I decided to go home to LA for Thanksgiving on Thursday afternoon instead of later that night. I just wanted to go home to see the parents, we don't really celebrate the holidays.

Anyways, I was watch "Lexus IS 350 Test Drive" on Speed today in the afternoon since I Tivo'ed last night. They drove the IS on Ojai, 33. Then I realized that I haven't taken my car to the track or canyons for months since I'm all about motorcyles now. The weather was perfect. So I showed, changed, packed, aired my tires, set my suspension, and set off.

Decided to take 166-33-101-10 freeway. 166 is a fast canyon with long sweepers. Just my luck, I get stuck behind a C5 corvette. Of course, he doesn't want to let me pass and we play the cat and mouse game. He pulls away on the straight, i catch him on the turns. I finally get by him when he realized that he wasn't going to out run me on the turns(100-115mph).

I kept doing what I was doing. So now I was going about 115-120 when a turn came up. I down shifted into 4th gear at about 115 mph . I forgot that this was a civic, not a 01 Honda F4i or 05 Kawi 636. The tach went all the way to 6 o'clock, so I'm guessing thats about 11-12k rpm.

The engine died. Luckily, I was able to stop right in front of a gate entrance to a mansion. I didn't hear anything rattling in the engine the whole time. There was no oil leak. So I doubt anything broke. I left the car up on the canyons, doubt it'll get jacked. If so, I got full coverage and will report it stolen. Didnt' want to get raped by the tow truck for getting a tow service on Thankgiving.

Going to figure out how and where to tow it to tomorrow. What a day. My friend picked me up, went over to his place for turkey. Rode his bike by home in the dark with a tinted visor on his helmet. So I rode 20 miles with the visor up. Yes, I felt very refreshed with all the cold air on the face at 75 mph on the way home.

Sorry mom and dad, maybe Christmas.

sux man...i've only seen few cars hit 12k rpms without a problem...like my homies DC2 type R with a spoon built swap it goes up to 15k rpms and has 450 hp... all natural....anyways good luck with the holidays man

Yoshiemaster

so WHO WON?..... ahaha we all know you're the better driver. hope the cars ok.

whoa.... 12k on a d17 motor? You will prpbably need new valve springs, and if you're lucky that's it. Surely you floated the valves, but hopefully it didn't hit the piston, I'm not sure how much clearance Honda gives on the D17's for that. Hope all is well

hehehe tell me how to get my engine revving to 12k

Yoshiemaster

downshitft into 4th at about 115mph

Jrfish007

iTrader: (3)

your d17? You spend more on the engine than you probably spent on you car. My father law is a machinest and has a Camaro with a 350 that goes to 10,000 RPMs.... he said the work he put into that car was equvilant to $15,000 in just machine work, but cost him only material costs.

naw that send u up to about 7000 rpms...downshift to second at 115 and u got yourself 12k rpms cuz of the rev limiter

Yoshiemaster

well according to usafstud...
so whatever, i still wouldn't do it. could u downshift into 2nd at that speed? or would it make that "AHHHH IT'S KILLING MY EARS GRINDING SOUND"

Jrfish007

iTrader: (3)

No, first gear is the only one that has a lockout, well reverse too. 12k is about what a few other have hit while going 90-110 and mis shifting into 2nd gear, so I would say it was 2nd gear.

Yoshiemaster

ahhh, thanks for clearin that up for me.

ncirom2003

iTrader: (7)

rev limiter didnt kick in?, also speed limiter didnt kick in?
mine limited to 7k rpm and 115mph.

ncirom2003

iTrader: (7)

oh just read it only limits revs in first. nvm.

dang, you were trying to run a corvette in your civic? wtf? at 115 in 5th would be at 5.5k rpms. you if her downshifted then i believe he would have went up to at least 9k. i would say 9. if its possible 12 seems a little too high. you at least burned your clutch. i know that much. check your headgasket, or get it checked. im gonna put my money on the valve hitting the poston. tell us how it goes, good luck.

In order for the RPM's to almost double that means the gear ratio of 5 gear would almost have to be double that of fourth, and it's not even close, if you're at 5.5k in 5th and go down to 4th, you'll jump to 7-7.5k. YOur RPM has a linear reasponse to your gear ratio, take look at the gear ratio's HERE

You'll notice that going form 5th gear to 2nd gear you go from 0.757 to 1.870 (for an EX anywya). That is almost double the gearing, hence the RPM's will almost double when going from 5th gear to 2nd gear. To hit 12k RPM, he had to of missed 4th and hit 2nd gear.

Yoshiemaster

i bet theres a guy on a corvette forum sayin he "pwned" a civic.

Sick Cycle

werd ... you misshifted into 2nd.

115 at 4th gear wouldn't be more than 7500 rpms

thegent

Uhm. no.

4th at 190km/h is around 9000rpm bud.

usafstud

iTrader: (2)

i don't think it was second gear

rpm wise, the needle was straight down at the 6 o'clock position

Jrfish007

iTrader: (3)

On an EX,

4th gear = 0.979
5th gear = 0.750

If we assume you are in 5th gear at 5,500 RPM's, you can find the RPM if you shift to 4th. It looks like this,

0.979_____ X
------ = -------
0.750 5,500

it's a simple linear relationship, yes it goes through a final gear, but since both go through the final gear it cancles out. So if you solve for X, you come up with 7,179 RPM. If you shifted to 4th under the same conditions and hit say 9000 RPM, then your 4gear ratio would be:

X______9,000
------ = --------
0.750 5,500

Agian solving for X you get a 4th gear of 1.227 (which is actually close to your 3rd gear).

So lets assume you have a 4th gear of 1.227, when shift at 3,000 RPMS in 4th gear to fifth, that would put you at:

1.227 3,000
------ = --------
0.750 ____ X

X=1833. So that means when you shift from 4th to 5th at 3000 RPM's you drop down to 1850 RPM's? Not in my car...

Sick Cycle

thegent: try again.

usaf: oh yeah .. I was thinking about the rsx tachs ;P

Jrfish007

iTrader: (3)

Well, you may not of hit second gear, the problem is that tach's are extremely inaccurate. And the higher the RPM's the more inaccurate they become, so it is rather hard to tell what RPM you where in.

NoSpleeny

iTrader: (3)

no way... 4th gear at 190 will not go 9000... i want some crack too

man thats crazy...thats what friends are for

Yoshiemaster

when i first saw the title i though u hit a turkey or sumtin.

down_

*puts head down and rais's hand)

Did that as well.

Head gasket
Manifold gasket
Valve Springs
Valves
Resurfaced Pisotons
and Labor

$1,230.94. Price i paid....... $0.00 Thanks to Warrentey

Yoshiemaster

ahahaha, that woulduv been an amazing thread.

AlienX

iTrader: (2)

dude, u might as well had thrown in a new EX motor for less then that...

nindoo

iTrader: (1)

Did you have to force it into the lower gear or the stick just slipped in with ease?

iTrader: (2)

it went right in
