Who makes the latest greatest twins and injectors?

You might also want to consider some billet shafts(input, intermediate, output) from DTT if you plan on drag racing, sled pulling, or being heavy-footed.



High Horsepower can break the stock shafts, but high HP plus big tires compound the stress.

I have the billet output shaft. At the time when I did the transmission the other shafts were not created.

IMO, there is no real magic combo. Pick a continuous power level, and tune for it.



Well here's my intention; As you can see from my profile I'm half way there. My next venture is of corse compound turbos and F7 injectors. I spoke to Poole and he was mentioning F1 springs for more valve closing pressure, I'm not sure what good that will do since combustion chamber pressure will surely keep them closed tightly, and more RPM I'm not sure about that either... . I know two things I want to use my KSB-1 and I want F7 injectors, since I have a DD cam in it now. I guess I want to tune for what ever power level compound turbos, F7 injectors, DD Cam shaft, and the DD ultimate fuel module (non defuel) on level 5x5 will produce.

I still need to talk to a few more suppliers, I would like to get my head O ringed and ported and polished and of corse new studs.

The springs keep the valves from floating under high boost. Cylinder pressure wont do it when the exhaust valve is open or the piston is on the down stroke. That combo will go over 600hp fairly easy with a B2 primary and your KSB1 secondary.

true words indeed--I have some pretty stout ones from Bully Dog that work and may be the stoutest ones out there---chris

So for all us twin curious followers, If we had a say DZ/B2 set built like AFARMER above how easily could the secondary be changed to a switzer varient or something bigger. Would the plumbing need serious refabed or just diffrent boots or what? Just fishing tha answer to how permanent a twin plumbing kit is or is it universal. Say you did a htb2/ht3b could you change the 3b to a B2 without reworking the plumbing?

When I upgrade to a SPS62 with the bigger turbine housing and wheel won't that make a good secondary?
