Cam for torque question
I do have a FiTech 600 power adder sitting here in the box yet. I will install it this winter along with an FBO ignition system...you're most likely right AJ...that will more than likely clean up the smell.
No, I don't think so! Your ignition system for this cam does not need to be fancy. It will run on points if it has to.Well a dual-point system anyway.It just has to be stable and reliable.Your stink is not likely caused by a faulty ignition system. At idle, this is purely a mixture issue.And since the transfer ports are your #1 low-speed fuel delivery circuit, augmented by the adjustable mixture screws; this is the place to start.So the T-PORT sync is job #1, after the valve racket is fixed.
Earlier, someone reported a low Dcr with that 9.5 Scr and I verified that it looks to be around 7.8/155psi at sealevel. IMO that's not so bad, certainly far better than the stock Scr.It might be a little soft with your TC and gears, so;normally I might suggest to toss that 2200TC in favor of a 2800 at least.But the dyno chart shows that this engine is making pretty good torque by 2400, so Ima thinking the slight improvement might not justify the expense.And 3.23s ain't so bad.Your timeslip says the engine is pretty strong.I'm betting you short-shifted it to trap in third/Drive. Second with 3.23s is about 6450 plus slip, so maybe 6700/6800.Your dyno sheet shows a peak around 5800, but the test was stopped before we see where it crashes. We can see tho that the fall off looks to be real slow and gradual.A third gear trap mightabin 4400 plus slip,say 4600.At this rpm it looks like the engine finishes about 60 horsepower down.But worse is if you outshifted second at 6000 rpm to drop into third at about 4100, where power has fallen to something like 180. There's a good chance that holding second through the traps, the power might have fallen to the same 180, but you saved a shift.The result of that would be a little quicker ET. The correct gear for your speed might be 4.10s,depending on tire choice, to allow a full 3-gear pull, trapping at something like 6200. These 4.10s will make your car greased lightning to about 45/50 mph,again depending on tire choice. Of course now it's a city car :(
