I think I hit the limit. At 138 it shifted into 4th and didn't have enough left to pull any faster. Flatlined at 138 mph. On a positive note, my IAT's are a hell of a lot better than my last post. Last was 132 mph at 196* IAT. The meth really helps out a lot.

 

Time for a bigger intercooler and smaller pulley and the 6L

 

what size nozzle you running your meth thru...

 

Not sure, whatever came with the kit

 

Where do you performe your tests at? Open highways are something?
138mph aint bad! maybe a small shot of NOS will help you go faster.

 

cool,

i've logged a 2000 single cab 2wd truck with hardly any mods that went 135, driveshaft went boom also.. i count my lucky stars on that one.

 

i have never had a log with iat's like that. thats crazy of course i'm not blown

 

what gear ratio are you runnin?

 

Radix = BBQ, as far as IAT's go.

Gears are 3.73

I never really thought about the drive shaft...what are they rated to? Maybe I shouldn't do that again.

 

If you have the aluminum one I would be careful. You should have a two piece steel thought right? Well I dunno with 4x4.
