SB Products Billet SuperJet engine case

[wsuwrhr]

After a year of development, 300-400 hours of design and machine time, I was finally able to finish the first billet Superjet case that I know of.

I started out with a 16MM crank, but these cases could be used with any stock stroke or stroker SuperJet crank.

I tried to remain true to the look and feel of the SJ case and to keep them within 5 lbs of the factory case.

Uses all factory bolt-ons including, cylinder, intake, ignition, mag and mount pattern.

As some of you guys know, I manage DASA's machine shop and I run my own shop as well. So it should come as no surprise, I built the transfer base to match the DASA/Lamey cylinder, but I could make it to match any cylinder.

What do you guys think?

Right out of the machine in this shot, still have to drill the starter mount holes.

Intake side. I made a crank girdle to stiffen the bottom to keep everything straight for the big ass crank turning 200HP.

Crappy shot, head slid off to one side. Mag side

I don't have anything valuable to say... other than WOW those are nice!!! I'm sure this will help some guys go to the next steps... and thanks for putting in the time!

i know how much work would be in the drawing alone
very impressive

i just had a moment when i saw those


ok how much

 

[waxhead]

can i offer a sugestion
since your taking a plunge from the front

put a oring groove in front so you dont need a front cover gasket

I think retail pricing will be at $2800.

I may do that.

 

[waxhead]

its just a problem area on the stock cases
and a o-ring would fix that

I second that...

I just want to add.....

These pictures are from mid-October, at this time the cases are nearly complete. I have been swamped trying to finish the details of the case and lightening them up where it is safe to do so.

I have a total of three cases, I am trying to decide which builders will get the first three. I am going to start the first production run at 10 cases, unless I get a few people ready to step up.

I can imagine the torque this thing will make will be significant, pumps and props will need to jump up pretty big to keep it pulled down enough. The bottom hit like a train and the top end will just keep pulling.

oh hell yes 1200cc of pure power
it will be sensational
A dry pipe and a good set of carbs
Will make a nice race engine as well

Thanks for the cool words,

and you're welcome.

Hopefully I will sell enough to break even!!

Probably need to revive Dan's billet 50+mm carbs

OK i dont think i have seen those
But yeah it would handle 50s just fine
I would love a set on my stroker race superjet but i dont think i could handle the power
Are you using 6061

Yes, 6061-T6 plate.

I was thinking of annodizing a set just for the fun of it.

I think it would look cool.

 

[waxhead]

yeah hard anodizing them black would be awesome
and they would always look good as well as they wouldnt corrode

i may look at a set when i turn my 2008 superjet into a gp boat

 

[HBCwatercraft]

For 2800.00 will they be preported for ur lamey heads, or close to if asked. Im savin
up now. Very nice work.

I take my hat off to you Brian I know exactly how much work is involved, I keep looking at cases thinking I should have a go but it takes about 30 seconds to talk myself out of it. Nice work.
