power loss issue
Turbo Mini Forums

got a issue where at top end in 3rd and 4th i loose all power. i have to let off for 5seconds ish for it to return

if i let off and go straight back on it rele stuggles to boost back up. it barely makes it back to 8psi.

i dont think its fuel related as its just started and my aem stays normal.


any ideas? cheers

What happens when you let off for 5 seconds then put your foot back down? Does it do it again?

Does the engine hesitate or cut out completely?

If you're confident the fueling is ok, it could be the ignition. If you have any faults with the ignition, it will generally show up on load.

when i let off, speed comes down (naturally) and then it works again.

its just a complete loss of power.

il check over the ignition and go from there, think it needs a damm good rr session

As it only happens at top end in tall gears I'd suspect that your float bowl is emptying.

If you have a prepump filter check it for flow. I've had one clog up, reducing fuel flow.

scrap all that its running like a sack of shit in general. runs lean before boost, then perfect on for about 500 - 1000rpms untill it does the cut out thing.

just drove a 35min drive home which should of took 15.

Sounds like fuel pressure to me from your post before last then.

You could try the T piece trick to confirm.
