Fu**ed Up Friday 😂
Back in April, we had Una Brau in for an ADE260 conversion. Everything went smoothly, but it wasn't quite making the numbers we'd normally expect. You could also hear it struggling and choking a bit at high RPM.
The car still had the usual 2.5" centre section that bottlenecked down to around 2" at the rear section, so we advised that to get the full potential from the setup and turbo, it really needed a full 2.5" exhaust system.
He opted for one of our systems, and we arranged a date for him to come down and wait while we fitted it and checked the map. Not something I normally do, but with a 6-hour round trip, I thought:
"It'll be fine — an hour in the workshop and an hour on the dyno." 🫣
First issue: the front pipe on our exhaust had been made incorrectly.
A quick call to our fabricator, who (eventually 😂) held his hands up and said, "Bring it over, I'll make you a new one." Fair play mistakes happen. New front section made, James fitted the exhaust, and away we went.
Onto the dyno...
Immediately, the car wasn't right.
FFS, what now? 😅
It was really lazy and nothing like it had been before or what it should have been. A boost pressure check revealed a tiny leak on a vacuum hose, but nothing major.
So we went all in Swapped the N75, Changed the actuator, Changed the dump valve, Tweaked the map, The whole nine yards
Still exactly the same. 🙄
By 4pm I turned to him and said:
"Looks like I'll be taking you to the train station, mate. Sorry."
Then I said to James:
"Just put that pressure tester on again and I'll open the throttle. Let's see if there's an inlet manifold leak."
Boom. 💥
The ni**le on the take off for the Forge dump valve had worked itself loose. 🙄
Ni**le lock-tighted, Map back to where it was, everything bolted back together, and the results were exactly where they should have been.
Thought I'd be home for dinner... 🤣
The treats and alcohol made up for it, thanks again Lee 💙🫶
Anyway, have a great weekend, people!
