Found Possible Fix To VVEL

1slow370 · 10-22-2011, 07:39 AM

i don't think uprev even wants to try to care. I want to know if you jack up the vvel curve can you actually hit the pistons? does sam have an extra block and set of heads lying around somewhere where he could throw some clay on the pistons, slap the head on, time it, use a crescent wrench to turn the vvel fulcrum shaft all the way open and turn the bitch over to see if it actually can touch and determine the clearance? then advance and retard the timing all the way (maybe just do it with the chain?) and turn it over again to see if it hits. why don't we start here. because if nissan built enough clearance into the system well then uprev has just been lying out their @sses the whole time.

Vendor bash much? The extra clearance and adjustment room, as I already mentioned, is most likely for manufacturing tolerances, and if anything probably a safety margin so you don't hit anything if things get a little out of adjustment over time. Meaning it won't be universally available, usable, or safe. UpRev's been working hard on tuning our ECU for a long time, so it's kinda hard to claim they don't care either. If you'd like to purchase your own crate engine from Nissan for 8K to screw around and damage something and maybe figure out a trick to gain +3rwhp sometimes for some engines when the stars align, feel free

Haha I actually have an extra set of heads for just that. And I'm not talking about the adjusting screws I'm talking a good ole valve clearance test it takes 2 hours and doesn' involve starting a car. If sam has a short block set of heads and a timing set we could lnow exactly what the vvel can and can't be adjusted to

Go look at there Facebook page, there are pictures of them working on our block messing with VVEL recently and some in the past. They do care, but the Z is not the only car they work on.
