98_SI_Coupe

Hey guys I have a question for you and its been stresing me all day...I have an 06 Si and today i was at work and started the car for like 5 minutes and 3 or 4 bars appeared for the coolent temp and i redlined it from 1 to 3rd gear..can this do any short term or long term effects?

thanks

it'll kill your motor, drive normally until the car reaches to normal temperature. why would you do something like that anyways.

just a very bad/tiring day lol....well I've only done this this one time so it should be fine no?

imported_SaYjAiBaO

yeah or else you would've had a problem by now. nothing to worry about, just don't do it often.

on vtec and similar engines (lift) you might notice the car won't rev above its 'lift engagement' rpm. on my toyota xrs it will cut-off the fuel at 6200 when the car is cold. Kinda feels like i redlined (sudden loss of power), but its actually a 'feature' of how vtec works.. I would imagine if vtec/lift kicks in (if you have it), yer engine is warm enough.

thanks guys...I made a similar post on TOV and they went nuts! Some saying that my vtec wont open and its one of the stupidest things to do and Im like holy **** I must of really ****ed my car up.

i believe some people say when your car is not warmed up, the vtec won't kick in.... so it protects your engine from abuse....

but again, i never really redline when its cold and actually i hardly redline my car.... only vtec once in a while for the fun of it when i'm bored... but not often i'm bored haha

I would just chill a bit and wait for the normal operating temprature before I do anything crazy with the car.

It doesnt matter how cold or hot yoru engine is. If the oil pressure is up to normal pressure, it wont hurt your engine.

Nova_Dust

I suppose oil pressure gauge is not available in every vehicle, that's why most people go by temperature.

coolant temp isnt what determines whether ur car is warm or not...
it takes a while for the engine components to reach the proper
temp, which is important because metal expands, and the parts are designed to work at a certain temp...clearances change etc...
another reason not to rev a cold engine

Brett

My car redlines at 7500 with no VTEC when its cold, rather then 8300 with vtec. But, i try not to rev high at all when its cold...

well you certainly didn't do your engine any favours, and yeah, you did cause damage, but the question is, will the damage be noticable right now.... prolly not. the damage will slowly get worse and worse over 10 years, and in 10 years compare your car to one that has not been abused, and you will see a noticable difference. but I'm assuming you don't care about that.

anyways, when you're having a bad day, just remember....it's not the car causing you stress.

you can always get a brand new SI

CRXlover

Such a stupid move....oil hasnt fully heated up yet and your beating on it

markpa

Lol u guys make it seem like we drive lambos etc, I really doubt youve done any damage, doing it once or twice.

cibs

regardless of what you drive don't u wanna take care of your car?

if u have a lambo odds are you have more money to fix **** if it goes wrong... as opposed to most ppl that have civics...

98_SI_Coupe

whats up all...just back from work and I was speaking to a co-worker whos into some serious tuning of hondas/acuras and said one time no damage was done...its if it is repeated constantly that it does damage...anyone agree with that?

markpa

Thats what i said, U beat on it everytime u get in it, obviously youll do some damage, but a couple times, it will be fine.

So forget about it now man, your car is A+.
