I think you're approaching things like a racer building your one and only track car: find what has been proven to work in your class or similar classes, do that or something very similar. Don't waste time or effort on things that aren't likely to work. It makes sense, and is probably the best mindset for most of us.

And I think Rob approaches some of his cars like a programmer or a science student working on a side-project: try something different because you wonder how it will turn out. You might get lucky and exceed expectations, but there's not much pressure if the results are sub-optimal. Perhaps one car has the wrong turbo because one of his industry contacts asked if he wanted that particular model for free and he didn't get any alternatives. Or perhaps he picked the wrong one for this iteration of this car because he hopes to change things around and use it for another car or another iteration in the future.

well it’s a public affair by choice and we all have an opinion; right?

fortunately can FFWD through to the 3 parts that matter.

Which are pretty awesome and good for Rob to come out on top 3 for 3.

This is actually the most accurate assumption. I have no formal or contractual requirements to use any specific product. Ive made quite a few 2 rotor missteps but they are also much easier to see as so many people have them. 3 and 4 rotors are uncharted territory. I do strongly believe my twisted approaches to the 2 rotor have taught me some amazing things to extract more hp out of the larger motors. My strategy is basically to try weird **** on the 2 rotor and apply what i learned to the big ones. For example last august i had a horrible month with the c5 trying different things, but it taught me so many things about fuel injection timing, individual rotor tuning with both o2 sensors and egts amongst many other fine details.

I blew the synchros on the c5 3rd gear or i would be beating the absolute **** out of it right now. I love that build dearly. dont have time to dig into it with all the plans sadly. Hiring another mechanic to help with the maintenance type tasks so i can focus on the big pushes and improving my driving.

well don’t take anything I say too much to heart, my thoughts don’t amount to anything when it comes to making your own choices for what ever reason, as we all should.
