boudan Regular Location: Brisbane Registered: June 2003	Triple Turbo Theorem Sun, 08 June 2003 01:13 Having read, which could only be described as a fair few, threads of this forum, I was surprised to see that a *Triple Turbo* conversion had only been touched on in a passing comment... Many assumptions have to be made when calculating the enormity of mathematical equations required to even begin comprehending such a conversion, however I will try to post my idea. The Easy Bit: On second thoughts, a fair few more mathematical equations must be completed before choosing an appropriate configuration, however for the sake of argument I will assume that the turbo’s will be of (ct12a small), (ct12b medium), (ct26 larger). Factors to take in consideration: ceramic vs. steel, ball bearing vs. high flow, oil vs. ??? Assumption 1: An aftermarket system that would be capable of controlling such actions to my knowledge doesn’t exist, the logical response would be to create / re-program an auxiliary function. (More on this later) The possibility of having a split intercooler. Theory: For those who have already tuned out contemplating that a triple turbo system is absolutely not possible, Henry T. Ford hadn’t even contemplated turbo’s, they simply didn’t exist. And as far as I know, the possibility of a triple turbo system being widely adapted to cars is ludicrous, however on a jet boat where high speed are normal, the stress upon smaller turbo’s would surely reach detonation. With only using large turbo’s we all know the sacrifice of low-end boost and spool up times that would even make Grandpa Simpson shiver. The application only holds relevance to forms of drag racing where 10th’s of a second determine 1st and last place. The Answer: We hear turbine assisted car enthusiasts squawk and squabble about the best turbo combinations that provide power band over the broadest power curves. The latest modification is to replace twin turbo’s with a larger single or hybrid combination. Critics may pose the question, 3 turbo’s? Isn’t that excessive? Quite frankly yes it is, (if) you plan to run them all at once. Cleary it is a question of money, but no one has taken to the challenge of having their cake (edit: turbo/s) and eating it too. A turbo system designed to cover low range, mid range and high range, is predominantly a twin turbo system. How so? First we must understand the manifold order of the turbo configuration (A): the small turbo (B): another small turbo or mid sized and (C): the big fella. There are two orders possible, ACB or BCA, the reason for this being the brainchild of such an idea. (A) & (C) turbo’s must be used in tandem for perhaps a spilt second or two, hence the reason for being located next to each other or sharing the same inlet manifold piping. Low end: (A) being a smaller turbo will spool marginally quicker than (B), (C) at this point in stage will be closed providing (A) with enough piping to adequately create turbulence for air to feed into the manifold quicker. (B) will being to spool while (A) has provided boost for the required low end response. The car will hit mid-range feeding from the pressure created by the now fully wound (B). (B) will carry the boost out-put to a level where pressure goes beyond (A)’s capacity. If we imagine the Y shaped piping between (A) & (C) acts like the butterfly in a throttle body, for those who cannot get past the idea of Y shaped piping, I can only describe it as a reverse 2 into 1 much like your headers or exhaust plumbing. For a split second or two the throttle body will transfer the pressure being fed to (A) through to (C) before closing the (A) piping completely. This may not of course apply in reverse while the car slows, and pressure is reduced. The sheer pressure from (C) would not do wonders for (A) and therefore must be vented to the atmosphere while the butterfly then closes (C) and allows (A) spooling gradually. Meanwhile (B) has been sustaining an acceptable level of boost between (A) & (C), and should be consider the main focus of such a system, a failure in (B) would result in well a failure is a failure. Other factors that could be adapted to into the equation could be the addition for a separate intercooler, however my small brain has not figure a way to combine to sperate intercoolers unlike the turbo. Recommended number of cylinders: 6. Twin turbo’s exist on 4 cylinders likewise single turbo’s of 6 and 8 cylinders, so nobody can tell me the appropriate metal craft cannot be fabricated. It is all a matter of money, and an aftermarket computer that could use pressure sensors / rpm indicators as far as the switch between (A) & (C). Any feedback, thoughts, comments and criticisms are welcome, as they help as all to understand the complex nature of such possibilities. If not, perhaps I have provided some half not boring text that has wasted some 5minutes of your time while you wait for the kettle to boil or the lackey to bring back the pies.
