Re: What Turbo
The p-trim vs Q-trim is not much of a difference.
p-trim is 2.54" exducer/ 2.92 major
Q-trim is 2.69" exducer/ 3.11 major
Spool time should be pretty similar with the nod of course going to the p-trim since its lighter, but the Q-trim will be a good bit more efficient.
The diameters are not that much different, but the pitch of the blades is MUCH different. You can tell by looking at the blades that the Q would definitely flow more.
For the 231 Buicks, the P trim will out spool the Q trim by a good amount. The Q will probably make up for it on the top end though.
With enough stall, you could spool the Q on the street though.
