The Ofna is quite literally an NTC3 with upgraded shock towers/diff cases and gear diffs.

Even the visible holes on the diff cases are the same as on the NTC3. . .

I do wonder about the geometry though. . .there is a difference at the rear. AE uses the same carriers as at the front and then a link to a rear stud to change toe (we all know this, duh) but this one uses a traditional 2 bottom pivot ball setup. . .

Anyway, it's a complete NTC3 ripoff.

Default Rear pivot system

Yes it has alot of the same ideas but Boomer what do you think of the rear pivot system... would it work better than what is on the NTC3? I love the way my NTC3 drives and actually haven't had any of the problems with the rear toe that people have talked about but I almost think this way would be more durable.

I believe that it is a sealed gear dif.

Default K Factory fuel tank

Anyone have any problems with them? My car ran alot leaner with the new tank on and I noticed bubbles(tiny ones bunched together like foam) in the fuel tubing going into the carb. On the backstraight, the car started to bog and almost stall once it hit peak rpm. I put the stocker back on, made a few needle adjustments(had to make changes while using the new tank) and after the second tank, the engine went back to normal. I'm going to give it one more try and see if the K Factory tank is causing all this.

When the engine bogs when it reaches peak rpm means that the high speed needle is lean.

I don't like the traditional rear that the Ofna is using. If you change the camber (by tightening or loosening the front pivot ball) it doesn't just change the toe. You're actually moving the center point of the rear IN, thus also affecting the CAMBER. In order to change the toe, you have to tighten/loosen the front and loosen/tighten the rear pivot balls an equal amount else you change the camber and, slightly, the track.

I tested this on my Hudy (at the time. . .) to see exactly how it worked. I used my old GT-4 which had very close to the same system (the GT-4 has a top pivot ball as well).

I like the system that the NTC-3 uses - it's cheaper (two fewer parts to purchase. . .) and simpler (top pivot ball moves the top, bottom pivot ball moves the bottom and the tie rod changes toe. . .). It does require some reinforcement, but since I've changed the tie rods to Lunsfords and changed the ball caps I've had no significant problems with them.

Yeah, I'm well aware of the high speed needle being lean when experiencing those symptoms. That's not what I'm asking about. Just wondering if the new tank is causing big changes to be made to the needle settings.

Anyways, the stock tank works well for me. But since I got this K Factory tank(more $$ than a usual tank), I want to make sure there's no tank issues. I want to use it if possible.

Did you guys mess with the adjustment for the pressure chamber(the inside part of the lid)?

Hmmmmm, maybe it was the cold, chilly weather we had today.

Well, I would expect that you would have to make changes to the carb settings when you change to a different tank design, just like when you have to change the carb settings when you use a longer pressure tubing or when another different new pipe is installed. All these things vary the back pressure that the engine will experience and the pressure of the fuel going into the carb.

In all things, the K-factory tank may cause a lean situation because it equalises pressure better. Just like using a longer pressure tubing.

Since adding the new tank, did you make any changes to the length of the pressure tubing compared to the stock tank? And the little bubbling in the tubing leading to the carb, will that cause a leaner setting?

Anyways, K factory has more new stuff for the NTC3. Like a new one-way and front anti-roll bar.

Does the K-Tank mount any dfferent than the stock tank? Does it have anything besides o'rings under the tank? If not it will always have tiny air bubbles in the fuel line. You guys know this will cause a high speed leaning issue, no matter how long or short you make the pressure line. The vibration issue has to be addressed before you add the pretty, over priced fuel tank.
Adapted the Mugen or Impulse tank into the car for 1/3rd the price and be done with it.

Well said......its really not a secret. Nor the shock tower fix for 2.50 instead of 25.00. But if people want to spend more than they have to, I say let them. Too bad it cant be thrown my way.
