Back when my car had a naturally aspirated 383, it made 452rwhp through the SS airbox.

I don't think it's that restrictive

I beg to differ, my 97 SLP ram air setup is not restrictive and flows just as good if not better than any aftermarket CAI.

I bet top fuelers don't even mess with air filters. Heck the engines are only meant for one pass....

slp doesn't count... we were talking stock... and by the way... do you have numbers to back this up for the ram air ONLY... or are you just speculating?




pro drags DO NOT use filters... i was just making an example...




i don't think ram air systems have a problem with rain...

I used to have the SLP CAI and now I have the SS hood with ram air...I didn't see a difference at all, but I also don't think I lost anything. Has nyone actually dynoed the same car once with the SS ran air and once with a CAI? That is the ONLY real way to tell, especially since every car responds different to mods...There is only like one extra bend in the SS setup so I don't see where there could be that much difference at all...

To answer your other question, I don't think there are any problems with the SS setup ingesting water or anything else...I have never had that problem, plus why would they continue to make it if it cause the car to ingest water?

when it comes to airflow... a 180* change is 2 turns.... it would be hard to explain this without being there in person to demonstrate the geometry...(sp?)


but the ss actually has 3 turns in the air intake

Ok,I'll bite. The Ram Air on the birds is probably a little better than the SS.We are talking small differences here.I believe the scam air is functional at higher speeds,80mph+.Other than that and the looks, it isnt worth fighting over.

Never dynoed with a stock setup. Dynoed 2 weekends ago and put down 297rwhp w/ 316ftlbs torque with an A/F of 13.3 all the way across up to the revlimiter.
my mods consisted of Hooker LT's, mufflex y, SLP 3 inch cat back(with cone of silenced) Granatelli Maf, SLP air temp sensor, 58mm Edlebrock TB, ported matched intake, Crane Goldseries RR's, LT4 valve springs, 160*thermo stat, TB bypass, airpump!, EGR!, SLP steel billet flywheel, Spec stage 3 clutch, 1le DS.
Now considering my numbers I don't think that an after market CAI would of effected the outcome of my numbers at all. A huge fan blowing in front of the car is not going to help that much either in simulating moving air. Point being that SLP ram air is a CAI, its serves the same pupose as any after market CAI, it pulls cooler air from the outside. Dyno numbers are not going to tell you which setup is better, simple fact is both the ram air setup and a after market CAI are non restrictive setups, each freeing up air flow into the intake.

12.8 is ideal, I am starving for fuel up top, gentleman that was running the dyno said if I could run a little richer up top I could of saw 300+ at the wheels, he also told me to remove my accessories belt to gain about 6 rwhp and .2 in the quarter...tempting...
and no there is no problem with water leakage what so ever, the hood is setup so water can't get in, just air...and its pretty tightly sealed...

Both systems are induction. As long as the engine gets all the air it needs then either system is sufficient.

There is no ramming. In the case of scoop vs CAI, the temperature of the air entering the TB is the important factor.

A CAI that hugs the radiator will be introducing warmer air whereas one that is isolated and insolated from underthehood temps is likely to provide more performance.

The serpentine route of the Ram air isn't necessarily a restriction as long as it is large enough to accommodate the needs of the engine at WOT.

Add a high peformance filter like K&N or Holley Powershot and you get more air quicker. Anything you can do to keep the air at least the same temp as the outside will probably help.jmho

You dont have to worry about water ingestion, there are drain holes in the air ducting...they are very small, but apparently they work.

Think of this whole Ram Air thing as 'ricer talk.' You can say I HAVE RAM AIR!! And everyone will think you have a bagillion(yes, thats a real number )horsepower. It SOUNDS COOL!! LOOKS COOL!! Isn't ANY better than ANY CAI kit. If you were going about 100mph, you'd get MAYBE 5, 6 more hp? It's not even worth the 700-800 bucks. Compared to the 200 or so for the CAI, CAI kits are the best 'bang for the buck'!
