Stock- SAE rwhp 320.6@4900rpms
SAE rwt 408.6@4000rpms
With Airaid-SAE rwhp 314.0@4800rpms
SAE rwt 408.1@3800rpms

Runs were made 15min apart, and in a closed 61 degree dyno room at Colvin Auto. in Austin Tx. Very nice set up. I was however very dissappointed in the Airaid air box. I thought there was supposed to be a 15 to 20hp increase. Has anyone done a before and after dyno besides me? And no I am not gonna do a search to find out so dont even go there. I will be e-mailing Roger Lemere on this to see if there was any guarentee. By the way, my dyno three weeks ago was a 327.5@4900rpms and 417.5@4000rpms with the airaid, but that was STANDARD not SAE and my numbers were identical today with my stock air box. Not happy with Mod. once again.

1st run with stock box, 2nd run with Airaid, and 15 min's apart. Right?
If so something is definitly wrong. Should have shown a little increase, not 20HP, but something. Did you let it run for a while before dyno testing? Was the memory cleared before 2nd run? and did someone check the Mass Air Sensor connections.

 

No I did not clear the Comp. I totally forgot to do that. I am sure that is the problem. Will that make a big difference? I didnt realize it was necessary for the airaid, just the chip. Details please.

 

That's interesting Andre. I ordered a downs filter today. When I install it should I disconnect the battery to remove the old memory immediately? I realized it will gradually change but this seems like a good idea to check on immediate results, like on a dyno? Hang in the CAKA. It's probably better than you think, just not as fast as mine.

Kinda like clearing your throat before tasting something, it gives the PCM a fresh start for what it's being feed. As I said before the filter won't make any big number changes by its self. It will help the chip improve because of the general settings in the chip and how more air effects thoes settings.

 

guys, you dont need to 'reset' the comp for just an airfilter change. The comp isnt seeing anything new, the airfilter is just (well suppose to) just let MORE air into the engine. With less restriction, more air can come in ='s more power. Has nothin' to do with the comp.

 

O.K. guys,

I think this S%%T about the standard airbox suxs, it’s well, totally incorrect. I have a huge K&N air filter and MAF and I lose 2 hp below 2k and make 2hp above it.

It make’s a cool sound but doe’s little to nothing, sorry Sal!

 

I agree with F1car.On a stock L the filter just doesnt do much, it actually hurt me. But the sound of the supercharger in the closed room was totally awesome. It screamed louder than I have ever heard one scream before. All 8 people in attendance were stoked and grinning ear to ear. I also left the two side shields off of the airaid so that made it even louder.Also, the techs that performed the dyno said the same thing Andre did. That I will reap the benifits of the filter when I get my chip done. Later!

 

Caka -

I totally agree on the benefits of the air filter upgrade. You will not realize much benefit unless you have a chip. I took my chip off and went to Ennis last night. There were two Lightnings with Sals filter and two with the stock setup. Virtually no difference in the ETs. I think I may have had the lowest ET by 1/10 second, but I attribute that to headers instead of the filter. Silver_2000 ran immediately behind me on our last run and his ET was .004 faster than mine and he was totally stock. I have Sal's filter and JBA headers. I think most folks on this board would agree that the filter & chip combination is a double whammy. The filter by itself is not even a 1/2 whammy.

 

Don't want to bust anybody's bubble, but when you change the amount of air the intake gets it is registered by the mass air sensor, and the temp of the air is also taken in by the comp. BUST All of which is accounted for in the fuel air ratio mixture by the comp. BUST Again DUH!

 

1badtk,
What are you trying to say??>????>?

 

I don't think the aftermarket air filters do anything but make noise. I think it's like loud exhast...just sounds faster. Since I've got one I'll just keep it. But I don't think it does any good. I also can't see it causing any harm.

Where did you take hotrodding 101? Engines are nothing but air pumps. More air in equals better performance. More air out generally equals more performance. These air filter kits, (airraid, downs, & sal's) definately allow more air in; however many believe that in order to take advantage of that you also need a chip. My after market filter is on order. Since I have driven 17K in my L, I think I will be able to tell if it makes any improvements. I'll let you know.

hey noelvm,

The point we're trying to make is that the stock airbox alone is enought! Maybe the air box, chip & exhause and more, well yes it's time to up grade the air box! But with out the aboved mods you'll find nada!

Been there done it!

 

Nevermind!
