Passion 4
Well-known member
Is anybody interested in a rather special (already proven & well known) BWA 2.4 type 4 motor? Could be a first if it was used in a USB as well?
Best of the best by Ahnendorp BAS (http://www.ahnendorp.com), turnkey, Porsche Cooling, twin 44 webbers, special stainless BAS 4 into 1 merged header, it has separate risers to prevent the head studs pulling under warm up (like a Porsche) it’s has a totally merged system with springed collector, all stainless etc. sounds great, plus lots of goodies, just had a full strip down, clean & reassemble so now all ready to go again.
Although it ran a 15.4 without trying too hard, it really isnt an out and out drag motor, more a superb smooth torque monster on the street and motorways
Only raced officially 6 runs (Not by me ), then street use… mileage approx 10,000 not enough to carbon up the piston tops, if thats any indication?
No problem, the exact original specs from BAS were a bit vague, but it was built as a money no object item (cost over £10k!)… hence the way it performs!
I’ll just double check the exact specs with Rob at RNJ Motorsport, as he has quite literally, just completed a full strip down, clean and re-assemble, plus fitted some new goodies and tweaked the heads to give a better compression ratio, so he knows far better than me what it has got in it, but from memory it has;
• Genuine 103 mm mahle barrels and pistons
• Match ported manifolds
• Extensively reworked heads
• 3 Angle Valve job
• Clearanced case, lightened and balanced
• Heads have a 58cc chamber
• Compression ratio set at 8.9-1
• Schleicher 324° Cam with special grind
• Powerband from 3,500 to 7,500 rpm
• Twin weber 44 carbs/linkage
• BAS thermo oil block/external oil temp bypass
• K&N filters
• Genuine Porsche cooling; 11 blade fan with built in regulator
• Balanced rods/crank/lightened flywheel
• All lightened /balanced/blueprinted and match weighted
• 8mm stainless valves
• Re-worked 2 litre Porsche crank, nitride, balanced
• New barrel shims
• New pushrod tubes
• New chromoly retainers
• New dual valve springs
• New DIS-IX Ignition System for 009 distributor
Bit of an old cliché, but as I’m sure you are aware, you could not build it for this kind of money!
Bargain at £6k
Happy to personally deliver anywhere in mainland UK at 50p/mile round trip
Now I’ll let the pics do the talking…
for those that asked, here are a few pics I took today…
