Is there any twinned Duramaxes in the house?

OK guys as much as I enjoy reading your comments to each other about your tunning and your Single Vs. Twins.. lets keep this thread civilized.

Thanks,

Phil
 
I thought you were a big shot tuner bobo? So I'd have two states to pull in if I had twins, OH & WI. I could also pull with DHRA Super Street but that class is dominated by big singles and they are allowing unlimited drivelines next year (rockwells, profab, ect) .

The original bash was against twins and track times. I know squat about pulling.

The twins work well at the track and the street. With twin CP3's I think I could pick-up the .3 to run with you Michael, but it's not in the buget right now. It is fun being one of the fastest max's in the country, but I mostly run bracket events, so being the fastest isn't a top priority.

With more people running twins now, I guess I'll not take offense from comments unless directed towards me personally.

I'm off to the track for a five day national pro event.

Good luck at the Halloween Classic Rob!! I really wanted to go this year, but I have other racing conflicts.

I understand there will be some other diesels racing in the sportsman class as well, as a couple of you in the Pro class.

Go get them!!!

A big shot tuner? I never said that, but thanks for the compliment!

The twins do have their advantages but for all out power I still think a big single will make the same or more power. You can produce more boost with twins but boost is just a measure of restriction, not power.



Yes and no. Will your Aurora make the same power as Bobo's? Yes it probably will. Will it make the same as Keith's set up? Not a chance in He!!. Keith's big turbo flows over 50% more than your Aurora.

Higher boost means your trying to shove more air into a given space over the same amount of time. It's not all that uncommon to be able to make close to the same boost with a single as twins if it isn't wastegated but making 50+psi with a single isn't where the hp is at. Your rotating a lot less weight with one turbo vs. two. The advantage to twins is really good street manners and low egt's yet the capabilities of high hp. As the every day hp levels go up that get's harder with a single. It's simple physics. As a rotating mass increases it's harder to turn with a fixed force. There are ways around that (like smaller housings and turbine wheels) but they all have consequences. There will come a time/hp/smoke when singles just wont cut if for anything less than a race/pulling truck due to drivability.
 
And now we all know why Nathan (Maximized Performance) is ......."The Man!" :woohoo:
 
Idaho CTD, I don't consider the Aurora a "BIG" single. A turbo bigger than the Aurora can still be streetable if it's built and sized right. With an auto trans and the right converter a "BIG" turbo can be very streetable.

Yeah you have to remove rotating mass to get it too spool (damn physics again) along with using a tight housing. You can run a sloppy converter and it will make boost/power way up in the rpm band to make it seem like it drives good. Sure you can street it but it's no where near ideal and you have to work at not barking it. It's comical what people now call streetable compared to a year or two ago.
 
:poke: come on keith that aint big compared to my next TURBO ..........now that is B I G >>>>>:kick:
