Dyno run following rebuild... Options

[GT4WRC]

Plan has always been to allow the engine at least 5000kms before unleashing the boost controller fully, but I also wanted to ensure that the engine would last that long. So off to the dyno this morning to check to ensure that the fuelling etc was okay - especially as the ignition timing had been advanced quite a bit and the TPS altered to help control the idle (due to the HKS cams).
A gentle first run saw a lot of knocking above 5000rpm so the ignition was back off by some 4 degrees and another run undertaken. While there was still some knocking above 5k, it was nowhere near as bad. Not something that was very worrying at this stage as I am keeping the revs below 5k anyway during the running in period. I will, however, be placing an order for an Apexi FC and geting that fitted before the revs and boost are increased.
All was not bad however. Despite low boost and keeping ther revs down, we still saw nearly 200bhp @ wheels Certainly bodes well for the future :twisted:

Here is the dyno chart with 283kms on the rebuilt engine...




And as a referrence, here is a dyno from last year when mods were a Profec B EBC, 2.5" exhaust (inc decat & DP) and TOMs panel filter...
