Pull Bars: Then vs Now & Open Vs Crate Tech

[mod71m]

The one thing I can tell you about a solid pull bar, is if you are on a rough, locked down track, you will hate it. Smooth is a different story though.

It's interesting that you say that. I run a 1450 spring or a 1000 to 1600 with with 3/4" preload all the time and i've not noticed it's a lot better in the rough compared to less preload or a 1050 spring. On the cushion I've always liked stiff, stiff, stiff! That's part of what made me want to try solid.

I can see why you say solid may not be the best in the rough since the spring will absorb some of the shock when the tires are jumping on and off the track. I'll give it a shot though and see what happens. Typically I'm pretty fast in the rough just due to the driving approach I take with rough tracks. We shall see.

Thanks for the feedback!

Also I've seen many nights when the fastest Sport Mod was turning equal to or faster lap times than the fastest Modified. He was doing that on a 2 link and solid pull bar and always when it's slick, granted the 5" spoiler was helping out.

That guy races Modified now so it doesn't happen as often any more, however the fact still remains that the fastest car on the track on many slick race tracks had a solid bar in it...

And a 5" blade, and less torque.

The few times I got to run a solid bar,I liked it, WHEN the track was smooth.

With less hp and a smother power curve the sport mods can run the same times as an A mod. We've seen super/pro stocks doing it with 600 lbs more weight and only 3 link suspension. I know working around the IMCA territory the tire can only provide so much grip. Example: if a car was running say 4.7 seconds down the back stretch and 5.6 in the corner and the next lap 4.6 down back stretch the corner speed was usually a tenth slower timing drivers in sections. We've found the crate motors aren't needing as much cushioning as an open motor because the motor is less prone to over power the racing surface and is easier to control the throttle. But we have tried solid on tacky because the grip is there but dry slick were finding we still do need that small amount of energy absorption. Less with the crate motor and more with an open motor running 500 + hp.
