A single wheel at the back of the car could pivot the rear tires off the surface. To leave off idle you must have enough power to launch the car without climbing the ring gear and enough weight up front for balence. My wheel was 48" back and spring loaded so that it would not bottom till the front raised 12" and carried 140# on the nose. Leaving off high idle the front would still rise 5" and carry for 20' and never touched the wheel, as it was there for back-up, just in case.

Bruce this is good info for me too. Based on newer FEDs I see around, I was assuming that 'modern' wheelie bars were all mono-wheel and two-wheel designs like mine were history. Wrong?

Ricardo I have seen plenty of guy's with double bars on there cars and they work pretty well .For me there is just no way that I would even think about taking my car down the track without some sort of bar on it . But that's just my opinion !

FED newby and know nothing about tuneup for car.I figure wheelie bar is cheap insurance and xxxx looks cool too.I look at it like carrying my 45 auto better to have and not need than to need and not have it.
retroboy:
This is the sort of thing I'm talking about. Sure cleans up the back end of the car.

I wouldn't do it. If you hit that roller and jacked one or both rear tires off the track there's no telling where the car's going, and I'd bet it wouldn't be straight. I'm with Bruce on the springy thing. Mine's 150" SBC, PG, 5.7, 125. I bent a couple of fronts from a hard landing, so there will be a wheelie bar on mine at all times.
Just my two cents...
Pic of the 5' bar I made, lower bar bows upward on hit. Tunable for spring with upper bar mounting location options at the wheel housing.
