had my car mapped

[m0sch]

well after a custom map , my cars now making 252 bhp and 304 ft bs of torque on the k04 but iv got a problem with the intercooler its only a GRS one which is half the size of a forge so i need a bigger cooler to get more power and its twin pass so iv been told thats resricting me a good 30 bhp as the boost is peaking at 23 psi but dropping off to 14 at times so not good

just wanted a few recommendations on which new engine mounts i should look at getting and a good place to get some custom pipe work made up for the new intercooler ??

will be running it as pod this weekend at USC (i hope if nothing breaks before) so should be see to good what time i get as i got a 15.08 when it was on standard map with a dodgy MAF

also iv noticed iv used about half of my oil in the last 400 miles since having it mapped is this normal ? i know when you run more power you use more but it was near on full before it went for the map ( which went on the rollers and come off 8 and a half hours later and 3/4s of a tak lighter lol ) also my tappets are really loud when coming on to boost aswell :S

anyways soz about the essay and hope you can help me along from here

your oil consumption would worry me..
if it was done on the dyno, wonder how hot it got.
if its rattly now, your loosing oil pressure somehow, maybe strainer in oil pump pickup is getting blocked? or worst case for you, somethings failing.

some of the guys who started with the GRS one got the end tanks chopped and reverted to a single pass.. where it worked fine afterwards

 

[m0sch]

It's weird too I don't have any faults come up with the car it was fine on the dyno and for few days after then just got abit rattely iv not drove it properly since topping oil up to see if it's the tappets yet but iv got another problem now the car wouldn't start today then it started and sounded like it was blowing really bad then cut out so I left it at home today have to get it on a ramp later ! Would the grs still be too small tho as it's just as long but half the height of the forge ?

I don't know where to go to get it checked to see if it's the oil pump or what before USC which is Friday

 

[Cupra_Red]

I'd not drive it if it's used 2.5 liters of oil and is making a tappety sound, get a manual oil pressure gauge on it to see a true oil pressure reading, then I'd take sump off and change pump and strainer and hope that it's just that

 

[m0sch]

But as it didn't start I'm thinking it could be a piston ring or something ? Hope it's something simple spent 1500 in last month to get it ready for USC on Friday

 

[ashgtiturbo]

gutting mate! i'd take it to a garage and have them check the compression, sounds like it is burning oil so could be the rings or worse... chances are the tappets are not getting enough oil, is the pump the standard plastic or the metal impellor type?

 

[m0sch]

Standard plastic ! My mates skyline does a litre a week since having it mapped thought it could be to do with the set up and the fact it done 200 miles on the rollers then 100 miles to get it home plus 4 days of playing out in it so bout 500 miles since start of the mapping process but after it was mapped I was told everything is fine with it the temps are good and sounds in good condition too

 

[Cupra_Red]

If rings are gone or going you'd expect it to smoke (blue smoke)

To me tappets are tapping due to lack of oil or due to low oil pressure both are serious matters and should be donesooner than later.

As said in previous post put a manual oil pressure gauge on it and let us kno the results on idle and at 1500 revs and 3500 revs

 

[m0sch]

I was gonna take it to a garage it started first time then a minute later it just died ad won't start again and I don't have a manual oil press gauge so struggling abit to find the problem here

 

[m0sch]

hopefully its something simply like a coil ?

 

[Cupra_Red]

coil pack will not cause your car to use 2.5 liters of oil mate,

vag com will be your best bet to see why its cutting out after a few secands

but as for the oil loss you realy need to do it, halfrauds sell oil pressure gauges, it screws in on the front of the oil filter housing ( under inlet manifold, bit the oil filter is attatched to)


to see if its a coil if you aint got vag com is start the car, pull out one coil pack at a time if the coil is working the engine will run on three cylinders, a broken coil pack will make no difference to the way the engine runs when you pull it out, i seriously doubt its coil packs tho mate,

take your spark plugs out and see what they are like, maybe new plugs needed ?

 

[m0sch]

Yeah I'm gonna try thatlater with the coils mate also im thinking maybe fuel pump can't handle the pressure n broke or the relay gone Maybe ? Gonna check these later I put another half a litre in n it took me near maximum so when I do get it going I'll see what it's like I am trying to get a oil pressure gauge too I'll let u k ow if I find anything with coils or fuel pump later thanks for the help

 

[m0sch]

Also changed plugs 600 miles ago when changed the turbo mate

 

[Cupra_Red]

Also changed plugs 600 miles ago when changed the turbo mate

take plugs out and take a pic and post pic on here, can establish if car is running rich/lean by colour plugs have gone.

 

[m0sch]

Yeah I will well it as on the dyno Thursday and I was told everything is fine so hope it is running ok still ! Hope it's like te relay causing it to not start n just used slot of oil on the dyno lol

 

[m0sch]

played about with the relays then it started ok n it sounds like the tappet noise is a exhaust blow now im gonna put it on a ramp tomorrow and check the blow etc then see if it makes the noise still afterwards

 

[Cupra_Red]

Aw hope the tapping sound is a blow, but since u sed it used 2.5 liters of oil that would concern me

 

[m0sch]

Well it went from Half way between man n max to on min in about 600 miles including the map on the rollers so not quite a full 2 and half litres gone and I put half a litre back in now just below max

 

[m0sch]

changed the fuel pump relay but its still doing it sometimes it clicks sometims it dont so might be the live going to it either way im sure its an electrical problem but USC is tomorrow and no where can look at it today still no warning lights on but when it does start n drives sometimes it cuts out n flashes warning lights but they wont stay on

any common electrical faults on these cars ? cause its the wires around the fuse box that if you move it sometimes starts !


thanks people
