Usually by this stage it's just a couple of thou lapped by hand, I machine cut everything to as close to identical as possible then Lap or Tip to get the exact clearences required.
The major PITA with shimless is non adjustable, as the engine wears the valves will sink and close down the lash so I add a couple of thou to spec to stretch out the inevitable, as far as I know my head is still fine on Crisp's engine and has many miles on it!
Usually it is a fuel cut for two step iirc. Antilag does a spark cut, that's why you get the explosion tht can backfeed.
I also have a high pressure ratio. 3:1 in my manifold. So also could be bad, that's why I went with the .81ar housing

te72: you brought up the AEM, do you have an AEM or did Albert switch over to one? I thought he had an EMU.
IJ.: Well, never mind. I was going to ask why you preferred shimless buckets over underbucket shims, but I guess if you get it right the first time you won't be touching it for a few years so it's not that big of a deal.

Shimless is lighter and you won't spit a shim on rev or antilag etc etc.
You you have shims, it is easier to do valve clearance, shimless the cams have to come out and they are twice as much.
Shimless is like $13ish for a bucket
Shims are like $7ish each

As Albert mentioned lighter and no chance of spitting a shim, I had my limiter set to 8300 and it saw it every single time I drove itSideWinderGX;1902095 said:
Nothing quite sounds like a 7M above 8000 it's a very distinctive noise!
It's possible to spit a shim with underbucket shims? Didn't know that!
Hoping to wind mine up to 8k this summer one way or another, the shims were the only thing I didn't want to chance. Even at 8k the rods aren't traveling fast enough to fail with the stock stroke, I'm kind of excited ha.
Albert: proefi, gotcha. Now we're getting off topic, I apologize haha, why did you switch over out of curiosity?

Underbucket will still have a thin shim on top so yes it's possible, the cam once over xx size tries to wipe the shim off the top of the bucket, that + any valve bounce = bye bye shim and
lash caps or shim under bucket is the best way but allot of custom stuff for a shim under bucket
Really too bad you didn't record any audio samples for our pleasure...IJ.;1902119 said:As Albert mentioned lighter and no chance of spitting a shim, I had my limiter set to 8300 and it saw it every single time I drove it

Not real sure if I have V1 or V2. Bought it about 3 years ago IIRC, the serial number starts with 1100-xxxx on one of the boxes, and 23xx-xxxx on the other box. Gonna sound like a real idiot, but I honestly don't know what I have sitting in that box. Friend of mine that did my head and swap (and is doing the widebody) told me it was a good deal, and to snag it, so I did. It's sat in my closet since, but that should change sooner than later.Albert;1902097 said:
Thanks for the info on the rev limit setups, I didn't know it had both. I might want to set up the anti-lag simply to pop off at people who are following a little too close...
Unless your name is Tucker... Apparently he had hell getting that engine to work. Shame too, sounded awesome on paper.mk3_7m;1902290 said:
I'm not saying this had anything to do with why it happened..
But Albert is a badass and knows how to use his supra
