darksnake Posted September 25, 2011 Report Share Posted September 25, 2011 What is the 5.4L safe max. engine hp with stock piston rods, etc...600, 650, 700? Does the 2008-2009 725 hp Super Snake use stock 5.4L or have upgraded piston rods, etc.? Link to comment Share on other sites More sharing options...
wanted2b Posted September 25, 2011 Report Share Posted September 25, 2011 I've had the same question. How far can you go before you have to go into the bottom end? Link to comment Share on other sites More sharing options...
Secondo Posted September 26, 2011 Report Share Posted September 26, 2011 All Super Snakes use the stock engine with an upgraded supercharger. Evolution Performance went over 1000+ HP on the stock long block with race fuel and turbos. Using pump 93 octane gas, I believe the max safe wheel HP is around 700-750.

I'm road course driving my 2008 and work it pretty good to max hp shift point between corners & straight aways. I should be safe with 596 rwhp, 610 rwtq, @ 700 engine hp.

Justin00Stang Posted September 30, 2011 Report Share Posted September 30, 2011 The super cobra jet, which makes over 800rwhp, is the only one that has a built motor. It seems that around 22psi combined with 750-800rwhp is the breaking point. Those that run around with 17-18psi seem to last a long time. I believe as much as 20psi may be safe too. My car makes 816rwhp on the stock bottom end with a 2.3l tvs, but it does it with only 18psi since it has cams, I don't know how long it will last.

shel-b001 Posted September 30, 2011 Report Share Posted September 30, 2011 When TS toured Romeo engine plant in 08` that very question was put to one of the engineers & he claimed the rods would stand 750 to 800 h.p Link to comment Share on other sites More sharing options...

fcettner Posted October 4, 2011 Report Share Posted October 4, 2011 +1 ^^^ 700 horses is tame enough for todays roads/conditions. Any more than that stuff wears out. Link to comment Share on other sites More sharing options...
twobjshelbys Posted October 4, 2011 Report Share Posted October 4, 2011 The target for my FGT is 700. Based on prior experience with the Shelby GT supercharger, tires will be your weak link. Above 700 and the street tires and stuff just can't keep up. Even at 700 I'm switching from the Ford F1 "Supercar" tires to Bridgestones. Link to comment Share on other sites More sharing options...

You can still run more but at the cost of longevity. Phill Link to comment Share on other sites More sharing options...
vapor08GT500 Posted October 9, 2011 Report Share Posted October 9, 2011 I have many GT500's that I have built with 750-785 RWHP with safe tunes that have held up just fine. It is all in the tune. My current GT500 is 763 RWHP on 91 oct pump CA gas with no issues and 13K miles. Drag Racing, Road Racing, and street driving, no issues. I will no do a street car past that amount as you are just playing on borrowed time. You also need a beefed up clutch (my favorite the Spec Twin SS) and wide wheels and tires to hook up. With stock tires and width, you will spin all the way to 5th gear.... Alex Link to comment Share on other sites More sharing options...
Bassaholic Posted October 9, 2011 Report Share Posted October 9, 2011 Hey Vapor what else do you do to get these cars to hook? Mines a fairly stock motor with upper and lower control arms with nitto drag radials, but I can't hook for the life of me. Either I set it up where it spins or a get to much bite and it just hops. Any other suspension changes or find a wheel that will fit so I can use a tall tire or what? Link to comment Share on other sites More sharing options...

QuietShelby Posted October 11, 2011 Report Share Posted October 11, 2011 I could have sworn that I remember seeing a video that evo had where they had a stock bottom end with there TT kit on and wanted to see the limits. I think the final number were 1016 1019 at the wheels before it blew a rod. I couldn't find it but I'm sure it's out there somewhere. Link to comment Share on other sites More sharing options...

Like Slabo siad, check out some of my builds, I use the same set-up on most builds with great results, also as wide of a wheel as possible, up to 11/3/4 wide if your trim the bumpstop brackets...

Any other suspension changes or find a wheel that will fit so I can use a tall tire or what? A quick, easy and cost-effective way to get rid of the hop and get a decent launch is to replace the control arms or bushings, install control arm relocation brackets and use a good slick or drag radial. 17" wheels are the smallest you can use with the control arm relocation brackets, 15" without (the relocation brackets can't be used with the sway bar relocation kit for the 15" wheels). Evo got over 1000+HP on stock rods with race fuel. Link to comment Share on other sites More sharing options...

garza2n4 Posted December 4, 2014 Report Share Posted December 4, 2014 What about oem fuel pump? How much can that handle before you have to upgrade? I have stock fuel pump with a BAP made by JMS.I put 52 lbs injectors and was able to produce 808 engine hp with 704 rwhp on stock TB and engine with 2.3 TVS 2.6 in pulley.

Wow I don`t know if I would want to push 1,000 H.P on stock rods , I believe the Ford engineer at theengine plant, said nothing over 800 h.p on stock rods.

2007tungstenGT500 Posted December 4, 2014 Report Share Posted December 4, 2014 You guys are brave. You all need to make a distinction between what the engine can stand right now versus in the long run. Just because you can get 800 rear wheel horsepower on some dyno today does not mean your engine can handle that kind of output permanently. If you do blow a motor, are any of you going to come back on here and admit you were wrong? I seriously doubt it. Some folks more knowledgeable than myself have already done this homework... http://www.hotrod.com/how-to/additional-how-to/hrdp-1104-what-breaks-in-2005-2011-ford-mustang/ Link to comment Share on other sites More sharing options...

garza2n4 Posted December 6, 2014 Report Share Posted December 6, 2014 Good point 2007tungstenGT500. My 11 GT500 has 16k miles and counting @808 HP. I will not be adding more HP until I change out the motor for a forged one. I think the possibility is there for it to pop but that is the case in any scenario if it's not tuned correctly.

Mines make 900 to the crank and 765 rear wheel horse power. I’m pushing about 20 to 22 boost and no problems here yet, drove it daily for about 2 years.
