We have setup custom maps with the boost controller and tunes to allow them to cycle through to each boost set point with one touch of a button. We went a little more in depth with each controller and that mapping from UpRev. For the sake of keeping things a secret for our tuner, I will not go into the specifics of what and how we do it.

Thanks, Tony
So now it's on the owner to be responsible and dial back the boost? That's got to be terrifying. You never want to go back to low boost.

We do not give them the car back with 100% in it. About 65-75% and they can work it up from there as they feel comfortable. We educate all of our customers on how to properly use the boost controller.

In the end, it is there money, they are big boys and girls and they have to choose to be responsible. That being said, let's give people a little more credit once they have spent this kind of money to actually respect their investment/car and our time that has gone into it. So far, so good! That's the kind customer you will always want!

Thanks, Tony

Here is the bottom line...Efficient parts, adequate fuel pressure and proper tuning will allow you to push the envelope higher. Sure, is there a point where too much is just too much for the stock block, absolutely. That being said, up until our kit NO ONE was making these numbers on our psi levels, and to add, most people do not bring adequate fuel pressure to the equation. Lastly, we have one hell of a tuner who stops at nothing to make it perfect. It also helps that he tunes the Z34 almost every single day.

Remember, when we set out to do this we wanted to build not only the baddest kit around but it needed to be the most efficient. The results are a byproduct of the design.

Thanks, Tony
And you've done that, and then some.

Now we're just getting curious where the limit is now. Everyone thought it was 450 ft/lbs or so. Now it's 100 over that. You've got guys knocking on the door of 700whp on a bone-stock motor. That's insane. I'll be the first one to run a victory lap if it holds together, and then I'll add fuel and turn up the boost. I'm really glad we've got people who are willing to gamble with their wallet that the motor can make big power. That's how we find out what it can really take.

I'm giving them plenty of credit, but I know how addictive boost is.

I have not put together a full-on build thread yet, but I will be shortly. I think it's fair to say the abuse I'll be putting the car through will be as thorough a test as anyone in terms of reliability.

That being said, I truly feel that most of the failures people have seen in the past can mostly be attributed to 1) heat 2) fuel, and 3) tuning. Not raw power. Are we approaching that point? Probably. But just look at the bottom end of this platform. It is no joke. Failures at ~500hp are not being caused by power alone.

I'll save a lot of the gory details around my goals, mindset, and decision making process for my build & review threads. But said another way, I went into this with eyes wide open. If it does fail, its because I chose to push it that far. This is why I have a spare short block being built in the meantime. I put my big-boy pants on before we started down this path.

Tony, Dan, Seb, & Charles held up their end of the deal (and considerably exceeded all of my expectations). Soon it will be my turn

Well said. That's how you have to approach pushing limits.

I'll be the happiest guy in the world if you figure out that the motor will take 700whp on a stock motor. If 700's the new limit, then I'll add fuel and retune and go looking for 600whp. Time will tell, and I wish you guys all the luck. I'm not trying to be negative. The results are fantastic. We're just curious where the new limit is, since the old one has been shattered into tiny, tiny pieces.

Every F.I. car has left with more power than the previous one. That's saying something.
