I'm a bit a late on making this thread I guess, but this should about wrap it up for now. With any updates in the future.
The Beginning;
In April I was drilling out a broken turbo stud when a drill bit must have snapped and a chunk flew into the head (even though we had the ports covered). Needless to say, it pretty much did work on everything.
Towed the car to DB, talked with shane for a bit, and made this plan.
(previous was stock motor, stock IX turbo, e85, and 336hp.)
New set-up;
Short block
Manley Platinum 9:1 pistons (20 over)
Manley I-beam "turbo tuff" rods
Balance shaft removal
Stock crank.
Head
L19 Head studs
Supertech 1mm over Intake valves
Supertech dual valve springs
DB Stage 3 Head porting
GSC S3 cams
Fuel
Walbro 255 (already been in car for.. 40k miles)
Boost-a-pump (40amp)
FIC Bluemax 1450's
e85
Turbo/Intercooler etc
FP Black (thanks Trevor!)
eBay special Exhaust manifold.
Perrin knock off intercooler (already had it, "OBX" brand)
Tial bov. (Thanks Tom!)
Short rout piping. (already had)
DBperformance MBC.
Misc.
Speed Density Conversion
Emissions crap gone
ACT 6-puck sprung disc (already had PP)
Shane.
After a few months, I got to pick up the car and do some break in. I was super impressed with how smooth the car drove consider the recent mods. I think a little credit goes to Speed Density, and a LOT of credit goes to Shane.
After I got 4XX miles on it I went back for the final tune, here's how the night went down;
1st pull, BP-style oil leak from the dipstick hole. (dipstick landed on the floor about 4-5 feet away from the car I think.)
A good amount of pulls later, I hit 449 and it appeared I was running out of fuel. (almost 13:1 toward redline) I was pretty okay with this, it's only a SINGLE 255. Nope, Boost a pump wasn't working. Next pull we had TONS of fuel.
A good amount of pulls later, we had hit 501, then 516. Again it seemed we were running out of fuel on the top end. We decided to mod the fuel pump.
A few pulls later, running 36psi(peak), and solid safe AFR's we hit 529 and decided to call it a night. I was super pumped!!
The car is now super fun to drive. I love it, it's solid. Very well put together by DB Performance. Shane, Danny, and the rest of the crew do one helluva job. Videos, and graphs to follow.
529hp pull on the dyno;

(Scheides recorded it, and I believed pulled his groin trying to hold up the camera. Tehe, hope he's feeling alright!)

I *really* want to get another BCS so we can try and hold a bit more up top, there seems to be more power waiting up there.

Next thing to take care of, bad master cylinder.
