Agreed.
From what I read they ONLY did the S/C swap and what was minimally necessary to make it run and left everything else stock with the other $$ spent on a fancy body kit. Now I've seen in more than a couple places that in stock trim, the VK45 is about at its limits for reliable power (I've seen original VKs at 300K+ in some older Qs-crazy!) which would explain the problems associated with the Keuylian build. Of course tuning will unlock a little more but not much. I've been toying around with the idea of a centrifugal superchargers since other than bracketing, it's a fairly straightfoward install relative to some of the other ideas floating out there. Plus it'd be easier to fit under the Y34's low hood. The problem is you're probably looking at a max of 5 psi or so before things get sketchy (Keuylian's ran at 7.5 psi and higher). That would give some decent gains, but I'm not sure it'd be really worth it for the kind of $$ it would cost to get such a thing made. That brings me to building a lower-compression which actually might be worth it if everything can be made to work properly but it'd be a rather large undertaking because with any kind of big power, the transmission becomes a problem. Getting a built one for RWD would be too hard, but that's more time, work, and $$. I've got a couple more things on my plate with this car before I dive in to an full-on build, but it's definitely something that might work.

I know it'll be a fairly expensive undertaking, but I think it'll be worth it in the end if I can get it to work. Plus who doesn't like the sound of a blown V8?
