Frosty Posted October 10, 2016 Share Posted October 10, 2016 No. You only need the out and bypass holes. Quote Link to comment Share on other sites More sharing options...

d.p.n.s Posted October 11, 2016 Author Share Posted October 11, 2016 What about the hole that goes to the vacume lines?? ....need that Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted October 11, 2016 Share Posted October 11, 2016 What thickness plate you gonna use Dan? Quote Link to comment Share on other sites More sharing options...
d.p.n.s Posted October 12, 2016 Author Share Posted October 12, 2016 Well controversially I've gone steel over alloy... Reasons being its cheaper plenty of it at Work and it's something I can work with my self.. Also picked up 2 steel flanges for next to nothing from one of our GC members..and let face it if weight was going to be an issue ....I wouldn't have put a fucking huge SC there. But to answer you question Bart 8mm for now while I work shit out. Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted October 12, 2016 Share Posted October 12, 2016 Can you get any more? I'm looking for a bit of 8mm for my m62 too. Quote Link to comment Share on other sites More sharing options...
d.p.n.s Posted October 13, 2016 Author Share Posted October 13, 2016 Can you get any more? I'm looking for a bit of 8mm for my m62 too. not 8mm but might be able to get 6mm and i think i have 10-11mm at home Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted October 13, 2016 Share Posted October 13, 2016 I probably already asked. 8mm is the best balance between strength and lightness. Quote Link to comment Share on other sites More sharing options...

Frosty Posted October 20, 2016 Share Posted October 20, 2016 What about the hole that goes to the vacume lines?? ....need that Only if you plan to use it. I imagine that would be dictated by your manifold and how easy it would be to get lines too and or if you want to keep them hidden. 10mm is just thick enough but 12mm would be my choice. Remember it will need to be resurfaced after welding which can lose a couple of mm's depending on how good your welder is. Played with a M90 on a 1GGZE and used pretty much every hole, mainly because it made adapting the Toyota bits easy and in most cases the same functions where needed. In my case it was way simpler to make the plumbing from scratch and use a N/A manifold, also allowed an intercooler to be added. I ran up to 16psi with one still using the stock ecu with bigger injectors and pump. Without the intercooler I was lucky to use 10psi. You will need a good fuel system, superchargers use more fuel than the same power with a turbo. 1 Quote Link to comment Share on other sites More sharing options...

Frosty Posted October 21, 2016 Share Posted October 21, 2016 So you're using the supergharger as the secondary boost cycle? I think you may be underestimating how much you'll need to cool the charged air down, my feeling is you will need to look at something more than a single cooler under the supercharger. I've seen a Subaru STI intercooler modified with the fined section enclosed and used as a water to air style one with a small pump and AC radiator to cool that down. This system allows the intercooler to go almost anywhere, water to air is heaver but it's more efficient than air to air. Please don't take this as anything more than a suggestion but I would place the supercharger under the inlet on it's side with the outlet side facing away from the engine, this will allow the cold air intake for the supercharger to face upward at the back of the engine bay making it easy to get air into, pipe boosted air under the front pulley into the turbo in it's normal position through a normal front mount intercooler then use a normal front facing inlet manifold. This system will allow you to run a fixed boost through the supercharger and a conventional turbo type waste gate to control boost making the whole thing way easier to control and I think a tidier looking engine bay. Remember the M90 can supply a 5.4lt V8 at 12 psi all day but as the secondary it will be working very hard and I doubt you will be able to keep it's oil cool enough to make the system reliable, hot air in, hotter air out is a lot of heat soak to control. Over heating the oil is one of the known weaknesses in the M90. Quote Link to comment Share on other sites More sharing options...
