FP White vs FP Green - same day - same dyno comparision
Today, I had a rare opportunity to conduct back to back testing on two very similarly equiped Evo 8's with basic Stage III configurations on the same dyno and same day.
These cars both had what I consider basic performance upgrades - stage III which includes - intake, full exhuast and cams. Each car had FIC 750 cc injectors and a walbro fuel pump. Both had Hallman MBC's Each had custom Dyno Flash tunes.
The first car had the FP white which was run on 93 octane with 25 psi peak boost. As compared to stock this turbo has the same spool up as stock and holds the boost all the way out till red line, which is very impressive. It feels great on the road. We made 362/363 which was decent numbers but not that much more than we would expect with a stock turbo. I think the gains would be more significant over 7,000 rpms. My take is this is a turbo suited for someone who absoultely cant have any more lag than stock but who wants a mild upgrade over stock.
The second car had a green - much more popular choice This car also ran 25 psi on 93 pump gas and made 393 whp. You can see on the dyno chart its a bit laggier in the low rpm power range but lets face it most of the time we are driving over 4500 rpms in any event. I personally would take the green every time. More power and TQ and a lot faster car in exhange for a trade off on slightly more lag and a loss in low LOW prm use.

FP white seems like kind of a waste of money... I dont see how the performance would justify the cost compared to a stock IX turbo- green is cool, but outdated- HTA green maybe if you want to deal with forced performance wait time, or go with a BBK and not be disappointed

To me the white is too close to a stock turbo in performance to justify the expense to aquire it and install it
However, with that said those who are seeking to have the least possible turbo lag may want a turbo which makes more power with the same spool up as stock

I will say that the White turbo gave me more of a "feeling" in the seat of the pants as far as an improvement than was reflected in the dyno numbers. It does seem to give a very broad power band and holds the power well up top.
My conclusion is to recomend that all my customers just go for the red if they are considering a stock location turbo.

That's what I wanted after playing the big turbo game on DSMs for years, I almost got a Red but ended up with a BBK lite. It spools like the White and makes power like the Green in your graphs.

I am still hoping for someone to develop a variable vane turbo for the evo, This esentially gives a variable A/R ratio. The geometry of the vanes change as the engine changes its demands. Borg Warner has a nice unit that is in use on the Porsche, starting in 2007. Maybe the FP black will have this low lag/high top end genie. Robert, how about it???
