Re: Ported Dart 215 pro1 platinum with port energy discussion 2.0

It's been around since at least the late 60's, DV used them in his Pinto heads way back when.

You can use it to speed up air mid port and stop the wing short of the short turn to slow the air speed and help make the air turn, it also splits up the river of fuel that runs down the floor and over the short turn.

Good for him.

Yea Gary I'd like to know who this clown Headguy is.

Some think he's warp's alter ego... I don't really care, he obviously has nothing to add but smart @$$ comments and I have nothing to prove to him or anyone else.

He does seem to be very anti education so he probably has a hard time learning anything new.

He knows nothing about head porting. Probably a grunt that sweeps floors in a cup shop.

I recall a rumor like that going around sometime back.

There are enough people here that want to discuss tech and try to learn so it's probably best to avoid the others.

I don't know if it helps or not, but this just made 880hp on a 437. Straight up 23º with a 2.140 valve.

And 100 shot of funny gas

You need Darin to tell you? Or will you call him a liar as well?

I remember talking to Darin when he did his pro stock heads and I ask him how many people he thought would grind the wing out because they didn't understand it and his reply was... "most"

[randy331]

I took nearly 500 rpm swirl out of the port with floor wing, calms my kite string when near the floor. Will it make more power? I don't know but with the swirl about 2500 rpm at .7" I figure that is plenty. The calmer string tells me the floor is a bit happier and the bench doesn't pulsate after 295 cfm as bad. Thanks, Charlie

Dyno it, then pull the heads, grind the wings out and re dyno.
Sure be interesting.

Going backwards helps point the direction forwards. LOL

I remember I did a few 2.8l Chevys ages ago they had fins on the floor and the Chevy power book detailed how for max performance the fin was to remain. I just shaped them a bit and ported the rest of the port.

I would have a stroke if I did that and it lost power! Ugh the stress.

[Carnut1]

Worst case I pull em back off and buy some epoxy.

Thats the only way to know for sure if it helps or hurts a particular port.

[user-9274568]

This is my favorite winged head I have!

Blanketly applying something Darin did to a set pro stock heads to other applications may not be the best approach.

I remember him saying he "believed" a port that stalls at or below the lift the engine will run is bad for power. I don't question what Darin said about the applications Darin came to that opinion on,... but now it seems blanketly applied to every engine. Now a guy running a street engine with a .550" lift cam thinks they need heads that flow to 1" or they'er gonna have a turd. Yet I've seen heads that stall badly make way more power than ones that don't stall. So maybe we should be discussing , when we will take a port that don't stall over xxx, or what all we'd trade to have the port flow to 1".

Floor wings would have trade offs too.

You guys sure are trusting of epoxy....I would be sweating bullets the whole time driving wondering if this was the pass the huge chunk of epoxy breaks out of the head or not.

[user-9274568]

I'll say it.

The head needs to keep flowing, period. I don't care how much lift you have, period.

You take that cylinder head and it will work on anything, period.

You design a head for a floor wing, period.

You take that wing out you hurt the head, period.

But I do things all wrong, period.

[randy331]

Isn't period a bad time of the month ?

Cumbersome
fact
i'm out
