    Question tunnel ram

    what are the potential gains of running a tunnel ram on a fairly stock engine, besides looking really cool..., how do they work?

    I am not a racer, don't care about leaving some HP on the table, don't care about spending days on a dyno, don't care about that last 300 RPM or so, and only run tunnel rams because that's what hot boats are supposed to have!!!

    Mine actually do use them however.
    My opinion is do it, there are some fine boats out there with 2 450s on them.

    OK TN, that was pretty good.....


    It's been years since I did a TR on a stocker, but agree it's not gonna add much if anything. Put a TR on a stock 455 olds in a T-Bucket years ago for a buddy. Man what a pile of crap that deal was. The article may be applicable to stock applications as well but not on a real performance engine. Once you start getting up in HP a bit, a TR is nearly always good for 30-70 HP over a single 4-barrel in a 850+ HP motor. It's been tested on dyno's and tracks a ka-jillion times. Not sure what it would do on a motor in the 500-800 HP range, but bet it would help there too....

    Heat shield? 455 olds

    Hot Rod magazine did an intake manifold test some years back on a 500+ hp smblk chevy. I think they tested 12 different intakes .... a couple of TR's they tested out performed the other intakes from mid-range to top end. They did very well on an engine that was well built but in no means a super hi-performance engine.

    I'll see if I can find a link to the article.
