Brandon, a long time customer brought his beast back down this weekend for a retune on e85 and I thought it might interest some of you to see the cars progression through various setups:

Owner: Brandon
Username: tsurugi-san
Location: Arkansas
2006 EVO9 MR

up first:
FP Green
93 octane
28 psi
Cosworth cams
PTE 780cc injectors
tbe, 02, ported mani and tb
FMIC
DLL 389hp/367tq (below is the only chart I could find)




Changes:
FP Red
91 octane
30 psi
Buschur 2.0 and Stage III head
Summer Heat
DLL 395hp/356tq





Changes:
e85
39psi
twin walbros with pressure relief disabled
PTE 1200cc injectors
IDC 82%
DLL 522hp/473tq

91oct 30psi vs e85 39psi



I need to talk to Brandon about the exhaust particulars, I can't remember if he had a test pipe or high flow cat. I also wonder if a cam change would make an improvement. Regardless, it's one hell of a quick car...power everywhere. Lots of fun to ride in.

 

i have a question after looking at this. At what point is twin walbro dual fuel pump needed??? 600whp less or more or what?? also they say you need double pumper and 1200cc injectors to run e85 is it possible to run it without that stuff just for testing say single walbro and 1000cc injectors

 

when discussing fuel supply you must first lay down your hp goal and fuel of choice in order to make a decision.

with 93 octane a single walbro and 1000cc injectors is good for 500awhp for example, above that, it's time to do twin pumps. e85 requires about 25% more volume to make the same power as 93 octane so the fuel system would need to be more robust.

 

do i need twin pump setup then?? sounds like ill be handicapping myself to not get to 530-550 with my elaborate setup??

 

Nice numbers. I am impressed with the spool.

 

I suspect you'll be close...I'd go with twin pumps just in case...it sure would stink to have to halt the tuning process and do it again at a later date

 

AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH HHHHHHHHHHHHHHHH im aggrivated now lol now have to add a system to the list thats like another 500 i got to spend im putting that last on the list getting important things out the way . who besides AMS makes oiler cooler replacements? I want one of those to put on this brand new motor

 

Mitsubishi does, the oem one works great lol

 

the oem one is 720 i already talked to russell lol. Ams is only 512 those are shipped prices and he even told me man i would go with the ams version. lol im trying to keep it all new i dont want to use anything from the orginal motor thats how hard core i am about another issues happening to me with this used motor no more my friend

 

understandable...I re-used my stock one since the stock shorty/head was perfectly fine when I pulled it after many miles at 500+awhp for what it's worth.

 

so what kind of fuel economy are you guys getting on e85. this is great for power if your a weekend warrior but if you daily drive what kind of mpg would you expect

 

whoa!!! impressive w/ the RED on e85! yikes...

 

thats one crazy powerband , looks good man

 

nice job

 

I am averaging 15mpg with only city driving and the few races on the weekends with reaming in between. This is at 760WHP and some aggressive cams that dont get the best fuel mileage haha. Im also maxing out 1450cc injectors... That's using a lot of fuel I think if i did some tweaks to my map and did just a hwy mpg test i think i can get 20mpg or so...
