Facts: Go out in the cool of the morning and find a safe paved area to punch it. DIsconnect the inlet to the throttle body and leave it unconnected. Cost no money.

Punch it and see the power available. DO NOT GET TOO UP ON THE SOUND that is the siren song that will mess your mind.

NOte the power of the free intake. No cost.

Now reconnect the whole thing and buy what you will.

Data, see my extensive dyno runs of all the steps I did on the hunt for more power, need to go to search or dig thru the posts I have done especially on the intake. Or review my gallery photos to see the dyno sheets, etc etc.....

Weekend yeah, WOODY

 

Thanks Waldig, love facts and figures!! ill check out your posts, i usually do in fact =).. Glad to see some good insight

Kolme

 

We are all trying to get enough torque to do that to our wheels for real.....LOL the dual cai is the first step on your journey to get there....LOL

 

I currently have the single NW intakes.

Would my next best mod be a dual intake, tune or C3 pulley?

Thanks, guys.

 

i would suggest c3 then tune

 

I love those wheels!

I hope you're not using these tires, though:





Might cause highway hypnotism!

 

You won't see all of the benefit of the dual intake without a pulley. So I would go with the pulley first. If you're planning to do them all, then do the tune last.

 

Kolme, there aren't any real scientific comparisons between the intakes. No one has compared the NW CAI against the others on the same car, on the same dyno, on the same day.

That said, there are a lot of guys that race, and time slips can be adjusted for altitude and weather conditions. The SL55 intake guys run almost identical to the single NW guys (assuming no other mods or the same other mods) and even some of the home-grown designs. I remember trying to make the same decision you are making now. The numbers are so close between the SL55 and the single NW you can't hardly tell the difference. I went with the single NW because it seemed a better design to me, and I liked the look. (The dual wasn't available at the time)

The dual NW intake is a bit of a different animal. Even though Waldig (Woody) has posted data on the dual itake, it wasn't as scientific as I'd have liked to see - he basically plugged one end of the dual intake and tested again. I would have preferred he remove the dual and put it back to single CAI, but so be it. The result showed a significant increase in hp and torque in the lower revs compared to the single CAI. There was barely any improvement at the top of the power curve. So a dual intake is giving you more low end.

So your choice comes down to how thick is your wallet, what look do you want, and how easy of an install do you want? No matter which CAI you pick, you will get about 25 more peak hp, and that's a treat no matter how you do it.

 

I prefer the look of the SL55 intake, it looks stock, looks tough and its dual intakes. On the flip side the NW sounds amazing, you should youtube some srt6 vids or ask some guys here for their links
You can hear the supercharger whine with the NW intake and it sounds decent. Your going to be smiling no matter what intake you choose because the stock intake is very restrictive, both will net you good gains

 

well, I will just add this, and Tom knows I like to push the vert to the limit...I just upgraded from the single Needswings to the dual...mostly on a whim...not thinking there would be significant difference between the two. I just like the look, and I will post a picture soon, I promise. But, here goes for whats it's worth. My big butt dyno tells me a now have a breathing beast. I didn't hear that sucking sound at idle with the single. It sounds like a vacuum cleaner. Next, the butt dyno at the first stop light in Detroit, that I mashed the gas on, well, she broke lose without hesitation. This kind of made me feel pretty good, so I headed out on I-75 for a short romp...I feel there is a difference in the power on low end...didn't see much difference coming home on my 5 hr drive...with a few 130 bursts...big investment with low end gains over the single...its your choice...I will have #'s from US 41 Dragway in a few weeks...
Oh, and if you have the bucks to spend, I would buy the dual set up...over the single...but a single will do you just fine for the road...but when playing on the track, you want every 1/10 of a second you can get, and that costs $$$$$$

 

Since you already have an intake I would go with the pulley. And on the subject of intakes, While the numbers might be "close" between the SL55 and Single Needswings there has yet to be a single SL55 user that I know of to break into the 11's so take that lil tidbit as you will.

 

for those of you moving from a single to dual, whatcha doing with your single intake??

 

mine was traded back in...for credit toward the dual...
