Quote: Old wives tale, tunnel rams are not hard to tune, you just have to think a little different. I totally agree. My TR is actually easier to drive, stage, foot brake or trans brake.

But I've run more than few dyno tests where the tunnel ram is a dog. Some of the old school tunnel rams are very weak when compared to a good single plane intake.

I have one for my W2 but sadly if I do the 440 in the 66 Val wagon now I doubt I'll get to use it....I'd like to trade it for a standard port TR since a tr set up will actually fit under the Rocky's hood WIZE World's Quickest Diahatsu Rocky (??) 414" Stroker Small block Mopar Powered. 10.84 @ 123...and gettin' quicker! https://www.youtube.com/watch?v=-mWzLma3YGI In Car: https://www.youtube.com/watch?v=PjXcf95e6v0

I did dyno tune the tunnel ram, ended up getting 652 hp and 590 tq. I think my engine is stout enough for the tunnel ram. 440'', 660 roller, 13.1 comp.......

I have a 493 at 12 to 1 comp with OOTB Indy SR's with a comp 262 575 with 1.6 rockers, plenum ported Victor intake and 1050 Dominator. Would this engine benifit from a TR?

I believe that is the main advantage, along with usually less restriction at WOT. There is always an exception(G3 Hemi?) though to any rule, or so it would seem. 8..603 156 mph best, 2905 lbs 549, indy 572-13, alky

I bet you'd be at least a tenth quicker with a tunnel ram and the right carbs. Carbs are key, I ran two 750 Quickfuel tunnel ram carbs and they were perfection right out of the box. 8118944-100_1925.jpg (566 downloads)
