Yah she is gonna rip hard, by my boost calculations at 18 lbs she will make 306 hp. I ordered another strap as well but 2 straps, I agree, is the way to go. It's gonna be a fun year.

So how big is the dude this year after loosing 40lbs? Just curious how much torque you were tossing around last year to rip the strap...

Hillclimber,

I'm ~165 geared up... My limiter broke.

Timbersled/Allen was great and sent me 2 straps.

Mine was attached at the center too, not the side.


Get 2, and then you don't have to worry about it..IMO.

Mine wore/broke right through one of the bolt holes.

lmao Hillclimber, don't you know its not the size that matters but how you put it to work. If you must know I am a paltry 330lb on my way to 260 (it's all muscle bro). My size had nothing to do with the limiter strap giving way though I just had everything a little to tight. I was running about 230-240 hp last year at 12lbs of boost.

hmm is that how much hp i should be claiming @ 12 lbs?

I just say ~200 @ 10k+ and leave it at that.. haha
When your on the hill pullin the trigger it really doesn't matter anyway!!

lol hey i need that spreadsheet?


so thats calculating 232 HP @ 12 lbs at 4,000 ft?

so at 10,000 ft... <whats the % drop per ft with force fed intake?>

~1% / 1000 ft
so, 6% drop from 4k to 10k
232 - 6% (13.92) = 218 HP @ 10k ft

232 - 4% (9.28) = 223 HP @ 8k ft
232 - 8% (18.56) = 214 HP @ 12k ft

reversed, for sea level
so, 4% increase from 4k to 0k
232 + 4% (9.28) = 241 HP @ 0k ft (sea level)


And for a NA sled at a claimed 160 HP (800 big bore lets say), at 3% drop per 1000 ft.

160 - 36% (57.6) = 103 @ 12k ft
160 - 30% (48) = 112 @ 10k ft
160 - 24% (38.4) = 122 @ 8k ft

number games r fun!

According to this calculation method at 10,000ft at 12lbs it would be 204 hp. Dude you need to move down the mountain.
