That's not necessarily true. People have a misconception of that,though twins do tend to spool faster, sometimes they will and sometimes they dont. But still a single that pushes as much air as a twin setup will take longer to spool. In most cases with a V configuration engine per usual is twin turbo's. Whether it be a V6, V8 or V12 or the mighty inline 6. the inlines and most engines that are twin turbo are usually race engines that have about 2000+RPM capability more than the CDW-27. I see many single turbo setups with a V configuration though, and i beleive mainly that it is a cost situation. I can see a possible Twin setup for the tour, but it would be expensive and tricky. not to mention a whole lot of R&D would have to be used up to develop the system. Besides, the idea behind twin turbo is faster spool up and higher horsepowers, the first turbo in some setups, has a smaller turbo for low speed, low RPM power amplification. and at higher speeds, the larger of the two turbos kicking in with the exhaust at high rpm, creating killer horsepower. Beside that, I personally dont think that the kid should be discouraged from trying something if he wants to and has the money. Use a small stage turbo for the low rpm acceleration, and then find yourself a bigger profile turbo that can flow a large amount of air and hold on to higher rev's without overspinning the hot side. I guess innovation is the biggest factor to twin turbo on a car like this...without innovation you guys wouldnt have the impressive streetflight kit, so dont discourage him....help him....Think about the space under the front clip, find some space and figure out how to mount them and run the necessary piping to an intercooler, to the TB, and the exhaust really shouldnt be too hard to figure out. and yes feedback on this incouraged as i know how you guys like to knock any radical idea. But turbo's are compressors of a fluid (air is a fluid). I deal with liquid (fluid) compressors mainly on a daily basis, but essentially its no different from a turbo or supercharger. something at a specific pressure goes in and is compressed even further and pressure is added, and then discharged to the system(engine) in this case. Anyways to end this post, the twin setup may or may not be better than a single turbo setup. you won't know until you try.( dont even bring up the M12, i know its twin'd and it uses t25's).
