v-1 the impellar was cut diff. from the v-2, so that is why it is quieter. the t trim is just as stated earlier
Are you sure about that? I don't think that's exactly right, but I could be mistaken. I think there are other factors that make the V2 quieter. You may be referrring to the difference in the GT and Cobra versions of the V1 and V2. Cutting the impellar, to my understanding, affects the boost. Which, is exactly the case in the V-1 SC and V-2 SC. The V-1 s-trim (and V-2) has staighter impellar blades which make more boost at lower rpms, vs. the V-1 SC, which has the cut impellar to not allow it to make as much boost until higher rpms, which is where the Cobras need it more so than GTs.
If you challlenge my thinking/information, I will be forced to research and find out for certain. I KNOW that is the difference in the GTs and Cobras S-trims, but I don't know what is PHYSICALY different in the V-1 nd V-2. I only know that the V-2s are the SQs and are quieter (is that a word?) than the V-1 versions.
