Raced an s2000..
 

Last night I raced a s2k with I/H/E. Ended up pulling several car lengths on him, just walked him every race. Now I am starting to wonder what whp I'm at. I was thinking around 190-200.

This was at 10psi on my greddy. Any input?

/ricer thread over. :jerkit:

Well you have to consider the power to weight differences as well as power curves. Im just saying, from what Ive heard at your psi level that sounds about right.

I have handled s2000's and srt4's at 7 psi and a half assed tune.

I had fun CRUSHING American Iron cars, blown Cobras, Formula Firebirds, and my nemesis SS Camaro at Hallett yesterday. Those dude's had to be confused when I steam rolled them on the straights in addition to closing 100-10' on corner entry , lol.

Videos or it never happened

I ran a 1:30.1 yesterday, which is 2-seconds slower than I should be going. That's a front half American Iron (non CMC) qualifying time.

Dan who was fastest yesterday ran a 1:28.

I smoked an s2000 from a roll with a shitty tune on 7psi. I'd guess I was makin 170whp. I can guess hp on a 1.6 with a greddy. Maybe 170 at 10psi? Maybe?

IIRC I read a comparo of the S2K and a MSM a long time back. The (140WHP?) MSM had the S2K covered most of the time, only really loosing ground on longer straights.

S2Ks only make about 155TQ. And that's from 6000 to 8500. It makes a neato HP/L number due to the RPM, but it's just not going to pull hard in a car on the wrong side of 2500LBs. I swear those things would probably be faster with a K20 even if they did not look as cool on paper.

I bet with a 10PSIG Greddy you are at just under 200WHP, and the bolt-ons he had just wont do any good as a result.

S2K with driver is going to weigh in at approx 2950 lbs, your miata weighs in around 2350 pounds with driver. It won't take much to stay with a stock S2K. But don't bash the S2K's engines, they are amazing power plants.

Here is a link of a bone stock F20C engine in my miata, it can be a wicked performer it it is not pulling the extra boat anchor weight of an s2000. my car weighs in at 2420 with me in the car, a hard top and a beefy trailer hitch (fail).

I used to assrape s2k's back when I was on 8psi and a slipping stock clutch.

did you do the FABULOUSSSSSSSSSS wave?

Of course I did, the dude was pretty butt hurt that he got pulled on that hard by a miata.

My car is a pig, ac/ps/pw etc. And a hardtop a turbo kit and tools in the back of my car.

My timing map is also very very conservative, need det phones so I can risk adding timing. For now I'm just going to up the boost for some more powah.

10 psi with the typical bolt on breathing mods and tune should be around 200 whp. That's about what a stock-ish S2000 can do, however you car is around 500 lbs lighter. Destroying S2K's gets easy and old pretty quick.* Next time find a Corvette to pick on. Much harder. ;)

*It should be noted that every once in a while, you'll run across a 500+ whp turbo S2K. Those are very fast.

I outran a S2k with a 125shot, the guy said the car has 320+whp, and I was about a car behind a F4i (600) bike last night from a 20 kick.

Straight line is gay though. :fawk:

What do you have on your miata?

Keeping up with a 600 bike you better have a badass setup otherwise I'm calling bs.

If you go to you tube and look for miata vs honda .. it may be the 3rd or 4th video down, its my red miata vs a new s2000 i was at 186 whp and 160 wtq at 11 psi.. and as you can see the s2000 is behind. then i went up to 215 whp and 198tq and like everyone else here says they are not worth racing any more.

My buddy has a pretty close to stock AP2, intake and exhaust only. HE put down 181 and 140 on a dynojet.

Evo3 16g on 18psi. It's a older bike, and they run mid/high 11's.

Cody Strife can vouch for my Miata being pretty damn fast.

Those #s are only attainable with a built s2k motor right?

nope. they can easily do it on stock motor

depends on how long you want to make them

Eww and in a dynojet too, arent they rated at 240hp (crank) from factory?

In the same way a Miata can easily make 350 on a stock motor?

There's a "stock" s2k all over youtube making 700whp. According to the owner is all about the tune :dunno:

yeah, ok, I believe all of that.

I'll take an S2k with an Endyne NA motor, please.

I never get to race shit anymore. No one messes with me exept Phil who can still whoop my ass....for now.

Very flashy car, good looking and handles pretty well, but it just doesn't have the torque for ANYTHING. It really makes it NOT fun to drive. I have to get above 6k anytime I want to move anywhere.

Do LSx's fit into S2K's? Seems like it'd be a pretty capable platform to put the power down...kind of like a FD but convertible.

There are TONS of them making 350whp with a supercharger at 12psi.
Also lots making mid to upper 400's at fairly low boost with turbo's (10-14psi)
I've seen my fair share of 500whp stock motor ones too. Don't know how long they'd last at that level, but at 400 they hold up for YEARS. I've also seen the 700whp stock motor one that was mentioned earlier.

Their pistons and rods are forged iirc.

The thing with those cars is the head flows VERY well, and the shortblock is fairly stout, so people can easily run 35r's and 40r's and have enough revs to be able to have a decent powerband and a very powerful topend. Boost is usually kept fairly low due to the high compression (11.1 iirc), but they put out NASTY numbers.

Very impressive car with boost.
Damn expensive to do it right compared to a miata though.

That's what the owner claims. I had my bullshit meter out when the thread come out, thus the "stock". Those engines have 11:1 comp IIRC

Oh well I knew about the torque issues but those numbers = limp dick

I am jealous. :|

I just tell him he has an rx8 with VTEC

Limp penius fail

This one is local:

Yep, the pistons are forged with a high silicone content to limit expansion and are iron coated. The weak point that most have found with boost are actually the rod bolts.

Mother of god, i <3 ls1 s2k.

On another note I barely pulled a stage 2 caliber srt4. Kid claims 300whp, not sure how true that is.

I'm probably around 190whp.

do i need to post this again?

he should be somewhere around that. those cars are ugly as sin, but pretty peppy..a few bolt ons + tune really wakes them up.

too bad they're fwd

Yeah, I actually rode in it first and thought he would pull me. Thing torque steers like a bitch, scary fwd car imo.

I need moar boost! The only reason I'm running 10psi is because I need a bigger rad/shrouding(which ill be picking up within a few weeks). Plus I'm just enjoying the car how it is for now, I like to leave more headroom. Next time I turn up the boost it will probably be to 13, and after that to 15/16, then ill be looking for WI.

I hazzz WI for cheap too lol.

They have forged cranks too, another important feature of the engine that most everyone over looks is that is is an over square engine which limits torque forces that the engine experiences. This is also one of the reason they rev to the moon. Most of you guys have seen my build, If you have not, here is the link. https://www.miataturbo.net/build-threads-57/f20c-engine-conversion-42810/. It is an F20C (s2000) powered Miata. I am in the process of putting a turbo charger on it. It is a very exspensive build, to do right. Once it is done I will share all my tuning info and dyno numbers. But 450 ish HP on an elt manifold with a genuine Garrett gt 35 turbo 14 -15 lbs of boost is easily obtainable. The rumor is that this boost level will allow a 100k of durability as well.

I have slayed S2Ks on the motor. They do not like it.

They do handle boost well, and whoever said that the high revs make for more useful power on a large tubro nailed it. Lots of Hondas do this. You loose response down low, but shoot if you can rev to 9K and you start making power at 4500, thats pretty good powerband, and you can get away with some pretty cool gearing too. A 2.2L with high compression will spool a 35R on say a .86 T3 hotside pretty well. Shoot a 2L at 8.5:1 comp can spool a 35R to 10-15 LBS by 4500 if its done even reasonably right.

I dont like those things stock (to much weight, not enough TQ) but with forced induction they do tend to make sense. Sort of like 350Z ironically enough, though they are from completely different philosophies.

In for this ^^ :drool:

Where's Pusha. He raced a Miata with an S2K motor swap. Got beat by a few I think.

https://www.miataturbo.net/picture.p...pictureid=1170

My current spark map, afrs are round 11.8-12.0 in boost.

What do you guys thinK?

My car trapped ~1 mph higher, yet the F20-powered Miata weighed slightly more and wasn't running quite right yet.

Ah okay. It must be running right now. I heard Vtech hauling ass around the track on one of the world challenge srt4's.

Speaking of honda slaying, 00si with a turbo. I saw him shedding tears when i went by.

I skipped hondas and went straight to ls1s with my car....

Lets not knock these cars too hard. You can pick them up under 10k all day long now and they are stupid fast stock on a roadrace course. As soon as they start dropping to the 5k range you will see a lot of miata owners jumping ship.

where are you seeing them for under 10k all day long? maybe an 00-02 with super hight miles, but anything 03+ and with decent (under 80k) is still well above 10. The ap2's are still in the 15's

Uh 5K range? Maybe in another ten years. :loser::jerkit:

^ This! I bought my 2000 ap1 (first year) with 44k on it in February of 2009 for $13,900. (Then sold it 8 months later for $14,500)
