Been offered some turbos, very close to -9 specs. This will be a on a 34. -9 are as below and this reads comp to turbine.
Garrett 707160-9 44.46 - 59.41 56T 0.42 42.4 - 53.85 62T 0.64
But what I was offered has 60mm comp wheel and a 53mm turbine wheel. Bigger comp wheel would normally mean more power, but in the same size housing will that mean more response and more power or more response and less top end as it will choke out.
Likewise, the slightly smaller turbine wheel tells me a little less response, but flow better top end in the same housing.
Any guesses on what the characteristics will be?
