Gaz6002 Posted September 25, 2007 Author Share Posted September 25, 2007 Ah I see, fair enough It's only a T61 mate The design would cope with higher airflow though, i'm convinced of it Quote Link to comment Share on other sites More sharing options...

mikeyb10supra Posted September 25, 2007 Share Posted September 25, 2007 NOW, that's a proper air box, well designed and well made. Superb work If I could make one tiny criticism, you may want a longer section of soft hose, or ideally a section with a bellows in it, to accommodate engine movement. A set of TRD engine mounts will limit that. Exactly what I was thinking....well done that man Quote Link to comment Share on other sites More sharing options...

Ryan.G Posted September 25, 2007 Share Posted September 25, 2007 Just to add to this i made a custom airbox using standard box and filter to do some testing and never found it to be a problem with restictions. In fact i made 503bhp @ SRR with it in place when i was running lower boost. Here is a pic of what it was like Quote Link to comment Share on other sites More sharing options...
Muffleman Posted September 25, 2007 Share Posted September 25, 2007 Obviously the wrong forum, but I'm not really active on IMOC. Have you ever created anything to shield the air intake on a MK2 MR2 ? Quote Link to comment Share on other sites More sharing options...
JDModified Posted September 25, 2007 Share Posted September 25, 2007 Getting cold air into the mr2 intake is not really a problem due to the location of the rear entry air ducts, the only intake air system i fabricated for the mr2 was a very similar box, following the lines of the arc, i must say though i do like the stainles approach.

Tricky-Ricky Posted September 25, 2007 Share Posted September 25, 2007 Really nicely thought out mate:) one further suggestion, i would be inclined to cover it in some kind of heat wrap to keep the ambient engine bay heat from being absorbed by the aluminium, that should help induction temps further, don't forget that the temp under the bonnet can sit at 50C:( Quote Link to comment Share on other sites More sharing options...

Jake Posted September 25, 2007 Share Posted September 25, 2007 Gaz6002, Is your oil feed to the turbo usually at that weird angle? That can't be doing it any good. Quote Link to comment Share on other sites More sharing options...
Gaz6002 Posted September 25, 2007 Author Share Posted September 25, 2007 Gaz6002, Is your oil feed to the turbo usually at that weird angle? That can't be doing it any good. We had fitment issues with the whole PHR turbo setup as it sits at a funny angle on the manifold. As stated Jake, it's a work in progress and isn't even running on boost yet but yes, for now it sits at that angle and seems to work fine.

Chris Wilson Posted September 25, 2007 Share Posted September 25, 2007 Looks OK to me, so long as the drain is within about 15/20 degrees or so of vertical. Quote Link to comment Share on other sites More sharing options...
Homer Posted September 25, 2007 Share Posted September 25, 2007 Hi Jake could you elaborate?? From what I've heard from several tuners, it best to keep the oil feed and return as close to vertical as possible. As I'm sure you know after the little bit of turbo work you've done ( ) the oil feed and drain is gravity fed. If the oil drain is off vertical it can cause hot oil to pool and burn in the cartridge. This is 2nd hand info, but every trader I've heard from (except turbofit) recommend to keep it within 5 degrees of vertical. Edit - erm, and also CW in the post above Quote Link to comment Share on other sites More sharing options...
TLicense Posted September 25, 2007 Share Posted September 25, 2007 Gaz, That looks really well done! Nice job I should have taken a wander out to have a nose round yours and homers cars. Next time..... Quote Link to comment Share on other sites More sharing options...

Edit - erm, and also CW in the post above The oil FEED is most definitely NOT gravity fed, it's at full pump pressure. On ball bearing turbos FLOW may be limited by a restrictor, but pressure is still line pressure. the drain is by gravity though. Quote Link to comment Share on other sites More sharing options...
Jake Posted September 25, 2007 Share Posted September 25, 2007 If the supply is pressurized (which it is) then surely then return is too. Seeing as the turbo is a sealed unit I mean. Quote Link to comment Share on other sites More sharing options...
b_have Posted September 25, 2007 Share Posted September 25, 2007 3mm (restrictor) in 12mm out so no pressure. Quote Link to comment Share on other sites More sharing options...

Jake, that is not the case. Only feed is pressurised. It is not a sealed unit for oil circulation purposes, the return is connected to the crankcase which is nowhere near oil pump pressures! That's why the return needs to have a diameter several times larger than the feed, too. Quote Link to comment Share on other sites More sharing options...
JDModified Posted September 26, 2007 Share Posted September 26, 2007 Just catching up with this thread this morning, the way i see it with any amount of pressure over .5 bar going through the supply line will ensure perfect oil supply to the turbo. Once again thanks for all the comments and suggestions. James Quote Link to comment Share on other sites More sharing options...

Once again thanks for all the comments and suggestions. James It's not the oil supply thats the issue, it's the drain. It it's too far off verical the oil won't drain properly and will cook inside the cartridge. At least this is what I've always been told...
