Yep confirmed to be as good as fwd bluetop

I hinged my bets by using blue, red and silver top parts in mine, so as long as black tops aren't judged to be the best, I'm covered.

I want to be an anyport barry, put me down as a 4A barry as I can confirm yesterday I put 3 kids and a mother in law in me 4AFE ae101 and the extra weight slowed things down considerably.

Lucky its not the 20v version, else you would still be in the driveway suffering for smoke inhalation

I once swapped two spark leads on my fxgt, legit took me about 10 km of driving before I noticed.

 

Other than that the second gen bigport went hard for what it was.

[Spencer]

So not that hard?

 

[ajg193]

Every time I got the speedo off the clock I'd have to back off pretty quickly as something would get very hot smelling

[kpr]

Pretty sure I said bigport 4age barrys not general  barrys

In other news the heads are still siting in the same place on my bench, because yuck

On the plus side, they're not in my shed.

Stickers making cameos in Garage 4AGE vids. 

I've made it. 

[kpr]

Place your bets..  will this:

a) work
b) not work
c) wont do shit
d) fall off and end up getting stuck in the valve

 

 

[ThePog]

A, b and d.

Also I fully loled at the wee tvis animation on that last vid.

[Vintage Grumble]

What's going on here then, you making a medium port?

[kpr]

2nd pic is a smallport flange in front of it.  So im gonna try my smallport manifolds on it with just the flange to adapt them.    then will weld those bits to the flange so it fills in the dead space and try again.

will use said results to decided how im going to modify the ports

[xsspeed]

are you fucking with the 2nd or 1st gen bigport?

[Sambo]

There was a fella on Toyspeed who reduced the size of his smallport intake valves ... something something helmholtz.

Edit: intake ports, not valves.

 

It was an interesting theory, but I think that in this situation the vessel (runner) length would be a better variable to play with, rather than restricting the intake to get the resonance you wanted.

[xsspeed]

Yeah I recall someone jbwelding their port or something lol

The early head. It's a better starting point to modify. I may try the other head when take this one off engine to modify it

Redmist or something similar?  had that offroad race buggy?    I tried the same way back. but likely made an abortion of it. just made it go worse haha.

That's the guy. He did a fair amount of R&D on the smallport in his buggy. I don't recall seeing any dyno numbers, but apparently it went hard for what it was. 

There's plenty of examples of race and rally cars that have had their ports reshaped using Devcon and other 2 part epoxy type stuff. A lot of the time people do this for flow direction (eg downporting to point directly at the valve)) as much as port size/shape. There's got to be a few rally Barries around NZ who have gooed up their bigports over the years...
