guess this on whoosh page is misleading!!

*315whp / 316wtq using 93 octane @ 28psi is a dyno proven result with the S280
Don't get fixated on the number. The key is the shape of the curve. All dynos read differently and vdyno varies a lot based on the road surface. This is an iterative process. My tune is not complete yet on 93.

This thread is making it hard to not pick up one of these turbos. I haz a sad when my torque curve disappears over 5k haha. A good 300whp with 3-7k power band would really be the dream haha.

Just installed the kit yesterday. Fitment was kind of a pain in the ass but I didn't run into any issues. With my starter tune with WGDC @0%, I've noticed some boost creep with boost pressure rising to 18.5 psi at 7K rpm (running a 14psi TS).

That is my hp goal as well.

do you still have to shave that part of the block? I haven’t put my kit in yet waiting on manifold for whoosh.

Yeah not that big of a deal. My complaint during install was the alignment of the diverter valve, inlet and outlet pipes of the kit.

Did they hit things? My plan is to bolt it all up to the manifold and drop in.
The outlet hose is close to the driveshaft but nothing hits.
I installed the turbo with the manifold attached, like I did all my other FIST turbo installs.
When grinding down that "knuckle" I was very cautious which made it so I would grind a little and test fitment in an iterative process.
If I were to do it again I would be a little more liberal with the grinding, as there isn't a lot of risk.

Same regrets here lol. I started with a file and then I ended up just pulling it out for the fourth time and then going to town with the dremel. That worked really well. I wanted a nice 1/8” gap so I wouldn’t have to worry.

Did you properly set the preload?

I jus took a dremel to it for 30 seconds it was super simple because they already shave the compressor housing in that area.

To be honest I don't have an air compressor, so I didn't measure what the pre-load is/was. When installing the TS actuator there were only two lengths for which the actuator rod could be locked in, I chose the shorter of the two (more pre-load). It's possible I need to reduce the pre-load but my tuner wants to add some WGDC to see if that is necessary.

Rule of thumb when setting it is to line the hole up to where it perfectly sits on the wastegate flapper with it closed all the way. Then turn it two full turns and stretch it back onto the flapper. No need to really measure it.

Thanks for the information. That is essentially what was done then. I'll post if I had to change anything.
