yes yes and yes, just got all hard fella. u know this is getting track ready.

amazing si cant wait to see this and speak to u. wat events u up for this year.

chris

just put noss on it and to the moon we go

i think the problem is with the outer edges of the hybrids inlet impellor touch the shell casing wen new not good as this is wer spool afficen coms from in new turbos. wen we removed 1 which had only bin on a couple of mounth the shell and inlet impeller showed signes of touching and this is not good at all. gutted.

chris

did you manage to sort your hybrid out ollie som 1 tells me it boosting good now mate.

ita going to be weekend after next fella head almost ready. this should impress on the rr day. i have a fuel reg to go on also. wats the travel lodge caleed again ryan.

he is a legend, he drove nearly a full race in 6th gear and won WTF!!!. u got to remember how many awsome drivers thr wer on the same track at the same time. and in 1500hp 1.5 turbos. with a H partern box WTF!!!!. and he made thm all look slow. i grew up on his driving and cryed wen i heard the news. he made F1 amazing to watch (risking all). and pissed all the other drivers off witch made for amzing racing. the FIA needs to understand that motor raceing is dangerus. and drivers like senna are 1 day going to com unstuk (we all make mistakes). the turbos are coming back in 2013 i have read. can not wait.

i get that a falling feeling wen i think about that race at imolla. the greatest motor sport died that day and only just now getting up on its feet.

1 of my fav races was wen he won in brazil, he drove out of his skin.

hello mate, yep the 5efhe 1.5 has higher comp pistons (11+) and is a frged part i have read, but i do need to measure the skirt to make sure it will fit the shorter stroke cylinder. the trd head gasket is thiner thn standard + stronger. the 5efhe cams have more duration and lift.

as far as the galnza s goes the dizzy is N/A (internal coil) but i have seen 1 running knock control and all the N/A i have seen do not run nock control. the s also has bigger injectors but thy have a bigger spacers on the mounts as the injectors sit higher on the manifold.

i have seen som of the newer starlets with a dizzless system, this system is probly the best (digital). and ryan on the money with the manifold thy awsome.

chris.

wen u talk about cleaner air you are correct in the way that u do not want these gasses to enter the engine on hard acceleration or wen engine is louding under full throttle condistion this is wer the per turbo pipe comes into play also. but i think im just about to talk gobaldy gook to alot of u all now so yes u are right about the cleaner air oil vapour free (helping maintain fuel octane).

chris

now how many of u have i just lost. i can even talk about the need to run your oil level nearer the low level mark, makes for nice fuel economy cruising benafits. but thr are ways to do this properly so do not just try it u will need a windage try thats y i was after 1 for this engine recent.

It wasn't my car I was talking about-I still have the pcv hooked up as standard and just a filter on the breather.

With what your saying I will just put the catch can off the breather then- for now, I may still get a second catch can to collect contaminants after the pcv.

I thought the whole point in catch cans was to keep the inlet charge clean, not because of fowling as you say.

Interesting!Thanks.

i can go on and on about emmision and the need for vac in the crank case as the positive presure on 1 side of the ?? and a negative presure on the other side helps the ?? to seal

chris

and street engines routinely show 3-4% hp rise at 10-12in vacumm but thr are a difference if run on a dry sump engine.

now are we ready for a complete head fuck. if you want to do the best job run a smog pump, back in the 70's & 80's thy used these systems to help reduce emmision. how ever i have draw up a breather system instead of pumping fresh air into the exhaust system in pumped the blow-by gases out of an oil/air separator (catch can) tank which has been connected to the crankcase and cam cover, these pumps (secondary air injection, vaxhall) are quite reliable and older versions are belt driven but these are not to be pushed rpm wise. and are protected from exhaust back-fires by a check valve. look up Moroso pumps these would be ideal but are large. the 4 vane 22641 pump will pull over 15in vacuum and the smaller 3 vane 22640 pump @ 12in the 3 vane is a bit better street pump i recon. now i have given this away wat am i aiming for com on have a guess. how will this benafit this engine.

chris

chris can you not just put up a diagram or pics of the proper fitting of a catch can? the original reason i fitted a catch can was because the breather i put on the rocker cover started spitting oil residue all over my fresh rocker cover.

are you saying keep the pvc valve connected standard and just have 1 line in? or could i not keep the pvc valve connected like standard but drill and weld a second nipple into the rocker so i will have 2 lines into the catch can with a breather on the catch can?

might be completely wrong but hey ho

cheers Dean

yep mate use a air filter relocation kit and use a pipe coming out the pre turbo pipe (air filter relocation pipe) into a sealed catch can then into the large breather pipe that is on the top of the rocker cover. simple this way u stop the main fouling issue of the TB, but a very good point has been raised here that i did not think about and that is chatter, best to run a dump valve with this system so as to not provide any back presure.

chris

If oil vapour/contaminants come out of the breather would they not also come out the pcv port?

EDIT-Since you edited your post.

Ok so your saying the best place to have a single catch tank is between the main rocker cover breather and inlet pre turbo?

My question above still stands-why does more oil vapour /contaminants come out of the breather port? I've seen catch cans inbetween the inlet and pcv with plenty oil collected?

how long u running for before u check the can fella. fouling is the main reason to run a catch can and thr is nothing fouling from the pcv after the TB. the other main reason is heat soak and finaly the breather to recert engine gasses. i have even seen a paint that ford use to stop iceing of the TB, as thy do not run a TB heater on the early Zetec engines this paint also help the air flow by reducing the frictional losses however tiny between the air flow and the port walls. but u could not clean out the TB as u would rub off the paint. slight oiling in the inlet runners has this same affect but the gains are very small. and was shown to me as a example of just how far u can go.

wat is your reasoning for having 1 on the pcv, wat problem u solving, here we go again.

chris

the main problem with this system is the large breather runs most of the time (wen ever u off closed throttle position) and it is this breather that fouls the throttle body and causes stalling and flat spots on set off and irratic idle even with a large intercooler to pass thw. i have seen it to many times, as it is this breather that get rid of crank case gasses on full chat. so putting a catch can in this line makes sence but wat problem u fixing on the pcv fella please do tell.

the main problem with after TB fouling is that oil gets on the inlet valve back face and because of the heat created in the combustion process heats the valve head up and cooks the oil (now carbon) on to the back of the valve this then build up and starts to restric the valve on low lift. now with this engine being of batch firing efi the valve head is cleaned along with the head inlet ports and the oil/carbon acts like a retardant (EGR) kind of. hence no problem with the pcv. hence y i leave it alone. if u running a sequential firing efi thn u would have to look at this agian and might have to work out valve time open and cross ref to injector duty, i would think u could just overlap the two in order to cool the inlet valve head and also add alittle vapour to the next round of inlet charge + cleaning the valve head. this is 1 of the reasons y the new fsi direct injection engines have complex breather systems in order to not foul the inlet valve

give me 5 min and i will type a full explanation on the 4efe and te breather system and the pros and cons and wer and y u put the can in and wer to put it.

chris.

stay away from the fags. lol i just thot that something like this thats so simple for you and causes so much debate everywhere else could have used a proper answer and after reading your reply i now think catch cans are the devil thats the one thing i think this site lacks is alot of tech threads just explaining frequently asked questions. the knowledge you have on engines is awesome tho. the tech section should be yours

maybe if you put a catch can between your mouth and your fag it will help keep your breathing system healthy ?

Russell

thr are alot of my ideas that at the moment are just thery like using the flat top pistons for the N/A i need to find out the valve to piston clearance if im to skim lots off the head. might need to have som pistons made up.

lol yep give it to me boys i do deserv it. am just used to going on the tech sites and if u even ask about a catch can you in for a ride donkey kong style.

chris

p.s just burnt som toast. and hung around in the kitchen for 5 so am good now. feeuuw.

sorry once again think this site and all u guys are awsome

chris.

do need a fag thw.

I can understand about there being nothing to pull the gases out of the catch tank but would it not flow anyway due to the greater air mass pressure creating the pressure to blow it out naturally almost in the same principle as reverse scoops the difference in air mass pressure is what creates the vacuum to let the heat dissipate? Also the inlet manifold pipe has been blocked off rather than contaminating the inlet charge in anyway and not leaving the hole there.

this argument falls flat on its face wen u bring block swet into the equation.

chris

no offence ment fella.

sorry if i com across like that lads just very simple thing for me, plus i have recent quit smoking so AARRRRRHH to everything that looks at me!!!. this is so simple so so so simple, its more frustration thn anything i think i have seen 1 starbo rocker cover with the correct fitted can in all the meets and shows i have bin to. and very sorry if i have made any 1 feel shit just very frustrated by this. as people turn booste up but cant fit a simple breather can think that shiz is backwards.

as for y i would fit a can to this engine well the TB would be my first port of call thy get very mucked up with oil from the inlet breather, this is the main cause of peoples idleing problems a simple clean will yeild big results try it for your self i think u will find it awsome. so the can needs to go in the line that connect to the intake track and this is found before the turbo on the efi pipe thw the recert valve (never ever after the turbo). like i said sorry if i have upset any 1 but som times i feel the need to get u lads to think about wat and y u are doing these things. i could just give u the answers but u will not understand y or wat exact u are doing.

sorry once again if im getting a bit cocky thats not me just want u lads to stop and ask y u are doing these things. this engine breaths very well on its own and very good with just the pcv valve in and a filter head placed on the recert valve port (big port in the top of the rocker cover) which leads me to belive the cans are just under bonnet bling.

this is y u get suposing tunners on here walking round japfest talking ball bags telling people that these cars are unreliable and brake down, wen thy thm selfs do not understand wat thy doing with things so simple but completely nessersery. i would not give thm a butty to tuneer, rant over. (i need a holiday)

consider my neck wound back in

chris xxxxxxx

lov it british FTW.

i cant belive such a simple thing can cause such a masive head fuck, makes me question u guys. can some 1 tell me wat thr aim of fitting a catch can is. and wat problems with this exact engine thy are trying to solve.

chris

i made a lad on here sell his race tech rocker cover as he was blowing engine seals for fun but was running 1 bar of booste. and the engine was worn (leak off test carried out) my point is if u remove the pcv or the inlet track breater u are going backwards from standard engine breathing, and as far as venting to atmosphere goes thr are ways but i think u will just cause your self problems. and not to be done if u ask me. these race tech rocker covers make me want to shake som 1 and that person is the makers (really crap). thr i said it.

Not strictly true, the pcv valve only opens under vacum... so if u have a catch can that connects to the breather + the pcv valve and is then vented to atmosphere then there is no vacum to open the pcv valve. so it stays closed all the time. Thats why u gut it

sorry mate but wat alot a tosh, do not vent the catch can to atmosphere leave the pcv valve alone, can u know please explain how the full breather system works espeshaly on full chat (no vac), im not saying put the can any wer near the pcv leave that pipe alone. trust me i can explain how it works in great depth.

chris

no offence ment fella but if u use the pcv pipe and if u gut the valve u will be doing the inlet track (manifold plenum chamber a injustice) you will create a extra chamber like the brake servo and unbalance the system (turbulant air) thats the reason y the pcv valve is so restrictive. please people y u think these things are thr read enzo e123456 build thread me and him was just talking about catch can plumbing. y make somthing so simple into a masive shit. and if u say to get rid of the engine vapor totaly from the inlet track i would say y it aks like a egr valve, but it is the heat soak that can be improved upon.

just did a sex wee??.

lok at the fc 2000 analog with a c4 coil will be much easyer to fit and is cap discharge and also multi spark duration (MSD) the 3000 is digital and is worth that did more the msd 6a is analog but thr coil packs are duck all on the c4 (wen running this coil open up your spark gap and make sure your ingnition timing is bang on it realy does kick anus. (had a head gasket go on a track nova once and the ignition system was that good that the water squirting into the cylinder caused a super charging effect and it never missed a beat, u could watch the exspantion tank empty and expand like a baloon on aceleration lov um)

jacobs electronics mate is wer i shop.

chris

lol, lov u guys its easy, just put a catch can in the line that would normaly go to the recert valve on the standard engine big port (none vented to atmosphere), and if 1 of u guys says that u have taken the efi pipe off, i will tell u to look further than your noise and ask u to think wat pipe u replaced the efi pipe with and wer the efi pipe plumbs up to and wat its porpose is. sparky has a good example of a catch can using negative air presure from under the car, proper race style. lets see som brain action boys.

giggz is it wrong if im thinking about tossing 1 off to your avator, think im in lov i cant stop watching it

STOP NO NEED TO GUT ANYTHING, lets not make a meal of somthing so simple and that that important on this engine. and yes catch cans plumbed in wrong will blow engine seals and will get even worse if u running big boost.
