I know that imco rates them around 900 hp.I would like to know at what hp are people pushing them to.Has anybody tried pushing them past 1200 hp?

Im in line for this drive as well.

I have a friend building a new 1000HP 27footer using it.


CBBLR now has 961 HP and has an SCX. (I think)

Pretty sure 26 Redline blew one on his cat. At least I think he has an SCX, I can't keep up with all the acronyms. PM him or read through all the Desert Storm threads.

running just over 900 thru mine and zero issues so far.

I guess someone has to be the first to try and run 25% more than rated HP thru one though it won't be me

26Redline did have a SCX fail on him... it wouldn't shift into or out of gear at about 4 hours. It was extremely difficult shifting from day one. I believe that his drive was defective from the get-go, and is now being warranteed by IMCO.

I have put a SCX upper with a SC lower behind a Magic cat with a 1203 hp 598 in front of it.. with no problems shifting or otherwise. It shifts extremely smoothly.

I ran my SCX upper/ SC lower on my Heat behind 750hp with no problems and smooth shifting. I lost zero speed as compared to my SC upper.

I just re-installed my 600sci, Stage VI whipple motor which dynoed at 960 hp in the boat, and will let you guys know how it goes.... so far...so good.

I just installed a SCX on my DCB F26 w/TCM800. Still dialing in some issues. Shifting is not one of them.

I wonder if the -3" SC lower would fit with some cutting or a 1/2" spacer? I'd be a gunner on a pair of SCX drives if so.

Uncle Dave

Heres why Im upgrading-

54 hours....Didnt break, but wouldnt have lasted much longer.

My rigs pretty mellow compared to some of your guys.

I ordered mine I was going to order the complete SCX but after IMCO said I would likely lose 5mph at the speeds I expect I just ordered the upper. I am putting my -3 lower on it. I talked to Brett@BBLades before making the decision, he assured me we could make a prop work well. He is cutting me down a test prop and sending it my way ASAP. So yes you can mate a -3 to the stock upper. I think he said a 14 3/4 diam would work but don't quote me, he said 1/8" is min and would like to see 1/4" between the prop and cav plate.
