VF11 Max HP?

Post by susiemk » Tue Jun 02, 2015 1:46 pm

I apologize in advance for the very silly questions, but again I dumped my VF11 very quickly & went for a TD04 then TD05 on my SS (BXSS)

Does anyone

1. Have an idea of the max crank HP the vF11 should produce without restrictions from the engine such as poor flowing heads?
I'm guessing 220-250chp but have never seen flow data of this turbo - I'm estimating 360cfm based on the Tbird's 381cfm & similar sized compressor wheel (vf11 - 37.5/52.5mm vs t-bird - 39/52.5mm)...

2. Know the max WHP made on a VF11 with a ej22t - I've seen a Youtube vid claiming 175whp @ 11-12psi - does that sound correct?
Has anyone dyno'd a Rextronix chip with 16-13.5psi vf11 boost tapering???

stock boost is about 8 psi @ 165 chp, so I don't think 3 psi makes it 175 whp

^Its possible to make pretty big gains at lower than stock boost levels by freeing up the exhaust / intake / cooler intake charge so while it may sound crazy - you never know...

I actually gained 28 "GTHP" on my Gtech-PRO at 5psi with intake / TBE / IC vs the same SS's stock baseline @ 8.7 psi (I probably documented this as BXSS my old inactive username).

The Gtech-PRO reads lower than a mustang or dynojet & rated my stock perfect running 110k 4eat SS running 8.7psi of boost at 102GTHP...
