Got a chance to finally get out and race in some good cold air. Anyways, I trapped 93-94 on motor and 103-104 on the juice, my highest being 104.41, what do you all think that would be in teh 1/4? my calculations put it at right around ~131. does that sound about right?

I always use 1.55 for the ET and it always works out really close for me, so im covered there.

I know, its a damn shame that the local 1/4 mile track wasn't open last night.

i would say that is about 130 mph traps in the 1/4 mile

damn chris, what did you do to step up your game?

This is what I came up with as a theoretical pass based on that 1/8th mile MPH:

60 Foot 1.41
330 Foot 4.14
660 Foot 6.51
660 MPH 104.41
1000 Foot 8.56
1/4 Mile ET 10.32
1/4 Mile MPH 128.43

typically, you pick up 25-26 mph from the 1/8th to the 1/4.

when I trap 102 in the 1/8 it is 130 in the 1/4.

Your a 6 speed Chris...that MPH in the 1/8 is gettin it.

I have several timeslips here with 104-105 eighth mile traps and from 131 to 135 in the quarter. Anywhere from a 10.3-10.5

closest example I have is:
1.553
6.788
104.54
10.482
133.51

Keep up the good work and you should be bottom 10s. Just remember to use 100 or 104 unleaded.

When I was cam only with a 100 shot I went 10.49 @ 129.06, the 1/8th mile mph was 103.11, so you should be around 130, maybe a little higher since ur a 6-speed, here's my old slip:

dunno if this helps, but this is what i ran last weekend.
Stock bottom end, heads/cam, bolt on , th350,150 wet shot, leaving at 3200 off the T Brake, 3.73's , 8.8 rear, w/ 325/50/15 MT Drag radials. race weight around 3500#

60' 1.374
330' 4.165
1/8th 6.507
MPH 104.87
1000' 8.536
1/4 10.259
MPH 130.51

that was the first nitrous pass i made on the th350, and it has a 4200-4400 stall, so it has more left in it. just gotta wire the nitrous up, so i can do a full T Brake launch

What did you run on motor, how much were you spraying?

383LQ4SS

iTrader: (33)

this was with my old 383 setup that made about 420 on motor. I usually ran about 11.4-11.5 all motor at 120-121.

The 10.4 timeslip above was probably with a 75/75 dual stage for a 150 total. Although it was so long ago I dont really remember. Ill have to look at the back of the timeslip to see if there are any notes on it.

With the same setup and dual stage 100/100 (200 total) it was 10.0 at 138 and 6.4 at 107.6 in the 1/8.

With that mid-track MPH I reckon you will be trapping 142MPH

Damn Chris 104.x at 1/8 mile is enough to trap over 130 mph at 1/4 mile buddy & i think LS1tech members already proved that

Btw do ya have any footage from that night ?!

peace

Although not exact (M6 varies from auto's), but a good ballpark is multiplying the 1/8th mph by 1.26 or 1.27

Those estimates are close to what my car ran last year with my old setup. I ran quite a few passes and on the 175HP jets the slips looked like this:
1.52 60'
6.52@105mph
10.23@132mph 3.42 gears with 325/50/15 ET Street Radials
200HPNX
1.53 60'
6.50@106mph
10.17@133mph

Thanks for all the replies! looks like I will have to wait till next december to get anymore cold air down here to find out. was at the local 1/4 mile yesterday and it was about 30-40 degrees warmer than the night i trapped 104-105 could only trap 100-101 yesterday in the 1/8th and the 1/4 mile traps were 127-128
