[sgtmcboom]

143mph
1989 N/A supra
3AM highway

Tires 225 55 16

My friend was on his new bike and wanted to know how fast his bike would go he got up to 133 and then I blew by him at 143 to see what the supra would do.

Neat.

What Speed tracking Navigation unit were you using to measure your MPH as you flew past your friends motorcycle?

Another magic N/a is exactly what I was thinking.

haha, 143, yeah right. I think the factory quoted 133 with a w58. Does anyone know the top speed of an auto n/a?

:bsflag:

My stock 89 Turbo with a shimmed wastegate topped out at that speed on the speedo, no way in hell you're doing it in an N/A with less power.

I coudln't get my Dad's Cressida over an indicated 127.

 

[kabanimk3supra]

I went 198 MPH in my supra, I promise:sarcasm:

 

[queenskid926]

the med 140's seem really high for a n.a, granted i had my red hardtop n/a at an indictaed 137 but it was a hardtop, cloth no power seat, gutted out interior from behind the front seats, k&n fipk intake, short ram intake mod, pacesetter headers to full 3" exhaust no cast, bored out stock throttle body, mild ported head, 1piece aluminum driveshaft, and lastly 1/4 tank of gas,

and that was all she had i was on 17/255/40 tires.

ps. my cousin did all of those n.a mods to the car when he had it, when i got it, i did a simple 7mgte swap and exhaust and it pull harder than when it was n.a, so unless u got a fully worked n.a im calling bullshyt 2

 

[queenskid926]

unless u got some spray lol

 

[SideWinderGX]

I went either 141 or 143 in my Supra with a passenger, was using my TomTom because my speedo was broken at the time

Not sure if I had a boost controller then, I can't remember.

I'd like to go for another run but my mom stole my TomTom :X

 

[Poodles]

Buy another one, they're cheap

 

[suprahero]

We all know his car didn't go 143mph being an NA, but we don't know that his speedometer didn't show that he was going that fast. I'm sure he believes he was going that fast, but we know it's not possible with a stock NA. I think IJ has proven this a few times already.

 

[Frankenstien]

So is there a calculator out there for this type of thing because I know my speedo is inaccurate, but I don't know by how much. Or is there an equasion I can just put the number into?

 

[suprahero]

yeah, there's a calculator somewhere. You can probably google it to find it. I used to have it saved, but now I can't find it.

Here it is.

I don't remember what the final drive is on the five speed or automatic. You'll need to know that to make it accurate.

 

[OkieRA29]

I buried the needle on my first 77 celica many times. I don't think it was fast, but in that car it felt pretty scary!!!

 

[earlingy]

120 stock NA at around 5-5.5k RPM on stock tire size. Car felt just the same as when I was doing 70, very stable, just more wind noise, targa was out.

ditto, cept I have a solid roof. Fastest I've ever driven. It might have squeezed out a little more but I was running out of road and didn't want to hurt edward. Does the supra have a speed limiter?
been in my dad's BMW 5-series at like 145, air conditioning on, baby brother asleep in the back, music at regular volume. Love those germans and their autobahn.
My 240SX is limited at 115, haven't had my current SOHC one that fast, but my last one was DOHC engine and I had it there.

baby brother? you serious? if he is in fact a small child that deserves an ass beating. Germans might have built it, but American owners have to maintain it....

I was wondering the same thing...I wouldn't have done that with someone young in the car.
