Yup, read my post, the engine in that car has had about £2000 worth of work on it, is running 450bhp and is reliable.

ok, fair enough.

Cheers pb3200

Quote from pearcy_2k7 :

I don't understand why you would want 2 turbos, just get 1 supercharger, have the engine bored out to 2.2 and over 450bhp all day long, happy days.

Just like that lol.

No one is expecting you to know about them. It's called reading. There's a huge amount of useful information out there, how about you investigate it.

Sure asking people is another way of learning, but asking such broad questions as how much power will I get by adding a turbo (or 2 turbos ) is just pointless.

Also I'm pretty sure at 15 I never had that question come to mind, however by the time I was driving at 17 I was fully aware of what was required to get a reliable 250BHP from the 2L engine I was interested in. And I didn't ask any broad questions like that, I went to a forum that was actually related to the thing I was interested in, ie Ford engines, and read what the hundreds of people there who had already done it had to say. That's how to learn.

Ok, I will start looking on websites about vauxhall engines as the Z20LET is a Vauxhall engine. Well a GM engine as they are owned by them.

Quote from wheel4hummer :

If you want a RWD vehicle, just buy one that's already RWD.

Very true lol. When I become old enough that insurance wont be so high I will buy a rx7 as I think they are really nice cars.

One thing I have to say is that I am 15, why would I have a good knowledge of how turbos/superchargers? As soon as I get a car I will start getting a understanding on how engines work.

A Z20LET is already turbo'd but obviously being a factory turbo it isn't going to be the best.

Quote :

or that he thinks converting a hatchback with a useless rear suspension to rwd will be in any way easy

I like the way you said I would do this to a hatchback.

I am going to start researching, anyone know of any decent books. I think my best bet would be Google though.

Quote from Osco :

start with decent tires perhaps? :hide:

I have already said that. It's the most obvious.

Quote from Christopher Raemisch :

To get power down on a FWD you need LSD, preferably one that never actually 'locks' like a type of unit Quaife makes for my car. You will then need solid motor mounts to take away the 'slap' that happens with stock mounts as the engine is rocked back into the mount on acceleration.

I see. So would need better engine mounts, LSD. If I do tune a FWD, I will be getting a better suspension, better breaks. What else would you need to get better handling? Anti-roll bars, what else?

Quote from Shotglass :

someone needs to get tristan into his normal mood... i still cant understand how he could post in here without ripping him a new one especially when hes asking for it as much

Why, I am asking questions about how to do things. I am wondering how you would do certain things. Like how to get power down in a FWD which would most likely be difficult to drive with too much power, how to convert a car into FWD and how twincharging works. If I am asking questions in a mature way asking on how to do things why would I need to be ripped. I am wanting to get on with Tristan now and I want start an arguement with him now, I will take in with what people say who know what they are doing with cars and how they work.

Would it be able to out pase a Veyron on acceleration? I don't know the top speed of this CCX-R. It is better looking then the Veyron though without a doubt.

Quote from Osco :

FWD and power delivery should not be mentioned in one sentence

Lol, if I had a FWD car and wanted to tune it, I would most likely convert it to RWD or 4WD. How hard would it be to change a car to RWD. Wouldn't you have to change the propshaft, put a diff on the back. What else would you have to change? Gearbox?

Quote from Christopher Raemisch :

If you had to guess that doesn't sound too far off. I have a 2.4 that runs 1 bar of boost and makes between 230-240.

I agree nobody needs more than 125HP for a street car, but where's the fun in that? =)

125bhp is fun for old people lol.

Quote from wheel4hummer :

Well, you haven't even said what boost level it would be running. For a two liter engine, I'd guess 1 bar of boost to make about 240HP or so. That is just a very rough estimate though.

ok, don't know what boost. Too much boost can just make your wheels spin though, cant it? A realistic boost figure. Also how would you get a FWD car to deliver the power. Good wheels? and would the chassis need some work.

Quote from wheel4hummer :

Anywhere between 0 and 500HP. I mean, how do you expect anyone to answer that? And it depends what pressure ratio(s) the turbocharger(s) / supercharger would be running.

I was asking for a rough estimate that's all.

Quote :

impossible to predict, like w4h said, anywhere between 0-400 bhp

Ok. Wouldn't having two turbos, one smaller and one bigger produce anything from 0-300/350bhp because they dont produce as much power as a supercharger do they, I would of thought they dont.

What parts would you have to change with the engine? With a supercharger you would have to get a better cam and get a intercooler wouldn't you? But what would you have to change with having a two turbo's? Would you still need a intercooler with a turbo?

Quote from wheel4hummer :

Anywhere between 0 and 500HP.

300bhp from two turbos or a supercharger with a turbo. Seems a bit untrue to me.

So say I got a Z20LET (200bhp stock) and done either one of these two to it.

1. Smaller turbo and a bigger turbo. What would be the final amount of bhp achieved?

2. Supercharger and a turbo. Again, what would be the final amount of bhp achieved?

Now I want to know what happened next...
Did the monkey go?
Did the monkey hurt the dog?
Did the dog hurt the monkey (unlikely)?
Did the dog scare away the monkey by chasing it and running? (unlikely)

I think it would be unlikely for the dog to of scared away or hurt the monkey because how much stronger a monkey is then a dog.

Quote from S14 DRIFT :

Would need more than just a turbo: You would probbably have to sort the fuelling out, change the compression ratio, etc etc, if your turbo will be adding 100bhp, it's probbably more than advisable to get an intercooler as well, as all of these non intercooled turbos (on Audis and some Vauxhalls) only add about 35-50bhp, probbably even less.

I know you would have to do more to it. How much would it cost for a intercooler, supercharger, turbo and the other mods that would need to be carried out to get the most from the turbo and supercharger? About £3k-£4k?

I seen the Range Rover Sport Supercharged version actually accelerate properly yesterday, those things are quick for a 4x4 so a supercharger alone should add a lot of power, correct? A turbo is just there for higher revs?

Quote from S14 DRIFT :

Google Volkswagen Golf GT.

It's a 1.4l engine with a supercharger and a turbocharger, kicks out ~170bhp and returns 35 miles to the gallon. It's the way forward imo.

That is a lot of power out of a 1.4 So a 2ltr Z20LET engine that produces 200bhp. Put a aftermarket turbo on it and a supercharger and it should be near enough 300bhp wouldn't it?

I will have to look up on sites to see how it works. Thought I would come here first because I knew someone would give me a answer. I will look through google to see if there are any websites that give you more of an inside look into how it works and what the results can be.

Quote from Bean0 :

I am aware of a few different types of multi-charging.

The old Lancia Delta rally car had super and turbo chargers, as far as i gather the super charger was basically a way of upping the power whilst the huge turbo was still spooling up. I've also heard rumors of the old 205 T16 using Nitrous as an anti-lag early in the revs...how true this is I have no idea.

The twin turbo jap-mobiles I saw years ago in Max Power used to have a smaller turb and a larger turbo. Obviouslt they spooled at different rates, and the smaller one gave boost at lower rpm whilst the larger one gave more affect at higher revs.

Thats what they was sort of saying on the site I saw it on. It said the small turbo was for the lower revs and then the bigger turbo took over after it spooled up. What do they mean by spooled up, does it mean that whilst it was like booting up? I thought turbo's didn't kick it to about 3,000 revs but a supercharger is always kicked in.

Got to add this to the christmas list. Looks a really good game. What actually happens on the cruise mode. Is it free roam or do online players get together and just cruise around?

I have never gotten into midnight club as I played the first one when it came out and hated it. So never really thought the other was going to be that good either, but this looks amazing. Pitty I currently dont have any money to my name else I would go out to town as soon as I could and buy the game, looks a lot better then NFS. NFS is ok when you are in the mood but get bored after a while but this looks like it is at a whole different level.

What cars are in the game? Any 4x4's, normal day to day cars and also what exotic cars are in the game?

Just reading on the net and see that some people put a supercharger and a turbo on their engines, the turbo is used for low rev power and a supercharger for more power at higher revs. Is there much point in really doing it? I would of thought it would be expensive to do.

I also read that when modifying your engine to be twin turbocharged you can put one big turbo on the engine and the then the other would be a small turbo. I heard they do it to try and stop turbo lag as the small turbo would power for low revs and then the big turbo will take over at higher revs to try and beat turbo lag. Does it actually work.

Could someone who knows a lot about turbocharging/twincharging a engine actually explain to me why it does or why it doesn't work please, I dont really understand it as the website that it was posted on didn't actually say how it works or if it does actually work.

I am not attacking you what so ever. I know you are sharing your finding what you do a lot, but you have said your self you are a little strange so I was just wondering. Didn't say it to cause offence, just wondering

Lerts can I ask what do you work as and what does your daily routine? Do you just read things and then make your own version up? Or do you have learning difficulties?

Quote from Jakg :

So far i've been looking at this:



But it has to fit in here (which is a single DIN slot with a gap underneath - it's just a single DIN headunit with a double-dint front)

It should most likely fit in there, you just need to buy a blanking plate to cover up the left over space.

Yes on engine front, but :S, why would they setup the car for 4th/5th place... lol...

Because that's all they needed to get for Hamilton to win the WDC. Racing for points instead of going for the win.
