dyno run for 2366 with Web street cam and DLRA 45s Options

[98101]

I bought this car a couple months ago, and wrestling with problems that I expected, and some I didn't expect.

Dyno shop got a noticeable performance improvement by reaming out the main jets. We played with the timing curve a little bit also. Unfortunately the clutch is contaminated or something and sometimes interfered with torque readings.

Now that I've read more about 2366 longevity, I'm not sure I'd opt for it. It sounds great and pulls harder than I'm used to in a 914 though.

The valve size and header size isn't a huge issue we're only talking .078" (2mm) smaller (your 42X36mm vs my 44x38mm) than what's in my 180hp 2600cc (78x102 w/9.5:1CR) and I also run a 1-5/8" header.

The main two things will be the cam and CR. My guess is the CR is also set way low.

I run a WEB cam 163/86b, .507/.497 lift 288*/298* duration.
With this cam you have to run between 9.0 and 9.5 CR, plus dual springs, CrMo retainers, keepers, pushrods and all the other valve train goodies. WEB says this is a race cam but to me it's a well rounded hot street cam for large displacement engines. Good, slight lumpy idle, gobbs of torque, for your engine spec it would be the one I recommend.

Timing I run 28* total, anything over 30* is too much, I bet you're pinging even if you can't hear it. At 36* your engine will have a short life.

On the clutch you definetly have a oil contamination issue, the stock clutch can handle 180 bhp, I cut my flywheel 2nd step an extra .010 for slightly more holding power.
I'm right on the clutch limit with my engine Hp and once last fall was the first time I felt any slip, after 5 years of hard launches.




BTW For some reason I thought you said a 80 stroke, but looking back I see it's 71X103mm so the standard base circle on the cam is fine.
