LS7 MAF ?

Post by #802PalmBeach » Sat Jul 17, 2021 3:02 am

Few questions,

Will it work with my VCM OTR ?? very important

Does it even make a difference? Worth it?

I am aware that minor fabrication and tuning be required, and I'm fine with that. Just need to know if this should be on my future wish list at all.

you need a adapter tube to use the ls3/7 maf , also it will need to be tuned

that part I understand and is a non issue. more wondering if it's worth it and what are the gains ( AFTER TUNE)

Are you maxing out the MAF? If not then there is no reason to go larger. If you are maxing out the airflow then you will need to upgrade to the larger MAF (or rescale); otherwise there is no point. It is not a performance enhancement for more HP but rather to make sure the engine can properly measure the airflow.

Valid point I just thought the improved flow across a bigger one would result in performance gains even without maxing it out (?)
