I was interested in those little bumps on the exit side of the runners... wonder if they were intentional?

Do you mean the bumps where I just didn't finish it completely smooth?

Yea... they didn't seem to be there to support anything though, they could have been there to help the intake half release from the cast mold.... but, they might be there to promote a certain flow characteristic. But, looking at the rest of the intake, it's most likely a mistake leftover from when the mold was made. For those kinds of castings, they form a new sand mold for each casting. Looks like there might have been a problem with the mold. Take a look at your intake when you get it off. It might have that same feature.

In a bike engine, with individual carbs, each cylinder will still fuel for the amount of air it can pack into the cylinders. CV carbs are best at this because they work on vacuum in each intake so if one flows more air, it will still fuel more keeping the mixture right. In our DI engine, (or FI motorcycle engine) if one cylinder gets more air, the ECU is still only fueling for 1/6th of the total airflow so, that cylinder could be lean. Add turbulence in the intake tract to that, which can cause incomplete burning of the mixture, and you could run way lean and hurt stuff... mostly exhaust valves. Better a safe tune than broke from buying new parts.

Damn, one of the best V6 threads since the Vararam/thottlebody, We really have a lot of talent working on the 6'ers
Now if we could just get it blown let the 8's

Another thing to consider would be to port match especially if you are not doing the heads, By port matching (not gasket matching) you allow the intake to perform as it was engineered. Remember, that engineers develop and draft out parts, then they get adjusted to allow for tolerances in the casting/machining process. By doing the porting we get it back to the engineer's original design. Gasket matching on the other hand is greatly changing the shape and not improving flow at all sometimes then you are even worse off as you now have a lip sticking in the path of airflow... Im sure BSR has experience and I can only assume he know what he is doing and more kudos to you for even trying this out on your ownIt really would of been awesome tho if you had a dyno shop around to know exactly if you gained, same, or lost any. I am sending mine out next week to be ported so I should have some official before/after dyno numbers of what a tuned and ported IM will do to our cars. |

Me too prenger. I was actually going to wait for RX or even try to do it myself like BSR but I didn't want to leave any hp on the table or even end up losing more flow so I decided to spend my money right the first time. I don't want to hijack BSR's thread so I plan to start a new thread once I get a baseline dyno established and the porting halfway finished. I think I am done for this year once I finish with this and couple other things I am currently working on Unless somebody decide to give us early christmas gift lol cams maybe? |

OR, If you want your own thread that's fine too. Just know that you won't be stepping on my toes!

Is nice to know there's still cool folks on the forums. If you want you can pm me your ecm values after you install the IM and I can look over the changes (if there are any) for you. Im looking forward to your result.
