[s-cars] NOS

[Ray Tomlinson]

FWIW, Tim McLean at Northern European Automotive in Concord, NH, ran a NOS
direct port kit on his 1.8t Challenge car.  The kit uses dual, direct port
injection into the intake runners for metering two different shot volumes,
and comes with all the lines, regulators and two different sized bottles.
He is going BIG on his next motor, possibly with some design help from some
tuner that builds 900hp GTI's, so NOS is apparently not necessary, and he is
willing to part with the kit for cheap.  Give him a holler if you are
feeling adventurous.

Tim is also selling a polished intake manifold that is ceramic coated for
next to nothing.  I have seen this piece, and it is quite nice.

No personal BTDT but I can share what I've learned about it.  When used
correctly, NOS can actually be an excellent mod to a turbo car because
the NOS will actually lower the temperature of the charge air.  The key
is being able to supply enough fuel for the amount of NOS injected, as
well as distributing it evenly in the engine.  Holley has a decent tech
page on NOS here:

If I was going to setup one of these systems on my car I'd probably use
their NOSzle system which allows you to inject nitrous and the
corresponding additional fuel needed directly into each cylinder:

hopefully others out there with BTDT can give you some more info.

Later
