Yes.
I started doing a little preliminary grinding on one of the runner entrances not wanting to remove too much of the weld so as not to weaken the manifold...



And now that I'm going with the hemisphere, I can remove the rest of the square plenum. That will make it much easier to shape the runner entrances as it is impeding getting the Dremel at the proper angle.

I just LOL!

[JustDidIt]

LOL...Speaking of phallic symbols and alcohol...Hold up... need to shoot a pickleback...

[jetblast]

Five things ya don't wanna hear when you open your hood.....

1) Hey big boy.

2) Is that your intake, or are ya just happy to see me?

3) Whip it! Whip it good, as the Devo music plays.

4) Shwing!

5) Damn, thought I at least had five......

[tooter]

Here's a comparison between the runners...





The welds do overhang the entrances quite a bit, so removing them should improve the flow.

[jetblast]

Better start making some porting templates. I would be interested to see what the physical diameter gains are. Looks like a nice improvement.

[tooter]

Porting to the existing runner size increases the entrance diameter from 38mm to 40mm because the welds overhang a little more than 1mm all the way around. This nets a gain in the cross sectional area of just a little over 11%.

After all the overhanging welds have been removed, I'm going to smooth out and profile the entrances to more of a "bell" shape which should improve the flow even more.

That tooter looks great! Your experimental one looks like a jelly fish :p

Sort of does. Maybe I should call it the "tooter squid"... although that name has negative connotations. It may end up earning the name squid after I get the dyno results!

[tooter]

Cut the rest of the plenum off so that I could get the Dremel into the runner ports better...



Also gound off all the overhanging welds, and stainless steel bead blasted everything. This evens out all the grinding marks and will make it much easier to see the shapes of the ports while I'm grinding the bell mouths.

Before grinding...



...and after.

[Bluevitz-rs]

You going to smooth out the weld too?

[tooter]

Yes. That's the next step. I'm going to form bell mouths for the runners, but I need to be careful not to take off too much weld because that's the only thing holding the runners onto the baseplate.

[jetblast]

Too bad ya don't own a flow-bench so we could see the before and after results. That's gonna be huge difference. Nice job!!!!!

[tooter]

Sorry, no flowbench... but I am going to dyno the experimental manifold, so a few runs will show if there's actually any improvement. If not, I'll simply cut off the plenum and try something else as I also have another even more strange idea I'd like to try out if this one doesn't work.

Pure R & D is fun.

[Golddeenoh]

smooth it out then make it Phallic for Garm. for some reason that now makes sense...

[4/20 NEVER FORGET]

I love following this thread. Keep up the good work!

[tooter]

Thanks, man...
This whole adventure has been no end of fun and it's not over yet.

Ideas are always connected to other ideas, so it's simply a matter of implementing one idea to see if it works... and if it does, choosing another idea to implement from the other ideas which are connected to the first idea.

I'm also fascinated with "microbusiness". A microbusiness has all of the qualities of a large corporation, except it operates on a very small scale. First you come up with an idea, then you design the concept, then manufacture a saleable product, then use the proceeds to buy the freedom to do the research and development to explore other ideas.

A microbusiness has one huge advantage over a large corporation. Just one person exercises complete control over the whole process from concept, to design, to finished product. So all that's necessary is for one person to have a clear vision of what they wish to accomplish, and to simply be motivated by their own curiousity to explore the possibilities.

I believe that everyone should enjoy the fun of becoming an enterpreneur by cultivating their own microbusiness... something in which they are genuinely interested, and which can be implemented on a small enough scale that they can do it "on the side".

The American dream of being your own boss.

Look forward to the dyno runs. Would be interesting to see a turbo dyno run comparison also. Once I get this employment situation under control, I'm gonna have to catch you for one of those flanges to go with my intake.
