L67 specific question

Curtis · 04-11-2007

this may sound dumb, but just wondering...
I have the egr deleted and the block off plate for the intake looks like maybe a possible place for an after s/c injection site, has anyone tried this or is it just far fetched?

if u mean the hole where the EGR hose goes into the lower intake manifold, the answer's no. the reason is because if u do spray it there, it will be an uneven distribution of alcohol entering the cylinders. the best place would be is having at least 2 nozzles on each side of the lower intake manifold. that means drilling 2 holes on each side for equal distribution.
