I really wouldnt think so, Garfield. The DSM76 will be even closer to what the 3065 will put out with quicker spool. If anything, the DSM76 will hurt the sales of the 3065 even more. English pushed the 3065 to 610awhp. On the same dyno, Brian is not that far away. The DSM76 should be right there with 3065. I dont know how much room was left in English's 3065, though. Theoretically, if Brian threw the HTA mod at his 3052, he would be right there with English's 3065.
Did FP actually stop producing the 3052? They still have it listed on their web page.
Its all speculation at this point, what happens on paper is tough to replicate in real life.
We'll see what the DSM76 will do soon enough, I have one on the way.
