Precision mmmmm..................... Garrett have just released a range of billet wheel turbos, I think the smallest at the moment is the replacement gtx3582r. Good for higher pressure ratios:devil:

Can't seem to get the link to work:-(

It's not just that it's a billet wheel most new wheel designs are alot more efficient than older stuff.

[Rob@Backyardracing]

tbh, i would say no, a bigger turbo is always the way to make more power, these billet units make more power for the same size, so in drag racing if a class is limited to say a 62mm max compressor, then the billet version will usually make more hp for its size vs the non billet jobbies, but its not much, we switched to a billet unit last year, and the gain was minimal. the theory is that the blades are thinner, and the part of the compressor where shaft comes through is narrower, (they can make bits thinner vs cast and still retain good strength) so less un-productive metal on the wheel, and more flow.


but as i say, bigger is still better imo :D

this is true, but its usually at the very high pressure ratios where they really shine, most road cars wont get into those pressures id guess

Big turbos ftw, I don't have the bottle to try a 72mm on my b16 though, I will have to settle for a 67mm. Lol

[Rob@Backyardracing]

67mm is plenty, im sure youve seen the numbers "true street" class knocks out :)

Yeah should be sweet, plus I don't have enough money to run a 72mm turbo either.:laugh: The drive train is going to have a hard time as it is.
