just curious

[ejoeyward]

im looking at building an m10 turbo looking
i see loads of people have done this on injectors but has any1 done this with blow through carbs or is it just not worth the hassle

[broadie]

If your right into your carbs and gonna set it up yourself go for the carbs. If your paying someone else to set up its got to be injection.

thanks for that link
iv done blow through carbs with a friend on a 1275gt mini with a supercharger also got another friend who works for eaton he's a got 1.1 a series mini, i dont know how it works but his carbs are before the supercharger although i think this would be highly dangerous with how hot a turbo runs thats even if it is possible.

[Speedtouch]

I would have thought that a turbo on a 1098cc A-series would be a waste of time - it's a long-stroke engine that doesn't really like to be revved beyond about 5,000rpm, and won't take beyond 6,000rpm for long before the crank snaps!

[pacerpete]

Don't bother, it will cost a fortune, be no faster than a 325 and break ,regularly.


Countdown until some M10 freak comes along and tells us that a turboed M10 just like the one in his sahara beige 316 auto was fitted to F1 cars and made twelfty million horsepower at the spare wheel (5j) 3. 2. 1.........

[broadie]

I see the troll has arived!
The mini might be a bored out 1000.

A draw through turbo has different seals try the mister turbo site or aerodine. On a draw through you don't need to pressurize the float chamber, quite often used on bikes.

....after having had the block peed upon by Bavarian lederhosen wearers to stiffen it up to immeasurable levels of stiffness.

It is better to fit carb before supercharcher as petrol helps create a better seal between vanes ( depending on type) and takes heat away from a charge thus increasing efficiency of supercharger

Could be a 1071 'S' engine. I broke the crank on a 1098 once and it still ran surprisingly well. Good enough for me to drive it home!

sorry i may have been unclear the 1.1 is supercharged not turbo
i was thinking maybe its possible to put carbs before a turbo on a m10 maybe it would be easier than a blow through setup

btw i dont care about how much power it would produce and how much it would cost i just want to be different thats why my original idea was to supercharge a m44b19 stroked to a 2.1 but i cant be bothered with the wiring so i just want an engine that pretty much plug and play and then i cant do abit of work here and there

[Speedtouch]

It can be done:

[ejoeyward]

OMG!!!! i love it and i want to do it might need some help from you guys though like what carbs would be best, i mean a big 4 barrel holley might be a bit much for a little old m10. i am a big fan of any engine with twin 45 webers

[Speedtouch]

Webers do lend themselves quite well to turbocharging, but I'd imagine you could face alot of tuning issues trying to get a pair to work properly with a turbo setup.

You could just use the one specially-designed Dellorto, such as used on the Lotus Esprit turbo:

[ejoeyward]

yeah id totally forgot the lotus turbo was running carbs thanks next question is what manifold would work i was thinking i could maybe adapt the top half of a m40 intake manifold minus the throttle body or if my memory serves me right my friend is running Dellorto 45's on one of his mini's with a superflow aluminium manifold which can be brought brand new for 60 quid. BARGAIN!!!! if it would work

[Brianmoooore]

we're half way through the second decade of the 21st century. Why would anyone outside of historic racing series and museum exhibitors be contemplating using this primitive and poorly performing 19th century invention?

[Speedtouch]

SU HIF44 FTW! I have had one on my 1275cc A-series for years now (mostly driven daily, in all weathers) and it still performs well, and returns respectable fuel economy.

Nowt wrong with decent carbs, if set up right.

[ejoeyward]

i just wanna be different i dont care about the numbers really ok iv got a number in my head but im not gunna be pist if i dont get there the most important thing is when someone opens the bonnet and you just get a smile from them

[Speedtouch]

Yeah, why not. If it worked on the Formula 1 cars and 2002 Turbo, I don't see why a home-brew effort couldn't be built to give a reasonable enhancement in performance, even if it is carb-based.

[ejoeyward]

andits not like im just gunna leave the head and block alone im thinking of omega pistons and stroking it but what cranks will fit? i know the s14 fits but thats a bit far out of my budget i have a knife edged m44 crank and a e46 320d crank

im gunna find a decent fast road cam and port polish down to the finest little detail and a really hot coil and do as much as i can to cool the engine/bay so oil cooler and loads of ceramic raps

[pacerpete]

What happened to 'budget' and 'cheap' ?

[ejoeyward]

What happened to 'budget' and 'cheap' ?

to start of with it will be cheap and cheerful but once start i wont be able to stop which im sure alot of you guys are the same just have a one of a kind car

not all the work will be done in one go the first aim is to get it in and running. The engine im sure will be pulled and stripped multiple times just to do a bit of work.

what do you think this would be like with a 6 speed diesel gearbox bolted to it and what diff would you use

Thing is all the new fuel injected bikes can't achieve the economy of a lot older carbed bikes. Tech ain't all its cracked up to be.

i am a big fan of any engine with twin 45 webers

45 weber's have poor progression, Dellorto's would be a better choice.

[ejoeyward]

im now thinking about a 2 barrel edelbrock as i can find a manifold for it where it is difficult for twin 45's or 40's
it will still be about the same cfm. webs and delortos 45's are roughly between 315 and 330 cfm each

and we all know edelbrocks respond well to forced induction, just got to look at the supercharged v8's

next is the turbo which im thinking of either one from a impreza sti (gt30) or an audi s3 (kf04) but i do have a eaton m45 supercharger just siting in my shed

[bdx]

yawn....

[Speedtouch]

Eaton supercharger sounds like the way to go...

[ejoeyward]

my dad will be pist cuz he was gunna put it on his audi
