Is the bigger intake really necessary for the c32
So im wondering, does the sl55 intake kit really make a big difference in the c32s as far as performance. I cant see it doing much as much performance wise. Not only that, but i hear that people who have dynoed their car after they installed the intake, had LESS low end power on their car, but i think they also said it increased top end power slightly thought, so it evens out. I dont have the sl55 kit on my c32 yet, i just got KN drop ins. and before i install the pulley kit and tune, i just wanted to hear some opinions on this matter. So right now im just debating if i should get the pulleys installed and tuned with stock intake, just KN filters, or if i should get the sl55 intake first.

think of it this way more air more power. now... heres the latest flow chart # from needswings. the srt-6 has the exact same intake you have on your c32. the numbers from the oem box to the sl55 intakes are huge. then to the dual cai is massive from stock. this will help make more power

I understand where youre coming from 320dreamer. I just think that the sl55 may be a litttle TOO big for the our C32s considering its for a v8, not v6. Just dont see why the low end power loss though after installing the bigger intake.

and regarding V6 vs V8, this a supercharged V6, so it actually requires MORE air than a regular V6....can't compare a F/I 6 to a N/A 8

i would upgrade, it provides a noticable amount of upper end power compared to stock or even a code3 setup. We have enough low end tq already, i think some times we have too much low end tq.

I remember when we were dyno tuning my car I wasn't getting great numbers, so for shizts they put a 3" open tube off my intake (no air boxes or anything, so no restictions at all). I gained 25+ horse with it wide open...that was vs. a stock air intake setup.
I have the intake from an E55 now (basically same as SL55) with K&Ns...I did gain 9 rwhp or so from it peak, never really checked arcoss other areas of the band.
That said I'm still banging my head to add more air flow somehow. Right now I have it in my head to maybe open up the ram air ducts in front of car so the ports are larger to pull in more air into 3.5-4in tubes to my E55 air boxes. I'm thinking I could mock something up with fiberglass up front into the larger tubes (which I beleive now are 3")...hell I dont know

the issue you have with the e55 boxes is the drastic change of direction thru the filters. this causes a large amount of turbulance in the flow and slows down the air. if you look at the needswings setup it flows from the filters in front in a gentle curve all the way to the throttle body. this allows the a larger amount of air to reach the t/b without disturbance. i know the setup wont work with your front engine area but maybe a canister filter just behind the rad and the same curves to the throttle body with a 55 splitter can bring up the airflow #

It is, your thinking was correct. I'm not sure what jturkel meant when he said N/A V8.
In any event, the SL55 intake is supposed to be a nice upgrade from the stock C32 intake, and keeps a somewhat stockish appearance in the engine bay. Further gains can be had by going to a tube-style intake, if it's designed/engineered and implemented well.

Yeah i noticed that power difference too. I just dont see the SL55 intake as an upgrade. I guess im just used to seeing the aftermarket cone or cylinder looking filters as an actual performance part, but with our cars its hard to fit them into our engine bay without letting it use the hot air coming from the motor. Oh and i thought the SL55 was a v8 supercharged motor lol ![smash](https://mbworld.org/forums/images/smilies/smashfreak.gif)

and yah, it is interesting that you would put the intake from a 55 onto the 32, but IIRC, the 55 also has the same injectors and TB (especially IIRC on that last one, i really don't recollect for sure....if it isn't the same, it is within 2 mm)

it's more than the filters that are the problem
there is no clearance by the firewall to allow a 3" (IIRC) pipe to attach to the TB. you'd have to cut a bit back there for fitment.
our radiator supports are not the same. the srt6 guys have/can make larger inlets by messing around in there allowing for greater flow
they just have an overall larger engine bay which makes things easier....as seen with being able to have a much larger heat exchanger and the larger intake manis......
... i've spoken with rob about this a yr or so ago and he was trying for a while to make a better intake for the c32......he was testing but either he isn't done or decided not to sell it. i don't know the specifics, but i do know that rob won't sell a product if he can't back it up with top notch performance.

i have a set of the tvt tubes and a 55 splitter if anyone is looking to make a custom setup. was going to use it on my 32 but got a sweet deal on a needswings dual cai and its the highest flowing setup out there so i grabbed it. 150$ if anybody wants the other stuff

I love the low end torque on our cars
but it seems like the sl55 intake does improve on top end and takes off a little low end, which i can deal with. It did perform better on the 1/4 mile. Did you buy the sl55 intake kit or you just bought the parts (y splitter, air boxes and hoses)? i was going to buy the parts from parts.com for $320 plus shipping, and was wondering if i needed to get the air filters as well, i have the KN dropins for our stock setup. do i need to get the bigger ones for the sl55 setup? and also will the bigger hoses fit into the back of the ram air inlets in the front of our cars?
When you get it all figured out, let me know bro. I just know theres got to be something better than the sl55 for the c32s, but for now, the sl55 is gonna have to do.
I know a few people have done their own custom intakes, someone had a y splitter right into 2 cone filters, but the problem was the hot air that it was sucking up, so that was the main problem.
