Useless Information

[swathdiver]

Rotated and balanced the tires today and replaced the last two TPMS sensors, one of which was on the fritz. These two sensor while identical in look to the other two that were removed earlier, had a different part number. I checked it on ebay and it comes up for Jeeps and Chryslers! So now we know that 56029398AA and 56029398AB will work on our GM trucks.

As usual they could not relearn the tire positions. They were trying to use some shop tool. The old sensors were nearby, there were other GM cars in the bays and the manager's keys for his GMC were on his hip. I took her home, had lunch and came outside and relearned them using the remote. Easy peasy.

12.9 mpg on this tank so far, about 1/3 of a tank to go. Lots of idling and way too much traffic, the Yankees have arrived for winter!

The manager of the tire store has a 2013 version of mine in 2WD and gets 19 mpg @ 80 mph.

The check engine light for that offending cat was on when the tire guys brought the truck out of the bays. I reset it with the Tech2 and away the light and code went, again. Can't ignore it forever but I want to. Ohh, had to nail it to beat the wall of cars coming out of the church parking lot, she spun the tires until traction control kicked in, first time for that but then again I rarely drop the hammer. But looking forward to the drags with it this Friday!

Last tank averaged 13.2 mpg. Was looking at Gas Buddy to see which Mobil station nearby had the best price and noticed that E85 at Racetrac was now $2.079 per gallon. So we took on 22 galleons and headed for the race track. And you know what? My crazy motor averaged 15.6 mpg on the way to the track on E85 and got back up to 13.7 mpg once we got home, about 45 minutes each way averaging 50 mph or so.

Met up with two fellas from the forum here, very nice folks and of course their trucks were faster than mine! We made two passes and then let the transmission cool off for an hour and then made a last pass. The track was not crowded, we could have made a dozen runs if we wanted to. Having never run this thing before, I didn't want to push my luck and leave my transmission or worse all over the track.

First two launches were at 2000 rpms with some wheel spin in 2WD (1st pass with traction control still on, duh!). Those were 16.7s @ 84-85 mph. Dropped the launch rpm to 1500 for the 3rd pass and ran 16.55 @ 85 mph. That's 302 Rear Wheel Horsepower and par for a stock truck. Short times went from 2.7s to 2.526. Once we put sleeves on the tie rods then we'll make some 4WD launches.

More importantly, my wife and children had a wonderful time and cannot wait to return and run the truck down the track themselves! After the fellas left and my 3rd pass complete, I joined my family up in the stands and answered the myriad of questions from my girls with a glad heart. My little ones found my old Grand National t-shirts and wore them tonight!

This is awesome! ​

Nice meeting you and Andy last night...not sure what they(pbir) had planned but was a free for all for the most part
usually they stage 4 lanes for street tire and they other 4 for "no time" and bike/mini drags. and you have time between each run as they rotate classes just to sit in staging lanes, let cool, and bs with drivers.

 

[swathdiver]

The track didn't seem to get organized until that black big rig with the dragster left and then they had the street cars use the left lanes that were blocked by the truck. There were many cars, take that supercharged green caprice for example, that they would have thrown off the track without a cage years ago. Shortly after that a couple of cars broke down at the lights and they had to do a big clean up and then bring out the heat to prep the surface again so we called it a night.

My youngest daughter got up in the stands and someone called her name. It was her classmate who was video taping his Dad's Cadillac. Small world. LS engines seemed to dominate.

It was fun watching your Denali beat those cars too! What do you launch at?

 

[iamdub]

Y no vids? Y'all suck.

 

[randeez]

Vids after its faster

Still messing around with launch in mine it has 3k circle d stall. I'll foot brake it as high as it'll go, but needs a little better tire and/or more power to get thru the weight transfer

 

[swathdiver]

My wife sent me a video of the last pass. Nothing fancy.

 

[swathdiver]

My **** also has videos of the other two trucks and if the drivers OK it, will post to YT and link them here.

 

[randeez]

Go for it

 

[badandyturbo]

By all means. Post it up.

It was nice meeting both of you gentleman. I had a good time. It had been too long since I last went down the track. I am happy with my numbers. My best time was 15.5 @ 91. The truck felt great and temps stayed low.

 

[swathdiver]

That was great! Once you get it weighed we can calculate RWHP, if 5500 and exactly 91 mph through the traps, it made 320 Rear Wheel Horsepower.

Still trying to get those videos from my wife and kids, they're so busy! I haven't seen them either!

 

[swathdiver]

Finally! Took on 20 gallons today of E85 (what percentage of ethanol is anybody's guess!) and last tank of which was burned a quarter mile at a time averaged 12.3 mpg. Drove 120+ miles today and this tank thus far is at 12.4 mpg. Did some spirited driving tonight as the motor was begging to make use of that cool air!

Finally got the other two truck videos from the track last week. My kids are not videographers and I didn't get to teach them that they're supposed to tape the WHOLE run and zoom in on the time at the end in focus! LOL Next time fellas! Without further ado:

Heres from last night, 93 octane. still doesnt launch all that great,Abs/stabilitrac/traction control isnt happy
May try and pull a few fuses before i go back to see if it helps. I think track is shut down untill january tho

I believe you're right about the track's calendar. That's a great short time! If your race weight that night was 5,900 pounds then that time slip shows 455 rear wheel horsepower. I think the only way my rig will get to run like yours is with forced induction!

 

[randeez]

Grab a cheap obd2 bluetooth adapter and torque or dash command to see ethanol

Even with pushing and holding the button it still activates?

 

[swathdiver]

That's a pretty cool display. I can check with the Tech2 but that is after the fact. Don't have a way of knowing what the blend is before pumping.

Yea, push once-traction off. Push and hold for 10sec -stabilitrac and traction off but it won't dig off the line that well. If you watch the video above you really don't hear it start revving until 20-30' out. traction control still lights up on the dash and usually feels like its holding back. 2.0-60' isnt bad by any means for what it is but thats where i'm going to pick up time until i add more power.


and Andys truck is on their facebook page for tonights Truck only event

Andy, your famous!

That's cool! Folks are going to be looking for Andy's truck tonight. Was going to go as well but we have a Christmas Dinner to attend.

My second turbocharged Buick was also a non-intercooled car but with fuel injection. It had an open rear and the best 60' I could get from it on radials was 2.30s. Then I got a posi unit out of an old trans am and my neighbor helped me swap the ring gear and it would short time in the 2.00s the very next time out. Eventually that car would short time in the 1.70s on Sears/Kelly radials before retiring it from racing.

Did you upgrade your brakes? I was having a little trouble holding mine at the line at 2000 rpms. It was probably a lack of familiarity though on my part. In the spring the truck will get leveled and tie rod sleeves then we'll take it back out and do some 4WD launches.
