any 996 turbo projects tried to switch to a large single turbo ? if so what was the outcome ?

 

Interesting question.....

 

umm.. like a HELLUVA lot of lag. Drive a 930

 

where would you put it?

 

Probably just place it behind the rear bumper off-set to the left a bit like the 930.

A better question would be how would you plumb the intercoolers...

It wouldn't make sense to run a split and retain the stock fender mounted ones, all the piping would create some serious lag.

I suppose if you're building a drag car, one monster turbo with a high-speed stall in a tiptronic box would probably be pretty gnarly and have gobs of top-end. You could use a nitrous spool-up kit in conjunction with the high-speed stall to offset quite a bit of the lag.

In the end it doesn't make much sense except to "be different".

 

Where would you put the intercooler?

 

Has anyone tried a Bi-Turbo setup?

 

The Kramer K3's (935) were capable of be interchanged between twin and single turbo applications. Both twin and single turbo forms made close to 1000 HP and had a 3.3 liter based block.

 

You would put the intercooler over the motor and run a single unit. The lag would be terriable. Not worth it. You want BIG power run a coiuple of GT35s and call it a day.

 

I love my single turbo 930 and 965, turbo lag an all.

I still have full boost in my 930 cab at about 2800RPM. Not too bad.

 

I am running motronic with a GT35R in my 1992 965. Full boost at 2900 RPM and a tire shredder in just about every gear.

 

Not bad, We do a conversion like this about once a month. I currently have 7 EFI conversions I am doing!!

 

I just finished the conversion (protomotive). I thought long and hard about going with your EFI. But I have a protomotive shop right by my house. Both systems have pro's and con's I like the idea that Motronic is still somewhat true to Porsche but I think the EFI is a more complete package. I have to run a stand alone traction control (system from England). Where, you do not.

Y65MPH-- can you elaborate on your traction control? Don't mean to hijack thread.
Coincidentally I can guess where thread starter is actually coming from with the question he poses -- Big HP Nissan GTR and Supra's are often converted to single turbo and reach astonishing numbers-- hence his question. From my experience modern engine management systems and turbo technlogy in general have put the lag of the 930 in the past.Perhaps the question could also be asked- would you convert single turbo(ala 930) to twin if you had the opportunity?
