From Robar:
GPower was in LA last week to assist in the build of this S3 at Southbay Autohaus, the official G-power installer on the west coast.

WOW... Sounds Great.. What kinda numbers does that setup put down??

 

Thanks for sharing!

 

That's a surprisingly clean kit. How much power does it put out?

 

Nice set up.

Slightly off topic, but when did superchargers start being made like that?

 

Amazing kit!

Very clean looking

 

Can you explain the difference between the stages I, II, III or what is being referred to as S3 (kind of like a Dinan term)?

What are the power expectations for each stage?
It appears that stage III is with full internals done, ie. lower compression?
What compression ratio is run on such a stage and boost levels?

Sorry for all the questions but there are specific comparison interests.

Thank you
