WOT at 182K, effects Options

[6G96GT]

So I have a very solid block with 182K on it. The head was fully rebuilt several months ago. My car runs great, doesn't burn oil, and has great oil pressure. I was wondering...how much WOT driving can I get away with? Not the floor it from a dead stop either wot. I usually take off at an average pace and then WOT it from 2nd through 4th. Is this going to kill my motor quickly?

The harder you drive it, the more wear you put on it. at 180+k id say there is a fair bit of wear on it already.

[Euphoria]

Just do regular oil changes, aslong as you don't drop the clutch or do terrible gear changes, don't keep thinking your engine will die when your floor it.

i do it at least once a week before a gas fill-up

had my head replaced last june @184k now its 189k

Good to know, I had my head rebuilt this past march/april with t-belt, w-pump, port and polish, and full exhaust. It's built to have fun (mildly). I just want to know I can actually 'have' fun without killing it. My block runs at 51 PSI on the highway. That's good, so I shouldn't worry about it.

well just dont over rev and WOT when the engine is cold. make sure its in operating temperature

Why's that...I mean I know that applies to turbo engines but ours too?

its in the owners manual

of course you dont wanna stress the internals. imagine running WOT with your lubricants cold, your engine and gear oil dont reach the operating viscosity thus making the internals work a lil harder.

what the heck is WOT lol

[SwissFerdi]

Wide open throttle.

Alright then, that's what I'll do from now on. Thanks!

Rev limiter?

Rev limiter yes but isnt the rev limiter pass the red line?

idk what rpm exactly it is. but IMO try not to get to the red line as much possible.

Mine starts right at 6200, the exact start of my actual redline.

I've always wondered, if you up injectors, can you successfully up your rev limiter?

ummm i hit 135mph on the I-15 south from fallbrook to san diego all i had was a air temp mod, cold air intake, and exhuast(2 1/2 inche pipe). no fuel cut off occured just the rev limiter kicked in and wouldnt let me pass 6,800 rpms

this is what i've got from searching around.

not sure if injectors have a play in the rev limiter but ecu maybe.

In theory,
The rev limiter is only there to make sure that your engine isn't being starved for gas at higher RPMs which causes a ton of friction/overheating your engine/frying your rings. If you put on a better fuel pump, larger injectors, and re-tune your ECU, in theory you should be able to up your redline. Correct me if I'm wrong.

being starved on gas?? idk about that.

here's a wiki link might be helpful

http://en.wikipedia.org/wiki/Rev_limiter

if you can, could you put up an actual video from your celi?

Heh,
Talked it over with a friend, I was completely mistaken. Red lines are there for a reason, the crank, bearings, wrist pins, etc. are only balanced up to 6200 or whatever your red line is. When you go over this, you have a much more likely chance of your engine becoming un-balanced and cause major wear to your internals.

I actually now know exactly why the rod bearings went out on my bike, I somehow got my rev-limit upped considerably and would run the engine extremely far into redline (roughly 2000rpms over) and then shift into the next gear. So lesson learned, don't ever run your engine past red line...

woah thats crazy 2k rpms over!!!

[6G96GT]

So in theory, if I had my block rebuilt and then had the crank polished and balanced, then I could run over the redline a bit right?
