5 ringlands gone in about a month aka 1000 miles of driving.

- P1sc kit
- 8 PSI
- Installed everything in sig ~79k
- ~1,000-2000 miles on it since the build
- Nothing broke as of yet

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.

APS twins, 10-11 psi with meth, went on 61k, about 65k now. 585 rwhp. Nothing broke yet.

X2! I went 10.59, and have run 130+ MPH in my 5000LB 2003 4x4 at 5000' elevation with a stock bottom end 01 6.0L. After the 10.59 run @13psi in Las vegas I turned the boost up to 16psi and the rods failed. Bearings, and even #7 piston were still in good shape.
-01 6.0L
-Hand ported 317's stock valves
-ARP hesd studs, GM gaskets
-Trick T76 @14~15PSI
-91 octaine+ Meth

The rods all looked like this

Holy crap. I have never seen a rod bent that way. How did you know the rod failed? Was it knocking or what?

Yes it had a wierd knock and a limp after hitting 18PSI for a short burst on the way to the track:devil:. 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.

LilJayV10 01-30-2009 02:00 AM

Damn those are good carnage pics! That is a lot of weight to push down the track. No wonder the rods said, "Screw it, we've had enough...I'm out!"

Sweet ride.

Thank's! Yah I think the weight, and the drive PSI I have up here at 7000' elv taxes an engine. The wastegate is completly closed to make 14~15psi up here. Las vegas is low elevation to me:jest:

Only ERO's 01-30-2009 10:13 AM

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.

z28boy 01-30-2009 11:15 AM

Mods are in my sig seems to still be running strong,also has meth in it to just incase.

RooRnZ28 01-30-2009 11:32 AM

- Type of Forced Induction: STS rear mount
- Boost Amount / RWHP: 5-8psi, 500 rwhp
- 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?

BOONE 01-30-2009 04:49 PM

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.

White.Lightning 01-31-2009 08:25 AM

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.

ya thats a good idea with the built motor i just done the stage 2 hp performance turbo kit on mine 67mm 9psi made 548hp 618 tq on a dyno jet dyno and i drove the car maybe 800 miles i did the arp 2000 rod bolts and head bolts like they say to do but rod bolts dont help pistons :bang::bang:

00Z-28Maro 01-31-2009 11:18 AM

- Type of Forced Induction: PTS kit w/67mm
- Boost Amount / RWHP: 7psi, 507rwhp through T56(was running 8psi after changing to th400)
- Miles on the car when FI installed: 35k
- Miles ran since FI has been on the car: 15k, 2 years

Stock bottom end with an aftermarket cam. Stock heads with upgraded valve springs. Engine ran fine until I went to a 78mm. Car hit 11psi on the dyno and spun a rod bearing last Tuesday.

DD966 01-31-2009 03:19 PM

D1SC
7lbs. of boost + cam & bolt-ons = 500hp
29k mi. when installed two years ago
39kmi. now

Completely stock bottom end that has never gone 3000 miles without an oil change. Good gas mileage, and runs like stock too.

Now that kicks ass. Buy it, drive and home and put a blower on it. :pimp:
