whats the most bhp anyone has seen, had or heard of out of a s2k without supercharger or turbo?? just wondering as iv got a few mods had it dyno'd and it cam up with 283bhp at the flywheel which i didnt think was bad for the few mods iv got.??

 

Trouble is you can't take rolling road/dyno results as gospel. Sounds a bit much to me.

 

283 atf is impossible without MAJOR work, so I would screw it up and put it in the bin unless you ahve had major engine surgery

What mods have you got?

You can add intakes, decat, manifold, full system and a remapped ECU and only get 10-15 bhp peak.

I think i've seen 280 ish with individual throttle bodies and internal work, plus standalone ECU.

 

well i had it dyno before i put the exhaust manifold on and it was 276bhp at the flywheel so im not sure it is quick ran santa pod in 12.8 sec at 104mph but im not sure about the dyno prin outs iv order a bigger throttle body and inlet manifold to port to match the throttle body and im going to get it remapped i just wish i knew the bhp at the wheels

 

With those mods i'd expect 3 bhp more than standard.

A throttle body probably won't do much as it's not really a restriction.

Your 276 bhp is also impossible. Please don't believe a word of it! Unless there is some serious internal mods which happened before you bought it

The S2000 engine is extremely hard to extract any extra power from.

What type of dyno is it?

I'd try a different one (Dyno Dynamics is your best bet)

 

Really? I thought 14 secs was about right for a standard car?

 

Are you American?

 

if you have ran a 12.8 sec qtr mile then i guess the power of 280bhp would be correct as a stock car isnt that quick down the qtr mile.

 

i'm not american and its not stock stated off as a jdm import its got fast flow cat , cat back exhaust 2.75" piping 4-2-1 manifold with 2.25 " to 2.5" at cat custom built ram air throught the airbox with a k'n filter and had a remap but going to get another inlet manifold and a bigger throttle body and match the 2 and then another remap

i wasnt to sure with the dyno results i thought myself they seemd a little high but iv raced a scooby that was 330bhp a corsa turbo that was 350bhp and a tigra 3.0 v6 that was 290bhp and iv been side by side with them all the time so im not sure if the result of 280bhp is correct i'm going to have it done again after the remap.

 

JDM import comes with about 5 bhp more on 97-99 Ron fuel.

When you say "remap" what ECU are you using?

The Honda one can't be remapped currently - it can be piggybacked or replaced though.
