fitted my viper c.a.f. today, few questions

[ant]

first, i took all this out

[pic at bottom] i'm guessing thats right? acoustic valve and gubbins?

 

[ant]

then i was left with 2 leads. the black one i blocked with a screw.

whats the other electrical one with the green stripe? hoping i dont need it!

 

[ant]

lastly, there was room to fit the "trumpet" in the fog light which seems the best place.
i tried but how the hell do you fix it to the fog light surround?

 

[ant]

anyone?

 

[Maz]

Drop Fred a pm mate .. he should be able to help ??

Maz

 

[Fred@BTM]

you want the trumpet external so you can see it??

 

[ant]

i can easy get the c.a.f. down to the fog light.

took the fog light out and the plastic surround but couldnt figure out
a way of fixing the bell/trumpet to it???

 

[ben_p]

daze, drill two holes in the back on the trumpit then cable tie it through the screw holes on the surround and pull it back into the surround

 

[ant]

there are no screw holes on the surround. it just clips into the bumper

Whats that thing for anywayz?

 

[ant]

what thing? the valve?

no idea - cars working just fine without it!

 

[portal172]

DOn't need a trumpet, just run a flex hose from the foglight (take foglight out) and run it up to the filter.

hey presto.


and cover the electrical wire that isn't being used with tape.

 

[Maz]

I don't have a donkey d1ck on mine either but it does need to go back on when the warmer weather is here ..

Hope you get it sorted mate ... pics when complete ???

donkey dick??

the acoustic valve is supposed to open up at certain revs supplying air to the filter - it stays closed at lower revs to give better torque apparently - I dont understand the principal though but makes sense to me removing it

The long thing that goes from the botton of the viper ...

yeah thought of that but it looks much better with the trumpet end sat there

i'll give one of the fabricators at work, he'll knock something up!

of course you'll see it in the flesh no doubt!

Daze, what did you have to do to remove that accoustic valve thing anyway? When fitting my viper it looked like I had to remove the front bumper or something to get to it!

I think it has something to do with the inlet/hose lengths at different engine speeds

Remember to plug the hose up to this valve neat the throttle body.

remove nearside front wheel, then remove the arch liner and you see it.

one bolt to undo to get it off [the horn also comes off but just re-attach it]


be carefull with the plastic plugs that hold the arch liner in, i broke them pulling them out

 

[ant]

Remember to plug the hose up to this valve near the throttle body.

is that important? i've plugged it up but not near the t/b.

 

[Mr Melon]

Nice one, sounds better than taking front bumper off! Cheers

 

[nelson182]

Reading through this, I assume removing the acoustic valve altogether only affects torque at low revs? Im suprised Renault even put this valve in. Very advanced!!!

 

[ant]

i didnt notice any difference tbh mate. If you're in the right gear it pulls like a mofo!
