How ya been
Its been a while, I don't come on here much these days.
I see the slings still working great.
I thought maybe you sold it as there was one very similar for sale in Chicago area.
Heard Mitch took great care of you, you should see the 377 after he gave it a once over... what an awesome guy.

I tried a set of maximus way to much prop (diameter) and it might as well be a #6 cleaver it weighs a ton.
Spool up suffered big time.
thanks for the insight on the B-max drives they have been flawless since Ron Bender fixed all of Dean's BS

With the B-max drives
its slow now
stock 30' B1 5200RPM 92-93gps (4) onboard with coolers & lite fuel
I'm fine with that, turn the key and drive.
Take care
SK
PS if you want to sell those herrings let me know I'm looking for exactly that pitch and style
they were the best Wheel I ever had but with the 1:30 B-max I couldn't spin them.

yea Im not on here much anymore either,got back into drag racing etc, Yea Mitch is a good stand up guy, and he does what he says and gets the job done fast.I ended up with to much $ in the Herrings,Ill never come out, I figured i catch some used maximus for sale, just to try, the Herrings are pretty thick, Hindsight should of sent them to herring let them loosening them up,I dont like lugging down the motor that far,Ive got to a point Im not running hard and not trying to make anym,ore power or speed, guess getting old and tired of $$ outdrives,lol

Rob

sorry for the OT

Hi Dean - Can you tell me what speed are your seeing with those 600Sci's?

Found a set of B blades labed 26 5 blade Maximus But I think they may be a little to low of a pitch for stk 500 efis and 1 in imco,s A stk 30 4 blade is not enough and a merc raceing labed 31 s hit the rev limiter . I think I'll need a labed 28 5 blade.

I've looked at several dyno sheets from other members who built stroker motors out of the 500efi and shared the info. The manifolds don't contribute to HP after 5300 or so. I just went through the fuel system and had the injectors cleaned. In 90 degree heat, mine seems to be running strong up to 5200 and then seems to hit a peak. I'm thinking of trying a set of 32 Herrings on mine.

32 5 blade hearing, on stk 500 efi? I have a set of 29 hydro 5 blades that are labed . Couldn't turn them but 5000 at 80. But who knows if they are loosend up or tight labed. The came off a cat .

I add 2 deg of timeing it seems to help in the heat. But who knows. I doesn't soot up the transome as bad.
