Hi John, You have a Personal Message. Mick Richards

Hi Chris, That's strange, the standard section 165 80 15 tyres on 5.5 wheels are the optimum mix on the TR for handling, as in change of direction and cornering inputs. The 195 tyres do give more grip for point and squirt (marginally more tyre on the road, there's about 15% of the tyre on the outside barely touches the tarmac because of the negative camber) maybe that's what you mean ? Mick Richards

Michael, There's a saying, "if your car feels like it's on tracks...you ain't driving it fast enough". NO car drives around a track and doesn't exhibit ...behaviours,... understeer, oversteer, roll understeer, roll oversteer, drifting, weaving under braking, snap oversteer from understeer when power input is varied (famous on a Porsche). That's why when you set a cars handling up first you make it safe, ...then you make it nasty, having a car that WON'T change direction in a snap or it's attitude (car placement or axis on the track) makes for a car that's slower to drive, and less s

Hi John, Nice to see you on the forum again, hope Lynn and yourself are ok. Mick Richards

+1 for the stub stacks, not as impressive looking as 3" ram pipes but about 50% more effective. Mick Richards

Peter Burgess at Automotive Performance Engineering in Alfreton 01773 520021 has had some Mikuni's go through his rolling road (probably on MGBs) and he rates them. Mick Richards

Stuart from the Watermill Carriage Company has Dellorto 40s on his car, but I can't remember whether 86 or 89mm pistons, so he may be able to give a starting point. Mick Richards

Never heard of a Nikuni ? is that a typo of Mikuni ? Mick Richards

Again...Nope, the reason the Porsche uses CN36 (or other high grip tyres) is because the chassis design produces high rear axle grip from the weight the rear engine placement directly over the rear axle gives it, and along with it's great grip, a high polar moment of inertia...ie once a side force is input into the chassis and the rear end starts to move sidewards, if you panic and reduce the power substantially the rear end whips back across in the opposite direction. If a manufacturer makes it "standard equipment on a Porsche" (well back in the 90s anyway) there's a reason It's a g

Oh the improvements are there, it's just they require the car be improved by application of "suites" of parts and work. Reworked head, bigger valves, performance camshaft, better injection system or using Weber carbs, and then internal engineering work to utilise these parts. You can't add an exhaust = 3hp, add a head = 10 hp et etc, the law of incremental advantageous improvements comes about. By altering one item it gives an advantage which is multiplied by the next alteration better than by addition, ie a 3hp performance exhaust gain when multiplied by another complimentary addition of

Andy, There is no "silver bullet" for performance parts, especially on the TR 4 cylinder engine but applies pretty equally to most cars. If a manufacturer could gain 10 or 15 hp (about 10% on Triumph engines) just by the substitution of 1 part at reasonable cost...they would. Mick Richards

Like the windscreen glass seal, go and do something else for 4 or 5 days in case the seal creeps back towards the centre, less likely because of the positive fittings but that's what I did. Mick Richards

Nope… try CN 36, standard equipment on a Porsche. Sticks like poo to a blanket even in the wet. Mick Richards

Depends if you've done anything else to the standard set up of a TR6. The standard 165 80 15 tyres present a full width but rounder profile to the road surface when loaded, with a more compliant carcass against the 195 and allowing the tyre to "roll" it's footprint as it was designed to, you'll find low speed manoeuvring, parking etc much lighter on the arms wrists and hands, as against the "needing muscles in your spit" forces that apply with 195 section tyres. The 195 even though a wider tyre, because of camber inputs from the suspension front and rear doesn't hardly touch the road on

Hi Rich, what paint are you using on the casing itself, looks smart. Mick Richards

I like your luggage Marco, bet your darling wife has it full whilst yours is in a soft bag in the boot lol. Mick Richards

I've not got a TR6 but is the circled bracket an anti "shunt" bracket to stop the steering rack displacing backwards and the steering column spearing the drivers chest...unless I dreamt it. Mick Richards

Just a point Peter, if it's a Police vehicle that comes behind you and indicates you are to proceed through a red light you make a note of his reg number and the date and time of the incident. If a summons from a Traffic light camera is issued you'll need them to prove why you transgressed a red light. A Police officer is allowed to make a judgemental call on road conditions and if it's safe to allow or instruct traffic to go through lights at red, after all it's what they do when they direct traffic when they take over at junctions, if traffic lights are U/S for example. If it's Fire brigade

"Couple into this the work to secure and move the Classic Mini tooling, jigs and fixtures before some get rich quick merchant sold it all from Birmingham for scrap. " Hi Pete, I'm unclear, does the above sentance mean the jigs and fixtures were protected ok ? or does it mean it was unsuccessful and some "get rich quick merchant sold it all from Birmingham for scrap." and it's all now been reconstituted intp picnic trays ? .Heritage has form on this sort of vandalism Mick Richards Edited 1 hour ago by BlueTR3A-5EKT

Found my i Phone in the Carp pond (don't put them in your shirt top pocket) with my endescope, luckily knew where it went in and 5 minutes searching in a grid pattern found it. No ill effects on the endescope. Mick Richards

Rob, just for clarification the "rev counter" is called a Tachometer, a Tachograph is a recording device similar to speedometer in a car but fitted to vans over 3.5 tons and trucks and transcribes the vehicles speeds and times of being driven onto a paper disc or other recording function so the authorities can check and control trucks and their firms and drivers and prevent them speeding, exceeding drivers hours and several other misdemeanours they get up to. I'd suggest leaving the thread title now unless a moderator can alter it. Mick Richards

John, I don't believe we are trying to put people off or scaremonger about the dangers that exist, and it is precisely because "it is a bit of fun" that it can be dangerous. When competitors are taking it seriously and adopting all possible safety measures that's when you can quantify the risk, when people are "driving fast" but not competitively and the unforeseen happens that is when everybody wishes that safety had been considered to it's maximum. I consider how I used to prepare myself when experiencing my introduction to Motorsport via sprinting and " big bucks " were not to be sp
