 9k I will have slower times, then if I do at 7600-7800... + I don't know about honda but with toyota sychros don't like to engage properly at very high rpms anyways...
