We had a dyno day in Waco this past saturday. There was a post about it in the local in regional events forum for about the last month or so. Not trying to knock you by no means, but I fairly positive you dont have everything I do. When I stuff some more air in the motor, I think the numbers will be totally different...or thats atleast what Texas Hardcore tells me!

I also have some still photos of the dyno run in my gallery if anyone is interested.

Texasblake, I dynoed in Utah and live in Colorado. The dyno was at 4400 elavation and I live at 4600 elevation. Im trying to figure out why im not geting more power just like you are. I will get more power soon,just like you will when you start asking questions.
Can you say "BOMBing" its an addiction

The HTT stage III is a great setup. I'm running it with a 12cm non-gated housing. I added the stage III & pods at the same time and got an 84 rwhp gain without touching the pump. I was told that the PODS alone should add about 55 rwhp. I'm sure that the 12cm is cutting my top end hp (I put down 313/749 at the VADTR rally last month ...... but I still have plenty of fuel left to play with). The 16cm would no doubt be the better choice to make good hp, but I like the 12cm as far as daily driving is concerned (have to be careful on wet roads ) The only drawback (not for me) is the whistle from the turbo ...... LOUD ... VERY LOUD. My daughter covers her ears at anything at about 10psi and above.

Calvin-
Thanks for the info on the HTT setup. I've been eyeing it as a possible upgrade if the POD's I plan to install make things too toasty. I'm glad to hear it works well with the 12 cm, I really don't want to lose spool-up. HTT seems to discourage that combination for some reason.

Have you thought about running a wastegated 12 for better top end? You can usually get 'em pretty cheap or free.

Cool. That's what I figured. Some of my 4x4 buddies went to the dyno. Too bad my truck is in the paintshop, I was cruising through Waco this weekend on the way to Dallas in a friend's truck. We should have stopped by.

JMO, but the 12cm and even the 14cm is too small for what you are wanting to do... In fact my 16cm is too small as well, albeit at the very upper end only.
If you do not 'gate the smaller housings you'll have nightmare'ish EGT's...trust me
At the very least run a ported 16cm, including porting your stock exhaust manifold.. just be carefull when you do the porting, you don't want to reduce exhaust gas velocity, just smooth out the flow.

As an aside, I ran a modified HX50/15 on my truck last year... I also had hog nozzles WAY bigger than the POD injectors...
My dyno numbers were 374.9 HP, 1800*F PEGGED, 55 psi boost.
The results were basically a surprise to see ..... the turbo was too big to spool under 2000RPM, and the EGT's got a head start on the turbo so bad that the EGT's were not controllable since I could not stay in it long enough to bring them down.
Now, on the highway, it was another thing altogether.... once I was at, say, 60 MPH and I stepped on it.... well, all I can say is holy mary mother of gord....it was very similar to strapping an SRB to the back and lighting it....WILD RIDE !!!!
