Couldn't get the tires to from burning the drums!!! Does anyone have any tricks or whatever to keep the tires from smoking the dyno drums??
I'm trying to hit 150hp shot on the dyno and as soon as it hits, the car just roasts the tires and we can't get a good reading!
I heard of having a couple people sit in the back, but that seems kind of dangerous.

I'm guessing it is a small roller so the car should have 4 straps crossed in the back. 2 off the lower A-arms and 2 off the frame.Tighten them till it pulls the car straight down onto the roller.Also make sure the tires are on the forward part of the roller (going down hill towards the front).
Adding bodies is done a lot. Tighten straps, add bodies and if all fails, drop tire pressure a little. What kind of tires and what pressure are you running?

However, I think the next time I get it dyno'd it'll be on a dyno jet and the rollers are like the ones your talking about.
I'll write this stuff down and try to get the shop to follow them!

So there should be no reason a sudden introduction of 150 additional horse power will blow my tires away IF on the dyno the car is strapped down properly...........correct?

Many Mustang dynos, model MD-1750s, use large single 50" rollers as apposed to the dual roller Mustang model you described, much better traction. I'm assuming you have an auto, otherwise just use a higher gear for better traction.
