Just a question for AFC users running the stock turbo... What is your maximum value for HZ that you have seen? List your mods, and boost level. This is a nice way to see how much air (which makes power) peoples car are pushing

I'll start.

1800 Hz @ 7500 rpm

03 stock turbo (9.8T)
3 in TBE no cat
3 in Intake
MBC @ 21 psi (max)
Upper IC Pipes
264's
Fuel Pump
Dynoflash mail-in

 

Max Karman readings?

As an update for me, I currently see a max of ~1870-1880 at 24psi on race gas while running 12.0s at 113+.

- Catless TBE
- Walbro 255
- K&N drop-in
- MR DV
- Hallman Pro MBC
- Dynoflash
- SAFC (adjusted when using race gas)

 

Thanks for the pointer to the other thread.

 

2126hz max at whatever the stocker could put out with the hallman cranked to the max and an injen intake cone.

 

2496 karman hzs it was on the dyno peaking 30psi on my greddy kit i put down 445hp on a mustang dyno but on 25psio it would hit around 2200, and on 20psi it would hit around 1980
