Don was running the shaved and used 17" triple 8's 245's from last year i think.
A set of new a-6 hoosiers would get him around a little faster!
Scott the 09 trans and the pre 09 diff is the perfect combo for me.
Not only are 3-4-5 so much more usable but 6th is a real overdrive.
4-5th close ratios is were i am really impressed.
BUT THE MOST IMPRESSIVE PART OD THE 09 TRANS TO ME, is the downshifting.
Ratios are so close, very little to no throttle matching is required. That means one hell of a lot in a high speed to low speed turn. Several guys that rode with me (John, Lavent and Brent) said it was like a dang paddle shift car. The transition from a 130-135mph straight-a-way speed on the back part of RA to the 70 mph turn at 10A where i go from 6th to 4th was so effortless i had a hard time adjusting. It really was amazing.
Not only the ratios but the shift gate is wide enough that it makes it much more comfortable in having confidence in being in the gear you like. No more mixing up 3nd with 5th or 4th with 2nd:0!
New suspension --i have a set of the KW V-3's now. Took some dialing in to get it the way I want.
Will you be at Roebling?

funny.. 04 car wit a 09 tranny or a 09 car with a 04 diff? or just see what a 2010 speed 3 does on track!
wish i could figure out how to do both.i cant wait to see how the next three weeks play out..

come on over..
you can run my 8 for a day.. i will run the ms3.. then we can swap..
REALLY.. i am serious.. the rx8 makes you easy to learn good habits..
or that is what i think.. all the above are way faster, done it longer, more talented than I, but damn i seem to have just as much fun..
****, at the last roebling event. denny had a beer or two!

Bret--dude --didnt mean to sound like i was ragging ya or something.
No one is born knowing.
RR is a really great track to learn on also and a Guaranteed good time will be had. Plus it is not expensive with plenty of track time. less than $250 for the entire w/e.
We will take care of ya----southern hospitality demonstated!
We are going to have a large turn out it seems!

Wow . that would be so cool .
I discussed it with my wife and got a reply along the lines of "not f'n likely " . I think i might have heard the word "priorities" a few times mixed in with a few other choice swear words . I think that all meant no, but I'm not sure LOL .

Sounds tempting as long as southern hospitality doesn't equate to "squell like a pig boy!"

may 1-2 with Darkside drivers education.
Darkside Drivers Education.com
$227 for the full w/e--long periods of track time and excellant instruction.
Roebling Road is actually my favorite track. Safe track with the highest average speed of all we go too.
we had an outdoor movie theater last year with track vids shown. Fun
It also includes a very excellent supper saturday night for $10.
We all share rooms so that cost is very low--maybe $50 or so.
You come and i swear on my Corps bootcamp graduation book that you will have one of the best times you have ever had with a car. Bring the family--many do.

no problems here
running a cooler "bar" plug---not the rx7's
I dont think we have good enough ignition(oem) for the rx7's plug--just my opinion.
Dont you have to run the rx7 plug without any washer?
Hey I just discovered something --my s.c. is surely sensitive to belt tension. I had it tighened just a tad for the track and it became much more noisy at idle. I loosened it up so you can turn it just a little more than 90 degrees and boy is it now quiete. Not getting any slip that I can hear see with boost gauge.
I also found that by replacing the s.c. oil frequently influences the idle noise.
anyone else?

I got the car to fire up last week by pull starting it. It didn't want to idle on its own for the first min, but after revving it a few times it idled on its own. I immediately stopped at the end of my street after getting it to start. Keep in mind that this was the first time it has ran since last year. Once I was satisfied that it would idle, I drove it @2.5 miles to a local gas station, doing a couple of "mild pulls" in 3rd and 4th gear, never going over 1-2lbs of boost. It ran fine. Once I stopped at the pump it idled on its own for another 2 min. I had my wife following me in the truck and I got out to talk with her and left the car idling. After @2.5min of idle it shut off. It would not start again. I had the wife tow me back and attempted several pull starts along the way. Sometimes I would leave it in gear even though it wasnt' actually running. It was either that, or have little brake pressure. I am assuming that flooded my engine once again. I was using rx7 plugs in the lead position and 8 plugs in the trailing. I deflooded the motor and tried pull starting again. No joy. The plugs were brand new, so I am not sure if they are fouled. BTB, I have the MSD 8247 coils installed. I have had them for @3yrs now, but I do not think they are the problem. I tested each coil w/plugs out prior to the car firing up and they all "had" spark. My plan at this point is to purchase brand new oem plugs, deflood, and attempt to crank. I cannot pull start anymore unless I wrap my tow line around the crash bar(front nose is off) due to my wifes inexperience towing. She couldn't keep tension in the line and snapped the threaded end of a tow hook off in the crash bar..HAH!

You are correct. The leading fired while the motor was turning. Does it sound like low enough compression to justify a rebuild?

I dunno. What are the numbers?
The particular situation about a low-compression motor is that the only things it wont do well are idle and start.
Once you are over 3k RPM, it doesn't really matter all that much.
I made just as much power on a motor that had less than 50 PSI in one housing (less than 80 in the other) as I did on a strong motor. It was just hard to hot-start.
Actually, that is the motor I have in the car right now. It still sucks down over 430 g/sec at 7200 RPM.
Glen over here at AZRR told me about a motor he built once with Paul Yaw with no apex seals.
Not bad apex seals. NO apex seals.
It was difficult to start and wouldn't run below 2k or so, but once it was up over 3k, it made normal power.

Get a new set of Mazda plugs.
Gap the plugs to 032-034
I do not know if that will resolve it, but those plugs are wrong.
Compression test?
Fuel pressure?
MAF clean?
20 taps on the brake recently?
Plug wires?
What do you use for a tune?

some use the rx7 plugs with no problems--but if i am not wrong they also have upgraded ignition systems? They do burn out (for the lack of a better term) pretty fast but they are cheap and have a colder heat range. They can work.
The msd coil I hear mixed reviews about--but the main thing is --if you dont get the dwell time right then they have no benefit. I dont think anyone has shown if the actual spark with the msd's(or even the ls/yukon) is equal, worse or better than the oem without dwell adjustment? I think maybe the life expectatcy is better.
But dude if your car was running good when you put her up--then she should run good now.
May need a mazda decarboning session?
Let us know what happens.

I hear you Paul. There are many testimonials that the ls/yukon/msd coils make a difference, but when it comes to proof -- testimonials dont count. I myself believe they are better but i have been more leary of posting that something is "better" without something to back me up.
You know I wish someone would run a scope on the
oem's
oems with twin fire
ls2/yukon set up with oem dwell
same with modified dwell
ls2/yukon with twin fire
then that would answer all the ?'s
I wish i had a scope.
