Don't know where you got your info but I have seen numerous dyno sheets going from a normal CAI setup to a ram air setup and seen big gains.

 

Show me one! I've personally witnessed dynos of ws6 and regular lt1 t/a's with k&n and slp cai setups and there was ZERO gains. Do a quick search and you'll find tons of threads on this topic here and the rest of the Internet.

So prove me wrong.

 

There may be small gains but I have to agree with Dave 00. The CAIs have enough CFM to supply the engine on the dyno. The WS6 airbox gains are at speed, in the 1/4 mile, street races etc

 

This is what I run on mine...Its for an LS1 but easy enough to put on an LT1 car..

 

I have a painted Firehawk box, with K&N filter and all hoses, that I might be interested in selling. If you're interested PM me.

 

Here is what I did.

 

I built my own box. I entertained using the Volant air box for the LS1 cars, but still $250-$300...

 

So, it makes a difference in the real world, and (suppsoedly) not on a dyno, so it can't make much of a difference right? When I switched from a moroso cai to my ls1 ws6 base and lid set up, I noticed gains from the start, full throttle in 1st gear resulted in wheel spin at any time, any speed, any rpm. Shift to second with the cai I could get a revolution or two of spin, with the lid set-up, the first third of the gear. At the track I picked up 3mph and 2 tenths. Car had a lot more in it, but I already had a hard time launching it, and the gains just maid it harder for me. My best time on street tires with it was a 13.5 @ 107 on a 2.2 short time. Ram air makes a difference everywhere, biggest reason is it's a straight shot to the throttle body, and a lot better air, (more of it, and a lot cooler). My manifold would also get slightly pressurized at speed(60+), and also IAT of ambiant or ambiant -1 or 2 degrees, and can out flow a cai

 

It cracks me up that people think a CAI flows just as good as a WS6 ram air hood and airbox.

 

So how much would it cost if I went the route of using the LS1 lid. And do the LT1 Airboxes come up on ebay often.

 

I know it flows better than a CAI, but the gains can be felt more so on the track. Im an advocate of the swap and have no doubt gains would show on the dyno too.

 

And you could easily go the LS1 lid route for under 100 bucks. A lower airbox should be around 20 or so, the lid should be around 50 and the coupler/air filter should round out the 100 bucks

 

You're not going to get any ram air from the lt1 hoods. The scoops are too far back and too low.

 

Nice pic man, but take a pic of the baffles in the hood and then you'll see the restrictions that make it equal to the CAI. Let me reiterate, I have the Ram Air setup (obviously) and love it, but I'm just stating the facts. Ram Air makes ZERO difference on the Dyno and maybe some real world difference but with variations in track temps, air quality and weather it is very hard to quantify.

 

my current ghetto setup - only because the WS6 box / LS1 lid setup wont fit under my stock hood. car runs great and I have yet to see temps rise above 165* even sitting in stopped traffic for over an hour... it is winter however



I have a LT1 airbox as well as a LS1 base with a SLP lid - once the local speed shop gets their dyno setup (expected first or second week of Jan), I plan to do a back-to-back-to-back comparison with two 4000cfm fans blowing. One aimed where the LT1 WS6 hood openings would be and the other under the bumper pointing at the air dam. I know this may not be completely accurate but since I have all three intakes in hand, I may as well use the one that gives the most hp/tq and sell the other

 

^^ thats just retarded in so many ways...put 20seconds on the clock and i'll tell you...(the current config)


lets see with mine "ls1 lid swap no baffles & aftermarket ramair hood" Datamaster confirms i get ambient to-1 degree IAT readings so if its 75 degree outside i get 75 degree air at TB ,quicker throttle response, Straightened air flow , denser o2 enriched intake charge , slight manifold pressure @ 70+mph

str8 air flow Ftw!

 

Thanks for the info and some of the pics! looks like some people need to research before they go and start taking stuff off and deleting stuff! As for the dyno sheets I can see where ram air would be wrong because you are not forcing the air in to it like it was designed for! I dont really want to fabricate something at time. My apartments like to bitch about me working on my car so I try to keep major mods or repairs to a minimum, until I can get it to a buddies house. Just trying to get input about performance difference on the street!!
