Guigsy Posted March 15, 2009 Share Posted March 15, 2009 http://www.boostlogic.com/xcart/product.php?productid=160&cat=9&page=1 This new revolutionary turbo kit will finally meet the goals of every turbocharger enthusiast. While compound turbocharging is usually used on diesel applications, we have devised a method for this kit to work on a gasoline powered engine. Unparalleled low and midrange torque coupled with high horsepower. There’s no need for nitrous as this kit spools up as if it’s always on nitrous. The compound turbocharger kit builds 20psi at 2800 rpms while flowing enough air to make 800+ RWHP! I dont know much about Single turbo's but that sounds interesting. anyone know of any running?

Kranz Posted March 15, 2009 Share Posted March 15, 2009 Hmmm, single????? With a low pressure and a high pressure turbo I'd say it was a twin I'd want to know about durability issues as the high pressure turbo will be under a lot of pressure..... if you excuse the pun Quote Link to comment Share on other sites More sharing options...

SimonB Posted March 15, 2009 Share Posted March 15, 2009 It doesn't say it makes 800bhp, it just says it "flows enough air to make 800". So in other they've done a bunch of guestimates with the turbo compressor map flow... Quote Link to comment Share on other sites More sharing options...

Wez Posted March 15, 2009 Share Posted March 15, 2009 (edited) the picture is just of one big turbo though Isnt there another turbo under the air filter http://www.boostlogic.com/pics/supratt/compound/BLcompound8.jpg Edited March 15, 2009 by Wez (see edit history) Quote Link to comment Share on other sites More sharing options...
Guigsy Posted March 15, 2009 Author Share Posted March 15, 2009 i dunno. the filter is in the way Quote Link to comment Share on other sites More sharing options...

Guigsy Posted March 16, 2009 Author Share Posted March 16, 2009 ahhh very interesting. looks like air is going out where it usualy goes in. stuff like that gets me confused. im still struggleing with the tt setup Quote Link to comment Share on other sites More sharing options...
Wez Posted March 16, 2009 Share Posted March 16, 2009 I wonder if they fitted a turbo speed sensor to the lower smaller unit Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted March 16, 2009 Share Posted March 16, 2009 That exhaust side looks massive in comparison to the compressor on the main turbo. That smaller turbo basically sucks the air through the bigger one by the looks of it. I can't see a by-pass for the smaller one when it all gets a bit fast either.

pedrosixfour Posted March 16, 2009 Share Posted March 16, 2009 Is compound charging not usually a supercharger feeding a turbo? Quote Link to comment Share on other sites More sharing options...
Ark Posted March 16, 2009 Share Posted March 16, 2009 http://www.boostlogic.com/pics/supratt/compound/blcompoundstand1.jpg Surely if you drive the second turbo out the back of the first turbo, you'll lose loads of heat, and therefore gas volume to drive the second blower. Also as previously suggested, pushing boosted air into the inlet of the smaller turbo would surely over-speed the compressor wheel. Cue many replacement turbos...Nice idea, but I just don't see it working. Quote Link to comment Share on other sites More sharing options...
SteveR Posted March 16, 2009 Share Posted March 16, 2009 I don't get it either. My understanding is limited but surely it can't be a good idea for reliability? Quote Link to comment Share on other sites More sharing options...

RobSheffield Posted March 16, 2009 Share Posted March 16, 2009 (edited) It would appear it will work well, if unlikely to last terribly long. Although...Surely that exhaust manifold needs lots of actuators.... Its kinda like a big high power blingy tig welded OEM TT setup Edited March 16, 2009 by RobSheffield (see edit history) Quote Link to comment Share on other sites More sharing options...

JustGav Posted March 16, 2009 Share Posted March 16, 2009 (edited) Hmmm, looks interesting enough.. Surely the smaller 2nd turbo is going to be a restriction or as others have said, it is going to spin like a like a really fast spinning thing. I would have assumed it also has a slightly smaller exhaust manifold header which would create a very interesting flow pattern in the manifold never mind heat spots, but doesn't seem to be the case. Anybody notice that they have been doing initial trails on an NA http://www.boostlogic.com/pics/supratt/compound/blcompoundstand1.jpg http://www.boostlogic.com/pics/supratt/compound/blcompoundstand2.jpg Edited March 16, 2009 by JustGav (see edit history) Quote Link to comment Share on other sites More sharing options...

bondango Posted March 16, 2009 Share Posted March 16, 2009 (edited) Compund charging works and works well, its getting big in deisel tuning world, and also some of the big companies like Cummins have production systems in the market. This was already tried on the Supra a few years ago, though i cant find the link...dont think it went to plan,, And i think Arnout's Compounded Supercharger/turbo charger setup never got finished either??

j_jza80 Posted March 16, 2009 Share Posted March 16, 2009 Compound charging has been around for ages. Some Aero engines during world war 2 used a super charger and a turbo together, and would go many, many thousands of miles reliably. There's bound to be alot of heat in the engine bay though. Of all the big turbo kit suppliers, boostlogic seem to be one of the better ones, and i'm sure they wouldn't risk putting this on the market without fully testing the setup.

ADL Mark Posted March 16, 2009 Share Posted March 16, 2009 Looks like a brilliant kit. I wonder if it'll fit our RHD cars though? It'll be touch and go around the steering column area.. Quote Link to comment Share on other sites More sharing options...
