    Nitrous activation

    Steve pretty much hit the nail right on the head. That's exactly how mine is set up and it does exactly what I intended it to do. Im not going to say any size jet is safe by any means. But I ran a .026 jet my first time and it literally did nothing. I wanted to get the 11 second pass so I...

    Nitrous activation

    some photos to give you an idea. I dont know much about the boxes I never even opened them. They make solenoids for a purge too but I didnt bother setting up a purge

    Nitrous activation

    I bought the ZEX set up and basically used about half the parts it comes with. At the time I wasnt sure what I needed so I went with a whole kit but its pretty basic. I did not use any of the progressive boxes or anything, I just wired a momentary type button to the solenoid and did it like...

    stock bottom end 11second pass

    Still holds rail pretty damn well but maybe it just limits the fueling a tiny bit I had a .72 jet and I started spraying after I locked the converter in 2nd gear. Held it through 3rd and 4th than let off, I was afraid the 5 shift would have brought the RPMs down further than I wanted to be...

    stock bottom end 11second pass

    Thanks guys! I'm Pretty impressed how well it's held up so far. My thoughts are sticking with a stock single cp3 and keeping power up high has helped with keeping it alive? I know it's a crap shoot at that level I've never had it dynoed but I'd like to think its somewhere close to 700hp? I...

    stock bottom end 11second pass

    Finally hit the 11s this weekend! First run I sprayed to an 11.8. Backed that up with a 11.9 fuel only. 60' were trash as usual but I'm just stoked to be in the 11s with this truck. Nice cool air does wonders.

    Keeps getting faster

    That's impressive on a stock motor! Who do you have for tuning?

    60' questions.

    In slow mo you can see the truck squat quite a bit in the rear which takes the weight off the front and that's when it starts to go haywire. From there on its shot it also starts to rock back and forth from side to side. I'm trying stock tires tonight we'll see how that goes.

    Quest for 11s stock motor

    I'm in the same boat as you. Trying so hard for that 11.xx struggling with the 60' to get there. I'm pretty close to sea level so I'm hoping it will happen before my motor has had enough.

    60' questions.

    I might throw stock wheels on the truck this weekend and try again. I think maybe the big offset on my 20s are pulling the front end around a bit. Not sure if anyone can see it in the video but it squats pretty hard and that's when the front wheels start to toe in and out Sorry to the OP I'm...

    60' questions.

    60' questions.

    Traction bars out back What's your set up? I pretty consistently run 7.6 @88 -89 Just can't get the 60' to make up some time on the big end.

    60' questions.

    10pounds is about all I can get before it really gets hairy. Sleeves and DHD brace. T bolts out and it have 2" drop shackles in the rear.

    60' questions.

    This past weekend I tried 20r 25f with 420s and the front end still danced around pretty hard. Tried 32 all around weeks ago. Same thing, pretty hard hopping.

    which wheels do I run?

    Maybe I'll run the 420s again with lower pressure see if I can get more than a 10psi launch. I'll be spray a small 35hp shot if needed. Being a stock bottom end I need to be careful. Whatever timing is in the race tune from Kory. He didnt feel the need to pull timing.

    which wheels do I run?

    Yeah I'm not sure if it's worth switching them around. If I could get a good launch on stockers I think I would be able to knock off some time. I need to loose .15 Probably be the last time I run this year 265/75/16 on the stock wheels I've seen a couple guys get down that low on 420s but the...

    which wheels do I run?

    Im getting my truck ready for XDP diesel nationals this weekend at Englishtown. Right now I've been running my 20x10 BMFs with 420s aired down to 32 psi ish. not horrible 60's. 1.79 or so but I am wondering if I'm loosing a lot with all the rotating weight. I'm debating on running my...
