Car Not Performing

[havoc_r33gtst]

my car is not running properly i think.. i only have minimal mods but it does not have much more than stock power wat could be wrong. it has a front mount, boost t 11pound , cat back 3inch zorst, heavy duty clutch. its only got 140atw.. could it be because of stock dump pipe???

[Pal]

do you have any type of piggy back computer or aftermarket computer. if not then you cant expect much. your afr's will be all over the place and (most probably rich) . once you get something like a SAFC2 (fuel only) or power fc (ignition and fuel)your power will go up to realistic levels.

[tridentt150v]

you will go up 20-40 rwkw with an ecu and those mods, you need to 'complete the chain'

[Ultimategtr]

Blaming the ecu is an easy thing to do. Could also be the dyno reading low. Post up a dyno sheet.

I wouldnt say anything is wrong.

Do the basics first, ie servicing(plugs/oil/timing/ecu reset, etc).

Mine pulled 175rwkw with only a catback and a pod and 12.5degrees and was only running 9psi.

[Trozzle]

yeah, of course ECU will make a difference, but I'm running 3.5" turbo back, FMIC, pod (which probably loses me power due to hot air intake), and is making 190kw at the wheels on 11psi

[Harey]

Its not the stock dump pipe. Maybe dodgy cat? Dyno would be helpful.

[lookingforboost]

could be anything happening as mentioned above, seems a little low though

i made 175RWKW with 3" catback pod filter and 9psi

then made 188.5RWKW with above and a 3" dump pipe added.

[havoc_r33gtst]

thanks guys i changed the dump pipe and im installing an eboost with a fcd within the next 3 weeks just need money for the tune.

even with the dump pipe changed i have noticed a big increase in spool and top end pull, so looking forward to the e boost

the cat is a xforce one so i think its decent

Please please do not install the FCD. Do your car a favour and at least try and get a Apexi SAFC II

[ARTZ]

whats your compression like....

you need to find the problem not buy more shit...you should be getting around 180kw...something is wrong..fix it then buy more shit...

I've got an SAFC II if you want one - sitting on bedroom shelf. I used it when I had similar mods to you - works well and gives other info like voltage levels, knock, etc.

[nicr4wks]

Similar mods to you, pulled 150rwkw, did a compression test, got sad

[Pattygtst]

Id be going a compression and leakdown test before anything else.

180rwkw is a base figure for thos mods.

Personally for mild mods like that i wouldnt bother with an aftermarket ecu. Your not really going to get much top end power. Fuel economy would be better though.

ive got 3inch turboback, profecb @ 11.5psi, fuelpump, fmic, pod, hiflowed injectors(unnecessary @ this stage), afc neo, made 197rwkw @ chasers then detuned to 193rwkw

tho it was just an afc it felt tad better to drive after tune

140 looks low friends auto made 150's with only pod and turboback @ stockboost

140 is way low..

mine made 186kw with dirty old apexi pod turboback and 11psi coutesy of a tap from bunnings...think it has a better fuel pump too..

you have a problem some where and an Eboost will not fix the problem.

indeed theres something wrong so as said above check first

[mad082]

may be something simple like the timing has been played with and is currently more retarded than it should be.

or it may be something serious, like low compression

That is a more polite way of putting it...

[havoc_r33gtst]

is there a way to raise compression if its down or is the car f***ed . could this be fixed if the mechanic i am going to checks it out ???? i bought it stock and then i got a boost tee installed the mech installed it and dynoed it he charged me 550 and it didnt seem to go much better even though boost was increased by 4 pound . since then i have changed mechanics but havent dyno tuned it ... should i ???
