14-71 blower questions

I have a brad 5, 433 cid (converted my a/fuel setup) in top alcohol flatbottom drag boat and I'm looking for a 14/71 blower. I've talked to a lot of different mfgs about them and they all have the best. Right now I'm looking for a used set up and need suggestions. Like make, model, rotors k8 k9 or k11, should I set it back, injector, anything helps as I'm very new at this. Or should I just pony up and buy a brand new setup? If so what is my best bang for my buck? Is it worth going to DMPE or for boat racing should I just stay local with Littlefield. Thanks for any and all your advise?

Call Andy @ Littlefields
ask him about the new blower they have, I think they are available now
dont think you can go wrong with it for the price

 

If you're buying a used Kobelco, make sure you get one with K11 rotors, the K8's and K9's are prone to coming apart, based on my own personal experience.

A brand new littlefield is a very good blower, and it has the K11 rotors in it. It is a very good value for the price.

I have heard that the PSI is the best, but it is about twice the price of a littlefield.

 

the only way is Mert Littlefield...14-71 retro hihelix..mine puts out 50# at 50 over...very happy..no....veryyyyyyy happy..Dave Lowe

 

Thanks for the help, I'm pretty much set on the new littlefield. I just don't want to give anything up, do you guys suggest doing any mods to these or just run them as is? If so who? Also any suggestions on a injector? I'm not real fond of the B&U whats a good carbon setup? Thanks

 

Lb20

I agree for the money there great ,the LB20 is the latest avaliable it has an open pocket on top front of rotors . really you can use it right out of the box and be very happy for a little over $6000 if you need more than this plan on spending a lot of jack
