    I don't know what happened?? The thread was there a couple of days ago. I didn't delete it. Is there any moderator on here that deleted it for some reason?

    Soooo .... I don't know what happened to the Group Buy thread but it's gone now. I'm sorry to the couple of members that were interested but I'm ready to buy now and not have to wait to gather a group of interested people. I'm not going to repost the group buy but I will forward the emails to someone if they want to pick it up and go with it.

    You'll just end up with a fuel smell inside the car. I started off with a filter and moved to a great big long hose to get those fumes to the back of the car.

    On the website for Saikou Michi catch tanks Saikou Michi Co. 2013 there seems to quite a few options ranging for $60 plus, which catch can is best. I was looking at the S1-OCC $85 + P&P, what do you think?

    Does anyone know what the ID of the hockey puck to TIP connection is? ARY with 70mm MAF.

    Will save me having to take it all off then fit it again to go buy something to plug it with :laugh:

    I used a 15mm can and 15mm hose up to the t-piece, works fine.

    I had bought an adapter but turned out the 15mm hose would stretch over the 19mm t-piece, so I just did that as it's neater and less connections to go wrong!

    i'll look into it then when I change my TIP, probably not a bad idea to do it all at the same time. Cheers guys

    I figured out what it was.. I cleaned the can with some solvent, I guess it didn't all come out so it was that which smelt! Never had a whiff off anything again! Vents to the atmosphere well so all good :)

    They have done but if you took it on track you would get crucified by the other track users... on the road its the motorcyclists that will suffer...

    I am sure you don't need me to explain why :)

    Anyone else not see the issue when venting to tip, i have been reading up on it and cant seem to find a definitive answer. Off boost the standard setup vents through the pcv valve and to the inlet mani, on boost through the hockey puck. But on the simplified setup it has no way of venting off boost if routed to the hockey puck, only when on boost. It needs to be vented to atmosphere. Unless it runs through the small bypass in the hockey puck??

    Quick question as I will be fitting mine soon. When you remove the pipe connecting to the brake booster and blank the pipe to the inlet mani. Could you not run a hose from the inlet mani to the brake booster therefore retaining pretty much the standard system or do I have it all backwards.

    I'm not 100% sure what you mean in your question Dave.

    Just stick to the guide as its tried and tested. The less hose the better in my opinion.

    I didn't like the stuff on the market. Also running mega boost you do get more than normal blow by so more pressure in the crank case, if you have more outlets in the crank case you have less pressure

    think he wants to keep the brake booster connected, you can either blank it off or use a single bit of hose, if you have an aum then its seperate to the pcv anyway so mines still connected tbh makes no diffrence (could be wrong please correct me)
