What would be the consequences?

Just curious

 

The computer would not be able to get the correct air flow to make the perfect mixture. To rich or to lean which neither is good.

 

I'm not sure there is a difference between the two.

 

The v6 looks very similar but it has smaller diameter than the v8, it won't mate up with your intake properly, quick indication that you're doing something you shouldn't be doing.

 

Weird. When I was getting my car dyno tuned by Ed Wright he yelled at me for having a ported MAF. He had MAF ends from a Blazer which I used on my car so it could be tuned properly. I'm just making a guess at this since the ends worked I figured the sensor would be the same and use the same resistors.

 

The 4.3 and 5.7 MAF's may be closer to each other than a 3.8 and 5.7 maf

PS, my car is back up and running foo... test drive tonight. wheee!

 

why would you do this?

 

I'm almost positive they are different diameters. Aside from the obvious of fabricating a way to make it mate correctly to the rest of the intake tract, you are then burdened with having to have it tuned correctly for the V8 application, which I am not sure if it works or if it has been done before. Long story short, considering what a LT1 MAF goes for on the used, and even the brand new markets, I am not sure why you would go this route?

 

I race in a class where my LT1 is restricted from the stock TB size to 33mm. It's done so to even out the power between the other platforms allowed in the class.

I cannot do any tuning to the computer. Before someone says "How will any one know?" ... I will know. I'm not one to cheat to win.

The motor runs extremely rich, I can only assume, because of the restriction. If a V6 MAF would cause an otherwise normal motor to run lean, this might be a solution to use.

Also, by rule, I cannot alter the MAF in any way. Virgin, fully screened, used MAFs are extremely rare.

 

if you cant tune the computer maybe you can unplug an injector or 2, help decrease the amount of fuel getting dumped in.

 

I really hope this is a joke.

 

What if the maf gets dirty from your overly oiled K&N air filter? You could always put it on backwards. I forgot if that leans it out or richens it up though. And I'm assuming you cant run an adjustable fpr or smaller injectors?

 

Or maybe I could just not put as much fuel in the tank ...

Backwards .... hmmm.

FPR is OK and weren't 93 injectors smaller than 94-97?

So lower the FP? 10 psi?

 

Yeah 93's are 22lb vs 24 for the later years. I'de play around with it on the dyno to check the a/f or if you have a wideband thats better. With an un-tuned pcm the computer will re-learn and richen back up when you lower the fuel pressure so you would have to re-set the pcm before each race.

 

You're assuming incorrectly. The MAF doesn't care how restrictive your intake tract is, it measures mass air flow regardless. You have a problem somewhere else.
