extreme33 Posted October 26, 2011 Share Posted October 26, 2011 hey all. New to the forums here but been researching skylines and know a fair bit about them. Just having a few thoughts about the engines themselves, I know everyone would recommend against it but i have seen my friends sometimes hitting the rev limiter in second gear before changing it into third. Have spoken to them about it but havent come up with any conclusions as to how bad it could be for the car doing this. Anyone willing to shed some light on this issue? Wanting to know how much damage it could do to their cars. I know it cant be good for their cars but not sure exactly how much damage it could be doing! One of theirs is a 33 with fmic, bigger injectors, pod filter w/cold air intake and an ebc. The other just has a fmic with a pod with intake? Cheers in advance Link to comment https://www.sau.com.au/forums/topic/381298-rb25-hitting-rev-limiter-street-use/ Share on other sites More sharing options...
zebra Posted October 26, 2011 Share Posted October 26, 2011 1 major thing.....Broken oil pump Also...dont be a dick on the street Link to comment https://www.sau.com.au/forums/topic/381298-rb25-hitting-rev-limiter-street-use/#findComment-6080955 Share on other sites More sharing options...
extreme33 Posted October 26, 2011 Author Share Posted October 26, 2011 one thing i thought would happen. Oil pump then leading to vast engine damage? I know they have their limiters set to a certain amount. But Im still confused as to how they can think it ill be fine. Their answers to me were that the cars can take it if they have a good cooling system and good oil pressure etc. Sorta glad my 33's still in the shop off the road. It hardly gets much use. Ive got the track car to have my fun and let off some steam but they dont hence why they take their car to secluded places etc. Link to comment https://www.sau.com.au/forums/topic/381298-rb25-hitting-rev-limiter-street-use/#findComment-6080966 Share on other sites More sharing options...
boostn0199 Posted October 26, 2011 Share Posted October 26, 2011 If your hitting it every now and then and not sitting on it for long its probably not going to break shit but constantly hitting it and just riding on it yeah one day youll probably start hearing your bearings lol.

Moodles2 Posted October 27, 2011 Share Posted October 27, 2011 It's not the problem of high revs, it's the problem of the hard fuel cut causing stress on the oil pump gears when they smash together. As long as you aren't using something stupid as a Bee*R limiter which is guaranteed to destroy the oil pump, otherwise the odd trip to redline shouldn't hurt the engine unless you are holding it on redline.

extreme33 Posted October 27, 2011 Author Share Posted October 27, 2011 (edited) Yeah their odd trip to limiter is probably couple times every night. One of my mates Jason doesnt sit on it for too long. Just lets it bounce for 5 seconds and then shifts into third. But my other friend loves to sit on it. Sounds like shit imo.

SargeRX8 Posted October 28, 2011 Share Posted October 28, 2011 I buckle as soon as I hear the first Wapapa let alone 5 seconds. This is the reason I have raised my rpm to 7300. I can still push to 7000 and not worry about hitting the limiter. My turbo didn't fall off. That said I have seen 7500rpm an odd amount of times... Once.

kitto Posted October 29, 2011 Share Posted October 29, 2011 Excessive use of limiter will eventually break an oil pump. Hard cut does do damage to bearings and could also pay a part in rod bolt failure too. Hit limiter also causes engine knock, which can lead to broken ring lands, pitting in the combustion chamber and on the piston. However, a lot of drifters sit on the limiter all day and i personally havn't heard of someone breaking an oil pump because of it. Oil pump is definitely the weakest link though. Having a short nose crank, stock oil pump, old worn harmonic balancer and hitting limiter all the time. The odds are really against you.
