The FWA became popular in sportscar racing and was followed by the Mark II and then by the FWB, which had a capacity of nearly 1.5-litres. The new <a href="/wiki/Formula_Two" title="Formula Two">Formula Two</a> regulations suited the 1.5-litre engine, and it quickly became the engine to have in F2 racing. By 1957, the first Climax engines began to appear in <a href="/wiki/Formula_One" title="Formula One">Formula One</a> in the back of Cooper chassis. </p><p>Initially, these were FWBs, but the FPF engine followed. Stirling Moss scored the company's first Formula One victory in Argentina in 1958, using a 2-litre version of the engine. In general terms, however, the engines were not powerful enough to compete with the 2.5-litre machinery, and it was not until the 2.5-litre version of the FPF arrived in 1959 that <a href="/wiki/Jack_Brabham" title="Jack Brabham">Jack Brabham</a> was able to win the world championship in a Cooper-Climax.

This resulted in the development of SOHC 654 cc (2.35" bore x 2.25" stroke) FWM in 1957, which basically was a smaller and lighter version of FWP with many detailed differences that reflect the improvements and cost-cutting as well as weight-saving measures found in the development of FWA, FWB, and FWE. The differences include: </p> <ul><li>Deletion of the intermediary shaft (Jackshaft) making the cam drive a single stage chain as opposed to FW series' two stage gear/chain set up. This made the camshaft turn in the same direction as the crank.</li> <li>Conrod big end part line was made horizontal, as opposed to the previous diagonal.</li> <li>The number of cylinder head studs was reduced from 18 to 10.<sup id="cite_ref-26" class="reference"><a href="#cite_note-26"><span class="cite-bracket">[</span>25<span class="cite-bracket">]</span></a></sup></li></ul> <div class="mw-heading mw-heading4"><h4 id="_Evolution"> Evolution</h4><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Coventry_Climax&action=edit&section=18" title="Edit section: Evolution"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>FWM was then developed into an automotive engine as FWMA of 742 cc with larger 2.45" bore and 2.4" stroke in 1959.

With this problem solved in the Mk.II 186 bhp version, having a larger 1.35" intake valves (1.30" previously), FWMV started to score GP victories, ending the 1962 season with 3 wins for Lotus, 1 win for Cooper, 5 second places and 4 third places, in addition to 7 pole positions and 6 fastest laps. </p><p>For 1963, Coventry Climax was able to convince <a href="/wiki/Lucas_Industries" title="Lucas Industries">Lucas</a> to supply the cogged belt-driven fuel injection system originally developed for <a href="/wiki/British_Racing_Motors" title="British Racing Motors">BRM</a> with then-unique sliding throttle plates with four round intake bores cut out. With the larger bore (from 63 mm to 68 mm) and shorter stroke (60 mm to 51.5 mm) compared to Mk.II, notable changes include the increase in conrod length (from 4.2" to 5.1" centre to centre, with a shorter piston crown height) and the switch from <a href="/wiki/V8_engine#Design" title="V8 engine">crossplane</a> to <a href="/wiki/Flat-plane_crank" title="Flat-plane crank">flat-plane crankshaft</a>, which surprisingly did not increase vibration in the higher RPM range because the longer conrod length counteracted the increase in <a href="/wiki/Engine_balance#Secondary_balance" title="Engine balance">secondary vibration</a> inherent in flatplane design. </p><p>The flat-plane crank was adopted partly due to <a href="/wiki/Rob_Walker_Racing_Team" title="Rob Walker Racing Team">Rob Walker</a>'s proposed successor to the 4WD <a href="/wiki/Ferguson_P99" title="Ferguson P99">Ferguson P99</a> Formula 1 having a front engine layout, which could not accommodate exhaust pipes that merge with pipes from exhaust ports on the opposing banks on <a href="/wiki/Crossplane#90°_V8_crankshaft" title="Crossplane">crossplane</a> arrangement, but this project did not materialise.

One-off Mk.5 was made with a larger inlet valve (from 1.35" to 1.40") for 203 bhp (151 kW), which was delivered to Lotus and said to be used by Clark in the 1964 season. Mk.4 and Mk.5 scored five wins (three by Clark for Lotus, two by Gurney for Brabham), seven pole positions, and seven fastest laps. </p><p>A one-off 4 valve Mk.6 had 1.04" intake and 0.935" exhaust valves, new pistons, cylinder sleeves and crankshaft, and had gear driven camshafts as opposed to the previous chain drive. This engine made 212 bhp (158 kW) at 10300rpm and went to Lotus during 1965. Another 4 valve one-off, Mk.7, was built with 1.107" intake and 1.043" exhaust and all the new Mk.6 parts for 213 bhp (159 kW) at 10500rpm, and was delivered to Brabham.

This was because Coventry Climax had started the FWMW flat-16 project, which was finally announced at the beginning of 1965, and had more than a handful in things needed to be developed or solved, so the 4 valve configuration on FWMV did not get completely developed nor did reach a series production. However, Jim Clark was able to win 6 championship races (3 with Mk.6), 6 pole positions and 6 fastest laps to become the 1965 World Champion. </p><p>At the end of the 1965 season, the failure of FWMW project left Coventry Climax with no 3 litre successor to FWMV for the next season, so a 2 Litre version of FWMV was assembled using Mk.4 bore (72.40 mm) and Mk.II stroke (60.00 mm) and was used by Lotus in 1966 as a stopgap until 3 litre BRM H-16 engines became available but with little success.

Design work started in 1963, and a prototype was running on the bench in late 1964 with two flatplane flat-8 cranks end-to-end, shrunk-fit to a central spur gear at 90 degrees phase shift to each other<sup id="cite_ref-29" class="reference"><a href="#cite_note-29"><span class="cite-bracket">[</span>a<span class="cite-bracket">]</span></a></sup>. </p><p>Work on this project continued through the later years of the 1.5 Litre formula with Lotus and Brabham the likely recipients. The engine was fairly compact at 30.9" long (only 1" longer than FWMV Mk.4) and 22.6" wide, but there were a number of design issues still to solve before the formula ran out. Not only had the engine shown no power advantage over the V8 despite its much higher rev limit, but it had mechanical problems that would have required either a major rework to solve properly or, at the least, the need for complete engine rebuilds after 3 hours of running. </p><p>From the outset, the largest problem was <a href="/wiki/Torsional_vibration" title="Torsional vibration">torsional vibration</a> of the crankshaft, which at one time necessitated a ban on using less than 4000 rpm on the bench. The vibration often caused one or other of the cranks to shear itself off the central spur gear, resulting in the engine becoming two aphasic flat-8s, or the parallel <a href="/wiki/Quill_shaft" class="mw-redirect" title="Quill shaft">quill shaft</a> (driven at 0.8 times the crank speed, located below crank, and in turn driving the flywheel and ancillaries) overheated and disintegrated. </p><p>The central power-take-off system using the parallel shaft was intended to reduce torsional vibration of the long crankshaft, but destructive vibration appeared no matter what was changed in firing order, crank counter-weight configuration or crankshaft weight distribution. </p><p>As a result, Coventry Climax could not derive revenues from the project, and was further forced to develop a 2-Litre version of FWMV so that Lotus, who built one <a href="/wiki/Lotus_33" title="Lotus 33">Lotus 33</a> chassis specifically for FWMW, and were counting on using FWMW's anticipated 3-litre successor, could avoid missing the first races of the 1966 season. Neither the old four-cylinder FPF nor the eight-cylinder FWMV could be enlarged to 3 litres, and the 11 years old 2.5-Litre FPE parts had been sold off in their entirety and were in the hands of <a href="/wiki/Paul_Emery" title="Paul Emery">Paul Emery</a>, who was in the process of enlarging FPE to 3-Litres. </p><p>Partly because of this project's grand scale failure, and partly because of Jaguar's take over<sup id="cite_ref-30" class="reference"><a href="#cite_note-30"><span class="cite-bracket">[</span>b<span class="cite-bracket">]</span></a></sup> in 1963, Coventry Climax could not develop a 3-litre successor to the FWMW, and announced its withdrawal from the F1 engine business.
