Another E85 Evo 10
2008 Evo 10 GSR
Mods:
Custom catback with neck down under the rear of the car (no rearward visable muffler)
Test pipe
Stock downpipe
Harmon intake
DW 1000cc injectors
Walbro fuelpump
Inline fuel filter
Crushed OEM BOV
GST Boost pill
GST Custom dyno tune
E85
346whp / 369wtq
Pretty good power with not many mods. I think there might be a slight boost leak somewhere so there might be some more to gain after finding that.
For reference on our dyno:
Stock 03/04 evo = 190-210whp
Stock 05 evo = 210-215whp
Stock 06 evo = 220-230whp
Stock 08 evo = 215-230whp
Stock 09 Ralliart = 190-199whp

First I have to thank Bryan for making another happy customer. His skill and customer service are as good as it gets. He put up with all my questions and went out of his way to make sure I was happy.
When I bought this car I was very dissapointed with the stock power. I almost passed on the car because of the stock power. Now with only Harmon intake, custom cat back which consits of 3" pipe with a borla XR1 Bullet muffler with turn down, E85 and UR test pipe I am making the same amount of power of my last stock C5 Z06 and more TQ. The car went from slow to struggling to maintain grip on all four tires. This is one of the funnest cars I have ever owned. If any one is on the fence with a X because of the stock power output, pull the trigger you wont be dissapointed. Now I cant wait to upgrade the turbo.

Very nice. How much boost? I really would like to get this done but the closest E85 pump is about 35 miles away. Sorry to hijack but, does anyone know if there is a way to purchase E85 in large quantities (i.e. 55 gallon drums)?

Great numbers especially considering you didn't go with an aftermarket O2 housing pipe. That would have added another $600 to the cost factoring in parts plus install. I wonder how much hp extra it would have made w/ the aftermarket 02 housing pipe.
