Where is the cheapest place to buy a set of BD Twins, and what is the largest size injector that I can run with them and still be able to two heavy?

Why don't you buy the almost new pair Cin's Dodge has for sale in the classifieds and save a pocket load of money?

I'd rather have the BD's I have been told they push more air and I dont think that the PDR set will work with my on board air compressor set up

ratsun

I guess your right, that PDR set will only comfortably support 550-600hp.
As far as your on board air goes what wont it support that the BD set will?

Who said that BD's push more air than PDR's?

blackdiesel

thats what im wondering....

ratsun

I'm thinnin it was a BD sales rep?

Mike Holmen

I thought that BD has only twins rated till 550 rwhp? I've seen a couple guys running drugs and getting over 600rwhp. PDR has put together twins rated to 1000rwhp. I'm not saying one better than the other. BD as far as I know only has a towing set available. I've never seen specs on a BD twins but I've heard good things about them. For most people the BD set will be enough. I also think that they are cheaper than the PDR stuff. PDR told me that they are working on a more modern twin set-up. It would be nice to know the differences in performance of one vs the other. BD wont lend me a set to try out for a weekend.

I see them on E-Bay for just under $3800.

I believe the BD's will support up to 600hp but I really wouldn't wanna push them much farther. Tiger Rag is running I believe it's mach 6's with his BD twins. As far as pushing more air than the PDR set I guess it depends on the which PDR set. The PDR racing twins will probably flow more but comparing the towing twins I'm not quite sure.

I was comparing the BD twins to PDR's towing twin setup and yes i do think that they will push more air. I have a York 210 air compressor mounted over my alternator that I have to work around. I really want twins but I'm not willing to give up my onboard air. There was an RV store sellilng them for 2800.00 but they don't list any BD products on their website anymore.

Your air compressor is on top of your alternator? The PDR twins will work. The only space issue you will have is by your right battery. I still don't believe that BD twins push more air than the PDR 35/3B combo. I've seen guys run the PDR set-up to 700ish hp, running only #2. The most I've seen with BD is the low 600's. Thats not saying that they are not good set-up. How much power you planning on running anyways? If your looking to upgrade down the road, the PDR set-up will allow you to change the bottom turbo housing from a 23cm to a 26cm housing. I would just buy the 26cm house 3B turbo. Its a bit lagger but you can run the mach 6's.

ratsun

I would have to agree, I have personally seen 687hp on the PDR tow twins on #2 only. My set came with the 26cm 3B

If I go with the PDR twins do I have to loose my second battery? Also how much will I be able to tow with and still keep it cool wth some m6's.

ratsun

No, PDR twins allow you keep the second battery
Mike will be able to answer this better for you because he had Mach 6s with his, but I think he had PDR street twins? I'm pretty sure he runs a hx40 on top? I would have a hard time believing you could tow with Mach 6s and a BD set
