Very nice. Glad to see something more substantial than we saw on the stock NA car.
What PSI were you running? And any plans to run a test with higher PSI?

I only took a quick glance and I totally missed that! I thought that was the torque curve at first.

IC, very nyce indeed but with a 3.5L and no headwork the gains would be quite less right???? How much do you think would be the projected difference?

I saw that, but its low boost, on a TN kit, and a stock motor alot of variables there that will change the outcome.

Heck, I'll do one when I receive it.

So what if hypothetically my grandmother had *****? Would she be my Grandfather??
Seriously, there are way to many, "what if this" "what if that" comments.Look at the before and after tests. THE ONLY THING CHANGED ON THE SET UP WAS THE PLENUM. The plenum was the only reason for the HP increase in their testing. I tmakes power over a stock plenum, period. To speculate how much on particular applications is silly..
Nice gains..

Thanks for the research IP. That is an impressive gain.
The only thing I would like to have seen was a 3 way comparison - Stock vs. Spacer vs. Cosworth. There is no question that the Cosworth makes power over stock, but now we're left to wonder how much more power it makes over a modded stock plenum. Simply so we can figure the cost / benefit ratio.

I am just glad I ordered this thing before the stampede starts.
