  1. "The thinnest adapters they offer are 19mm thick, you have to factor that into the equation for the new wheel offset. I chose the 19mm adapters which puts the total offset at 43mm or 44mm depending upon which source you use for the original offset. I have seen both 24mm and 25mm listed. I ended up going to 16x7 wheels with a 4x100 bolt pattern and 42mm offset. Using 205/45R16 tires and on the 16x7 wheels............." Hi, read the above on: http://tr7triumph.com/forum/viewtopic.php?t=13458 Should the offset now be 5mm or 6mm? not 43mm or 44mm? This is of course assuming we are talking positive offset/ET.

    Offset question?

    Hi Alan, It's Unfortunate we disagree. The original post was made in my search of KPI/SAI & castor information & some conflicting information. Cheers, Iain.

    Offset question?

    Hi Alan, I disagree that you can not change the ET of a wheel. Machine the hub mounting surface of the wheel and you will increase the ET of that wheel when fitted. Add a spacer and you will reduce the ET of the wheel when fitted. That's appears to be a fact? .Cheers, Iain. PS. 122344, Thanks for the extra info.

    Offset question?

    Hi Alan, Offset and ET are not the same thing? I understand that ET and backspacing are not the same but mathematically related. Cheers, Iain.

    Offset question?

    Hi Alan, Just checked the link & is correct. He was saying that a spacer or adaptor in this case increases ET. It does not. It reduces it. The new offset is 5mm or 6mm not 43mm or 44mm. I spent hours last night checking and checking. Loads of wrong advice out there. Back space and ET are related. I will stick with the German metric ET. Whats an inch? LOL. http://www.gtsparkplugs.com/Offset-to-Backspace.html Cheers, Iain.

    idle control valve

    Hi, two pin solenoids are not. i'm not aware of a diode being built into the solenoid which would make it polarity sensitive. Cheers, Iain.

    GT6 Mkii OEM wheel ET

    Hi appears there are at least 3 different wheel offsets for spits and GT6's. Source: different quoted KPI settings. Cheers, Iain.
  8. Hi, I just found an interesting topic on here about wheels. The last post in May 2018 asked about OEM wheel ET. This was after trying for two hours to search for "Spitfire wheel offset mm " to no avail. Can't even find a post from me telling me.. So, I'm here with my new topic. What is the wheel offset of the OEM wheels fitted to the GT6 Mkii? The same question for MGF wheels. (Range of ET). I want to eliminate any possible changes to the centre line of my fitted tyres relative to OEM. I want to get the suspension realigned with me in the car this time with wishbones set parallel to the ground. My front tyres are 175mm across but stiffer than the 175/70/13's. I appear to have the same non-contact issues, so my 15" on front and 16" on rear ET is very similar? Cheers, Iain. PS. HAPPY NEWYEAR just for you JD!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    Those crazy Russians

    You where driving from Port of Spain? When I was there, I got run off the road by two very big guys with guns. Saw I was white and lowered the guns instead of shooting. LOL. Happy days. Cheers, Iain.

    Those crazy Russians

    LOL. Car might be built in Russia but the design is not. Lada/VAZ are crap. They are cheap to repair because the parts are made of junk. You change the mechanics all the time, but no problem as the crap replacements are very cheap. Thirty years later your Lada is a bit like "Triggers brush". Not having to MOT the car every year helps in keeping it on the road for a very long time. Cheers, Iain. PS. The video was worth the watch. Seen the same guy before with DIY wood brake pads and other crazy stuff/mods.

    idle control valve

    Hi, I have at least four ICV's. 2 wire, 3 wire & stepper motor types. If you need/require TSO, the 3 wire is the one to use. From my limited experience in blowing a 2 wire and a 3 wire; The 3 wire was Tight Shut Off & when commanded to full open, flowed more than the two wire. The 2 wire is easy to DIY control if a minimum flow rate is acceptable. The 3 wire is easier to control than the precision stepper motor types. I have no idea if the stepper motor types can achieve TSO. Cheers, Iain.

    GT6 Mkii OEM wheel ET

    Hi, I have 39" of track at the front +/- 10mm. need to accurately measure. lol The driver's side appears to be closer to the wing. Imagination, just an illusion? (Band from the 80's) MGF wheels appear to span from 28 to 35mm ET. on Int'net. For appearance, I could increase the rear tyre width by at least 10mm as there is space. Adding a 6mm spacer will move them out and increase rear track without increasing tyre width beyond recommend tyre width on the 7J's. My wheel ET will only improve? Cheers, Iain.

    EWP Controller

    Hi, I was impressed with the 80L/s flow rate but no where near that fitted to an engine. lol. The EWP shouldn't be stalling the engine under full load as its only around 80 Watts? I think my present stat has too many holes, takes forever to warm up. Cheers, Iain PS. On my car, there is/was always coolant flow with a closed OEM stat as I have a fitted heater for warmth & temperature measurement. I have not had a fitted heater control valve for over 20 years. No hot air and I'm low on coolant and overheating; gauge would probably say OK as no coolant. LOL. I do have a gauge to fit and will do.

    EWP Controller

    Hi Richy_Rich, I recollect that with the EWP a thermostat was not required. I know a restriction was required to the flow out of the head and that a thermostat with its gut removed didn't restrict the flow enough at high RPM. load. Warmup was much improved with a stat + controller +EWP. Warmup + heat capacity was maximum with the pump at 14.7 Volts from alternator AND a three port thermostat. Removing the need for the water pump/stat housing makes the 3 port housing relatively simple. Win,Win. The OEM stat will just try to control temperature exiting the head. The three port will regulate according to rad DeltaT; If the dynamic cooling ability of the rad changes, the stat will modulate quicker. Cheers, Iain.

    GT6 Mkii OEM wheel ET

    Hi, If I measure my track & track is same as the book for Mkii GT6 then ET/Offset must be same as OEM? If my track is smaller then spacers will correct this? I think any spacer less than 14mm is acceptable as the previous 6J's on rear were fitted with 13mm spacers. I removed the 1/2" spacers when I increased the wheel width to 7". Seemed to make sense at the time.. Cheers, Iain.

    GT6 Mkii OEM wheel ET

    Cheers, I think the MGF wheels are greater than this. So wheel spacers will fix this if I'm correct. Iain.

    EWP Controller

    Here is a picture of the large plastic pump controller graph contradicting my erroneous memory. Hi, If it was done without semiconductors; A suitably preset thermostat sat low in the coolant to short-out a suitable power resistor that is used to drop 8 volts would give the two speeds. In the end, I ran the 2000 Hrs rated pump at system voltage from an alternator switched relay powered by the ignition. I said the minimum voltage was 7 volts & that not to rely on convection alone at ambient and below temperatures. The EWP data sheet says differently. Sorry. A restriction out off head is needed to prevent boiling, more so with the EWP flow being less at high RPM. I used a coin with a few holes to obtain this in place of OEM stat and fitted a three port modern thermostat. It looked kak with all the hoses. One of the many problems was that the many many hose connections were all under stress. Crap install from my end was the one problem despite the money thrown at it. My expansion tank is too small to allow the 5% expansion of the coolant being the main problem. I was going to control the EWP from my ECU via a power FET with PWM. I purchased loads of interface chips & IRF's to simply achieve this but lost interest and went back to stock. Cooling fine now if a little bit too cool @ motorway speeds. I suspect I have drilled too many holes in the OEM stat, or that the stat is not really 88c as marked. The small buck-boost single IC PCB's would work for a lower preheat speed as the current is a fraction of the 7? Amps required a full RPM. Cheers, Iain

    EWP Controller

    Hi, If you want to control the EWP RPM, I would give it a minimum voltage of around 7 volts and pulse it to adjust RPM. When warming engine up I would not rely on convection. I did look at PID control before I realised that I had wasted loads of money and that the crap mech pump is less trouble. Cheers, Iain.

    EWP Controller

    Hi, I always thought the EWP was a very good idea. 1. The EWP has a more efficient pump design. The OEM Triumph impeller looks very inefficient. (of course, the EWP flow was never enough to turn the mech pump if left fitted) 2. The EWP has more flow at idle speeds. (Now, I have no idea). 3. The EWP can run with engine off to cool or preheat the engine if suitable oil or water heaters are fitted. 4. The controller (Old analogue type they no longer sell) Pulses with a variable duty cycle of around 7 volts until around 60c is reached and then it becomes PWM up to the adjusted setpoint. 5. Faster warm-up time….. I installed my 1st EWP & analogue controller in 2000. Spliced into the bottom hose. OEM pump installed with no drive. Thermostat installed. A fan was controlled by a relay in parallel with pump- fan only came on when pump running above 90c The heater was kak so bought and installed booster pump fed from the ignition. Bought a new EWP in 2004 after pump #1 stopped rotating. EWP #2 fitted with water pump blanking plate. A tee into the EWP was provided to give a heater return path. Not too many breakdowns & heater was OK. 2014, EWP#2 starts leaking. Car unusable. Prior to this, the sensor mounted at the same level as temperature sender failed. The pump was wired to constant ignition feed. EWP#3 New and bigger alloy EWP ordered. New shapes and sizes of silicone hose orders. Three port modern 32mm 88c thermostat ordered. Suitable ROC thermistor was ordered to resurrect the analogue EWP controller. 2nd hand water pump purchased and machined with flat thermostat plate and 32mm hose barb in the bottom. Oww. Three port thermostat fitted so coolant flow was modulated thru the radiator. Heater crap again System OK unless the coolant gets a little low-- China syndrome. 14th December 2017. I have the AA report. The drive home from work was interrupted when the unique water pump housing fell to bits. A place called dick lane. Sat in a damp & wet car with no internet for 5 hours. The two “sisters” in the house that I could see into from my dark vantage spot progressed out of eye-shot. 10;30 got home pissed offski. Mech pump fitted. 88c thermostat and too much cooling at high RPM. Happy days. Do not fit an EWP without a restriction from the head. Thermostat or two-pound coin with a hole drilled thru works fine. Cheers, Iain. PS. I do have the 190? Alloy pump somewhere and will sell it.

    Hi, I would be picking a Piper cam over a Newman one. I don't have any sources as this is my own opinion. Quality. Cheers, Iain.

    Crankcase Breather Mod

    Hi, I have a PCV. My choice was the one that had the hose barbs. Could not find one with two 1/2" barbs, so one is 10mm OD. It's the lower absolute pressure side. I do need to control the fresh air into the engine though? Hence the orifice. Cheers, Iain.

    Crankcase Breather Mod

    Hi, Would love to see a higher res photo if possible? I see Nick utilises a 3mm orifice. I have a couple of flow control valves somewhere. Have to find a way to connect one between the air filter and the rocker box. I hope that taking filtered air in at the top and out at the bottom (Mech fuel-pump location)? One of the flow control valves, ICV. Two pin type. Going to bung some voltage up it to see if it can seal! Cheers, Iain.

    Crankcase Breather Mod

    Hi, I could not see a wiper motor? It's a shame it's not an easy job to rotate the thermostat housing 90 degrees CCW. Would save you around 200g of hose clamps. I will need to put a restrictor on rocker box inlet set to allow maximum flow that does not affect idle speed, yet needs to flow more at high RPM. Waiting for an ICV to arrive. 2 & 3 pin. The idle control thread is 9/16" UNF? Cheers, Iain. EDIT: My eyes are bad. I think I see the end of it now.
