1SlowSi

Last night I finally rented a dyno and strapped her down for her first tune on the new motor and setup. The numbers were surprisingly low considering the size of the turbo and fresh motor. I gave her what she wanted and didn't want any more timing throughout so it is what it is. Maybe she will wake up with E85 and more boost....hopefully. Im happy though.

430whp / 312tq - Final numbers, didnt screen shot it but have these last runs prior to.

Peak 15.8psi and leveled out at 14.7 psi up top.



Your thoughts please...

Those are almost identical to my numbers (s366/15psi). Once I switched to E85 and raised the pressure, the turbo really woke up.

1SlowSi

That's reassuring. What were your numbers though if you dont mind?

passmans2kny

nice numbers, but this turbo really shines above 20 psi

1SlowSi

^ yeah thats what I was thinking. I was expecting numbers around the 450-460hp area.

Backside might be to small? It is divided so I thought bigger is better?

turnover

That's what I was going to suggest ex housing needs to be bigger

passmans2kny

just to add I made over 800 on that housing and had decent spool

1SlowSi

^ yeah that. I wouldnt want to blame the housing just yet at such low boost lol. Once Im up high around 700 and causes me issues is when I might blame the housing. .91 divided seems to work fairly well and I did think about the bigger one but I didnt want a slug on the streets either. Screw it... 6466... <---not a baller like that

What is the most boost you can run safely on pump gas with your setup?
