How do twins work?

[pwerwagn]

About why gas motors are twinned, I think that is due to space. With most being a "V" configuration, it is sometimes easier to just run two chargers and not worry about getting the exhaust from both sides to one charger. We ran a single T-3 on a 1. 8L straight-four miata motor and made 32 psi with it intercooled. should have been around 500hp. (worlds fastest miata powered miata!)

However, I am going to do twins on my 360 dodge, just because it seems like it will be easier to plumb everything.



and most people want a "Twin Turbo" sticker!! J/K

Im still a lil about why the twin set ups are piped like they are...



I had it pictured in my mind that the Small turbo would pull the intake air in, charge it then use that charged air to help spool the big turbo, then it would get rammed in to the motor. But you guys are the professionals.





Anyways... What kind a fuel volume warrents the use of twins?



Say a guy that had a set of 370's/191s and a mean plate wanted to burry his foot in it without to much concern of exceeding damaging temps on the Ol'pyro b4 he got back up to hwy speeds (80mph) and just wanted a lil bragging rights about twins Oo. ... . Or is this to small of an amount of fuel.

our engines don't flow a lot of CFM... the reason we have turbos in the first place is to add OXYGEN... if you can't increase the CFM, you must increase the DENSITY... IE, you gotta pressurize (boost) the air to pack more oxygen into a given space.



the big turbo flows more CFM than the little turbo... so it takes a big ol' gulp of air, and compresses it a little into a smaller package and feeds it to the little turbo... then the little turbo takes THAT and compresses it furthur into a nice little package that the engine can accept...



370's, 191's, and a mean ol' plate will need twins if you wanna lay into it w/ abandon.



'course, I bury my foot up to 80 w/ no concerns... I just can't stay in it much longer! LOL!



you can size twins as low as 400hp with a little HY on top or 600-700++ w/ an HX40 or B1 on top... and anywhere inbetween.



back on turbomustangs.com, we always called turbos "hooters"... because two is better than one, and some of the bigger ones are really fun to play with
