More than likely these companies do not plan on having bolt-ons like Tube headers and the like when they sell it. More than likely to keep the 50-state legal aspect. They figure this is the one item you will bolt on. It seems llike a good starting point.

I was wondering if you tow anything , and what you noticed if you did.

 

I was wondering the same...i also wonder how much the tranny temps are elevated after a few WOT passes?

 

On rare occasion I tow a boat around, but normally it's just the truck and no trailers.

The trans is actually not too bad after a few runs. Nothing as bas as towing the boat around, but now with the supercharger the temps are likely to rise a bit more. I'll be towing the boat again in about a month from now to get some work done to it and I'll see if I can remember to get some temps for it.

 

Should be at the Baytown track tonight for some test and tune.

We finished up going to the smaller pulley last night, some 55# injectors from a Shelby, and the GM 2Bar cobalt sensor. Last night we just got the tune to where it was drivable and we'll be working on it at the track to get the shift points in the right place and get all the bugs worked out of the tune.

I'll be running it in full street trim with the 22" wheels and at least a half tank of gas or more so I won't be expecting much for stellar times but hope to see a 12 second pass. Last time out it was around a 13.2 with some tune problems and letting out of it slightly. Now with the fresh tune being created at the track and a little more boost it should be running much better.

 

Can't wait to see numbers!

 

nice man! post up some pics and a vid if you can. gona be some nice numbers!

 

60' = 1.911
1/8 = 8.262 @ 85.81
1/4 = 12.896 @ 105.19

Full weight, 1/4 tank of gas, 22" wheels, and running nothing but hot laps to get the tune worked out. Truck runs perfect with a safe 11.7 AFR. It is clear the truck has more left in it, but I am happy with where it sits now as my daily driver and occasional boat mover...

Next time I go out I'll put on the 18" wheels and let the motor cool off for a couple hours before making any passes. I'll also be looking into a stall converter to see about getting it off the line a little better, but I am in no rush for that.

 

Great times!!!

How much boost were you running on that pass? Any idea what kind of power your making?

 

nice numbers, i bet when you start tinkering a bit youll get deep into the 12's!

 

Now were gettin somewhere.Congrats on the new PB.Whats the truck weigh?You puttin any boost in it oe the line or stabbin it?
