Idea for cold air intake

[Twisted Blade]

I have talked about this on another post but i would like some feed back from you guys.
I have been running some tests on the MAF and how far it needs to be from the TBI ( i have been told that it needs distance ) so far i have seen no problems with it mounted right on top of the TBI as it is the same size and the stock rubber will allow you to do so.
I have not had it on like that for too long as i do not have my cowl hood yet but it still fits with a low profile air filter.
The cowl induction will allow me to have cold air intake also and i think that is a good HP gain.
along with a TBI Blade mod i should see a good gain.
A cowl hood is not cheap so i would really like to know what you guys think about my idea.

I think it's an outstanding idea. Keep us posted on the results.

do you see any draw backs to the idea or maybe a way to improve on it, i am reluctant to spend the kind of $$$ on a cowl hood if i'm not sure how it's going to work.
I guess someone will have to try it before we know for sure but i would like to be sure it's not going to be a bad thing in the long run.
As i said in my last post, someone had told me that the MAF needs room before the TBI but when i tested it out for a short time (about 15 min or so) it did not show any bad signs at all.
do you think it may show something later down the road?

The biggest drawback I could see is if a backfire were to occur it would be more prone to failure.

The deal with it being further away is to enable a more accurate measurement of airflow. It is less prone to individual cyl. pulses the further away it is.

But I'd be damned if I'd let some theorist that's never tried it stop me from doing it. Been there, done that, liked the results.

Hehe, i haven't been running a maf at all for the last 4 months. Mine was bad, and am trying to get a new one on there, if it ever shows up. My truck has never run better without, awsome throttle response.

If you are a manual, it would be easy to switch to mafless operation all together. Auto's shift a little funny without.

EDIT: The main areas that you could see problems are at wot. The computer uses a hybred mode for fueling at part throttle. It uses speed density style, and uses the maf to calculate air flow. If it is going to run lean, or rich it will do it at full throttle. A scanner with the ability to log what the o2 sensors are seeing would be a good place to start checking for a lean condition(instead of the it felt ok test). A wideband o2 would be even better to check, although that get's a little on the pricy side of things.
