Hey guys, i have a 89 Firebird Formula with the 305 tpi. I am running the stock air intake. i want to replace that part with this: http://www.hawksthirdgenparts.com/ca...icarsonly.aspx I want to make my Ram Air II hood some what usable. I know it wont be a completely "functional" ram air. but it is not as quite as restrictive as the stock one I have. so my question is that can i use this with my hood and make it work? and is there a possible way I can make a "homemade" version of this because $200+ is alot of money for a little box. And my last question is: How would i use the stock MAF sensor on this? I have searched alot on the boards but i cant find exactly what i am looking for, I already know there is a ram air tech page that is located here: http://www.thirdgen.org/ramair but that specific type is not what i am shooting for. dont wanna so i posted here. Thanks!

I honestly would start at the junkyard and look at many cars as possible for their air boxes and go from there. That way you know there is a specific air filter size and housing. and just go from there...

does any one know how to use the stock MAF with this type of TPI air box?

use a rubber adapter that take 4in to 3 in

attach your maf sensor and you will have to make a bracket to hold the mafs

make your box out of cardboard or poster paper

transfer the design to thin sheetmetal or fiberglass over your box

make sure that you get a filter that will fit in your design before you write it in stone

your stock intake should flow enough for a 305, if your planning on building it up, then thats a different story. Was your 305 stock or built up?

yes, my 305 is completely stock.

I have the total air-ram hood and air box on my 89 Formula, it fits with a couple thing needed. I had to grind allitle off one side of my MAS just so it would fit inside of the air box and cut alittle off the airbox. Took me 10 minutes. Also you have to extend the wires for the new location of the MAS. As far as someone saying you need a bracket to hold the MAS up, mine is tight enough that I didn't need to. If you go this route make sure you use something like silocone to seal your MAS to the airbox. You can also goto www.ramairhood.com and see picutres and they have the direction for the installation and also sell the air box too.

Your '89 intake ducts are not quite as bad as the earlier Firebird TPI intakes. If you still have the inside-out (garbage can) air cleaner, you can open the bottom for better inlet flow.

WOW thanks for the tremendous help! I will definatly send you a pm thanking you

Any idea where I can get this? I was thinking this would be a good place to smooth out the air flow into the engine on my TPI car. The stock corrugated rubber looks like it would disturb airflow too much.

I contacted www.eautotuning.com. They have them for $6 plus shipping. It's a company that sells a cold air kit for our cars but will sell just the coupler.
