Just incase.. I know people don't go to the for sale thread often.

Probably will be deleted. But selling a RotoFab CaI

Why you selling it? Curious. PM if it's too secret!

[Ron_Robinson1]

This.

Reason for selling?

[Ron_Robinson1]

Long story short my car will be ran in stock trim this year at the track. Come Feb when I do my build (LTs, Cam, Heads, lower pulley, E85 conversion, and LT4 Nitrous Express w/ Meth lid) I will be going with a different CAI.

What did you not like about the Roto? What will you be going with?

Really doesn't make much sense...

Sure it does. He wants the highest performing CAI available which isn't the Roto Fab for all the mods he'll be doing. Right now with the current offerings it looks like Vengeance's CAI would fit best. But with no results from it yet perhaps he's being cautious and letting data come in before buying.

Opinion or fact?

Right. So RF isn't the best...but there are no results from the Vengeance...yet we have seen results from RF...but RF still isn't the best...but he'll probably go with Vengeance...despite no results...SMH.

He probably believes that because Vengeance says so, lol!!

There's only so much a bolt on is capable of without a tune. RF stayed in that sweet spot with no tune as many on here are very apprehensive about doing that.

There are others that have no issues with a tune and want the biggest gain possible for their dollar. Seems like that is where vengeance is playing. No interest in a no-tune option.

A tune does not change the flow characteristics of a tube. Nor does it magically make the engine suck in more air. The only reason you need a tune with these intakes is because the section where the MAF sensor is located has a larger diameter than the stock setup. Because of that, the ECU is not able to properly meter the air. So you need a tune to allow the air to be metered correctly. That is it. Everything else is the tune adding more timing or safely leaning out the AFR so it remains within acceptable range but gives a bit more power or even just adding more throttle opening. And that is where the vast majority of the hp or the feel of hp comes from. The intake gains are masked behind it. So with a tuned cai you might get 20 total hp...5 might be due to the extra flow from the tube and 15 might be from the actual tuning. With a non-tuned cai you might get 8 hp. So these guys with tuned a tuned setup will talk about how their system makes X amount yet nobody knows how much of it is attributable to the intake. In fact, it could be a completely trashy design that is robbing hp. But because the tune is adding hp, anything from the cai will be masked. THAT is why I hesitate to go with a tune required setup. Because their fail-safe is that the tune will add hp so they're safe and can report gains no matter what.

PMAS tried this. And a H2H of their system vs a JLT setup showed that there were no extra gains despite the extra 10mm diameter the PMAS had over the JLT. And the JLT, although being a tune required setup as well (due to a larger MAF section diameter over stock), never made more hp than the standard non-tune required intakes when a custom tune was introduced to them. Meaning that the tube itself is not better and has not been proven to be superior. The difference is coming from the tune. Plus they increase throttle speed in the tune which makes the car "feel" faster. These are all tricks. A properly developed non-tuned system WILL give you gains and WILL keep up with any of the tune required systems. People who say that "any intake without a tune is not doing anything" are just repeating what they read someone else say. I would love to see a H2H of both these intakes with and without a tune to show what is what.
