I was woundering if anyone can tell me how fast there truck goes with the similar upgrades to mine. I can only get 95 out og mine? i i think i should be able to go faster than that. my friends stock truck goes 90 with 4:10 gears I got aeverything in my sig done to it! what can i do to get it to go faster, i would be happy with 110 for now, but i dont want to sacrifice low end speed either.

 

Did you take into account for the dream-o-meter being off from the larger tires? Just throwing it out.... I got my ol 2000 up to 105 with 410s and 33's and dads 99 dually 355s with stock size got up to 115ish. Thats a whole lotta truck at that speed

 

yeah my 96 with stock springs with linkage took up a bit will hit 112

 

Hmm, well i havent tested it with the 35'' tires but i do know it was right on with 33'' tires i used my gps to test it! i'll try it tomorrow with the 35's see how fast im really going BTW, is it easy to change the speedo gear in the 47re if it wer to be off?

Well, i just took it for a boot, used my gps in my phone to check how fast i was going and it was within 1.6 mph, so i would say its just about dead nuts. Im guessing i have other issues. Once i get the 100plate i will see if that helps me out on the top end. if not see if i can trust myself to bump up the timming. its @ the 14 degree stock setting as far as i know. I guess the gsk kit is just not as good of an upgrade as i thought...

 

Yea with the extra rpm and 3:55 gears u should be easily in the 100's

 

I can reach 100 in my dually with 4:10's pretty easy. So I don't see any problem in you getting there. Maybe your under valved

 

with the probloms your having i would think your running out of fuelyou can buy a cheap psi guage and hook it up to your fuel filter and check it.

 

I CAN ONLY GE TABOUT 90 WITH MINE,BUT THATS IN THE RED.

 

I have hit 110 in mine but thats in the red thats with the calculation for my speedo being off by 15% due to tire size, I have 4.10 gears with the 35's. I was running pretty hot egts though so i wouldnt suggest doing it for a long time.

 

I can't get my truck to hit over 1000* unloaded, loaded it will go higher thoe but she goes 95
