Cassie barely takes an MR2

[CassiesMan]

I dont have very many kills that I brag about, but every now and then one comes along that I can talk about. Tonight was one of those kills.

I was cruisin through Columbia, looking for a good run, but Buisness 70 was just empty as hell. But, on my final way back, I finally got a taker. A nice red, early 90s MR2. At our first light, I wanted to let him know he had a willing runner if he was up, so I gave it a little extra gas off the line. He holds next to me the entire time, and we make the next light right as it turns red. He revs at the light a few times, and I just nod. I've learned the hardway not to rev my car.

Light goes green, and we both punch it. From the line, he instantly gets out a bit, his nose pulling out, and my nose holding right at his door seam. We stay this way through second, when I start pulling. By mid third, I have a nose on him, and we hold this all the way through thrid. I jump into fourth, and get about another foot or so on him, and I'm doing about 85. Its at that point he shuts down, and I do to. We give each other the thumbs up, and he goes to turn, I got a green light.

Normally, with most of my kills being against stock Civics and Neons and other less than impressive (no insults intended), kills like these against cars that can perform (or kinda perform), make me feel good. It was a good race, and he was a good racer. I was even suprised I won. Yay for me.

Cliff Notes: None, read, it forms synaptic connections that allow you to remeber stuff.

was he a turbo or no? also not all early 90's MR2 comes with a LSD. if it was a non turbo model, he most likely didn't have one. i think they became more common on the 93 + models.

also how high was he lauching at? by him only taking you out by half car is extremely good on your part. for a turbo MR2 you need to launch at 5 K. that kind of take off with a LSD and nice wide wheels, it usually takes me by a good 1-1.5 lenght right off the bat. when i'm still fighting for traction, he'll pull another car on me. because of this i can never take my friends MR2 from a stop. they can hang with a AWD take off pretty well.

jekyle and hyde will know more about the LSD option thing. but those cars can seriously take off like monsters. and a stock turbo will run a high 14.

if he's talking about columbia mizery then....no its not turbo, and the same guy tried racing me too right after i got my car, his car has 180k miles on it and a slipping clutch right now (i'm told), bus. loop 70 is where some people go out and cruise up and down racing while the cops watch and wait to pull them over

i'm also told he's looking at a "stage 2 turbo swap"...i think a lot of these people are fulla somethin' brown and gooey

BTW i'll race ur beemer...:-P fo' 20$$

[CassiesMan]

Damn, you in Mizzery too? yeah, thats where I was, Bus 70 in Columbia.

[kittedb18bt]

i was pretty sure that the mr2 turbo ran low 14's stock. beautiful car with the mid engine RWD set up. i still kinda want one especially since we have seen what jekylandhyde has done with his.

[Sleepr awd]

yeah having one would be awesome, but we've confirmed he raced the n/a one
i'd get one just cuz i think it looks really aggressive when lowered on 17 or 18s theres a couple around here like that that are hella sweet

[CivRacer95]

Nice Kill there CassiesMan. I've been blown away by a Few MR2's around here. They are fast. Over course, I drive a Civic, but still they have guts to them. Either, nice kill like I stated earlier. Late...

yea this is true with mr2s, they take off really good. i have a 91 turbo with lsd, and off the line i can hang with my buddies eclipse gsx. same thing with my brothers wrx.

[clawhammer]

Nice kill. Was it turbo or not?

[JekylandHyde]

LSD did not exist on the MR2 until 93. From 93 on it was an option (turbo or NA). If it is a 91 with LSD, it was retrofitted or aftermarket.
Regardless, LSD is the MR2 matters for power-to-the-ground coming out of turns ... not in a straight line. The MR2 stock wil lstill put power down to both wheels.

I have seen turbo MR2s with only basic mods (intake/exhuast .. not even a boost controller) go 13.4 in the 1/4 mile.
The NAs go low 16s ... maybe a high 15 with great driving.
I am sure what you raced was the NA MR2, not a turbo.

Elchicoloco86, no one in the MR2 community talks about mods in "stages" (i.e. stage 2 turbo kit) so I suspect this kid is "fulla somethin' brown and gooey."

The turbo MR2 can launch with the AWD cars ... they are even classed together in Japan for dragracing. It has nothing to do with the LSD, it has to do with the weight distribution. The MR2 is ideally set up for launching.

Which LSD did you install in your car?

i bought the car with the lsd. im not sure what company, or what kind it is, but i know it has one.

i know the engine location is the big reason why it launches so well, i had this thought in my head that everyone was thinking what i was thinking, so i guess i thought everyone would of figured that part out, but isnt lsd suppose to help it launch better than without, no matter what kind it is? cause i was sure that it ll still help it launch better no matter what kind of lsd it was. of course, certain kinds will work better for certain applications, turning, or just straight line.

How do you know?

It is quite possible to launch an MR2 in a straightline an get both wheels to spin without LSD ... even with oversized drag radials. IT is the nature of our differentials. Several people have nailed 1.6 in the 60's drag racing with an MR2 with an open diff. When LSD is added to our cars, it evens out power coming out of turns.

well i did the simple test. i had my rear wheels jacked up, and both wheels would eventually start spinning. i also had it jacked up to one side with a rolling jack, one wheel on the cement, one wheel in the air, and the car moved.

of course its possible to get both tires to spin without lsd, but having an lsd eliminates it from the possibility of having one wheel spin, thats the purpose, either under straight accleration or when acceleration out of turns. could you explain the nature of our diffs?

[1QUICK2]

i need to learn how to launch! before the rebuild my best was like a 2.1. you got any tips hyde. I launched the other day at like 5500 and rode the clutch instead of dropping it. I got instant boost and did not spin the tires at all, it felt really good but i have not been able to do again. but to reply to the post....good kill, but it was probably a non-turbo

Niether of these tests would be proof of having Toyota LSD.
The MR2s LSD is viscous-type LSD.
You cannot identify a viscous-type LSD by turning one wheel and watching the other. When one wheel starts to slip at a great enough rate, the viscous coupling will begin to apply torque to the other wheel. You will NOT generate enough energy rotating one wheel by hand to "energize" the coupling.

And as stated above, the MR2 does put power to both wheels so your rolling jack scenario would work on a non-LSD MR2.

Sure, it's simple. The stock MR2 diff puts power to both wheels.
How's that

The piece of the puzzle you are over looking, is that LSD is a limited slip differential. That means, it onlt does it's jump when there is SLIP! As long as your MR2 is on level ground, launching in a straight line there would be no significant slip. Now, if you are throttling out of a turn and a significant more amount of weight is on one wheel and that one wheel has to travel farther (outside of the turn) then you are going to start slipping a wheel and LSD would be a benefit.

People often confuse LSD and positraction (fixed) axle which always puts equal power to both rear wheels which is not a good thing except for drag racing.

Hope that helps.

2.0-2.1 is a typcial "out of the box" MR2 launch.
With practice 1.8~1.9s should be come common.
