Thanks. I ran these pads for years without big patches of pad transfer. I used to run PFC on a Porsche as well. I feel like something has changed in the past few years. I think I'm going to...

Hi All,
I've used PFC pads on the FM for nearly ten years. I've always been a fan but I feel like the past few years that I have been getting a lot of pad deposition on the rotors which is nearly...

Thanks for that. I was fairly certain it's a stock block.
My car is a bone stock FM and has had a few Drummond motors in it.

I should know this and I can't seem to find it online.

In a standard sealed Drummond 13B, is there any porting or is it a stock block 13B? Is there any other 'work' done on these motors compared...

Regular vinegar or balsamic?

OK, maybe I'm the last guy to figure this out!
The rear bonnet has always been a bit of a pain. Easy to put on with two people but usually requires me to walk back and forth a few times to get the...

Thanks. I emailed Drummond who said this is somewhat normal as well.
Looking at the oil that is on top of my motor, it is fairly clear, so it makes sense that it is separating from the oil/gas mix...

Hi All,
I think I know the answer to this but I want to make sure something isn't wrong.
I recently started using Redline 2-stroke racing oil adding 7.5 oz to 6 gallons of gas per Drummond recs.
I...

Thank you! We did indeed do a decent amount of mixture and jet tuning but I am still really surprised at the speed difference. I'm also about 20 pounds lighter but that doesn't explain these big...

My 13B last year was still making solid power despite having compressions in the 50-60 range. I decided to have Drummond rebuild the motor last winter. It had tremendous scoring in it and he was...

Thanks.

I am going to pre-mix starting next season as there is doubt about the health of my OMP. Darryl Drummond recommends 1 oz racing 2-stroke oil/gallon gas.

Do most of you just add the necessary...

Thanks for the replies guys.
I did some compression tests with a standard tester and the numbers didn't look right. I called Daryl Drummond who told me that using a regular tester isn't going to...

I just looked at their protocol and it suggests 90-120 for peripheral ports. I'll warm it up tomorrow and then check compression.

It's starting OK.
Do you know the normal compression range for our motors? Racing Beat has a protocol for using a standard compression gauge and looking for any differences in oscillations...

My FM has gotten increasingly smokier at idle. It looks like oil smoke.
I checked the spark plugs and they were pretty black.
I changed the plugs and the problem was instantly cured. After a few...

I redrained the coolant and went extra tight on all the fittings. I also found that the clamp on my radiator overflow line had a small leak so that despite plugging the line, it was leaking during...

Thanks.
I think I am going to drain the system again at the left side return pipe and maybe crank the engine for a bit to pump out the residual coolant. Then I'll do another vacuum check for leak...

I changed out the aluminum cooling tubes today because they were getting worn through.

I drained the coolant by simply disconnecting the silicone hoses. I then pulled a vacuum on the system down...

This week I had two fantastic days at Group 52 doing open lapping.
I recorded my best lap ever there of 1:57.52,.....twice!
I am running on the Goodyear 255 simply because I have the most fun on...

OMG Thank you!
It's not easy getting older. Sigh.

Thanks.
I just texted Bruce Lawrence and he thinks Moses has the pipes but they're just not on the site.
I'll post again Monday when I call them.

Hi All,
In the process of identifying a small coolant leak from a loose clamp, it was noticed that the aluminum cooling pipes going to the left pod are partially worn through despite having rubber...

I had Bruce Lawrence make my bead seat when I bought the car from him. It was fairly labor intensive to make. I would recommend having someone make it that has done them before. It fits me...

Rest assured the track records are safe from me! I'm just a trackday hacker having fun with my AWESOME car!

I've been reading about FS and following the logic behind it.

No, my times are on GY 255 or 430 and I was referencing historic track records which I believe are 1:55 at VIR and 1:56 at WGI. I haven't seen any times yet for the 470 at WGI or VIR. I ran the 470...

Thanks for the input.
We put in about a cm of rake and did some more sway bar work and the car is getting better.
Time wise I run low 1:58 at WGI and VIR so about 2 secs off track records.

Thanks Glenn. I am going to experiment with running some rake to see if I can take out some of the understeer.

I know there are a zillion more components to consider, but typically are most people running similar F/R ride heights (around 45mm) or are they running a rake like 45/65 (which I have seen in other...

Thanks guys!

I have decided to have a go at Scca racing with my FM. There is a race at NHMS on Memorial Day weekend. I used to drive that track for many years in PCA. It's bumpy and has abrupt transitions in...

Shane I have only run the 470 once on my FM and I thought it was horrendous. The under steer I got on that compound necessitated ridiculous slowing. Admittedly I just put the tires on without...

I am using an Aim MXL Pista dash. It was installed by Speedsport in CT so I can't give you any tech tips about hooking it up. I use it in conjunction with the AiM Smartycam GP (bullet cam) which is...

I know that with the standard FM muffler that I peak around 101 dB at one sniffing location. Of course there are countless variables in sound measurement so YMMV. When I've run a super...

Thanks again Dan. I appreciate the input.
I'm reasonably experienced with probably 3-400 track days in the past ten years or so although this was my first full year with a formula car.
I...

Thanks Dan.
I didn't realize the 470 was the spec tire for SCCA. My one day experience with it was somewhat negative although as I mentioned the tire looked amazing at the end of the day. At an...

Hi Everyone,
I don't post much but lurk here often.
I'm finishing my first full year of driving a 95 FM that I absolutely love. I bought the car from Bruce Lawrence and have the car cared for by...

This thread looks like a good place for me to introduce myself.

This is my first year driving a FM which I bought from Bruce Lawrence. I'm really enjoying learning the car and have so far driven...
