Post your thoughts here. How much time do you predict will be reduced with each of the following mods and how much combined?

1) 220# weight loss (tailgate, spare, jack, sub)
2) 140# wheel/tire weight loss (Aluminum wheels/slicks and skinnies)
3) 0.4 second reduction in 60 ft.
4) 225 to 250 additional flywheel horsepower (exhaust, intake, N20 or supercharger)

My guess
1) 0.2 seconds
2) 0.2 seconds
3) 0.7 seconds
4) 1.0 seconds
Combined 2.0 seconds

Agree? Dissagree? Discussion?

Pretty sure he means a 225hp shot of juice. (Nitrous Oxide ;) ) :cool:


If everything goes as planned (traction, not missing a gear, clutch slip etc), my guess would be at least 11's.

At any rate, it definitely sounds like a fun plan!

Most of it. I figured a little extra for exhaust, intake, and engine management (VEC-2 or AEM unit) mods. Could be 250.

Trev17, I cleaned up the original message a little. May be more clear now.

Hay steve, Are you going to have any tires when you try it with the juice?
We tried some 18" on mine and they clear the brakes,but the only
tire to fit so far (for traction) are the Nitto drag radials. Mofo

phoenix......makes a 16inch drag slick....i know that the 16inch wheel wont fit but if you put on rotors from a 2001 dodge truck then the 16 inch wheels will fit............2001 dodge rams have 16 inch wheels the rotors shouldnt cost that much .....i might be doing this to my truck so i can spray off the line and lay the meat to the ground at the track

If you can get the rotors and calipers off a 2001 Ram to fit then 15" slicks and rims would be the way to go. I've been thinking of switching to 18" rims all the way around but I want something wider then the standard 8" everybody seems to make. The L gets the 18x9.5 which is what I'm really looking for but I can't find a nice priced low weight version (like the centerlines) in a 5x5.5" pattern. If the L owners really are trying to be helpful as they claim, then find out waht the older Ford guys with the 5x5.5 pattern use for wide 18" rims. My guess is they probably just use the 15's and 16's instead of 18's.

I will soon have some slicks, 16", but will need to make some brake mods. To change the brake caliper mounting bracket on the SRT-10, you have to pull the axles out. I'm hoping an adapter that uses the factory caliper mounting position will allow a 13" rotor and smaller caliper to be mounted.

Unfortunitly for everyone, you guessed right. All the Ls w/slicks are running 16in rims in back or grinding the rear calipers to fit 15in rims. either one opens up a world of choice.
for 18s it's pretty much the 305x45-18 Nitto drag radials :(

The weight savings will be a great addition! As for everything else, it's hard to say, but looking forward to seeing your results! :D

traction is going to the problem.

Even if you have a slick on the rear, the rear axle will twist and could result in the driveshaft binding. that is why most tracks have a rule if you run slicks you need to have traction bars.

once you get up to speed (1/2 doen track) areodnamics is the biggest factor. Lets face it we truck drivers are driving a brick wall aerodynamically down the track.
(fold in side mirror)(try it with tonneau cover on and off)(try it with tailgate up and down) figure out what works best.

I'm not sure if you will pick up 2 seconds. again aerodynamics kill trucks.
You will definitely pick up a second. most likely 1.5 seconds.

I know the srt has a factory type traction bar, but the rear end will still twist a little. (known as axle wrap) I think that would be my main concern about running low 12's.

also some tracks require a roll cage if you run faster than 11.99 others are 11.49.

keep us posted

What was the stock baseline - 13.4 @ 106?

With your mods, a 2.0 short time and a clutch that will hold the torque, you should be a low 12 maybe a high 11 at 115-118 mph would be my guess. Good luck with it!

Doesn't the srt-10 come with traction bars built right in? Thought I saw them when I was drooling over one at my local autoshow.

9 seconds........dont forget about the grill mod its worth a few mph in the 1/4 mile and very easy to do.....its only a track trick but it works ....i made mine out of clear lexan plastic 4 pieces and installed then on the inside of the grill when the hood is closed no one can see them .....they help with the aerodynamics....the air will go around the truck instead of in the hood and under the truck......this mod helped my 03 slt hemi longbed run 99mph in the 1/4 mile... how many other hemi trucks run that without juice or headers

thats just one of the mods that helped me run 13.71 at 99mph

well worth doing

Wouldn't you get the same results by inserting some of those grill covers you can by at the aftermarket places?
