its defiantly loud. But sometimes i feel its not loud enough

 

From what I have read the n1 is a noisy bastard. Dont know why your specifically concerned about noisy annoying exhaust though. The attention it attracts isn't usually the attention you want.

 

Yeah my motor dyne is just enough that i can shift at 2k and get past cops from a stop

 

After 1 week and about 35 miles the Injen SES Performance Exhaust sounds great. It's not as loud as I thought. the drone isn't bad at all.

 

I havent seen a single mention of the dual or single momentum (now Z1) exhausts. I dig the way they sound ( just not with their test/Y pipes, thats way to loud to daily).

 

Current mods are plenum spacer, port/polished lower plenum, ppe lth, xyz ypipe (no resonator), and a 3" jic ti midpipe.

I have a 3.5" intake and nwp throttle waiting to be installed.
My question is, how lean would I be running if installed ?
I'll be getting tuned within the next few weeks.

 

I have an Invidia N1 exhaust, Berk cats, Injen intake (3 inches in diameter, I believe), MD plenum spacer, and I installed the NWP throttle body last week with the spacer. It was idling a little high (1k at normal temperature) so I did the throttle relearn or whatever it's called and now it idles at 750. It runs fine for me but I'm not exactly sure how much different it'll be for you. Hope this gives you a perspective on it, I know there isn't much reviews/info on the TB.

 

Well I noticed that my 3.5" intake doesn't have the bottom nozzle that'll connect to the hose connecting to the valve cover. Is this an issue ?? Or can I just put a filter on the valve cover ?

 

Quick question, I have stillen HFC's from the previous owner and I installed my motordyne this weekend. The HFC's definitely makes it LOUD as if I'm running unresonated test pipes. Does the V2 actually quiet down after a while? Also at idle my car sounds like a cammed V8. lol. Don't get me wrong I love it but I'm getting a bit of drone under 2k.

 

No it wont

 

Perfect. Now I have a reason to buy ART pipes.

 

This thread is of great help for noobsters like me, I just want to say thank you !

 

So i don't want to start a new thread so i'm just going to ask here and accept all the backlash that comes with it. Yes i know that intakes will not add horsepower and are only there for the sound. So i was wondering if i just went to Auto zone and grabbed a 3" OD Spectre tube if i could replace the silencer section of my intake. I have an 05 intake system on my 04 G. There isn't any local Z tubes and the Spectre pipe is $40-$50 Cheaper.

 

A little late, I know. Thought you were procharged? Anyway, the right intake does absolutely make power all day long. 3.5-4'". Admin tuning, limp mode tuning or make your own like I did, just don't make it too long and don't add any bends in it other than the one you cannot get away from off the intake plenum or you will lose power. Ask me how I know.

 

How would a 4 inch intake pipe going into a 3 inch throttle body make any more power than a stock 3 inch intake?

 

Buddy, that's like asking how exactly is a rainbow made, or how exactly does the sunset or how does the posi-trac rear end on a plymouth work. It just does!
If this website would let me post my damn dyno chart, I'd show ya. I got 5tq and 8hp across the chart. HP peaks quicker, flattens out and doesn't fall off towards redline. I think the t.b. will get me the other 1/2 of the power I was looking to gain from this mod.
My question is, is Administration Tuning pulling one's leg when they say a NWP throttle body or a large bore t.b. will help a large diameter intake pipe make even more power? I've seen some say yay and others, nay. Think the nay's didn't have a large pipe but the yay's did?

 

Sooooo you got re tuned and made 8 hp more... Unless the dyno is from the same dyno same day, same temperature, and the only difference was you installed the intake I wouldn't say the intake was necessarily what gave you 8 hp.

A rainbow, a sunset, and a posi are all very explanatory, and I'm sure your extra 8 hp would be also.

 

I made the intake based upon admin tuning and limp mode tuning's design. Pretty simple and straight forward actually. I didn't like that limp mode did away with the positive crank case ventilation and their heat shield isn't up to par imo. Admin has no heat shield and I had research pointing to a 4" being more beneficial anyway, so I said f'it and made my own.
I made it, brought it to the shop I had been going to, he ran the dyno with the set-up I had which was a z-tube, k&n drop in, deleted baffles on the air box & open up the airbox as the oen air box just suffocates the engine. This intake made 8hp/5tq above and beyond my modified pos, which was a much better pos than the stock unit (FX35 awd). After the pull he measured the new pipe, swapped pipes which took 5 minutes (car still on mustang dyno) spent a little time adding fuel and one final run. Power holds till current redline of 6,900.
There's plenty of info on this, from z's to g's to maximas, hondas. And no, rainbows, sunsets and posi-trac are still mysteries.
Check this out. It's my tank. Page 3 maybe? https://www.infinitiscene.com/thread...-redux.230572/ Now that I've done you a solid, find me some proof that the NWP throttle body makes power above and beyond a 3.5-4" intake. You'll want the info for yourself anyway, assuming you go this route.

 

i was but sold it to rebuild my motor now i'm N/A until i can afford another F/I Setup.

 

So you made your own 4 inch intake. good on you for not throwing away 3-4 hundred bucks.

I've debated back and forth with both the dudes that made the admin and lmt pipes about it, they all say the same thing. The car needs to be tuned right for it to show gains.

My thought is that if its tuned right with a 4 inch intake or tuned right with a 3 inch intake (like injen, k&n, aem, etc) would their actually be a difference when you compare apples to apples. I mean the jwt pop charger claims it adds 6 hp with a adapter and a filter that cost $100.

As for the nwp throttle body, im pretty sure the creator of the lmt intake prefers the stock throttle body.

As for me, I could care less about an extra 10 hp, I don't race anyone, this is pretty much just a hobby car I drive once a week when its nice outside...
