All 3 on the trans. And I sure hope not on the rear end....but you never know.

Interesting on the 4 speed. If it is never going to get driven on the street again it'll be pretty easy, in theory.

It's a race car. It only get's driven on the street to and from a few local car meets from time to time. I can gear 4th however I want....but I think I will keep it 1:1 just in case I ever want to sale it.

I want to know how you can get 4th anything besides 1:1, as far as I can tell, in this style 4 speed, 4th gear means the input shaft is directly connected to the output shaft and no gears are transmitting power. But when I look at the numbers again, 1:1 with a 3.63 rear is only ~4200 rpm @80 thats about what the 1.6 miata is. So its not as bad as I thought it was.

After reading more about the Jericho's they sound awesome... too bad they cost an arm and a leg.

You can always get a very similar box from a guy on BaT that rebuilds retired nascar boxes to whatever ratios you want for like 2500+shipping. It wont say jerico on it, it wont be as light, but it should last longer than 500 miles like I hear the jericos do.

Are you talking a Brinn, Falcon or Bert 2speed trans? Or another 4 speed racing designed trans? Jericho is the only NASCAR manufactuer that I know of that's not based around a richmond or muncie case and gearset. Which now that I really think about it, is probably just fine for us.

Just as a note, the Brinn/Bert/Falcon transmissions look good for us, right up until you realize that they work in a wildly different fashion, and would probably be a bear to launch.

Its just listed as a T101a based tranny. The guts and externals look like the same design as the jerico 4 speed, just like the GForce units. Though I guess there's only a few ways to do a side loader 4 speed.

Whoa whoa whoa

Them some fighting words...

I think Auto X and W2W racing are so wildly different it's almost impossible to say one is "harder" than the other. They are difficult in very different ways, in my experience.

I can promise you, W2W racing at the Grand AM level is not easy, by any stretch of the imagination.

Anyways, apples to oranges

Where in my post did I say W2W racing was easy? I gave my EDUCATED opinion and backed it up with personal experience.

I will however concede that my Auto X experience is at the pinnacle of the sport racing against the best cars and best drivers in the country....my W2W experience was not at that level.

Last event before Nationals. Leaving on Thursday night. Hope to see some of you there.



And I REALLY should get the title of this thread changed to something else.....but this is just where most of my posts have ended up.

So in getting ready for Nationals I found a oil leak at the oil cooler sandwich plate. So I fixed that oil leak...then decided I would lay under the car with the motor running to check and see if I had fixed the oil leak. Well I heard a noise I wasn't crazy about so I began to trouble shoot the issue. It sounds like a HLA but on the bottom side of the motor. I have done every trick in the book to try and isolate the noise. Stethoscope, removing accessory drive belts. having someone push the clutch in, disconnected each coil wire one at a time, changed the oil, searched for metal, cut the filter open and searched for metal, took the valve cover off and turned the motor over to verify that oil was getting to the top end, did a compression test, measured valve clearances, checked the plugs......and I'm sure a few other things I can't remember at this point. And I am not any closer today to telling you want the noise is than I was when I started. I have ruled out the PS pump, the alternator and the blower.....it could pretty much be anything else. I was surprised that even with a stethoscope I wasn't able to pinpoint the source of the noise.

It seems to be present only at idle (or is covered up by other noises when you are above idle), can really only be heard if you are laying under the car with the car running(with under car acoustics it's REALLY hard to tell where the noise is coming from) with the stethoscope I couldn't pinpoint where the noise was originating

I'm supposed to leave to head to the Pro Solo Finale in the morning but I'm not leaving until I have a better idea of where this noise is coming from. Good news is if I can't find the source of the noise I have have a good friend who is going to let me drive his multi time National Championship winning E-Stock car.....but I REALLY want to be in SSM

My fear is you are hearing a bearing noise, like rod knock?

hrk

iTrader: (6)

No signs of bearing material in oilfilter or in used oil? Rod knock can be heard on idle first, under load the gaps are closed tight.
Other motor where I had the tick, it turned out to be cracked piston. Worked ok even on a trackday. No issues on compression either.
Not the guesses you want to hear I am sure.

Well that's obviously the biggest fear....but it doesn't have the "trademark" characteristics of a rod knock. Nor does it have them of a main knock. That is what is so odd.

On of my friends is convinced it is an exhaust leak because it is hard to pinpoint and isn't really standing out with the stethoscope

At this point I am not as worried about what it is....I just want to find out WHAT it is....(I had already planned on putting new rings and bearings in the motor this winter anyway). I just want to be able to decide if I am going to run the car at Nationals or not.

Cut the filter, no shinny bits in the filter, ran a magnet through the oil and ran the oil through a cheese cloth....nothing major in the oil. With the car on the ground...you can't hear it if you are standing over the car....only if you are under it.

Drive the car without great worry. Mine makes weird noises like that if I get underneath it also. These damn motors are so close to agricultural or light industrial motors instead of silky race machines that... Just don't get too caught up in the minutia. The more I poke around under mine, the more disconcerting noises I hear. Don't let it rattle you. You are just wound up about the event.

Car has great oil pressure too. Hot idle is 40psi on a Autometer Gauge. I would LOVE to find someone that could say....I went through the exact same thing and "it was X and this is how I diagnosed it."
