AutoZone carries it. It's 22 bucks a can and treats as whole tank. Not sure if you're in the US or not but if you are just get in the zone. 👏

I usually throw some of the "Turbo 108 race fuel" as just a safety net, but I will see if any of the Zonies have the VP -- Rochester Ny is within those parameters :)

Just look on the shelf where the brake fluid and whatnot is. You'll see two types of octanium one is unleaded and the other is a little stronger. They both raise 93 octane into 100+.

Red line is Kraken , Blue Line is FM. Kraken setup was dropping boost past 5000rpm and still made way more than the FM.

Andy, like watching your videos and the Kraken comparison. I wanna make sure Im read this right... when you swapped to the low mount you did you retune and made that much more power? I watched the video but beer erases much of my memory.

Im debating going for that manifold to keep the upper rpms breathing but much lower boost level

I did add more ignition timing on the kraken manifold. I was unable to add the timing with the FM manifold probably due to backpressure. Other than that its the same engine but yes the fact that I could add more timing made a gigantic difference .

Andy, Thanks for the clarification. I had assumed this, but A-B testing isn't always done cleanly. Watched your videos before i got really addicted to the NB.

Just tuned a GTX2863R car, but with a fm log. Reminded me of this thread, and your car. Very happy with this turbo, and still think 400whp is nuts in a miata :likecat:

I ended up with right around 400 at 20psi at sea level. I genuinely wonder what the absolute limit of these things is, it seemed like it could easily make another 50-60. on E85 of course.

Very healthy. And it's "only" a gen1.

Sometimes I'm nearly maxing out my 2,5bar map sensor with a gtx2860r gen2 when its cold and it rips for sure. Never put it on the dyno, but VD puts out a very nice powerband and 340whp at ~20psi on an NA8, 102 RON
