Tuning for bigger turbo questions

[RobertTrivanovic]

So i just put on a bigger garret onto my sled instead of a cheap G kit tiny turbo. I had it tuned pretty good before, would a bigger turbo need more fuel less fuel or almost the same? This probably sounds stupid but im running the exact same boost as before, so would it really change that much?

Just want to be safe fore my first ride this weekend on a fresh rebuild too.

I'm not sled turbo guru.


BUT if it follows the same concept as any turbo(cars and trucks) you'll be adding fuel.

A larger wheel or "better flowing" turbo will push more air at the same psi and less effort.

it's like watering your lawn with a garden hose and then using a fire hose.

I was just confused because I sent tss an email about a few things a while back and they mentioned taking away fuel, I feel like they just mixed up their words though, never really questioned it.

Go look at a couple turbo maps. You will see larger wheeled turbos will produce a larger amount of air with the same psi. Also will product it easier and less heat on the turbo
