New Bolt in turbo... FP White Rabbit.
the comparison against stock cars is a bit unfair as the White Rabbit is running AEM EMS. How about a real fair comparison with stock turbo tuned on EMS and White Rabbit tuned on EMS. Or both on flashes.
I still can't get an idea of how much more whp I can expect over a stock turbo.

my biggest question is when does it actually hit full boost. I understand that the turbo is making good power....but by looking at the graphs it doesn't hit full boost till about 5k.
that is not like stock....at all.
on my turbotrix 50 trim....i made 430 on pump with 272's and it kicked at about 4500 to 5k....i just want more info and someone to confirm the spool characteristics of this new turbo....cause in the beginning i read....."Spool is like stock" and then i see a dyno chart that shows full boost by 5k.........

BTW there is a big difference between full boost and full power. Although its making peak power at 5k or so much alike a stock car, it could of been making full boost since 3500. We don't know but I wouldnt mind knowing when it reached whatever you had the max boost set at.

Simply Put "Another Switzer Performance Innovation!"

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.

You are reading the dyno run wrong... This is full power not full boost. I hit full boost @ 4100K but my full power is around ~5K That does not mean I hit boost @5K. You start making power and it builds up then falls down
Get an AEM and have it tuned so we can compare. Then you can have your apples to apples.

Yeah I like this deal

Full boost is averaging about 4k on the dyno. Spool up characteristics are a little different on the dyno vs. the street in most cases. That is why I put up a direct comparison of pulls made with 3 other stock turbo Evos for everyone to compare against. You can see that at no point does the stock turbo come to life any sooner than any of the pulls I made tuning the Rabbit. I am including this pic of a log showing the boost vs rpm. I placed the cursor as close to 4k as I could get it for those that wanted to see the information. However, I personally believe that if you want to compare spool up characteristics on the dyno then it's better to look at the dyno sheet I posted earlier with multiple vehicles.
