Custom ported and CNC throttle bodies, upper and lower manifolds by Synergy Composite

I didn't test a ported VHR intake manifold on the VVEL engine neither on the HR engine.

my last testing was in 2012 on the HR intake manifold (barely ported) on the VVEL engine and there was a lot of gain below 7000rpm and pretty much the same 7000 to 7500

then I did a separate test on the 2 different size of TB and there was also a good gain there ,, but wont do **** if you still have the OEM air box since you need a bigger MAF tube.

Most of that stuff is in the first few pages of my Journal

Right now the HR Intake manifold has been port matched with the lower intake manifold for over a year now. but I haven't done any true testing on the dyno but did seen in avg more air going in (Maf Voltage avg.) during street tuning
