Can i use a ls1 grantelli mass air flow on my lt1 and does anyone have one for sale? Thanks, Michael

 

First off, you don't want to use a Ganatelli MAF...trust me...

If it did fit, it wouldn't be correctly calibrated...

 

Anyone else know if a ls1 maf will work on a lt1? Shoebox, or injuneer?

 

Stock LT-1 MAF's flow enough air to support 450 RWHP. Unless a MAF is needed, it is the last part you want to start tinkering with. You'll never find one that is properly calibrated and you usaully end up with a good SOTP feel, but actually loose power across the board. I just did a test on this with a SLP maf. I lost 3 tenths and 3 mph by switching to the bigger MAF. I put the stocker back in and gained it all back. I wouldn't purchase a MAF unless it was going to be dyno tuned to my particular set-up.

 

I have one for sale. Have sent it back to the factory for recalibration to work with CAI system. If your intrested $250.
