I just cut back the wiring and heat shrink in the car wiring and there’s a blue and a black wire. I determined the blue wire is hot with 12.9 volts, so the black is the ground. Easy enough.
...

How will I know which is the hot lead on the rainlight?

Does it matter which wire goes to which wire? I’ve got a 50/50 chance of getting it right, which means I’ll smoke my new rainlight lol. Both wires on the car are colored white. I haven’t...

Awesome thanks. I found a kit on Amazon that has both sides of the plug already assembled. I’ll just have to solder and heat shrink the wires.

Here’s a couple pics if that helps. I need to know what the other half of this is. These pics are from the rainlight pigtail.
...

Could you look for me please and let me know. It would be super helpful to know. Was that on Jeff’s car?

I just got done installing the new FIA rainlight on the new rear wing brackets and someone’s changed the electrical connector on the car.

Anyone got any ideas to get a matching connector to...

Okay thanks for all your advise guys.

That’s a good point, thank you.

I’m thinking about moving the auxiliary battery connection from the rear wing mount to the left side engine case, just in front of the left rear tire. I’ve seen it mounted there on several cars....

If they don’t have any, I have a full set of wheels, with old rains on them that I’ll never use. I don’t want to split up the set of 4, but I’ll give you a great price on the full set. They...

Thanks again Dave, I found it on page 51 of that manual. It makes sense now.

Thanks Dave. Am I correct that I don’t want that notched flange to come out of the side of the gearbox?

Is there a spiral retaining ring on the wheel/tire end of the axel too?

Thanks for all your responses guys, they’ve been a big help.

Okay thank you, I really appreciate your help.

Hi Fred, okay thank you.

Should I replace or clean the magnet that’s in the bottom of the case? It’s got some fuzz on it. Do I have to remove the lower stack of gears to get to the magnet?...

Okay I wanted to thank everyone for their help.

I had a great track day at Willow Springs today. It was 46* when I got there and had both radiators halfway blocked off with aluminum plates. ...

Is anyone using it for their Hewland FTR?

The off-road racing community uses it a lot. There’s nothing more abused than an off-road racing gearbox.

I haven’t seen anyone here talking...

Have you checked Starracecars.com ? They have most everything for PFM’s.

No I don’t have a cooling fan. Maris gave me his before he moved back to Europe, but I haven’t installed it yet. I’ll have to look at that more closely.

I hate idling in the staging area...

Okay thx!

Yes thx. I just ordered a leaf blower for my buddy in the paddock to blow into the water radiator, until the oil temps come up.

I just looked at my car. It has the thermostat housing on it. I...

I just looked at that thermostat housing on Starracecars.com and it’s a water thermostat housing.

Yes, limp mode is what’s been happening. The last track day I had 1/3 of the oil and water radiators blocked off. This time it will be 1/2 of both of them, and a roll of duct tape nearby. Thanks...

I wasn’t aware that there is a thermostat available for a PFM. I’ll look up that part number.

If you know, is that thermostat for the water or oil? I can’t keep the temperature up high...

Hi Dave, thank you.

We’ve got some friends that retired and moved to Paso. They live in a community about 1/2 hour out of town, near a small shopping center that has a gas station, pizza...

Thanks Mikey. So blocking off 50% or more of the radiators is acceptable to get the operating temps correct?

Sorry for the dumb questions, I’ve never had a car without a thermostat.

I’ve got a Track Day at Willow Springs scheduled for the 20th. I made up some 1/8” aluminum plates to block off part of the oil and water radiators. On the past Track Days I blocked off about...

Ok thanks!

Ok thanks!

To drain the gearbox, I remove the rear cover, correct? Is there a gasket that will need replacing after I pull the cover off?

That’s a good idea, I’ll have to make up something like that. I had a hard time getting the tape measure down in the fill hole 7”. I thought it might catch on something coming out and snap...

Ok thanks, I saw that. It’s eerily similar to checking the engine oil. I thought they had their wires crossed.

Thanks for your response.

I have a small spin on type oil filter on top of a pedestal on top of the engine, but it sounds like I’ve done everything right so far.

Where did you get the Hewland...

This is the first time changing the engine oil and gearbox oil. I’ve read the Star Race Cars manual but it’s confusing.

I suctioned out 4 quarts of engine oil from the pedestal with the two...

Okay, thank you.

Is the gearbox drain plug above the little tray you’re talking about?

I got my PFM on the lift and can’t see one. Do only the carbon fiber ones have the trans
service port? Or did I get bad info?

March 20 is the next Track Day at Willow Springs. I plan on going with my PFM. If you’re around Robb, meet me there if you want.

I almost forgot.


Look at Davefreitasracing.com. He’s in Whittier. Maris took me to his shop a few years ago. Nice and clean small shop with several different types of cars that he was...

I’m 6’00 and 190 lbs and I fit in my PFM with room to spare. I have to take my tennis shoes off to get my feet on the pedals. With racing shoes it’s fine.

I bought a PFM three years ago as my first formula car. The learning curve was steep but several peeps on this Forum helped me a lot. Maris and I became friends and we went to Willow Springs a...

Do a Google search on Moses Smith Formula Mazda. I just did and there’s all his info. He’s in Mexico now at the Baja 1000.

Hey Maris good to hear you’re doing well. No more plumbing huh? Race cars are way more fun than plumbing. Post the videos when you get a chance and say HI to your family for us.

There’s a paint shop next to Van Nuys Airport if you want it go that far. The owner is a friend of my wife’s and they do excellent work. Let me know if you want his contact info.

The suction cup mount is very strong. It stayed in place all day on my off-road car windshield.

Mine is a 2009 so it’s the latest. It doesn’t have that horizontal piece. I thought the only difference was aluminum vs carbon fiber construction. Maybe someone else will chime in that knows...

They came with the car when I bought it used. They were the spare set of sticker tires that were mounted on wheels.

I just looked, they are 210’s on the front.
