I have a 95 5.0 thats going to have twin turbos on it. Ive been reading that the block is only rated to 400-500 hp. Anyone know of anyway to increase the hp that it can withstand?

Aftermarket block required I believe. How much horsepower do you think you'll be making? Are building an engine or adding turbos to an old one? How many miles is on it? What heads are you using? If you're wanting super huge power and are gonna use turbos to do it, you pretty much have to start from scratch and build the motor specifically for turbo use. Starting with a new block.
Ps: no stripes

Depends on what you're doing with the car. Strictly drag, sure it might make a couple good passes as long as your tune is on point. If you need daily drive-ability with reliability then go aftermarket and blueprint the motor for Christ sakes. Stock motor with more than 480HP or so I'd be worried. Dart SHP 1200+HP, no worry. Again, as long as you have a good tune.
 
Some people might suggest a girdle, while that might seem logical. It doesn't really help the mains from splitting, more or less just holds them together while they split. The Darts are good due to thick cylinder walls, better oil flow, and four bolts on the #2, #3, and #4 mains.

Hm a girdle huh, that's a new one for me. I see the concept though, pretty much holds the "shrapnel" in?

They help spread the load caused by piston/rod deflection as the crank rotates. This is nice for you high compression solid cam types that like to turn a lot of RPM or folks who have a turbo that's builds gradually.

Torque is what breaks these blocks. Making HP very quickly. It's starts in the lifter valley and if allowed to continue proceeds right through the mains.

Not long ago main stud girdles were all the rage. Trouble was that people were using them for the wrong reasons. Drag cars need to make a lot of HP quickly. Torque... Take a small cardboard box and twist each end in opposite directions slightly. A girdle will not stop this. The thing would have to be two inches tall even to begin.

It does help keep the two halves together for sure. hehe I don't think that this was its intended purpose either. :rofl:

Stud girdles do have a purpose but it wasn't supposed to keep the block from twisting.

Wait.... I nearly forgot one of my favorite questions:

Why this specific number? What exactly are you trying to achieve?

Is that fly wheel HP or Rear Wheel HP? If you know the answer to that question then you must also know why this HP number is necessary to hit your goal.

More simply:

What do want the car to do? What are you willing to spend to make that happen?

I think maybe he's trying to beat an Accord?

Where'd you learn that?
 
Ha nah about the girdles and sht


Some trial and error, a few magazine articles, discussions here and other forums, but mostly from a white paper that accompanied the girdle that I bought from CHP many moons ago.

It's what started me into looking to see what they were actually good for. I'm pretty sure I still have the girdle. I was going to use it right up until the point where I ordered a Dart Sportsman.

Pretty sure I have a set of lifter valley girdles lying around somewhere too.

I'm gonna have to do a google image search. Were they pricey and have you heard of anyone using one recently?

I know the answer to all of the above: He's 19 yrs old.

Probably bought the $300 ebay twin turbo kit that puts the turbos through the hood.
Remember the "tornado"? The thing you put in your air intake pipe that supposedly made the air spin as it entered the throttle body there for making more power? I almost bought one when I was 16 for my 87 crx. I think that was around 1998. Gimmicks.. Sheesh
