Finally Dyno’ed!
Finally, after the car throwing any problem it could at me. I managed to get my S13 on the dyno for a full session.
Massive thanks to Steve @ fctuning and Ali from Unit18
for helping getting the car in shape and of course mapping it!
I did have a mapping session with Steve a couple weeks ago, but during the run my wastegate got stuck open and had a pretty weak spring in it (around 6 psi) so that was the end of the night for me.
It was a bit hit and miss for yesterday as well, due to a manifold stud threading and being unable to tighten, so that had to come out and get sorted. I managed to get it back in with plenty of time thanks to Ali sorting the thread on short notice.
Met Steve at Motorworx’s in Marlow around six, got the car on the dyno and off we went!
The first run produced a somewhat high 2 bar boost due to the boost controller pipes being not in the right order, oops!
At one point we thought the car had done in a plug , but luckly it only had blown one of the intercooler pipes off (time to upgarde the clips!). With that fixed and new plugs in Steve got down to fine tuning the car.
Coming into the night I was anxious it wouldn’t make the power I was looking for, but the car surprised everyone!
The peak power of the night it made was 418bhp dead (356 @ wheels) however I’m not running forged rods, only pistons.
Because of this we decided it would be safer to tune it down slightly. It made several consitent 400+ runs so is very much capable of doing so.
My final figure for the night was a very satisfatory 388bhp at the fly (~330 at the wheels).
