Mine makes that at 15 psi but unfortunately, as you know mine's a stock block. 7k miles. That would be about 5 years for me

Making that power and never using vs making that power and using it all the time is a huge difference. Open deck or built bottom end with Hg won’t last long period. It’s hasn’t for the 10 plus years the VHR has been out. Now we do have some unicorn build’s amongst us but the negatives still
Outweigh the positive. If you’re so confident start entering 1/2 miles races and run them
At full
Power.

Yeah, it is heart breaking. But we can't change it.

A. More money needs to go into R&D to overcome the junk cast, B. Swap a VR38

Maybe so. I may just turn it down to 18psi which is right at 800whp. One thing is for sure. It will be off the chart under the hood with some new bling.

If Z1 would take that million dollar COVID loan they got that was forgiven and do something we all need with it that would be good. You know our tax money is paying for that crap. Rich getting richer and the poor are getting poorer.

There's no reason why an open deck block with hg can't last at 700whp. Yeah, maybe using that power all the time, the longevity will be shortened but how many people are using that power all the time.

It makes no sense for me to do 1/2 mile races. At my power level, I'm not going to set any records. I just want a strong running street car without spending 25k on an engine

I used 718whp on my first motor ever time I got behind the wheel which was every day. 7k miles and it was done. Stay in the 6xxwhp range with your stock block and enjoy it. Following in my foot steps is not fun. I enjoyed
my first build the most. The car was a ton of fun. If I could go back there, I would.

I agree. But saying 800whp is reliable on any form of open deck isn’t true. Most people who say that never run at that power level. More of a status thing, saying I made that power. 700whp is about the limit of what a oem block can handle. Soho proved that after a year of racing before it shot a rod out the block.
