EFR 9180 Cast Long Runner Dyno Results

We finally have some dyno results from our new cast tapered runner FD turbo manifolds.

EFR 9180 T4 1.45 @ 18.5 psi
Semi Pport REW
TurboSmart Comp40 wastegates rerouted into a 4" exhaust
E85
3rd party testing/tuning by Mazsport in AUS on their dynodynamics in non-shoot out mode. That's about 640rwhp on a dynojet.

After the test and tune on the 25th of this month, the car will be run at 26+psi on the dyno. The time attack event is in 7 weeks they are preparing for( Vic Time Attack - Vic Time Attack | Racing | Track Day )
Emap sensors are also being installed at the moment. Car does run dual egt and shaft speed sensor. I will have access to the datalogs and once I get the information processed properly will share that too.

the semi p-port really helped the engine breathe !

Just curious, what's the rationale behind running a 1.45 AR? is it because of the 26+ psi target boost level?
but this a/r seem to have relative low lag even at 18.5 psi.

They need every last bit of power possible for be completive. Most of the cars in time attack are making 1000 at the tires. Yes the semi-pport makes a fair difference in mid/top end power.
