is that with the bigger 1.32 AR

thanks

This compares well to my dynapack result of 472rwhp @ 7497rpm @ 1.3 bar @ 1737.9 Nm @ 6932 rpm (rear wheels tq!) street ported S5 engine on pump fuel & water injected
^ this was done with a TO4S which had a P trim rear turbine on 1.32 rear housing, the P trim old turbine is the same minor and major as the modern TO4Z turbine except the final exit profile of the wheel in the TO4Z is much wider with not as much back cut to it (which is why its so much more responsive).

If you step up to a T51 with R trim turbine wheel expect another 130+rwhp at same 1.3 bar boost level @ 7900 to 8100rpm.

YES it makes that much difference !

Rice Racing - Interesting facts

na still with the tiny 1.15 AR Erdin :D

Yes Rice, Water Injection defo helped me run with Pump fuel at these boost levels with very very low knock values :), going to add a second jet into the inlet pipe of the turbo after my first drag runs this year so I can do back to back comparisons also lean out the mid range slightly as this is a little fat with fuel at the moment. I will also go to 21 psi when I add the second jet ;)

Dougie, my mods are Half Bridge Ported 13b rew, 2x850 2x1680 injectors, twin bosch fuel pumps,swirl Pot,HKS Twin Spark, and of course Garrett T04Z with 1.15 Hotside

Engineis going in this week. I will be up and running ASAP. Should have some #'s by July.
