Part 3. Getting technical.....
| To hold everything together the engine is secured with a suite of ARP hardware, currently running 1.9 bar sustained boost, without issue. All this extra power means higher oil temperatures, so the simple addition of a PD oil cooler was added along the way. To get this power to the ground, a Sachs Race Engineering organic clutch pack was added, we retained the dual mass flywheel and after two years of use it is in perfect condition. This is driven through the stock ACV gearbox, renowned for its strength. Unfortunately we destroyed two engine blocks with two separate leaking charge coolers, bending a crankshaft, which then shook so hard under load, it shattered two sets of main bearing caps. This kind of thing happens when you’re pushing the limits. This forced an upgrade to a VW engine block from a very early Volvo V70, which is over engineered, stronger yet lighter. For routing back to the turbo, an AXG exhaust manifold was added, as it uses the same footprint as the GT2052V, which links to the 2.5-inch straight through exhaust. |

All this hard work, researching and implementing by MV Engineering was reigned in by Dirty Torque, a custom diesel tuner, they spent the best part of a day taking Bongo Fury through her paces, writing not just a custom map, but also custom sub tables to support it. This resulted in the 221.9bhp and 389.9lb/ft. |
THIRD (and hopefully, final) engine block, kindly supplied by Mule, is from a Volvo.
Who bought their blocks for the engines from VW.
A very yearly block, which was over engineered and should take more power.
