My previous trip to 1/8 I was on 28" drag radial and had a bullet type muffler and managed a 7.40 at 100

Went out on sunday with a 29.5 full slick and replaced my muffler with a big diesel magnaflow muffler. on 12psi and 75rwhp shot of nitrous till 60" I managed a 1.57 60" and 6.91 1/8 at 98 leaving on about 3psi and shaking the tires pretty bad!

I'll go out next time with a 4" cutout and see if that free's up some mph and I'll also try and leave on some more boost try and get a 6.70's out of her!

I did go to October truck madness and ran an 11.20 at 120 with a 1.65 60"

Run down of the combo

6.0 stock bottom end
Stock 317's upgraded springs
EPP cam
FTI verter
PB 60e
3.42's
PUMP GAS 93

 

The cutout will help a little bit. I would look into a set of 3.73 gears as well.

 

Should be a high 10 if it runs 122mph or so.

 

Congrats on the times. What rims are you running, And to Black you think the 3.73 would do better then the 3.42's? I have the almost same combo and I have 4.10 in mine now, was going to put 3.42 back in it. Sorry for the post

 

I plan to turn up the boost a good bit more so I'll see how the stock gears work for me. I wish I could hook on drag radials but don't see it happening
