Turbocharger upgrades

FWIW I went external wastgates from the off. The turbos are from Todd at Protomotive in the US

For my own application we are just seeing the sweet spot come about at the higher boost levels. IE when they start to compound upon them selves!!!
 
Faried what sort of boost levels are you now running? I read somewhere the efficiency range on the 3076s does not start until around 1.5 bar!
 
Tom

A regular 1.3 to 1.5 depending on map. But upto 1.8 and above a little if wanted
 
I currently have a 1.1 bar map, 1.3 bar map and a 1.5 bar map. 1.5 bar is just savage! I wonder what 1.8 would be like :?: The difference from 1.3 to 1.5 is mad!
 
Lol. We are seeing about a 100 bhp increase with each 0.1 increment.

1.8 is hairy and only for special occasions !!!

Tbh. 1.3 is enough for the road and very quick
