New GA all motor K series record

[Vteckidd]

Hmmmm just thinking... is it hard to make 100hp/liter because it is a larger engine... or is it because the engine says "made in the USA"?

TVR, BMW, Aston martin, and a couple others don't seem to have any problems building 100+ hp/liter V8s

I don't see any 100hp/liter domestic 4 bangers...
built Honda engines are making 140hp/liter...
built domestic engines are struggling to reach 100hp/liter...

of course 9 times out of 10 this leads into rambling about drag cars which makes me lol... because those engines are nothing at all like what comes in any domestic car.

so... this RSX makes about 140hp/liter on pump gas with oem castings and geometry, just different internals. I'll bet that never happens with a domestic engine, ever. By the time anyone gets close we'll have come up with something other than internal combustion engines.

i really need to stop making general statments in this forum cause then it gets picked apart to death LOL

You cannot count Rotaries for obvious reasons.

If we are talking ALL MOTOR i know of a few 100hp/liter 5.7L LSJuans, or close to it NA.

My point was Hondas are pretty easy to make 100hp/liter, its nothing special, like i said STOCK hondas come with that hp/liter off the showroom floor. hell the RSX and the old Civic SI were 100hp/liter off the showroom floor. Maybe not 100 WHP , but are we talking BHP or WHP?

But people find the bigger the motor the harder it is to reach 100% VE which is all hp/liter means. Honda CONSISTENTLY operate beyond 100% VE because of VTEC and other restrictions, but there comes a point where no matter how big the motor is, you cannot fill the cylinder or flow the air in is ingesting no matter what size cam, header, intake you have. You reach the threshold of how much air a motor can move pretty much and that grows with the size of the motor.

There comes a point where the displacement will give you TQ, not HP (think diesel engines). Is there a cam on the market or a head porting good enough to really produce 100+% VE out of a 2.6L K Series or more? the answer is no, you will always be limited.

all true... I just wanted to make the point that with a lot of imports the OEM parts or the overall design of the engine is such that you can reach these power levels without serious modification. If you stray from "what can I do with OEM designs"... then we'll be sitting here comparing top fuel to F1 or some stupid shit like that.

regarding the cam / head for a 2.6L K... I think they exist, but a 2.6L is a stroker setup. so in order to reach 100+% VE on the larger Ks you need to abandon the OEM spec... which is probably true for all engines. Anyone can take a platform and throw money at it to see results.
