I was just wondering what are some big singles people have run on a First gen. And what are there results. I have been starting to turbo shop, and just wanted to hear what people have tried. thanks!!!!!!!!!!!!!

 

Well, I know bgilbert has a SP66 from HTT, but I havent heard any numbers yet... He should pop in here soon. I havent heard of many people running a B1 series turbo on the 1st gens, but I'm not sure why.

 

Because most people will tell you that a ve pump cant put out enough fuel to spool a larger single, but we all know that is false.

Stomp I know you love your twins, but what is the largest single you would think about running without a kta head?Rock on "1st gen's have some fuel"

 

Well I ran my HX40/16 as a single and it worked just fine. I put down 419hp. It would still get hot though. I think you could get a way with a sledpuller66 with a smaller exhaust housing to help with spoolup. Or a phat shaft 64 or 66. A B1 would also do fine. Pump would have to be maxed though. The biggest thing is there is going to be some lag no matter what.

Heck after I broke my pump we put on a totally stock pump and it made it home. It was a pig turbo's didnt even try to light 850* max. With my old stocker maxed out I could get to 1100* and sometimes 1200* with the twins.

I wouldn't be afraid to put any of the big singles available on a 1st gen with 12mm pump. Just depends on what you consider lag, what your intended use of the truck is etc. A HX40 is good til about 400rwhp, then egt's get hot. If you are wanting more hp for sled pulling, I'd pass on the hx40 and go with a B1 or the like. B1's, HTB2's etc are based on a Schwitzer s300. Tougher than the hx40.

 

Yeah, I am not afraid of some lag, because when it lights watch out. I was Thinking about JR's Baby 55. Would that be too much?

 

This would be with the usually pump mods. Gov spring. Ground Pin and afc lever. Or do you all think I am crazy!!!!!!!!!!!!!!!

 

Wanna try a full bore B1?? I've got one available, if you want to try it!

PM me, I'm too close for you not to
