crazy power
Turbo Mini Forums

this might sound stupid but has anyone tried to twin turbo the a series, or at least put on a twincam head with a turbo etc, surely theres more power to come, was looking at garage delta's mini, we give them an a series and they get 210 bhp N/A!! we should see what they get out of turbos but they'd probably have to rebuild it everyday! just wondered

its not so much what you can get out of it... its what ou can do with that power!

Have you driven fast mini? 120bhp is starting to get very fast for a mini!

Then theres the relaiblity... sure you can get more out the engine, but for how long?!

One idea I looked into ages ago was running a 711 crossflow block on a mini gearbox with a Lotus Twincam head. The whole thing weighs in at about as much as 1.5 A Series. There was another guy in Cornwall who emailed me about another project who was going on about using a 16V zetec engine (alloy block one?) and reckoned it was pretty much a BDA but reliable. I think a 5 bearing engine is the go. From what I read about the gearboxes, a good build will see it reliable. I would a mini's cornering ability to remain the same, hence big stuff is out of the question, as is RWD. These bike engined jobs are better off in a proper chassis. You're getting into the territory of losing the whole mini engine, I suppose you could go Honda or Vaux, but they generally involve buggering it about so much it loses most of being a mini.

When I've sorted my 2 out, I'm leaving it there for kitcars.

Bugger off, I'm getting there.

Who the **** is garage delta?

And are you saying they have 200+hp from a nat-asp A-series with a 5port head?

300hp would be very easy with a 7 or 8 port head, forced induction and ?????

would like a link on this if poss

anyone please

GARAGE DELTA ????

its in mini world along with stuart's turbo (which is obviously better) it uses a special alloy jk head with four motorcycle carbs, any ideas on a twin turbo, for instance if you had two t2's would this give better power than a t3 but less lag or would it make no difference as the exhaust gases would be split, would dellortos do the fuelling i hear webbers are not good for turbos because of the inreased pressures.

i heard the whole point of twin turbos is the 1st smaller ones help the big one spin up so get more turbo between rpm range and less lag or is that bollocks?

depends if there inline or seperate maybe you could have 4 inlets with a turbo for each, i've seen a chevvy with 8 turbos that was mental!

benross search for garage auto delta on google, the site is in japanese so you need to find some kind of translator ].
as said above the car was in mini world,
it is absolutley insane and is full of some really top mods.

Anything you want to know about delta let me know, I build there mini engines and supply them with modified BMW mini heads, There a great company.
If you want to read there website use bablefish to translate it.

Ask yourself? why do most championship winning minis use morspeed?

Link to the site would be helpful..

Two things are infinite: the universe and human stupidity; and I'm not sure about the the universe.

We call our hillclimber the "Twin" Turbo, but that is be cause me and Wil are twins, we do get asked now and again if it has 2 turbos as there is a sticker on the back.

I think most twin turbos exist because the pipework is easier. i.e on a V or a flat engine it is easier to plumb in two smaller turbos, one for each side, than have exhausts all over the place.

A man without a project is like a like a woman without a shopping list.

i think the new jag diesel has got this sequential turbo idea to

An a-series would really benefit from twin Garret T1.0 turbos... Do they exist? Not a clue...

Basically, If you can do the job effectivly with one turbo, going for two smaller units won't neccesarilly be much better. Certianly in our case, when (one of) the smallest turbo out ouf garretts book is suited to our application, there isn't a lot of scope to go smaller...

For the 5-port, I'm not convinced you'd get it to work properly, the exhaust pulse cylcle and shared inner port makes it unfeasible in my mind...

For me, an A-series is only really an A-series when it's got a 5-port head...
If you took a pinto bottom end and stuck a sierra cosworth head on it, you can't still call it a pinto, and vice versa.

well i am going to put a chevy V8 in my mini with 5 port metro heads and call it an A series..

I think?.

That car is amazing, a real work of art.

think that some subaru legacys are twin sequential turbos. Mate of mine had one imported that was called a "B4" it had bilstein suspension and two turbos, with a valve that changed over at higher revs to the big turbo. It was an awesome machine.

His best story involved racing a Porsche on the motorway with his wife reading the paper, his two kids asleep in the back and his labrador in the boot with a suprised look on its face pinned to the tailgate under acceleration.............

going back to the delta mini, god only knows how much theyve spent developing the engine, if we had that much to spend on one im sure we could get well over 200bhp quite easily, and remember its a race car so it would not be that great for road use

roughly how much would one set us back engine tuner?

I know of one of those heads for sale at the moment if anyones interested. Its on a nice midget lump at the mo and the owner wants to sell as a complete package. Its built ?(well pretty much) and never been run. Was gonna be for a race car and was built as a screamer.

You've got to remember that that Delta Mini is making 210bhp at 9200rpm.

At a guess I'd say that most of the turbo minis on here are making peak bhp at 6 to 7000 rpm.

So what am I saying? errrmm, I think what I'm trying to say is that as BHP is a function of Torque and RPM then 210bhp at a very high rpm is less impressive at the torque will be much lower.
