porting question
 

has anyone removed the bridge between the ports on a 6 port engine? dont tell me not to do it, i just want to know if anyones done it and how it worked. i heard someone has but cant find the post.

Ive seen pictures that people have posted who have merged the two ports - never heard of any testimony after they re-installed it. Which indicates to me one of a few things:

- They never actually finished
- They finished, but it wasn't at all what they'd hoped so they kept their mouth shut as opposed to eating their words
- They ported incorrectly while finishing and screwed the iron, or it ate a corner or side seal in a few kms.

Since you asked, I won't tell you not to do it.

I would think it would flow terribly.

i actually just found a picture of a bridge port kahren did which looks like he eliminated the devider between the ports

use plexiglass, trace your intended port onto it and lock in to the engine with the 2 dowels so you can see where the seals on the rotor ride when they pass over the port. ;)

thanks for the tip.

..really im still wondering who has done this and the true results.

another huge port from kahrens website..

I can tell you roughly what the result would be if you combined the two ports with no way to close the upper section lie in stock form.

Huge amount of reversion, virtually zero power below 4-5,000rpm, screams to redline however. Idle (and everything actually) would be impossible to tune without a standalone.

again .. i just wanna hear from people who have done it or road in a car with it done. also if they have ran a turbo on it.

I answered this in my response to the thread that asked why people don't port 6 port engines.

i saw. thanks

Easy, he wants to hear from people who've done it before apparently :) ;)

Here's A 6 Port Bastard Port

I have!

wow lol is that yours?

I use to run a street ported 6 port setup, but I kept the divider intact. It had much better top-end than my current street ported 4 port. Both are N/A setups.
