I will let you know for sure in a couple of months, I have a "twin single turbo kit" fitted to my car (plenty of pics on my build) it runs two KKK turbos, it is a relatively simple set up you just split the oil supply, the FD already has two oil drains and then all you need is a good manifold with a single external wastage.

I should be doing the first start up next month and tuning the month after.

the theory is that a smaller turbo will spool up faster than a larger one so two small one will create maximum boost much earlier, whether this works in practice remains to be seen but as i will be using the car for drift i am hoping it will give me a strong torque curve at low revs.




Now back to discussing what a bad idea it is

You misunderstand.

That parallel twin set up as you describe is the usual and its fine if a little complex and busy.

What is a really really really bad idea is to use 2 turbos each with its own intake path from the turbo to a front or rear rotor independent of the other turbo.

You would have to run 2 engine management systems to do it *safe* and then you could still be running different power levels front rotor to rear rotor on the engine and it will crap it out harmonically and break stuff/back off dowels/bolts etc (been there on that one).

All for zero benefit.

 

Cool article, thanks!

 

pet project for probably 2016, is to translate some of those. there are lots of neat tech articles in the Rx7 magazines
