Similiar to on my car Rolls, whether you saw or not? In front of the windscreen you can see them bundled up. You drill and tap a hole in each runner, pretty well same distance away from port so temps are equally measured. Actually I guess only if the runners are thick enough, otherwise weld on a nut or machine up a bung and tap a thread in that and weld it over the hole, which is what I did with my extractors.

Exciting stuff Noel! No doubt you will ring dad as soon as you know. Im always getting the information second hand..... I thought we were friends

Cheers mate. Well wastegate outlet is all tacked up, ran out of time to weld it. Lol no pictures sorry. However I have spent the last 3 hrs at work this morning working on the charger intake flange to accept a 3" tube to hook up the turbo outlet. Starting to take shape, Its going to be tight getting the turbo outlet plumbed into the charger intake though .

Looking good! Love the dimple dies, I want some!

Its steps back down to 3" to match up with the existing system I made when it was just supercharged. I didnt really wanna fork out for more mufflers and redo the whole system in 4". This will have to do! Its not an ideal step down either, its a 60 degree step rather then the proper 15 degrees or whatever its supposed to be. The first expander is more like what it should be.

Lol yeh I should have purged it, but I was too lazy to machine up some bungs. I seem to like doing things the hard way lol. If I was doing this all at work then I would have as material and machines would be there. But its done now. Took forever to weld it.....stupid lobster backs. Hopefully have wastegate outlet finished tomorrow night.

Lobster backs ftw Mike! Chris, I was given that one, however im told you can get them from a company called Midway Metals. MIght be a good place to check if you are in need. Thanks mate. Hopefully Ill have it finished and fully welded tomorrow, ready to bolt up!

The dump pipe is nearly there! Lobster back central in this bitch.

Nice achievement so far! Going to be a weapon with mid 500hp Noel. You will be buzzing tires like crazy!

Time for some big power Noel! Keep us updated.

Its looks similiar to the one I have. Though there isnt much to go by in that picture. This car will be even more competitive with all this development!

toyota mr2 electric/hydraulic pump????

Awesome! I wouldnt say getting out of control, more like its going perfectly.

We have run a rear head scavenge since we first setup our dry sump. When the oil line comes off there is oil residue in it and our pumps have shown no sign of wear from a lack of lubrication. So some oil is going down it, how much I have no idea. We also haven't blocked off oil feeds or ran restrictors other then factory so we would have a lot more oil in our head then others with restrictors. Perhaps if we did run some it might be a different case.

Yeh i had a quick look at that. There are many ways to do this and most of them work, just some will work better. Plugging the internal drains and scavenging from some point in the head, keeping any oil return from the head external it has to be better then letting oil drain back down right onto the crank. You will need a lot of vacuum to pull the oil straight off the crank where internal draininig onto the crank wont matter. It seems they all dont think scavenging from the back of the head has any merit. I guess if it isnt the lowest point then that would be true, as the obvious ideal drain/scavenge point would be the lowest point you can pick up. Like I said a while ago, doing my suggestion is probably more so for the hardcore setup chasing every bit of horsepower and benefit a dry sump system can provide.

Lol even though it is a street car, he will no doubt give it squirts here and there, probably race people as well because lets face it, you get amped up on occassion and it happens. But you are right, the gt30 would be the best pick. It is a good responsive setup that nets good low-midrange power.

Yeh but you don't build high powered cars to race on the street...

We don't have a speedo in our car so I can't comment, but purely racing exp here, around 6500rpm it would die off, but for most tracks it was pretty good.

lol. ahhh it would appear I did... But to get back on point, the most responsive our race car ever was, was when it had a gt30 on it. Exact build spec was standard head and valves with tomei stage 1 cams retaining the vct, 6boost manifold with gt30 with .82 rear, 8.2:1CR and we were making 320rwkws. Then when we put a water methanol setup on it it bumped upto about 360rwkws and it was amazing! Pulled like a steam train but used to die off abit early up high.

Lol there should be enough room for everything I need, I think. It is going to be a little tight where the outlet of the turbo goes into the charger inlet though. I will cross that bridge when I get to it But its very safe to assume the engine bay will look full!

That would be a shame, why settle for a fraction of an upgrade for no doubt a butt load more money.

Yeh the manifold is not too shabby. If I had spent more time planning it out It could have been done a little better, but its going to have to do. If i was doing it again I would change the merge angle of the collector so its closer to ideal around the 10-15 degree marge rather then the 25-30 degree its at now. I was worried about it being too close to the bonnet, but it appears to be further away then expected. Live and learn. I can say when its all in and going there literally wont be room for anything, at all. Certainly has been a long time. But its getting there. Im hoping for the same thing!

About time for some kind of update. So the manifold got welded and ceramic coated and is ready to roll. I machined up some adaptors to suit the wastegate inlet and outlet ports the other day and I just finshed welding the inlet adaptor to the exhaust housing to take the big 60mm wastegate. I pre heated it to about 300-350c before I welded it and then left it in the oven at the same temperature for 1-2 hours before turning the oven off to let it cool down overnight, hopefully slow enough that the welds wont crack. It was looking good before I put it back in for post weld cool down. Next stage is to do this 4" dump pipe and then merge the wastegate outlet into it.

lol ah, come on mate, fairs fair, it has a turbo and a relatively big one at that and its only an rb25!

Im almost there with that feat!
