Titanium or Aluminum connecting Rods?
- Thread starter bigboy
- Start date
Lightweight would be my guess. Surprisingly the NHRA Pro Stock Suzuki’s use steel rods and the huge Buell V twin motors with a much longer stroke and bore run aluminum rods. Go figure.

Hi. Do not forget carbon fiber rods. Auminum rods havs a short life span they need to be replaced after a set number of tuns. On my motor I went with custom steel rods I called Carrillo1 told them a had a garrett G42-1200c turbo so I wanted rods for 13500 RPM with an over run to 14200 RPM. So $1400.00 later ( as I am a dealer ) for them came a custom set of rods pins and bolts. I am still looking into CF rods. Also Webb Cams ground a custom cam for me and JE Pistons did a custom piston. Every thing that needs to be coated was done at IA coatings in Huaton TX. The head was done at HMP with Inconel valves and the exhaust is also made of Inconel and eas also coated at IA Coatings too.
What’s your target date to fire it up?
I'm just riding street so what would titanium rods do for me?
I looked into titanium rods back in the mid 90's , they should be excellent choice , still super strong like steel , but lighter . I would think there would have to be some shortfalls compared to Corrillo Rods , but street you might get away with relatively stress free easy life .
Isn't the carpenter motor build comming equipped with aftermarket rods ?
Pro stock bikes here in OZ use a lot of old tech compared to some other bike types . They still use carbs ( Lectrons ) , and wheelie bars . I am not sure about engine rules but the US Suzuki running steel rods would have to be a compromise compared to what the twins can run to level the field . Some of the no bar bikes are quicker nowadays , which I find amazing .
This is pic of AU $16K billet cylinder head that a fella I know bought for his pro stock build .
Jewelry! Wow

Anything that reduces weight in a rotating assembly is a good idea ..
Steve Knecum, the guy who built Bill Warners record setting Hayabusa engine highly recommended them in the engine he did for me .. They're expensive, but probably a good investment ..
I'd give Steve a call and ask his advice .. Great guy, and one of the best engine builders around ..

I just realized that billet head I posted #8 is not my mates , I think that is Busa . His bike build is GS1150 based . This is pics of his cyl head etc .
Reminded again , CNC mills are capable of beautiful things....

@bigboy , build seems to be more about ultimate performance / weight loss , so , guessing that is why he asks . Some of the bits he is picking up are certainly beyond most owners level of streetbike modification needs .

Some interesting thoughts regarding titanium :
Honda uses titanium con rods in their NSX, Porsche in their GT 3 ..
When you reduce weight in the rotating assembly you reduce the energy required for the piston to change direction at the end of its stroke ..
On a 300 HP engine, the weight saving alone generated by the piston not needing to expend energy to carry the rod itself up and down at each cycle, makes a difference of 35 to 50 HP for the same cylinder capacity. More power, for the same size, and fuel savings – even if this would matter little for the professional motor racer

The package I ordered does not come with titanium rods. And about your fb question I got a carbon fiber fairing stay. I couldn't find that thing anywhere lol.
I'm not sure I haven't really heard what effect they will have on a bikes performance. I know they will make the bike rev quicker and less weight but nothing more specific
I cannot remember my question bro lol .
In my fb post you asked what part i found
