how high can you rev an A series motor?

[fijisac]

well i just wanted to know how high you can rev a 3g, i know the redline starts at 6200 RPM but my friend went up to 6500 RPM before shifting :eek: so i just wanted to know how high you guys rev ur 3g? my 3g is a lx carb with a 5 speed trany

[Bassmastry101]

not sure, i wouldnt go far beyond redline. good luck to his piston rods all i can say lol

[MessyHonda]

they rev to about 6800...but at that rev the motor is not making power

[russiankid]

Its not really the issue with the pistons its more of an issue with the valve springs being to weak at those rpm's. This is why people who plan to rev high upgrade the valve train to prevent damage. The A20's are really strong motors if you take care of it and don't be stupid when revving it. I usually never go over 6k rpm's.

I know Tdurr has a set in his A20

[Tdurr]

i revved mine to 7200 before i had the springs. in 1st and 2nd a few times(wasnt paying full attention to the rpms lol) but it was terrifying when i was up there. U can feel a powerband loss at 6800ish anyways. Whenever i was trying to get somewhere really fast, i'd shift at 6800, but normally at 6200-6500.

i remember seeing A20A1 rev his LX to 8 grand. wayyyyy back in the day.

Damn at 7,200 doesnt cut off at 6,800 :eek:

[Tdurr]

^^ not mine. My fuel kill*i think cuz of the violent shake of the car lol* was at 7200.

[Rendon LX-i]

holy shit

[AccordB20A]

I had a carbed A20A2 that had a fucked cam gear key and the carb ran a bit rich and it pulled all the way to 7krpm fine, never had an issue with it

[Tdurr]

holy shit

wut? :kekeke:

[A18A]

ive had a old a18a up to the end of the tach which stops counting at like 8500 or something.

yeah mine was 7200 as well i took it up there alot too ^_^ even did it with a blown head gasket!
and according the shane everything to that engine was in great shape still just needed the gasket replaced :omg:

['A20A3']

Her*.

you're right.

and second, yeah my fuel cut is like 7. it bounces off of 7 crazily.

true that, i only hit 6200 if im really pounding her, but the only reason i mentioned pistons is because my buddy has/had a 98 prelude with a h22 racing motor and snapped a rod revving wayyy too high at every shift.

He laughs at my car because its old, i laugh at his car because mine still runs damn good :D

[Rendon LX-i]

welll i only take it to 6,000 no point when your boosted anyway...all your power ends there

[LxAcc510]

shiiiiiiiiiiit with how weak i feel my car is compared to driving my dad's bmw i'm scared to go over 5k lol :nervous:

Mine hits 8k rpm but thats with modded valve springs and fully bluw printed engine, it can go higher but needs a better exhaust manifold and system first, mate of mine over revved mine my mistake once hit 10k rpm roughly and engine still survived with my setup so they can take the revs but for how long who knows! After 30k miles mine decided the rod bolts wanted to come off so if you do like high revs make sure you tighten them up a little higher and use thread lock on them!
