this may be a silly question!!!!!

you people who go for the single turbo route, why, , why don't you just stick with the 2, but 2 massive turbos instead of just one???????? i suppose if it could be done you all would be doing it i guess ha ha would just like to know if it could be done, and if not why???

i have always thought that, but never asked!

it's cheaper to do one mate and you get the same power me thinks .

Its been done loads of times. Do a search for "Big Twins"

i may go for 2 on my n/a:)

this is probably one of the few sites you could search for that and not end of feeling slightly ill!

Lol was thinking of something witty to add to my thread but brain not working.

mmmmmmmm i think your rite there dude

got 15k in your back burna

Easier to tune too, less weight and fabrication of pipes required.

The less weight argument point is always killed when the car in question has been covered in superglue and ram-raided through Halfords though...

Hehe true.

didnt know we were talking about pulsars!

Here's a daft question. Can big twins be run sequentially? If not, why not?

I think the HKS twins run sequentially, the 28/35 ones. I also think they are expensive.

I don't think so mate. There's VERY few large sequential kits on the market, and none that I think are openly available (ie they all seem to be custom made)

The benefit's of a big twin kit verses a large single kit are a bit blurred nowadays. The problem being that most big twin kits use slightly older turbo's, and the newer single turbo's can produce the same kind of power but at lower rpm's than the used to be able to.

To kinda sum up the theory though, twins should be able to provide a similar amount of airflow, more efficiently than a similarly rated single. (ie two turbo's doing less work each - similar to why we have twin turbo's as opposed to a larger single from stock) so should either create more airflow lower in the rev range, or give more top end depending on what spec of turbo you went for.

The added weight, hmmm I guess my extra turbo will weigh in with manifold and wastegate at something like 20Kg's (worse case, and I am rubbish at estimating weight) more than if I just ran a single. When you put that into the perspective of a 15-1600kg car, it's water off a ducks back. Especially as they still weigh I would guess something in the region of 30-50% of what the stock system weighs (again bear in mind my inability to gauge weight!)

The problem you have is cost. A twin kit new will cost in excess of 5K + fitting (easily see another 2.5K on that) whereas a similarly rated single would probably chime in at 5K all in.

Hope that helps!

better to have one small turbo, and one big one next to it;)
