This may be a dumb question but what is the max speed the truck will run on a 2003 HO 48RE?

 

im pretty sure stock is 112 mph

 

With the speed limiter still enabled...IIRC its closer to 104mph....I have had mine up to approx 130mph...2 needles past 120mph. 3500rpms...!

 

not a 03, but had mine to 138 on my gps with 35s, an intake, exhaust, and BD with cl tune

I agree with DENVER DODGE, it should be about 112-113 MPH if you have the higher gear ratio (3.73). With the 4.10's it is going to be lower.

I'm no wimp guys. I've done over 180 in a couple of cars in my life time...but shakin down the road at 130+ is KRAZAY!!!

 

125 in my 03 so 5spd drw

 

do you have a gearvenders od or 40 inch tires or something????
i am at 3600 in 6th gear at like 110 and thats with 36s

 

3:73 stock tires . with your oversize tires your speedo is off plus if you have 4:10' my 06 and 07 is like that withe g56 which is like having 4:10's

 

i have 3.73s and my need set of tires are going to be 38s or 40s to drop down my cruiseing rpm i will see if my mileage goes up again because it did when i went from 33s to 36s

 

127mph GPS verified on my 03. At the time I had 4.5" lift, 35" Toyo's, orignal 130hp Smarty program. This was back in the day before the smarty could adjust top speed. I just used the key start trick top reach high speeds. At 100mph turn your key and hold it in the start position and you will be able to go as fast as you can.

Now that I have more mods I know I could hit 130+ gps

Here's the video.

Hmmm well I hit 120 when the air hose to the intake slipped off

 

I am pretty sure you are going to drop MPGs. You are going to put more wear and tear on you tranny and your egts will be generally higher because of the extra load. Speaking from Experience.

I have driven many times at 165-172 range, mustang and Street Bike, and I will have to agree to the above post that 130 in my truck is a puckering experience. One that I will not go and try just for fun! On another note, my last dyno runs at Edge in OD showed me at 160mph. I thought my tires were going to grenade!

 

The reason I asked is that the Smarty SR has the speed limiter but Jr does not. Trying to justify the SR as I would like to try the JR. Only need the power of the JR as the SR only goes to 130 hp for the 03 trucks.

 

My Stock 03 will run up to 108 mph.
