track heades gotta question 1/8th to 1/4 comparo's

[type R]

so ive made alot of passes on my car and come to know and expect some things based on what goes on in the 1/8th...
1st: my car is a sport shift auto and im in 3rd before the end of the 1/8th and remain in 3rd through the 1/4 3rd is good for 113mph +
i have over 300 passes in the 1/8th and 100 in the 1/4

2nd i average 21Msph pick up from the 1/8th to the 1/4 with an occasional 22
with some of this in mind,can i make any assumptions about my previous best runs versious new...here are some break downs

previos best 1/4 :
2.068
5.869
8.930
@79.85
11.583
1/4 13.794
@101.54

current best 1/8th
2.013
5.650
8.647
@81.53

obviously im making more power now...but i guess my question is...as power goes up does the gain in mph go up or does that remain more constant ? and if you pick up 3/10ths in the 1/8th how many 10th do you knock of on the second half...
looking for good guesses

13.36 would be my guess.

i would guess 102 so i go 8.930 at 79 to a 13.7 @101
then i go 8.6 at 81.53 only to go 102?

Just go to the track and find out or do a calculator to get an estimate. I 'm not Ms Cleo.

Pretty sure some of us are going downto BMP Sat 19th for test and tune. Why don't you bring it and find out for sure instead of guessing. Besides you'll have a blast hanging out.

Besides you'll have a blast hanging out.thats easy enough...just find a day off that coincides with T&T at bradenton then drive 100 miles...im looking for the right weather///50 or below

I guess this means no. 50 or below. That is unlikely to happen anytime soon. Besides I put down my best pass at BMP at the last track day and it was humid and in the low 70's high 60's and I drive a boosted car. I do not think weather that cold will actually help you on a N/A car. Tell your boss you need the 19th which is a Saturday off and lets see what it will do.

:roll: Yes because everytime you race on the street its in those conditions.. quit making baby excuses and go to the track. jesus, it really isnt that hard.

colder denser air will help an NA combo almost all of the time.

It also helps a turbo car but there is one other factor he has to consider.
A 50 or below temp will kill his traction giving him a poor 60ft. Especially on a FWD car that I've never seen run on anything but street tires.

last time out at sunshine was 50 or so maybe 55* and went a new pb of 1.979

Go out to BMP tomorrow nite. The weather is looking great. Even without new mods, it's gonna be a lock for a new best.

One of the best converter programs I have seen, usually is right on for me.

If I put in my new personal best from last night 8.100 @ 85.54 it puts me at a 12.64 @ 107. I have used that calculator before and it was almost perfect. Of course it can't factor in weather or track conditions but it was very close.

Yep it is always close, I have taken dozens of full 1/4 mile timeslips and plugged in the 1/8th info just to see if it would be correct it is was always right on to what my timelips already said.


I cry everytime I punch in my timelsips with good 1/8 mile times (6.64 @ 104 for example) but I did not have enough converter / gear to make it past 900ft..

lmao, that calculator is so far off for me it isnt even funny!

It does not like you or anyone who makes fun of Jesus. Now cut that out. Seriously.
