Ok,sounds reasonable...if you go too small a turbo to eliminate lag then you miss out further up the rev range .... guess there's pro's and con's with all this. Mind you,most of my logic here is dealing with drag car's where 10ths of seconds count. A cruiser wouldnt be too quick down the quarter...
turbo lag is not inherent eh? how can it not be????....being how it takes time for the turbo to spool up,exactly the same on an aircraft turbine,you ALWAYS will have SOME lag to a degree...Although most of this talk is irrelevent on 4X4's ,on a drag car it applies.
anyhow i think my questions...
""The exhaust side of a turbo is a turbine not a compressor""---- that is correct but we knew what he was getting at.........
a supercharger manually drives a compressor.So in effect it does the same as a turbo but mechanically driven and provides instant power without turbo "lag".
Thanks GZERO for your last paragraph.I definetly understand how turbo's work but they way you worded your last paragraph on pressures makes a lot of sense.
Rodd- i can understand that bov's arent for everyone!...dunno why but im my 30's and i still love the sound!.I also have a 12H-T...
well, its same as wastegate but sounds better! It actually does keep the boost up though by virtual of the fact that it keeps the turbo spinning freely during the gear change.
oh well--- it's just the R34 skyline in me !!!! ;)

To bring it to the same level as a low compression engine!.I was having a comnversation with a friend on a fishing trip over the weekend and this topic came up.Im trying to make sure i have the answers next time i see him.
Im not...
ok cool ,ill check the how stuff works section....im quite familiar on how they actually work though--studied aircraft gas turbines during college,same principle.
thanks

Hi fella's,
I have been wondering for a fair while now,why do you need a low compression engine with a turbo? :confused: .I know people put them on standard compression cars though.
I just cant figure the logic in my head seeing as how a turbo increases the compression anyway ........what...
I have a HJ61 sahara....my car has the light/sunroof panel but not the drop drown section that the picture has,,,Although i quite like that design!.
Rod, can you give me an idea of what youve made for yours because id be interested in doing the same.
cheers
Darren
