Getting water to mist doesn't require that strong a pump... but in a car i imagine it wouldn't be the same... have you ever run your water injector to see what the spray looked like and how much pressure it had? and how did you wire it up so that it came on when you needed it? rpm or boost based?
again thank you very mucho!

Yeah i run a snow performance kit my spray p atern is very fine and about7 inches wide, for 8-9 psi i ran abuot 77 psi of line pressure. when i went up to 10 psi i upped the pressure to arounf 85 or so. My dad keeps on telling me we should try a winsheild washer pump, but i dunno how long that would last. Adbradley is in the process of doing a DIY WI when he gets his kit sorted we'll see how well it works. I use a boost pressure switch to groung out my hot electrical feed line when the boost hits 4 psi, and i also have a seperate switch to manual override. In case shit happens, never know. If i can be any more help lemme know. I would love to see these WI systems get cheaper and more mainstream.

BTW us born texans gotta stick together.

no sweat man WOT tunning might be of help on the fittings maybe you can swing some spare fittings on a partial kit cheap through him. I like this guy more every post. He's got some interesting ideas and it seems hes got the courage and free time to see if they work.

You guys should try some aero mods to go with the lower suspensions - my car is completely stable at 130.

juhanis · 02-11-2007, 05:32 AM

my gearing limits me. on my supra i would hit 150 by the time i built 1.7 bar

madsnick · 03-05-2008, 12:46 PM

I really don't mind how fast you could get a miata to go... The reason I say this is because I think it would be alot safer going 150 + in a miata rather than a motorcycle. Four wheels always helps in keeping the balance.

UrbanSoot · 03-05-2008, 12:50 PM

i went up to 120mph or so in miata... i dont like driving faster then that

jayc72 · 03-05-2008, 01:14 PM

Wake the dead.

ray_sir_6 · 03-05-2008, 05:45 PM

I got to 7k rpm in 5th and it was still pulling hard. Around 140+ mph. Wasn't floaty or anything. Rode perfectly.

i'd have to disagree. First a sportbike is designed to go well past 150mph smoothly. Sportbikes have sick brakes that will stop in about half the distance of a miata. Also balance is not a factor here, the faster you go on a bike the more stable it becomes from gyroscopic forces. There's also a good chance you'll be wearing leathers and a helmet, if something did happen hopfully you'd be able to scrub off enough speed to survive, in a miata, no hardtop, shorts and t-shirt i don't think that would go too well.

So if you know your top speed, please post it. I'm trying to see how fast a Miata could go with 200-250 hp.

My miata is capable of something north of 150 MPH. Been in excess of 145 multiple times. Hell it will hit 115 at the end of the 1/4 mile and I am still in 4th out of 6 gears. Rev limit 8500, assuming I could hit the rev limit (which I can't with only 300 RWHP) top speed would be 198 MPH.

You feel stable because of the aerodynamics of a bike, but you really aren't as safe. If you hit something in a car, you're in a shell that provides much more protection regardless of the severity of the crash. If you hit something in a motorcycle, the thing will fall apart immediately and you will either go flying, get hit by another car, have some bone turn to jello(happened to a friend who down'd his bike), or be torn to shreds by the impact of falling to the ground going 150 + mph... I'd rather be in a car (no matter if it's topless or not) because at least I have the reassurance of an airbag, crumple zones, and other safety features that came with my car. At least if you lose control of a car, there's always the chance of being able to correct and not hit anything... as for the bike, well... if you didn't watch that one PINKS, here ya go: http://www.youtube.com/watch?v=bc55j...eature=related. Now he was only going 5-10mph and look what this "experienced bike rider" did, imagine that happening at our benchmark 150+... you would be dead! There is no way I would go that fast on a bike ever, It's absolutely much safer going those speeds on four wheels!

madsnick · 03-05-2008, 06:50 PM

Yet another video to prove my point, you can't tell me that a couple of those dumbasses aren't dead...

No they don't. In the 5 seconds I took to search on the topic before I got bored and distracted, I found the 60-0 distance of a Buell XB12 at 123ft. A good stopping distance for a car is 110ft.

At 150mph on a bike, a road reflector means you are dead. A road reflector at 150mph in a Miata makes a very loud noise. I don't really care which one is more stable (My Miata feels decently stable at an indicated 130); I'd rather be in a car, vs. perched on top of an engine strapped to two wheels and a set of handlebars.

Mach929 · 03-05-2008, 07:54 PM

lol a crumple zone at 150mph, that crumple zone includes your body cavity. my point is either way you hit something at 150 you're fucked, at 150 the bike will have a better chance for accident avoidance.

brake comparison
we can try it do 150 side by side stock cbr brakes vs. stock miata brakes

Efini~FC3S · 03-05-2008, 08:03 PM

It's weird how all of those Moto GP riders survive when they spill at 150+...

SamS · 03-05-2008, 08:22 PM

According to motorcycle consumer news, the shortest 60-0 distance for a current bike is 104.8' for a Triumph Speed Triple, I wouldn't say that's half the distance a Miata would take. The limiting factor is the tiny contact patch that motorcycle tires have not to mention high center of gravity.

With that said, I love the Brembos on my Duc, and I have crashed a motorcycle at 70mph with no injuries other than road rash due to an ill-fitting jacket.

madsnick · 03-05-2008, 08:31 PM

Hmmm... who knows. Maybe it has something to do with the fact that they aren't in a real world driving situation and because they use slicks. The only fear is that rear wheel slipping from under you because of gravel and even then, they are turning so hard that they're maybe a foot or two from the ground... not to mention that they also know how to slide and land on the asphalt. Moto GP riders are trained for this type of stuff and they know the risks they are putting themselves under. I think it may be time for some more videos:

1.) (Pay attention to how they land when they wipe out) http://www.youtube.com/watch?v=y7ewq5J2OWk

2.) (Notice their leathers, especially the back portion, this helps so that there heads don't bend too far back. And look at how quickly they slow down when they slide into the grass and gravel and pads on the walls, their sport was made to keep them safe in case anything went wrong. The only thing they can't help is when the bike starts sliding into them.) http://www.youtube.com/watch?v=yTXiMtch9nQ&NR=1

I swear to god, gravel and dirt slows you down so much... I recall the pits at Airborne school and how on the "lateral drift apparatus" when you fall into gravel at a given speed, you slow down fast and it really feels soft. But dirt! We all know how soft dirt usually is... it's a no brainer. My point being, you can't compare Moto GP to two stock vehicles and how they react in the real world under real circumstances. Motorcycles are not the best choice at high speeds on public roads.

Mach929 · 03-05-2008, 08:32 PM

60-0 has nothing to so with 150-0, the reason a bike's 60-0 isn't all that much better if at all than a car is because you're limit braking to keep the back end on the ground, not much of an issue at 150

also don't take the "half the distance too literally"
