Yup...700 has been a few times and generally the results are not good!

Not holding you to anything just looking for personal opinion :tup:

If someone wants the best odds that it will last for at least a few years, probably 425-450 lb ft. Once approaching or crossing the 500 lb ft, the owner needs to be prepared for, or at least accepting of, the worst. Though I believe in most cases the VHR will handle 500-525 lb ft for a long time. But the operator must consider that mechanical wear and fatigue is cumulative and the effects of driving habits and operating conditions can exponentially accelerate the process.

Good read and awesome to see the numbers grow as people try new things and push the envelope a little at a time. Personally shooting for 540-550whp on the bp kit within the next two years!!

Im hoping to hit 500 whp for a daily Z with the AAM TT kit in Australia. Best pump fuel we have is BP Ultimate 98 which I think is equivelant to the US Pump93. Hope mine doesn't give in!

Also hoping to be in the 500's as soon as Sebastian feels like the tune is done enough and I can find a dyno day around here. :tup:

I wanted to know when and engine goes boom after forced induction, say from a blown rod and or piston or something else and it needs a rebuild, does the engine need to be replaced with a new or second hand one then rebuilt or does the one that blew get opened up and rebuilt?

Sorry for the noob question, but just wondering if it matters to open her up before she blows, or wait till it does (if it ever does) then upgrade the bottom end?

It depends if the engine was SWOLE. Aka, a rod came out the side of the block. If a rod breaks, then yes you will need a new block and whatever else got destroyed.

You say new block, is that referring to a whole new engine?

It terrifies me that you've already bought a turbo kit and you don't know these things. You seriously need to come up the learning curve before you murder your car. Start here: https://www.amazon.com/Maximum-Boost...=maximum+boost

That was published in 1997. Prefer something more updated

Einstein published the Theory of Relativity in 1915 - is that out of date? Maximum Boost is probably the most common book I've seen get recommended over the years for turbochargers. Do yourself a favor and research, research, research.

:wtf2:This is just getting to pain to read. Holy F bomb

How about this one - I think it's called "Bumping old threads and asking questions you should have known the answer to before you pulled out your wallet and got in way, way over your head?" That current enough for you? There's a sequel too - it's called "I didn't know what I was doing, so I blew up my car and now I'm making payments on a paperweight"

Then you can finish the trilogy with the classic "Selling a broken car for pennies on the dollar."

:owned:
I've seen a lot of people invest in that trilogy over the years.

Most of the books I have read on going faster on the track are "old", why, because the principles, which is what I was learning at the beginning are all the same. Those were early 90's books, but nothing has really changed in principal and terminology. The only change has been better data logging and video recording equipment allowing you to see and improve faster.

Savage!

Then there's a prologue to the trilogy. "Should've just researched and the next three books wouldn't have existed."
