i do however have a solutiuon to your problem,

couple more lines should do it

now my boss to cure the lag on his 911 turbo has a nos system with smart controller
basicaly nos is only used at low rpm and as soon as the turbo kicks in the nos fades out
but thats a flat 6 not a inline 4 pot tractor engine :lol:
ive got a answer aswel mike
v8gm derv :lol:
who was it with the propane injection mike ?? white90 ??
ian report back on the VNT, dont no a gr8 deal about them tho really
my minds swung to to little doddy turbos working together via flapper valve in manifold like a vetus watever it is :roll: forgotten now and i work on boats :oops:

the new vw golf GT has a 1.4 engine thats both supercharged and turbocharged - pushes out 170bhp.

need a decent pulley set up to run the supercharger from the crank pulley.

Steve lloyd used to run a 90 with lpg injection but i think it was a 300.Went like f*** though :shock: .Looked at doing it to mine but in the end just went mad with fuelling and boost

was just about to make a poke about LPG.
fantastic performance boost on diesels. burn about 95% of whats in your bores rather than about 40%. easy answer if you are that desperate for more go.

extreme90 · « **Reply #37 on:** February 01, 2007, 21:43:17 »

no i aint really after more power 2BH simon the 200tdis with full width cooler has more than enough power and im sure you'll agree
just thought it be funny to have summat stupid bolted to the engine :lol: whilst still experimenting to see the outcome

simonred90 · « **Reply #38 on:** February 01, 2007, 21:47:47 »

in that case then, gas, permanently. possibly a 5th injector (on a max throttle switch) but you may have troubles with it knocking low down in revs.

extreme90 · « **Reply #39 on:** February 01, 2007, 21:51:31 »

no was thinking twin turbo :lol:
besides i got more spare 200's than land rover have :lol:
im race building one :lol:
everything balanced measured cut down steams everything
and gonna put that into a std road going 90 with full width cooler and itll go like a rocket :lol:
i cant wait :lol:
dont think it be so good towing tho :?
:P

cant see why two turbos. wont spool up as quick as one. and you'll only run say 25psi peak with modified crowns. be as well with a hybrid T25. spin up at mega speed and still be just about on limit of 25psi. would be sweet like that thinking about it....

Xtremeteam · « **Reply #41 on:** February 01, 2007, 22:00:33 »

but at 22-25 psi the head gaskets only last about 2.5k or a month or 2 :lol:

extreme90 · « **Reply #42 on:** February 01, 2007, 22:06:15 »

no
1 big 1 small turbo

just the small 1 running at low rpm, and quite litraly at 800rpm itll be spinning up
look under the bonnet of a new ford fiesta, 1 small turbo...spins litrally AS your pulling off

but 1 doddy 1 wont provide 1+ bar flat out only around half a bar
thats where the 2nd bigger one comes in

so small low speed so getting pleanty of boost at 1100
high speed keep my normal boost pressure

there is a car that runs this set up but i cant for the life of me remember what it is

Wire ring the block and wind the boost up to 30psi and get some stronger head bolts made up so you can torque the fcuker down abit more too :shock:

extreme90 · « **Reply #44 on:** February 01, 2007, 22:39:13 »

:lol:
studded

lenrover · « **Reply #45 on:** February 01, 2007, 22:44:30 »

do you reckon the pump could be wound up far enough to provide enough fuel at 30psi?

How cool would that sound :shock: :shock: 8) 8)

be some nice clouds of black under load too ooh I love diesels running lots of boost 8)

Over fueling just a wee bit there then? :lol:

Such a nice sport. not too keen on the turbo lag though seems you a have to rev them to a few K before owt happens. But then thats what happens to big turbos.

I'm with porny on this one a VNT is the way to go.

It can with bigger internals

Supercharging.... is ok but does sap power. And I donÃ¢â‚¬â„¢t think it would work with a v belt, most require a serpentine belt.

Twin turbo, lots of effort and need to make sure you don't over speed the smaller turbo... sequential turbo's are nothing that new. But will require a custom manifold, and youÃ¢â‚¬â„¢ve got the problem of packaging.

Packaging wise, a VNT makes more sense.

Boost pressureÃ¢â‚¬Â¦ youÃ¢â‚¬â„¢ll find the rings and pistons will be the next weak point. A wired block (as already mentioned) will make head gaskets last a bit longer.

If you try to run more than 17psi on a T25 it becomes very inefficient, a hybrid is slightly different, but not much.

ah, compounded turbos, sort of scanias 14L470 motor. real nice for pulling heavy loads. now i see...... thinking

Is it I belive that a stadard TDI turbo can go to about 20 PSI then it actually restricts it self as it can't spin any faster. Also thinking about it what happens when you shut the throttle off OK a Diesel as a wide ope throttle (i.e. no butterfly) but surely the boost must go somewhere and so would it take a little longer for the engine to throttle back? Else would you have to think about a dump valve to help rid the system of the pressure?

disconected the wastegate on my tdi to race a saxo & it pumped out 24psi o boost, smoked the shaxo & went of the lights spinning the wheels :lol: :lol:

Dan,why not try a merc slk supercharger?nice little unit,self contained and both inlet and exhaust on same side so it would be easy to put onto a 200,would just need a pulley making(or several different size pulleys for different BOOOOOOST :shock: )
Just a thought :-k :oops:

On the subject of dump valves,can one be fitted to a tdi?.If so how does it get a vacuum :?

extreme90 · « **Reply #57 on:** February 02, 2007, 22:41:00 »

yea they can, but its a bit pointless on a tdi really expecialy with a full width cooler
dump valves work best on petrol afink

Yes but they sound cool :oops:

Xtremeteam · « **Reply #59 on:** February 02, 2007, 22:43:50 »

dump valves on a tdi is so easy

need a dump valve,solenoid valve (12v) & a micro switch,
