Quickest Lincolns of Distinction - DISCUSSION

I have a few stock air boxes in my garage. I will send you one free of charge if you want to do a test and tune with the airbox vs. conical setup, i'm very interested to see what happens back to back runs.
 
Problem is my conical setup includes a Pro-M 80mm MAF and CAI for which the car has been tuned. I'm not sure what influence that may or may not contribute.

Do you have the MAF as well in a stock airbox?
 
I haven't seen proof that cold air intakes provide colder IAT temps on a Mark VIII. And what exactly is a cold air intake, a conical with a heat shield is generally not considered to be a cold air intake. Now the setup Driller has is more of a cold air intake however is that setup better than a conical/heatshield when you consider the bends it has before the MAF? I want to see some data logging of IAT temps with multiple different setups. As for the weather, the temp/humidity, density altitude and barometer play a huge role. At 35 degrees and the barometer over 30, that's almost like a slight supercharging affect the cold dense air provides.
 
430 geared 4000 stall mark 8 lincoln with the stock irs and it had widened stock wheels 16x10 with 28 x 10.50 hoosier and i sprayed a 200 shot nitrous express on top to run a 11.16@120mph on a 3850lb lincoln with a 1.561 60 ft time....1.65 on the 150 shot an 171 on the motor ..i ran 12.80's on the motor with the 26 x 9 drag radials bfg 255/50-16 the 2nd pass 200shot i broke the left axle at the line. this guys name on corral is hottrodtodd

cold air entering the maf=colder IAT
IAT=intake air temperature.
Seems pretty straightforward and simple, no need to overcomplicate it with "I never seen proof".

I personally never saw proof that peanuts were in peanut butter, but I'm almost positive they are in there.

P.S. I am the stock air box on my car.
The gains from the C&L were marginal and unproven at best, IMHO it's a waste of money.
 
I never said you need a C&L, I had the stock mass air setup with a conical on my 95 LSC. Also, I should have phrased the IAT thing differently... I haven't seen proof that slightly colder IAT readings will make a difference in the 1/4 mile.

If you have a slightly colder IAT then in some PCM calibrations there are scalars that allow more timing to be added for colder IATs.

There are a couple of scalars that reference IAT's so there is some merit to IAT temps and some gains to be had if you utilize the IAT scalars.

In the stock mark 8 calibration, the spark adder for IAT isn't used.. but could easily be populated with temps in the useable range and with values that could/would affect or increase performance.

Generally speaking, of course up until the "deminishing gains" scenario.. more timing does affect 1/4 times, unless you are "at the limit" or.. your car doesnt LIKE more timing.

There is also a high speed fuel enrichment scalar that is also not used in the stock PCM calibration that could also be populared with values that would increase performance and affect 1/4 times.

lots of unused stuff in the stock PCM, with alot of potential gains to be had if alot of this unused stuff was populated with values.

Wow...the 60's times are nice. I dont think ive ever broke my 2.0 60 foots. I can't hook it up and need more grip or boxed IRS mods to frame to eliminate tire spin. Does your charger pull off the line or more when you get it spooled up around second gear? I guess it really comes down to the stall speed youre running and size of gears in the rear, where the sweet spot is for the charger or pulley size for that matter.
Are you still running the same tires? Or did you switch to the Drags? I want to switch to the Drags, but at 100MPH they are too loose fo rmy tastes at the top end when you let off the gas. Well at least thats how i remember them with my 79 Trans Am 455. You had to back her down slow and easy.
 
The Hoosiers I run aren't too bad at the top end. I generally start at 17-18 psi and drop the psi feeling my way each run and end up 14-16 psi depending upon the track.

I envy those with 1.8 sixty foot times.
 
I had too many mods done to the Mark between track visits to determine what changed my 60's the most, by the couple 10ths. I was around 2.0 before the mods. Never made it into the 1.9's before the blower install using 410's, trak loc, and the DR's.

What did I have done you ask? The transmission was totally re-built with extra/new clutches and steels, the PI tc was re-stalled to 3600, new rear diff and pinion braces, and of course, the blower and all the supporting stuff for it.

My 1.865 60' was done using the same MT ET Streets DR's used last year at SSHS6, with 20 PSI in them. I have to check, but the lowest 13 PSI used at night in them did not make the 60's any better than the 20 PSI run during the day. The track did change quite a bit though from day to night.

The car drives a 100 times better at the track with the DR's, than on the street with the stock tires during a launch. It launches hard and straight at the track, and when the SC takes over when the RPM's are moving 3k and up, it just keeps pulling all the way up to red line. I do not notice it running out of steam by the end of the quarter.

I think it needs more gear, but, will live with what I got :)

made it to the track again, not as fast as i was hopin for but got a new best e.t. i was bouncin off the limiter around 90mph when last time out i was trappin 93, oh well, more work to do i gues
