when most people talk about turbo systems they say that a turbo will make 50% more power at .5bar or 7.35psi.. according to this when you put a drag3 kit on a GSR you should make about 70more hp and have a total of 210hp@ 7psi.. but we all know in real life a drag3 GSR @7psi makes about 250... this was just bugging me cause it would seem our turbo kits are 75% efficient..

 

GSR's making 250 hp at 7 psi are few and far between. Importreview.com has a bunch on GSR turbo dynos, most are around the 220 range.

 

It's all in the tuning and component selection. All those numbers are estimates and averages. Every car will be different.

 

look at mazda miata gains and you will think our gains are lacking.

145whp to start for us...7psi stock exhaust we get about 220whp
110rwhp miata 7-8psi 218rwhp now how is a 100% gain for efficiency (guy named jason)

ask the miata guy on the board about them.


i am more then happy w/ my gains dont get me wrong.

 

I have seen close to 300whp for a 7psi turboed GSR. 100% gain. I find that baffling as well.

 

And who would that be?

what kind of total hp would I be getting with my d16y8 at 8psi-9psi with a Drag kit and 310cc injectors? Right now I am estimating I have between 130-135 hp.

 

or how bout a 75shot of nitrous making around 220hp??

 

Not saying that nitrous is totally bad, but I would rather have constant boost whenever I want it w/o having to fill up the tank every once in a while.

So anybody have any answers or estimates for my question above?
