This came up on another titan thread on this forum. The titan either has a 2.75 gear or a 3.36 gear with the towing package. Most run 15.4s-15.3 @90mph in the real world. We are getting a lot of baseline timeslips being posted so it's pretty accurate. I have seen some as slow as 16.0 for higher altitudes and in rare cases (like me) 15.2s or 15.1s@91mph just by removing the tailgate and spare.

I have cat-back exhaust, Volant CAI, and 29" tall rear tires for the track (stock are 32.5" tall) and I run 14.6s at about 92.5mph pretty consistently. I just put some electric fans on it but the weather lately has been hotter yet I run the same 14.6s. I run 13.7s@97mph with just a 50shot of nitrous. I'm staying at that level for a little while until I can figure out how much it can really take.

The biggest thing we're waiting for is a programmer. Beween the Chevys and the Hemis, it seems that the programmers help out a lot.
