OK...this car is freak'n fast. I went from maybe 250 rwhp sluggish factory tune auto, 100% stock... to a monster...scary fast... and I left Tillman's with the 3.50 pulley on... I want to make sure I get the driving thing down first before I go with the 475 rwhp at 11.50 psi....
I am very happy with the car...funny thing is... for 19 years... I have been playing around with mustangs... bit by bit adding this and that to the cars to enhance their performance... always thinking "what next?"
but now, I just went all out with ONE very important mod (blower) and there's nothing more to do to the car...
Headers...long tubes... for what 10 rwhp? for $1,500 installed? X-pipe w/ high-flow cats...$500? for how much rwhp... 5? don't need a t-body... don't need more ribs (wider belt)... or a beefier tensioner... or fuel system... relocated IAT sensor... in fact the E-force provided IAT sensor is actually two sensors... IAT and a 2 bar MAP, which I have wired into my aeroforce interceptor to monitor (electronically) boost along with my mechanical boost gauge.... Wait... there's more... using the high flow CAI from Edelbrock... don't anything there also... 90 lb/min MAF... good for 700+ rwhp...
The Tillman Eforce kit is COMPLETE!!
The engine most likely can't take any more hp, so I really got no where to go except forged internals...
Secondly, going with 3.73's wont help... 1st gear is useless as it stands w/ 3.31's... and with the 3.50 pulley, second just barely hooks now. With the 3.25 pulley, 2nd will most likely become useless at WOT.
Talking to Rob Simons, the eng/designer of the eforce, he recommends a mild set of blower cams that will enhance top end flow... and slightly reduce the boost increase and INCREASING FLOW to the engine. (sort of like unbending a straw as you drink something, the pressure is reduced before the kink and the flow increases)
Data logging on my aeroforce I see about 7 psi at 3000 rpms... 9 psi at 6000 rpms... and I saw a blip to 10 psi at 6500 rpms right before it shifted into 3rd. basically 7-9.5 psi as Chris mentioned.
Sorry to ramble on... still somewhat giddy about the car...my total investment is:
$21,650 - 07 GT w/ 8k miles (nothing like letting someone else pay for the depreciation)
~$1,200 MD state sales tax (bastards)
~$6,XXX Blower installed/tuned (cut me some slack on a "used" blower)
~$1,100 3 gauges/pillar installed (Cobalt WB and boost, and aeroforce)
$284 - SSS mufflers shipped (seem to be Borla knock-offs, but sound and look good)
Total investment - ~$31,000 for a 550 hp car w/ heated/leather seats, good handling, decent gas mileage (average 24 mpg driving home from tillmans) and killer stereo...This is far cry from the level of quality from the good ol' 5.0L days...(of which I have found memories of crushing the camaros & trans ams... and running neck & neck with the Grand Nationals...)
(happy as a clam)

But I'm sure you will get used to it. Sounds like you have a good plan for learning how to handle it though. Take it easy and good luck with it.

damn dude, that sounds friggin' ridiculous.. I am pretty sure I know which SC set up I am getting. What size tires do you have? Ever consider some fat ol, 295/45/17s and some UCA/LCAs??
that should really help you hook!
Some awesome numbers with just the blower, simply crazy if you ask me...

Congrats! I'm jealous... but it sounds like a difficult car to drive on the street. It reminds me of trying to drive with summer tires on a cold winter day in my car. A little too much gas and it was sideways. I don't know if I could live with that kind of sensitivity... kind of like driving on black ice.

It drives completely normal on the street. Mine is at 424 rwhp and unless I floor it there isnt any real control issues. you can feel it lurking in the background though. I barely chirp second but wide nitto 555's in 100 degree texas heat makes for a sticky combo. The roads literally shine from the heat softening them.

Nice numbers man, Congrats on the low investment and high output, Ive personaly put 40k into my car, But i keep changing my mind from going 
Show quaility vs 
Race ready. Kinda have both now... just need the supercharger, My 4.10's and 450RWTQ might be a fun combo off the line with some Drag Radials, Thanks for the informative post
