These results have convinced me to stick with a turbo (not as
much detriment from back pressure as I thought),
Hi
Dave,
I was always under the
impression that the turbo exhaust manifold itself is restrictive, and far from
ideal from a scavenging standpoint. It might be just as restrictive as the
turbine housing, which may lead you to a false conclusion. I
still strongly suspect this is where Paul's power is going.
The concern about
manifold backpressure goes away to some extent when you bolt the real turbo in
place, since the turbo more than makes up for the restriction.
Installing the T04B, and a better flowing exhaust manifold will be like hitting
the jackpot.
Cheers,
Rusty (still turbo
free)
