I am having some trouble getting the dyno sheet scanned and posted so I will just tell you what the end results where, and once I figure out my scanner tonight or tomorrow I will post the actual sheet.
For Jeff Simons sake, and to avoid confusion These numbers where produced at this dyno, on this day, Other numbers may be different and other dynos may bring different numbers as well. Also We (jim@dynotech and Me) decided to keep the fuel settings very rich for saftey sake until I can get it on snow and see what real world tuning brings. From what I learned from Jim and saw there is easily 10 or more Horsepower to be found at each boost level. I just choose to keep it safe for now.
Here is the results and I will get the dyno sheet figured out later to get them up as well
Boost HP a/f
9 lbs 233 9/1
10lbs 241 10/1
12 lbs 253 10/1
13.5 lbs 271 10/1
Then there was one run we did that was around 15 lbs or 16 and it went over 280 hp but we ended that because it was back firing due to to much fuel.
I also was having issues with the electronic boost controller and couldn't get it to hold boost consistinly.
Again I just want to make sure everybody understands I tuned it for safety, trail ride ability, and for questionable New York fuel. I feel that if I bring the A/F ratio up to 12 to 1 there is alot of power to be found. Jeffs claims on HorsePower for this kit are true and everything he and Allen Ulmer told me about this kit did what they said it would do. Once I get more time and more knowledge on this sled and fuel controller I will bring the A/F ration Up and really let her open up.
Thank you Jim @ dynotech for your insight and keeping me from cranking the boost till she popped.
Thank you Allen Ulmer for calling me a thousand times during the session.
Thank You Jeff Simons for making a kit that is easy to install and I will be calling again once it is on the snow to dial her in more.

Why are you running it so rich? Your down 12-15 HP running it that rich. -------Sorry, just went and re-read you wanted to be safe (pig rich). Ya, your leaving a whole lot of HP on the table running 10/1 air/fuel.
I plan on bringing it down once I get comfortable with the sled on the snow. This was just to get everything dialed in. I can't afford to rebuild the motor so baby steps for me right now. I spoke to jeff when I was all done on the dyno and he told me I am about 10 to 15 hp low at the boost settings due to how much fuel is in there. I believe him and you mike. Just being very careful.

Well done Jeff!
aj and jim, extremely good numbers for running it so rich, 10-1 air fuel ratio is way too rich, (i understand you just want to be safe to start with) like mike said, 12-1 is fine, i usually set them up for 11.5 or 11.8-1 if i want it to be SUPER safe. even though it doesn,t seem like much, a half a point makes a huge difference. to give you an idea of how rich it was, your engine could only make peak power at 10200 rpms on jims dyno when it was supposed to make peak power at 10500- 10800, your easily giving up 15 hp, and probably closer to 20 hp. when you decide your ready to lean it down some, you'll be in for even more fun. but like mike said, please be carefull with it, this is more horsepower than most people are used too, our apex turbos really kick some #*$&@, and it will hurt you if you don't drive it with respect. have fun and thanks again for your efforts in proving our money back guarantee claims. jeff
i got the dyno sheets scanned but I can not get them to go up as an attachment, can I email them to somebody and see if you can get them up??
thanks

i am building 2 more brand new 07 apex rtx turn key turbo sleds right now for anyone interested, at this point we could add extra head gaskets if you wanted the higher boost levels for pump gas with alittle extra cost.
brand new 07 apex rtx....
simons cpr frt mount turbo
installation of turbo
fuel controller
installation of fuel controller
supertune clutch kit
installation of clutch kit
total price....14,960.00
addition of 3 stock head gaskets and
heavy duty cly head studs.....750.00 includes all parts and labor
after turbo install is complete it will cost an
extra 300.00 labor if you want extra head gaskets to take apart sled again.
gauge pod with xd-16 a/f guage, water temp and boost guage is 800.00 including parts and labor if installed with original turbo install.
call jeff at simons cpr if interested..1-414-698-6611

How do you route the turbo return, shows a 90 degree in the picture off the valve cover, mine is a straight, that could be the difference?
Thanks,
P.S.
The fuel tank gauge does not work?
P.S.S.
Runs awesome at elevation!!!!

I would suggest getting the 90 and then:
When looking at the turbo itself from the front of the sled, install the 1st 90 (the one from the turbo housing) so that the barb end is pointed at the 1/4" tapped hole on the front of the compressor.
Install the second 90 (valve cover) so that barb is pointing to the letter "G" in the word MAGNESIUM on the valve cover. Cut the length of hose supplied so that it makes a gentle, downward sloping curve.
Install green clamps.
