They were going to but I already had a bung for my wideband gauge that I use with EFI Live. I logged my A/F ratio during the run and it was at 12.0-12.1 @ WOT so I think that is pretty good. Also my timing was at 22 deg @ WOT so I need to do some research if that is to high or to low? I need to talk to Blownchevy or Moregrip about optimal timing with the Radix. When I ran the 12.9 sec 1/4 mile I only had 13 deg @ WOT. I will be giving you a call this winter about the 90mm TB upgrade that you have, Also do you a program worked out for the 6.0L w/Radix? I will be buying an engine soon so I can start building it up so when my 5.3 gets takes a crap I can drop in the newly built 6.0 along with the Radix. Let me know. Thanks, Brad

 

Here is the Dyno Graph

 

Here are some pictures of the damage from the driveshaft breaking. I sent the pictures of the smashed muffler to Corsa in hopes that they will give me a good deal on a new muffler instead of the whole system. As far as the driveshaft is concerned, I am getting one built by Dynotech Engineering in MI. I also have driveshaft loops on order aswell.

 

I can't tell from the pic ( i am pitiful), you a 2 piece? Is that a carrier piece or the actual carnage. Man, sorry to hear you broke the shaft. What gear were you in? rpm?

only 13* for the 12.9? Wowser! You got some room to grow. I'd say. Plenty of research on here for the shaft. I have steel one (3") that I had custom made for my 4l80 swap. It's probably 69" or so. PM me if you want it.

NICE Dyno sheet! Congrats on the numbers.

 

I was in 3rd gear with the convertor unlocked, I was at 5850rpm when the driveshaft broke. Well I did have a 1 piece driveshaft but not anymore of course. I just called up Dynotech Engineering and told them what I had done and gave them all of the correct measurement and they said they will build me a driveshaft that will not break! Yea I didnt check the timing until last night and that is when I noticed what my timing was on the 12.9 run compared to yesterdays dyno run. As soon as I get my truck back together I will head back to the track and see what my truck can do. I am also working on those videos for you, I have one of my truck on the Dyno when it broke the driveshaft. I'll post it on here as soon as I get back tonight. Later.

 

that'd be cool...not that you liked it, but a cool vid nevertheless eh?

 

Here is the video of the Dyno run when the driveshaft breaks, Enjoy.

I ordered my new driveshaft from Dynotech Eng. and they recommended a 4" Steel DOM driveshaft for my truck. They said that the driveshaft is good up to 8000rpm which I think is plenty good. I also called Corsa Performance and they are selling me just a muffler, They had to call Tbyrne to confirm that I bought it and they want me to send back the smashed muffler so they can scrap it. All in All I am very happy with everything so I should have my truck back on the road by Friday.

 

kool!

a 4" steel?! wow, how much does that f-er weigh?

 

I dont know, The guy told me that the steel DOM is what he would buy if he was in my shoes so I will take his word since that is all he does is work with driveshafts. BTW the video is looking good! Later.
