Volvo 2.0 240 twin supercharged and a turbo, ????

I like the nice ford v6 personally but ive been looking at all the projects that have been posted and a personal favorite of the swedish seem to be volvo's!

I dont want to sound dumb, but the video below i dont quite get, the car have twin superchargers and they need to be connected to the air plenum, so therefore the throttle body controls for much air they get but if your running the 240 throttle body there is no way that you could get enough air for the engine and 2 superchargers?? is there?? so how do they do it? do they run 3 linked throttle bodies?

anyone seen this car before?

and my other question is turbo spool at certain rpm depending on size, and superchargers are constant boost as they are belt drive, so why dont people use both? is there a disadvantage?

and are these volvo engines very tunable?

thanks for the knowledge, i hope you can help.

I can't actually see the plenum, but it looks like it got the original TB, but it should be enough. Since you are compressing the air, you do not need a big TB. Compressed air takes much lesser space than regular, and of course it pushes the air, not pull it.

Not seen it before, but it looks nice! Overkill with dual superchargers. One would do great for low hp and then a bigger turbo for the upper hp.

The problem with both is that you need to build it in a s special way. The charger is better on lower rpm, and turbo on the higher. If you don't let them work apart from each other they will take out each other. So you have to build a valve system so the charger starts at low RPM and then the valve system switches to the turbo on higher RPM.

that car is awesome but come on 2 compressors thats crazy.

can someone help with uploading pics? done a little sketch to try and make sense of it all

you guys tell me if im right.

ta

Why would you want a supercharger? There is many disadvantages with it

1. Powerloss
2. Expensive
3. heavier
4. space-consuming
5. Silly

thanks for the explaination grey!

haha mikael your so black and white about these things, love your turbos and think chargers are rubbish haha

but.

1. power at lower rpm and no lag
2. cheaper (in the UK) obviously depending which supercharger you buy, eg. eaton are cheap.
3.ok heavier i agree
4. i think they take less space than turbos, chargers hug the engine a lot more.
5. silly? depends which side of the fench your on! they have there advantages. drag cars use more chargers.

disagree?

No it´s you englishmen that are stuck in the old ways I like to go forward nog backward

I build my cars for power, not to drive around with a caravan. You should read this https://skogenracing.editboard.com/english-forum-f12/scottish-drift-capri-t4783-75.htm

I agree with Andrew, and you don't have to be stuck in the old ways just because you like superchargers. Why? Because people are different. Turbos have been around as long as superchargers (first patent for a turbo 1905, first supercharger patented 1902), and it was also used in the 60th on production cars.
But all right, if you only want pure HP then the turbo is your way. If you want another way with pure power over the whole RPM scale, like a NA aspirated car (like tuning a V8.) then a supercharger is one way (or getting a bigger engine).
Two superchargers at once is often used if you can't have one big supercharger because you cant fit it, but combining 2 superchargers and a turbo is just dull. You will never in any way get out the benefits of having two superchargers and one turbo...
One turbo and one supercharger, yes. Two superchargers and one turbo, no!

Anyways, look at this.

It's almost nothing but it still is something.

Englishman in the past? i cant remember any swedish drag racing champs, can you? haha

i think them both, and they both serve there purposes.

thats cause your cars couldn't pull a caravan, they would have to get on boost, atleast superchargers pull like trains, i could pull mine. haha not that i have one

do you recon a big supercharger of a v8 could be powered by ford v6?

Nice facts grey, ive got one for you. lancia were the first company to ever supercharge and turbocharge the same engine.

2 superchargers 2 turbos? yes , no?

ive seen all those vids before, i tell you something i do no 2 companies, i use one. they are great guys and great prices and the other i thought was over priced. but they can make v6 dreams.

Ade building the capri, i do follow him i actually followed his progress in classic ford until i found he was on here, saveed me 4.50 a month in magazines.

thanks guys

And i never heard about any succesfull english dragracing champ but i can name some swedish. Micke Kågered, susanne callin, monica öberg, fredde fagerström, adam flamholc and so on.

In case you have missed, the americans have begin to experement with turbos and the cars are so powerfull that supercharged engines dont stand a chance. In fact they banned turbo in several classes because of the enormous power the engine get with a turbo.

WHAT!!! aha andy frost and john sleath are europes fastest and quickest cars, about 1 yr ago john sleath took both titles but now andy frost is making red victor 3 to go after the worlds fastest car. have a look its some serious stuff. chevy v8 + vauxhall victor = serious stuff

but i have one serious flaw in my arguement they both use twin turbos aha

but altered dragster and top fuel use chargers.

i like both, no grudges here!

And you know of the because you are english, and the same way around with the swedish dragracing scene. I don´t think many know the names you mention, i have never heard of them

There is many rules around topfuel, no turbo are one of them.

have a look they are cool. do these volvo 240 2.0l engines have expensive parts in sweden? are the engines sort after?

Most common is the 2.3l with 8v, but people more often use that engine block with the 16v head, instead of the 2.0l block. Parts are cheap and easy to find, and you can get 450bhp out of the 8v engine, but with the same amount of money on a ford 29er, you get the same amount of hp, but with a better power curve.

whats the 16v head off? and volvo engine with a 16v head usable? that vid i showed you was a 2.0 240 engine and that was 600hp and then went to 1000hp. volvos in england are dirt cheap but i cant find any parts for them, like rods or pistons etc.

ive looked at projects and there parts are usually from motor nord.

the 16v engine is called B234(2,3l 16v)
as Grey says most people build in a 2,3L engine and go from there or make them even bigger 2,5l and 2,6l

those volvo's arent to expensive which have the b234, volvo 740/940 gle from 1989 to 1993

does anyone know any companies that sell parts for them, out of interest

Depends on what you want.
There are several companies that is specialized in Volvo parts, I.E. KG trimning (http://www.kgtrimning.com) and Sten Parner (http://www.stenparnermotor.se) but if you want cheaper clutch, gaskets, flanges, turboexhaust manifold and things like that you can speak to me.

www.bakaxel.se clutches and diffs and some other stuff.
www.klracing.se alot of stuff

cheers guys, thanks for all the help and thanks grey i will remember that incase i need anything cheap!

those guys at klracing are crazy they have some seriously nice cars. but why is mikaels car on there?

thanks again.

its the care they have sponsored, and are in some way involved in..

the ford is "our" projekt car on skogenracing, not Mikaels own car.. if u mean this one: http://www.klracing.se/index.php?page=ford-sierra

oh, so is that not his car? so skogen racing is trying to make a name for itself in the drag and drift world's then? I just thought you were a group of friends who did it all for fun.

oh grey - tried to comment on your compressor topic but kept logging me out but found a load of vids.

it was a contest Bilsport.se had in sweden that we entered with that car and won..
this is the car: https://skogenracing.editboard.com/t5941-skogenracingcom-bilsport-projekt-50k-vinst-bilder-fran-resan

sold to one in our crew now.

enough with offtopic now for me =)

awesome, thankss for all the information anyhow.

cool cars

b234 engine ive found, like i said 740/940 gle from 89 - 93 but what engine / car do you get the 16v head from? and is it a straight bolt on for these engines?

found this aswell, thought it was cool http://www.mobeck.com/mt/NergaardMotor.asp
