Just ordered my engine from wsrd.. There aluminum rod package come with

• R&R Aluminum Connecting Rods
• WSRD Spec Diamond Pistons

My purpose was to build a DD mostly in traffic ect with occasional street weekend street racing

Aiming for 800 to 900 hp on E85

Not sure if I did there rite thing ordering the aluminum rods as I read tJust ordered my engine from wsrd.. There aluminum rod package come with

Not sure if I did there rite thing ordering the aluminum rods as I read they don't have long life like say the turbo tuff rods ect

Is that true? They don't have long life like say the turbo tuff rods ect

 

Maybe this link can give you more info.

 

Aluminum has a short service life and isn't meant for DD.

 

interesting video from Real Street. It sounds like it is possible to use aluminum rods in DD as long as it was built to accommodate the right clearances. I thought the aluminum just gets weaker of time because of the beating it takes. I wonder what's the longest lasting aluminum rod DD is on the road today...

 

800-900hp, Evo, and daily driver do not belong in the same sentence.

That being said, keep oil temps below 230*, while also not beating on it until the oil is above 130*, and you'll be fine. SO you def need an oil temp gauge. The sensor belongs in the oil pan, so get a bung welded into your pan before you put it on the engine. And run the oil WSRD recommends.

 

Here's so good info on aluminum rods. paragraph 7 is where they start talking about aluminum.

BME has no problems with their aluminum rods being used in a street engine due to their proprietary alloy. R&R also has claims of proprietary alloy. The old school train of thought that aluminum can't be used for rods in a street car is just that, old school. Modern alloys are much different than they were in the 70's and 80's.

 

 

This is very interesting. I was always of the mindset to stay away from alum for street applications. Might be worth looking into on a future build.

 

Aluminum rods are awesome, dont be afraid to use them.
The rotating assembly WILL be very responsive on and off throttle.
Bearing life will be increased, but your talking 800 - 900 wheel, expect to stretch the rods sooner than later.
Dont forget to let the engine warm all the way up, this is very important.
If you were talking 450 - 550 wheel, then you probably can get years out of your build instead of just a handful of passes.
Dont be afraid to experiment..

 

i agree .

anyone selling 156mm aluminium rods ? I am looking for them.

 

BME or GRP may have them on the shelf but they had been built as needed. Worth checking into though, I looked and we dont have any on the shelf.

 

I have aluminum R&R rods in my engine that i built back in 2013 or so. They were part of an English Racing 2.2 SLR kit i bought before they started offering them online. I've put a little over 5,000 miles on it since than. Car currently is in my garage and fires right up and runs great! About to attempt CA smog actually. I always let the oil warm up before driving it hard and I figure i'll get 20k miles out of the motor before needing a rebuild.
