MAF Location

Is there a "rule of thumb" for the location of the Mass Air Flow sensor? How far or close should it be to the throttle body? Does it matter if it is located next to a bend in the inlet tube?
Thank you, Gil

I believe it's a case of straighter is better with minimal inside diameter change. My setup has a 90 bend to stay under the stock hood. Still makes good power with proper fueling.

I can see that you don't have a power steering pump in the F body location which gives you more room to put the intake on the left side.   I have put the intake towards the left and snaked it around the hood latch and the head lamp mechanism.  The only place to put the MAF was at the end of the intake pipe just before the air filter.  I have put a few miles on the car now and it seems to run ok.  I have not looked at fuel trims yet or attempted any tuning.  I just hope that the setup I have isn't going to cause problems. When I posted the picture, it cropped out the MAF and air filter. They are next to the coolant reservoir.

Ah yes, old photo. I've since added a ps pump but was able to keep the intake mostly the same. But I don't have the stock hood latch nor the headlight mechanism. So yes, much more room.

And I see what you're asking about the cone air filter going right onto the MAF. I can't tell you how much, but I do think that'll affect the air metering due to lack of straightness of the air. Also, is that a cleanable / oil-able filter? Be really careful no oil is lose on that filter and gets sucked onto the elements of the MAF. Could be easy to happen with it that close and it's a pretty common complaint to K&N that the owner ruined his MAF when he cleaned his filter.

Also, can you get your brake master more level? Having it tilted that much could be problematic with getting air bubbles into the master and/or popping the low fluid light on your dash.

Other than that, it's looking good under that hood.

Yes the air filter is a K&N filter that requires oiling. I have used many of them in the past and I know it doesn't take that much oil to do the job. I wondered about the master cylinder being level. I'm not sure why but everything in the driver's side rear corner of the engine is really close. If I try to move the entire hydro boost unit to level the master cylinder, it will hit the valve cover. Is it possible to slot the master cylinder mounting holes to rotate it or would you be concerned about the strength of the casting? I wouldn't want the master cylinder to break off the booster at the wrong time. As it is installed now, the brake fluid is above the minimum line in the right rear corner of the reservoir. It may cause problems with leakage from the cap at the track when things expand from the heat.
