Ok here is a question for the BIG horsepower guys. Building a 700whp B20/Vtec Turbo. Already going to use Arias pistons. Getting a real good deal with the Crower Billets Rods. Can these Crower Billets hold up the 700whp. I know EAGLES may break so those are out of the question.

Manley and Pauter are of the same material right??? Getting the Crower Billet at an awesome price so need your advices about these 3 different rods.

thx....

 

Well, Chuck from alternative had some problems with bent crower rods last year and Crower told him they are only rated up to 600hp. While i've seen way more than that on them, I wouldn't use a rod that the manufacturer says isn't good enough! I've used pauter rods ALOT in motors making a ton of power, never seen a failure. Pauter gets my vote! Another thing to look at if you're making big power, make sure you get good wristpins. If you're using Arias pistons, call Tom and tell him to hook you up with the upgraded pins if you haven't already.

 

To be honest you can use either the Crower or the Manley, as long as you have a good tune up and avoid detination either company will be fine. I have used both with great success, it's all about the tune up, so if you got a great deal on the Crower go for it.

 

Gotta remember, as much as we like to think it never happens, detonation happens sometimes and you want parts that can handle it!

 

These are some excellent pieces. Money well spent.

 

Hey tony we posted at the same time, wierd. I haven't used the Pauters before, right now I'm rocking the Manleys they are working good but I never bent a Crower. Oh I agree with tony get the better wrist pin from tom.

 

 

tony, ive seen another user on here with some real thick "tool steel" wrist pins. are there any side effects to such a wrist pin ? weight?

 

Carillo

 

Tool steel is what you want. The best solution i've found is to take one of those real think tool steel pins and taper the ends down. The loads are greatest in the center, so the ends can be thinner. The downside is weight, but you're that's just going to put more stress on the rods. If you have good rods then you're fine. The pin will break before a good rod will, and with the big pins and good rods, i'd say the piston will be the first to go. The weight issue is more rpm related than anything though. Most people are doing fine with rpm related failures, even to 11k rpms.

 

thanks tony, will beefing up the wristpins have any bad effects on engine bearings? smashing them or anything?

on another note, what about some ALUMINUM rods ????? anyone?

 

From what i know about them, they're strong, light, and cheap. On the downside, need to be checked every so often, and have alot more windage losses. Don't know significant the windage losses are though.

steve over at omnipower is working on his titanium rods - from what i know they are in a couple of test engines already, ultra lightweight and supposedly able to last quite a long time as well without the need to check them all the time like aluminum rods

retail on them will be reasonable at only $990/set or so

 

james, have you had any personal experiance with a titanium rod? harsh on bearings ?


i believe titanium for rods is a bad idea. other than the fact that titanium is a lightwieght/stiff material, i dont see how it could "absorb" any "impact" like a chromoly rod or an alumium rod. i dunno. it seems like a titanium rod would do your bearings/crank/mains nasty.

also from what i understand about titanium, it will snap before it bends ?


(personal opinion, with no 1st handexperiance)

 

just did a little search on titanium rods, looks like you save about 33% of the weight.. i hope omnipowers are as cheap as stated above, because the ones i saw were about $800 a rod

 

Crower offers their rods in Ti, I think around $400/rod or so. We're running custom Pauter Ti rods in the NORAD 3rz motors.

omni ti rods..^^

 

Im currently looking for high quality custom titanium rods for my allmotor build. If anyone can point me in the right direction it would be apreciated.

Thanks,
Shant.

 

pauter rods are the ****

 

so tony is te titanium the way to go for a sstreet track car is theree any probs withthe bearings on them and do you have to check or the pauters or manlys the way to go for my application
ps working on another block thats why i ask

 

I believe for allmotor ti is would be very beneficial. Imagine ti rods on a K series. That would be nice.

 

Due to their price, for the most part, I think Ti rods are pretty much only worth it for all out race apps. If you're not turning very high rpms then you won't see much benefit. The omnipower rods sound like a good deal, maybe they'll be the next thing for big hp street cars?

 

i will stick withthe manley or pauters for my next set up for sure

Get em from Earl And,yes, that was a plug for Earl.

 

Doesn't Nascar use ti rods for their qualifying motors?
