BDA Engine...

[MexDan]

Routing through the garage the other day and i found a 711m block serial number 711m6015aa..

 

So obviously its a 1100/1300 block.. but can these be bored out to 1600s?

 

Also i read somewhere the 711m block can be used as a base for a BDA/BDG engine..

 

Is this true or am i talking out of my arse??

 

Cheers

 

[tim]

no cus the 1600 block is an inch taller than the 1100/1300 block

[MexDan]

ok mate... cheers..

 

Ebay here it comes!!! lol

 

Would it be possible with a 1600 block then??

 

Cheers

 

[tim]

the first bda were based on 711 bottom ends,

 

it would be possible with the 1100/1300 block aswell,it just wouldnt be a bda,it would be a bdh if it was a 1300

[MexDan]

Ah i see..

 

So what engine block did the 1800s and 2l BD engines run then???

 

Also there are some huge variations in the power described these engines can create.. would 270bhp sound about right for a 2litre version??? I know that is what the works cars used to produce..

 

Cheers

 

[tim]

most ran BDG 2ltr alloy blocks,1975cc and 275bhp

 

but the bdh 1300 engine produced 190 for gp2 sport cars right up to the BDT that the rs200 rans.

if you search on turbosport for BDA then there loads of info on the different CC and BHP they had

 

but the first BDA that was in road RS1600 was 1601 with 120bhp

[MexDan]

OK Cheers Tim.. Thanks for your help!!

 

I had a chat to a guy just up the road from me at brands hatch- HT engineering... and we were talking bout the possibility (and price ) of a BDA (240bhp) and it works out about the same as the cosworth lump i wanted ..

 

And there is no better sound than a BDA on full chat

I had a 1600 XF iron blocked B.D.A. rebuilt for the new owner of my old mk1 RS1600 i had 14 years ago and it was very very expensive . You would be better off with something else unless very rich

If you mean HT Racing they come highly recommended

[MexDan]

Yeah it was HT Racing

 

To be honest I have a x/flow in the escort atm which is almost tweaked flat out.. and the car is undergoing som major surgery during next winter and i think that will be the time it gets it new heart.

 

The BD series is legendary, and although its more expensive, I would love to keep to the classic rally stuff... not taking anything away from cossie powered OSF because they are the nuts... its just a personal preferance

 

Seeing as the car is to be done as a works spec car... then i might as well go the whole hog

Well it wont detract from the value!! I recon every sane person would give their eye teeth for a BD!!

 

For the record how much HP does the "on the limit" CF put out? And on who's rollers?

[MexDan]

Engine is a Vulcan 1700 putting out 150bhp when last tested, I cant remember which rollers it was but i have the sheets somewhere!!

 

Dont get me wrong its a good engine... loads of acceleration as it been setup for rallying. Lightened flywheel so its not that good for dragging but once your rolling its on fire!!

 

But if i'm gonna buy a new engine.. I'm gonna buy a beast...

it would be possible with the 1100/1300 block aswell,it just wouldnt be a bda,it would be a bdh if it was a 1300

First BDAs were not built on the 711m but on the L block, and the BDA was built as a 1.3, Formula 4 engine I think, and possibly Atlantic Junior

I think the 1,8 BDAs were bored 1,6 X flows and the 2,0 were Hart blocks, with a long stroke crank

[tim]

there isnt nothing quit like the sound of BD on full chat but can be pricey,stayin period what about a lotus twin cam for an AX tall block xflow

[Anglia68]

I've still got the BDA out of my Anglia van which I am slowly rebuilding.I don't have a lot of money so that's why I'm doing it myself over several years.

Two years ago I bought a big valve head,last year I bought steel rods and 83.5mm forged pistons and hopefully this year I'll be getting a steel crank.

Sadly to do this I've had to put my AX block on e-bay.

Blatent self promotion I know.

 

A Zetec would be cheaper and just as powerful,probably a lot more reliable but when you have a dream what can you do?

My dream is a BDA engined Anglia on bike carbs with nitrous.

 

[MexDan]

So what difference does it make putting bike carbs on it???

 

I had looked at Twin Cams as another option but from what i've read they are no where near as powerful as a BD engine??

 

cheers!!

 

[Toby]

Ain't no substitute for valves I mean cubes!! Or both!!

 

I think a REALLY good twink gets around 170 genuine horses from 1600cc which is mega, but an 8V just can't breath enough to spin fast enough to make really big horses!!

 

How much is a BD from HT then?

[Anglia68]

So what difference does it make putting bike carbs on it???

 

Probably not a lot but I just fancy trying it as the inlet ports on the head are at an angle facing upwards so the bike carbs can be mounted on straight pipes like the old fashioned fuel injection was.

It'll take me till 2010 to build it though so I may change my mind.

[MexDan]

Its a fair few mate..

 

From what i've heard they start at around 12k.. which is a huge amount of benjamin

 

But I almost bought a Cossie engine the other day and by the time I had finished doing adding all the bits I wanted for it up it gets to that sort of dough anyway, so thought I would see what peoples opinions were on it before I took the plunge on the cossie

 

Whilst a cossie is much cheaper to buy to start, by the time its finished

[Toby]

And it's still not a BD when it is finished!!
