Top speed

[tritonheat1]

honestly i hate arguing with (brainless boneheads) i just posted a article stat about the Celica GT-S where it did 130mph in 5th gear at (7800rpms)G-ratio 0.92 redlined limiter, and 123mph 6th gear at 5850rpms Ratio 0.73. it all depends what the gear ratio is and if the final drive ratio then your car can achieve it's goal. Boy horsepower has nothing to do with Topspeed for the last time since u people have that computerized already in your head. have a nice day

tritonheat1,

Wow, we're brainless boneheads, OK... This is why I never post on these forums.

Anyway, you are right gear ratios are very important in the top speed. I didn't see anyone on the forums disagree with that.

Gear ratios will determine your horse power at a given speed. Have you ever looked at a dyno plot. Take a look the RPMS versus horsepower plot. Notice that for larger RPMS the horsepower increases until it saturates?

Well, for the Celica GT-S that did 130MPH in 5th gear at 7800RPM and only 123MPH gear at 5850RPMS in 6th gear. Well, take a dyno plot of a Celica GT-S and you will see that the HP at 7800RPM is higher than when the engine is running at 5850RPMS.

Anyway, before you start calling people stupid you should try and understand what they are talking about. Anyway, if your so smart then you'll probably be able to understand this article on HP vs. RPM:

HP vs Torque

Actually this article is better because it also explains how drag comes into it. It's also a lot less technical... However, this article shows that I was off in my previous equations (now I feel stupid, I should've paid attention in class). Anyway, read it if your interested... *edit* removed some stuff that was irrelevant.

Torque, HP, Speed

If you don't read any of the other articles read this one... It seems to be very clear.

Horsepower vs. Torque

he7y guys, just a few things. i used to be into hot rod trucks, and for some reason, the heavier the truck was the higher top speed. 0-60 wasnt as good but top speed was higher by about 5-15 mph. also, i couldnt break 120, but it wasnt broke in yet. anyways, my rpms were pretty high, i dont think the car will do much faster, no matter the drag or hp. rpms limit the car, i think another gear would be great, especially on the highway.

 

[frady2001]

oh yeah forgot, drafting someone WILL give you lots of speed. a budy of mine had a four-wheel drive toyota truck that wouldnt break 80. one night we got some balls and he followed me in my truck . his truck would only do 80 normally, but following me he did about a hundred and ten, however, at 80 his rpms were very low and i had a 79 f-100 so it was a big truck. yes it was very dumb but we were young and dumb. drafting can add lots of speed in some applications, but like i said, our rpms limit our speed

Hey guys i think the topspeed on the Mp3 is only 120-125mph cause when i was on my way home from the bowling alley on the base leaving the gate me and my dad were crusing next to each other with out 2-way nextel cellphones talking i had to do 71-72mph to stay side by side with him and he was only doing 70mph that's probably cause my 17's but anyways i notice behind me a hoodscoop i told my dad on the nextal radio that this mustang was on my a** and i'm gonna take him i dropt 4th did 110mph at 6300rpms hit fifth slowed down to 100mph then he drafted up behind me close went to the next lane i waited till we were side by side then dropt to fourth again and did 115mph at redline hit 5th and his car jumped as my front bumper was by his side front door i glanced in my rear view mirror saw my dad's blue lights on the mustang's a** ass the mustang braked, my dad had to brake i asked him how fast he was going he said 125mph, i told him how did you get to 125mph when me and the mustang were barely at 115mph as i slowed down again to 90mph the mustang wanted to play i said fu** it i went to the right lane let him pass me and told my pap's to take him as they both pass i see a yellow mustang with dual side door air panels on the side at the bottom sticking out. I said no way that that could of been a svt-or roush cause he jumped at 115mph either i thought he had a govener or he fuc** up trying to go to next gear. Anyways i think the Mp3 takes awhile to get to 125mph from 115++++mph.

Top speed on a level road...I've maxed out everytime at 117MPH. It seems like the motor would go more (since it isn't redlined at that point). 117 MPH is the same top speed the major car mag tests got with road test equipment). The car is very solid but is pushing the aero pretty hard at that point. Taping up the fogs and grills might get up to 120MPH. There isn't a limiter on the MP3 since the tires are Z rated (which is the big reason the GM models mentioned earlier in this thread are computer restricted to 113MPH (the speed rating of H rated tires).

I could see a few more MPHs with some horsepower mods...probably taking the wing off would help the aero push.

how many miles do you have on your mp3.

Good point! I have not visited the true top end for a while. I now have over 11,000 miles on the engine and might get a bit more out of it.

I have 19,000 Miles on my MP3, and it gets past 117 with now problem.

 

[tritonheat1]

In my opinion the mp3 can do 120-125mph right now as of topspeed i figure if you take off the rear wing spioler, lower the car for more friction, add cai intake and new sparkplugs the mp3 could do easy 130++mph. but to the people that has gone over 125mph you guys probably have more miles and a cai. that helps alot

 

[Coolhand]

Just to make things interesting on this string, since it seems to have died, I hit 132 tonight... mind you the last 5 mph came on a downhill, so I was actually doing 127 mph before I gained the last 5mph. It was freakin' crazy but felt oh so good!!!

 

[tritonheat1]

Sorry guys i can't get past 121mph i think i still need to break in more miles. I'm at 6000 or more right now. I think i need to get a injen cai or aem cai or weapon-r or whatever intake will help cause to all of you who have gone over 125+mph you guys have cai intakes. Well first i have to get my 2nd oil change i just broke the 6000 mark. 121mph it is so far maybe at 8000 or more i will hit 125+mph.

 

[SPANKEDBYAGIRL]

I have an AEM CAI and I lowered it with Eibach pro springs. My car does 130 on flat road, not drafting on its own power no problem and I only have about 6000 miles with two oil changes. If you guys can only get to 125, get the intake, it must help alot. Lowering probably helped a little too.

I went 190 km on one of the highways here...was racing against a celica...crazy s***...love this car...

 

[jimmy baird]

well i hate to say but i might just have everybody beat , maybe . all i did to my car was take off the silencer connected to the air filter box and zoom zoom , iwas on my way. heading back into houston off of i-10 i pulled on to the hov lane going at about120 staying at about 120-124 for about 10 sec its like it jolted again raising to 132 . i let off because there was all the traffic on the right of me and if someone pulled over to the left me and my mp3 were a gonner.all this was done on stock , ok i remember i had one thing i had offrod nos offroad octane booster which increased my octane to like 100-103 octane. but i dont think that would do too much as to make me go 132mph. all the changes ive done is add different rims 5zigen heifields white . i was at the import expo in houston 2001 and won 1St place for my car i am trying to come up with a bad a** design for my car but need one soon any suggestions would be nice good blessings on gettuing to yalls top speed
