MadMarx Posted February 21, 2018 Author Report Share Posted February 21, 2018 If I would have done the engineering on this engine I would have offset the water ways from the chain housing so if there is a leak, you get a visible evidence "outside" the engine. The current configuration can leak to the inside and you won't know. As I found on the Web, leaks to the inside are not rare. The housing is now back in place, with a self made gasket and also Dirko. Yes, the engine is from John Eales. Quote Link to post Share on other sites

MadMarx Posted March 20, 2018 Author Report Share Posted March 20, 2018 (edited) The beast is running. The downside - primaries are too long with 32". I shorten them to 26". Edited March 20, 2018 by MadMarx Quote Link to post Share on other sites
Motorsport Mickey Posted March 20, 2018 Report Share Posted March 20, 2018 How have you arrived at the conclusion that they are too long Christian ? Mick Richards Quote Link to post Share on other sites
MadMarx Posted March 21, 2018 Author Report Share Posted March 21, 2018 (edited) How have you arrived at the conclusion that they are too long Christian ? Mick Richards I have a dyno sheet from that engine on which it is pulling through to 7k. Carbs are not changed, fuel pressure at high speed is okay, ignition is doing well, no pinking or knocking. The only difference is the exhaust. The dyno man says, as the power is recovering from 6,5k onwards, it must be a pulsing related issue that the engine don't get writ of exhaust gases between 5,9-6,4k and overriching. He thinks the engine has big cam and the primaries are designed for a small 310° cam. If the cam has 320 or 330 degree the pipes are too long.

Motorsport Mickey Posted March 21, 2018 Report Share Posted March 21, 2018 Good conclusion, I concur. Mick Richards Quote Link to post Share on other sites
MadMarx Posted March 26, 2018 Author Report Share Posted March 26, 2018 This week I will head down to Le Castellet in south France to the first season race. For me it is not so much a race, it is again testing under real conditions. Especially the roof spoiler is of interest to me. Is it of any use or just drag or looks only?
