Just a more detailed post of the tune day:
Picture of the dyno, you can sort of see the dyno graph in the rear. Graph stops at 4,500 rpm
So something was stopping the car from making power and taking timing on the day.
At first suspect cam timing or compression. But checked cam timing on the dyno, and did a compression test. ~175psi across all cylinders.
Spark plugs changed. Dropped the exhaust. But made no difference. Still stuggling to make more than 310rwkw
So Trent tried a run on e85 but it still had the same issue. Car only took about 12 degrees of timing normally about 20. Only bumped up power to 315rwkw @ 4,500rpm
It is a suspected faulty injector so off to get it checked.
Pulled the injectors out this morning. As we have a suspected faulty injector. A simple quick test shows they seem to be ok. But will be sent away for a more detailed analysis
In prep for the Dyno. Scotty @ Scotty Customs did:
Turbo install
New fuel pump Walbro 460L/H
Metal turbo elbow, as a silicone one was a bit close to the manifold
New Return flow intercooler bend. As the old one was quite crap
Turbo Elbow:
Intercooler bend:
Things to do over the next month:
1. Fix issue with car that is holding it back
2. Fix heater hoses touching manifold
3. Fit oil cooler
