2008 Evo X GSR - Moore Automotive Tuned 2.0L 7675 - 1022whp/636wtq
2008 Evo X GSR
Fuel: E85
Mods: 2.0L Darton sleeved block
Manley Turbo Tough rods
Manley Platinum Series pistons
ACL Race main and rod bearings
Cosworth headgasket
ARP 625+ head studs
Ported head
Ferrea +1mm valves
GSC beehive valve springs
Kelford 214C cams
Ignition Projects coils
Ignition Projects Plasma Lift ignition box
Stock spark plugs
ID2000's
Boost Therapy large plenum intake manifold
Boost Therapy 75mm throttle body
Boost Therapy 1000whp fuel system
Boost Therapy sidewinder turbo manifold
Precision 7675 T4 twin scroll turbo
TurboSmart 40mm wastegates
4" downpipe
4" Aluminum exhaust
Omni 4 bar MAP
Speed Density (MAP only) tune by Chris@Moore Automotive
These were 4th gear runs with a 4.30 FDR so mph goes out to 155
Boost was really at 44psi due to only having an Omni 4 bar on it (our dyno boost sensor isn't scaled 100% correctly), didn't want to trip the MAP high voltage code since this is speed density tuned. I want to try putting an AEM 5 bar on it and going a little higher. Also, I'm not quite sure why we were having a boost dip at 8200 (which you can see affected the power there) and then coming back up. We're supposed to be going to the track later this week, so I'll see if it's doing the same thing off the dyno or if it was a dyno load thing causing it. Although now I'm thinking it may be a valve spring issue causing it. In any case, all the Boost Therapy prototype parts listed on this car will be in production soon and available through Moore Automotive.

Congrats man
Insane numbers. I was having this issue with boost dips as well. Sometimes it dips and sometimes it stay flat. I noticed the throttle closes for that time and opens back. What did your logs tell you?

Drove the car yesterday and switch the map to e85 to its full potential and to get my itch fix before i head out to sea for sea trials and to see if driving it around town will be an issue but surprisingly this car drive like stock, made some pulls on it and it was super amazing. That final drive is just awesome...power seems like its never-ending. I have a good friend of mine who has my 6466 setup on his car and has 800+hp on it and i asked him to get some video but he failed to get a good one cause he got suck into the seat and he told me, he has found a new definition of fast...lol... the car will be on richmond dragway again this weekend for testing after the fact builder and chris found the issue that we have on the shoot-out.

i just noticed you guys are using beehive valve springs ? if im not mistaken those have a rev limit and shouldnt go past 8500 let alone 9k.. that might be your problem you might be starting to float a valve maybe? or its having trouble keeping up.. i wouldn't doubt it im doing a similar build but i went with dual valve springs which we swapped out too last month and i have a sleeved 2.2 by bore but id be happy with 850hp not lookin to break anything else ... for the third time ... lol

Great Build Car seems to run flawless this is a question for both MA and Boost Therapy most Evo Guys wouldn't dare to touch a turbo that size,but you guys not only made it work but made it spool how is that? I remember when the EVOX 1st released with the 4b11 people say it was very similar to the honda K series which uses these large turbos like you are using to run keep 9 and 8 second passes revving large turbos fast was it the side winder manifold that helped like the honda guys used?
