Another trip to the track in the 4.3

Recommended Posts

Took my truck up again to the track. This time have a CAI and running e85. Still have the computer cutting back my throttle to as low as 70% during the run but still ran good. Was great weather 57 and no wind. 4wd launch to 2wd manual shifting it. Stock tune pass was back in April 46 out with 93 Octane ran it the same way 4wd launch to 2wd left in drive. Next step getting a pass with 100% throttle the whole pass! Come on 14.99 :)

 

 

Stock tune Tuned

on 93 on e85

 

60ft. 2.28 2.21

1/8 et 10.33 9.84
1/8mph 66.8 70.5

1/4 et 16.19 15.39
1/4mph 84.1 88.8

 

Still not bad for a 5500lbs 4x4 truck with a V6 in it. :)

3.42 gears and 265/70/17R for tires btw.

Nice. I have to wonder, if the new 4.3 has been turboed/blown yet in a truck. Thats got to be Syclone/Typhoon all over again.

I talked to ProCharger and they said the 5.3 kit would fit on the 4.3 would just need a throttle body adaptor for the smaller throttle body and they said you would have to get your own tune for it. They were more then willing for me to buy the kit and they said they wanted to know how it worked out and blah blah blah. I know I'd love to try it but 5500 is more then I have to put into a new truck lol.
