Hybrid Build

[KG441c]

Thanks Joe. I've become a 372 snob, but my hybrid is as strong as most any 372 or 461. The key to a strong hybrid is very short blowdown, long intake, and timing advance.



The hybrid starts at 2:10

Awesome runners!

Brad, are both the 461 & Hybrid ported???

You are a mean man sir .

 

[MustangMike]

Well it says "brand new 461"???

I've only used Motoseal. It seems really thin. Is Dirko thicker? The stuff Stihl uses on clamshell pans- after they're removed is nearly in the same shape as when it was applied. Motoseal kinda flows all around lol

 

[Adirondackstihl]

Dirko is stihls proprietary sealant

Thicker than Motoseal?

Didn't you just say that Motoseal was like water or did I misread your post?
I've never used Motoseal, but from the sounds of things I bet it doesn't take much to find a heavier product.

I've always used Yamabond 4 myself

I haven't actually used the Dirko yet, I got one tube for a customer and one to stick on Ebay, since most people haven't heard of it I expect it will be there forever or until I run out of 518 one day and give it a try
Am I right that permatex and Loctite are the same company and just have different names and numbers for different markets?

I did say it was thin. I didn't know if other case sealants were as runny or not. Motoseal is all that's available locally so when I run out I just get more. But I've been contemplating using something thicker. Looking for recommendations is all

The motoseal is messier but easier to apply than 518 but the 518 is tackier and stays in place. Using motoseal a saw can be started shortly after a saw is put back together but 518 8 let set overnight

Yes. My 461s are a bit stronger now. It would be a very close race.

 

[blsnelling]

518 doesn't tack like the others, giving you more work time. I find it less messy as well.

Thanks. Yeah I've always started mine within a couple hours of using motoseal. No failures yet so I guess it's an OK product

Just givin ya a bad time Mike

Yes we have motoseal, yamabond 4, and 518 in the shop and I by far prefer to do a cylinder with 518 even it it needs overnight setup

I've never waited either. I fire them up immediately after assembly and never had an issue.

I would agree with ya about everything but the long intake, I like mine in the high 70's

 

[redfin]

Will 515 work also on a cylinder?

Wondering the same. John deere recommended 515 for my reverser pan. I looked at specs between 518 and 515 and I cant see the difference.

Never used motoseal but dirko is some thick sh!t. I use dirko and 515. I don't like the smell of dirko...
