The ULTIMATE power vs. longevity example is a top fuel engine. 500ci and 8000hp. Sometimes they don't even make it through a 1/4 mile...

Like stated, the right components and proper tuning will do it.

For example, look at all these 4 cylinders out there make tons of power. Shit Tony Palo at T1 race development has an integra(1.8L) making almost 1000whp running 8.90 in the 1/4. It's nothin new these days. Gotta pay to play though.

1000 hp from 1.8L is impressive......but much easier to do with a power adder or two. It's not really an apples to apples comparison. 800cc @240hp comes out to 300hp per liter. That's pretty amazing. For comparison, one site claimed that nascar's make 850hp, they are 5.8L so you have 146hp per liter. No way am I saying that nascar is cutting edge, but for illustration purposes, look at the power difference per given unit of displacement.

you can definetly buy 125cc gp bikes if you got the right connections in aprilia

and you can buy almost the identical hondas off the website but this is only smaller bikes

12,500 euro roughly for the bike
http://world.honda.com/HRC/products/rs125r/index.html

and another 12,500 for the kit to upgrade to the kind of power they put out in the 125 cc class

high horsepower out of small engines is nothin new
ferrari and lamborghini have been building small displacement engines forever and they make a shit ton of power, they rev to the moon to do it
and f/i isnt the only way to get a lot of power out of an small oem engine
ive seen a naturally aspirated 3.0 in a supra that made 1000+ horsepower on pumpgas

Not without a turbo or SC it didn't! And that, my friend, is not naturally aspirated.

It's pretty easy for normal people like us to mod a 1000 CC bike to put out around 210 HP at the rear wheel.
But getting the last few HP out of an engine requires ALOT of cash and R&D.

Big bang engines, titanium engine parts and the worlds best engineers at your disposal will get you a very long way.

We sponsor the danish RR champ, and his Honda Fireblade with TC and 210 RWHP is pretty solid. BUT they pull the engine apart and replace crank bearings and stuff like that 4 times every season. And his bike is considered a top spec privateer Superbike - good enough for WSBK.
Just imagine how much maintenance a factory team has to do on an engine - let alone a MotoGP team.

GP bikes are also down on HP because of the new rule, but eventually they will catch back up to where it was before they introduced these rules.

And they are reved 17k to 22k. I miss the scream of the v10s though.

Actually by regulations, the fuel they run is a lot similar to the gas you get at the pump. It may have some alcohol, methanol, or ethanol in it though. But the fuel they use now is not too different from pump gas.

That may not have been the case 20+years ago, but increased safetly regulation in the sport kind of lead to that though.

I'll give you benefit of the doubt that you are mistaken and not full of shit.
Please, show me. Link it, pm me whatever. I work on a regular basis with one of the best engine builders in the country. The man has proven results on everything from F1 motors, to being NHRA and IHRA bike engine builder of the year, twin turbo Ford GT, handmade intakes, pretty much everything. He cannot come anywhere near that number NA.

I stand by the statement that is impossible.

check the pacific forum so cal thread, i have 40k on mine, and Nos nelson i think just broke 70k on his 1k. and there are several others with over 20k on their bikes.

i agree, all 1k supras are ether big single or TT.
maybe the guy has a NA-T supra?? don't believe everything you hear. or you will end up like this guy.

Wow, that's very reassuring. I have 13k on mine.

V10's, I miss the V12's They'll never bring back the 10's or the 12's. With today's technology those the old engines will put out 1000hp to 1500hp easily
