bluesmini,

Does that mean you can get Coke to donate some drinks??? If not, I'll be bringing whatever is cheapest!!!

 

Hey Gang - Not to hijack or anything - But, I've got a thread going in the marketplace for some used wheels. I'm down to 2 s-lites left. If anyone is looking for a good emergency wheel I'd be happy to bring them with me.

We now return you to your regurally scheduled thread......


Eric - It'll just be me. The other guys can't come out and play

 

Just wondering if anyone might be joining me for breakfast at the Bojangles at the intersection of hwy. 70 and hwy. 321 on Saturday morning. I will be there by 8:15. Hope a few of you can make it. See you all on Saturday.

Eric

 

Sorry guys, but I may back out of this event. I'm going to wait until morning to make the final call, but right now they're predicting some potentially nasty weather up in there for tomorrow.

 

Eric-

I too need to play this by ear Saturday morning. As usual, you never know if Hickory will get slammed with a 'wintry mix' (as they like to call it), rain-turned-to-ice or just simple rain.

My worry is the predictions indicate it will get colder and more snowy in the afternoon, so getting home may be the 'interesting' part.

I will check this thread in the morning to see if the event is postponed or updated.

I'm going to risk it an head on out. If this event gets called off when I'm out on the road , please give me a call on my cell # 336 508-3824. Thanks
Roland Aber

 

I'm heading down from Asheville. Weather reports looks like the snow and freezing stuff will stay north of Hickory.

 

159 any one else brave enough to post.

 

That is without a pulley!

Here are some pics.

 

i can't get either of those links. a little help?

 

Try again, they seem to be working now. What error were you getting?

 

Thanks to everyone who "braved the elements" and came out for the Dyno Day. It was a lot of fun and very informative. We had 7 out of 10 show up which was actually good. Not sure I could have made it with 3 more cars! It took me a few hours to recover. I trust everyone made it home safe and sound. Thanks for the pics Chris. Dinner at the Boxcar Grill was also very good. Best fried oysters I've had in a long time.

Here's may result: 154 with the only mod being a Promini air intake. Not too bad when compared with some of the others. I was real surprized in the difference Chris B. got after switching out with the K&N intake.

Guys-

Just be aware that Aaron told me at the VERY end of the day that the Mustang dyno's calculations are directly affected by use of a gear very close to a 1:1 ratio into the final drive. He was under the impression that FIFTH gear was closer to a 1:1 then 4th on an MCS, which is why he ran all the runs in 5th. That may explain why all of the results were consistently low. He told me that if 4th really is the closest to 1:1, then we should find out the difference between 4th & 5th and multiply that difference across the data points he intends to email to each customer.

Unfortunately, every one of the documented ratio lists I can find seem to multiply the final drive with the individual gear to give an 'overall' ratio, so I can't tell which gear is closest to 1:1 cause I don't know what the final drive ratios are. I get the feeling that neither 4th nor 5th is a true 1:1, but we really need to know which is closer, cause you don't want any more gear reduction or multiplication skewing your results then is necessary.

If anyone knows of a proper gear ratio list, please post a link. Otherwise, I'll start a thread to try to get the actual gear ratios for both the pre- and post-'05 MCS, as well as the final drive ratios.

Wish I could have been there. Been stuck in OK for the past several weeks.

I did have mine done locally, but it was on a DynoJet. Curious to see the difference between the 2 machines.
If I remember correctly the pulls were done in 4th gear.

 

174

15% pulley, Miltex cat back exhaust, Denso IK22 spark plugs, JCW CAI and 380cc injectors, JCW software. 10,000 miles and 5 track days.

Goldfinch2's high number of the day can only be attributed to the following:

1: Most parts obtained from Webb Motors as opposed to the same parts
from another supplier.
2: Its not what you do but who does it.

 

I'm a little baffled on the lack of HP developed on my car: 156 best pull.

I don't think my numbers will offer a valid comparisom with other cars. For my first run, we were still deciding what RPM to do the runs at so we stopped at 5700 while everyone else went to 6500+ so it only hit 141. The second run I might have been a little heat soaked, but did go to 6400 RPM and we hit 148. My last run had a bit of time delay, as I changed out the intake and that's when we hit the 156.

I spent most of yesterday trying to figure out what went on. Granted these numbers are wheel HP and if we do the math it'll make us feel better but still, I know a lot of us were expecting more/larger numbers. Then it hit me on why the large differences amongst cars; has to be the gearing. The newer gear ratios in the 05's and above might put 5th gear closer to the magic ratio number.

Based only on the time difference it took for my 02 to go from 3500 to 6500 and what it took some of the newer models, I'm thinking that 4th might have been a better choice for my car. I think it'll be interesting to see everyone's numbers and see if the 05's and newer ran better then the older model years.

Here is what I was able to come up with for gear ratios. Numbers are from the MC & MCS Product Brief Book for 2004 and are obviously for the MCS.

1st = 11.425
2nd = 7.181
3rd = 5.397
4th = 4.4073
5th = 3.656
6th = 2.966

02 MCS, 15% pulley, Invidia Cat back, Bosch Platinum +4 4417 plugs, currently with a K&N typhoon intake (Run 1 & 2 had a ProMINI), standard software and 90,500 miles - Plus I was running with my Snows on

 

These are the effective, 'overall' ratios that keep getting posted, where the final drive ratio is already multiplied against the individual gear ratio. So, it does not help to find which gear is closest to being a 'non-reduction or non-overdrive' gear unless you also know the Final Drive Ratio(s).

Also, keep in mind that some cars actually have TWO final drive ratios, that change depending on which gear you are in. I'm not sure if this applies to the MCS.

From the same Manual

Final Drive ratio; 2.74

 

Hey Smoke-

2.74 - !?! Man, I seriously hope NOT! Should be in the high 3, low 4 range - like a 3.90 or 4.11 or 4.40, etc, or there's got to be some other reduction gears involved somewhere.

At 2.74, 6th would be a 1.08:1 ratio according to your previous post. That would mean that not even 6th is a true overdrive gear. 5th would be a 1.33:1, so there would be NO way anyone would get accurate dyno readings on a Mustang dyno, even in 5th. Most 6-speed cars are very close to 1:1 in 4th gear, with 5th and 6th being successively taller overdrives.

As a comparison, my old '88 CRX (non-Si model - no VTEC) did have a 2.78 final drive, and it would run about 2100 RPM in 5th at 75MPH. This is a real 'economy' gear setup, and I really doubt it applies to the MCS. The CRX Si had a 4.10:1 final drive.

Dat's what the book says.

2.74!

I'll be calling the dealership this AM and talking to Brent or Henk. I'll see what I can come up with??

 

Sorry to be one of the 3 who didn't "brave the elements". With the forecast what it was, I decided caution was the better part of valor.
The numbers coming up are consistent with the results of my past dyno experience with my MINI. That was also done on a Mustang dyno. The outside temp would have been similar, but my pulls were done in 3rd. The average for 3 pulls was right at 150. The mods on the car were just a Madness intake and the Magnaflow.
