UTERUS Posted May 14, 2017 Share Posted May 14, 2017 On the subject of HSS twist drills, do split point drills have a place for those of us playing along at home? Or are they for reserved for pros with bigger budgets. Quote Link to comment Share on other sites More sharing options...

Or are they for reserved for pros with bigger budgets. I could be mistaken but I understood split point  to simply be an alternative (and often easier, imo) style of sharpening where you grind in a series of flat spots rather than a single curved face  Dunno if that makes sense Edit. I just Read the article linked above- that's an information overload lol.  Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted May 17, 2017 Share Posted May 17, 2017 Tech question, what pcd are Hondas, Â in particular a Honda rafaga? Quote Link to comment Share on other sites More sharing options...
igor Posted May 17, 2017 Share Posted May 17, 2017 My Civic is the same as four stud Ford/Mazda. Rafaga might logically be expected to be the same. Quote Link to comment Share on other sites More sharing options...

RUNAMUCK Posted May 18, 2017 Share Posted May 18, 2017 Yeah that's what I thought. I have a really ugly set of of mags. They're 114.3 or 110. No better way to get rid of mags than to bolt them to a car and sell it.... Quote Link to comment Share on other sites More sharing options...
kyteler Posted May 18, 2017 Share Posted May 18, 2017 It depended on the car as to the stud pattern. Â 2 Quote Link to comment Share on other sites More sharing options...
Roman Posted May 19, 2017 Author Share Posted May 19, 2017 Today I learn something interesting about caliper placement. The 350Z at work has some big ass Stoptech calipers with some big floating discs on it. Which now causes the problem of pad knockback... When you have a larger diameter disc, when the hub flexes it maginfies how much the outer edge of the disc moves. When you have a 4 pot caliper located on "top" of the disc, (as per 350Z) this means that the disc is being pushed against the pads which pushes the pistons in during hard cornering. A 2 or 1 pot slider caliper is more resilient to this problem because the caliper just moves with the disc. If you put the caliper at the 3 or 9 o clock position instead, with the start of the pad just above or below the centreline of the disc. Then you are much less affected by the hub flexing under cornering and you dont get knockback. (as much) There are kits for the 350Z to relocate the caliper to this position, for this reason. Pad knock back sounds scary as fuck. Coming in hot to a corner then your pedal sinks haha. 8 Quote Link to comment Share on other sites More sharing options...
kicker Posted May 19, 2017 Share Posted May 19, 2017 Interesting You can see a similar thing in motorcycle racing though not very common, a tank slapper can knock the caliper pistons back requiring a couple pumps of the brake to get pressure back but usually by then they have missed their braking marker and it's brown trouser time.

Roman Posted May 19, 2017 Author Share Posted May 19, 2017 One solution is to use springs inserted behind the pistons that pushes them back out. Causes a tiny amount of drag but makes life less scary. Sounds like an absolute bastard to change the pads though haha. Quote Link to comment Share on other sites More sharing options...
HighLUX Posted May 21, 2017 Share Posted May 21, 2017 Â 1GGZE- what triggers the supercharger clutch to lock on. Theres a supercharger relay pin on the ecu. Is that triggering it via tps or similar or does it run off a switch on the accelerator pedal? Quote Link to comment Share on other sites More sharing options...
Spencer Posted May 21, 2017 Share Posted May 21, 2017 It will run off load on the motor? some combo of temp,map/afm, tps, engine speed? can't really remember but ECU control with multiple variables surely. Quote Link to comment Share on other sites More sharing options...
Transom Posted May 22, 2017 Share Posted May 22, 2017 Brake pad knock back Hayes push bike hydro disc brakes were so bad at dragging/sticking pistons the trick was to leave a slight wobble in the disc so it would knock the pads back for less drag/pad glazing /overheating/sticking more in a vicious circle the real fix was take them off and throw away funny I was just reading about the 350z brake issue last night somewhere else Quote Link to comment Share on other sites More sharing options...

Though that must be the case. Il get it running and see if it engages I guess Quote Link to comment Share on other sites More sharing options...

Don't know if you noticed me doing that at Taupo in January when you came for a ride. Also you can get an idea of pedal firmness. Quote Link to comment Share on other sites More sharing options...

Pretty sure it works like a 4A-GZE one, the ECU triggers that relay based on intake manifold vacuum. When vacuum drops below 8" the supercharger clutch is engaged. The clutch stays on until intake manifold vacuum has risen to over 10" for a period of 5 seconds. This time delay was added to avoid cycling of the clutch during shifts and momentary throttle transitions. http://mr2.com/TEXT/SuperChargerInfo.html 5 Quote Link to comment Share on other sites More sharing options...
Seedy Al Posted May 25, 2017 Share Posted May 25, 2017 People were buying tires from sta car parts. I don't think they sell them any more. Â Does anyone have any recommendations on where I can buy some? Â Think my hilux needs a change up. Quote Link to comment Share on other sites More sharing options...
