Mod's are in the sig for the 2006 GT. The tune is a 91 octane. Will a 93 octane make a difference?
I'm hoping for about 290 rwhp on a Dynojet.

OK, made 292 RWHP at 6100 rpm's and 307 RWTQ at 4500 rpm's. So right about where it probably should be.
I'm think about adding new coil packs (Accel) and an OR/x pipe with a 93 octane tune. That would hopefully get me over 300 RWHP.
Went to the track after the dyno session, that was not good...
Don't waste your money on coil packs. If anything, I'd say take the money you would have spent on the coil's and get yourself gears. If you have gears, save for a blower. Coils would be useless on a N/A car.
A lot of people say the factory exhaust is free flowing, but it actually has some restrictions. The restrictions are primarily in the headers and h-pipe. The next time you are under your car take a look at the welds on the catalytic converters. 2.25 inch pipe is welded between the converters and the rest of the 2.5 inch h-pipe. The pipe is also crushed on the passenger side where the 1st O2 bung is welded in. As far as teh headers go the exit from the factory exhaust manifolds are only 2 inches. So you can gain some power replacing either one. I have some low quality pictures I'll try to post later. The h-pipe is also only functional to around 3000rpm. The x-pipe is worth some power because it is able to mix exhaust flow at high rpms.
Hot Rod magazine picked up 9.9hp and 8.9 lb/ft peak with a BBK X-pipe. I think there is a link on the BBK homepage.
Also if your looking for some more power:
MMFF magazine also released a video (came with the magazine) on a 06 GT buildup in Dec. 06. They picked up 8hp peak from a BBK 62mm TB (gains were also good across the range).
You could also consider some headers. Short tubes will only give a few peak hp, though they are good for power down low (see mustang monthly article on BBK header install). But if you want good gains at peak you should go with long tube headers. Consider both before buying an X-pipe as the X-pipes are specific to shorty or long-tubes.
I rechecked the calculations and it is 110.3 mph. And given that I made a mistake earlier, it is possible that I made another one (although I triple checked this time).Redfire GT: Wow, 111 MPH is impressive. What altitude are you at?
380 flywheel hp is way off with the mods you described...
