Daw ultraflow vs flowmax 2.5+

tmoffat86 · 05-20-2023, 09:58 PM

Ive searched and searched and I cant for the life of me find any info on the difference between these 2.

about to pull the trigger on a turbo and decided on one of these but not sure which one.

I assume the ultraflow is slightly bigger and spools slightly later but I can't find any concrete info.

any help is greatly appreciated.

The Ultra Flow's exhaust manifold is larger along with the turbine and compressor wheel compared to the V2.5+. Im not sure if the V2.5+ manifold is slightly bigger or not. I would go with the Ultra Flow personally as you have more headroom to push the turbo. I'm on a DAW v2.5 or v2.5+ i dont even know anymore and I wouldve definitely went with the Ultra Flow if I had waited a bit longer

v2.5+ spools very fast. If you're not wanting to make above 600-650whp and you want the quicker spool, the FlowMax is a good choice. UltraFlow has 700+whp capability and more headroom as Blacksapphire said. Can't go wrong with either, just depends on your goals and preference.

Sheesh. 28 psi by 3350rpm lol. My tuner was a little less aggressive and we hit 28psi around 3800rpm (to save my clutch). Definitely working that turbo hard with 90%+ wgdc.

Is there really anything that can be done about the wgdc? Or is that the byproduct of having 27-28psi and how my tuner is tuning my car?

Eh mines the same right around 87-90 wgdc, hitting max boost between 3300-3400.
