Blown VVEL !!!

Why did the engine spin up to 8k?

Coon-azz · 08-28-2012, 10:41 AM

Really sorry to hear this. I've been watching the build and was hopeful. Anyway, done that myself years ago; blew piston #2 threw the CF Hood. the NOS bottle rolled on me and the motor ran lean...very expensive mistake on my part. Wish I had some spare parts to send your way, but I don't. Let me know how I could help other than sending you a lot of $.

Very sorry about the failure. Good time to start the build though! It's been on my mind too since my Time Attack competition got a recent boost in power.

Makes me very glad I installed the AM Performance baffled oil pan last year. Does anyone else make a suitable oil pan or are you going to convert to dry sump?

it wasnt like last year with a different dealership , They told me that I should reinstall everything stock around the engine before they take picture...
I got the 7AT replaced there
but I couldnt tow the car at that one and my only option was the new one near of my home.

you should've tried the same dealership man..atleast they knew the history of the car.

It seems more like oil starvation than anything else. Were the oil levels ok, before and after track use?

stock engines can take close to 8k rpm occasionally without problems. 7500rpm is where nissan felt safe warrantying the engine for 60k miles

Very interested in HR head swap. How much is involved besides different wiring?

I do not have the funds right now for a dry sump !!!
I wish I could do that but no im gonna look to make something up in there !
I have a few good ideas that should do the trick.
But a spacer will probably be added to the mix

due to some restriction and last minute problem . that was not possible .
trust me I wanted to tow the car there !!!!

yup I saw so many guys getting their rev limit to 8000 rpm ...
my reason to have it there wasnt to look cool or anything but only to stay in gear as much as I can which was perfect with the gear that sit in my diff !

I havent fully figured it out yet ...
but from my research it seem I have everything to make it to work ..

yea i think with the VVEL heads they set it at 7800rpm. you can PM bkleeman if you have any questions and he might answer. BJ, Dwnshft, might also know since he races in the conti-challenge team. and yea, having those extra revs can really save you a 2-3 or 3-4 shift in a straight going into a corner which helps with laps times, especially if you are running the 4:10 gear. little different for you since you are auto though

But thats silly to say. A stock Z engine can probably handle 20 pounds of boost for a while then Boom like what happen here. Its cool people are trying new things but this seemed silly. IDK.

it's not silly at all dude, lots of people raise their redlines a little over stock when tuning. if it's tuned right, it should work fine. it definitely looks like oil starvation played a role in this problem, not completely the higher rpms (though that was part of it)

Sorry to hear about this as I really liked where you were going with your build. This combined with all the other track issues (high oil temps, high diff temps, high brake temps, csc problems) really makes me nervous about tracking this car.
