I don't post alot however seeing its on TR's share my setup. Years back helping out with friends cars/drag with carb tuning I decided to 'freshing" up a "street/strip" combo. A 30 over 427bbc with Edel roval port heads, comp extreme energy solid cam, with 10.75 comp. Then I wanted to do a dyno test comparison between edel rpm air gap and the dart single plane both where done with a BG mighty demon 850dp (The dyno guy was surprised at how well the single plane intake had done). And once I had a pair of holley 650dp's done we then ran the weiand pro-ram (eye candy is what the dyno guy called it
). Now this is from memory... the air gap 525hp@6400, Dart actually "peaked" at 6300rpm with 540hp. Now with the TR setup he ended up running flowmaster mufflers for the noise and admitted it would take some power away, It made 540hp@6400rpm, what we noticed was that the TR and the air gap were within couple of HP/TQ from start of pull 3500rpm to about 5000rpm then the TR pulled away and equaled the single plane but still carried thru where the single plane was going down (Now the dyno guy is a believer). There is a little more time setting up a TR however taking the time to tune any combo is key vs bolting on and going.
Its funny that your story is something I have heard a few times in the last couple days...the guy i got my tr from said the same, he had dyno'd a couple small cube motors, with
Single planes and big solid cams, and the tunnel ram actually had slightly higher trq#'s or equal from 2500 up, and several times actually equaled a good dual plane until 5500 where the TR walked away.....the lad with the beaumont (Canadian chevelle
) I was speaking to today said he went from 12:00's to 11:70's right off the trailer with no other changes but a swap from a vctr Jr and a 750dp to the weiand and 2 600vs 's. So I'm hopefully for sure...
