i am picking up a set of forged piston for my Ls/Vtec. i wanted to get rods too. one of my buddy told me about shotpeening the rods. How relible is it?, How much h/p can the rods handle? and will it hold a 100 shot of NOS?.

Thanks

Danny

 

What kind of rods?

 

um stock ones

i would get some upgraded ones ...
not worth the risk

shotpeening is a band aid for weak rods

 

the rods are stock ls

 

For all motor the shot peened rods will work great, but if you are adding a 100shot to mix, I would go ahead and find yourself some Eagles.

 

so the rods wont hold a hogh shot of nos

 

I think shotpeening just help keep stress cracks from starting. It doesn't actually strenthen the rod if I understand it right. (And I may not.)

 

Shotpeening a cold working metal treatment process. Basically it is bombarding the surface of the metal with tiny round carbon steel spheres.

Most material failures in metal are due to tensile stresses on the surface. When you shot peen the metal, it introduces compressive stresses to the surface. The now compressively stressed surface metal serves to deter any tensile and corrosion stress failures. It increases the resistance to surface stress cracking, and also resists the growth of any surface stress cracking.

 

This is off the subject but, won't forged pistons rip apart the stock sleeves? Or is he running on Dartons or something?

 

why go cheap. engine is open. go for some nice crower rods.

 

i just wanted to save some money to put towards the head. and the nos is not for sure. if i get it il use it maybe one and a while not on it all the time. i want the motor to stay reliable it a every day driving car.

 

Upgrade your rod bolts too-ARP.

 

stock ls rods are good for 300 hp, if you shotpeen them, why not go ahead and beam polish them too, arp rod bolts would be a must have regardless

I totally agree, Eagles are inexpensive and will hold up under the extra F/I forces a lot better...

 

i hear mixed stuff about eagle rod some say there good and some say there garbage.will the sieze.

thanks

 

eagles are going in mine...

they were also in my last motor

i say eagles

I heard the same. Thats why I'm deciding to either get manley or crower rods

 

Eagles will work great, I've personally have never seen/heard of any problems with them... It's up to you to make sure your oil clearances are within spec... I will just about always take Crower over Eagle but I was trying to keep the price down... I love the 4340 Steel Billet connecting rods... If your choice was between Eagles and Crower Econo Billets I would go with the Eagles... Latez

 

someone on this site is selling crowers brand new for like 550+
