That's fair then, my understanding was that overspeed at WOT is what can cause it to surge, but obviously thats a super basic view

I see on the EQT page it says there's a hole for a speed sensor, would they be able to integrate that into our current ECU at all, or would it be just for manual monitoring?

^ I am wondering the same thing. The stage 1 looks like it can hit my next power goal, but I want to be sure before I rule out the pricier options.

As far as I know, there's no mechanism to monitor shaft speed in the ECU. You can still watch the gauge manually if you want, and ecutek or winols may allow the flexibility to define new map interactions.

I believe that's in anticipation to be compatible with the Mk8.

Normal IS38 is good to around 380-400 crank, at around 27-28 PSI, on 93. You can go a bit higher with e85 or a meth spray

Normally an IS38 tops out around 365 HP with FBO's and 28-29 psi on 93. You'll need ethanol to get to 400 HP. That's wheel HP. So 400 HP crank sounds about right.

RIP this turbo.

Talk about surge, yikes. Garrett seemed to just stuff big wheels into small housings without actually verifying it would work. 😬

If the stage 1 map ends up being accurate it looks like it can reach around 19 psi by 2300 rpm. That's better than my IS38, which also has a reputation for getting into surge. If the Garrett needs to be held back to boost like the IS38, with the ability to hold 29 psi to redline, that would be o.k. to me.
