Can't. Like you mentioned; that'd be a 3pt splitter and 3pt air dam. We covered all this a few months back in the Aero thread that EVOlutionary started; it's a freakin huge thread!
I thought about going that route, but dumping 10 of my 34pts on aero bothers me! (the last 5 being the FI penalty/equalizer).
If you wanna try to make 408 on the stocker on a lean tune, go for it. I'm not going to try it. Not trying to be a dick, but havne't you popped a few engines already?

the stock evo 8 turbo wont make 400whp, no matter what you do (at least on the dyno we use). its maxxed out around 370whp. an evo 9 turbo can do 400whp on our dyno though, but it takes every trick in the book (to many points to make it worth it, at least IMO. i've 398whp on the dyno, stock 9 turbo, no cams before, but it had ported intake manifold, throttlebody, exhaust manifold, and pipes, exhaust etc... on e85.

I didn't say lean, I said aggressive. The Evo has 92k miles on it, and other than a bad head gasket it's never failed. STi is the trouble maker when it comes to engines. 4G63's are just tanks. We're no where near their limit with what we're trying to accomplish.
Are you talking DJ or Mustang numbers here? I made 380 something on a dynojet, Evo 8 turbo, e85. And according to most people in the tuning section of the forums I can be making a lot more.

380whp on a dynojet with e85 sounds about right. , i believe you can make more too. a lot more? depends on what mods you have. your racing TTA too? where are all your points at?

Boomn29, are you running injectors and a walbro 255 fuel pump? your blog says no. and from my testing you'll be maxxed out around 310-320whp on our dyno on pump gas (race gas a little more due to timing only, but no more boost because the pump is weak). those 2 points are worth 30-40whp at least on our dyno by running e85, and definately 40-50ftlb of torque.
23,500 miles on the car, 60+ track days.

Do ambient temps really have that much affect on brakes? Rotors get up to what temps, 1,000 something degrees? The percentage difference between ambient temps at 40 degrees and double that isn't very much at all when rotors are getting up to 1,000+. I could be completely wrong, but it's something to ponder. 
TTA and TTS have the exact same weight/power ratio limits.

i always refer to numbers on a mustang dyno, cause thats what we have around here, and thats what we use when we dyno tune.

As the car sits:
** +14
turbo +5
intake +1
exhaust +2
exh mani +2
cat +1
cams +6
fmic +4
mbc +4
fuel +2
springs +2
r6 +10
245 -1
total 52
I'd at least get sways and a real set of springs for the stock struts before I tried this. I'm also getting a built head, so I'd probably ditch the pnp exhaust manifold
Huh, didn't know you were running the stock pump and injectors. Do you know what IDC you're hitting?

Ah, okay. I think I have enough done to be making over 400 whp safely. I'm not really running TTA anymore. I use to TT an STi which I'm now focusing more on racing in ST-2. I got screwed on my reclass with the STi, and have always said it's unfair they're based the same as an Evo 9 when the Evo is so much more capable. My street car is an Evo 8 which I've tracked a couple times before, and am considering going after my old STi TTA times just to see if I can do it.

so we have to get it dynoed now. most likely we are going to take the head off and go for more grip because hes most likely over the power limit.

I'm taking it to Kans on Saturday to see exactly what power I'm making and will report back. I really want to keep the head on the car if I could, so much work..

TxEvo8 has almost that exact setup on his car. even has a ported big valve head on it for +6. although he was running NT-01 tires, and had coilovers. the other guys in the class were complaining because he was dusting everyone on the straights so we have to get it dynoed now. most likely we are going to take the head off and go for more grip because hes most likely over the power limit.

Some of this can be attributed to people like me who will have to run in TTS (points) but are not fully TTS prepped. I have some 'stupid' points that would cost $$$$ to reverse. Things like the Evo 8 3-4 gears in my tranny, 3 points. My JDM rear bumper will get hit with diffuser points, and so on.

Jim,
I don't think you'd get dinged for diffuser points since there is (may have to re-read but am 99% sure) no where in the rules that it says you can't swap parts with a different demostic market's car of the same model year, especially stock exterior body parts. Correct me if I am wrong.
