For the record,....just as soon as two BMW twins free up from a warranty engine, the Monster goes back to forced induction.
It may be a month, it may be a year....all I know for sure is that it will happen.
The twins on our 4.4L v8 are V band attached, and internally waste-gated. The "free" aspect, and the notion of getting a pair of water cooled, ball bearing turbos rated for an engine my size is the attraction, and the reason for the decision.
I won't change the ITB part of the equation though, I like that, and I wont change the glass top either...I'll keep the glass top on with some kind of strap system.
It also wont be a "this year" project despite my acquisition of the goods......The reconfig will probably be several months knowing me. The fact that BMW wastegates are vacuum actuated instead of the normal boost pressure actuated method, and the plumbing into the water system, and reinstalling my rear mounted cooling system will be the reason(s) for the time.
In the mean time,...this will be the summer of N/A.
It just seems that the engine runs restricted,...and like the new title says, I now have over 12" of throttle plate opening that has to breathe through a 3" hole.... That has an 18" long tube attached ,.....that has 3 90 degree bends,....that is capped by a conical filter.
I lay in bed wondering...........how can all those wide open throttle holes breathe independently when forced to get it all out of one 3" opening.
Now I know that all engines typically breathe through a 3" hole or less, and work just fine,....but when it comes to optimizing an ITB setup,..........are you negating that benefit by forcing them to breathe through a common opening?
( obviously, the simple answer to that would be to remove the airbox at the dyno,....but the dyno session was cancelled due to the operators vacation)
And my seat of the pants dyno will lie to me.
I've got some "free" money that will let me re-purchase a water meth system. It will be how I plan to cool and control detonation when its re-boosted, and I'm not afraid to integrate it into the N/a engine right now, for the sake of the potential weanie assed power gain I'll get from the meth. So,..I'll be buying that dude in the next day or so....wherever the price is best.
I have a BOV still, all I'll need will be a reconfig of a short cold side, and of course......figure out how to mount those turbos on the headers...(that I made turn up,....in anticipation of having to do exactly what I'm contemplating)
So,...Call me a flip flop if you want....Tell me I told ya so if you need to.....I'm glad I converted over nonetheless. I'll still have 1 of 1.
