I ordered a Torker II intake for my Maverick and it arrived today. The front and nack runners look small and restrictive, while the middle 4 are wide open. Had anybody used this intake and had any good or bad experience? I probably should have got the victor jr.
I like my torker on the '74, though the motor is totally stock except ported heads & roller rockers. It was on my '84 Mustang GT 5 speed, worked great from idle-5000, which was where the cam and heads signed off. I would think that an RPM air-gap would be the best choice for a street-driven car, with or without nitrous. It gives a powerband from about 1500 to good-lord-knows how high (dad runs his up to about 7200) with excellent mid range and bottom end torque, which is nice with "only" 302 inches (or in your case 347). It'll give up about 15-20 HP to a Jr, but you get all that back in the lower revs. Also had a Jr on the Mustang (with the newer motor....similar to yours except 306 inches) and it was "ok" but the lack of torque from 1000-3000, where most driving was done was old. Also, the mileage wasn't too great at 18-20. It pulled HARD from 5000-6200 where the roller lifters & valves go into float, but I RARELY run it that hard, even a once-a-year trip to the drag races. I swapped it for an old RPM I had laying around, tuned the carb/ignition curve and am now getting around 32-35 MPH highway, 22-24 city, plus a MUCH better low end. It doesn't pull near as hard as the Jr. did from 4000-up, but oddly enough, it's faster at the drag strip than the Jr. was (gets out of the hole and through 2nd & 3rd quicker). The difference was the Jr ran 98 MPH and the RPM runs about 96. Also, the Jr needs more fuel at low revs (rougher running...crappy mileage) because runner velocity is much lower and needs more fuel in the airstream. My personal opinion (FWIW), I think an Air-gap or even a Stealth would have been a better matched intake for the engine you have. The Jr "wants" a hell of a motor in order to perform to it's intended usage. Hope that gives you a real world idea of the differences between the Jr and the RPM. The air-gap is a little higher-strung than the old RPM, but still works good at the bottom of the tach. Let us know how yours works out!
That is alot of comparison with the jr. but not sure what your opinion was on the torker. I am taking off a Stealth that never did seal right, it has a high spot from the factory and after having it milled I had to use thick gaskets, SO I wasn't going to try the stealth again even though it might have been a better match. Air gap was my first choice but price scared me off. Vic jr. just seemed like too much rpm for me. I also have trick flow heads if that makes a difference to which intake you all think I should have got.
I called jegs and the guy said that if i got the perf. rpm package along with the heads, i would have about 300 at the wheels. I dont see how this is possible. Mavaholic put afrs on his mav and he just has 300 in back. -Todd
I ran a torker II on my old engine.....basically stock motor with gears and open exhaust it went 7.70 in the 1/8th.
The mustang runs 7.99 with stock iron 351w '75 model castings. The mav ran that with the C4 and the same basic heads as well. With those TF heads you already have, I would use the Torker for now, since you already have it. Later on, I think you'd be better off with the Air-gap. The torker I had worked well...but it was no comparison to the old-style RPM I have on it now. BTW the throttle response with the torker was significantly better than the RPM is...I guess because the runners are smaller and provide better velocity.
ryan what kinda cam you running and converter? i use to run a torker II ... never did like it! i soon swaped it to the victor jr it ran better... however the Victor was too much for the car... why cuz that manifold needs a motor that revs to kindom come! so then i switched to the RPM... way better choice! i'd trade it back in.. depending on what kind of cam your running along with the heads.
my cam is a Lunati 51014, it has intake lift of .500 and exhaust .510 and intake dration 284 and exhaust is 292. It makes power past 6000 rpm. On my desktop dyno with my engine setup, switching form dual plane to single plane intake takes it from 450 to 500 horses with the single plane. And the power band peaks around 6500. Of course there isn't an option to chose which single plane intake. But man if it even comes close to the estimated 500 hp I will be one very happy man. Hopefully dyno tune will be next month.
that lunati 51014 cam is a great running cam, though it won't pull to 6500 (naturally aspirated) and still make 500 HP. It's actually pretty mild for a 347, and I think a vic. jr is too much manifold for such a mild combination. It'll work...and work well, but street manners aren't so great, espcially with an automatic trans. Also, most hyd. roller engines I have driven start floating valves at around 6200-6500. I've seen dyno graphs where float affects HP output by 50-150 HP depending on how severe it gets. Adding a rev kit drastically improves float...at the expense of some more complication to the valvetrain parts. I think an RPM or Airgap is the best choice in your combo. Remember...the Jr. is designed for 12:1 compression, 7000+ RPM race motors. Even my old 12.5:1 306 didnt like it below 5000 RPM, but man did it come alive on the top!
What would be the best setup for 300+ at the wheels for a 302? the jegs guy said the rpm kit with rpm heads would be perfect with a better ignition setup. -Todd
