im new to cossies so help me out

my 2wd saph backfires & splutters at high revs so whats the crack there as its hampering its performance a bit & the boost is peeking at around 14psi

it has green injectors, bajoo chip, rs 500 intercooler, collins actuater, 3 bar map sensor, k&n & stainless exhaust & maybe a hybrid turbo but im not sure, has dyno graphs for 340bhp

im thinking maybe a set up as it sat for nearly 8 months plus, i havent changed the plugs & leads yet either

cheers

Plugs would be a good start,if it was me i'd change fluids cam belt etc too .

rapidcossie

change everything you can afford to as it will all need doing at somepoint!

tabetha

Good advice, just change the usuall suspects, ie plugs, make sure it has decent leads, inspect the insulation on the phase sensor, change the CTS, get it set up for peace of mind.
Do the FUEL FILTER as well, although this small item will not give the misfire, it is so often neglected, but is so easy to do, ok then it can be a royal pain in the rear with brackets breaking etc but is important!!

ok i'll get strait on to that today, what sort of boost should a car of this spec be running would you say??

around 20-22 boost would be fine boss

tabetha

I would set it very low, and take it to a rolling road for a fuelling check etc where they can adjust it to what chip supplier says is correct for the chip.
On this power usually around 24/26psi.

If dark greens id say 26 psi although i ran mine on 28 lol.

Thats fine mid range, but high up you're likely to blow it up

And seeing as this guys just bought a Cossie, and will want as much power from it as possible, I'm sure he'll set it to 28psi and it'll be fine for a couple of weeks lol
