Someone being amazed by Flex sensor readings. Just ignore his nonsense ramblings about the sensor measuring gasoline content
at him being surprised by the water thing

Beware with the Flex fuel sensors, because (just like the O2 sensors don't really measure air/fuel ratio) these don't really measure ethanol content!! Inside the sensor it is pretty much two electrodes dipped into the fuel (which form a capacitor) and it measures the capacitance. It has a preset for...

~15 years ago the CSM/CST rules were - if you could drive from Cal speedway to the McDonald's on Foothill and Cherry without getting arrested, you're ok for the class. I don't know who added the California registration eligibility thing since, but it totally doesn't fit the spirit of that class beca...

From your video -> the third cone of the first slalom at 0:57

Here is onboard from my Miata. 65.9 Visually the course was quite challenging and while walking I thought some sections would be quite a pain to go through. Then it was time to drive and I was pleasantly surprised that it flowed really well. I liked it a lot. A great course (by a first time designe...

"Vehicles eligible for CSM must be capable of being licensed for street use in California" When was this added to the rules???! Few years ago when we had lots of fun in that class the rule was - "you have to be able to drive the car to the closest McDonalds without getting arrested&q...

Actually 24hr Lemans and other 24hr type races are actually bad examples to show your point. Fastest Raw speed does NOT sit atop the podium. Most completed laps does, often it's not by the fastest car or even class on the track, but the one who spent the least time making repairs and other off trac...

There is no "serious race series" as you called it where a grid would include: a F1, Top Fuel Dragster, NASCAR, and a 450 MX bike waiting for a green flag, and expecting some form of parity between them. Since I mentioned LeMans and WRC ... their grids are quite mixed if you look at the s...

Haha. Quite true
LeMans, WRC, etc. no serious race series including multiple classes use silly multipliers... Overall winner is always the fastest raw time

Mako, you want this http://cms.kraftwerksusa.com/id/930/KraftWerks-98-05-Mazda-Miata-Supercharger-Kits/" onclick="window.open(this.href);return false; I drove Williams, along with several other peoples. Power of a turbo, but response of the supercharger. That for autocross would be a tota...

There are some very nice, albeit not cheap, super charging kits out there ... to take your NA to the next level. :D If he is afraid of NB Miatas "invading" ES, he would be running screaming away from SSM (where supercharged Miata go). SSM is a $$$$$$ class (if building a competetive car) ...

Ignoring the suspension geometry advantage of SLA cars and the mechanical grip of a 200TW street vs an A6 for a moment... Can anyone propose a reasonable method to gain static camber on an SLA car? the SLA equivalent of camber plates are replacement adjustable upper control arms. Yep, or (as was po...

About the dampers, the funny thing is that some manufacturers use remote reservoirs because it is cheaper/easier designing it that way.
Ban the reservoirs so people start buying uber expensive dampers which fit everything in the same housing?

Seems the 500 Abarths don't need rear brakes either ...

This is from Andy Hollis on BFG and Z2: Back from Daytona...sorry for the delay. Working on getting tires to test for GRM, but dates are fluid. At the launch event, I was the lucky dog. I was there a day early for some on-camera interviews, and while watching the BFG lead test driver gathering on-tr...

(wow Rosenthal Mazda ships fast!), Btw, for racers Mazdaspeed Motorsports is faster and cheaper than generic Mazda dealers like Rosenthal (Mazda dealers buy the parts at the same price you would buy directly from Mazda and then resell to you for profit) The regional Mazda warehouse is in Ontario so...

Since there is no posted date yet, please do not do it on MLK long weekend (Jan 19-21). With nothing on the calendar for MLK I guess most people have scheduled the upcoming long weekend already.

The Toyota museum in Torrance was a great place for the party Can we still go there?

Supposedly Subaru said there is no room for a front mounted IC ... thus no plans for Turbo'ing. I don't believe that's the entire truth. Maybe no turboing this year, but if you look at the exhaust routing - the pipes from the driver side manifold go across the front of the engine to the passenger s...

If I read this correctly, I see that the front to rear weight distribution is about 56%/44%. If BMW's can get close to 50/50 with a long 6-cylinder inline, why is it that Subaru/Toyota can achieve only 56/44 given the short boxer engine, which was supposedly pushed as far back as possible?! You mea...

the cheating part is putting toms data overlaid on his video and then going frame by frame comparing to to my data/video overlay. :heyes:

Based on Sunday's results, it works quite well though.

if it was not working well it wouldn't be cheating ...
