    Whipple Cobrajet MAF Data?

    Looking if anyone has MAF data for a cobrajet MAF housing, believe it's about 140MM.

    Bump.

    I noticed that the 2013-2014 super cobrajet also had the 2.9L whipple option, but too hard to tell if the intake tube and MAF are the same. I have a 2013 cobrajet file from the repository, scared to use it.

    I think the old ones were 123s so I would start with that plus about 30%. Just take it easy building much load until you see how close it is or get it close. You'll get an idea of the correction that needs applied if you get it close enough to get some data and apply that error at higher airflow than you have yet to reach.

    Ok, I will probably start with the Whipple 123MM stock data and add to that. The range defined in the Whipple calibration is probably more in the range of what I need.

    Yes. It's scaled better for added resolution in boost.

    It is not. 16 had the slot MAF as part of the CAI. 13-14 used the aluminum 140mm MAF you have pictured.

    Sorry you are confusing me. The link I posted was to the 2016 CJ cold air, which has a slot style MAF, it is also described to be about 140MM.

    I have no info on the 2013-2014, and didn't post anything about it except I have a tune saved from the repository. ridenrunwv posted that he believes the 2013-2014 was 123MM housing.

    Maybe it was 140. I don't follow the factory race car setups very closely. If you've got the setup on car give it a try and you'll know quickly with a log what changes to make or what size it is compared to the Cobra Jet file you have.

    Thanks guys, not on the car yet just planning ahead. Currently running the GT350 setup just to have some fun and continue to learn more on the tuning. Whipple is on the shelf waiting install, I am considering upgrading the open air type of intake tube it came with to the cobrajet but was concerned for lack of data.
