It's not typical to find someone running the same boost for a long period. Because it's so addicting, you want a little more here and there.
I started with nitrous at 5K miles. Went TT at 12K, now at 25K.
2005 100hp NOS 5177
2006 TTiX 7psi, 530rwhp
2006 TTiX 9psi, 560rwhp OEM cats, Ti mufflers
2007 TTiX 11psi 650-660rwhp OEM cats, Borla mufflers + meth, 135-138mph trap
2008 TTiX 13+psi no cats, ???rwhp 142mph trap
Yes the success is alot from the tune, some common sense and probably a little luck. Mine has complete stock long block and no breakage. I did have to catch the cam bolts that almost backed out after boosting, and put em back with loc-tite. I've had plenty of driveline issues.

Yes it had a wierd knock and a limp after hitting 18PSI for a short burst on the way to the track. When I got to the track I turned it down to 13psi and made a pass knock wasn't any louder so I turned it up to 16psi and it threw 3 rods at 1/2 track. The knock I was hearing was the pistons hitting the crankshaft counter weights due to the shortend rods. The other 5 rods that were still in the engine were all bent about the same amount.

Type Of Forced Induction: Procharger D1SC
Boost Amount / RWHP: 8 lbs / 475 (Mustang dyno)
Miles on the car when FI installed: 48000
Miles ran since FI installed: 6000
Bone stock '01 long block.
Only thing I have wrecked so far is the stock clutch. That went out at about 4500 miles. Hopefully the rear end will last long enough before putting a 9" in it.

- Type of Forced Induction: STS rear mount

- Miles on the car when FI installed: 61k
- Miles ran since FI has been on the car: 14k, 2 years
stock bottom end, stock heads w/ dual springs... aftermarket cam
keeping my fingers crossed!!
just curious, but has anyone had problems with pushing coolant/heads lifting with low boost(5-8psi) and stock heads/bolts?

When I first bought my car new I drove it straight home and installed the D1sc blower kit that was waiting at home. I read on this site for two years before I did anything. OK D1sc at first 10# boost and a m15 meth jet at 612rw and 519tq installed at 26 miles. Later I upped the boost to 12# and added a fmic and another meth jet which gave me 651rw 561tq and it now has 11453 miles. I have not broken anything, I street race a little but from a roll only, and If I think I might see some people and its hot out and its the weekend I will get some 100 octane.

I guess a lot of these combinations are mercy to the condition of the block in the first place. For instance, my car has about 90k on it. I wouldn't attempt to boost my stock bottom end. Some cars with say 20k on the clock are basically "brand new". The problem then comes up when greed outweighs reality and going from say ~8 to ~10 psi could mean the difference in power to make a stock engine have failure. Some cars might survive on 12psi whereas some will fail at 6psi. It's all relative. When I end up going forced induction, I am just going to wait until I can build a motor. If money permits, someone will build it for me. Otherwise I will learn to do it myself.
