Re:Running turbos in paralell...
I always thought the main idea behind twin turbos is that they're sequential in many cases meaning that one will work for low to mid rpm and one for higher.
I'm sure someone could give a more technical explanation or verify the validity of this - I'd love to hear it since I've got the same question.

Re:Running turbos in paralell...
you're right about twin turbos that are in paralell. one is for low/mid and other only boosts when you're in high rpm.
also reduces lag.
on the other hand if you twin turbo lets say a bb chevy, with a turbo on the end of each manifold. you could add the sum of the two pressures. since they're independant.
i'm seriously thinking of ditching my crx turbo project and twin turbo charging my chevelle. it has a 396 and i probably could run easily 15psi without retarding timing at all. and make like 600hp. and run 10s, with monster slicks of course. it would be more fun than my crx i think. i dunno though. its fun to have a fast daily driver. but when its a sleeper you have to prove yourself to every single ricer that wants to race... gets old after a while.

I would love to see some v8 turbo setups.

Re:Running turbos in paralell...
jeff i thinkin about twin turbo charging my chevelle and making it into a super-street dragster. it would be pretty sweet. not very hard either. just new jets in the carb and piping.
but the roll rage/slicks/ext would get expensive fast

Re:Running turbos in paralell...
you have to buy or make something to connect the charge pipes to the top of the carb.
you can run quite a bit of boost on a big block chevy without retarding the timing. or even cooling the charge.
the jets only put as much gas as related to how much air is coming through. if more air is coming in more fuel will travel through the jets. you can also just have big jets in the secondaries (only used when it boost most likely) and keep regular jets in the primaries (cruising around/mild acceleration).you can adjust the jetting very easily and you can get monster jets for holly carbs, cause they're used in such a wide range of applications.

Re:Running turbos in paralell...
I'm also interested in sb chevy twin setups. Met a guy in Naples, Florida w/a 70 Camaro, 396 running twin To3's. He used Volvo/Penta marine manifolds to hook it up and custom built a carb bonnet for the Holley 850 dbl. pumper.
I have a big *** 4wd blazer w/ tbi. 210 hp is way too weak for this thing but it will seldom see 4000rpm. Would running a pair of small turbos be a good way to go?

Re:Running turbos in paralell...
does the blazer have one of those low compression 350s?
my old 80 GMC sierra classic had a low compression 350. it was so slow :P, it had headers & intake & big carb. it helped a lot for tourqe but the ------- was slow
.
even if you ran one turbo it would be pretty cool. if you're using this blazer for a mud runner or something a turbo wouldn't be a very good idea. cause you'd have to spool it to make any power, and you would just lose traction. but if you're just interested in driving a fast truck, one or two turbos would be sweet.
