Don't forget it's a diesel he's talking about.

"2002 24v 2500 cummins 5 spd"

 

Ah, good point. Well, that DOES make it easier..... Jig should chime in here.

 

then build a 500hp truck with cheap tires... oversized sticky tires are not going to loose traction where cheap tires will on dry pavement. its why I chose my tires...I would rather hook up and go than sit there spinning while the vehicle I'm trying to pass passes me because I can't get traction.

tires really do play a huge part in this. bfg mud terrains are not going to break loose easily on dry pavement even with 1000hp. they are a sticky tire and have excellent traction. now a cheap stock tire or tire rated to last 80k miles + is going to light up easily because its a hard tire with poor traction.

and ya still didn't read it all..

40mph roll I have lit up the mud tires. you gotta power brake it to get it started though...once its started it'll stay goin. and never do it in final drive gear...you WILL break the gear trying to do it in overdrive...

I broke 5th and 6th gears in my NV5600 (6-spd manual) just by putting the skinny to the floor up a 6% grade with no weight in the truck at all from a 1500rpm start already in gear and cruising... turbo boost pegged 65psi in about a second and truck was pullin hard and boom...gears gone and free revvin...try to go into 5th, its gone too...finally ground it into 4th (synchros went with the other two gears) and got it home limping with nasty grinding noises the whole time...

 

and here is the carnage...

 

@ Jigabop

I am curious, at retail prices just how much $$ is in that truck for motor upgrades.

 

mine?

too much... LOL

lets see...

brand new retail...

$800 fueling box with monitor
$65 fuel pressure gauge
$100 dual boost gauges
$100 custom made pillar mount for gauges
$30 steering column gauge mount
$1400 Dual disc clutch kit + upgraded clutch hydraulics
$1200 S357 turbo
$700 S475 turbo
$1200 twin turbo plumbing kit
$300 5" exhaust + 5" downpipe
$400 ARP #425 head studs
$180 upgraded intercooler boot kit with spring clamps
$600 7x.010 injectors
$600 150GPH fuel system with 1/2" fuel lines
$300 modified liberty fuel module
$~200 powder coat for twin plumbing and various other engine parts


that should cover go fast parts and supporting mods I have so far...doesn't count steering upgrades or in dash nav or sub and amps, etc...

nor does it count repairs along the way to get it to that point..(2 blown turbos, blown head gasket, etc..)

yes over $8k into motor mods and supporting mods alone.

the older cummins trucks are not the cheapest to break 500hp with. but once you get all of the supporting mods there, they are reliable daily drivers at those power levels that will tow anything...

same hp level can be built for cheaper but if you have ever rode in a 500hp single turbo truck and a 500hp compound twin turbo truck you will notice a huge difference of how they drive and handle on the road...the 500hp single turbo is gutless until it gets toward the end of its RPM range and the turbo finally spools and launches it hard... the compound twin trucks power comes in far sooner making its power actually useable for more than just competition.

also a note...I didn't pay full price for everything...I got my injectors used, got head studs, twin kit, and turbos at a discounted price, got clutch at a discounted price, etc...so I have a bit less than full retail, but it gives you a ballpark idea.

 

I'm going to have to call BS on the 750 whp Vette running 8.90's. Rolling burnouts in it should be easy though. My car with around 500 whp smokes tires easily under 60 or 70.

 

I was thnking of throwing the BS flag from the first post....

 

Sorry, I guess I didn't shear off splines in a trans, or **** my pants, I forgot you were there with us. Here's a better question, if you already knew the answers why did you ask?

 

Rolling burnouts on a freeway is NOT what hot rods are all about! Some of us may be old enough to remember when Hot Rodding was alll the rage. It was not about doing things on crowded highways. More for track and streets less traveled (usually at the outskirts of town) where no one was likely to get hurt (or caught by Johnny Law).


And instead of telling us what NOT to tell you, why don't you educate us about how this isn't dumb by providing intelligent reasoning, and telling us it's worth, in your opinion?


Probably a good idea
