Hi, guys,

I was looking at s2000 in 2001, but ended up getting something else due to the dealer's premium, so basically n00b here
I've heard S2000 is one of the greatest track car, but a little more power would be nice. so my question is if supercharged s2000s would have any issue if it's driven hard for an 1hour (e.g. enduro race) and if supercharger would give significant advantage over NA engined S2k.
I did a search and found it seemed none had a problem, but they are 20-30 min sessions I believe and not really described details about pros/cons.
Any input would be appreciated.

You might get more input from the Forced Induction Forum.


Is this a track only car? What racing series are you going to run?

jonam

It's going to be a track only car. If used on the street, I've learned supercharger is good to go w/o much trouble, but was not able to find a solid confirmation if they would survive intensive track driving.

The car will be brought out of US to participate in a race series in a foreign country. The rule says, max engine size is 2000cc. I see either S2000 or Evo!

i would think a tuned Evo would be more bulletproof than a supercharged S2000, unless you plan to use lower compression pistons, etc... in the S2000.?

How many "tuned Evo"s finished the OTC? Of the 1/6 that finished, how many engines did he go through in 5 days? That's what I thought. They might be "more bulletproof", but someone's firing RPGs at them vs. muskets at the S2K .

Actually, I haven't seen too many people who track their S2000s with superchargers who haven't gone through at least one engine. But that's out of a small sample size.

one thing tho, iirc most of those s2k motors were blown due to oil starvation from lack of baffeld oil pan or dry sump.

jonam

Thanks for the replies guys!
Sounds like supercharger is not the option for open track purpose. but what would be the life span of the supercharged engine assuming 10 race weekends in a year? If it's like every 2nd year, I'd do that..or even every year...
How about NA engine? How many HP can you make out of them with some of the work such as header, exhaust, cams, and so on? I'd like more power but time bomb is no no for me

bluesaint,
Does NA engine suffer from oil starvation? or are you referring the supercharged ones?

mikegarrison

Actually, no one here said that. Apocryphal evidence is that it may not be as reliable as a non-supercharged engine, but that's only apocryphal evidence. Look at a different sample and you may get a different result.
