its a b.o.v
only turbo'ed cars have wastegates
you cant run on or i wouldent recomend running one because when u one an open ambient b.o.v all the air going is is controlled by the maf or afm w.e u wanna call it and u have the risk of the computer richening up the fuel too much and popping the motor you can run a diverter valve like the one sloveniaboy is selling.....

what does the diverter valve do...is it good to put on??
and ye i herd about running ro rich as well

Neil, you have a diverter valve right now, recirculates the boost to infront of the charger but behind the MAF. Don't put a BOV, it will run rich and cause all sorts of problems down the road. All for just a noise? Big deal, ricer :P

IMO, if you only got 300rwhp, dont even try to make any extra noises.
Once you are making 600+whp, than you can really play. But still, quieter = better.

Dont order kevlar clutch, talk to UUC they'll tell you with which one to go. I believe they actually still have clutch guide on their site somewhere. Read it.
Flywheel is good, but noisy.
Talk to VF if they offer traction control delete piping with their stage ii blower.
Due to aftercooler in my car, there was no room for it.
Larger throttle body is a waste IMO.

Dont go with headers/straight pipes for now. I suggest spending that money on cams.

Cams from AA? I believe they only make turbo cams. You dont want that.
Go with Schrick or Sunbelts. I'd go with Schrick though, proven and tested for many years

you can always use a bov if u go standalone using a MAP, seems a bit excessive for sound though:D *wiggle*

Axxe

Neil, M50 manifold is pointless for you if you are moving to stage II, which is a water to air intercooler built into the manifold (i'd imagine a badass high flow manifold).

Also, VAC makes cams for supercharged use, any opinion on those Vlad? Or do N/A cams work well on a centrifugal charger? Too much overlap is bad on a forced induction motor.

Yeah, especially when VF did such a nice job with the tuning for their kit.

From the guys at Bimmersport:

Dont act stupid *no-no*

Wait till you go stage 2 (unless you get into another acccident :P), I think you should worry about your walmart special tires rather than a "vrooom pshhhh"

So, Neil buddy let me ask you...since your going stage 2, what are you doing with the M50 manifold?? Since the cooling unit is going to be built into the manifold? If you go with all those things Neil, your s/c warranty voids and all that. Your software must be kept from VF (GIAC), which can't be possible if you add an M50 manifold.

AA headers from what bruce is mentioning is an E46 application, they remove the cats on the E46. If YOU were to go headers, go with supersprint.

P.S. Your wrong again buddy, 300rwhp is what your car puts STOCK with the s/c..with your added catback its not much but maybe 5-10rwhp is added.

My word of advice, is follow this list:

#1 - New tires
#2 - New clutch/flywheel
#3 - Replace front shocks
#4 - Work on the rest of the car (susp. bushings, sway bar kit, AA DSB,)
#5 - Now go stage 2

I would much rather just go FI after my swap, but if Im going to be hanging with E46 M3...I have to be able to beat them in all other aspects. Anyways, you havent even utilized the power you have already...master this then go stage 2. IMO you should have done this before even going stage 1, I dont need to bring up why..

Neil, change those NOW.

I was actually helping you out, you car MAY put more than the 300RWHP ADVERTISED by VF because you have a dinan cat back (yeilding more HP than stock). If you'd rather go by an average figure on a stock example,. rather than yours go ahead. Im just speaking from real experience not reading off a company's website. :rolleyes:

I know you meant for now, but you didnt even read my post. In order to have a new manifold work properly on a stock M3 or 328, you dont NEED software but it helps..in your case you need it.

Email VF and see if they make software for your car with cams, and manifold...you will have to get it especially if you do cams, and if I were you Id keep the s/c warranty because a rebuild costs a lot and ONLY vortech supplies the parts.

Dont call me an idiot, because Im the one who installed your kit which your still learning about (basics might I add). If someone posts their opinion and you dont like it, dont call em to delete it...its what happens when you ask questions, you get replies with opinions.

Oh yea, what cams are you getting? Your not gonna put the shocks? Come on man, this is pure JDM stylezzz!

Thats a SuperSequential Blow off Valve that the guy has on his G35.

And you can run a Blow off Valve on MAF cars as long as the MAF is a blow through setup and the BOV is before the MAF.

Even a CBV (Compressor Bypass Valve) which dumps the air into the intake before the compressor will make noise....

i was running 16psi on my turbo with the CBV and a cone filter setup and it sounded damn loud...

Jon, you dot have to get software for the M50 manifold.
Also installing M50 manifold wont void your warranty.
Even if something happens to his kit, its gonna happen to his blower or thermoplastic. VF will just replace thermoplastic, and blower will be sent to Vortech for a rebuilt. Unless he installs a smaller pulley that will overrev his blower, M50 manifold, cams, etc none of that crap will void the warranty.
Even if he decideds to get custom software, it wont void hardware's warranty.



AA headers from what bruce is mentioning is an E46 application, they remove the cats on the E46. If YOU were to go headers, go with supersprint.


AA has E36 headers. And forget supersprint. Get AA headers, they bolt right up to the stock cats, and then they'll bolt up to the AA track pipe if he decides to go with them. If he gets supersprint, then he'll have to custom fit it, and it gonna cost him, ask me how i know.

That mustang sounds awesome, you can really hear the gear noise in that compressor. Although I'll admit the Eurosport is nice an muted, you can only really hear the gear noise with the hood open.

john, stop ripping on neil's car. He may not be able to rebuild his own motor, but he does what 99% of the people on max dont do. Consistantly drop cold hard cash into his car.

having said that, neil i want your damn tires, stop storing them on concrete.

Was wittness to him racing a couple of bikes on the HWY on my way home one night, he won.... I FINNALY caught up and gave him a *th-up* and he returned it :D took me about 2-3 minutes to catch up tho LMAO so good!
