so i may be possibly trading my car for an s2000 here soon. its an 08 model.. but i was wondering, why do the 08s have less hp than some of the previous years?

 

no, all the same hp

 

i was looking on edmunds and the 05 had 240 while the 08 had 237? i know its not a noticeable difference at all but just wanted to know why they would have toned it down at all? and if there are any other areas they may have "toned down".

 

I think the official number is 237 but many just round up to 240.

 

oh okay. well what is the maximum hp/tq #s that these things can achieve? like intake, tp, exhaust, clutch/flywheel, etc.. and tune? can these achieve 250whp? im coming from a 300whp n/a 350z. always loved these cars and now have a chance to trade the z for one.

 

It has to do with how measured. It changed one year as did mpg.

 

Just did exhaust, intake, hi-flow cat, and cams on my buddy's MY05 and he is at 250whp after a tune on an AEM EMS. I think the dyno might have been reading a bit high though.

 

I am around 215-220rwhp with Intake, gernpipe and tune.

The fact you will drop 500# from the Z to the S should more than compensate for the hp difference.

Also, the hp is the same for 04-09. the F20 has shown to be a slightly lower TQ and HP motor than the F22

 

I feel old..

Looking for other sources, but here's this to start... https://www.s2ki.com/s2000/topic/315...ae-hp-ratings/

oh and this http://en.wikipedia.org/wiki/Horsepo...ertified_power

SAE certified power

In 2005, the SAE introduced "SAE Certified Power" with SAE J2723.[21] This test is voluntary and is in itself not a separate engine test code but a certification of either J1349 or J1995 after which the manufacturer is allowed to advertise "Certified to SAE J1349" or "Certified to SAE J1995" depending on which test standard have been followed. To attain certification the test must follow the SAE standard in question, take place in an ISO9000/9002 certified facility and be witnessed by an SAE approved third party.

A few manufacturers such as Honda and Toyota switched to the new ratings immediately, with multi-directional results; the rated output of Cadillac's supercharged Northstar V8 jumped from 440 to 469 hp (330 to 350 kW) under the new tests, while the rating for Toyota's Camry 3.0 L 1MZ-FE V6 fell from 210 to 190 hp (160 to 140 kW). The company's Lexus ES 330 and Camry SE V6 were previously rated at 225 hp (168 kW) but the ES330 dropped to 218 hp (163 kW) while the Camry declined to 210 hp (160 kW). The first engine certified under the new program was the 7.0 L LS7 used in the 2006 Chevrolet Corvette Z06. Certified power rose slightly from 500 to 505 hp (373 to 377 kW).

 

more like 215-220whp....

coming from a Z, you will be dissapointed by the power level.
