I have bothered a few of you via PM with the following question but here it goes for public thrashing...

I knows twins rock but at this point for the sake of argument they are not in the picture. I am in Denver at 5k' altitude. I want to to run the biggest single charger I can. I don't tow, don't lug it around, and I have a 5sp. With current setup my 35/12 lights at about 1500-1600 rpms but I can't keep it cool as should be expected. I have ridden in dbook"s 01 ho with KSB1 that lights around 1700-1800 rpms with super mentals and drag comp. Although it still get's toasty pretty quick the higher spool up is not hardly noticable IMHO. I would like to try some mach4s and a full B1 and wonder a few things...

Where would that turbo light up?

How much would spool up speed be lowered with a cam?

To what degree would a B1 cool mach4s at this altitude?

I can make my mach2's smoke now if I want but I can also drive pretty clean just paying attention to when I step on the go peddle. I guess I want to avoid something that flat out cannot be driven period without crazy smoke and also not sure that spool up over 1900-2000 would be that much fun either. Thoughts & Opinions? Thanks
