Sasha has discovered with the boosted performance kit that running over 500 whp even with the 340 lph pump the stock wiring could not provide stable voltage to the pump, thus your statement makes sense...he now provides a custom made fuel pump harness.

This topic has been popping up more frequently now, and the numbers also have been increasing.

When I got into the Z forums back in 2011, the general consensus for ultimate reliability was to keep it under 500whp and 400wtq.

We know the stock block can hold 600whp+ 500wtq+ for several dyno pulls....but who has been doing this over an extended period of time. There is already a few blown at these higher levels.

I haven't seen too many threads about that. Who's lost a motor from making too much power?

As much as we've seen the 500/400 numbers tossed out there as the limit, there's plenty of guys running substantially more than that without issue. The question is how long will it stay together. The 600+ guys aren't on pump gas, so they've got a bit more leeway but I can't imagine that being good for the motor's longevity.
