got the engine installed and everything hooked up went to fire the engine up and nothing. it turns over but not fast enough to start. I had mike from B & B corvette come over and pull all the info off of the computer to build a custom tune for the upgrades. so I have to wait till he comes back and installs the program. I also found out that my dash has completly took a crap none of the guages work nor does the DIC. The back lights come on and nothing for guages. I did some reserch and there is a work call on alot of trucks and avalanches for the guage display not working. So hopefully the dealership can get me some answers before I do fire up the engine and not know vital info like oil pressure, votage, and temprature. this sucks
JUST POSTED A VIDEO ON YOU TUBE OF THE BEAST START UP. type 2500 avalanche exhaust in the search to find it please check it out and let me know what you think. I am still waiting on getting the custom tune. so no questions arise that is moisture in the exhast from the storm the last couple of days.
2500 avalanche dual exhaust
the base line dyno was done with 285-70/17 BF GOODRICH MT it pulled down 230 hp 350 torque. goal with the same size tires just BF GOODRICH KM2 mid tires same size. pull down at least 460-470 hp and over 550 torque at the wheels.
Impressive. The most I pulled with mine is 472rwhp and 499ft# of torque and that's blown on nitrous.
Well the truck is up and running great. Next I am goin to put about 1000 breakin miles and call mike to do a complete dyno tune. I already put 110 miles from yesterday to today. stay tuned
well for those that are wanting an update with the BIG BLOCK BEAST. It is running strong. yesterday my tuner came over and we did some data logging and made some adustments to the long trim fuel, mass air flow tables, and timing.not this week but some time next week she will be going on the dyno for PE table adjustment and trying to pull down some BIG numbers all motor. I do have one question. With all the torque this truck has I still can't break the tires loose like I thought it would. Even with the torque mangement taken off it seems odd to me maybe its just not geared well I don't know. I don't plan on putting a stall in it because of the towing I use the truck for. I do plan on changing the diff gears from 3.73 stock to 4.56 in the near future. any advice or coments welcome thanks
thanks Ohio and main one how big of tire is SKI running on his truck? mine are 285-70R17to get back to factory gear ration I need to go to 4.10 but i was told with the tire size I am at now it would be best to go to 4.56 for towing with this being a big block anything over 10 MPG I am happy with.right now in town and highway I see 13 mpg. thats at a 1000 miles on the engine rebuild.
alright the truck is driving great and it is ready for the dyno to finish tuning. right now I a scheduled to go on friday. anyone want to take a guess at what kind of numbers she will pull?my guess is 425 hp and 530 tq at the wheels like everyone else I hope for more but trying to keep my guess conservative so if it does't make as much as I would like I won't be as dissapointed. LOL
I'm guessing about 6mpg around town Can't wait to read the results.
363 hp at the wheels and 449 lbs of torquea bit disapointed with the hp was expecting at least 400 at the wheelswith raylar claiming 525 at the flywheel. but it is what it isas far as torque I am very pleased 400 lbs from 3000 rpm all the way up. I wanted to post the dyno chart but it is more than 600 kb.
