Today I decided it was time for Marvin to unleash his engine and see what all this work has achieved, I booked myself in yesterday and spent a nervous evening checking and rechecking things on Marvin, this morning I got up really early and with the light of a torch rechecked everything yet again. I topped up the fuel and drove over to Northampton Motorsport, the drive was not the best as Marvin decided he wanted to stall at every junction just what I didn't want.
I arrived for 9am and was greeted with a nice coffee and a chat whilst Marvin was strapped down onto the road. We chatted about the basic design of the engine what I wanted and what issues I had seen. We all agreed (well they told me) the jests were to big so it was over fulling on hard acceleration. we decided to roll the car as was to get a graph, then change the jests over and see if we could flatten the lambVt line as there was a big flat spot around 3000rpm.
Net results ? 65.5 bhp at 5800rpm and as I didn't want them to push him any harder than 6000rpm due to clutch slip (and me being scarred) there is defiantly more to come!
