Wheel speed

2600 LB Door car with roots , brad and a clutch.
What is good wheel speed @ 1/4 in.
Thanks Bruce

 

1000 .

 

Bruce at a .250?
Mine has 1700-2000 @ .250
.500 between 2800-3200
1.0 is between 3700-4200 depending on track now Cayuga and grand bend are on the low side of those numbers. What's the problem your having?

 

@250 in our wheel speed is around 1200. I am shaking @1.6 and I think it might be weak shake. That's when we put fuel back in and take out 5 degrees.

 

Bruce,

1200 @ .250 seems pretty low. Weak shake sounds dead on to me. Youll drive into shake at the spot you mentioned or possibly even sooner.

1650-1900 seems more on par, depending on gear, track conditions, etc... But thats a good reference to start with in IMO.

Also, pay attention to what it is @ .100. I look for 950-1150 depending on conditions.

 

I don't understand how anybody can say weather that is or isn't enough driveshaft speed with the information given ?
Rear gear and transmission low gear will effect driveshaft speed .

 

198 low 1.41 & 1.41 with a 4.56 rear , 34.5 rear. Any ideas.
Thanks Bruce

 

I'm not a promod guy but... A 9.06 final low seems like a lot of gear to me ?

 

I had an idea about what Bruce had for power. That's how you can make a suggestion without knowing exact details. He's got quality stuff and runs well. Not too hard to give a rough idea on where to be.
