Not sure on the compression. Probably not very high given the 60 cc chambers. and yes that cam is very mild. i asked the builder for one that idled great and had some nice pep around town.Cool. Just think though these cars but down like 140-150RWHP stock so you have bumped it up quite a bit. Do you know your compression? I think the cam is pretty small too but pretty sure it is very smooth idling/driving. Any mods to the exhaust? The graph I assume that the final numbers where closer to the 12.5 AFR since it appears some of them where lean which I assume was the beginning of tuning. And do you know your total timing?
He actually alluded to that. He told me to pay more attention to the torque curve and the A/F ratio graph. But your right, we did some tuning and gains some power, and I learned a ton.Dynos are great for tuning engines but who tunes the dynos?
Many dyno operators won’t claim maximum HP accuracy.
Only that their dynos are for tuning.
So, you did some tuning and gained some HP.
I bought a used recurved stock distributor and saw the same. Said 24deg of mechanical advance so 12 initial should have given me 36 but when I was tuning it it was only doing 20deg of total mechanical advance by 3k RPM. I went up to 3500 and 4000 RPM and no change from 32deg total. So I changed my initial to 16 and have been listening for pinging and none so far and it does show 36deg by 3k.Total timing was 32' all in at 3000 rpm. Which makes me think, if initial was 12' and Dan at Mustang Barn said total mechanical should be 28 (he wasn't completely sure what he set my dizzy to), shouldn't i be somewhere up around 40'?
Yes we did. I had originally set the timing to 10' based on vacuum settings and pull 1-7 had those settings. After checking the mechanical cure settings at different rpms, we added 2 more degrees and did pull #8.Maybe I misunderstood, but did you make any timing adjustments on the dyno?
