I love it when you ring someone for a bit of advice and you get an answer you totally didn’t expect.
I’ve finished the engine build, and am about to sort the chassis mould, which means I’m not far from a rolling chassis. I’m gathering together some of the engine components I need and wanted to be sure I had the right advice on intake trumpet lengths I called Damien at Day Tuner – it makes sense to try and get this right before getting to the rollers.
Then Damien came up with the best idea: to quote “with your facilities, don’t try and guess the trumpet lengths, or go from rule-of-thumb. Print out lots of trumpets and we can chop and change over the day”. Bearing in mind pressure waves under the bonnet, you may actually want a selection of different lengths.
To the 3D PRINTER MINES !!!
