dcairns Posted December 17, 2002 Report Share Posted December 17, 2002 Using this calculator: http://www.prestage.com/carmath/calc_etmph.asp you can get a rough idea of what it will take. Stock: Weight 4142 Flywheel HP 285 Estimated Rear Wheel HP 228 Estimated ET 15.30 Add a Whipple supercharger, +45% HP : Estimated Rear Wheel HP 330 Estimated ET 13.53 Link to comment Share on other sites More sharing options...
RATFINK Posted December 18, 2002 Report Share Posted December 18, 2002 Average stock times for the 5.3 around here are 14.9-15.2 or so. A friend of mine has a 2000 5.3 which we installed 4:10 gears, auburn locker, whipple charger, water injection, and some HPP3 tuning. He also has exhaust but is still using the factory manifolds. His best time to date is 13.062 at 104.4 mph and was ran on factory tires with 10lbs of boost. RF Link to comment Share on other sites More sharing options...
PotbellyJoe Posted December 18, 2002 Report Share Posted December 18, 2002 dcairns, you need to add for the driver. not to be critical of the numbers, but ~200# makes a difference. Sounds like a nice truck to start with. I would have to say it would be the way i would go as oppose to the SS if I ever were to sell my sould and go over to Chevy. I hope things work out for you and you build a hell of a truck.... -Joe Link to comment Share on other sites More sharing options...
ssvette Posted December 18, 2002 Report Share Posted December 18, 2002 Or just a 125 shot of NOS will work, just to keep you guys up on our racing team the GTP with the 6 cyl just ran 13.57 at California speedway last Saturday, it too is supercharged.

dcairns Posted December 18, 2002 Report Share Posted December 18, 2002 Joe- You are right, I was in a hurry... I am supposed to be working here... I was mostly wanted to put up the resources for him so he could play with the numbers. Actually, I was suprised what at the difference the weight made between the SS and the reg cab Silverado on the projected ET. I better start working off a few pounds..

PotbellyJoe Posted December 19, 2002 Report Share Posted December 19, 2002 Its funny you say that about working-out. I had a convo the other day after my calc final with some of my car buddies at school. One was like all into those racing glass windows for his chevy and was like "they take off 15 pounds" or something to the like. I responded with something to the likes of, "its cheaper to go to the gym and lose the same amount of weight you moron." nothing like 6 guys rolling around laughing. -Joe Link to comment Share on other sites More sharing options...
