Should be seeing another dyno soon an with an Adaptronic E1280S. Owner is working on a new fuel injection manifold with 4 90mm throttle bodies

I have used them, but its been a good 6 years or so. I would contact Motec

Clive,  

          A version 12 firmware update will be out for the ecu this week. It has a few new features you might be interested in like advanced engine protection features. Congrats on driving the car btw!

Lastly I am curious why it took 7 hours to create a running base map? Not knocking anyhow, but in my experience you can have a car up and running from scratch in under 10 minutes using the VE tuning. Was it just a matter of trigger settings?

Looks good! Sorry if I missed any emails, wasn\'t intentional!

I do have one question for you about the return style fuel system. Are you just using one fuel tank? The factory fuel pressure regulator siphons from the other tank.

Sounds like a lot of fun

Unless you plan on driving on drag radials/slicks with an upgraded tranny/diff/halfshafts etc there is no reason to go much bigger than above turbo for street use. @ 25psi you will need 335 tires to hook up.

That will work extremely well( except for the wastegate location). That is pretty much exactly how I build most of our FD turbo manifolds..

That w/g position is going to creep like a maniac! Trust me I\'ve built so many manifolds I can\'t remember them all. W/G runners need to be in the direction of flow, not at right angles. If you are going to run at right angles you will need dual gates. I even had a single 60mm creep on me designed similar to what you have( had a bigger collector before flange even, which does help).

By splitting the centre exhaust into 2, One to the front rotors exhaust and one to the rear rotors exhaust.

I think cummins have done a triple scroll exhaust housing for one of their turbos but it is huge and wouldn\'t fit in a car. I will try find the pictures tonight of them as I\'m on iPhone at the moment

Can\'t say I\'ve done that, but probably a waste of time. There is so much exhaust energy on a well built 20b that it really doesn\'t matter. All you need to do is keep the bends gentle, and don\'t use a collector that has bad entrance angles.

It would be best to tell us which brand turbo you are looking at...

GT4294R with a 1.0 housings is what you are after from Garrett.. A Q trim 1.15 with a 67mm wheel, and open 60mm wastegate with 4" exhaust would work too

ACT clutch will be fine, I\'ve made over 440ft lbs of torque with one. For drag racing a twin-plate would be ideal. 280lph fuel pump isn\'t enough for 550hp, nor are 1680cc injectors. I would get the ID2000s(2200cc) and stock primaries. You are talking about 550rwhp, correct, and not 550BHP? I assume rwhp since you are using such a large turbo, be silly to run it at 550BHP...

Water injection does work great, but you need a WELL built system if you are going to run high boost...

I don\'t know the BW series that well. Sounds like it should be able to do 450rwhp with those compressor specs. You just want to run a bigger turbine a/r with the bridge to let it breath where it wants to make power. Why are you running a bridge for such low power levels anyhow? When you say 450rwhp what kind of fuel consumption is that? To me this is the easiest way to compare power levels, as dynos read all over the place. That dyno is the only one in town I trust, and yes its 491rwhp, 22 psi streetport, TD61( gt35R P trim), dual walbros, 550/2200cc @ 77 percent.
