Need Attitude #s for 700 silber kit

[bboll]

Gentlemen, I know there are probably not many Dragon 700 turbo sleds left out there but....

Looking for the numbers you guys ran on your sleds, fuel pressure as well please.

Here is my story:
2007 Dragon 700 Silber Kit - non intercooled
Silber's clutching: Pink primary, 72g & his helix.
6000-8500' (Island Park)
Running around 8-9 psi
70/30 110/pump mix or a 50/50 Av/pump mix
Fuel pressure at 41 psi

Thanks for you help!

Whats it doing? Turn your fuel pressure down to 38 for one. Your throwing two much weight order some turbo weights from Derek at Attitude. What #'s do you need?

I'm from MN, I know a flatland poser who has to trailer to find snow... This is my first year on a turbo sled and I'm just trying to check EVERYTHING over before we head to IP in a week. I understand that I will need to test and tune it a little at elevation. I'm testing it at 1200 ft here in MN.

MN:
I turned down the wastegate as low as it goes, running 8lbs.
I'm running straight 100LL at low elevation.
I have team adjustable weights but left them at 72 grams, Rpms are close but I keep an eye on them.
I have dual koso egts and just installed a AEM AFR.

I'm working off of the base numbers from silber right now, which say 38-42 psi. So, since I will only get 6 days of riding in IP this year....

Here is my BIG question: how much will I need to change the sled from 1500ft to 6000-8000 feet?

Here is my plan for IP.
Start with. Silber's initial numbers in the box,
fuel pressure at 40 psi,
Silber clutching including 72g in the primary,
Boost at 8-10psi on 70/30% on 91/110 mix or 60/40 on 91/100LL mix.

The sled in MN is running lean in the low to mid range with lower boost levels (2-4psi) according to the AFR (16+) and rich on the AFR when WOT (10-11). The egts hit 1250 in the mid range, pto side slightly hotter than the mag side. I have varying the throttle the entire time. Keep in mind this is running it on a lake so not much for load on the sled.

Plugs look good, maybe a little lean but good. I didn't check the piston wash, not real sure what to look for there anyway.

Thanks, this forum is great and has provided me a lot information on turbo sleds...

Numbers

I ran 10-68 weights in my 700 silber kit @ 8000 ft i dont remember what box numbers i had but they were pretty close to what he has on his site for the dragon i just had tolower the green blue from stock program. Just remember that any time you change your fuel pressure you will have to readjust the green blue. I was running around 10-11lbs
