Pop along if you have the time.... would be good especially if you are good with a camera
#304: Re: Macs rally 206 project.. New engine spec Author: macj, Location: EssexPosted: Fri Aug 26, 2011 10:25 am ---- The new engine is finally finished with a few alterations to the original plan.
1. Gas flowed head with 5 angle valve seats, uprated valve springs and welded up EGR port.
2 Port matched manifold with modifications to fit the 45mm T/B`s and improve air velocity.
3. Forged "H" section steel conrods and HC forged Wossner 12.5:1CR pistons.
4.Polished crankshaft and lightened flywheel all fully balanced.
5. Heavy duty race spec bearings.
6. Uprated oil pump.
The engine was dummy built to check the CR and it sits nicely at 12.2:1. The whole engine is now just over a full rally spec and the head has been opened up considerably with full knife edging in the ports. and Charlie from CTM Performance Engineering who has done all the work thinks it will be a monster engine.
As for the power figures, he has made a prediction...... but I cant tell you what that is or it will spoil the surprise when it comes off the rollers
You still have time to get your quesses in before the RR session
#305: Re: Macs rally 206 project.. New engine spec Author: Seabook, Posted: Fri Aug 26, 2011 10:33 am ---- i am optimistic as always; still think it can hit at least 210bhp; if not 220.

The new figure for the rev limiter has been raised from 7200rpm to 7800rpm soft limiter and 8000 hard limiter..... thats scary stuff

Can you give any detail or brand for that? And is your pistons 2 ring ?
And my guess about RR. If you still in standart cams i think 205 hp with a good cam you will see 225 hp

The end shells are made by Mahle but ACL are the same quality
The pistons are 3 ring
The oil pump has an uprated relief spring fitted which is available through CTM Performance Engineering

#313: Re: Macs rally 206 project.. New engine spec & Pictures Author: Abzynthe, Posted: Sat Aug 27, 2011 8:36 am ---- really tastey looking
#314: Re: Macs rally 206 project.. New engine spec & Pictures Author: macj, Location: EssexPosted: Sat Aug 27, 2011 8:40 am ---- The attention to detail is what makes all the other "would be" tuners look like ameteurs. He has even changed the manifold to T/B studs as he felt they were not long enough.
#315: Re: Macs rally 206 project.. New engine spec & Pictures Author: Edward, Location: In the garagePosted: Sat Aug 27, 2011 11:58 am ---- Has the block been painted? I always wonder if shot blasting an engine prior to strip down would finish it off like new.
Even the bottom pulley looks nice. Bolts look new too. I want a new pulley as there is a bit of corrosion on mine. £55 for a new one...
Is your rear rocker cover breather connected to anything? I see the later EW engines with the tall rocker covers have a breather on the inlet cam cover too. Any rally or touring car EW engine seem to have a breather on the front cover. Do you think having one would be an advantage?
