1128 Series Month

[MustangMike]

I'm guessing, but I already planned on doing some testing to confirm. Actually have everything I need, all ready to go, was just waiting for the time.

I think almost everyone has presumed the difference in performance from 460 to 461 (notably toque) is due to the transfers, but I believe this is not the major reason. They are over looking something more obvious.

FYI, here is the bottom of a 461 cylinder, it is fed from the bottom and initially only splits right & left (2 ways):

The secondaries on both the 461 and 661 are poorly fed by the case entry.

 

[MustangMike]

Yet they both run fairly well even in stock form.

That tells me the scavenging from the primaries does well.

Did you happen to sneak an 1138 jug in there? That's a build I want to see...

 

[MustangMike]

So, what does the Big Boss Man think (any thoughts Randy)???

I think some others on this thread are holding back!

 

[Mastermind]

Does one port a jug differently for a hybrid vs. an 046?

I use different numbers. Higher exhaust on a hybrid.

No sir. We are on 1128 duty.

I'm not sure the 461 runs any better than a 460. lol

 

[MustangMike]

OK, I'll be more direct:

What component can you take off of a 461 that will make your 460 run noticeably stronger?

Carb?

 

[MustangMike]

Carb?

We have a winner.

I put a 461 carb on one of my ported 460s and the difference surprised me, a lot!

I'm planning on conducting some tests, with the stock HD-16 carb, an HD-11 (044 arctic with a richer jet), and the HD-50 (461 carb) on both an 044 and a ported 460. My money is on the HD-50, but I hear the HD-11s also do very well.

So, we must do some testing! Soon!

I got a hd11 when I decided to build a hybrid. I was told that was the best one for that build

 

[MustangMike]

Maybe I will test that also, problem is I put a 461 control lever in the Hybrid when I installed the HD-50 carb, so switching carbs would be tough.

Conversely, I switched the choke lever on the HD-50 I put in the ported 460, so I can easily swap that carb with the other carbs that use the 440/460 control lever.

I think both the HD-11 and HD-50 will out perform the HD-16 (stock on many 460s), but I would be very surprised if the HD-11 makes my ported 460 run better than it does with the HD-50, but we will see, I have em all now.

I've heard some say they are a gain and others said they seen no difference

Awesome I'd be interested in the test

Would be nice to see what you come up with Mike

If you dont mind me asking, what do you run on your hybrid?
