The only thing I dont like about the truck classes is the restrictions you can do to the body (I like to mess with things). They dont even allow a chop top but he extra cab may even help with aerodynamics.

On another note there are at TON of open records in the truck classes and many opportunities to get in the 2 club.

Personally I would like to see more trucks.

GOod luck.

Thanks! I jumped the gun in asking anyway. I just did a little digging and found the answer. Just a little lazy I guess. Carry on!

The GMC grille is a little bit more AERO---but that truck is as aero as any GM has built---You will love the extra room that the EX cab brings to the table!!!!!!!

Run the truck and see if you are still accelerating in the timed mile.  If not the weight isn't hurting you.  If you are then better go on a diet,

The ideal situation would be to run through the timed mile at the highest possible speed for the whole mile.  In reality really fast cars/bikes are still accelerating at the end of the timed mile (either track) while slow cars/bikes have maybe obtained top speed before the timed mile.

If you are still accelerating then you want to try and increase the acceleration rate by either lowering the weight if you still have traction or if you can't use your lower gears because of wheel spin you might go faster by adding weight.  There is no "do this" and it will work for everyone.  We've learned a lot by data logging the TPS (throttle postion sensor) on Hooley's stude and rpm.  When we see that we can only use 25% to 30% in first gears we need to try and work on that area of the run.  Now in 2006 when we set a record we could see that at the end of the 5 mile we were not accelerating any more, but we did accelerate during the 5th mile.  Our speed would have been higher if we would have entered the 5th mile at our exit speed.  This year with even more HP we were accelerating a lot more in the 5th mile and also at the end. So for a real change we have to work on the acceleration at the other end of the track so that we are running faster at the 2 1/4.  In our case we hope another 500-800 lbs. will help us on both ends of the course.

c ya,

Sum, I am in the process of collecting old wheel weights to melt down and install about 500 - 600 lbs more weight, the final weight will be around 5100 lbs..

A tid bit of infomation on lead--- Speedway sells 50lb bricks for around $80.00 ea
The shipping was'nt bad either. We ordered 10 bricks last sept and they shipped each brick UPS in it's own package. UPS guy was'nt happy, he asked " whats in these boxes, lead?" We just laughed.
