Very nice. What all did you have to do to get that sound and how much did it cost you?

What do you think it does sounds like? I have no idea what a 1280 is supposed to sound like and neither does Mark.

Maybe it's just that the idle is low?

The commanded idle is set to 950rpm, which is not low......I should be able to cut it down another 100rpm. I think I have a small exhaust leak where the header primary bolts to cylinder #6, so I'm replacing gaskets this weekend.

it sounds amazing, get a dyno of that beast

This is a great advertisement for ben's cam... I know when I saw the video, I was like yup I want that setup lol :)

I agree w/ nate.

Let us know if the leak fixed your issue

I think found the problem (and I should have done this a LONG time ago).
Rented a compression tester from AutoZone.
Pulled the plugs - 1, 2, 3 and 4 look fine. 5 and 6 are not so good.....the plugs are completely black.
Anyway, ran the compression test, starting with cylinders 2, 4 and 6 - they are on the front of the engine and easiest to get to.
Cylinder 2 - 175 PSI
Cylinder 4 - 170 PSI
Cylinder 6 - 15 PSI (!!!!) - I stopped after I saw this one.

Yessiree, Houston, we have a problem. I don't hear any banging when turning the motor over, so I don't think I dropped a valve and nuked the piston. I'm thinking either bad rings or a blown head gasket.
So at best, I was only running on 5 cylinders. But given the state of the #5 plug, I wouldn't be suprised if I was only running on 4. Dammit!!!

Pics of the plugs (5 and 6 are carbon-fouled):

Motor comes back out next weekend.

haha, my compression in 1,2,3,4,5,6 is all 120..... my baby's worn :(

damn 15 psi sucks. did you wet test that cylinder then? dump a lil oil in the hole and re-test it. if it goes up, you have a ring problem (or something round that area). if it doesn't, its likely your valves instead. your cyl 5 might be ok, at least from the looks of the plug its still firing, although very rich.

On your video it said you had a stage 3 cam which will give you kinda loopy idling so it should sound like that

ouch, sorry to hear that matt....

I hope its not the valves! Those were vacuum tested before I shipped them.

I can call it a stage 4 cam but that doesn't make it a big lopey cam:P This is why I hated the stage labels, but too many people depend on them to choose a cam.

I really hope it's not anything to do with the heads.

Buy new batteries, dammit!

thought about doing that but too much to do right now... its actually going to be quicker and more productive to charge these while I am working than to find time to go out and buy new ones.

Here's a couple new videos for ya'll. Please excuse the commentary - I hate how my recorded voice sounds.

In this video, you see my new oil pressure gauge. I think it's acting wonky because I neglected to run a ground wire to the pressure sender.

And here's a close-up of the exhaust with the car warmed-up (in closed loop). You can just barely detect a hint of lope from the cam....but it's still very quiet I think.

Questions/comments/constructive criticism welcome. A big thanks to Mark @ MP Racing for all his hard work on this build.
