Single turbo\'s and ecu\'s!!!

[sadgoth]

asked this on anoth thread, but hypothetically (at the moment anyway ), could you use a Supercharger and T78/T88 that way the Supercharger kicks in constantly, reducing lag. I believe similar was done on a Sierra Xr4x4. Anyone ever tried it on a rotary?

Mark is thinking ahead to the TII having a BIG turbo!

It is possible.

Nissan did it on a Micra - it was called the Micra Super turbo. Japan model only, dont think there are any in the UK.
(based on the K10 model)

The power delivery is so much smoother (than the stock twins push/wait/push) that good throttle balance and control of the car, especially on track work is a big improvement.
 

I\'ll take you for a spin* in mine now it\'s all mapped up - no kick from the secondary tubby just one big push (okay, not a BIG push like you single guys).  I reckon you\'ll be well impressed about the transition!

I often think people substitute  the word \'smooth\' for another word beginning with \'s\' when talking about cars and in particular twin turbo\'s. ....\'My skyline has such a smooth power delivery\' - yeah you mean it feels bloody slow.

Only joking though, the twin turbo setup on an FD is one of the finest, just hard to look back once you have seen the single turbo light.

When me and revbaz went out the other week in his to4r 1.15 a/r housing I put the car in 2nd gear at 2,000 rpm I floored it I think we counted to 5 seconds before we got any kind of response from the turbo and when we did it was worth waiting for:D  that\'s the kind of lag i\'m on about, nothing until 5,000 rpm.
I kind of like lag now anyway it gives a good sense of suspense. You know something is going  to happen but you don\'t know when:D

If you have got lag,you are in the wrong gear,no lag beyond the redline.

Valid point Tim.

Put a boost controller and ECU on your stock twin car and  the acceleration is silky smooth - yuo don;t notice the transition, and as you tend to add both these things when you go single ...

Well said that man

Its not like singles are dead below 5K as a rule, and if yours is big enough to the point that it is - drop her down a peg!

Do you really need 1bar on a big turbo much of the time on the road any way??

LOL, got to take you out in a serious Skyline GTR man and show you the MEANING of lag.

Tim wouldnt lower him self to be seen in one of dem things!

Of Course, if you want to run on really low grade fuel, and get a bit better efficiencythere is a  step modification.

Ditch the existing 13b engine and gearbox

install an automatic gearbox

Get a really big turbocharger, just about the biggest you can get in the engine bay.

lengthen the  shaft  of the turbo, so it can meet up with the input shaft on the gearbox.

cannect the output side of the compressor to the inlet side of the exhaust rotor. (dont know the fancy words for that bit.)

set up the Injectors to pump fuel in the connecting line just mentioned

install a continuous igniter just in front of the exhaust turbine.


Probably want to run it on paraffin

Sounds like the scrapheap challenge
