Wait4Me TB.....

So I installed the 4in TB & 4in new era intake. Throttle response is poor. Is this because I'm still on the stock tune or because the ecu needs a couple cycles to adjust to the new air flow ?

You need a wait4me tune.

I don't think it is the TB Raz.

I got the w4me 4" intake and got the same poor response. With mine I suspect it is because the filter is covering up or going down in the hole and that is where the good air is. The big filter pretty much plugs the hole and it is like the car is starving for air. I removed the 4" intake and put my modded box back in and the throttle response was awesome.

I will do some more playing around with it but I think the best intake design for this car is cutting the stock airbox and let it grab the downward air. Cones will try and grab it from the sides and there is not much breathing room.

I got some shop time tomorrow morning for the crank pulley and I will post a bunch of pictures. I am going to discuss my theory with the guy helping with with the crank and see what he thinks.

Maybe take off your air intake and put the stock box back in and see if the throttle response improves. That would isolate the problem.

A 360 degree filter is probably a better solution than a cone where the bottom is not allowing air.

Something like this:

i posted on your other thread but I could see what you're saying. The inlet for the air is way too small for a large intake filter

Let me know if you figure anything out but like I said removing the 4" air intake fixed my problem. It would be better if the filter allowed air flow from the bottom. The cone does nothing more than pull hot engine air. Even putting the entire filter in the hole there is not enough room to get good air flow going.
Well Raz I tried another filter with no success. It has to be the MAF but I made sure it was installed the same wy as stock.

You figured anything out?
Have you guys spoken to or pm'd jesse on this- i have one coming this week so i would like to hear his take on this- would think tune would be paramount here as well

I was using his tune with the testing I did.
MAF element placement is important. usually it needs to be in the back with the plug inlet facing exactly up and down. Also on the filter thing. You need to PRESS the filter down into the hole half way. You have to move the wires out of the way and then it will press right down into the hole. That way it will get the air it needs. Using the 360 air ones like you posted did not make any change in power. So i just used the k&n one as it is able to be replaced at any auto shop without waiting for weeks for a replacement should that be an issue in the future.

The power will be gained on the TOP end, wot with the 4 inch setup and any horsepower over 580.. Anything before that, a 4 inch setup is NOT needed. I tried to explain that to everyone previously, But bigger must always be better right??? :)

The only reason why im making them is because people keep asking for them. The car WILL learn the fueling and the sluggishness and fix it though, it just takes a while for it to store its different Coeficients...

^ I got it !! After looking in there the stock air flow is almost non existant. I pulled out the tube that runs air from the fog light to the caliper/rotor and now the V reallllly pulls. Even at low speeds where I would normally hit boost i'm going just as fast but without even tapping into the supercharger. Now the air flows right into the intake. And the whistle noise from the intake is loud now at every speed - even 4th gear on the highway. The reason the 4in wasn't doing anything was because it was just plain suffocated w/out extra air flow.

Is there now still enough air cooling going to the front driver side brake?

Yea it'll be fine. Unless you're heavily tracking your V it wont affect breaking performance. Remember that the "stock" opening for airflow will not be sufficinet for a " non-stock" intake system.

Dammit Raz now I gotta do it :p
^ trust me. The difference is instant. You just gotta wiggle the front of the air tube and twist it out. Best thing is that if I need to go back to stock i can just throw the oem airbox on and nobody will even see that the duct is still gone :D...I'll do a thread on it later when I get get the pics i took. I figured this out because coming from a jeep srt8 a huge mod was using flex tubing and literally connecting one of our brake ducts directly to the water drain duct on the oem air box. On average it bumped up 5-6hp just from that. It never caused any ill braking issues and you were guaranteed the coolest air possible. Now on the V you could also get even more hardcore and plug the hole that aims at the brake rotor and literally bloat the whole air intake with cool air but I didnt want too much debris getting sucked into the bay.

Well here are pictures of Raz's mod:

Stock:


Grab the end closest to the front bumper and give it a good yank up:

^^^ I wonder if Jesse did that when he designed his CAI kit? Sounds like the CAI requires a lot more air than the OEM system since I don't recall hearing that the OEM system was starved for air. Interesting indeed ... ?

I've got the Jesse's kit and will be installing it soon - have to visit the dealer tomorrow first, though.

Thanks for the pics CadV - that really helps!

No worries about water hitting the filter?
Look at the picture "Grab the end closest to the front bumper and give it a good yank up". The top part is where the filter would be and the bottom part is where the hole in the bumper would be. Pretty good distance.
I wouldn't worry about water hitting it because the top tip of the intake is just visible above the scoop line....



Here is my intake and tb...





The difference was large after taking out that duct scoop and has absolutely no difference in non-track braking ability. It is still slightly laggy at low rpm but I will give it a few days for the ecu to adjust. I'm more than sure it will pick it back up. If it doesn't I'll cap off the hole on the inner fender wall thats originally for the duct and that should help create some "oem" like pressurization of air. Like Rob mentioned, I also believe that this style of intake on this type of motor will literally suck up small animals if given the chance and needs the oppurtunity to get as much air as possible
