altezzaclub Posted December 29, 2014 Report Share Posted December 29, 2014 Looking at the piping running around a turbo'd engine bay, I wondered if you can mount them vertically. The one advantage a non-crossflow motor has is the exhaust and inlet right beside one another. Maybe redrill the oil return to sit at the bottom near the exhaust bearing so the oil doesn't pool on the seal, and I assume the whole oil gallery in the turbo is full of pressurised oil so the inlet bush doesn't starve.. Probably some single-choke downdraught carb would be neater. Just point the exhaust manifold down more until the turbo inlet lines up with the current inlet manifold and stack the carb and air cleaner on top. What am I missing??

TRD ke70 Posted December 29, 2014 Report Share Posted December 29, 2014 In my opinion, NO! :no2: My thinking would be exceesive side loads. Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted December 29, 2014 Author Report Share Posted December 29, 2014 Ah- good point. So the bushes or bearings need a thrust face. Are they all ball-bearings these days? Quote Link to comment Share on other sites More sharing options...
Aussie_KE70 Posted December 29, 2014 Report Share Posted December 29, 2014 (edited) No not all, most Trust turbos like the t518z are bush bearing and nearly all 4wd turbos are bush plus most light trucks and mobile plant and fixed engines are all bush bearing. I personally prefer bush bearing turbos for the couple of 100 rpm gain from ball bearing chra's its not really worth the added money outlay. But again just my personal preference. Unless you want to go down the route of ceramic ball bearing. Now that's an option not for the faint hearted, but cheap options can be found in the Apexi IHI RX6 turbos. These were the developed by IHI for Honda in the 80s and 90s when the F1 used 4 cylinder turboed engines. I'm not sure if you know that your limitation is getting a carbon compressor seal for a draw through system, this is to handle the benzi / petrol going through the compressor housing. I hope this helps Edited December 29, 2014 by Aussie_KE70 Quote Link to comment Share on other sites More sharing options...
corollaart Posted December 29, 2014 Report Share Posted December 29, 2014 wHAT ARE TURBOS is it some new thing ,like yo yos. Like face tube thing!!! BA! it will be gone by xmas Hi Keith :wave: Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted December 29, 2014 Author Report Share Posted December 29, 2014 LoL Rob... just thinking... Christmas time y'know.. the couple of 100 rpm gain from ball bearing Ah, so the bushes work fine still. They must have some sort of thrust face in there to stop end float on the axle. carbon compressor seal for a draw through system Something else to look at too...

LittleRedSpirit Posted December 29, 2014 Report Share Posted December 29, 2014 No way to cool the charge, and turbos get pretty hot. Maybe not the best right underneath the carby for packaging and safety reasons. Cool idea though. May as well build it and see. Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted December 29, 2014 Author Report Share Posted December 29, 2014 No way to cool the charge, and turbos get pretty hot. Yeah, I figured what you give up in boost you gain in instant response. Maybe the intercooler far outweighs the lag. packaging and safety reasons. hmm... wouldn't want carby leaks! It would be a killer when you turned the motor off, probably boil the carb dry. So, turbo sock, insulation plate, water-cooled compressor... Injected motor would be the answer!

Super Jamie Posted December 30, 2014 Report Share Posted December 30, 2014 The best setup I ever saw moved the battery to the boot, alternator to the other side of the engine, and mounted the turbo to the right of the engine. Close enough to keep response from exhaust gasses, far enough away from carb not to cause problems. Quote Link to comment Share on other sites More sharing options...
snot35 Posted December 30, 2014 Report Share Posted December 30, 2014 From memory for at least a year or two the WRC Subaru Imprezza's ran their turbo vertically or near vertically. However, finding out details about that is going to be difficult. With the quick search I did, I could only find some poor quality pictures.

indelible Posted December 30, 2014 Report Share Posted December 30, 2014 the turbo oiling system would be far from the way it was designed to work with gravity for the oil drain so you would need a oil pump to drain it properly like they do in some low mounted subaru boxer engines like in turbo brz/toyota 86's + oil feed now not dripping onto the shaft as well might be an issue too i think the gains would be outweighed by the negatives/extra effort personally Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted December 31, 2014 Author Report Share Posted December 31, 2014 I looked up Aerocharge, small turbos with self-contined oil systems. They run ball bearings, but not thrust -faced, and have their own oil reservoir that feeds onto the bearings. So, an injected motor with an Aerocharge turbo on its side, and maybe the bearings replaced by a thrust set. See how the shaft is set off away from the heat of the exhaust side, not in the middle like most turbos. The gains might be outweighed by.... the cost of $2200 !!

67Rolla-Ken Posted January 1, 2015 Report Share Posted January 1, 2015 What car are you looking at putting this in? Quote Link to comment Share on other sites More sharing options...
camerondownunder88 Posted January 1, 2015 Report Share Posted January 1, 2015 A turbo charger has oil fed under pressure this goes into the thrust bearing and brass bush and gets lubricated. This would work fine sitting vertical. Once oil pressure up thrust face isn’t touching anything it is floating on film of oil..... Problem lays in the drain. Turbos need gravity to drain the oil. The oil comes out at a huge rate and I know for a fact Garret GT40 turbo I’m pushing 72L/min of oil through the turbo. Its hot foamy and the scavenge pump needed to shift oil would be a nightmare sourcing hooking up etc. Problem is most Garret turbos run the thrust bearing behind the compressor wheel. The rear Turbine shaft usually has two piston rings that seal the turbine end that’s it. When not spinning with oil pressure this can weep some oil and when oil is hot ANY oil sitting in housing tipped up runs out through the seals and smokes/burns on turbine wheels causing early failure. So short answer NO can’t run a turbo charger like this. Have a look at the KE15 turbo on here the red one has a nice hidden turbo setup could get ideas from.
