Default magnum

I had a 93 challenger which was a 27 magnum hull stretched out a foot. The challenger was a bit heavier with the deck being defferent and the way I had the cuddy finished out and I ran a solid 67 with brovo 1's. After engine upgrades it ran 79 radar.

A friend of mine some time back had a 21 4 winns lib with a 454 - 330 HP alpha drive and he never had any troubles. Just take it a little easy on your re-entry. When I ran the bravo's I would leave them pinned and let the engines hit the rev lim. within reason. The alpha's you might just be a little careful.

Back in the day a 27 with the 330 TRS setup would run mid 60's. I never saw one with the Alpha's, but I suppose it could be a bit faster.
