The 2 H2 examples didn't really show anything special, but it does have a cool factor.

| Post subject: | CASE REED S SERIES? |
hey, anybody out there done an s series case reed setup? I have the cages.. and adapters..made a set for use with an s motor already to bolt on in 'stock' location, but I keep looking at the spare sets of cases I have and thinking how much better an extra set of transfers up the back of the cylinder would be. I know its been done with h series multiple time sand I KNOW it works well there, but was wondering if anybody had experience with case reeding an s series? thanks. |

Henry is getting some pretty incredible numbers out of his. Oh, i'll do it, already have it planned out, etc...just wondering if anybody else has. |

It's probably hasn't been done because the amount of work involved, but I'm sure there are easier ways of doing things. |

not too hard. just basic machining and welding. I just want some legit transfer ports across the back, not boost ports. |

Watch the welding, seems cases do not like it at all. even when bolted solid. And the S series really perk up with reeds. Then all the triples do....lol

Best to take all the precautions you can. I know if I were doing it, I'd have a thick steel plate bolted were the cylinder studs are, plus a dummy crank shaft to match the bearings. I'd have them in place before even cutting holes in the cases myself. |

yup. got all that covered, good advice though. preheating is a huge must as well, and a dummy crank blank out of solid bar and rigid fixture plate. the fab really isn't the issue here on the cases for me, I know what im getting into there. I was considering using some of the alumiweld rod as it has a lower temp than traditional tig welding it, which is the other option I have. luckily I have learned a lot about these processes in the past few yrs. my concern was more with rear transfer port design. my thought was one large port up the back split into 2 smaller windowed ports (to act as a very wide bridged port) with a good hook for direction towards the center of the piston. has anybody done this on here with added ports? |

You will get more velocity with the split port, that's a good thing. I don't think you will find a lot of info on case reed conversions, as it is very rare. I only know of the two, Tom and henry. And the alumiweld is a good idea, have to have a heck of a torch though....  Probably not a problem.

It may be that even though the aluminum brazing rod melts at a lower temperature than the aluminum itself, the required torch heating would put more heat into the block than TIG would. |
