dr_jekyll Posted June 19, 2011 Share Posted June 19, 2011 i was searching the web for the best solutions on fitting turbos to v8 with little space and i found this little beauty. http://www.clublexus.com/forums/sc-400-300/541023-wtf-1uzfe-turbo-im-either-a-genius-or-an-idiot-3.html about half way down the page questions . would this really work? how would the turbo being so far away effect performance and surly the turbo would need it own little sump with a pump to send the oil back to the engine? but all that aside , that looks super cool . im thinking 1 uz with a t78 instead if a backbox Quote Link to comment Share on other sites More sharing options...
Homer Posted June 19, 2011 Share Posted June 19, 2011 Rear mount turbo's are used in the US, most often by the muscle car groups. I don't have any data but can't see them being very efficnet due to the weight and long lenghts of pipework needed Quote Link to comment Share on other sites More sharing options...
johnny g Posted June 19, 2011 Share Posted June 19, 2011 That's decent. Saw this on a Porker 911. Looks mean as hell. Quote Link to comment Share on other sites More sharing options...
Havard Posted June 19, 2011 Share Posted June 19, 2011 That looks insane Craig. You must do it..!! Quote Link to comment Share on other sites More sharing options...
Ricky49 Posted June 19, 2011 Share Posted June 19, 2011 Looks impressive Though rears on the porker look massive Quote Link to comment Share on other sites More sharing options...
RobD Posted June 19, 2011 Share Posted June 19, 2011 There's a Lexus IS-F in the states with twin turbo's tucked in behind the rear bumper, looks nicely done from what I saw of the video, the owner looked a complete tool though! Quote Link to comment Share on other sites More sharing options...

Swampy442 Posted June 19, 2011 Share Posted June 19, 2011 It cant be that efficient though, the gas will have cooled and contracted? Plus you have to pump the compressed air back up the front. Must work as people are doing it... Quote Link to comment Share on other sites More sharing options...
dr_jekyll Posted June 19, 2011 Author Share Posted June 19, 2011 it looks cool and would make things like changing turbos ect easyer and more acessable but i cant see it working too well . the porker is a different story as the engine is back ther anyway . but it is different hmm , v8 rear turbo . ot in the consideration pot. on the upside thers pleanty of time for the charged aiur to cool Quote Link to comment Share on other sites More sharing options...
dude Posted June 19, 2011 Share Posted June 19, 2011 On rear mounted turbos like that you do not need an intercooler so the distance is not so bad. Quote Link to comment Share on other sites More sharing options...
dr_jekyll Posted June 19, 2011 Author Share Posted June 19, 2011 interesting , so would you just use flow for the oil returne or will you get a backlog in the core and dop the seals ? and in the case of the exhast gases cooling and compressing would running a smaller hotside compensate for that? the mind is turning over now Quote Link to comment Share on other sites More sharing options...

dr_jekyll Posted June 19, 2011 Author Share Posted June 19, 2011 i think i will experiment with this . finish the season and get playing over the winter. Quote Link to comment Share on other sites More sharing options...
Tyson Posted June 20, 2011 Share Posted June 20, 2011 Would be a nightmare going over speed bumps if you catch one. You would probably need a guard plate to protect it from debris, bumps and kerbs. Quote Link to comment Share on other sites More sharing options...
EMPEROR Posted June 20, 2011 Share Posted June 20, 2011 I saw a couple of days ago Grand Cherokee Hennessey... the turbo was just below the passenger and the air filter was pointing straight down, sitting just few inches of the road... that's insane IMHO (especially on rainy days)...

Ricardod Posted June 20, 2011 Share Posted June 20, 2011 Ive seen those rear mounted turbo's allot lately in the US, especialy with corvettes and other V8 powered cars with less engine bay space. i cant see why annyone would do this other then not having the space in the engine bay, it would suck a very large amount of dirt into the air filter and can kill a turbo pretty quickly due to shaking of exhaust. Also the IC piping is miles long propably causing turbo lag. it has some positive things to it too, spool up on these back mounted tubbys should be better, its just that the air needs to deliver a pretty long distance to the intake mani.

dr_jekyll Posted June 20, 2011 Author Share Posted June 20, 2011 iv considerd that too an the air feed to the turbo will be going up into the car and breathing in place of the rear pass side window?(obiouslt with a moulded plastic window in place if you can picture it) . as for the shaking i was thing 2 study steel mounts to bolt to the chassis with rubber bushes.

dude Posted June 21, 2011 Share Posted June 21, 2011 Well it looks like we may be doing this on a customer car now and too make it more trick we are going to make like a little dry sump system in the boot to supply the turbo with oil, so it has its own little standalone oil system.

a98pmalcolm Posted June 21, 2011 Share Posted June 21, 2011 I seen this a fair bit on the newer Lexus's. They sound great as the turbo spool isnt blocked my a bonnet.. I have a book called street turbo charging explaining about this system type Quote Link to comment Share on other sites More sharing options...
