Check out this link, A Procharger w 15lbs boost. w/nos and a stock bottom end.
I'm supprised it lasted the run on the dyno; never mind the pass down the track.

Hey...does that screw up your warranty???

 

Well, we now know it'll hold up to that kind of power. As Justin stated in that thread, it's a matter of how long and that's what he intends to find out.

 

I'm glad he is doing this, I'm planning on adding a procharger this winter. I would love to know where the breaking point is before hand.

 

Wow!
That's mind blowing to me with that engine.

 

If this holds up for any substantial amount of time, even a week, whoever said 450rwhp on the stock block is gonna get a beating from me.

 

No kidding! And this after we've heard that 8 psi is the max the stock internals can take. Apparently, these 3V's are stronger than most give them credit for.

I, for one, don't have the courage to be the first to try something like this, so I have to tip my hat to those that do. But it is things like this that help me to decide what to do (or not do) to my car. Many thanks to all of you who blaze the trail!

 

Wow!!

Wonder what all the naysayers from last year are thinking... :worship:

 

I can see a three piece crankshaft in a very short time. He will not be rolling on and I wonder if he will let anyone know when he blows it.

 

MM&FF did an article in the last issue with a blown 05 gt stock internals 535 rwhp and they thought they could get 600 rwhp out of it if it were not for the stock flywheel and clutch could not hold up to the 535 even. Wait till the turbo kits are done you will see 15 lb kits making 600 rwhp easy and 8lb kits making almost 500 rwhp (with full kit "exhaust, intake, headers, computer)

 

and this...

600 HP Supercharged 2005 Mustang GT

Sean Hyland and the crew at SHM have just completed a prototype build for Vitesse Autosport of Denver. This 2005 GT dyno tested at 518 RWHP, that's over 600hp at the flywheel-on 94 octane pump fuel! The SHM built engine includes a 1999 Cobra aluminum block for durability, forged steel crankshaft, forged steel crankshaft, forged steel connecting rods, forged aluminum pistons, ARP main and head studs, ported cylinder heads. The ATI D1SC supercharger with a custom SHM intercooler, is only putting out 12 psi boost to achieve this impressive power output.
SHM replaced the stock 5 speed transmission with a Tremec TKO 600 transmission, knowing full well, that there was no chance the stock transmission would survive long behind 600 hp. SHM have developed a remote gear change mechanism to locate the shifter in the correct position in the 2005 mustang, and we have adapted a hydraulic throwout bearing assembly to the TKO 600, to be compatible with the hydraulic clutch which comes stock in 2005 Mustang. We also designed and built a new transmission crossmember and mount, and a new driveshaft assembly in order to complete the installation. The result looks like it came from factory, and the shift quality is great. Backing up the transmission is an aluminum flywheel, HD pressure plate and HD 26 spline clutch disc.

The rest of the Vitesse Mustang features Brembo 14 inch front brakes with 4 pot calipers, 18x9.5 SSR Wheels, 275/35/18 Toyo RA1 tires, SHM sport springs, HD front and rear anti roll bar, Steeda adjustable panhard bar and billet lower control arms, strut brace, bump steer kit, raised ball joints, JBA long tube headers and H pipe, Magnaflow mufflers, SHM aluminum 3 core radiator, custom hood, front splitter and rear spoiler. The car is also outfitted with a HD limited slip differential, and 4.10 ratio ring and pinion.
Beginning June 10th, Vitesse will be testing the car on the Players Run, a race between Seattle and Las Vegas, running times segments at many race tracks on the west coast.


oh... just noticed no stock internals oh well ... still cool

 

I'm guessing this engine is on borrowed time, especially at 6800 rpm. Just because it can survive a couple of dyno pulls does not prove long-term reliability. Ford and Saleen use a forged crank at this power level. I'm sure you can get a great deal on this engine in a few days.

 

I've got a Vortech with aftercooler in the mail. What can I expect at the wheels? Can I get more out it with headers?

 

cool, I'm pretty sure that sometime last year many thought this engine couldn't be blown at all.

 

Just the fact that it lasted a few pulls is amazing considering we were hearing mid 400's and you would start having problems.

 

Kudos to him for doing it!

Time will tell all as far as what this car can do and can't do, and I have plenty of time

 

I was there at KCIR when Justin was running. He and his crew spent about 8 hours on the dyno from the previous night tuning the car. It wasn't just a "few" pulls as far as I was told. He had trouble early in the day running mostly high 11's and low 12's but I believe he got it close to the 10's by the end of the event. He told me that he did not use the nitrous during any pass at the NMRA event. I have been following his car and supercharger for a little while to plan for my upgrades. His car looks great and runs pretty well too. It is my understanding that he is running 39# injectors that were take-offs from an 03 or 04 Cobra, and a fuel pump boost module (not Kenne Bell) and currently is running too rich with the boost.

 

While I dont believe that the internal engine will last long with this kind of output, it just goes to show it's a lot stonger then EVERYONE though only a few months ago.


P.S. --Thanks for the added info Derek!

 

It'll be a heck of a show when it finally does go though won't it!!! It'll be interesting to hear that story whenever that point comes.

 

Hey ZeroK,

I'm not an expert. I usually just add the the psi of the kit to 14.7 and divide it by 14.7. I'll multiply that number times the base horsepower. So if its a 8 psi kit, (14.7+8)/14.7=1.54. So 300HP times 1.54 = 463 or 463 horsepower. This is a decent wag, maybe within 20 HP. I'm guessing 420 RWHP for your car if its a 8 psi kit. I've only used header once on a different car. I think headers will help you because Ford upgraded the manifolds on the Cobra. Hope this helps. Where's Swindon at? I was stationed at Lakenheath for a few years.
