Has anyone had any first hand

Has anyone had any first hand experiences with the krank vent systems which have been mentioned in previous threads? Are they difficult to install and what are the benefits/ results?

Hi Bill,

I know what Crank


Hi Bill,

I know what Crank Vents are and why they are helpful in some applications. Not sure what you mean by Krank Vents, I presume you are reffering to the same Crankcase Venting Products that are on the market for other engines. If not please correct me. Also not sure why you think a 308 would need additional venting?

Regards, JRV

Hi, JRV--I was inquiring becau

Hi, JRV--I was inquiring because I just came across a site , <durable1.com> , which advertises a newly designed crank vent for 308's. It suggests a decrease in oil seepage and possible increase in HP, although the dyno #'s aren't in as yet.

>>It suggests a decrease in oil seepage and possible increase in HP,<<

Hi Bill,


I will agree that reducing crankcase pressure would reduce the possibilty of seal leakage where pressure is an actual contributing factor, and I have seen plugged up crankcase pressure systems blow seals and cause a huge oily mess....on street engines with rings in good condition I have to wonder how much "relieving" is neccesary beyond what the factory already took into account with the original design?

Again on the HP issue I agree in theory (and in practice on race engines) that reducing CP can or does allow a HP increase. How much depends on many factors, but I'd guess on a street engine maybe 1% at 6K-7K rpms.

So then the question becomes, it's certianly not hurting the engine, and may be marginally helping, so what is that worth in terms of $$ invested?

HTH's

Regards, JRV

As To the Dyno #'s, no , t

As To the Dyno #'s, no , they aren't available yet, We finally got the word that The cams for that motor will be sent from Frank Capo hopefully this Friday. (they were ordered, prepaid, in July). So hopefully it will be soon now, and I'll be ab;e to authoritavely post them. This debate has been going on for some time now, and I'm looking forward to the answers. I can only speak from experience, and that being good, or I would not offer them for sale. As to the question of how well they reuduce leakage, I put set on Larry Turner's GT4, as it was leaking badly from the front cam cover (bad enough to start a fire), and it slowed the leak to the point that it is driveable, so they do create a certain amount of vacuum. How this helps increase power, I would defef the question to the original patent holder, Dr Ted [email protected] E T Performance.com, who is the originator.

Kermit,

Welcome to Ferrari-


Kermit,

Welcome to Ferrari-Talk.

Maybe it's possible to run a test of crankcase pressure/s with & without this vent system so that some comparitive situation can be created?

If some data can be gathered, this crank vent system might be appealing to 12 cylinder guys also.

Regards, JRV

I plan on running a full batte

I plan on running a full battery of tests on the dyno, as soon as the cams get here, and i can get the 308 on the rollers. BTW: your welcome, my pleasure.
