My cheapskate mentality bit me hard at COTA one year, I replaced the external lines, fuel pump, and breather/vent.....It would suck just enough air to let the carb go dry at the end of the straights....

I Had that on my car as well. Its not that its separating, the gas is evaporating away leaving the oil. This is a big carb and the idle is super rich, so there tends to be a little gas/oil that...

Pretty sure SCCA lets you run whatever fuel, as long as its not leaded. Sounds like you are a happy customer from the "Rotary Master"!

I ran different fuel a couple times, I certainly see his...

Never seen this, but I have a guess since nobody else replied...

Perhaps the clip was stretched a little too far on install and then the install of the cluster pushes the shaft against the clip...

Yep, thats exactly what pretty much all cars need to be quick. I ran a little less front caster, about 4.7.

One helpful tip: Move the rear bar softer 1/2" every time out after new tires. Even...

Dmitri,
If its a "spare" engine you need, or if yours is getting older and you need another.... My engine is sitting at Moses' place needing a new home. Super engine, only about 10 races on the...

Engines to be sealed go to Daryl Drummond Engines. If you need a complete engine with all but oil lines and carb, I have mine at Texas Autosports for sale.

All,

Stolen on 1-15-18, a 24' Covered Wagon enclosed trailer. last 5 of the VIN are on the hitch 25353. OK tag # 7P0187

Formula Mazda, Red 08, Black wings, spare nose with white wings. #01-224...

Lots of good info, thanks gents.

I haven't pulled my stuff apart yet. I did go and re-locktite all the bolts. Helped a little.

Way to go brother, that was a great drive!

Maybe, maybe not. Keep in mind, its a straight-cut, dog-ring box, H-pattern. We typically shift without clutch bc its faster so its possible to extend the life by not doing clutchless shifts I...

Wow yall! very good to hear such huge times on a motor.

Sure beats the shifter kart I got out of... "stock" shifter that needs a new piston every weekend and a new piston ring every DAY.

to me, seems like if you are not missing shifts and not junking gears and dog rings you might be fine. Of course, its not much money to add the joint, and its good piece of mind.

Yeah, but I would imagine everyone has about the same cost of fuel cell and (within reason) same cost on wheel bearings

You know, I may have opened a can of worms here.... I bet a lot of classes listed have costs that are not on there, like gearbox maint, clutch, whatever wears out on those classes. They are...

Yeah, the stuff I didn't comment on was pretty close. I have been doing about 4-5 gallons per 30 min session, so 10/hr is about right.
Tires will last 20 heat cycles, but fall off about 7-8 cycles....

Couple of these are tough.... There are no "new" cars.

Typically the complete race ready car is $22,000-25,000
Tires are closer to $1080/set
I would guess that engine competitive hours is...

Hey all,

I was thinking I would replace my weeping oil pan gasket this summer as well as the weeping diff side plates.

Is it easier to pull the engine and gearbox out the top all together? or...

Remember, there is no fan. YES it will climb over 230 just sitting. I did it on grid one time when they neglected to tell us there was a red flag. It will heat until it explodes. ;0)

But yes,...

As far as the smoke....

Get with Moses and get the Oil Metering Pump Block Off Kit. then you switch to using Premix oil like dirtbikes. This will lube the engine better than those crappy...

Yep, what he said. $1100 a set. 3-4 heat cycles is really where they are nice. They don't drop very much, but they do drop every session after 4. Max I have done was about 18 sessions on a set. ...

Yeah, you have to get some rake in the car, or it will understeer like a dumptruck. ;0) get the rear at least 1/2" higher than front. I run 3/4" some run 5/8".

In the carb, your weather is...

Im at work, so forgive me everyone if I get the baseline setup wrong from memory....

Toe: front .150" total, Rear zero
Camber: -.8Front +.2Rear
Caster 4.5 degrees measured on the upright for...

Yep. Best course of action is to go to some races. Don't miss the June sprints at Road America! That will be a big one, and let you see what the larger groups of FM's look like.

Again, Im a bit...

Yep, try Moses at Texas Autosports for test days. He does them, and shares TONS of info. Yes, I have seen 220# guys fit these cars easy. They are actually pretty roomy.

$$$ per fun/speed, I...

I changed over this year, didn't really notice a difference. A little smoke with premix, like it should, but didn't notice anything else.

Don't run it with Lamdas tho. They will mess it up and...

Welcome to your new addiction! =0)

Yes, the SCCA regions and classes are a bit overwhelming when you first look at them.

Hallett OK is the closest track to us. Next would probly be Eagles...

I want to say from memory its the F10 emulsion tube. I don't at all recall the venturi that is used, but we are a 100% stock 13b, 4-port intake with the one piece manifold, stock webber 48DCO/SP. ...

Thank you again Dale, I appreciate it. I started her up the other day when it was 45 degrees out, we were right on with a little bit of idle jet turning to run right. cant get a read on the main...

Guys,

I have been reading a Webber book over the weekend trying to get a handle on knowing how to guess the jetting.... no help. LOL

I think I get the idle jet and screw stuff (thank you...

THat looks like a TON of fun!

Thanks Dale!

If anyone would be so kind....

What is the gearing for Texas world? And Would I probably start with the "standard" suspension setup and tweak on it from there?

Thanks!!!

Darryl, you coming out this year?

Yeah I cant wait for COTA. Racing it in a sports car in Dec. Should be a blast, but in FM will be epic!

I saw the schedule posted in the SOWDIV site, COTA is on! Man Im stoked already!

I still cant tell what all is going on with the Majors regions, hope they map that out shortly. From the...

Oh no!!!! Man that's a bummer.

Hey lemme know what parts you need, I have some extras I can sell you. If you want. No pressure.

I had used Lambdas in a box when I got my car. I am no expert, but to me it seems like they would not be quite right, because of the variable of burning oil in these motors.... So I would actually...

DMitri:

I tried 6mm of toe out, it felt a little twitchy to me, so I went down to about 3-4mm front and zero rear. Feels good to me. You want a little toe out to help turn in and corner...

Yeah, all new bungs, probes. 2" off the header plate. I was reading at the end of the straight at Hallett. I went really rich just to see a baseline. One probe actually died, it only read 400. ...

Dale, you mean 4 MM toe out?

Also, I much apologize for hijacking thread but I have a question... If I'm running a 200 bottom jet in the main stack, and 240 air corrector and seeing 1000...

Yeah, I agree with what was said above.... Least expensive class in SCCA IMO.

I ran in a group with FV, FF, FA at a small race. I was still learning the car but I was 5s/lap off of the FA. ...

the legal one is the 6-port 13B. You could very easily swap the sealed section out with a non-sealed exactly the same and nothing else on the car has to change.... Same intake, exhaust, carb,...

Thx all for the help, I think im going to get a better one later, but for now I made myself a bead seat. I fit well, but its ugly as ****. LOL

Turns out I don't need all that much beading, im...

THX! Yeah just installing the full stack sounds best. then its still ready for another track.

Hey Dale, lookin at your youtube video of the record lap, I would swear that yall are only getting up to 4th gear at hallett. Could I not just put in two first gears so Im using 2-5th? Would that...

THX! Good to know someone here tried them and says its great. That will be my next step. I tried the beaded seat, didn't turn out great, but its ok for now. Going to save up for a better one over...

Its coming together, almost there.

Moses answered me....

This little extra shim goes inside on the shaft to keep from wabbling. Got it figured out now.

Thanks!

Guys,

I got the block off kit from Moses and I am feeling retarded....

I see where the pump thing is, and theres a plate in the kit that looks like it goes there. Can you guys help me...

Thank you Frank!

Hope I can meet ya at a race soon.
