afx Posted January 27, 2015 Author Share Posted January 27, 2015 (edited) Weird engine, did Ford develope this just for racing? It is a production engine that Ford used in the Escort. Cosworth was involved in developing the engine for racing. They eventually coaxed 272 bhp out of this little beast. Originally conceived by Mike Hall (Cosworth Engineering) as a belt driven version of Cosworth’s FVA power plant, this engine is based on the Ford 1600 X/Flow bottom end. It made its first appearance in the Mk1 Escort in 1970 and replaced the Lotus twin cam engine as the new high performance engine for the Ford Rally Sport models. During the early seventies Brian Hart (amongst many others) developed this engine further and his 87mm big bore alloy block version, giving an increased capacity to 1840cc, was eventually adopted by Ford and used to power the later RS1800 Escort. The BDA and all its derivatives went on to dominate the motorsport scene and even today, 30 years on, it is still providing many winning cars with their power. At least 15 types have been produced ranging from the 1098cc BDJ (150bhp) through to the 2 litre BDTE turbo version (650bhp in full race trim) which was produced with a slightly longer block to improve its structural strength.

afx Posted January 27, 2015 Author Share Posted January 27, 2015 Thanx for the info JC. I see what you mean now. The head is dang near as tall as the block! I wouldn't mind having a similar engine for my little Escort build. It's in stall mode at the moment. This engine or a Twin Cam would look cool in your Escort build Roger. The only source of the BDA that I am aware of is the Esci/Revell Escort kits. The Twin Cam is available in a few kits and at one time a resin cast version was available from Mini Exotics if I remember correctly. Pretty sure Mini Exotics is out of business.

afx Posted January 27, 2015 Author Share Posted January 27, 2015 Great work JC, I think the engine looks real good so far. About that header I think you got it as close as you could without making an entire engine from scratch. Thanks Robert. I have more scratch building to do for the engine so I didn't want to add to that with a custom header. Just plain outstanding scratch building skills. Thanks Jim.

afx Posted January 30, 2015 Author Share Posted January 30, 2015 (edited) Hi JC, Beautiful work as always !!!!! Is your motor going to have some sidedraft webers ? Randy Yes sir. A pair of side draft Webers. I'm working on the throttle linkage right now. Edited January 30, 2015 by afx Quote Link to comment Share on other sites More sharing options...
Speedfreak Posted January 30, 2015 Share Posted January 30, 2015 Yes! Bring on the sidedraft Webers! Quote Link to comment Share on other sites More sharing options...
afx Posted January 31, 2015 Author Share Posted January 31, 2015 (edited) Fabricated carburetor linkage. The linkage attaches the cylinder head like on the 1:1. Therefore I need to wait until everything is permanently installed to complete the rest of the linkage.

afx Posted January 31, 2015 Author Share Posted January 31, 2015 (edited) If my updates are too trivial please let me know. I'm sure it looks like very little has been accomplished sometimes but when you're making most of the parts the progress feels more significant.

Speedfreak Posted January 31, 2015 Share Posted January 31, 2015 (edited) Good work JC, Everything but the obvious plastic parts looks like a real engine, those brass pieces add to that as well. What did you paint the block with JC? Edit: It's not too trivial Edited January 31, 2015 by Speedfreak Quote Link to comment Share on other sites More sharing options...

Speedfreak Posted January 31, 2015 Share Posted January 31, 2015 Wow, at least from that last pic, you could just put a wash on it, ('cause it kind of looks like a block with a little grime/age on it) but , I'm sure it looks different 1:1.

fitforbattle Posted February 1, 2015 Share Posted February 1, 2015 (edited) Might just be the pictures, but compared to the reference picture the bottom pulley appears to sit too high. Look how the belt wraps around the bottom right pulley before going back. Maybe it's just a mirage. Great updates as always. Your builds are great. Edit: Might actually be the lower right pulley sitting too low? Edited February 1, 2015 by fitforbattle Quote Link to comment Share on other sites More sharing options...

If that doesn't work then I'll use masking tape cut into a thin strip. Quote Link to comment Share on other sites More sharing options...
