Have any of ya’ll ever run titanium connecting rods? _________________ Forced induction can overcome a lot of obsticles that gets in it's way

How much fkn money do you think guys on here have?
Jezzus if a set of valves is $4000 how much do you think a set of rods is worth? |

I made semi-custom titanium Ferrea intake valves. They were about 700.
Rods will set you back about 3 grand from Pauter, but the benefits will be few, unless you’ve exhausted all other options for weight reductions. _________________ "A petrol engine can start readily, run smoothly and give every appearance of being in good order, without necessarily being in good tune." - Colin Campbell, "The Sportscar Engine" |

sorry if titanium is out of your budget but there's no need to ruin or divert a post because of that. considering some of the rides ive seen on here and a few of the lurkers ive talked to that have well over 20k in some engines they've built , and ive seen several Pauter engines in the classifieds for sale for 30k + , I dont think my question is unreasonable to assume that people here can afford them. in fact I think it'd be insulting to assume the samba's members couldn't _________________ Forced induction can overcome a lot of obsticles that gets in it's way

I've ran aluminum rods. They're drag race only. |

JET used to make them. Berg sold them.
Pauter used to make some aluminum rods too, sand and drag stuff. I'd guess lifespan was short on those. _________________ it's advice. If you don't like it, ignore it. Don't argue.

the thing about aluminum rods is that you have to untorque them in between race weekends.... mainly because the cap serrations which are completely necessary will cause fractures if left torqued _________________ Schnell, SCHNELL!

I was just informed today by Carrillo that titanium rods have a lifespan of 120 hours. I figure thats just long enough for a race season _________________ Forced induction can overcome a lot of obsticles that gets in it's way

Porsche GT3 street engines (and similar street Ferrari's) run Titanium rods as stock and sold tens of thousands.
I know for a fact that GT3 engines can run 200K kilometers without rod issues.
Also older Corvette engines run Ti valves as stock. Those surely run very high milage on the valve train when maintained properly as well.
Special care/procedure and tools upon removal and re-assembling is needed though.
Ti as a material for valves and rods works (very) well imo. _________________ '75 SB 1303 2,4ltr T4 turbo: 10.58 @ 129.9mph

yeh the guy at Carrillo mentioned that but said the oem rods were beefier. so if the stock rods will last that long because their beefier are the Carrillo ones just weak & flimsy ? how does one titanium part last thousands of miles and the other a couple hundred, maybe. _________________ Forced induction can overcome a lot of obsticles that gets in it's way

There are a TON of things that play into that. Ultimately it is down to the design goals. What may seem “weak and flimsy” for a road car expected to go 150k may be plenty beefy for a race car that only has to run short distances for a limited time.
There are several Ti alloys commonly used, each with different strength and fatigue properties. The solution treatment, aging process, and any heat treat processes greatly affect the strength properties and size of the grains. The forging process changes alignment of the grains. The beams section profile and length changes the columnar buckling strength. The geometry and surface finish have a large impact on fatigue strength… so many other things.
It’s all about the design goals. A rod for a dedicated race engine and a rod for a high performance street car have different priorities. That’s all, really. _________________ 1800 Type 4 Berrien 295

The weight of the reciprocating mass and piston speeds play a large part in rod life. Run your titanium with a sub 300g piston (custom) and you can drive it for a very long time. _________________ "A petrol engine can start readily, run smoothly and give every appearance of being in good order, without necessarily being in good tune." - Colin Campbell, "The Sportscar Engine" |
