schmidt bros dual exhaust and clutch any good???

[onlyblue4stroke]

like the sound but sound isnt everything anyone here of the way these to mods perform????????

 

[Jeremy]

I have a set on their way as well as their clutch kit and Air pods !!! I'll let you know when I put them on !!!

 

[onlyblue4stroke]

thtd be great cause iam really considern my only concern is if i buy the exhaust and the airpods i would have to buy the fuel regulator to prevent it from leaning out

 

[yamafarm]

I have one of chris's pipes. it woke my Phazer up big time. I found it to bee a little loud but it's a an early prototype so he is gonna rework it for me.
I used an Ulmer kit for my clutch and It works great!

 

[onlyblue4stroke]

well iam prety sure its a sealed deal but i just wanna know if its gonna lean out my sled ??

 

[Jeremy]

I will ask my boss what he thinks because he is a ticketed automotive tech. as well as a small engine tech. I'll let you know when I get home after work !!!

 

[onlyblue4stroke]

thtd be great ive gotten a few oppinions and talked to a friend of mine at the dealer and he said tht the computer will compenate for 10% but anymore than tht he said uwould probably hae to get the fuel regulator

 

[RedPhazer]

Probably wrong here, but I thought the fuel regulator leaned the mix out by reducing the PSI to the fuel injectors? If so, then you DO NOT need the regulator once you add a free flowing exhaust and the intake airpods... those mods will lean the mix out enough!

I got a chance to talk to Chris last night about his products, Chris is not just your Mass production type of guy, He takes alot of time profecting sound, and exceleration. I know he is really proud of his pipes. If I had a option of using a pipe for racing I would buy Chris's hands down.

Clutch kit Ulmer has that dialed in to perfection the guy is a big time Grass drager.

Hope this info helps

I might be wrong on this, Once you ad a pipe and intake and drive the sled for a few miles it self adjusts to a stock Air fuel ratio?? I might be wrong on this, but this is how I thought the system played out.
By tricking it with a lower PSI regulator your not allowing it to adjust it. It's like fixed??

 

[RedPhazer]

Good point, I never thought of that... I guess I would expect the ECU to compensate.

 

[Jeremy]

The ECU will compensate for those add-ons.

 

[Srxspec]

The ECU will NOT compensate for those modifications. It is not a closed loop system that can "learn" what you have done to your sled. It is a basic open loop system that is programmed to do what Yamaha has told it to do based off of intake temp, barometric pressure, etc.

 

[Jeremy]

What would you recomend in "onlyblue4stroke"'s case ??? Mine as well I guess. I have his duel pipes with only 3 of the 6 air pods installed as well as the clutch kit... Thanks in advance SRXspec.....

Makes sense because there is not a 02 sensor in the exhaust. You think if you have Fresh cold air flowing into the box it would sence that and add fuel?
