Top Speed Runs resurrected?

[ganma_ca]

So earlier I had been talking with a few peeps about doing top speed runs in the S13's, and most agreed they would be too squirly to handle at those speeds, and I agree with in reason that if you are on a crappy paved road with a lot of bumps and what not and winds and a few other variables that it's true. However some would also believe that since the a CA powered S13 is ever lighter that you could only make it to around 140 without being blown off the road or hitting a bump an flying into a ditch while on-lookers watch you burn alive in your upsidedown car! So aside from that: To those of you who doubted an S13 could handle top speed runs muahahhahahahaaa...... Check this video out at 8:26....... 335 km/h = 208 MPH!!!!!!!!!!!!!!!!!!!!! It can be done! (though in the vid it's using an rb26 to keep that front end down and on a nicely paved track lol...., but even later an sr powered hits 200 again) Thus proving provided the right circumstances a CA powered S13 can hit close to 200mph with out being squirly! http://www.youtube.com/watch?v=yQVxUAlx-ks

I'd like to know what the top speed of the fellow CA'ers on here have reached!? I'm planning on getting the hks SLD R1 and FCD to see how fast you can get these things going. (not in any hurry either because I'm not putting down 1,000 hp lol) TMS, know any numbers from some of the bawler CA's in Japan????

[themadscientist]

I know my CA18DE gutted Silvia would go 190+KPH

I laughed watching that vid. My R32 GTS4 with an RB20DET, RB25 turbo set to .9 kilo, fmic, one know AFC and Apexi multichecker removing the speed cut did 240+KPH

Granted, I doubt it got to that speed as quickly as the cars in this vid who were topping at 250KPH.

My 180 still has a speed cut so it is artificially limited to about 190-ish KPH. Even at what I consider pedestrian speed like that, with that heavy sheet of glass weighing it down, the car gets spooky. I wouldn't try top speed runs without getting the car down on serious suspension, decent front aero to split the air and a nice wing to keep the a** pushed down.

I am not one to wag a finger, I am guiltier than most of it, but please avoid doing this on roads at time where one might endanger others with the attempted suicide. Prep the car with suspension, aerodynamics, brakes, caging, all safety possible. When playing this game, a huge ticket is near the "good" end of the results scale.

I remember on SXOC a while back someone managed about 196mph with a CA18 at the top speed thing.

Lets be honest though, going more than about 140 in an S chassis is dumb as hell. I mean, s*** feels unsafe at 120, its just too small. If I am going to be breaking 150, I want a car with some girth.

So true, it reaches a point where you dont trust the car anymore.It feels as if its going to fall apart any second.

But its fun to try nonetheless.

[ganma_ca]

Well the way I see it is you have bikers that 200 on GSXR 1000's and Haya's so wtf not in a 2fizzle? It weighs a lot more and is safer. But true I'm not talking like some dd stuff. I mean like full roll cage full suspension all the engine mods all safety and what not, and around 3 am on a weekday on a newly paved highway with a Valentine on your side lol. Lets just say I was talking to my buddy Yo who happened to be the only Silvia driver this year in the Gumball 3000! #22 kick @$$ awesomeness, and he got his up to around 175 mph. Something I've always wanted to do. Dai that lucky f@C%er!!!! Hell if we could all be bawler like Chiba Kun/Smokey Nagata and build 1,200 hp Supra's or Skylines and take them past the 200mph mark I'd be all about it. But reaching 200 in what I got is what I have to do and that video proves with the right setup it's sooooo doable!

[ganma_ca]

Oh and TMS that corvette video was EPIC FAIL lol what a tard. First off he did it during the middle of the day that was his first mistake, second he weaved like an idiot, and we all know if you are doing a top speed run and you weave it's about to spell disaster. And thirdly he was running from the police lol so of course you are going to F@%K up and slam your fresh corvette into the back of a slow semi lol

It's very true there are a lot of high risks involved but so are the rewards from the rush involved! It's be pretty pointless to do it at a drag track because in a 1/4 mile my car sure as hell won't hit anything past 108 lol, so I need some room. I am going to see if I could do it down at the track at PPIR (pike peak international raceway) because it is set up nascar style which is perfect for top speed runs. And worst that happens is I pull a Dai blow out a tire and head for a wall lol! But it's something still in the future, it's not going to be happening this year, but maybe next:) What's the fastest anyone on here has gone? (not peeps from other sites or anything)

[r34 gtr]

Well, a liter bike is designed to go fast as hell. A 240sx is not. I am sure when they were designing the R1 and GSXR1000 and the CBR1000RR that they took them up to really, really high speeds. When do you suppose they were lapping Talladega at 195mph in the S-chassis during testing? Yeah I would have to guess never, ever.

200 is a big number, usually reserved for really expensive cars that were designed to go that fast. I wouldn't go trying to break it in something so flimsy as the s13. Seriously, if you want to go 200, just buy a liter bike, its so much cheaper!

[bentvalves]

your underestimating the seriousness of 200mph ganma, and overestimating the 240sx in terms of a good choice for a car to do it in.

unless your BOC and your pockets are full of money like whoa then just forget about it.

[ganma_ca]

Last 2 comments.... A. Yes I am flippin crazy I lost my license going 134 in my 90 7mgte supra(what I had before I bout the 240) speed limiter removed, so I could have gone faster. B. You 2 obviously didn't watch the video. 240's are very aero dynamic. No nissan probably didn't test them up to 200 mph lol. But they are still in fact very aero dynamic. You don't have to be a big bawler to get it up that fast either. (you have to be a bawler to get it up to those speeds fast lmao). I have had my 240 up to at least 110+. The things I need are the SLD/Roll Cage/Tires(z rated)and some aero parts to keep it down. I'm not shooting for 200 I haven't underestimated that number. I'm shooting for 250...... JK I want to do at least 160 and that is plenty safe in an S13. The only thing S13's need really is to have some added weight up front, and not even that because that vid shows a 240 with an SR hitting 200. Not as crazy as you guys are making it out to be! And it did it as solid as ever. I'm sure there was quite a bit of money put into it mainly the engine, and suspension but other then that not much else, the body was stock looking and NONE of them even had wings to keep downforce on the rear tires. So yes next year I fully intend to make a video:) Show you guys some hopefully fun exploits of a CA S13 doing at least 160+ (probably have to show you on a Defi link since my speedo won't show it). I feel very comfortable in the S13 at high speeds, not as much as the supra I had, but that thing also weighed like 3400 lol...

[KEMP]

so what do you guys think the ca with the 4.36 gears would top out at?

[ser20det]

Norris design top speed with the ca18det s13 they have built was 186mph.

As noticed on their website.

http://www.norrisdesigns.com/demo-s13.asp

[ganma_ca]

That's beautiful, very good number to be at. 186 in a CA silvia is awesomeness.Honestly I have no idea what the best rear end to have in the thing would be, not to mention the transmission. I know a guy who was using the S15 6 speed(i don't like them because I think they are kinda fragile). But I'm sure any of the 5 speeds we could use weather it be from a ca/ka should work fine for up to 160+. I'd like to see the suspension set ups on those silvia's in the vid though as I'm sure they are pretty bawler. And crazy through. I was just thinking with a set of teins the edc, tie rods, adjustable camber/toe in out plates should be pretty much set for the suspension. Maybe have to find out what kind of tires they were using, i'd probably be going with some yoko's. w at least to z. Making around 300 horse should probably take me at least 18 to 20 seconds I'm guessing to reach around 170. I wonder what our guys from europe have done? I forgot their names but the big money guys that are making like 600 hp on their ca's...

[r34 gtr]

You should be able to do 178mph at 8000rpm in 5th with the stock 5th gear, and stock rear end.

167mph at 8000rpm with the stock transmission and the 4.36 rear end.

The money maker is the 300Z TT rear end, which would let you do 198mph at 8000rpm with the stock transmission in 5th gear.

That page should keep you entertained.

S13 Drag coefficient is .31Frontal area is 19.59 square feetWeight 2699 lbs without a driver

Also....you are limited by gearing

http://www.apexgarage.com/tech/gear_ratios.shtml

shown here

http://en.wikipedia.org/wiki/Nissan_180SX(which I think has the final drive ratio wrong)

So....with 245/45/r16 tires in back.....7700 rpm....OEM CA Trans

4.60 (nismo/Xterra WD22) = 147mph

4.36 (JDM CA18 VLSD) vlsd = 155mph

4.09 (JDM/USDM KA/SR) open/vlsd = 165mph

3.91 (J30) vlsd = 173mph

3.69 (S14 SR turbo/S15/Q45) h/vlsd = 183mph

3.54 (300zx TT) vlsd = 191mph

[ganma_ca]

Thanks for the info guys, looks like 300zx vlsd is the way to go. I was about to go with one from a J30, but after checking out those specs for the 300z, I think that will be my choice. Thanks for the websites too. Lot of very very useful info on them. Anyone ever run a diff cooler? Not that I intend on running at these speeds for very long amounts of time, but I'm thinking with a viscous maybe a diff cooler isn't such a good idea, but if I went with a kaaz or cusco 2.0 one might be needed??? Thanks

[r34 gtr]

^ Please note that the 300zx TT uses a R230V diff that will NOT fit in a 240sx. Its just the ideal gear ratio for hauling a**. You can swap the ring gear to your R200 though I understand.

Also, mbmb, who the hell pansies out at 7700rpm in a CA18?

OK...scratch the Z32 TT, use an 89-96 Q45 R200 instead.

7700 RPM....isnt that what the factory rev limit is?

[exacyzm]

That S13 with the RB26 hitting 335 km/h was quite impressive. Body looked pretty stock too, no wing or other aero aids.

[BQ.05.TD]

228 in the poosar and it felt like it wanted to go alot further. but ran out of revs

[roplusbee]

I pegged my speedometer inbetween the Odo and Trip meters. My cluster had 260 KPH on it (white faces, damn should have stripped that car). I had CA18DET, full suspension, S14 Turbo (destroyed my stocker twice), 440s, and 3.9 diff. 260 KPH => 160ish MPH and it felt super stable at that speed.

[s13redmon]

haha, did 120-something in 4th the other day... i love highway 11 in northeast sc

[s13redmon]

oh, and for top speed you would be better off with the ka trans than ca, it has a smaller 5th gear ratio, i think its like .76 where the ca is .8 something, don't hold me to the numbers but it makes a difference

[Nunook]

ok what i do is set my turbo timer to show kph, so eventhough my speedo is over I can still tell how fast im going.

The other day I did about 130, but I didnt take it up in the revs cause I needed to change my oil badly. stock transmission, usdm vlsd. I think though from how it looked i would top out at about 145mph. maybe im wrong? been thinking about getting the ka transmission and the j30 diff for a while now, but never have the money. also if i was gonna do that more often I would have to have a rollcage.

other then that the car was stable. its lowered with coilovers, no wing but its got a body kit i pieced together. Also when I hit about 120 everything got a bit quite, as though it was in the sweet spot.

[mydato]

Top speed at Sandown Race Way was 248 Kph / 155mph on the front straight in my Datsun 1600 with CA18DET ran out of straight track to go any quicker.

[r34 gtr]

155 in a little Datsun must have been wild!
