I'm not sure if this question has been asked before but here goes does an NH straight through work Better than a regular NH. Cheers Colin
Define Better.They do well on a big bore intake,use a little more gas and perform well for some.Others came no real benifit.
Thanks Jack We have rebuilt a straight through to put on the 12 the NH that is on the car has been running for 50 plus years so we are going to give it a check over.I was wandering if there was any benefit to the straight through. Cheers Colin
Colin, I was skeptical of the claim that a straight through works better than a standard NH. So last November I got off my butt and rebuilt the straight thru that I have had in my pile for the last couple of years.
Let me tell you it made a big difference in the power output on my 26 Fodor. It now has almost as much pep as my 25 Touring.
I have a straight-through NH on my '15 Touring and a sway-back on my '26 Fordor. I like the straight-through for its responsiveness. Doing 35-40 and hitting a mild hill, a notch or two keeps the speed up. It has a very good seat-of the-pants feel.
The thing I've noticed about the straight-through is, the adjustment is really sensitive. It's not a quarter turn, nor an eighth. It's even less than that to hit the sweet spot. I found it by running up one of those shallow hills at part throttle and tweaking the knob just a little. Even starting the car cold, it takes less than a quarter turn enrichment. And yes, that's with a new needle valve.
So I vote for the straight-through. Just be aware that they're a little pickier to operate.
