Advantages of H-Beam rods over stock in a 2.0L Options

[lonewolfe]

What are the advantages of H-Beam rods over stock rods in a 2.0L motor? I know the H-Beams are lighter and stronger but in terms of performance what are the advantages of using the lighter rods?

This is primarily for a street car. Maybe some auto x but 95% for the street. I have a set of KS flat top 94's but may bump it up to 96's for a 2056. I'm thinking of using a Webcam 494 cam and around 9:0 to 1.0 compression. I'll be running a pair of Dellorto 40's & SSI heat exchangers.

That cam won't make power over 6000rpm, H-beams are a waste of money.

Hi Mark! Thank you for your replies. From all your posts I've seen on here I can see you have a lot of experience and knowledge about Type 4 engines. I would like to squeeze the most performance I can out of this car while maintaining reliability and good street drive ability. I'd also like to keep heat in the car and I have a virtually new set of SSI 2.0 heat exchangers. I also have a pair of completely refurbished Dellorto 40 carbs. I have a couple pairs of 2.0 heads in great shape. What cam choice would you suggest that may be better? I live in the SF Bay Area so I'm basically at sea level. Any input will be appreciated. I have most of the parts needed and am not interested in a Raby cam kit for this motor. The Raby kits seem to be the Go To solution for many on here but I wish to have an alternate solution. I'm sure his stuff must be awesome but I want something different. Elgin or EMW cams are another option.

Nothing? I think this thread is dead in its' tracks!

Sadly the discussion of modified Type IV's is going to be less and less it seems as those that are in the know move on to something else (IMG:style_emoticons/default/sad.gif)

Thanks for the reply Mueller! Sometimes it's like trying to find hens teeth to get information. Unless one is upgrading to a motor from a 911, Subie or some V8.

How's your new 914 coming along? I read on here that you finally found another one. I met you at a 914 breakfast get together a couple months ago out in Pleasant Hill. I think you were driving a Range Rover as I recall. I'm surprised Jake did not pipe in since his name was mentioned.

Yep agree, I've been building engines for over 25 years, I used to give lots advice, I got tired of being told I don't know shit from armchair engineers that read something on the internet.
I don't give much advice anymore.

I totally understand Mark! There are a few opinionated people on here! That's true in any forum. Most are very cool and helpful!

The worst ones are the guys who know enough to be dangerous. They have done a few things a bunch of times, and many things a few times, and know the theory, so they can sound really authoritative. But then you find out that their car hasn't run right in years... (IMG:style_emoticons/default/unsure.gif)

Uh wait, where was I going with that??



BTW, I recall reading that the gear-driven flat-fan setup in the 935 sucked up something on the order of 30 HP at redline. Not a big deal if it helped your 700 HP motor live through a 24 hour race, but kind of a big deal to those of us with 100-200 HP motors.
