I have an 00 SS with a RA II hood with an air dam that goes directly into the front of the air box {I sold the factory SS hood}. I also have FTRA. I just read in another post that I cant have both. I read that I need to seal off the front of the air box. Can someone tell me which is better to have.

All this time and I did not even know that they were cancelling each other out.


Thanks,

 

If you can seal the hood to the airbox with no leaks, I would do that. Otherwise I would stick to the FTRA and seal the front of the air box off.

 

I'd use a lid and FTRA, atleast the hood will cool down the engine some.

Also did you see the lower SSRA for the FTRA, thats what I'm getting

 

Yes thats where I saw the post about sealing the front of the air box. I wonder how much I was loosing due to having it open. I will be sealing it up tomorrow.

 

Hmm, I guess i'll have to put this with the emphasis that if you stick with the lid, FTRA will be better as it will have a true Ram Air effect as speed increases and the hood will be for looks and cooling.
On the other hand, I have FIPK and I just got the ULTRA Z hood from SLP to give the FIPK direct fresh air injection. FIPK being and open element therefore gets more air than FTRA (Proven on a dyno in another post). I tossed the SS hood as u did (just for show).
So I guess its a matter of choice for style and performance.

 

Any links to this RAII hood you all are talking about

 

I run a WS6 hood and a Whisper Ram Air on my Formula with good results.
