Well .1 off your 60 foot its probably .2 off your quarter mile time. I have no idea what JDM's 60 foot is but say its 2.0 on stock KDWs and 23" rims, if you can pull a 1.9 or even 1.8 then you would lose .2-.4 off the quarter mile time.
Making a 12.6 a 12.4-12.2 time. If they are having a 2.1 60' it would be 12 flat. However if they are at a 1.8 or 1.9 right now then all that I have said is null. I doubt they can do that on street tires, so my guess is their 60 foot at best is 2.0-2.1.
Pulling a 1.7 or 1.6 60 foot would be one hell of a time, dunno what that truck is truely able to do though. When I go to the track I pull off a 2.2 or 2.3 60 foot because of zero traction, however once I go wide open throttle I've noticed against whatever I'm racing if it runs a 13.9 or 14.0 my truck never gains and never gets pulled on. If I had a 2.0 60' instead of a 2.3 and take off .6 of the quarter mile time I'd be right at 13.9 which I believe is right for my truck. If I had drag radials I feel confident I could pull off a 2.0 60' if not a 1.9 and get that 13.9 timeslip.

I have the saleen 23's on my truck right now and once I get her all built I am going to have a spare set of wheels for when I take it to the track or just feel like having a little fun. As for me, I am building a show truck so numbers are a factor and could help me obtain more sponsors and draw more attention to my truck. I am going to get some centerlines and put some DR's on there. Probably a 315/35/17 on the back and I'm not sure about the front yet.

JDM's truck was pulling 1.9 60' I beleive. They posted what their 60' was on here somewhere.

On a different tangent....
A member on here had previously told me that he ran a 13.5 in a FX2 Screw with a Magnacharger that only produced 8psi part of the time and 10 psi the other part. It was only producing something like 380/410 and was running on 28"(I think) drag radials.
All the talk that's been thrown around in this thread screams BS on the above statement.....doesn't it?

I am assuming you are talking about me and you can think whatever you want-its not BS. It never made 10 psi-8 psi max and when I tuned it it was making right at 400 rwhp. It is a 2wd FX2 Screw full weight and ran 4.10's and a 28" M&H DR. It would go through the traps at about 5000. Here is the timeslip and video. Go ahead and call BS now.

What size drag radials were they? I was looking at the M&H 345/40/18s myself.

I am slower, but I have less power and more weight, and I can drive mine in the snow/mud. IMO you should have a faster time then them.

Yea I know its not a big deal but I just wanted to clarify to the guy who called my claim BS. You dont need to go to such a wide tire-I was only using 275/50-17 on stock XLT wheels and I never had a problem with traction. Going from the 32" tire to the 28" was night and day as you can imagine. That 345 is nice and meaty though and looks nice.

I think people dont realize how a good 60 foot time will help a quarter mile time. All these guys making more power then me and have no traction arn't getting close to the time they should.

I did miss the pictures of his driveshaft and the news about his rear. I do understand the hard work it takes to get a big heavy truck to go fast. What I DON't understand is why the trouble and money to give you the capability of doing something but not using to anywhere near it's potential. STS turbo kit, Modmax crank, Manley rods and pistons, JDM fuel system....... Over $10g's in go-fast just to go 13.49 w/ 468rwhp? My train of thought is if you can do all that on an 07, plus all the other stuff he's done, then he should be able to afford a driveshaft u[grade and a stronger rear too. I don't get why the boost hasn't been upped if even just for the sake of seeing what it's capable of.
Just my 2 cents...

Well....the reason I haven't is things keep breaking and I'm not a millionaire. I have a new heavy duty steel drive shaft in it now, but my pinion bearing in my rearend went out, so now I'm waiting to get that fixed. When I demolished my old drive shaft it burned out my stall and the pump in my tranny, so I had to have that fixed. My turbo is maxed out at 12 1/2 pounds of boost, so I would need a bigger one to get any more HP and thats a pretty penny. I've been pretty busy this summer. My troyer electric fans have been sitting in my bedroom for 3 months now. And the tune on the truck is extremely conservative....because I don't want anything else to break lol. Everyone has a limit to how much the will dump in their money pit.
