tis also the one that as standard, bar a bigger towbar, towed a boeing across the runway to show what it was capable of.
also shares the same engine with the R10 race car

I thought that was the V10 Touraeg TDi

 

[pgarner]

my mistake i thought the Q7 and toureag were the same car different badge. looks to be a different engine as well

 

[Poddy]

the Q7 has the v12 from the R15

 

[HDi fun]

All this Rs Qs and Vs is getting too much for me.

I'm gonna design a V1 engine

 

[pgarner]

now i know you joking
youve said plenty of times your not willing to get your hands dirty

 

[HDi fun]

I only said design. The chance of me building it are effectively nil. My mechanical efforts stop at replacing an air filter or pollen filter element.

I did do my own work once upon a time but that all stopped years ago.

Then my eyesight started to deteriorate so I cut that out as well.

 

[pgarner]

haha ill give you a help with the designs then we can go splits on all the money we will make

my design is

/ or do you want \ instead

 

[HDi fun]

I was thinking of this > with an articulated connecting rod

 

[Vin Diesel]

In a recent road test in an Australian Motoring magazine the V12 q7 run a 13.6 1/4 mile @ 108 mph 0-60mph 5.2 sec with 2 passengers on board & less than 3000km on the speedo. Red line is 4800rpm although its limiter is set @ 4600rpm & its theoretical top speed is 170-5mph @ 4600rpm with speed limter removed. & Yes is got into the low 10Liters/100km sittin on 70mph. Imagine a chiptune exhaust etc. This is a 2600Kg vehicle in weight & scares SRT8 Hemi 300c over a quarter. Imagine the motor in A4 Sedan or the Killa looking S5 Coupe

 

[jarrus]

welcome to the forum dude,

audi put this engine in a concept r8 as well, i don't think they are ever going to make it but if they did and i had the money, I would buy it definitely

also something to add this is the engine they use in the leman racer, and in that car it chucks out over 800 lbft torque, thats enough to pull the earth out of orbit of the sun!!

 

[jarrus]

plus also i think this engine would suit the a8

 

[Vin Diesel]

Well the new A8 has the 260kw 4.2 v8 diesel & claim a 7.5 ltr/100 combined city hwy & also in the low 13s killa

 

[Vin Diesel]

yes the R8 concept is only that for now because that cars chassis is so well balanced as a supercar and that V12 Diesel is quite alot heavier that the V8 or V10 so the cars sweet handling would of been severely compromised

 

[jarrus]

Indeed, it adds around 100 kg the overall weight of the car, but i'm sure that audi wil be able to work around this and also they need a new gearbox for it because the one it currently has isn't up for the jo of transmitting the torque, i think they have been looking into using a dsg box, i reckon the one from the veyron would work quite well as it has more torque than the diesel so it can cope

also for the a8 that is a quick time but i'd still love to have that big v12 in there, I think it would suit the car quite well

 

[Yugguy]

i reckon the one from the veyron would work quite well as it has more torque than the diesel so it can cope

Lol, it'd cope but it probably costs about 300grand on its own..

20,000 for four tyres that could theoretically only last 30 miles.:amazed:

 

[jarrus]

I was just talking about the gearbox, the drivetrain is all there and you wouldn't need tyres that cost that much

 

[xpbobbiboy]

Hey mate..
Got my Range Rover Sport Remapped, went from 190 BHP to 230 and got better economy as well,, Do it !!!!!!

 

[jarrus]

Yeah, my parents have a Land Rover Discovery 3 with the same engine in it 2.7 TD
and I keep telling them to do it.

 

[obi_waynne]

It's actually silly not to remap a Turbo Diesel. You get more economy *(usually) more Torque and loads more driving flexibility.

V12 TDI with a remap gives absolutely insane levels of Torque.

hola como estas, tengo un motor nissan qd32t dentro de una chevrolet k5 blazer 1982, cuenta con una caja de 5 velocidades de nissan patrol y61 y juego de diferenciales de 4.88, llanta 33 "rin 15, mi motor es turbo y cuenta con bomba de inyeccion mecanica de nissan td27 de alta presion, quiero mejorar el rendimiento de mi motor y poder sacar muchisomos mas caballos de fuerza, me gustaria por favor que me indicaran que kit me recomiendan o que turbo, o modificaciones me recomiendan para aumentar la potencia de mi motor, muchisimas gracias, espero su respuesta

 

[calitos550]

Sí, mis padres tienen un Land Rover Discovery 3 con el mismo motor 2.7 TD
y sigo diciéndoles que lo hagan.

Hi there mate,
I ran what you've said through google translate and I got the "jist" of what you've said.
It really depends on what you're using it for really,
If offroading is your thing then a VNT turbo of sorts would probably suit you well.
As for the extra fuelling... again I'd need to see what pump it has on it, there typically 2 types "inline" and "distributor"/"rotary" are the most common usually manufactured by Bosch or Lucas.
An educated guess, I would say you probably have a Bosch (made under license by Denso like most Japanese diesels did back then) distributor type pump (Bosch VE) really easy to tweak but not infinitely adjustable because there will come a point where it wont supply enough fuel and that's when swapping and changing internals will be needed... (a whole other topic)

Hope this helps.
JJ

Hola amigo, entonces me dices que está bien colocar un turbo de geometría variable, exactamente mi auto va a ser para todoterreno, no tengo componentes electrónicos ni en la bomba de inyección ni con ecu, que turbo me recomiendas que me puede dar mas poder
