Going MSD intake manifold means you will need a tune or your going to lose so much low end TRQ you're going to cry. A CAI will benefit the MSD Airforce IM, but I am not sure which one. I am looking at a lot of data still trying to see which one I have truly provides more air which will benefit a MSD IM.

So far the Cold Air Inductions CAI has proven to be the best product out fo the ones I have tested thus far. I am test drop in filters, Roto-fab, AFE and GM's aftermarket system next.

Why does the hood have to be closed if a cold air filter is sealed in a box?

Mainly to get accurate heat soak data.

Cold air intakes that are open element or sealed by the closed hood will always perform better with the hood open, but it doesn't make for an accurate real-world test. You never drive with the hood open.

Intakes, like CAI's intake, are mostly sealed and pull air from the duct under the drivers side headlight. Hood open or closed they perform the same. So to do an accurate test the hood needs to be closed on all pulls especially if you are comparing open element to sealed box.

glad I haven't bought any CAI yet . Once GM releases theirs soon I would like test results, before pulling the trigger. Quick question Sledge - did you have Ported Throttle body and Throttle controller (some of your video you have them installed) during the dyno?

[Darth Martel]

I hit Mishimoto up in their own thread to see what their response is to your video. I feel like hitting them up for a refund since their claims are proving to be bogus.

This may be a dumb question as I don't have any experience with cold air intakes, but wouldn't go gains be minimal when the car is sitting still on a dyno vs going 100mph on a drag strip? The faster your moving the more air the engine would be getting. This is where the less restrictive intake would really make a difference in my opinion. Just thinking out loud. Again what the hell do I know.

The MSD intake isn't skewing the stock calibration. The loss of torque is actually less air entering the combustion chamber at the lower RPMs not an error in the tuning. The gains from a tune are the same delta in gains you would get with the stock intake in those lower regions. They come primarily from increased timing advance. The MSD intake won't screw with the fuel trims. At the higher RPMs the MAF is going to by default report more airflow so the AFR doesn't deviate much. The only area that would really need a tweak is the timing at the upper RPMs. It is a touch high for the MSD over 6000 RPMs but nothing the knock sensors can't compensate for if need be.

Now if you do the MSD and a CAI without recalibrating the MAF all bets are off on how safe it is until you actually look at the trims and AFR at WOT.

Does a tuner normally recalibrate the MAF?

[TSloper]

If the situation calls for it they absolutely should. It's easy.

Will the Roto-fab be tested with or without the add-ons? I'm guessing you'll be installing and testing the Roto-fab in a similar configuration to the other intakes?

Though it would be nice to see a second round of Roto-fab only tests showing comparable runs with oil vs dry and sound tube vs no tube (so 4 sets of pulls?). See if there is any benefit to different cost options are if they are purely preferential.

I will see if I can get both types of filters.

Just find a vendor who purchases the products from Rot-Fab over being a middle man only who drop ships. Roto-Fab can't take the blame from the Government as they are not carb legal / certified.

I tried to order one through them direct and they told me no as well. Its BS... I hate California. Can't wait to move to Texas on day.

As a native and former Californian, Nevada is not far so you can keep the benefits of being near AND we are FREE. No worries with ordering parts, or tuning our cars. Come on over!
