If the S2000 loafed around at ~1500RPM @ 80MPH, it would get better mileage, too. It doesn't mean I'd want to drive it.

Well, the unfortunate thing is that the S2000 wouldn't be able to maintain 80mph at 1500rpm as it wouldn't make enough power. Quite unlike a larger displacement V8 that makes power all over the rev band.

 

True, a while back people were making close to 300 whp with boltons using the MDX 3.5L block and the CL type S heads. It's not DOHC but should still go low to mid 13's in a 6spd CL type S.

 

One of the reasons a C5 or C6 can loaf along at such a low cruising rpm is due to displacement. Build a 4.4L V8 out of two S2k engines, and it stands to reason that it will also produce significantly more torque than an S2000, and could therefore have a more fuel-efficient overdrive gear for freeway cruising without sacrificing passing torque.

BTW Todd, you wouldn't be the first to mate a couple of high revving inline fours into a single V8 - Radical Sports cars has created a 2.6L V8 using two Suzuki Hayabusa engines... 363bhp at 10,300rpm, with 196 ft lbs of torque at 7,000rpm.

 

I'd be satisfied with al little extra torque from n lightweight IMA, and maybe a lean burn on/off switch for 6th gear. Should satisfy the low -end power complaints, and my complaint about 25mpg from a 4cyl (although the prelude got similar gas numbers)

 

ON the topic.... when did Honda do away with tming belts? I was reading about the TSX (K24A) and was surprised to see it had a timing chain instead of belt... I know I have been in Suby land too long, but are all of the newer Honda engines like this?

 

When they switched to mostly i-vtec engines. I don't know specifically if it has to do with the variable cam timing or anything, but whenever you see i-vtec...it's a chain drive! The S2000 is chain driven too no?

 

i-VTEC doesn't really make a chain more difficult. Keep in mind that chains were around long before belts were.

The K17's (current Civic) are belt-driven. The K24 (CR-V, TSX) are chain-driven. I thought the K20's (RSX) were belt, but Ryan can probably speak to that...

Casey, the F20C (S2k) was the first chain-driven Honda that I can remember.

 

Yes, the K20s in the RSX (base, Type-S, EP3 Si, '06 Si) are chain driven.
