Found Possible Fix To VVEL

wstar · 10-22-2011, 12:22 PM

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

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.

They are also a relatively small operation from what I understand.

Uprev: Yeah thats the VQ37VHR. Just wait till you see what we're doing to it next. Some people are going to cry.

seems as if they are moving forward on the vvel testing, looks legit! :P

I'll be shocked if they do but hey it has been 2 years since I they said they "had it cracked but didn't want to it do to lack of support, unless I sent them my car an unknown amount of time" and I think it was $40g it only takes two phone calls to lose faith.

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

Considering some other cars take 4+ years just for basic tuning, also the engine they are working on is a customers car and it took them a year just to get someone to volunteer to let them use the motor. I would give them a little slack.

i will say if they do it it will be a nice way to go about it because it is fairly painless to use the factory ecu. I just don't trust anyone that feeds me lines instead of just saying we aren't working on it at this time. not this give us ur car and 40grand ****, they actually feed me the i'd "have to get 200 people in on a group buy for it cuz thats what they get from stillen" thats bs just say ur not gonna do it.

why wont anyone just let it go? sure it will be nice/great/cool if someone gets in there and allows us to play with making adjustments on the VVEL.

But as it currently stands, it works really amazing and does its job very well already and is an advantage other engines dont have. the gains are probably extremely marginal and aside from that you would probably just completely screw everything up.

people are so friggin worked up about the VVEL cracking and 99% of these people wouldnt know the first thing to do with it if it was handed to them. i find it boggling that people are getting so hot and bothered that they cannot adjust their VVEL, just leave it alone... if someone does it you will know.

While I agree that this subject has been beaten to death... none of us know what sort of power gains we might see with adjusting the VVEL... so to say the gains may not be much is all just speculation.

yeah, we should definitely spend our time worrying about things that actually matter. Rather than PM'ing guys about the VVEL status, we should check in on the status of the fuel stave fix.

:i con17:

1slow370 · 10-23-2011, 12:43 PM

wasn't there supposed to be a swirl can for that or something? also uprev isn't a vendor so i can thoroughly voice my dislike of their public relations all i want. great product, customer service not to bad, but can be **** sometimes.
