Turbo V8

[Jon Fedock]

Just my $.02....Either single or twin setup will work well. It just depends
on what *you* want. Performance and response can be the same for either
setup with the right size turbo(s). A single can be responsive and a blast
to drive just as easily as duals can be oversized and performance be soggy
and unimpressive. Just depends on where you have the room in the engine bay
(for me) as long as the turbos are properly sized.

:    Single a lot easier?? The only way that I can picture single being
easier

using

1/2
: the size needed of a single turbo, small (yet very sturdy, and SSteal)
: J-Tubes, I only need to shorted the stock exhaust about 6"  further
: eliminating the need for custom exhaust work, and the only thing making
this
: any more complicated then a Single Turbo would be the necessitation of a

:     Single Turbo....
: 1) Excessive Lag (relatively speaking, ofcoarse)
: 2) Less space, as one big turbo, on one side, apposed to 2 smaller, one on
: either side (remember, its a vette)
: 3) Less expensive/Less complicated exhaust plumbing. (2 banks, 2 sets of

: 4) Much easier to find 2 identical, small turbos, than one BIG one large
: enough for a V8.

:  My next big worry would be the MAF. Blow through or draw through?? and
can
: it support boost pressures around 7-10 psi or greater??
