what a cnut theses are to fit, had to fook around loads but got there in the end. think ill put another mount in the center of the car just to add sone more support.

the drivesharft gaitor is far too close for my liking thou so ill need to sort that.
any suggestions?

its a fiesta btw

Rick

it's not too bad on an escort, never seen it on a fez though.

PT

got a 4" one on my series1

Stavros

You got a 4in system on your S1? Somehow I doubt that.

4in TAILPIPE, but id be suprised if the sys is even 3in, most aint on RSTs.

PT

yep meant tailpipe misread

mikee_rs

lol i was gonna say

Project ST

Christ, 3"?!

You must be pushing around 500BHP to need that kind of low backpressure.

Hope your turbo's oil seals are uprated to handle the pressure drop*

(*awaits flaming from people who actually know something about turbos... )

Project ST, i'd be looking for a 3" system from turbo back with around 250-280+bhp

Dont think their would be a problem with a 3" system, maybe on a std/worn turbo it might let out some oil but unsure tbh

i will be running a 3" system, dont think mine will be a off the shelf jobbie thou



its the snob in me, i dont do off the rack

vroooom ptssssh

Dont blame you at the price of a 3" 'goose

Dan

What bore is a 'goose? 3 inches? As thats what's on mine and it's getting offensive!

I'd heat wrap the pipe to restrict heat build-up on the underside.

Not seen one on a fiesta though.

scottiemous

Standard Mongoose is 2" or 2.5", can't remember exactly

but the 3" is a more expensive option and only really gets used on higher

powered cars.

Ginge !

ive got a 3ins goose,,,,,,,,,, the problem with them though its there silenced unlike the 2.5ins ones


i only got mine cause it fits the cossie downpipe as thats also 3ins


mine aint near my d/shaft though


as my goose in on the roof of the car and the d/shafts are in the bin

Stavros

Wont flame, but that is bollocks.

Even 3in is seriously restrictive at 500bhp.

IIRC its starts to get restrictive on a cossie at jus over 400.

In an ideal world on a turbo car you dont even want to see 1psi in the exhaust.

mikee_rs

hes talkin about the reply from u guys not flames from the exhaust

a standard mongoose exhaust has a 2.5 inch bore


mine is made by blueflame and is the same exhaust that the last owner of my engine had because he found a 2.5 inch too restrictive

mikee_rs

dont they do custom exhaust systems

mikee_rs

lol i think so.

basically i bought a zetec turbo off a bloke on fiestaturbo.com when he was breakin his car. i had a 2.5 inch mongoose on it but nowi have bought the exhaust he used to have on it cos the 2.5 was too restrictive

reality

3" is fine up to about 800hp.. if you have a shit design system, then sure it might be a restriction at 500hp

Badman38

iTrader: (2)

you sure!!

Fiecos Dan

Ok, 3" is fine for a down pipe upto 550+ bhp if well design'd. but that dont mean you wont get more BHP if a 3.5" is fitted.
And a 3" zorst after down pipe is good for at least 650 bhp is well designed again.


2.5" down pipe is fine for 350 bhp, and 2.5" exhaust is good for more,

I've seen a pulser run 400bhp on 2.5" mongoose, on good boost and didn't seem to be a problem, Also saw a mate's pulser get 296 bhp on a 2" system.
