Hey y'all need some advice , so I got a 1999 f250 fummins and right now I'm running 7x.010 sac style injectors and a BW 62-65-12 turbo plus all the other supporting mods and on the dyno that put me barely over 500 .... My question is what would be a good injector/turbo combo to get me in the mid 600 range , I would like to stay single charger .... Thanks in advance

 

I've been looking at a similar set up. A 64 should get you over 600 ish, may be hot depending what all you have. I'm trying to break 600 with a 64/71/14 bs special on 5x14's, 191, and supporting mods. And also may cam it which I think would forsure push it past 600. The 64/71 seems like it may be a bit small to push much more than 600-650 on a 12 valve. I personally am looking into a 467.7 as a single on a steed speed t4, 5x14's, 188/220 cam, hybrid dv's, and probably gonna go with around 20-22 degrees. Hope for around 600 but that's on a 175 horse pump and not the 180 that's in my buddies. I'm hoping it will give me room to grow when I get pump work. And they appear to have a rep for spooling as fast as 66/74's like the silver bullet, and often people say they are faster. A 66 would get you 600 or more. And has been done plenty. theres many choices. Even a 464 or 465 or even the 466 if you wanna go s400.

 

Wpg6.5 is on point here.

 

I'm running a 68 and 5x.14s and im just over 600 actually 620 to the wheels with all the supporting mods also

 

an s468? how does it spool? what housing are you running. i was interested in a 467.7 but wasn't sure i could spool it

 

a 64mm comp wheel turbo with either the 68 or 71 turbine would be my choice
