V-10 Drag Pak Challenger help

Radials like a lot of air......and on a fairly heavy car with a lot of power you're probably way to low on air....

10" wide rims and around 18-20 lbs is what I used on a 10 second LT-1 Firebird.....60's as quick as 1.34.

I went to a ten inch rim and radials. Dropped my sixty foot down about .03 and I run about 22 pounds in a 72 Gran Sport.

Yep, in Stock you cant run 10 inchers, but if you are bracketing, with the right offset on the wheels, you "should" be able to get them under your Challey. And then you can work on tire pressure that is best for you.

But no matter what you do, don't expect expect really stellar 60 foot times. These V12 cars simply don't launch like their little brothers, the 5.7, and 6.1. Our 5.7 regularly runs 128 60s. Most 6.4s are still sorting out their 60 foot too.

It is all about managing the torque. And that is a real balancing act. But with a two speed tranny, which never made any sense to me, you either give it up in the 60, or later.

What did you do with the rear wheel package that came on the car ?
The radials like 18 to 21 psi. Have you scaled the car with you in it ?
