When you consider the "pulls" started at different RPMs you might change your evaluations, and from the similarity of the curves there is a problem with either fuel ratios or timing and likeky both!Hi Richard,
the only data I have on my actual cams are as follows:
Cam Lift Inn/Cam Lift EX-Duration-Lobe Center Angle-Valve Lift TDC
10,9/7,3 - 270°/270° - 102° - 2,3/1,9
As I told you I cannot give you all the data you need but consider that some metal removal has been already done when I run with racing profile (C&B corsa).
So no probelm for that and anyway I do not want racing profile anymore.
I want to run fast soon, not only after 3500, push hard up to rev limiter without having annoying ticking.
My engine has 10,3:1 CR, full CSC manifold exhaust system, 164 QV plenum and ported runners, competion ECU without MAF from EFI Technology, fuel pressure regulator increased, fuel pump increased, increased injectors, engine lightened flywheel, lightened connecting rods, K&N cold air intake, increased aluminium radiator, Denso Iridium sparks and so on.
Now at the end, after a lot of regulations and I don't remember anymore how many tests, it is driveable as a stock 75 and runs very fast.
Which cams can you sell to me and, of course, at what price.
Firstly Gabork, note that the dyno had "0" compensation for driveline losses and results at the wheels. The SZ motor is quoted by manufacturer at the flywheel dude. this motor is making ~230HP at the flywheel, so the SZ cams would probably not be in contention.I think with these results (200-211Hp) and smoothness being a priority, little noise etc, the SZ cams, which I initially suggested, would have shown well off here! They are smooth in power delivery and very quiet. Power under these conditions should be around 210HP.
Maybe thats why I suggested to test the SZ cams in the same set up?You NEVER compare dyno results from different dynos, .
OK, let me know. I could be interested in the Stella cams also if you choose to keep the RJ cams on basis of ticking noise. As I will use the cams for racing, noise is not consideration at all! What I am looking for is a cam with a little bit more Power than the SZ cams I have. The SZ cams are very good for revs but lack a bit on lift. A bit of regrind could actually fix that, but as it is I have regrind cams with good potential already! However I would like to test other cams also. There you could come in!I'm deciding.
I'll let you know...
