Husqvarna 1988 510 TE horsepower

I want to know , how much horsepower is the year 1988 510 TE ?

Around 50 reindeers ! In HVA sweden they don't talk in horsepower...

The reindeer is more powerful than the horses...

Reindeer male or female ?

...

on out Dynojet dyno my buddies 1986 AC 510 made 35hp on pump gas and 38hp on VP race gas.

so the proper reindeer to horse (power) conversion has been completed folks, yes and right here at the Cafe Husky site, so tell your friends to come one and come all
35 rear wheel horse-power equals 50 reindeer-power, now we nee to do the gender calculation that was questioned by Michel

a female reindeer would make more power because they have bigger JUGS !

Magazine test I have on the 87 510 TE showed 39.3 hp at rear wheel.

sounds about right, lc adding a few ponies.., er, i mean deer...

liquid cooling didn't make more power, it gave them a chance to tune it a little closer and not worry about overheating
the 430 and 500 2strokes saw no increase just better stability when pushed hard, the clearances were kept closer so the power did not fade under a heavy load WFO

There were a lot more changes to the motor than just the LC. Lighter crank, lighter flywheel, lighter short skirt moly coated piston, clyinder changes etc...

87 model LC 510 makes more torque everywhere than the AC model. AC had 30 ft lb max whereas LC makes more than that everywhere and peaks at 36.7. LC makes up to 10 hp more than the AC at midrange but only 1 hp more at peak. Dirt Rider mag test Sept 86 edition.

I find this hard to believe, both the 430 and 500 got lighter pistons seems the same blank but side cutouts added or enlarged. The air cooled 430 has the earlier reed cage. The liquid cooled 430 and I suppose 400 have much larger transfer ports that are divided.
The ports are similar on the 500 air vs liquid not sure if there is a difference in transfer size, there also is the easier to damage exhaust that is most likely a performance boost. Reed cage is the same.

The ring is a bit higher in the water cooled and the replacement ones the air cooled has to use now. More pronounced it seems in the 430,

hard to believe those earlier smaller ports flow as well as the later ones. especially the air cooled 430 which for some reason still had the old 70s reed blocks, compared to the later ones. could be an illusion but the lc pipes look to have more volume.

10 more horsepower seems pretty optimistic, also considering usually lightening a piston is to achieve higher rpm's, to gain 10hp in the mid seems odd torque maybe, but typically you see hp gains on top, not saying it's not possible but the way they went seems more for the top

pipe dimensions have to do with stroke and scavenging, air vs lc would not play into that, but they routed them differently so it would seem an illusion

the 84 500 was known to be a brute, the lc 500 was heavier but from what i hear would run with my 85

the porting increases were being done before the lc change, i think it was just more or less timing
my brother had a Yami 490 that was no slouch on power, it was a YZ with racing in mind, true it was outdated as an 88 ac but had no issues to speak of
i hear the same comparisons on dual vs single shock, it was just headed that way
but i feel they were bold to be more aggressive on the porting without power failure due to heat in hard competition so i do agree with the lc change

510 TE is a four stroke. Not sure why we are talking about two strokes in this thread?
