When I rebuilt my engine I went with the 87.5 big bore (why they make an 87, and 87.5 I don't know) a TR4A head, skinny fan belt with billet pulleys and harmonic balancer pulley and alternator, wizard aluminum radiator with electric fan, along with the 9.2 lb flywheel, so with that many mods it's not easy determine the single most difference, but it does "scoot". I think John Linney's the best testimonial because I believe that was the single thing he did at the time, so he can actually compare the before and after of the lightened flywheel.</div><div><br></div><div class="x-apple-signature">Rye<br>PH: 530-FIND-RYE</div><div><br>On April 11, 2020 at 4:53 AM, andrew uprichard <auprichard@uprichard.net> wrote:<br><br></div><div><blockquote type="cite"><div class="msg-quote"><div class="_stretch"><span class="body-text-content">Both my keeper TR3s have lightened wheels and I notice a distinct difference<br>between them and the other TR3s I have had, but my keepers also have 89mm<br>pistons and the other cars have usually had 87mm. <br><br>I did not lighten the flywheels, however, I bought them from a manufacturer.<br><br>|Andrew Uprichard<br>Jackson, MI<br><br>-----Original Message-----<br>From: Triumphs <triumphs-bounces@autox.team.net> On Behalf Of bill beecher<br>Sent: Friday, April 10, 2020 9:44 PM<br>To: Dave Ranteer <triumphs@autox.team.net><br>Subject: [TR] Lightening a TR flywheel<br><br>What is the general opinion of lightening the TR3 flywheel for use on the<br>street?
