RX4 BridgePort Turbo

I\'m not sure that manifold will handle the boost, you need to use brown tape for maximum strength!

[Will66]

Duct tape, it\'ll hold and be shiney like the chargecooler!

[Grant Monkhouse]

Iv got some special chrome foil tape I stole/borrowed from the guys that lag all the pipes at work. It\'s strong stuff

[Will66]

But will it take your MAAAD boost?

[Grant Monkhouse]

The boost will be fine, but I\'m having concerns about the water and methanol destroying the card:(

[Will66]

That\'s a worry, also if it\'s after your injectors then the petrol will really mess up the glue.  I\'d probably run a metal manifold, it\'ll be heavier, but avoid all these problems! :Laugh:burnout

[Grant Monkhouse]

The plenum is before the the TBs. good job iv got some 3mm ally in my garage to cut out tonight

[Will66]

Good good, I am all for elegant engineering solutions and stuff but I think an ally intake plenum is the way ahead.

[Grant Monkhouse]

Well I was thinking titanium but I can\'t quite cut that with my tin snips

[Grant Monkhouse]

Started off with this


Finished with these


Got to fold the 2 side pieces and then get it welded up, can\'t wait to have it finished

Coming on very well Grant.
 
That\'s how I usually end up with shapes, lots of cut out card shapes and finally finished aluminium or stainless pieces. I haven\'t any welding equip though, so you have the added advantage.
 
Good luck, its great to see guys designing their own stuff.

We can\'t weld aluminium at my dads, need a 3 phase supply for a decent alli welder. Got at least 3 people I can go to though to get it done. Think the one lad will be happy to do straight welds as there won\'t be any gaps from my crap cutting skills on 4" piping. Lol.

Will hopefully have the plenum all finished by next week and then the final little pieces on the charge cooler done, then it\'s onto the radiator. Prety easy job I rekon.

Just remembered iv got to make a sump too, anyone recommend what thickness Ali to make it out of??

[Will66]

I think Greddy\'s ally sump for the RX8 is 6 mm aluminium.  Although since you\'re probably getting 3 times the power out of yours then you may gain something from a thicker sump adding some stiffness to the block.

I was thinking of running a sandwich plate made from steel in between the sump and the block?? Similar to my gear box brace plate that iv made. I\'m only going for 500 HP, it\'s not really that much power, if we were talking 750+ then I would say I\'m goin for lots of power.

[Will66]

True, I was going on the assumption that an RX8, what the greddy sump is for, makes about 180-200bhp stock and you\'re going for over 500 bhp.  Steel Sandwich plate would help with block stiffness though.
