How are these turbos holding up? Any track times or dyno numbers? I might have missed them, kinda skimmed through it real quick on my phone.

695 on fuel with 205s 12.9 @ 98 yes i know the mph seems off Im working on that

so this wouldnt tow a 6x12 enclosed with a motorcycle and gear inside? would it be easy to swap in a better turbo for towing if not?

Be sweet to just be able to swap turbos in an hour when you had to tow something

Thanks for the info! I like the Dyno number but that track time has me a bit worried, I wouldn't mind trying one just to see, I don't drive my truck everyday so this may be a good option if it makes good consistent power and is reliable, my truck is a street toy and track toy now :naughty:

this was on 35 muds and 373 gears with an exhaust leak
going back to the track oct 11 with 430 gears and 305/65/18 A/T

Why the gear change those tires aren't that tall? Easier to get the motor spinning?

373 and 35s was ok but 430s and 35s is a whole new animal

top end will suffer. with the power you make, 3:73 and 35 is just fine. your trap speed is about 12 mph short, i assume the exhaust leak was responsible for that if it truly make 700 horse.

heading to the track tonite again. as long as my new sct shows up in time

little bit better. eric sent me some new files to try out and they definitly felt stronger
truck went 12.7@104 1.79 60ft 8.0 1/8 @83mph

next tune was better

12.7@105 1.9 60ft 8.1@85

I also spun and hopped off the line in this one. with a clean pass i think this could have been a 12.5
