For the guys on here that have dynoed there trucks and even some quarter mile times. Also what other mods go along with it? Just trying to get some estimates for my build.
 
There are a couple of people that have recently put on 13mm pumps. I just drove mine home after having mine installed. Might have to wait for the weather to warm up before people can report their progress. They are different. I saw that before I made it to the first stoplight. I thought i made a good choice for my new primary. This pump spools it like towing twins. Throttle response takes a few miles to get used to also. Not really touchy, just very reactive.
 
What kinda turbos? I am having a hard time deciding since I too wana still cruise on the streets with it.
 
Ron, I'm installing an S480 under my SB 66. Do you think this combo will spool well considering the fueling of the pump??? It should be interesting. I'm also installing a new converter with 1600 stall.
 
I'll be interested to hear how that works out, Tim. I got a feeling it may work out surprisingly well.

I can't wait to dyno with the new pump. I'm tempted to dyno before the twins go on just to see.
 
I'm just trying to get mine up and running again with the 64/71 as a single for now. If the weather holds, it'll be this weekend. I miss my truck.
 
What size injector lines are yall going with for a 13mm pump? Does it need more fuel to keep it alive? How's the idle?

I've run S480 a couple of times. Most recently with my 64/71/16 on top. It isn't bad if the fuel is there. I think the 13mm pump would help quite a bit. I have never run a 66mm top charger, or any of the Silver series. I have been told they are more lethargic. Again, I think the bigger pump is going to help. On a side note, the haze from my Mach 7's is worse with the 13mm pump than with the 12(no surprise there). It goes away out on the road. It is nothing near as bad as the haze from my 6 x .016's with the 12mm pump. But the bottom end response and smoke is better with the 7's and larger pump, than the 6 x .016's and the 12mm. Just random observations by a novice tuner.

I'm using .093 lines and tubes, and from what I've read, you need larger lines to feed the pump for longevity. My idle is good, all I have to do is get rid of the extreme haze.
 
Its sounds like its not bad running it on the street, I wanted a 64 over something like an ht3b, I haven't decided yet.

Also I wanted to make sure it was flowing good so it doesn't burn up. I was thinking use my full cuts that I already have in my other pump, .090 dv holders, .093 lines and dual feed injectors.

Ron, a novice tuner? Come on, you've had more setups than everyone on here combined! Can you control bottom end smoke with the 64? How do the 13 mm pumps hold up street driving them?
 
Mine is going on the dyno friday. I should have graphs and comparison numbers between 12mm and 13 with same injectors.(not same day, but same dyno) I'll post them if it's anything interesting.
