Now of course I dont have any dyno proof, since nobody in the protege community actually gets serious to get cams and get the thing dyno'd and tuned, and all the rest of it, but I really think that you can get a lot more power out of a BP.
I mean the stock 94-97 miata intake cam is only a 232 degree cam, and its an improvement on our intake cam. Now say you get the TODA 256 degree set. Thats a lot more duration, plus with a set of cam gears you would be able to dial in some overlap to get the scavenging effects to make it even more benefical. The reason why you have to use the lockers is because of the ramp-up and ramp-down time, meaning the valve is open for a longer period near its max lift, which by the way is also higher than the oem cams.
Randy S. just built up a nice street BP. Street meaning its still got a ton of mid-range torque, at a sacricfice to top end power. Its currently pulling about 155 hp at the wheels, or a little less than what something like a stock Integra Type R has, however, when you add in that the BP has FAR MORE TORQUE, you'll see that its probably a quicker car, depending on gearing.

Maybe I'll buy a set of TODA cams when I start building up my race engine on the side.

There happens to be a group dyno goingn on the 30th. Either I'll have a baseline dyno figure for my dx which I can compare to when I get the gude head on, or I'll have a dyno of the gude head.
I'm not pushing for the gude head to go on any time soon. I just spent enough time under the car (half of saturday, all of sunday), and I'm sore in some places still to this day (my neck has finally recovered)! I had to put my lower tie bars on, and I decided to finally replace my oil pan gaskget, as I knew there was a leak towards the rear of the block. It's holding up nicely, and I must say that Ultra Grey from permatex r0x j0r s0x. I put oil back in the block and let the car run till it came to normal temp, turned it off, and then waited 15-20 minutes to see if any oil leaked. Turns out, I saw one drop of oil when I came back out to check for oil leaks. Seems that either the valve cover gasket needs replacing or the leak is coming from somewhere else around the head. There's a "wetness" (because I could never really tell if it was oil or not) between the block and head running to the exhaust manifold right on the corner of the first cylinder. It's odd. I'm going to replace the valve cover gasket when I get a chance and see if that eliminates the oil leak. Figure I better do all this **** now, if I want to run in any autox events (read that there needs to be no leaks during tech). While the car was on jackstands, looking from underneath, I saw a bit of oil on the exhaust manifold. Now I know wtf that smell of burning oil comes from when I stop and get out of the car. Geh.
Ooookay. Simple reply turned into a long story. Weeee.
Doka doka.

And bein that i've just started tryin to learn cam timing, i didn't quite understand if that '8 degree retard' would be on the intake OR exhaust cam????
