VoodooShark's V2 Buttz Build

I'm going to incorporate an AFR failsafe besides my GA. Have you thought about going that route? (Getting an AEM AFR failsafe, too?) I'm definitely going to have an AFR monitor since I'll be methanol fueling-dependent. I want a split-second intervention if I suddenly go lean under full boost, you know?
So you basically methanol hydrolocked (those bent rod pics) and are trying to address too much methanol flow? I need to think about that too. Gotta address both too much or too little flow. Does VT have injector-cut rev limiting options instead of the AP spark-cut based rev limiting?
Not so much hydrolock. More like an over exaggerated wotbox effect. A wotbox works by cutting spark between shifts so the cylinder is full of fuel and makes a bigger flame, forcing spool. When I hit the rev limiter the ECU cut spark and fuel, but methanol kept spraying as it was still in boost (albeit declining). When the spark came back on the cylinder was full of methanol and ignited an enormous flame front, going mega-spool.
As far as VT, I`m only just getting more familiar with the nitty gritty of it but I do know I can set up the conditions under which it goes to fuel cut. There may well even be a way for it to dump WGDC if it goes lean, which would kick ass.

Ahhhh, so there may have been both hydrolock and overboost going on. You wouldn't been able to see anything over ~30psi due to having a 3-Bar. Heck, you could've spiked much, much higher.
He isnt spraying nearly enough meth for hydrolock
Good to know. Must've been just overboost that made rod 1 turn into a contortionist.
I'm going to spray ~24-28GPH, so was pondering the possibility of hydrolock.
Nothing particularly new to report. Opted to have some head work done just to ensure the engine is in the best possible shape it can be when it goes back together. The shop doing some of the machine work actually specializes in NASCAR engines, and if they can build a motor that is designed to run at 8-10K rpm for hours on end I`m pretty sure they can do a fine job on mine.
No, but yes. I would have left day after tomorrow, so no. But I can reschedule the trip so yes.

What's the ETA then on getting the car back? They going to tune it possibly still?

Middle /end of next week as long as the head makes it back from the machine shop. It's done, they just pick up work in batches (which I understand despite it hold up my build). After running the last logs and getting the dyno estimate it gave I don't think I'm going to have them tune it. They will be doing the dyno break in so it's ready to rock but we're just going to convert the previous map to VT for the new motor and dial it in from there. If the 460/420 numbers are close I'll be really happy.

How much was their dyno estimate? Btw, freek does dyno tuning just have to schedule it.

Got some good news today. Not so much my car, but about the shop in general. I just learned another local I know had his engine built at the same shop. They did basically the same job on his, did the dyno break in, then dyno tuned it and told him to have at it when he picked it up and he hasn`t had a problem since. Granted I`m not having them tune it, but they are doing the dyno break in so it`ll be ready for tuning when I get it back. To me, that was a load off my shoulders.

The dyno break in is $200 and takes about 4 hours. Full dyno tune is $400 and up, depending on the details.

Saturday came and went and I obviously didin`t post up, so it`s not finished, but otherwise nothing but good news. Machine work went without a hitch, they just didn`t have the time to finish the install and break it in. Shop`s closed tomorrow, so I`m looking at wednesday, maybe thursday to get it completely buttoned up and the break in done. Just a few short days!
