I did a paper on those diverter valves in a business class......it would be cool. Well, once I'm rollin out more than 175 rwhp that is.

- 12mm VE w/custom dynamic timing. Custom fuel-pin, Custom DVs. THD 5x.018 flowhoned to 7.2ltr/min (liquid) w/high pop-pressure.
- Real cold-air intake, Big IC, 3" plumbing, twinram feedhorn, ported head, 188/220 cam, 3-piece manifold.
- S362/14 over an HT3b (too small).

At 1800~2000RPM, the smoke goes away, and you get heavy in the seat.

From a cost standpoint, is a big single w/diverter up to par (probably just "close" to par) with twins? I know plumbing gets expensive with twins right?

I think on ve it would likely be just as good since there is only fuel for ~500hp. So a turbo that would normally be awful to drive would spool easily and have lots of top end air. Same concept as compounds. I think one of them 67.7 with a spool valve would be great. Or a 471 with a .9 t4 might be fun.

Awesome. So your getting a diverter when 8)

I wish I had one already but they're bloody expensive. $600+ seems normal.

How much machining fab would it take to make you think? Hard part being the boost referencing I guess?

I think the fmw 364.5/73/.91 T4 SXE would be a fun single with a spool valve for a ve. Same compressor exducer as the 63 wheel, 82 lbs/min. That's as much air as the old S366. New version of the 73/80 turbine wheel is mostly unclipped, and is supposed to spool better than the old clipped version. A little head porting, a mild cam, and a T4 manifold with a spool valve would probably spool as good, if not better than a S362 on a stock motor, imho. Or..the 369/73/?? Does close to 100 lbs/min, same compressor exducer as the S366 SXE. 8)

Would 400 + hp be needed to spool that setup?

From what I hear the new 80/74 turbine wheel is a lot better. I'm not sure the spool valve would even be needed with the 64sx-e. Though when you consider the s480 I run as a single on my 6.7, lag is something I don't really care about. I think when the new sx-e s400's start hitting the market I might pick up the 72, and 76 (the 72 apparently will outflow the current 476, so I'll try it on jaeger to see how it does as a single with the big displacement then see how it is as a primary on The Roo Hunter)
