Anyone running Indy Specialty turbo weights in a dragon 700?

TRIPLESWILLNEVERDIE! · Dec 2, 2018

So I have a pump gas Silber dragon 700 5#@4-6000ft. that I am tinkering with. Currently running rooster weights at 71 grams gold epi spring 190/335 and engaging at 4400 rpm.
I had the slp green/pink 160/340 and was engaging at only 3300rpm. had a bad dead spot/bog engaging that low so I figured throw the big gold epi spring in and it helped a lot but I'm still wanting more. I'm wondering if the rooster weights aren't too heavy at the heel for the d7 and considering going to the Indy specialy weights.
Just trying to get a more responsive bottom end when I whack the throttle open from idle.

You are leaving a lot of gray area for us to guess at.
Gearing
Track
Secondary setup helix and spring
Belt choice
Belt deflection
Have you checked your engine mounts? The Dragons had a tendency of breaking engine mount straps.

19/42
155
team46 black/orange
1122 belt
all good

Trying to round up a 40/48 at the moment
I'm really thinking those weights are where I can make some gains but would really like some input from someone who has ran the Indy Specialty Turbo weights before I spend the money.
Also have the attitude box green turned all the way down at elevation 14 to1 afr idle cruising but may try to lean down a tad more with fuel pressure. Currently 38psi I really hate to go much leaner but the more fuel I pull the more responsive it gets.

If you purchase the weights you really should purchase the entire kit, it all goes hand in hand. If you just buy the weights, I don't think you will be very successful.

Also you could definitely gear it down further. Need to be in the 2.32 range if not lower for a 700.

Yes I most likely buy the complete kit I was just hoping to get some feedback from someone who has acutally had some experience with those weights or one of thier kits. If I hear a bunch of people saying the Indy turbo weights are overrated or thier setups don't work well then I won't waste the money.

I have a Dragon 700 Boondocker turbo. 7-10 psi depending on elevation.
19/41 gears with 7 tooth 3.0 pitch drivers turning a 174 2.5 CE. 3000-6000 feet.
I'm 170 lbs

I'm not running indy spec weights.
But lightning weights. 75 gr lightened in the heel to 72gr.
Slp blue yellow 140-310 primary engages at 4100.
140-200 sec spring with 44-36 helix.

I've also ran a 44-48 .36 helix with a 180-280 spring
This setup runs less rpm with the same weight and boost than the 44-36 full progressive helix 140-200 spring

I think both directions work pretty good.
The light heel, heavy tip lightning weight is the best part.

Thank you for your input. 44-36 helix sounds backwards for a turbo setup but I guess whatever works.
I like the idea of a weight with a lighter heal like you are running.

There are two schools of thought.
This was originally posted by TRS
Higher spring rates will hold RPM in return limits upshift. Limiting upshift increases RPM and limits track speed. I am running a 140-220 secondary spring in my turbo with 74.6g weights 165-310 primary and it has long legs. Works boondocking, hill climbing, on the trail. 8-9# boost at 8-10,000'. In my stock Pro I am running a 100-150 secondary spring 59g weights with a 110-290 primary. Same helix in both, 46-32F- 46-34F.

This might be from the AAEN book. Not sure
Smaller angles are going to give better backshift and increased belt tension on shift out. Increases rpms, so heavier weights would have to be used.
*-Larger angles are going to give better upshift and reduced belt tension on shift out. Pulls down rpm, so lighter weights would have to be used
