RPM 5" Intake for ZL1 Camaro's (Now in Stock!)

[Frans96ss]

We have had some amazing feedback and independent testing by a few different shops who were able to make some great power with our 5" intakes. Since the initial release we have been hard at work keeping up with the demand and initial orders. Thank you everyone for your patience and orders. With that said, We are happy to say we are all caught up and now have plenty in stock!



Our 5" intakes are a must on ported blowers and ported snouts allowing optimum air flow to the supercharger. The filter sits right behind the factory brake duct for increased airflow to the high flow K&N filter. Not only have we seen power increase over 4.5" intakes, but our RPM 5" intake is the only 5" intake on the market that allows you to customize your options from PCV fittings to Meth & IAT bungs.

- Black Wrinkle finish

- MAF Flange

- High Flow Green Filter

- High temp Silicone Hose

- 5" Hose Clamps

100% Made in the USA (In house at RPM)

(AIT & Meth Bungs are optional add ons)

So there is no insulated box as in other manufacturer's systems to keep this from being a hai (hot air intake)? That sc throws a lot of heat and raises the underhood temp considerably.

There is not, nor a need for one considering where its pulling in air from. The filter sits much further away from the engine and behind the fog light location and gets constant fresh air.

If the filter was sitting behind the headlight and above the header like most I could see a use for one.

I know this is the wrong Forum, but Fran will you guys be building a 5" intake for the 2017 ZL1.

No problem,

Yes we will be, we need to get one in to do some testing.

If you want to schedule for one and can drop your car off we will give you a VERY good deal on making one for the 6th gen and installing and tuning it on your car.

I will call the shop today or Monday. You guys just did my buddy Bernie's ProCharged C7 Z06 and that thing came out pretty awesome.

It would be interesting to see if there was a way to measure the temp of the ambient air to that coming to the MAF vs at the filter.

As with anything that heats, it expands and the metal 5 inch pipe is being heated by the engine compartment.

Is this negated by the Fresh air/cold air and therefore a push?
The colder air is supposed to be smaller and therefore increases the amount Oxygen per square inch and this increases HP. (i think this is how it works)
Would cooling the long pipe help this? Or by having the pipe near the "fresh air flow" do this?

Also, looking at the metal pipe in comparison to Carbon Fiber, depending upon the MFG process, the inside of the pipes should be as smooth as possible. (In your product, the crinkle look is only cosmetic and not the same way on the inside, correct?) Is the inside of the metal tube as smooth as or smoother than the porting that is recommended on your web site?

Does the smoother airflow going into the intake/MAF effect the tuning more or is this negated after it hits the MAF going into the intake and therefore the recommended porting to increase air flow?

And last, one being lighter, but the heat retention and therefore radiation to the air flowing through it, which one would do the job better? CF or Metal?(Cost factors aside)


Just questions after seeing the video and the quote about heat.

PEACE

No the wrinkle finish is not on the inside there would be no reason to do that.



Also if you look at the pictures the filter location isn't even in the engine bay so it is not exposed to the hot air that most are. It is constantly getting fresh cold denser air (A lot of it due to the intake diameter) Also the MAF is on a dead straight making it easier to tune and not an issue we designed it that way for that exact reason.

Also to make this intake out of Carbon Fiber would be insane $$ wise and CF still gets hot so not really worth the increase cost for a minnor change in actual material temp. Not even worth discussing or entertaining.

The fact that it is getting cold fresh dense air (especially while driving) completely negates the fact that the intake material gets (hot) it is not enough time or difference to heat up the incoming air to matter.

Here is some basic CAI info

Cold air intakes move the air filter outside of the engine compartment so that cooler air can be sucked into the engine for combustion. Cooler air brings more oxygen (denser air) into the combustion chamber and that means more power. The filters are usually moved to the upper wheel well area or near a fender where there is more access to free flowing, cooler air and less hot air from the engine.

Not only does a cold air intake reduce the air temperature, but it also increases airflow. Aftermarket intakes remove the need for a box surrounding the air filter and instead use large diameter intake tubes that are smoother, have less bends and are often wider than the original factory ones. Removing the air box and using smoother tubes gives the engine uninterrupted airflow.

And don't forget one other product: silicone (regularly used for intake).

[Frans96ss]

Picture so you guys can see where and how the filter sits.

Does anyone know what's the size of the Roto-Fab cold air for the Gen 5 ZL1's? Are they not 5 inch as well?

[Can'tHave2MuchHP]

I believe they're 4". Definitely not 4.5" or 5".

[Dega Man]

Roto Fab O.D. measures about 4 1/4"

[mred2nice]

Are there larger throttle bodies that take a 5inch connection pt? I am guessing that the silicone elbow has a reducer built in. Can anyone talk about the effects of reducing the tube size id?

Thanks Ed
