I went to the CA Speedway today and managed a 13.99 @ 95.19 spinning. It was shocking since I did 18.69 on the first run with the street tires, lol. :bang:

1st Run on street tires:

R/T ....... .384
60' ....... 2.846
330 ...... 8.214
1/8 ..... 12.416
MPH ..... 57.14
1000 ... 15.965
1/4 ..... 18.698
MPH ..... 84.14

I spun the entire way trying to peddle it, lol.

2nd Run on drag radials:

R/T ....... .200
60' ....... 1.960
330 ...... 5.685
1/8 ...... 8.861
MPH ..... 76.94
1000 ... 11.637
1/4 ..... 13.999
MPH ..... 95.19

I spun a little on take off but it grabbed traction quickly and took off. I had a passenger with me that weighs 220lbs. Track officials told me not to take him any more since I ran faster than 14. :eyes:

3rd Run on drag radials:

R/T ....... .597
60' ....... 2.454
330 ...... 6.836
1/8 ..... 10.149
MPH ..... 74.60
1000 ... 12.999
1/4 ..... 15.412
MPH ..... 93.39

I spun and kept fighting it the whole way.

4th Run on drag radials:

R/T ....... .223
60' ....... 2.224
330 ...... 6.042
1/8 ...... 9.276
MPH ..... 75.72
1000 ... 12.097
1/4 ..... 14.494
MPH ..... 94.01

I spun through first a little but was ok from 2nd on.


Last time out at the track my best was 15.5 and a worst of 16.0 with a bone stock 5.3L with just tranny mods.

This time a had a low cr 408 and a 2600 stall tc. I dynoed 250hp and 290tq last but switched heads(P&P 6.0 vs AFR 225's) to increase cr a bit from 8.0:1 to ???(8.8 I think).

It was spinning just one tire so next mod will have to be some sort of posi unit. Which one is the best?

[skeet]

most will say detriot true trac myself i like the auburn pro series lsd, but then again its the only one i used

Yeh, a buddy at the track told me to get the detriot true trac. If I get that one for my 10 bolt and decide to switch to the 14 bolt can I install it in that one instead or are they different?

They're totally different. If you're thinking of doing a 14 bolt, do it and bypass any mods to the 10 bolt.

Does the 14 bolt already come with some sort of limited slip? What would be an upgrade to it?

[SRT10KLLR]

I have read that for each 100lbs removed you gain about a 10th in the 1/4 mile. Without my 220lb passenger and with the Tru Trac for traction do you think I can get it to the 13.5's? Also, maybe add Caltracs.
