You are just paying for a name when you go with anything Greddy.

 

I don't plan on runnin anything over 400whp so I'll probably stick to OEM. I'm at ~53k. But it's good to not hear anything about random catastrophic belt failures.

 

it isnt 1990 and belts are a little different then there were back then

 

The oem belt can handle up to 600hp so I have heard

 

Learn me here. What does HP have to do with the timing belt? The engine still spins at the same rpm speeds whether you have 100HP or 1000HP.

 

The more HP you have the faster you go through those RPM's though.

A stock Evo takes X amount of time from 3000k to 7500k, A modified Evo will go from 3000k to 7500k faster.

 

That will have little or no effect on the timing belt. If it did people would break their timing belts while free-revving the engines. A bigger issue will by typical redline. The timing belt will be under much more stress at 10,000 RPM than it will at 7500 RPM.

 

I ahve a feeling the timing belt is limited by high torque not high HP. The torque can cause the belt to stretch or skip a tooth.

 

im gonna have to agree with this guy

 

dynoflash is running the OEM timing belt and has over 950 awhp.

i have close to 600 on race gas and OEM is the way to go

 

A fresh timing belt is not going to stretch for anything, or any amount of hp. Now an old one that is worn, cracked, or just plain old.......might be cause for concern.

 

I skipped the 120,000 mile belt change on my 91 Talon a few years back. Well I parked the car on a hill and used the engine/tranny to hold most of the weight of the car. When I went to start it, the belt snapped. It was at 160,000 mile. Not sure if the two were related but I think it was. Who knows how long the belt would have lasted if I didnt do that. The car was wrecked in the passenger side rear and the rest of the car was in ok shape. It was my beater that I delivered pizza in during college so it retired to a junk yard. I put almost 70,000 miles on the car in 2 years. Boy do I miss it.

 

Not to be off topic, but coming from 4 years driving 2 LS1 Camaros;

A lot of guys when upgrading went with these Rollmaster Timing Chain kits.. some with DUAL timing chain kits. It turned out that most of them stretched and caused more problems than a simple LS2 OEM chain.

So taking from that experience, I will be using OEM.

 

I'm at 51k miles on my VIII. I will probably start thinking about ordering the 60k tune up kit pretty soon. I plan on going with the OEM belt and other parts.

 

Hate to continue off topic, but I'm coming from a LT1 and a 500rwhp LS1 SS so I can definately relate to what your saying with the timing chains.

I do agree, OEM is the way to go!
