New Bolt in turbo... FP White Rabbit.

So what is the recommended injector size for the rabbit??
Also, if you run alky I know Al said you DON'T need to upgrade injectors b/c it works as additional fuel...If you are planning to run the white rabbit with alky do you guys think you will still need injectors?? (I will probably buy them anyway lol, im just curious what you guys thought!)

Wow!!! I can't image what it will do with some 272's or 280's cams, ported head and alky injection!!!! Sweet numbers!!!!

First of all, we wanted to see what results we could attain with the turbo and as little mods as possible. The results with this turbo are impressive to me, not because of the amount of modifications the car has... rather what it does not.
Vehicle as tested:
Stock Engine (Stock internals, stock cylinder head, stock camshafts)
FP White Rabbit Upgrade Turbo
Hallman MBC
Denso 660 cc Injectors
Walbro 255 Fuel Pump
Stock Airbox w/KN drop in panel filter
Custom 3" intake pipe to stock airbox
Tial BOV on stock intercooler plumbing
Stock FMIC w/stock plumbing
AEM EMS (Speed Density, No MAF)
Stock Ignition (Plugs gapped down to .018 to prevent misfires)
3" Downpipe, offroad pipe, modified HKS catback exhaust
No alcohol injection or intercooler sprayer
As you can see by the above photo, this combination is very stock appearing.
Here are the results after tuning the combination on our AWD Dynojet chassis dyno. We pulled the car a total of 17 pulls. 1-6 were pump gas pulls on 94 octane Sunoco pump fuel, 7-17 were done on VP Import (because it's all we had in stock today... at these boost levels, C16 would be fine.)
Video of the last and highest pull can be found on our website under videos.
Run 6 was the highest awhp/awtq attained on 94 octane pump gas, run 16 was the highest awhp/awtq attained on racegas with no changes other than tuning. Just because I felt that the filter was becoming a restriction at the higher boost levels, for grins I pulled it and the airbox lid out for one last pull... hence run 17 which is the best of all.
Boost levels on pump gas were 23psi settling to 21psi, and racegas boost levels were 27psi settling at 25 at redline. Robert and I have discussed a couple of tweaks, but I'm happy with the turbo's boost curve. We are using a Hallman MBC which in most applications allows a bit of a boost spike initially, followed by a taper of boost.
I am trying not to leave any information out of this post, so if any of you have questions, please feel free to ask.
There is a lot of potential in the use of this turbo in a streetable performance combination for the Evo. I think we've shown what proper application of components and proper tuning can realize. There are more modifications we can do immediately to extract more power from this combination, and we are working on those as we speak. In association with FP, within days we will dyno initial prototypes of some camshafts for the Evo that we hope will give us the best overall performance gains. This will be done with no other changes made from what is listed above to insure that we keep the testing results accurate.
Take care everyone.
