You have to realize that GM just grabs these parts and throws them into an engine without double checking all the clearances- their thought on it is if the first batch of motors is good, the next 10 will be good.. When you B&B an engine, you open up oil clearances, tighten ring gaps, reduce friction, etc, etc... So thats where the extra HP comes in..
On mine, we're having serious tuning issues.. We're running out of fuel above 5000 rpms, but we were still able to make some good power up to that point.. Im still running through the stock cats because I was an idiot and didnt order SW's high flows, so I have a hacked up Y-pipe for now.. On the dyno we ran it through open headers.. i want to say its TonyGXP thats running 12.1's with a 100 shot and converter, not sure though.. My best was a 12.9@106 on the stock tires, I have now doubt if I bolted up some slicks, I could have gone 12.6 or 12.5 If your AFR is 12.5:1 on spray, thats cutting a little lean. we;re sticking to around 11.3-11.5:1 at the most.. Is your truck AWD like mine?? I thought I had pretty good improvements from stock, which was 14.2 @ 107mph. The trucks tune is no where near done and I am sure we will be a little faster next time to the track. I should also have the CAI by the next time we go. Also our AFR was 12.5 on motor, on NOS it was 11.8. Our best sixty foot was 1.69. I would like to see these other trucks that have the same mods as mine in AWD. I am sure the 2wd versions are a lot faster. |
I dunno how well the AWD's will handle a butt load of power.. I hear the SS truck's have had problems going over 450 hp at the crank.. Im not to familiar with the transaxle in these things, but I think they are viscous coupling(?) and I doubt built with tight enough clearances to reduce slippage in high HP applications

The TBSS uses the Torsen T-3 for its AWD transfer case, which is all mechanical and virtually indestructable. You will kill a dozen 4L70E transmissions before you ever break one Torsen T-3.

YOU MEAN 97 mph right no way you ran 107 mph stock |

YOU MEAN 97 mph right no way you ran 107 mph stock Did you ever find out the spring rate on the stock TBSS springs? How about the Belltech 2" TB/Envoy drop springs? I'd like to drop another inch but definitely want to have the same suspension stiffness or stiffer... Did I already mention that every time I see your rig and then look at mine I feel like I'm driving a 4X4? :bang: :lol: |
get the djm 2/4 kit i dont use the belltech set up anymore on teh 2wd trucks. ride starts ok and just gets worse and worse. djm set up you use your stock springs but new upper a arms and strut stops rides much better and handles better

Is that 2" front drop just a 2" over a regular TB (so it would only drop the TBSS 1")?

no that's 2 inches more in front over stock so it would be like a 3 inch drop on a regular trailblazer |

This is what you've done, correct? And what is pictured in your sig? If so, I'm not sure I want to go that low. I'd like another inch, but two is too much for me, which is why I'm looking at springs. Can you be a little more specific and describe exactly what issues you are having with the Belltech springs? Why/how would the ride get worse over time? That doesn't make sense. |
