hmm, if you took the speed of a car that ran a mid 13 (roughly 95mph) and used the same calculation for the 107 mph fps. then subtracted it you would have about a 15 foot difference at the end of the quarter mile.

i would try to do it using limits and distance formulas if i didnt already burn myself out on calc this week

 

god please tell me that you are kidding: pistons rods springs? not in a rotary

also nitrous during a shift for " spooling the turbo" means a blown motor

and in your next post you said twin turbo but in this one you say a T-88h

if you are kidding i am sorry, but your post count leads me to think otherwise

 

bf goodrich drag radial launch at abount 4500rpm, power shiff at about 6800rpm and wave to him as you go by him in 3th gear. lol

 

just what the **** are you talking about? you do know that 1. the FD comes stock with a nice LSD, and 2. LSD's *limit* slip between the 2 drive wheels?

 

hmm i knew i forgot something stupid that he said

 

You are a moron.

 

I didn't mean to say faster in the 1/4 mile, I meant quicker to get down the track. Supra owners like the 80mph roll because it allows them to be in the fat part of the power curve, and most importantly they don't loose traction like they would 1-2-3 gear

 

I think we both agree for the moist part. FDs require more attention the other cars.

And for the guys with the LSD one wheel wonder, I have to agree with cloud9, moron

swolbynos: I bet he's serious. We should tell him to replace his piston return springs for more horse power. Also the blinker fuild could use a change. he the type that puts stickers on his car and thinks it decreases drag or gives him horse power.

 

all you need to beat him is a set of better tires. With the BFG drag radials, you should take any fwd car out of the hole and you should be able to stay ahead of him for the rest of the race.

 

105m/h*1hr/60min*1min/60sec*5280ft/mile= 154 ft/sec.

But the other car is moving too. Lets say the other car is doing 100mph

100m/hr*1hr/60min*1min/60sec*5280ft/mile=146ft/min

These numbers are average speeds, and theory based, but 154-146= 8 ft. Which would be a bit less than 1 car length.

 

You all are apparently retarded or live in computer land rather than reality. One second difference at a dragstrip on a 13 sec car is a HUGE margin.

Schools in session:

Try this drive down the road at 100mph when you get to a bridge have someone in the car start a stop watch after one second you are much farther than 8 ft.

Or have someone drive by you at 100mph. They would pass you by more than 8 feet.

The 8 feet is the distance you are INCREASING OVER the other guy at the point you cross the traps. The 154 is the total amount of distance you have accumulated over the entire 1/4 mile.

The first guy was right about the 154 feet, and apparently the only one NOT smoking crack.

The one second difference is relative to a stationary point not a moving point.

Schools out.

Damn for some people that claim to have physics and calculus backgrounds you sure are WRONG BADLY.

 

If you beat a car by one second at the drag strip then he is behind by the distance HIS car travels in 1 second. On a 14 second car (~100mph) that is about 147 feet. Note that in reality it is actually a little less than 147ft because the slower car does not reach 100mph until right at the finish line, but in the final 147 feet I doubt a 14 sec car accelerates very much anyway.

 

i dont think that dude even owns an FD, or any rotary for a matter of fact..

 

Just got this PM from tensecond1320:
"Wtf yeah ur right bout not havin an FD but maybe you should come on down to lexington and get you *** handed to you by my rebuilt 442 big block or maybe ma brother's Yankel! O yeah to any1 who hates big blocks and thinks an rx-7 could beat even one needs to find a tree all of you!"

Calm down, I never said you did not have an FD. The dude above me did. I said you should upgrade your piston return spring for horse power. If you didn't like the blinker fuild change idea the go **** yourself.

You sound like a old fashion dumb V8 more is better type person.

The crap you stated about the LSD, is just wrong, unless your talking about the drug. Oh, wait, you would be wrong about the drug too.

You post count backs me up, and I feel you should not even post on this forum. Get you V8 out of here. By the way, a rotary can be just as fast or faster then you high and allmighty V8. If you dump enough cash into anything you will likely beat someone.

 

Old big blocks are arcahic and slow. They make 8000ft lbs but no HP. I bet my H/C LS1 makes more hp and will run better numbers than your Olds 442 crap and your brothers over rated Yenko and I still get 25mpg. Old school V8 sounds good but bottomline it aint that good by todays standards.

 

Hehe... I wrote the crazy guy (Cameron Hartnett) an email. Told him he's a moron and shouldn't post here anymore. Now, I'll be the FIRST to admit that I know **** about rotaries, but enough to get buy, and I'm learning more everyday. Especially with the gracious help of gurus here. Even I know some of the **** he doesn't. Here's what the idiot wrote back:

Lolz ur right I dont have an FD and yeah im only 13 sorry;p My brother rebuilds 20's not me i got into rebuilds about 2 years ago;p but geuss what i suck at rotaries ur right but you wanna come with ur FD against ma totally rebuilt 442 big block go ahead and come have your *** handed to you. Yeah and a t88-h is a pretty huge turbo it would only be able to fit one unless you totally customized the FD's engine bay. O yeah go find a tree all you FD fans

Maybe HE should go find a tree?? Make a shitload of paper out of it to practice his grammer skills? Or at least get a license before he talks about a car he knows less than me about?

 

Yeah, I am no expert either.

P.S.
Sorry for hijacking this thread. Subject changed a little.

 

Uhm yeah...not gonna argue because I see you as an arguing type just by your condescending, know-it-all tone coming out of nowhere.....but, your still wrong there sweet pee. Reason I know, my other car I ran a 14.93 in, I was going against a 57 Chevy who ran a 13.9...lets just say there wasn't half a ******* football field between us when we crossed the finish line.

 

looks like we all use different math

 

Soi, I'd like to know what your bad *** big block runs in the 1/4, also what fuel does it run. Got a mph? What about a 60 foot?

ok anywayzzzz, back to the topic at hand!! pleazzze! the 2 main things i have realized i need to learn are: 1:how to launch well and
2: when to shift...
what are ur thoughts? please no negative threads here, thanx

 

chris- i have a copy of your dyno sheet, and your hp peaks at around 6k rpm(looks like a boost spike), drops off about 25hp and levels out til around 7200. i'm not sure what your optimal shift points are, but brodies car with his stock ports and twins was around 7000. i think mine was about the same. hopefully some more knowledgable people can chime in with some more info.

you should have got a email from shep today about sunday's auto-x/meet. pm me if you didn't get it.

 

for launching you need to find the spot where you wont lose traction and your car doesnt bog. so find the right rpm with the right engagement speed of the clutch. for shifting you need to shift a few hundred rpm past where your max power is so when you get to the next gear you are in more power again. of course shift as fast as you can thats critical so you dont have to build boost over again. this thread is fucked good luck

 

Anyone who said that a 1 second difference is 1 car length...you guys should be ashamed of yourselves. Think about it...you can run 10 ft in a second. Actually there are people who do over 30 feet a second running and they sure aren't running 100mph.

 

GET STREET SLICKS AND...With a turbo engine, you have to constently rev the motor to keep the boost up. You have to practice to match when the boost is up and when to release the clutch. It is different with NA motors, because all you do is keep it at a constant rpm, with consistent results. However, if you do that with a turbo motor, you will notice the boost will drop to vacuum, but if you keep revving the motor, it will stay near or above at zero, which is better then nothing.
