9R Build - high compression head with twins, billet throttle bodies and injector re-locate

Not at all, this is at 2077 meters (6814 feet) on a stock boost in a climb vs $67,000 900 boost in a climb at 12,000 feet. Needs to gear down. Will have more track speed. And needs better clutching… lol

Didn't realize it was meters.

Either way trackspeed numbers are still very subjective.

Settled into the climb vs riding a wheelie over a crest.

Probably always safe to assume the guy riding 200 days a year has no clue what real sled performance is.

And he definitely hasn't tried a bunch of different options. (He's using the same clutching as the #1 RMSHA racer)

I think you should probably go show BBA just how confused they are.

Pretty easy to see by the speed on the gauge. 900 Boost in a wheelie vs stock boost in a climb..

And just an FYI, this rider was with a RMSHA rider that day testing, and my set up was faster then that set up even with that sled having a bunch of light weight goodies on it. I wouldn't be saying this is if i didnt have the proof to back it.

If it's better then you will have no trouble putting them side by side.

Show the world.

He doesn't have 350hp. Gearing up his 900 boost is losing track speed. 1-1 shift on a boost is 115kmph track speed. Even in his own video he said that the 900 boost is getting 53mph track speed, which is only 85kmph. Those are poor numbers for the amount spent on a 9R boost. A stock boost will see over 90kmph with just SRP cluthcing.

I'm over 70 mph track speed with my turbo 9r on 7.5 lbs boost and av gas. Solid turbo set up, big turbo lots of air flow.

Haha 350hp!!

Any updates on the injector relocate, pipe and head set ups?

Needs some vids of that bad Larry!

I know, I need to get a go pro. Did some testing today, I keep adding weight and it keeps making more power. Brought rpm down to 8400 from 8650 and picked up more track speed. I'm running 150 300 primary spring, 87.5 grams of weight per arm and a 44 degree helix. She's making some power. Lost a little response with all the arm weight, might run a lighter spring so I can pull some weight. Cranking her up to 10 psi tomorrow. This solid kit on 7 is like a silber on 10 or 12. This Zona rotor turbo I'm running is a beast.

I’m running an 850 with injector relocate, YST pipe and modified SLP head. Waiting on a couple different compression ratio Upshift domes to try. Our elevation is 3800-4500 feet. The map is a bit rich for our elevation but with out an AFR you would never know. Runs very clean with no hiccups. I would say out of all the set ups and maps we’ve tried this set up ran flawless and clean from the start.
