I got my grand national in the fall last year. I took it to the dragstrip the last day they were open.
Ran 12.63 @ 103 on 20#
340 pump Hotwire kit
42# reds 93 chip
Stock turbo injectors and down pipe open down pipe
275/60 15 drag radials 1.64 60’
Built Janis 200r 2800 conv.

~~~~~~~~~~~~~~~~~~~~~
Now I have a TT 110 chip Going to probably end up around 27 or so pounds
Ta49
GN1 super extreme
RJC 3” DP

I plan on hitting the track when they open but what are your guesses on what the game will be Just thought this would be a little fun on a rainy winter day :)

I figured several would weigh in because this is probably a very common combo..
Your car is performing quite well,very solid. This is a good place to start. There's not really anything to say above and beyond what MR.Spool has said other than You're gonna love the difference between a turbo that is just about out of breath at 20 psi. and a turbo with big lungs at 27.

Beg, borrow or steal Powerlogger. Assuming you have Erics 5.7 race chip, you'll likely note the low gear 02's...1st and 2nd gear...are pig rich. Drop the low gear 02's down into 780 territory...and bump the low gear timing in SMALL increments. Watch your 330 ET drop...and your 60 foot should drop. Dial in your high gear 02's to around 780 at the traps...and leave the high gear timing on Erics default. I have a couple of vids on how to adjust Erics chip on my channel.
