If you wanted a twin carb Mini with a turbo, wouldn't it need to be a twin turbo? And is there room under the bonnet?

with a 7 port you could have two turbonetics t66's and twin 50 dcoes (bigger is best remember) it wont run but its a show car remember!

Bigger is better

Couldn't disagree more, and the reason why many of these Jap big power 'show cars' are useless for anything competitive.

Whacking the biggest turbo you can find on something does not necessarily make it fast or good to drive.

Errrrrr, you must mean cars like this with turbos like these- which are used for DRAG RACING. Funnily enough they aren't for show, they make things go very fast, like 0-170mph in 7 seconds.

On a road car- not much fun, but why would anyone spend that much money on something hidden in the bonnet if it didn't actually do something. I've seen much bigger turbo's on drag cars than the one in that pic, and seen street legal cars doing the quarter mile in just over 6 seconds thanks to those "show" parts, that are "useless for anything competitive".

Errrrrrm no...actually. By 'show cars' I mean cars in the 'cruising' circles that are described by the inbred owners as high power performance machines. Hence I said 'show cars' and not DRAG RACING CARS. Obviously, if you know what you're doing a big turbo on a big engine with correct set up will launch you in to space. I was talking about a chav with £30k of loan to waste on a Supra, a body kit and a massive single turbo that produces 700bhp but is only useful on dyno runs and for drying your hair.

Type in 'supra show car' to google images and you'll see what I mean. Nowhere did I say anything about DRAG RACING....before you get all the way on to that horse of yours

Hmmm "cruising" i am sure that you have to be a certain "type" for that.

That horse of mine? I was merely pointing out that you said you couldn't disagree more that bigger is better and big turbo's are useless, and I completely disagree.

Firstly, how many chavs have you seen who have £30k to spend on a Supra, and any chavs who do waste money on cars like that do it for looks and sounds.

All the cars with BIG power from BIG turbo's I've ever seen are used for drag runs, RWYB, drifting etc. This includes the SUMO cars which are always presented perfectly and spotless at car shows, yet they drift, race and have an outstanding name for themselves, always with a big turbo.

And 700bhp in a Supra, Skyline etc is good power, and very useable. The engines are designed extraordinarily well and cope with the power, and the sort of person who spends the money to get power like that will 1, use it, 2, had advice on the build to make it useable, and 3, normally know what they are doing. Any idiots who want it wouldn't afford the insurance etc.

I don't know why you're being so aggressive, you claimed that most cars with big turbos are useless and not competitive, which I honestly think is complete BS.

Theres a lot to be said for a 2.8l engine with a turbo that makes over a thousand horse power, especially compared to our and yank engines who in a high state of tune still struggle with 200bhp per litre. I love V8's, but respect Jap engines and Turbo technology no end.

Big engine = big turbo

Littel engine 'A-serise engine for example' = small turbo for acceleration or medium if your going for top speed. But this all comes down to your gearing and pritty much everything else.

Big engine well designed = big turbo for high end + smaller turbo for low down.

Ergh this thread was destined for this outcome... If you'd done a search a few people have asked about twin carb turbo's and i believe from what's been said its not possible (don't take me on that though) and its pointless runing a huge turbo on an A-series...

If your not convinced read up on turbominis

End thread.

[supermotolee]

small engines can run big turbos its about how much air the engine can consume not about physical size i.e motorcycle engines can run big turbos because they rev high and consume alot of air

let him stick a big turbo on there... why not try a holset hx40 or something? bigger is better remember!

[monkey]

Im not gonna pretend to know much about turbos... Ok, so i know nothing about turbos...


BUT, if you have two SMALL turbos (maybe with a carb each??), would they not spool up real quick but produce alot of power? Just a wee thought of mine...

So two cylinders are going to run more boost than the other two then all twin turbo cars go to one plenum even two identical turbos running the same actuators can give different results.

Facts are, one turbo and one carb has proven to give near as dammit 300 bhp, one turbo and one carb works very very well, doing something just to be different rather than a performance end goal will only end one way ............ in tears!

[mini13]

by using two carbs all you are getting is two turds rather than one, and a load of greif getting them set up for no gain.

regarding turbo size you need to look at flow maps, and match them to your engine.

[rick.spi]

with wolfie completly, id take note of what hes saying as he knows what hes on about. it possible but will be as much use as a chocolate teapot, which aint very useful. the A series isnt a big jap engine, youll find all the most of the big powered 5port turbos are running a hif44 and fair sized turboes, ive got a gt20 and thats as big turbo as i would want to go an an a series.

C4NN0N, now go back and read what I actually said without adding your own words in

That horse of mine? I was merely pointing out that you said you couldn't disagree more that bigger is better and big turbo's are useless, and I completely disagree

Did I really say that? No. What I said was:

Whacking the biggest turbo you can find on something does not necessarily make it fast or good to drive.

And that is a comment I stand by and I don't think anyone can argue with. Read again 'does not necessarily'. Not that it doesn't full stop, or for certain applications.

Firstly, how many chavs have you seen who have £30k to spend on a Supra, and any chavs who do waste money on cars like that do it for looks and sounds.

Quite a few I'm afraid. Take a trip to www.barryboys.co.uk, we call them the 'Wallet Barry' which also usually ties in the with the term 'Dyno Queen'. I.e. the chav one way or another has this money to spend, buys a Supra, puts a poorly fitted Veilside kit on it and the biggest turbo he/she can find. This is dyno'd to prove producing 700bhp and that is all the car's used for. 'Car shows' (term used loosely) and a print out to willy wave about power figures is now it's entire purpose in life. Even if the chav does take it on the track or strip, it's fairly useless compared to it's potential and/or power output because the setup isn't tuned properly and it won't spool up until far too late in the rpm range.

Remember, I said

the reason why many of these Jap big power 'show cars' are useless for anything competitive.

Show cars...

All the cars with BIG power from BIG turbo's I've ever seen are used for drag runs, RWYB, drifting etc. This includes the SUMO cars which are always presented perfectly and spotless at car shows, yet they drift, race and have an outstanding name for themselves, always with a big turbo.

Great, well done! Biscuit?
Purpose built cars with properly and fully set up engines along with everything else, tuned by people that know what they're doing. Not what I'm talking about, and I'm pretty sure if you described these cars to the owners/teams faces as 'show cars', they wouldn't be too happy.

Again, I'm talking about a Knackered Supra with a massive turbo, weighty lumps of fiberglass glued to it and 20" tasteless alloys.

And 700bhp in a Supra, Skyline etc is good power, and very useable. The engines are designed extraordinarily well and cope with the power, and the sort of person who spends the money to get power like that will 1, use it, 2, had advice on the build to make it useable, and 3, normally know what they are doing. Any idiots who want it wouldn't afford the insurance etc.

Is it? All of them? Have you driven all of them?
You're wrong, partly. It can be. It can be very usable and nice to drive but it does all depend on how it's set up. I know the engines can cope with the power, didn't say anything against the engines, I'm a massive Skyline fan myself but; the person who spends the money to get power like that in the chav world will 1, not use it for anything other than shows and willy waving because it is not usable power, 2 have had poor (being kind) advice or will have completely ignored it all, and 3, not have the foggiest what they are really doing with their lives, because they are building a dyno queen show car.

You seem to be going on about purposefully built and/or modified cars by teams, companies and owners that know what they're doing. That's a completely different ball game to the idiots of society. And again, yes they actually do exist and own too much money.

I don't know why you're being so aggressive, you claimed that most cars with big turbos are useless and not competitive, which I honestly think is complete BS.

Again, you've not correctly read anything I've actually said. I did not say most cars, I said:

many of these Jap big power 'show cars'

I also said:

Whacking the biggest turbo you can find on something does not necessarily make it fast or good to drive.

which I honestly think is true. Quite where I said 'most cars with big turbos are useless and not competitive' is a mystery to me. Although I can see where you would have got that from if you were so enraged by the anti-jap car comments that you simply couldn't wait to write a scathing reply and as such didn't bother reading anything properly. Take a step back and breathe. I'm not anti-jap car at all, they're phenomenal machines in the right hands, just as crap as anything else in the wrong hands though.

Theres a lot to be said for a 2.8l engine with a turbo that makes over a thousand horse power, especially compared to our and yank engines who in a high state of tune still struggle with 200bhp per litre. I love V8's, but respect Jap engines and Turbo technology no end.

First good point you have made. I'm sure you know what you are talking about, sounds it, but you've been trying to put me down for comments that I haven't actually made. You've got completely the wrong end of my twin turbo stick. I completely agree with you on this one though, I love v8's just as much as I love Jap turbos and vice versa. Both have their advantages and disadvantages, and both in the right hands can be made to spin the world around. In fact both are my favourite types of engine above anything else, I don't really have much love for other things. Not saying they're useless before you or someone else starts again, but for reasons they're my favourites.

Hope you can now see where I'm coming from?...

[red_mini_MMM]

do it id love to see the power outputs

[TopCatCustom]

I can't be bothered with stupid sarcastic replies, why can't you argue without pathetic comments like "biscuit?" And "first good point you have made".
I'm not anti-jap, pro-jap or anything, its not rocket science to see that you can't just bolt a big turbo onto something and get perfect results, but I didn't know that people actually did that in your "barry boy" world. I was merely disagreeing with your original post which implied that you thought that big turbos suck and cars with them are uncompetitive, which I think was fair enough to assume by your text.
I'm not associated with "show only car" owners and all the cars I know with big power and turbos are used for racing of some kind, normally drag racing, for which lag doesn't matter when the drive ratios, torque converter lock up, revs etc are worked out.

Anyway- to the OP, sorry for going off topic, I think what I should have implied is that you can do whatever you want, if the maths are done and it is set up correctly, which with some engines like the A series is going to be hard with big FI. There's a bel air or something out there with 8 turbos, one per cylinder so anything can be done, with the right amount of money.
