Progress Report 15.46 @ 94.2 Bone Stock

[fastcar]

Greetings All,

Glad to meet you, and all that other good stuff.

Drove P71s for years, always wanted an MM, when I seized my P71 with 240,000 miles I found a 300A for $10,500 in Atlanta, flew down, and now am a proud owner! It's got 100,000, but who's counting?

I'm determined to get it into the 14s naturally aspirated (read NO NOS) and have begun what will apparently be a long, painful quest to accomplish this.

I read eagerly on dragtimes.com of all the folks who were running 14s stock, save for maybe an air cleaner or set of gears, and got my hopes up..:stupid:

Boy were they dashed when I cut a 15.46 best pass in 56 degree whether as reported by my Vericom VC 200.:bigcry:

My next post will be with a K&N FIPK.

QUESTION: DOES ANYONE HAVE THE FORMULA TO CORRECT TIMESLIPS TO STANDARD TEMPERATURE AND PRESSURE? This is the only way I see of being able to compare results on an ONGOING basis, with temperature, pressure, humidity, etc always changing...

Don't feel too bad about a 15.46 bone stock, that's a decent 1/4 mile run w/o any mods. IMHO, the K&N probably won't do much for you by itself, a tune and 4;10's will really wake up the car, and should get you close, if not into, the 14's.

With a tune, mufflers and PHP air intake box, my best was 15.13 at Gainesville during MVIV. That was first time i had ever been to a track, had no clue what I was doing...lots of wheelspin.... napping at the lights. It sure was fun though.

[fastblackmerc]

A tune, underdrive pulleys, CAI & 4.10's will get you to the mid to low 14's.

^^^What Pete said^^^^

Gainesville was my first run with the MM, and the first time back at a track in nearly 30 years, had a great time as well.

BTW, my best run that day was 15.624 @ 91.29, bone stock. I plan on running again this year at MV-V to see what the car will do with the following mods:
4:10's
DR tune
Steeda U/D pulleys
PHP CAI

BTW, the other Blue MM running at MVIV-Gainesville cracked the 11's, but he was running just a "couple" more mods than either Pete or me.;)

I wish I shared your optimism. I've seen plenty of these cars at dragtimes.com WITH those mods, still in the 15s!!!

Your car has to be REALLY HOT to go low 14s. There are guys out there with JUICE that are lucky to be going that fast.

I actually have my FIPK results, but am waiting for someone to tell me how to correct them before I post them :D

I know the other three mods you suggest will not take ONE FULL ET second off my times!!!

[gmtech]

ran 15.2 stock.....xcal2 and JLT intake took it to 14.8...NGK TR6 plugs and a little practice took it to 14.6...practice makes perfect;)

[sailsmen]

I ran 14.2 on 4:10, UD Pulleys, Tune and Denso.

A member hear ran 14.5 on a stock car w/ no mods.

[fastcar]

In this case, because the temperature was quite low, and air pressure high, the corrected time was nearly equivalent to the uncorrected time. However, in some instances it can equal several tenths.

Please everyone when you go to the track COLLECT THE WEATHER DATA AS SUPPLIED BY THE TRACK or any weather website for that day/time, and CORRECT your time slips. You will need:

TEMPERATURE
PRESSURE
ALTITUDE
HUMIDITY

Use this calculator as suggested by Mike: http://www.modulardepot.com/density.php

It works great.

Happy burnout,

15.46 sounds just a bit slow for that sort of track temperature. I was running 15.1 bone stock.

A couple of things to check: With 100,000 miles on the clock, you might think about doing a compression check on all 8 cylinders, to see where you stand.

The other thing is, get one of the experienced bracket racers at your track to take it down the track. You might find a couple of missing tenths there (staging shallow, etc.). If not, at least you'd know it wasn't in your driving.

I've run 14.31 at 52 degrees F with: 4.10s and Alternative Auto (Lidio) tune, on stock BFG tires. The tune alone should get you down to 14.80.

[SID210SA]

I ran a 15.8 bone stock in 90+ degree weather here in South Texas
I ran a 15.6 with a JLT CAI/RAI in the same weather
Then I got the Lidio Tune to go with the JLT and ran a 14.6....no other mods. On stock tires weighing in at 4375 lbs.

[OneBADLsE]

You have to take into consideration that all cars (albeit theyre the same), are different. Some are freaks out of the box. Some are slugs. I drove an 04' a couple of weeks ago, and man that car was like A BAT OUTTA HELL! Even with a hesitation i figured it felt like a VERY LOW 15 sec car!

Best of luck in your endevors!

BTW, check out my sig for my ET on my GM

[james79stang]

My best stock time was 15.29 @93 mph.... paul hp box and a 1525 super chip stadard down load.. best 14.74.. rest stock with spare 1/2 tank gas.. i usually shallow stage.. 1/2 tank gas for no wheel spin.. Jim

[fastcar]

ran 15.2 stock.....xcal2 and JLT intake took it to 14.8...NGK TR6 plugs and a little practice took it to 14.6...practice makes perfect;)

Thanks,

Plugs actually help? Some folks list Udenso, or something like that...

Slow??? Tell me about it! That's what I'm crying about. But, a lot of people report these cars to be mid 15 seconds factory - so it may be not too far below average.

Your idea of checking compression is excellent, and I will do it at some point.

I'm getting Lidio's tune this week. It sounds like the best. :beer:

Thanks for the feedback.

But, this is what I'm talking about 2 tenths from a cold air kit sounds maybe feasable. BUT ONE FULL ET SECOND FROM A TUNE IS IMPOSSIBLE. No one, not even Lidio is claiming anything like this. (trust me, I wish it WERE true ;-))
We need corrected times. The temp may have been the same on the third run, but what about the pressure and humidity levels? There is a huge difference between how hard a car will run in high pressure versus low. It's like giving the car a pound or two of supercharger.

Everyone can correct their ETs here: http://www.modulardepot.com/density.php

[sweetair]

Has it not been said yet to just put a BLOWER on it and experience being one of the only over 100k mile supercharged Marauders. Go get it and forget NA. Best of luck.:banana2:

[sailsmen]

I have said it dozens of times temp/humid +/- .75.

Thats why my sig shows temp/hum.

I laugh every time I see someone put on a mod and they say how they reduced their time by .5. Reduced what time, the one they ran 8 months ago?

Even the same day bracket racres will adjust times by 3/10ths.

[Smokie]

I was looking at my old timeslips from the beginning and your 94.2 mph trap speed tells me that a sub 15 second 1/4 mile could be possible, I have many 14.8's and 14.9's in the 94-95 mph range.

Your launch and 60 foot times are where the whole outcome is determined, maybe new spark plugs and a K/N drop in filter will help. Take junk and spare out of trunk.

I found that my best 60' times n/a were with a SLIGHT squeal of the rear tires, never a complete revolution. A very shallow stage is a must with a heavy car. No squeal at all from rear means your launch is too soft. Good luck.:)

Hi Smokie,

Thanks for your input. I think your advice is sage.

RE 60' times: I DISCOVERED THE SAME THING YOU DID: IF I SPIN AT ALL I WILL ADD 1/10th to the 60' time, and 2/10ths to my ET right there.

BEST LAUNCH: A decent squeel, NO MORE. That can be tough.

MY TECHNIQUE: (app to my car only) LOAD CONVERTER TO 1600-1700, LET GO OF BRAKE AT SAME TIME FLOOR IT.

Best 60' time: 2.64

CAVEAT: I am using a Vericom VC200, which DOES NOT LET YOU CHEAT BY STAGING SHALLOW, AND GETTING THE CAR MOVING WHEN IT TRIPS THE FIRST BEAM (which is 10 inches down the road). A shallow stage will help at the drags, but not with my computer...

CAVEAT 2: Sometimes the MPHs reported by the VC200 may be a little high. They include calibration factors to adjust for this, but I would need to test it at the strip (which I plan to do this summer) before I know which cal factor I need.

P.S. I ran WITH NO SPARE, NO JUNK, 1/4 TANK OF GAS.

Thanks for your excellent input,

P.P.S By the way, NICE CAR!

Hi Sailsmen,

I couldn't agree with you more. The community's reports aren't helpful unless they are corrected, which brings me to my question... why don't you correct yours? :D Listing the temp/hum is better than most, but it's A LOT of work for members to correct every one elses submissions. If everyone corrects there own, then we can all see right off the bat what works, what doesn't, and how much it's worth.:cool:

Let me appeal to everyone to take temp, humidity AND PRESSURE (one of the biggest factors in the calculation) and please CORRECT your times here: http://www.modulardepot.com/density.php

SORRY EVERYONE, YOU NEED:

TEMPERATURE
HUMIDITY
PRESSURE
TRACK ALTITUDE

This info is available at any track. I left out altitude on my previous post. I went to this link:

http://www.modulardepot.com/density.php

to run two scenarios for sailsmen, one with low and one with high pressure to demonstrate what a huge difference it can make, when I found you need ALTITUDE also. Yet another important variable.

Sailsmen,

Can you find out your tracks altitude? Then you can enter various pressures and see how much of a variance it creates in your times...

Hi sweetair,

My problem is, if I do this, I will need to put on a KENNE BELL. I'm a purist/perfectionist, and either do something optimally, or not at all... It's just the way I'm made. I love all those Marads out there with blowers (including yours), don't get me wrong, and I'm not a blower snob, I just cant' do an Eaton or Centrifugal.

SO, the Kenne bell for a 03 MACH I, installed, will set me back about 7-8K. I can't do that right now. But, I can dream... :rolleyes:

P.S. anyone know of someone who did this? Is he here, at MM.net???

Ok here is my correction....the third time is 72 degrees in March and in Lufkin when I got the 14.6....yes the Tune did cut a whole second off my time and I had 3 other Marauderers there who wittnessed it....Pat, Mr. Jones and RaceLegend79.

I dont get what has to be corrected....the track times you car from start to finish and that is what your time is....I understand that colder air and lower humidity can lead to faster times but how can you adjust the time that was given to you?

[SID210SA]

Oh yeah and here is the thread from that day at the track in Lufkin....

No ones doubting you ran a second faster after installing the tune. the doubt is in crediting a tune and only a tune for a 1 second reduction.

As I pointed out bracket racers will change their time by ~.3 the same day at the track based on weather conditions. My car with the same tune has run from 12.2 to 12.9. Difference being weather.

I cannot find pressure back more than a week. In the future I will show uncorrected, the common comparison, and corrected.

[Smokie]

Going back to best n/a time on just a tune: 14.49 @ 97.53

Temperature: 64 degrees
Humidity: 72%
Altitude: 50' above sea level

I was not going downhill and I did not have a 35 mph tail wind. I did have 1/2 tank of gas and I removed the spare.:D

I need to get educated on the track stuff....I dont know how the bracket racing works, what dialing in is or what a whole shot is....I am sure there is many other terms I dont know either...

Forgive me for misunderstanding......

Mike

[sailsmen]

There is no reason to be forgiven, there is a lot more I don't know then what I do know.

Bracket racing you are trying to get a specific time that is posted on your window before each run. Through out the day changes in weather alone can result in changing that time by ~3/10ths.

Point being running the same car unchanged at the track on different days can result in a .75 difference due to weather.

My car runs between 12.2 and 12.9. I am hoping to improve on the 12.2 and in the right conditions I will be able to.
