Loss of all power at 5k rpm??

[hubbygt]

Weird one here, all boost rapidly drops off and then I cant even get any drive whatsoever. Checked for leaks on all intake and vaccum pipes but they all se fine. Also this has only happens since relocating the air filter to the front bumper. Car still seems fine up till 5krpm. Any ideas?

 

[Chris@CCM]

u say a loss of drive ? like a sliping clutch ?

 

[Phil]

the relocated filter might just be flowing free enough for fuel cut?

given that you driving a glanza, fuel cut is not really "smash your face off the steering" wheel stuff, so that loss of power could maybe be fuel cut.

no yes maybe?

The clutch only 6 months old and hasn't done many miles so I don't think it's the clutch. Plus it cut out last nite when it lost power and was a struggle to get started again. I'm running a Dastek Qchip piggyback so that removes the issue of fuel cut I think maybe? Thanks for the replys folks

is the engine management light coming on?could do a diag and see whats coming up?

 

[hubbygt]

All 3 times that it's done this there have been no lights showing on the dash it simply just dies?? I thought maybe it could be the filter getting too much flow of air so I taped up a 1/3 of it to restrict it a bit bit to no avail

I thought maybe it could be something sensor related maybe? Really stumped on this one

 

[Chris@CCM]

fuel pump dieing ?

 

[hubbygt]

It's an uprated pump mate that was fitted in January aswell but I think it could be fueling related so I will check the pump and filter to begin with.

My Glanza wa doing the same thing a few months back which turned out to be the spark plugs?

 

[Glanza_cl]

knock sensor?? but as above check the plugs and leads are ok aswell. is it only at 5k revs and no other time?... alternator maybe?

 

[hubbygt]

I will check the plugs as I checked the leads already. Yeah it's only at 5k rpm. Will also check alternator as it's an old unit. Also it let out a couple of puffs of oil smoke after the boost dropped off a few times bit never ever smokes at any other time. Using it as a daily drive at the minute so i'm gonna have to get it sorted asap. Can still drive I guess but it just need sorted

Well finally found the cause of the problem. The 90 bend of samco I was using to relocate the filter to behind the grille wad collapsing when at full boost and the fuelling was a bit out so had to get her mapped again. Done a compression test and came back a solid 145 accross all 4 cylinders. Picked her up today from being mapped and I can say it's finally finished....... for now anyway lol 212.7 atf 176 atw and 198.5 lbft. Plenty more to had out of the engine with a bigger turbo but this set up really does suit me down to the ground. I'm a happy lad today

 

[Paul147]

Nice one mate and thats a good power figure, Id be well chuffed with that!

 

[hubbygt]

Yeah well chuffed with the figures. Feels great on the road, that's the main thing. :drive:

 

[Rory]

Where was it being mapped hubby?

Good to hear it goes well on the road, and your not fussed about the numbers

 

[stuart]

Nice figure mate.

 

[hubbygt]

@rory it was mapped at Dastek in dagetty bay. Always had good experiences there.
Cheers for the comments lads

dont mean to piss on your fire,but 145 across all is very low,i wouldnt touch a car under 150.

 

[hubbygt]

You ain't pissing on anyone fire, it's a low compression forged engine. Don't see a problem with the figure at all imo

oh shit sorry,forgot you forged,lol!
