About to hit the dyno. Any suggestions??

Hey guys I'm finally about to get my car on the rollers, I'm fairly certain I've crossed everything off the list mechanically anyways. Gonna bring a few cans of gas, a pail of VP M1 to spray, a bottle of boost cooler(in case the 100% meth doesn't take as well). Cooling system is where it needs to be, all fluids are good to go.

I've changed injectors from 1200cc to 1440cc. Both in tank pumps are good. I've still gotta change my water meth pump out.

But besides what I've mentioned and about to do is there anything else y'all can think of that would be worth letting me know??

I'm telling myself that 950 whp is very much attainable but in reality I'm knocking on the door of 1100+

Have a couple big high-capacity fire extinguishers of the correct type for whatever fire might need putting out.

Rule that no one is allowed in the dyno cell except for the person sitting in the driver's seat. No one is allowed to be standing behind the dyno cell outside watching through the open doors.

If you have ever had a tire come apart on the highway and beat the fender liner and quarter panel to death then imagine that happening at a wheel speed of 150 MPH and it is beating people to death.

I get that with the fire extinguishers that's gonna be on the tuner side of things. Tires are new drag radials. The ones I just pulled off have seen multiple 150+ mph pulls without issue I didn't see these ones having any issues.

I'm shooting for north of 1000+ whp

Dyno day is cancelled. A took the car out for a drive yesterday and a snap ring from behind the compressor wheel decided to leave the party. I'm slightly annoyed and I've barely got 800 miles on this turbo

Yep it sucks. But after talking with BSI and showing them what took the turbo out they realized it was on their end and will make it right
