Title: Drop in boost.
Post by: scotsjohn on June 10, 2011, 10:01:35 pm

Fitted a new camshaft recently; a Newman fast road spec. I was getting 0.9 bar prior with old standard cam, now seeing 0.8. I haven't got the figures for this cam, but I was wondering does increased dwell drop the inlet pressure.

IIRC when my schrick cam was in, my boost dropped as well. Although i had a bvh on it when from around 15psi to 12 psi. At 7k it read used to read 18-19 psi and it then it read 15psi.

Expected because more air is getting consumed by the engine
