Alright I was talking to the shop that I ordered the KB through.(local) and he told me that he ordered the KB for 14 lbs. The KB rep told him that no boost a pump was needed or 55 injectors.
Know the rep I guess thinks this is going on a stock crank pulley truck. So the question is what upper pulley will this KB come with and I quess I will be running a stock lower until I get dual pumps.

Please let me know what size upper it will come with it, if it is going to be 14 out of the box.

I am kind of upset that my dealer told him I had a stock L.

 

I ordered mine with a 3 inch upper, but mine can with a 3.5 inch upper.

I will bet you 10 bucks yours will have a 3.5 upper too.

 

Mine was ordered with a 3.0, and came with a 3.0

Guess it all depends on who your order it threw; probably when you try to get them in the back door like JDM the pulley sizes get screwed up

James at Runnin' with the Devil sure got mine to me correct and very fast

 

I ordered mine direct from Kennie Bell

 

mine is direct from kenne bell. So you are saying the kb with a 3.5 will show 14lbs? or it will show 14 with a 3. KB said they are sending me a blower for 14 lbs,w/ stock lower. Does this sound right?

 

With a 3", mine shows 14lbs using a stock lower.

 

I ordered mine with a 3.5, 3.2, & 3. With an 8lb lower and the 3.5 I see 14, 3.2 I see 16-17, 3 I see 20+. Of course that depends on the weather. In cooler weather you're going to have more boost.

 

What octance fuel do you have to use at 14psi?

 

I use 93 octane up to 18#.

 

The fuel depends on the tune not the boost.

 

Ok, thanks. I'm interested in a KB but all their info and dyno's were done with 100 octane fuel which made me wonder.. I don't own a L yet, but I plan to very soon. Here I am talking about aftermarket blowers already haha..
