LS1 MAF.......

[Guardsman]

Has anybody ever checked to see if the voltages that the L36 (3.8) MAF and LS1 MAF are the same or different? I'm wondering if we could use the LS1 MAF (it'd have to be mounted in front of the TB), and remove the stock MAF, because the LS1 MAF just has a little rod and a couple of wires, not the big chip that ours have (better airflow). The main question would be if they airflow voltage signals are the same or different.

no they aren't swappable, the 3.8s have a MAF/TB in one the LS1s have a TB and MAF as 2 seperate peices

www.ZZPerformance.com is coming out w/ a kit that allows us to use the LS1 Throttle body and maf. They are still working on it, but they say it's close to being finished. It will be good as a last resort mod, after you put on heads/cam, hot rockers, and ATI sc kit. The stock tb/maf is 6.5 cm. in diameter. this flows more than enough air into the engine to support all basic bolt-on's as well as heads/cam and hot rockers. Since Batman is still alpha testing the ATI kit, I cannot say if you will need a bigger tb/maf after that is thrown on one of our engines. The only thing i could see anyone getting out of this on a stock or bolt-on modded car is maybe better throttle response.

Guardsman - do you wonder if people get the real question... I would run this one past Magnus, from some posts a little while back, he sounded pretty knowledgeable about MAF specifics, frequency vs voltage, and exponential vs linear. He may know if the ranges are different.

If you are thinking of just taking out the MAF sensor, and leaving the existing TB, you will still have that big post in the middle of the TB, so I don't think you'll see any air flow gain unless you port the TB. The existing MAF sensor is fully enclosed in the post except for the 2 wires, so the sensor being in or out doesn't really affect the airflow through the TB.

the only problem there is, at least with the 99+, you get a electronic control throttle system, ,whereas the LS1 TB and i believe the GP TB's are cable control. there would be a lot more required tinkering, it's just not worth it. not to mention our intake manifold is only XX mm around, and our TB is giant as it is, bigger would result in loss of airflow velocity, thus loss in power
