Yes did several runs 400 BHP at crank compared to 343 stock..that’s on a Z4 E89 35is..

Over 650nm vs 500 nm stock

Dang only 400 bhp?.. Not downplaying you but i've seen people with 380 Whp on stage 2+ 93 octane. Was just curious what the bump would be from 95 octane since ethanol is nonexistent where I live. But I run the madditive octanium unleaded with 10 gallons of 91 and run the 95 octane map and have basically no timing corrections and logs look good.

Nice setup on a great looking car. I really like that sound too. Great power from minimal modifications; inlets/outlets/downpipe/CP/IC/LPFP, and 'only' on 18psi. What fuel are you running?

I'd been considering the twos when it's time to replace my stock turbos, but I'm limited to retaining OEM downpipes so not sure if there's any benefit there.

Going to try to dyno mine in a few weeks, expecting high 500s maybe 600 on kill map

Looks like a great result, with some conservative and well thought our mods on pump gas.

I would like to approach the 400 whp range, with FBO's and the 91 pump gas, if that is possible.

- who did your custom tune?
- what octane pump gas are you running?

Thanks!

I finally had mine tuned also

Mod list is as follows

Precision Raceworx Stage 3 bucketed Fuel pump
Viv 19T V4 Turbos
Upgraded 2" silicone inlets
5.5" upgraded FMIC
Upgraded Charge pipe
Decat Down Pipes
Upgraded Blow off valves
Sport Oil Cooler valve
NGK Spark Plugs 2 step colder (NGK 97506)

I still have the stock RHD outlets as finding upgraded outlets for a right hand drive car seems to be a challenge but even beyond that I think it put some very decent power down.

This was achieved at 18PSI of boost and I was told it will do more but I have to upgrade my clutch to get there first
