Default Turbo upgrade coming for the Undead Sled

I'm trying out some upgrades to my ST80 from Forced Inductions. Basically Jose and company are turning my ST80 into a SX80. I'm keeping the 80mm compressor wheel but i'm getting the race cover. The turbine side is being changed from a 83mm turbine to the 87mm turbine wheel. I'm also going from the 1.00 a/r to the 1.25 a/r as well. I was very happy with the driveability of the ST80 and am anxious to see how the new upgrades affect spoolup and power. If I don't like the way it drives I'll just downgrade to a smaller a/r and call it done.

With the 1.00 a/r ST80 i manged a best of 10.1 @ 136.6 MPH on 16psi. I'm hoping to run 140+mph with the new turbo and break into the 9s.

Did the 60ft times drop with the bigger turbo or was that 1.48 60ft with the smaller turbo a best?

1.48 60' was on a prepped track with 26" tall tires and the 76mm turbo. I now run 28" tall tires with the 80mm turbo but I haven't run on a prepped track yet. The good news is the car always goes low 1.6's with shitty track prep. Should be awesome once I get some adjustable shocks for the front and get on a prepped surface.

You will like that 87mm turbine wheel, I have seen some pretty excessive back pressure with the 83mm turbine wheel at 750-850whp,

750-800 whp is the range i'm in right now too. Jose thinks that I'm going to pick up a ton of power on this. He said with the race cover it's and larger turbine it's a totally different animal.
