I don't know, I'm not arguing the use of 42# injectors if you use all 18psi, but I don't know if you will use that much to generate only 380 wHP.
By the way, I'm already well over 400 HP at the crank in my machine. Remember, I set down 303 wHP with only 5.75psi and my stock 60mm TB at SF on 91 octane fuel.
I'm running between 8-8.5psi now with a 70mm throttlebody and 93 octane gas daily. Calculations are 415 crank HP with conservative estimates, but if the percentages don't lie then 420+ crank is more like it.
I expect MUCH higher if you are running 15-18#'s of boost. Oh for the joy of having our two cars in the same place, one in the 1st and one in the 3rd lane of a 3 lane road and some sucker with a V8 or a SRT-4 (had to throw the last car in there) in the middle!

Intercooler: That sounds like the same intercooler dimensions to me. I know it works great for me.

Exhaust sizing: I'm worried that you may have sized your exhaust housing a little on the small side too. I don't know what your boost threshold is supposed to be but I'm guessing your looking for full boost by 3500 rpm or so.
Will this choke out your exhaust at high rpm and high boost?
You could be looking at as much as 730 CFM at 7000 rpm and 18psi. That is a lot of airflow my friend.
I'm guessing you may make your HP mark, but you will have much higher midrange torque than anyone we've seen so far!! I fear that the power may drop off though before redline and peak numbers may not be as high as they could be with that setup.
However, on further speculation, you are probably reaching for boost earlier since your compression is only 8.5:1 and the engine will be a dog before boost comes on. Probably a good compromise I guess.

No matter what happens, I'm rooting for you!

Yeah, like i said, i dont really know what to expect as far as hp goes. Im going with lower compression, but a higher boost, so we'll see how it reacts. And yes, that was one of the reasons, i did go with this exhaust trim. You figure im not going to be running 18 psi daily LOL! I do want some low end power. Right now, I just want it running and running properly! Hopefully I dont run into any problems.
