Miata > S2000
 
Hey guys, just wanted to let you know how potent a 11psi setup can be. The other night I came across a Supercharged ( Vortech SC w/ water IC ) 01 S2000, and he wanted a piece of my miata sandwich. We had about 5 runs or so from 2nd gear to the end of 4th and every time I was about 2 cars ahead of him. This was completely impromtu, he just pulled up beside me downsifted and motioned that he wanted a race....lol. Me and my friend who was driving with me (SR20 S13 w/ a GT2871R @20psi) were just like WTF, and then we all raced...it was really neato.

He said that he ran a 13.4 @ 109 in the 1/4 ( 2.4 60' ), and made 307whp on a dyno. My car was running 11psi on pumpgas, with just a moderately sized GT3271 turbo. This shows you how potent our little cars can be. I might be making 250-260whp and the lightweight aspect of this car just makes that 250 feel so nice:) I hope this post is permitted. :bigtu:

They're always in shock when a Miata passes them by.:D :beer: cheers!
Just a quick question, why did you lower boost on your setup? :confused:

tylerdurden 09-04-2006 07:34 PM

Nice. :D

Snowsurfer03 09-04-2006 07:47 PM

nice kill!!!:bigtu:

You do realize that that is pretty slow for an s2k. A kid I know has an s2k with just a big shot of nos and he runs 13.3 all day. I just though a full vortech set-up would be faster.:ugh2:

S/C S2000's are fairly slow, i guess because they have such high compression...like 11.0:1 or something. however i have seen some T/C S2000's that whooped some ass


not to knock you or anything, Andy..still a very nice takedown

Snowsurfer03 09-05-2006 12:08 AM

I love the fealling of stoping all over a much higher$$$ car.

AndyFloyd-Do you have any pics of your set-up?

Andy would also have to reopen to post twice after they got closed by the owner of M.net himself. Plus he was a stupid dumbass that gave horrible advice that I always made a point of going back in and correcting.

As much as I like s2000s I hate the tourque curve!!! Way to use it towards your advantage!

Yep- I was the same way. Drove my pal's first gen. Looking forward to it after hearing him rage about how quick the car was. :dunno: I kept waiting for the torque.

Nice kill. I thought a supercharger would do something for an s2000, but I guess at 2800lbs, there's still a lot of metal to get moving. Where was the sr20 s13?

bripab007 09-05-2006 10:16 AM

The centrifugal 'chargers in the Comptech and Vortech kits for S2000's only mimics the stock car's power delivery...actually, it even exacerbates the feeling, what with its quadratic boost curve. That's why so many people are clamoring for BRP's S2000 kit with the positive-displacement 'charger's linear curve.

m2cupcar 09-05-2006 10:26 AM

aaaaahhhh- centrifugal. The S2k needs torque... though I got a similar empty feeling from the NC Mx5.

You do realize that it was still running the 1/4 with a mph of 109mph too right? And his time would have been in the 12's with a decent launch..( 2.4 60'). Dont talk to me like I dont know what fast and slow is....:skid:

I run lower boost on pump gas. I dont ever run 15-16psi on anything but race fuel, which is easy to find around here for 5 dollars a gallon in 110.

olderguy 09-05-2006 11:31 AM

Is the race fuel in your area unleaded?

I don't have that problem with water/alky injection.

jcocke 09-05-2006 01:57 PM

Nice kill! Makes me wanna hurry up and finish my project, though I won't be running that big of a turbo. I was just thinking GT2560R, but after reading this, I may have to at least step it up to a Disco Potato!

Sorry to get side tracked, but nice job!

Honda engines were'nt made to provide substantial torque, The can however create Loads of power however they still lack in torque capacity...psssht hondas ultimate sport car , More like overpriced ultimate facy looking,underpowerd piece of poo with good handling, miata still handles better . I've seen turbo miatas on road courses who rape these guys for fun.

RicanmiataRacer 09-05-2006 03:40 PM

You can add a turbo,supercharger and nitrous on a s2k, There will be a large increase in horsepower yes, but for the money spent, but an assortment of other low-budjet turbo heads who built their cars for half the money will still take a nice warm load on ya!

bripab007 09-05-2006 04:10 PM

Hondas can have torque, they just need to not use shitty forced-induction devices like centrifugal superchargers. I don't know why you'd ever want one when you could have something like this for the S2000: http://www.brperformance.com/Merchan...Category_Code=

Braineack 09-05-2006 04:15 PM

I like the dip before the variable timing kicks in

magnamx-5 09-05-2006 11:25 PM

yeah comeon Andy you know you want to spray it's fun who knows you might even ditch your fmic when you see how well it works. BTW it is alot cheaper than a hydra. and easier to install

hustler 09-05-2006 11:43 PM

lightness for the win. The miat is also substantially cheaper, and less likely to be stolen.

bripab007 09-06-2006 12:02 AM

Yeah, I think BRP had tuned that out a while after they made that dyno chart...they may have even lowered the VTEC high-RPM cam onset point as well, from what I recall.

Water injection doesnt make it possible to make 350whp though.;) I need a stabdalone to do that my good friend.

amen. megaquirt for the win. nice kill andy. though i have to admit that if there was a boosted miata sitting next to a boosted s2k and someone said, "grab whichever ya like..." i might jump in the honda and peel away... ;-)

If I ever get to a dyno I'll see what the OEM ECU can or can't do. :rolleyes:
What do you consider the obstacle that only an aftermarket ecu can handle for higher horsepower?
If push comes to shove, I can always hook up the :nxsmile: :D

devin mac 09-06-2006 12:20 PM

my guess would be adequate fuel delivery with reasonable idle. However, that said, i know of a neon guy thatw as making nearly 500 fwhp with a stock ecu and rising rate setup, so taht might not really be a real barrier... andy?

cccpull 09-06-2006 12:40 PM

I'm running RC650cc injectors with a Walbo 255 lph at a constant 80 psi (non- return fuel system, '99) with a decent 900-950 rpm idle.
So that shouldn't be my problem.

bripab007 09-06-2006 12:53 PM

Altering the OEM ECU's fuel injector signals can only get you so much extra headroom, and your control will never be as precise. The timing is of even greater concern, as the more power you're pushing, the more precise and accurate you'll want the timing advance/retard to be.

I agree with you in that if might/will be more precise timing/fuel, butyou can only run so much timing and dump so much fuel into the engiine.

Since I'm running 650's I don't see the need for more fuel headroom.

How do you run 650cc injectors on stock ecu:eek: . I would love to do that.:sadwavey:
Andy comeon you only need fuel spark and compression if you could tune some 400's with the rx7 to run with the pieburg and run some WI your temps should be down and given the 120+ psi of the peiburg. with the extra fuel of the methanol you might be able to make it work plus your effective octane ratting at the higher boost level's almost like what you run with race gas. so you could run you normal 93 and then spray when the IC and fuel effeciencys start to fall of as a supplement.

Not necessarilly stock, OEM ECU clocked for 7800 rpm redline and the old piggyback HKS S-AFR fuel controller that I've had in the car for several years.

Believe me I was going to go with an aftermarket ecu when I installed the RC650's and to my surprise the HKS was able to make them idle.:eek:

That is true, I agree. But its so much easier and safe to not run FP that high. Even though I have got away with it for years and years I need to move onto a system like the Hydra that can make 350whp without even breaking a sweat ( on 110 ) :)

magnamx-5 09-08-2006 12:23 AM

You will be bored with such a safe setup but maybe a little 350 whp on 93 octane boredom is what you realy need that would put you at 5.9-1 lbs/hp Heck you might even beat crashes miata with that. At least you an some others have given me a way to go for awhile i thought i was stuck at 230's and then i read about you and mimi miata or whoever running 300+cc injectors with the rx7. Thanks for going as far as you did with the stock ecu who knows maybe on day i'll see if more can be had on stock ecu. but that will be a ways down the raod are you going to the autocross at papahjhons stadium in a few weeks? I was thinking of going, never been sounds like fun.
