Hello
I have a type 1 turbo engine that came with std Porsche 912 rods, it's going on a drag beetle, as I wouldn't like to rely on those rods to make power -and keeping in mind that I don't want to work heavily on the crank changing bearing sizes etc- is there any good alternative rod in the same dimensions that could hold like 300HP at no more that 7000rpms?

Carillo has 53mm journal H-rods... Great stuff.

Pauter Machine, www.Pauter.com  They should have them on the shelf
 

Thanks a lot

probably I'll give me a try with Pauter as more afordable

Not to hi-jack your thread, but what are the limits of 912 rods with quality bolts? Can they take say, 125rwhp... 6500rpm max??
They are substantially lighter than a VW rod, shorter, and a rebuilt set is reasonably priced... All good points in my book :)

I have raced mine for two seasons, 2276, 7500-8000rpm, 180-90ish hp. No trace of damage/wear when we took them out this winter.
Johannes´s 1603cc engine used LIGHTENED 311 rods...  :o

I think in good condition they can take alot more than you need,
its just the life cycle they have had is unknown,unless you can find some new or with definate low miles on you are playing the lottery with your engine

cheers richie

Hello

sorry that I wasn't very helpful with details, the rods were (not any more) on a T1 turbo for drag racing, we were on the dyno where it made 282HP at 6900 and after the dyno session I was told that they were 912 rods inside, I just felt so lucky that we didn't killed ourselves! The engine came ready to run to a friend of mine and afterwards he found those data of the engine, I think that you all agree that probably they weren't up to the task..

For a turbo engine i would go with Pauter or Carrillos . May be Pauter has some in stock .  BUT , we drove this 912 rods on the circuit track on 2,9 Type 4 engines up to 240 hp . This was in the early days when we could not find any others like the cunningham we use now .

Great days...those cars in W4 class!
I remember a VW Speed article of a 2,9 T4 engine by Holzapfel (for Herr Doktor Jozef Gerhold  ;D) who also used those. I always thought they were predominantly used because they were so slim on the bottom and with a 86 stroke in a type 4 casing you want all the clearence you can find.

You did prepare the lime green torsion beam car back then Udo?

Hello

thank you all so much for your input, probably as Udo sugested I'll keep them for another project cause they seem really good and I'll get some Pauters for this turbo engine, thanks again

that's a good solution . You can use the 912 rods for every street engine you want ...

@ Airspeed . Don't know what car you mean , i have two  2,9 and one  2,7 engines on the circuit track  :D One 2,9 still has the porsch rods inside  ???

I always thought you were responsible for the engine and/or heads in this car Udo:

dirk torwesten..
the engine was a 2000ccm typ 1
the last years of the "käfer-cup" : max 2000ccm and max 7000rpm if i remember right.

912 style rod have the bolt/stud as one piece with the cap,
so no simple way to upgrade the bolt.

That being said,
the 912 style rod is an excellent choice for most engines,
if properly sized,
and  crack tested...particularly where the stud meets the cap face,
and in the beam near the small end.

Type 4's can benefit from the added clearace avalable due to the design of the cap/stud beaing one piece.
This assumes you have a crank with the matching rod journal....

This nice car had a 2,9 (912 rod  :D ) engine from me in the early 90's 245 hp . After that they changed the rules and i did a 2,0 Type 1 engine 175 hp . Then the car was sold and got a 2 ltr engine (wbx case )185 hp . Type 1 as a spare engine .  Now it has a 2,4 (wbx case ) engine 225 hp .
