Roto-fab CAI dyno results

[axis]

That insert looks sweet. Much less of an angle which i'm sure helps smooth the flow out even more. Like the old addage says, if you're not breaking stuff, you're not making enough power. Since you're getting knock, you're apparently flowing more air. Are you sure the gains aren't weather related? Good to see companies use information to better their products instead of resting on their laurels.

We thought the entry would make a little more difference than it did. I agree- the knock is probably from the car leaning out with the additional air flow. It's important to note that after a good drive/learn the knock went down and the power went up. It takes a little time for the engine management system to adjust to the additional air.
The testing on this thread has taken place in the last 10 days. In the first dyno session we started with the Roto-fab, switched to the stock, back to Roto-fab, etc. Ambient temps for both intakes were about the same as we switched back and forth throughout the day. In the second day of testing we went from the stock to the Roto-fab since the car had a stock intake on it already. In the latter test, ambient was appr. 6 degrees higher as our intake went on later in the morning as it was warming up.

Will the insert be available at some point?

While the results don't look massive when you say it as a 2hp gain, you're talking about a CAI that gives you around a 10-15hp gain, so you're actually making your product ~15% better.

Yeah! Let us know about if you can refine that knock out and will make the plug availiable as a retrofit!

I have until next May till the snow melts and I can drive again, so I have nothing but time!

I'm very satisfied with my roto-fab. Well done guys.

We are making some minor changes to the housing itself, but we don't plan on offering a plug to retrofit. It was strictly a test piece to see if we wanted to make a design change.
Our dyno testing showed knock on the initial runs...even with our test plug. That's why we did the drive/learn on the dyno. Once the system adjusted to the differences the knock #s went down and the power #s up.

3M Clear Bra

Stang Killer,
I am very interested in the Clear Bra. I suppose photos wouldn't help (invisible), but what can you tell me about the fit, looks and install?

Will the updated housing be available as a seperate piece so we can upgrade from the existing one? Thanks!

Patrick,
Although we did make minor changes, I wouldn't consider the changes to be enough to warrant replacing your existing piece. We didn't make a drastic change-just a slight increase of the radius and a little smoother transition. The test plug was going overboard the other way. When testing, it's sometimes best to make a more drastic change in a given direction because it becomes easier to test the concept and recognize the differences between the original and the prototype.

I have a question on the Roto-Fab unit and I think this was answered once before but I can't find it.

I know your system comes with an oiled filter but you also offer a dry filter. I've heard where some people say the oiled filter can mess up the MAF (?) or something like that. Have you seen this issue with your unit on cars over the long term. Is it better to go with the dry filter? Are they any performance gains one way or the other? If I went with a dry filter, how long do they typically last before needing to be replaced (I know different driving conditions and different parts of the US make a difference on longevity)?

Thanks for the response, glad to see your dedication to making your products better and I am very pleaseed with mine and proudly show it off every chance I get.

Good questions caverman. Dry vs wet...I was going to ask those exact same questions.

Victory Reds must think alike!
