Internals for 700whp?

phunk · 10-21-2020, 04:47 PM

700whp is debatably within the realm of stock engine reliability, depending on how much you actually use it at that power and what you used it for. In the typical Z project setup, 700whp usually cannot be put to the pavement. So even after making that on the dyno, you wont generally replicate that type of load unless doing 4th gear + pulls.

IMHO, I would skip the engine build. Too much trouble and expense, too much room for error. I would take all the money I save and just do an all-premium stock engine setup. Maybe grab a backup low miles stock engine to keep in the corner of the garage, ready and waiting for a weekend swap should the original engine ever fail. Set it up to run 600whp daily (which will already roast the tires 99% of the time you try it below 60mph), and have a 675-700whp high power mode for occasional use when it counts.

When your goal is balancing on the tipping point like that, in my opinion, it makes a lot more sense to just dial it back a tiny bit and spare yourself a TON of money and drama over the built engine lifestyle.

After all the chit I have been through I would say that is a good plan of attack. When you build the motor you want more and down the rabbit hole you go. I enjoyed 718hp daily. It was fun. 600whp was boring to me. Maybe I am just a nut.

I have another in waiting and I will not be building it like I have done with my current motor if it goes bang. I don't plan on running my built motor more than 600 90% of the time. I can tell you from my experience that 550 is pretty damn fast on a circuit track. I only used that power a couple of times because that was to much for my talent level at the time. Hence on the road I dialed it back as well after figuring out that I was as good a driver as I thought I was.
