Single Turbo or Twin Turbo?

[Wez]

There is a whole world of difference between a well setup single a stock based motor, its not really something you can describe, I would suggest trying to get a ride in one

 

 

EDIT: my latest dyno plot from SRR is in my sig if you want to overlay.

Here you go Nic if you want to overlay my graphs over yours (the lbs & bhp are on different scales)

 

He's one I prepared earlier

 

The red line is a BPU Supra

You will actually find that a well setup Single has a very linear power curve...like Nics, its a very smooth power rush

 

 

With Hybrids its like Wack.......WHHACK, it feels almost juddery

That pause loses you a lot of ground against a a single, plus you aint pushing more any power in to the bargain

 

That might just have been the way the Hydrids I were in mapped, but I would bet thats across the board

With the right turbo choice, a single can be just about as responsive as the stock sequential setup, eg. I get positive boost on mine at around 2000rpm. Infact I'd hazard a guess that my GT35R is similar if not more responsive than a pair of hybrid turbos.

 

Also the power is a lot more linear and controllable with a single turbo compared to the stock sequential setup. I'm sure more than a few accidents have been caused by the second turbo on the sequential setup kicking in unexpectedly.

 

Wanted to see that. Nice post.
