Dyno'd the Magnum.
Cam specs sound good. Are you sure the stock magnum pistons are hypers?? I was considering a 150 shot with an MSD retard of 6 degrees but now I'm hesitant because the pistons are hypers and I have also heard that hypers wont hold up nitrous because they are too brittle???Is that it that, hypers are too brittle or what ????
Yes, Magnum pistons are hypers.
Hyper pistons will die before forged ones will due to detonation, but they are much stronger than old timey cast stuff.
I haven't done any power adder stuff on my Magnum engine yet, but the weakness of the hypers is vastly overstated in my opinion.
First off, I would not run a 150 shot on a dual plane intake. Maybe if it was the Zex perimeter deal, maybe.
That said:
On the Ford side, I have run 15 pounds of boost on hyper pistons and more than 150hp nitrous (NOTE: NOT at the same time!!)with no issues. But I had the tune right, so no detonation.
I've seen numerous LS GM motors take 200 hp nitrous without issue.
Work up to it, use good gas, take it easy with the timing and pay attention to what you're doing and I'm sure you wouldn't have any problems at 150.
But I'm not buying you a new motor if it blows up either. haha
