What happened w/ the Radix Supercharged Run?


m396 #00-011

Recommended Posts

Wish I could have gone to see it. I didn't get home from work early enough. How many runs did they get Thursday? Also in addition to the sc did they have anything else done to the truck? By chance do you know what time they ran when they did their stock run when they first started their testing?

Here is a prevue of some the test results to support our

upcoming install article on the Radix.

Take this data as preliminary:

 

Stock (tailgate down):

 

60' 2.335 sec

330' 6.614 sec

1/8 10.169 sec / 70.13 MPH

1000' 13.234 sec

1/4 15.875 sec / 85.05 MPH

 

max HP (2nd gear) - 250 HP

max TQ (2nd gear) - 271 HP

 

With Radix (tailgate down):

 

60' 2.001 sec

330' 5.771 sec

1/8 8.904 sec / 79.12 MPH

1000' 11.642 sec

1/4 13.990 sec / 95.81 MPH

 

We made about 10 runs around 3PM. Best time was 13.99 (above).

The rest of the runs were from 14.001 to 14.05.

We left for a while and came back for test and tune that evening.

 

We made two more runs (best was 13.98 other was about 14.02).

This was with no tailgate and no spare. The truck sat for about

1.5 hours before our first run of the evening. I really think the

fluids were too cold and the drivetrain needed heated up.

 

max HP (2nd gear) - 340 HP

max TQ (2nd gear) - 345 HP

 

timing advance - 15.5 degrees

0 knock retard

Ltrims at medium cruise - 3%

 

We measured the aerodynamic drag and rolling friction.

Based on our calcualtions and measurements, the top speed

is about 149 MPH drag limited in 4th gear.
