exhaust

[grinder]

well im on a roll today so ...

when i look down the side of the engine to where the exhaust comes out - it comes out in TWO seperate pipes

is this a standard thing - cause when i look at the haynes manual it shows as an exhaust block attached to the engine

thanks

Stu,

Turbo engines will have one pipe out the back of the turbo.

Non-turbo may have the two pipes, depending on whether or not the exhuast is standard.

Is yours the non-turbo model? (no bonnet scoop).

[grinder]

mine is a Non Turbo and it has 2 large exhaust pipe coming out of the engine - i was wondering if this is correct !

( not sure if it has an aftermarket exhaust but i have a reciept for a Jan Speed exhaust )

[Glenn Butcher]

Yep - sounds like an aftermarket exhaust (nice!) the factory exhaust runs what they call a "Thermal Reactor" , or "Heat Exchanger"  big round cast iron thing (looks completely different to what you have, and what is used on the turbo cars).

[grinder]

cooooooooooooooooool !

will this give me any performance difference with that and the K&N panel filter

[Glenn Butcher]

Yes - it would be better than standard for sure.  I would only run Shell Optimax in it though (to make sure it is always running rich).

[grinder]

funny that you should mention that the car runs very rich ( you can smell the petrol )

i was gonna try and adjust the mixture/timing - maybe i should judst leave it ??

thanks

u can`t adjust mixture if u don`t have any piggyback or standalone ECU....

2 pipes from motor = header....on non turbo its way to get most power .....

[grinder]

do you know how much more power ??

or am i best getting it on a rolling road !

A good exhaust on a non-turbo rotary can give you up to 25hp extra.  So it would definitely be better than standard.  The best way would be on a dyno yes.
