escondidoron in correct, Hydraulics can are counter intuitive. It all about areas not diameter's. If you have a master cylinder that has a 1 Square Inch piston and you apply 100 pounds pressure to the pedal your hydraulic system is pressurized to 100psi. So if the area of the caliper pistons pressing on the pads is 2 Square Inch you have 200 pounds pressure at the pads. If you put in a larger master cylinder lets say 2 Square Inch but you still have the same 100 pounds pressure on the pedal you now only have 50psi in your system, with the same 2 square inch caliper pistons you only have 100psi at the pads. You have just halved your braking pressure. But your pedal will feel a lot firmer as it will take 1/2 the pedal travel to move the pads the same amount. Graham

I tried to take a picture on my Locost but it's up on jack stands so the suspension is in droop. But here is a picture you can see the upward slope of the top a-arm. A better place to ask your question is the Locost forum, lots of very knowledgeable people on suspension design, check out http://locostusa.com/forums/ http://www.mglocost.com/images/big/lfcorner.jpg

If you have the a-arms parallel the wheel move directly up and down, the camber will remain the same, that is very bad, because as the chassis rolls in the turns you will get increasing positive camber, not good. So you want the upper control arm lower by the chassis, that will increase the negative camber as the wheel moves up. That will increase in the positive camber that will be offset by the chassis rolling. So if the angles are correct you will still have negative camber throughout the corner. Graham

The new track focused Birkin Tom was driving at NJMP 2020 was a stunning looking car. Inboard shock and a very neat inboard anti roll bar setup. I loved the one piece hood that went right up to the dash so all the elecrickery was easy to work on. Graham

Check out the 2017 NJMP event we had a beautiful Mallock on the track

He has Mallock for sale, very cool. Graham

There is a simple test, use a volt meter and measure your battery voltage with the car not running. Start the car let it warm up and settle to a steady idle, measure the battery village again with the engine running. If voltage running is less than voltage not running your alternator is not putting out enough current at issue speed. My tiny alternator has that problem, but I don't spend extended time at idle. Graham

Good luck. Thanks for all your effort. Graham

I refitted a panel directly behind the nose cone on my Locost. It has been laying around in the garage for years I had just not got around to putting it back on. The car went from running very cool to instant overheating, about 4 laps at VIR and I was at critical temps. There is a lot of air coming thru the nosecone it has to go somewhere. I tried to upload a picture, but it did not work. Graham

I have done a couple of there events when I lived in Chicago. Well run, great routes and a great group of guys. Alas 1000 miles away from my current location. Graham

Engineering Explained is one of the leading educational channels on YouTube with 2.5 million subscriber, you should review his channel he explains some cool automotive stuff. He based his numbers on the preposterous MPGE number. The auto industry found the real MPGE number so revolting they lobbied HARD to get the number fuzzed, the original MPGE number was about 275 MPGE it was revised by politicians down to about 100 MPGE. Then you have the advances in technology like digital batteries. I could have a car with a 3000 mile range you could drive across the USA without recharging https://www.forbes.com/sites/quickerbettertech/2020/12/13/battery-breakthroughsand-other-small-business-tech-news/?sh=18a35b433700. Electric cars are coming get over it. Graham

The extra demand on the electric grid it not as high as you would think, only Graham

Imagine how expensive a Caterham would be if it contained many custom parts? Using of the shelf parts dramatically reduces cost. Graham

I was looking for another event, this will be perfect late season event. Looking for a new tow vehicle, the Cherokee is just not up to long distance towing, and it looks like Bowling Green, Mid Ohio, VIR, Pitrace, NJMP and now CMP are on the years schedule. Graham

I had a Escort Twin Cam, the successor to the Lotus Cortina. White, big wing, AVO plate. Great car. Have always wanted another one. A friend in the UK still has his original RS1600 BDA car. Graham

Carl, you right about the R53, I have driven all the later Cooper S models, they are faster but just don't have the agile direct steering of the R53. This one is actually my second I had one when they first came out but sold it when I went to work for Toyota. I was looking for a fun go to work car and did not expect to buy another R53, I found a one owner 04 with 75K, always genuine BMW dealer maintained with just a stack of paperwork for 5K. I love the car. My tow vehicle is a 97 Cherokee XJ, 179K miles runs and drives perfectly. But 20 years living in Chicago is bad on the steel it's just exploding with rust, so I am starting to look for it's replacement. The wife drives a 19 GTI so that's another fun car in the house. Graham

Still getting the Vbulletin version in MD. Graham

R53 Mini Cooper S, this is my second on the new BMW Minis. But my 5th Mini overall. Love the R53 so much fun. Graham

The AC does sap power but not as much as you would think probably 10-15hp. But the AC does not know how powerful the engine is, so it would drain the same amount of power on a Honda Civic as a Dodge Redeye. But it would pay huge dividends when you already have 700bhp. I don't think you can use the setup on a race/trackday car, the system would just heat soak quickly, but on a daily driver it would be prefect. Graham

Play with this Dyno correction factor calculator and you can see, it's not as much as you think. Some say 1% hp per 10 degrees. https://wahiduddin.net/calc/calc_cf.htm Graham

I just noticed that some organization are still allowing the SA2010 helmet for this year. From the Autointerest site "I certify that I have a SA2010 or newer rated helmet (SA ONLY!)" Just looked and MVP Tracktime is doing the same.

Helmets are all about fit, some brands just fit you noggin more comfortably. I am using a Bell M3 (no longer made) but it's expiring, so I a looking for a new one. I will probably just go with the M8 just because there is a good chance of it fitting well. I tend not to go for the high end brands were a large percentage of the money goes to high end sponsored drivers/riders. They all pass the same standard, it's a pass/fail test so I am not sure more money gets you more safety. So go with the most comfortable fit. Graham

I stumbled across this video on YouTube and remembered this post. I little talkative but a lot of information. Move those injectors:) Graham

We went to Rabbit Hash Kentucky once, very cute little town, Ginger got into a fight with the mayor, I thought she was going to end up in jail. Graham

I used M3 with a nice button head allen bolt on my Locost scuttle. But I also had problems with the rounding as there is so little tool engagement. So I swapped to SS Phillips button heads. Much better and I can remove them with a power tools in seconds. From McMaster Carr you get 100 for $5. https://www.mcmaster.com/screws/rounded-head-screws/phillips-rounded-head-screws/metric-18-8-stainless-steel-pan-head-phillips-screws/ Graham
