Attention: TDR Forum Junkies At Cummins Truck Fest at Bandimere Speedway (5800 ft) in Denver on Sunday I finally got the truck into the thirteens. 
After my first run of the day (13. 83) you could'nt wipe the smile off my face.
It was 91* when I ran the 13. 68. We got rained out so I still had at least two more runs left. The temperture dropped about 20* so I hoped the rain would subside and we could continue. Oh well.
The changes I made from my previous best of 14. 26 @ 95 are as follows;
I changed my clutch from the Luk Ceramettalic to a South Bend 13" FE. There is no comparison! I added approx. 70 more flywheel hp and this clutch did not slip a bit! I launched harder and made a total of 9 runs over the weekend. I was told by spectators that on my last run (I accidentally let the clutch out too fast) that the truck "left the ground". Getrags are good.
Thank you Peter. Now how about a stronger single disk yet?
I changed my injectors from PDR POD's to bigger Dyno-Mite Diesel Performance #4. I highly recommend either injector. The # 4s are cleaner at idle, make a little more hp (25?) and of course are more expensive. Both idle smooth and reduce the engine noise from stockers. Thank you Lenny.
Changed the turbo from a PDR HX 35/16 to a HTT HTB2 62/14. Spools the same at the bottom end but midrange - top end is way faster. Cooler at the top end also. I added the injectors before the turbo change and I picked about 2 psi (max 39) After the new turbo; 37 psi. I estimate I picked up another 25? hp. Thank you Paul and Brandon.
Removed Banks exhaust and added a Rip Rook complete 4" downpipe and exhaust with a muffler. It is as quiet as my Banks,which is what I wanted. I estimate another 10? hp. Thank you Rip.
I also turned the fuel screw in all the way (only 1/8 turn was left) another 5 -10? hp.
Added a K & N filter to be used only at the track. Before turbo change the HX 35 would never suck in filter minder more than 10%. After, it sucked it in halfway.
Last but not least, Thank you Brian (KTA Cummins on the Diesel-Central website) for answering my questions through e-mails. I got some ideas in my head ater talking to you and it was then I decided I needed bigger injectors and a way to get more air.
I will now be forced to install my governor spring that I've had laying around for 2 years since I de-fuel around 103 mph. Maybe I'll even try a KTA Special pump head. Hello HTT, could you convert this to a Sled Puller 66 please?
I apoligize for being long but I just wanted to answer the questions I was asked a lot over the weekend. Many were surprised the engine looked much like their stockers. It's nothing fancy, and I keep no secrets, but the combo works good so far. Estimated 385 Denver rear wheel hp.

. That htb2 will really come alive with a 366 spring, and even more with a kta rotorhead. Great work!
