top mount turbo are more better?

as above^^^ just placed it to see how it looks what does the benifits of top mounts best wastegate location?

Don't think so man, i just bought mine as i thought top mounted turbos look the dogs, now im getting bored and wouldn't mind swapping for a ram horn style but i guess its just personal preference tbh.

Well in theory you should get more power having the turbo higher, but you wouldn't notice any difference -) You will if you drive 2K miles above the sea level -)

Consider it as a joke! What I was saying that turbo have more bhp when on the high altitude - ever wondered why so many planes turbo charged?

that is completely wrong. at higher altitude you will loose performance as the air will be less dense. whether the car is turbo charged or not makes no difference. and planes arent turbo charged in the same sense that a car is. they use a jet engine which is essentially a massive turbo as it compresses air, but the similarities stop there.

well i dont have a kit im just asking if i go for it i need first what route im going ex top mount or ram style before i tell someone to work it ,i have seen manifold such as racetech what materials did they use?

ah sorry misread it lol

but without being to much of a nerd you actually loose power the higher you go as the air gets thinner. alot of the piston engined WW2 planes were turbocharged or supercharged is because if they weren't they would loose alot of power at higher altitudes so they fitted a charger to compress the air and give the similar power at higher altitudes that they got at sea level

you can actually measure a power loss in a cars engine for altitude. when working out compressor maps for turbocharger altitude from sea level plays a bit part

cheers tim for the help i think i will go normal route something simliar to the picture i posted of the racetech manifold

oh i didn't mean that in regards to a top or bottom mounted turbocharger. i was more talking about altitude and how it effects power production. but to answer your question there shouldn't be any difference what so ever in power from a well designed topmount to a well designed bottom mount turbosetup

Mate you're actually right! I knew that it's better to have a turbo charged car on the high altitude rather than supercharged or N/A, but didn't realise that they lose some power as well..... does that mean that all the drag racing must be in Holland? one of the countries below the sea level???

Altitude effects
A turbocharger remedies this problem by compressing the air back to sea-level pressures; or even much higher; in order to produce rated power at high altitude. Since the size of the turbocharger is chosen to produce a given amount of pressure at high altitude, the turbocharger is over-sized for low altitude. The speed of the turbocharger is controlled by a wastegate. Early systems used a fixed wastegate, resulting in a turbocharger that functioned much like a supercharger. Later systems utilized an adjustable wastegate, controlled either manually by the pilot or by an automatic hydraulic or electric system. When the aircraft is at low altitude the wastegate is usually fully open, venting all the exhaust gases overboard. As the aircraft climbs and the air density drops, the wastegate must continually close in small increments to maintain full power. The altitude at which the wastegate is full closed and the engine is still producing full rated power is known as the critical altitude. When the aircraft climbs above the critical altitude, engine power output will decrease as altitude increases just as it would in a naturally-aspirated engine.

Easier access to the turbo/ oil drain/ all bolts. That is the main benefit of top mounting the turbo.

^^^^ staying on topic....i agree with this. also down to personal choice. me personally like to show off the manifold...so i like the traditional style manifold. a big turbo can be seen well..whether its on top or bottom...but a manifold is a work of art (for me)..i like it to be seen :)

i will go for normal cos that turbo will pill the paint off in that position with heat is it necceasary to heat wrap an s/s manifold ?
