I ran a Gibbs RCSB Silverado last night, on the freeway once from about 80-110 (not too sure after 100), on surface streets once from about 45-80, beat him both times by a couple lengths. What do they run 1/4?

 

They are in the mid 14's from the tests I have read. They have lower boost then a regular Radix. I believe the Gibbs trucks make 5psi.

 

Hmmm that's where I am too when I take out my speaker boxes, tailgate, spare, tools, and have 1/4 tank. I was full last night...maybe he wasn't on it all the way.

 

Mjhoward has a radixed rcsb 5 speed 4.8 I beat him in the 1/8th but he was having traction problems and tuning problems. I think on the highway he would take me with the nitrous on IMO. He got the radix after he bought the truck and he is also pushing 11.5#s of boost too it is very strong up top.

 

I have run 2 of them here, they were running low 13's in the 1/4....the one guy just had a CAI and electric fan for mods.....and he was runing 13.2 all night long...

 

Isn't there like 3 different levels you can buy? I'm pretty sure there is.

 

Yep, all of them are not supercharged. Depends on what package you buy.

 

I guess I was probably not racing a supercharged one. He definitely did not have a chance of keeping up, and I only run mid-14's

 

that makes alot more sense. I had been hearing that the supercharged excabs were in the low 14s.

 

Mjhowards truck is a highway killer his third gear is really strong IMO it wasnt a s/c truck or he just couldnt drive.
