If we're assuming this is how the OP drives then a) Its safe to say performance of vented vs seal catch cans are the least of his worries and b) When he gets pulled over and is asked to pop the bonnet it would be a better idea to have a legal setup over an illegal setup don't you think?
Once again, we're not builting top fueler buddy. We're talking about cars of weekend hobbist and for those applications seal catch cans are very good.
I think it's funny when people buy something and automatically thing it's the "ducks guts" too.
Thus why I installed my catch can after spending considerable time researching the concept of the product itself and then the various available brands.
Then, I didn't talk the product up until I had personally seen results using the product.
General concensus from weekend hobbists, weekend drag racers, performance shops, etc from around the world is that sealed catch cans do a fantastic job. Apparently you know better but have yet to actualy provide any evidence to show all of the above people, including my self, are wrong.
Finally, Pavtek, once again... have you looked at their site? They don't exactly build engines. They are professional engine builders and their engine are high performance.
Their engines vs the engine in the average "cheque book racers" car are chalk and cheese.
Yout posts are completely irrelevant. You may aswell start telling the OP that they should be running pure alcohol because Pavtek makes engines that run it.
I don't need to go past my "cheque book racer" stage because I'm quite happy with my engines performance. Does what I need it to so I'm not going to spend time and effort running bits recommended for a built engine on mine since there is not point.
Though I would be interested to know what you are running that is so much above and beyond the rest of us meer mortals quivering at the sight of you on your high horse?
I love you guys.. didnt expct soo much responce over a crappy valve bahaha.. and all on the thought that its rego... it is; but couldnt giv a f.. only doing this cos its cheeper for a filter on the rocker than replace the valve.. and yes i do rev the shi out of it. handles it well tho. not bad for what ive driven, mods are 36lb injectors, adjustable fule reg, 411 diff, and now the filter, and im removeing that exaust reburner thing.. basicly weld the hole for it and remove the plug on the whats it, make it look like its still in operation(i think ill cop it worse getting caught with that off than crank vent)... cos honistly i dont care anymore, cos of the kangaroo court hoon laws, basicly if they say it was you, game over...
only really asked in first place, cos things are made a way for a reason, didnt know why it was there, now i do and thx, now i can make a decision on set up.
would like some input on running the catch can to exaust.. i get the feeling that in high horse turbs they do that for like an after burner to spool up the turbo for about a 60hp gain, in saying that there must be a way to use the exauset as a vaccume to pull the air, burn crank gasses and keep the epa happy. but how to is a diffrent story, because too much vac will cause problems and if done wrong youll get exaust pressure up to the can blablabla rear main seal
oh and also, reshapeing the intake of the plenuim for better flow, works better then a plenim spacer, not takeing it too far cos of the air flow meter.. can only pull so much past that, (plemim spacer only increrases volume so when you do crack the throttle you get a burst of air rather than a controlled flow.. dont gain any top end at all; Basically creates pipe hammer, increased volume under vacc, open throttle air wants to normalise, rushes in fills volume then air behind still wants to follow momentarlly increasing pressure.)
