lets nock it around the room
been thinking for a while :lol:
turbo on mine kicks in at around 1600ish so anything below im a N/A
:?
so how about a extra blower :lol:
supercharger for low down revvs and then the turbo kicks in higher up the rev range, so ive got constant power not all or nothing

ino some years back nissan did this to a micra 800cc only a few were made, and a 911turbo couldnt keep up with them :shock: , and i aint joking niether,

a dear freind of mine who restores porsches as a living told me about them today and it got me thinking :?

just seein what you guys think :lol:

YOu do all the development, tell us all about how wonderful it is, then we'll all be doing it!!

There's no reason why it shouldn't work, but fuelling might be awkward with a normal pump, electronic injection i suspect would be better, but the thing i like about my 200 is how simple it is...!!

yup

to have a constant even amount of power, not abit at low down then [mcuk] off at 1600 and above
higher real low down torque figures ect ect
afink im gonna rack mr porsche brains tomorrow when he nips in

afink am gonna pay apracing a visit tomorrow night and pinch that supercharger that he offered me for a ride out in me 90 :twisted:
and then fettle with the dead engine on the bench :twisted:
playtime :twisted:
just linking it all together :?

cant be tooo hard danni come on!

wat you thinkin of takin the suercharger off? how big is a mini one?

Disco-Ron · « **Reply #9 on:** January 30, 2007, 22:33:29 »

I think the Mini one would be too small, they're only 1.6ltr, and it'd have to be capable of flowing enough air to feed a 2.5ltr diesel at pressure..... even with a tiny pulley on it i don't think it's work, you might end up with the blades spinning so fast they don't do anything at-all.... (there's a word for that that i can't remember)!!

no need. tweek your motor just right and you'll have nearly all peak power on tap at almost instant response. my truck doesnt smoke for no reason!!!
and too much will just rip your drivetrain to pieces!

extreme90 · « **Reply #11 on:** January 30, 2007, 22:34:52 »

errrm this charger ive been offered was the one off his 2.8 capri that he races with :lol:
he changes um every 5 months afink he said :roll:
cant remember now
:lol:
its not small so should be interesting at the pressure it pumps out :roll:
early stages yet, alot of work involved not as easy as it sounds theres alot of fettling involed

thats why 1 ive got mine tuned and mine produces a touch of black smoke :roll: honest only a touch :roll: :twisted:

and i keep a week link in the drivetrain

and another thing :lol: :lol:
i aint bothered :lol: :lol:
its got to be worth doing just to see the outcome, its not for onroad its to bring more avilable power offroad
hey if it dont work it doesnt work nuffink lost
if it works it works
2 options :lol:

Surely a hybrid T-28 with a smaller comprssor housing , cut back blades,and 360degree bearing would give more poke lower down sure you'd lose maybe 3-5bhp at the top of your rev range but thats not really important in an off roader is it? especially a 200 where most of the grunt is delivered low down?

burgerman · « **Reply #16 on:** January 30, 2007, 22:54:39 »

Here is my thoery --- But before i start , I know in the jet ski world if the impellor spins too fast its called cavitation, Not sure if its the same for air related masses ??

Anyhow, I digress----- I would say that a turbo charger sucks in as much air as needed in an increasing amount (as the boost rises) And a supercharger is set to increase in a steady increase, ---- so if a supercharger was coupled up to a turbo i reckon there would be some serious fuel/air ratio problems, something like an initial surge from the s/charger but as the turbo spins up and asks for a huge rush of air , the charger would not be able to supply, But i reckon a variable pulley on the charger could sort it out, But then were getting very serious indeed, Any how its just my thoughts, if someone blows them out of the water so be it, I have plenty of other thoughts in there to go yet. P.S i did bring this type of question up at a visit to jaguars HQ when i worked for them, the question was Kinda like why does the "normal V8 have VVT (variable valve timing) and the supercharged one doesnt ?? Didnt get a proper answer though, So i made up my own thoery/thought as stated above

extreme90 · « **Reply #17 on:** January 30, 2007, 22:55:21 »

ive looked into it a touch, but even so the roller bearings still have lag in them, not alot but they do
what i want to do is cut out the delay between off boost and on boost
options...
supercharged low rpm...turbocharged high rpm
twin turbo, 1 little doddy turbo of a new ford fiesta and a std lr turbo..
little turbo on boost at idle rpm :shock: big turbo interveens when max pressure achieved by little turbo

or just 1 little puney turbo that is already spun up at idle rpm
so the slightest of throttle and youve got boost

i dunno, its a whole new can of worms with endless options

or to hell with it and fit a gmv8
all the torque youll ever need at idle rpm :shock:

Anti lag? dunno how do-able it is on a diesl but its bound to result it big clouds of black smoke and boost noise- 8) 8) 8) 8) 8)

cavitation is when you get air pockets trapped inbetween the impellor, so it revs up and you get no where cos its moving air instead of water
like a clutch slipping on a car
likewise with outboards/sterndrives with propellors, throw it into a to tight bend it traps air and engine scream you get no where :lol:
sorry work on boats :roll:
back to thread :roll: :lol:

extreme90 · « **Reply #20 on:** January 30, 2007, 23:08:36 »

if it works on a 800cc micra itll work on a 200 :lol:
the main theory behind it to keep it simple is to cut out the delay between on boost and off boost
as you accelerate, you start moving then there that sudden kick from the turbo....right ?......the aim is to get rid of that
ill speak to the porcshe man t morra and report back

as ino his own personal 911 has this system and it works

Xtremeteam · « **Reply #21 on:** January 30, 2007, 23:09:28 »

what exhaust u got on yours btw?

got a free flowing system on mine & it spools up no problem & quickly

What about the VNT that is found on the HS 2.8?

I think all I can say is dribble.
Seriously tho, i'd love to get more power low down with the work I do on mine, but I have it tuned currently for max power on the road, would be nice to have maybe a twin turbo setup, I dunno...

Porny · « **Reply #28 on:** January 31, 2007, 10:31:48 »

As already mentioned....

Go for a VNT!!!

I've got one to go on my 300tdi at some point soon!! :twisted:

Antilag on a deisel..... now that *should* be interesting. If you've seen a performance petrol doign it you'll know about the loud crack and flames. On a deisel, probobly not gonna acheive a gret deal and produce mushroom clouds :)

I have heard of NOS being used to do Antilag, I'm not convinced that would work on a deisel. The Ottinger/Ralliart system uses a combination of a solenoid to wind the trottle wide open and a injector before the turbo.
