How does this thing not blow up?

621rwhp, 464rwtq
pegged maf at 6600
novi 2000, 15 psi
13 degrees of timing
11.4 a/f fading to 10.9 at 7500 rpm redline.

That's a stock bottom-end 99 Snake running 15psi with no I/C.
How much boost/HP will the 99/01 4V hold?
I was under the impression that these things like to blow a big hole in the block on big boost.

And look at the difference between these two!

SHM? Shortblock (forged??), ported top-end, low boost, stock cats. 405whp

1999 AEW Mustang (used to be a 99 GT)
99 SHM short block 4v
FRPP headers
ported heads and manifold
stock GT exhaust w/ 6 cats.
Vortech SC-Trim with stock pulley. (10 pounds on dyno; 11 on street)
Vortech Aftercooler

Stock longblock, FUEL!, same boost...470whp!

2001 Mustang Cobra V1-SC ~9psi
Aviator Fuel Pump
AFM powerpipe
pro-m 80mm maf
42#
magnaflow catback
magnaflow x-pipe
SCT by jms
470/412 i think it was running 14 degrees of timing
still working out JMS kinks though

Its all in the tuning and the first one you posted (621rwhp,464rwtq) is not stock. Its a built motor with cams and ported intake.

Quadcammer's setup is not the stock longblock. It's forged (he just doesn't have that in his sig).

He is running a built block with 8.5 pistons.
