I was secretly wishing that someone with similar mods as 9sec9 would push the White as far as it could be.
This is pretty exciting times for us stock frame lads, the bar is about to be lifted
. Good luck with it all, & thank you very much mate.
Cheers Steve

I ordered one up today for my PPIHC car. I have an appointment for dyno tuning on the 14th. I won't be able to get before & after results on the same day, but hopefully we'll see a healthy jump in power.

.....PPIHC?
I'm racing my Evo up Pikes Peak in the annual hillclimb race. Startline elevation is 9,400 feet, and after 156 turns, you finish at 14,110 feet.

I disagree
There is a reason why compressor flow maps are printed in reference to "corrected airflow." These airflow corrections are based on various standardized atmospheric conditions. Garret, if I recall correctly, uses a standardized atmosphere of 13.95 PSIA and 85 degrees for all of there compressor flow maps. Mistubishi on the other hand uses something like 14.3 PSI and 75 degrees.
I believe turbines are VOLUME based and not mass based pumps. This can also be reinforced by some of the basic equations that govern isotropic turbines.
When you are pushing the maximum airflow of a turbo, you are choking the inlet due to airspeed and not mass flow. Hence the reason why inlet conditions become very relevant in this type of testing.
This is the way I understand it. I'm very interested in another perspective on this though.

Its like alot of threads they get posted up with out all of the information. I reckon i can vouch for 90% of people on this thread are interested in stock turbo upgrading and quite rightly myself included will not make a decision until the correct dyno results are posted!
FP White vs Stock IX vs Fp Green (all overlayed on one dyno sheet)
This is one of the main reasons why threads have so many replies! As above we are 17 pages deep and still haven't had the simple question answered!
If you paid 1 mechanic a day or two you could carry out the above test and you'd probably have mine and 4 other members orders by now! the main reason why people like me haven't bought there upgrade turbo yet is because we can be sure which version to go for and is there a red coming out? you probably have 100's of PM's asking the same questions why not save yourself the bother & carry out the test.
cheers

What were the mods on the FP test car?
When the original 2005 FP white rabbit turbo was released, FP gave it to Tym Switzer to tune and post dyno results. Initial numbers/charts released by FP/Switzer on EvoM were 370 whp on pump gas and 440 on race gas (on Switzer's Dynojet).
The test car in 2005 was an Evo8 and had a standalone ECU (AEM EMS) and stock cams. What does this test car have? Motec standalone? Stock cams?
