i know on normal turbos (ie not VNT) the GT30 (wich i think the GT37 is the equivalent to) and GT40 combo has been done. here is a example on a UK evo site (very good).

dont know if it would be as usefull as say a GT35/40 on a larger CC (like your V8s) as i think it could be restrictive at the top.

thanks Chris.

You would definitly need twins for the 37 housing. it flow slightly less cfm than the 35 housing, but is capable of very high pressure ratios. All day long( diesel). I would use 2 as is, mounted up back, no intercooler. 2 oval tubes ( around the same area as 2.5inches) running down the belly. Then I would use a secondary rail of methanol. 87 in the tank for atmo use (cheapish) then Methanol alcohol in large doses for up to 25-30 psi. For a 55gal drum of methanol it's $128 here http://motorsportsracingfuels.com/product_8.html.
Ive decided thats what I'm gonna run this year instead of an intercooler.
