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... :vash2:

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.

Good luck!

Go fast, fool.

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?

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."

Mine makes funky noises from the bottom too. But I always assumed it was the same as the injector noise I hear from the top.

I don't ever remember listening to the motor from under the car before. The noises are odd and perplexing. I have heard nothing through a stethoscope that I would qualify as a knock...just several spaces where a "tick" is audible. I stuck the stethoscope on the truck's, Jenny's car and the M3's oil pans. All had similar noises. I have a few other things I am going to check in the morning. I worked on this thing till 3:00am...then was too stressed to sleep...and was at work at 7:45. It's been a REALLY long day.

I'm guessing you arent doing the pro finally then. When are you getting to lincoln? I'm getting there sundayish. If you dont have it sorted by then I'm sure the two of us can figure it out, or break out into fistacuffs.

I'm not sure at this point. I'm going to tinker with it some more today and see what I can find out. Thanks for the offer of help. If I can't get it figured out I'm not going to bring it. I'll just be in E Stock showing everyone how bad of a driver I REALLY am.

Exhaust leak can be found with a hose better than stethoscope. I quess removing the tip from stethoscope makes it a hose, but extra vacuum works well too. If you cannot find anything and the mechanical sounds are not there, bring it to the event and run it. If you haven't heard it before from top, chances are that it has been there all along.

I've got nothing on the noise, but just wanted to say good luck to you and Leafy.

You can hear the throwout bearing, the trans input shaft rattling or ticking, the clutch springs, the oil pump gears, the oil pump flats against the crank flats, piston slap (I've got that one), valvetrain noise, and who knows what else. Just run it.

My head was just rebuilt and lash set, and I still have valvetrain noise. I just accept it as part of the car. Kinda wish I only had the exhaust tone though.

Here are a few videos of my car at Nationals. I was still gun shy and scared to death the motor was going to fly apart....my codriver had not taken an autocross run since Nationals last year. He was still able to pull off a 6th place finish and highest finishing SSM Miata two years in a row.

Got to meet Leafy. He's a much cooler guy in person :) His car is pretty damn fast. Once he get's it sorted out we are going to have some fast ass Miatas in SSM.

I just compared our West videos side by side. How did I beat you again? I still don't believe it. You're faster everywhere but corner entry where I could just turn in with more speed and keep it though the turn but you were on the loud pedal sooner. Assuming both of our speed readouts on the video are mostly accurate. I don't even want to compare our east runs because all of mine were heinously abysmal.

More distance? :giles:

So I have been VERY lazy with the car since Nationals. I actually just got it off the trailer a couple weeks ago.

So apparently I had the supercharger on the wrong side of the motor....who knew?

https://www.miataturbo.net/attachmen...ine=1390260157

As I was test fitting the new intake manifold....I, for a split second, thought about pissing you all off REALLY hard by twin charging the car.........with two superchargers.

https://www.miataturbo.net/attachmen...ine=1390260157

And I started to test fit the new Radiator and Intercooler

https://www.miataturbo.net/attachmen...ine=1390260157

https://www.miataturbo.net/attachmen...ine=1390260157

https://www.miataturbo.net/attachmen...ine=1390260157

That's really as far as I have made it. I have a few more things to do before the Dixie National Tour.....I hope I'm able to get it all done.

that bad boy looks MEAN

the rad/ic setup is....interesting
I remember we had discussions on whether a setup like that is effective...years ago.

Looking forward to results.

and I doubt anyone would be pissed off if you actually twin charged it lol. you seem to know what you're doing, and would probably actually pull it off

I think it would be effective. just need a divider down the middle to duct the air all the way to the bumper cover.

So your going to a hot side 'charger with a standard style intake manifold?

Love it.

other way around.

effective for an autocross car...I'm sure it will be great

Effective for a road course...I dunno, probably not enough radiator

It's enough radiator for a Honder making more HP without ducting. I imagine the rad would be fine. I would worry more about the effectiveness of the intercooler.

this means literally nothing.
you should read up on the discussions and testing some here have done proving this theory is garbage on a miata.

Don't be a chode. I used a relevant anecdote to point out that there's a likelihood that this would work fine.

Heat transfer is heat transfer. Unless some other mitigating factor is involved there is absolutely no difference between mounting this rad on a Honda and mounting it on a Miata. There is only the required quantity of heat energy to be removed, and whether or not there is sufficient heat exchanger effectiveness, water flow, and air flow. There is no magical quantity that makes a Miata require more heat exchanger than a Civic.

You're the chode. There is nothing in common between an all aluminum modern block vs an old closed deck cast iron block.

I personally rebuilt a 96 miata engine that overheated with an oversized honda radiator on it, and it ran fine for years before that, and literally the only thing that caused it to overheat and warp the head and blow the hg was the honda radiator. This was a street car too.

But please, tell me more about all the miata's with honda radiators that you've run? You ARE speaking from experience obviously, to be this confident........right?

That half width radiator fits like a late 80's early 90's honda. Not exactly modern, not exactly aluminum blocks.

Coadingparadox(sp?) Has ran this setup on his car for a couple years. With a full size 2 core rad the car never got hot, the smaller 3 core rad...WITHOUT an a/a intercooler core and oil cooler sitting right in front of it and with a reroute should be more than enough cooling for my application.

Yeah you're probably right, and like I said both you and codingparadox know what you're doing so I'm sure it will be tweaked to perfection. I just dislike vague blatantly false statements like vehicular made. What IC core are you using?

:rofl:

What planet are you on? The fact that you managed to melt down one singular Miata engine isn't an argument for anything. And, you still haven't done anything to support your argument other than get mad. I said that his setup should work, and now you're agreeing with me and still acting like I'm the dumb ass.

I'm done responding to your moronic posts and derailing OP's cool thread.
Go ask Savington, Emilio, or any knowledgeable miata company/track racer what they think about your statement and learn for yourself. The fact that you're arguing using some retarded vague blanket statements tells me you know dick all about the topic, and have all of zero experience with it.

So far the ratio of documented well working small radiator setups is slim to none. Only reason I am encouraging OP is because he's a smart guy, a competitive racer and fabricator, and I know he'll be able to overcome the obstacles that come with this sort of setup. I was in no way agreeing with you saying that it should work because it works for some street driven honda somwhere:jerkit:

Take from what what you will.

Sooo I got the motor apart to for the off season "freshen up"

I guess these pistons are in ok shape ;)

Before I pulled the motor I took thess pics......just made me giggle.

https://www.miataturbo.net/attachmen...ine=1391970761

https://www.miataturbo.net/attachmen...ine=1391970761

I hope to have it back together and in the car next weekend.

When just one won't do?

https://www.miataturbo.net/attachmen...ine=1391994684

Why does this feel like someone needs to add the Xzibit "Yo Dawg I heard you like superchargers" meme to the above.

and from the rear (Really shows how quickly the car accelerates)

While your at it,why not remove the rest of the cooling elbow in front of the engine and put a freeze plug. That's nice stuff inside your bay !

Not bad for making less power than the old setup.

The Miata lives again. Just started it....stared on the first crank. Spare blower is on the car, new transmission installed, new clutch and pressure plate installed, new lower temp thermostat installed, new 36-2 crank trigger wheel installed, new shifter in (the new gearbox combined with this shifter....feels like a bolt action rifle).......I think I'm going to take a short breather and finish up.

Today is a good day. Finally got ours finished up today as well and it started on the first crank as well. :)

So here are a few pics of a couple projects on the car.

Hate away on the blower car.

Now does it not misfire under load? ;)

If you look close at the picture of the engine bay....which was taken today....the cams are spinning....so....yea. It runs.

Nice edit Leafy.

But no...it doesn't still misfire under load.

Are you venting the valve cover to the supercharger intake through a catch can?

Yes

It might be better to vent the gasses to atmo instead of going into the intake with them. Oil vapor has a lot lower octane rating that gasoline and the chance of generating knock in a supercharged car is greater than if vented to atmosphere.

I miss the dryer hose. Have you killed any coils yet due to the heat? Is that still a stock power steering pump?
