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?

Don't floor a cold engine - It's basic science, things shrink when they're cold and expand when they're hot, if your engine shrinks around the piston and piston rings then obviously there is increased wear as its a whole lot tighter (probably not far off from seizing and you notice how the engine feels heavy before it warms up), this in combination with oil not being at operating temperature will provide less lubrication, hence oil has 2 parts to the viscosity rating - one at cold one at operating temp.

The rev limiter - It's made up of many factors, For one theres no point revving past the redline with stock cams, Look at a dyno curve with stock cams and aftermarket cams and you'll see why -- it's like revving down, power is at the top of the curve, revving past the curve is essentially decelerating. Secondly in order to keep producing power in the high revs the engine needs to be high compression (the FE engine is not.) Third and most importantly since there is no point in revving past the redline (and especially with an FE engine) the engine internals are not designed to cope with the extra stress -- as mentioned balancing and all that crap, bore and stroke ratio, total amount of stroke, etc. These factors come into play well before any fueling issue should arise unless the fuel filter is clogged or something.


There is no reason why you can't floor your engine from 0 to the redline if you look after it, nomatter what it's age but hard driving on a cold engine is a sure fire way to f*ck it!
