Sorry, if this is a late post on this...Bob, did you really mean 25% fuel
mileage lost by blocking the heat riser? 25%? So if I get 20 mpg and block
he riser I would only get 15 mpg? My sense on blocking the riser is to cool
the manifold which reduces the charge air temp a little bit. Drag guys now
regularly ice down their manifolds to get the densest air charge they can.
They may or may not use a cool can to cool the fuel...all this in an effort
to make more power and not economy of course.

And a good 2 cents worth it was! I wish we could all put our heads together
and find a solution that works for mileage and power before the fuel police
come around and kill our cars...
mayf, the red necked ignorant desert rat in Pahrump, and where the hell is
Push anyway...
