I would like to know what was done to that ST to get those numbers?

Those are the big mods. It’s also on super light 18” Rays wheels with drag radials.

geez, that will do it!

Pump really wasn’t needed...Meth makes up for that. The pump is there for Mods that are coming.

I’m going out on a limb and saying 11.80’s will be happening on 93 and Boostane within the next month or so. Ethanol tunes will only get quicker.

Do you know the meth kit?
Was it sprayed onto the IC or into the hose?

It was used for fuel not cooling...Upgraded IC handles that.

It's sprayed into a Prometh sleeve right before the throttle body. It's installed it with the intent of bringing the MCT's down, didn't want the car to be dependent on the meth for fueling. This video shows how it's plumbed in:

Thanks Theo! Awesome run! Is it used for fueling at all?

How is the truck holding up under all the abuse and added power levels? Any trans/clutch issues?

No issues thus far. Bigger turbos are on the way. I plan to upgrade the clutches on the 10R60 eventually.

Any launch tips?

Any launch tips?

Sport Mode, Traction Control off, stand on the brake, get RPM’s over 2500, floor it, release brake, GO!

I own both a 2021 ST and 2018 TrackHawk. In stock form the ST is no match for the TrackHawk. However, the Trackhawk is nearly double the price. The whine of that blower is music to my ears but the ST is the best value in the performance SUV. Throw 10-15 G at the ST and you have a true world beater when it comes to SUVs.

Tried this with my 2021 ST and highest I could get the RPM's was 2200/2300. I've read elsewhere the happy spot for launching is 2900, but it seems the computer's in the 21 models won't let it choot any higher than the 2200/2300 mark while standing on the brake with gas pedal floored and TC off. Any ideas on what else may need to be turned off/deactivated?

We use to (back in the 60s ) did the brake and laugh , but with built tranny and stall converters.

Wouldn't holding brake and 2500 rpm be hard on tranny?

Unless modified.
