I don't know why this hasn't been posted yet!!! Insane MPH!!! My guess is fastest MPH with a truck still on leaf springs??? That's some insane mph!

He left on 5 psi, ramped up to 18 psi in first gear and then a total of 25 in second.

SPT Winter Blowout 2013 Second Fastest truck Flaco in Lil Sis Running 9.1 @ 175 - YouTube

 

That mph is insanely fast! I can only imagine how hard it pulls

 

50mph out the back door? Crazy. Some twin turbo pro mods don't do that lol

That mph is good for 7s.

 

Wow. That's insane. Where is falco now?

 

Was that done twice?? 50mph out the back is ******* wild!

 

Just what I was thinking! That's crazy!!!!!!!

 

making right hand turns at 175 seems a bit dangerous

 

25psi plus 427 cubic inches? I guess that's how you gain 50mph out the back lol, but yeah I agree, that's insane! Unless his truck weighs alot less than a stock RCSB he's making 1800+HP!

 

Lmao, I was waitin for someone to mention that

 

thanks guys....those are the first shakedowns with new combination...434ci bigger cam, new glide and converter and a 106mm turbo with 5" down pipe..... need to intall the ams 1000 on it so i can really take advantage of the power down low..
