How much power do you think is safe on stock internals?

Red__Zed · 05-29-2011, 11:44 AM

It's a slightly heavier load on the engine at speed. It's not terribly rough on it. If your car is actually fast, you will be hitting high speed in the SQM, and definitely in the SM...

My last drag car was doing ~160 at the end of a SQM. Seemed to not be that much rougher than when it had been trapping only 145 or so.

We aren't talkin bout your last drag car, we are talking about a boosted 370z with a stock block please keep the car at hand on discussion thanx.

You are making the claim that a high speed pull is somehow significantly rougher on the engine. I'm telling you that with several rebuild of my F20 (F25?), several hundred drag passes trapping 145 treated it about the same as trapping 160, as well as doing some standing miles.

Pretty sure that is relevant, unless you think the VQ is different in some way...

Nismo370 · 05-29-2011, 12:25 PM

You cannot compare to different motors, and I'm going to leave it at that.

So getting damaged by high speed pulls is a unique characteristic to the VQ?

I've been running around my condo holding my supercharger making boost noises, I estimate I'm making somewhere around 600rwhp and my dog has seen me do numerous hard launches from the living room to my office. So far I'm a bit tired but theres no signs of compression loss and my leak down is consistent at ~8% across the board. I've sent out a urine sample to blackstone to examine for any metal shavings/signs of bearing failure. In conclusion everyone needs to chill out.

In my draw. Believe me they are not worth posting, the best time I could muster up was a 13.3 @ 119. Track prep was horrible, I had bald tires, and had massive wheel hop 1st and 2nd gear. Only did 89mph in the 1/8 and picked up another 30mph on the 2nd half of the track.

You should take it out again with some better tires and maybe a better track
