Initially we sourced the gear sets through Ken Gilanders, but I think the primary source might be Moss Europe. <a href="http://www.moss-europe.co.uk/shop-by-model/triumph/tr5-6/performance-tuning/clutch-gearbox-drivetrain/close-ratio-gear-set.html">http://www.moss-europe.co.uk/shop-by-model/triumph/tr5-6/performance-tuning/clutch-gearbox-drivetrain/close-ratio-gear-set.html</a><div><br></div><div><span style="font-family: Arial, Helvetica, sans-serif; font-size: 11px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 14px; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(247, 247, 246); display: inline !important; float: none; ">1st = 2.19:1, 2nd = 1.57:1, 3rd = 1.23:1, 4th = 1:1</span></div><div><div style="text-align: left;"><font class="Apple-style-span" face="Arial, Helvetica, sans-serif"><span class="Apple-style-span" style="line-height: 14px;"><br></span></font></div><div>I've had no trouble with them whatsoever - though make sure everything is clearanced properly when the box is built! It's great spacing from my perspective.</div><div>I use this box in my GT6 with 13" wheels and a 3.89 rear. Need to slip the clutch around the paddock below 15-20 mph. First gear at 6000 RPM is 47 miles per hour, if I did my math right.</div><div>With a fifteen inch wheel you would pick up another 9%. I don't find there are any tracks except the Pittsburgh Vintage (city streets race) where I am in first gear, as I've got enough grunt in second for the really slow corners. I think if you had a taller first gear or this combined with a taller rear end, you'd have real trouble getting the car moving/clutch issues, particularly if combined with a racing style clutch.</div><div><br><div><div>On May 16, 2016, at 9:07 AM, Greg Blake wrote:</div><br class="Apple-interchange-newline"><div>I know this has been discussed before, but most of the threads I see in the archives are a bit dated. <br>We had our first CVAR event at MSR Houston this past weekend and the need for a usable 2nd and possibly 1st gear were never more noticeable. Since we will no longer be racing at TWS the time has come for me to build a close ratio box. <br>what are our current options to build a close ratio TR6 box. Even though budget does not allow for the dog box option, go ahead and list it so we have a complete listing. I am particularly interested if anyone has an option where 1st is a usable gear as well. <br><br>Thanks. <br><br>Sent from my iPhone<br>_______________________________________________<br><a href="mailto:fot@autox.team.net">fot@autox.team.net</a><br><br>http://www.fot-racing.com<br><br>Donate: http://www.team.net/donate.html<br>Archive: http://www.team.net/archive<br>Forums: http://www.team.net/forums<br>Unsubscribe/Manage: http://autox.team.net/mailman/options/fot/sjanzen@me.com<br><br><br></div></div><br></div></div></body></html>
