MPH Differance...

[us7race]

Ok here are my runs from Saturday...
There are no 60' they were down...

330' 594' 1/8th MPH
4.0072 5.8590 6.2692 109.72
4.0373 5.8881 6.3013 108.92
4.0260 5.8839 6.2998 108.20
4.0368 5.8922 6.3130 106.96
3.9991 5.8499 6.2691 107.33
4.0102 5.8511 6.2680 107.93
4.0039 5.8468 6.2721 105.80 Lifted

So it has never ran 109mph before but it was cooler weather. (very good air). So my questions is why the differance? I run a Hydraulic Oil in my glide and I was thiking with the cooler temps and it being the first pass the fluid was thicker and worked better causing it to ET better?
I am thinking of putting in some ol' type F and seeing if that makes it either closer to 109mph or at least more consistant. But would like some opinions. I have been running this fluid all year. Never really noticed it before but I have had alot of other issue's so it may have been there and it went unnoticed... Thanks Guys.

Here is a Video from the 1st pass but it was of the tach to see the RPM's at each point..

My kids run a little 65 Nova that turns times very close to yours. On a tipicle run, he goes 1.33 60 foot, 3.96 330 , and 6.20 at the 1/8 th-- his MPH is from 108.76 up to 110 .20. I do not think that the trans oil will change anything-- How hot do you run the engine water temp before a run ?? They have a powerglide but he is going to try a 3 speed since the track where he goes has such good bite on the starting line- Is yours a three speed or powerglide ?

It is a Powerglide and the temps are about 140° before the burnout.
The motor never gets over 180° on the hottest days and lately never over 160° My truck weight is 2865 Wet..

In the olden days, MPH was a tuning aid for jetting. Considering your runs #1 and #5 were almost identical ET and close to 3 MPH difference, could it be you're a tad rich in high gear main circuit and the cooler air made it more close to ideal? In air the same as #5 you might jet lean 1 or 2 sizes, depending upon your set up and see if MPH picks up. If it does, you're going in the right direction, if not jet back up. I always figured better to be a little fat and drive it on the trailer, than lean and winch it on the trailer.

Larry, your program is very neat-- I am not too familiar with the 1/8 mile stuff- but they do give the 330 MPH-- and if I can recall that, the 330 MPH was 87 something- We did change the rear end gear for the 1/8 mile, but it did NOT change the performance at the track-used to go 6500-6600, now goes 76-7700 in the 1/8-- The last thing he tried was a much looser coinverter- was 5000 stall, now is 6800 stall-- that was a gain of .20 seconds in the 1/8-- 6.40 down to 6.19 with the converter change.. Again, your program is very cool.

Thanks Joe !

here's a few Pics ,.....around your 87 MPH @ near 325 to 327 feet

[us7race]

That is very cool software. I guess you put in all inputs or just some?
Looking at it i am kind confused. I have had passes like this...

60' 330' 594' 1/8th MPH
1.3229 4.0008 5.8590 6.2790 107.13

So how does it compare?

This pass was at Ohio Valley in Louisville, KY
The others were at Windy Hollow in Owensboro, KY

yes...you can Input any single distance ET
or any combinations of ET's
or all the Incremental Feet's ET's for greater accuracy in Modeling.

it takes a minimum of 5 Inputs to achieve good accuracy ,
like->
60 Ft
330
660
1000
1320

its just a "rough-draft" version i'm working on updating
to include inside PipeMax 4.0

in PipeMax 4.0,

it will be
60 Ft
330
( 594 from the 660's MPH )
660 ET
660 MPH ( which determines 594's ET )
( 934 from the new NHRA TopFuel, etc MPH )
1000 ET
1000 MPH
( 1254 from the 1320's MPH )
1320 ET
1320 MPH ( which then determine's the 1254 Ft's ET )

so a possible of 11 Inputs to describe the 1/4 Run
the accuracy should be a bunch better than i'm now Posting
especially for TopFuel + FunnyCars where a few thousandths of a second
accuracy is required to model or correlate the MPH and GForces

so any single or any combinations of those 11 Inputs
will calculate the rest of the Times/MPHs/GForces, etc.
