yes im building another engine with uprated internals, but money at the minute is tight and i didnt want to over tune this engine then go and blow it up before the other one is ready, so i just went for a very safe figure to be fair to paul at engine advantages he had a very quick play then first run up made 311 second run up made 320 and i said thats fine leave it there, im sure the car can make more, but i just want to use it rather than worry about blowing something up without the money to replace it.
