Top speed

[3SBlkStreak]

I've had mine up to 130(and still had room left) and I'm bone stock. I have a 98' SL DOHC

[mgk563]

I had my 94 sl goin 135 in 4th gear on a 2 mile stretch. I havent drove it in 2 months tho becasue it lost my licence for me. or my lead foot lost it for me

[Law_3KGT]

damn i had a long straight away and only got my stock 94 sl up to 125 and that was going down a hill. it doesn't seem like it will go past 120 without a hill though.

You sure you may not be off a tooth on timing? That could very well cause the lack of top end.

I've had my car up to 157 with an extra 700 pounds on the car...only reason I slowed down is cuz I was coming to the end of the road

[xXxRocker5150]

^lol you have a lion, the other guys have coyotes... not a fair comparison!

[Mikelb]

Anyone else here with a SOHC? I'd like to see what the highest possible speed on one of them is....

[youngvr4]

so the sl does 150mph? some say higher, and the vr4 only does 10-20mph faster with 100hp more?

aero

I had always thought the SLs maxed out around 140ish and the VR4s around 160ish, but it doesn't seem to look that way... I guess I was expecting a bigger number from the VR4s top speed... somthin more like 170ish?

i've taken my 93 base for several top speed runs. i can only get it to 125. there just doesn't seem to be enough power to get it beyond that. mine's pretty much stock as far as the engine goes. not sure how the other later SL's can get up around 140ish.

Turbo engines are also less stable than NA engines at their top most speed, to push it too much higher, it wouldn't be able to handle the compression and or speed... I don't forsee a much higher top speed for the VR4, I just see it getting there faster... but it also depends on gear ratios... throw a taller 5/6 gear in there... and you'll be able to go faster, b/c your rpms will be lower and the engine will have a little more headroom

[youngvr4]

the car weighs 3800lbs, its stable enough. 320hp vs 222hp should by far have a much higher top speed then a sl

in that case some claim to have run up to 172mph in there vr4. the gears are made for 205mph in the first gens and 225mph in the 6 gears.

its like saying the v6 mustangs top speed is close to that of the cobra.

but i'm not an expert on aero, yogs is, maybe he'll see this and give some input.

I hate to tell you I told you so but I think we are coming back to my first point...

I have no doubts that people have seen 140-150 on their speedometers but that can be 20 MPH off at that speed...

I don't know if many people realised this but most speedometers read high because it's regulated to do that. The problem is no-one regulates just how much higher (the law suggests 0-20% higher then the actual speed but gives penaties if it reads lower then the actual speed).

Also what type of surface were these people on... 140 on cold asphalt is very different from 140 on hot asphalt.

I guess my point is... I wouldn't take all these Max speed numbers too seriously.

[youngvr4]

me either

good point

2old man you do make a great point, I'd never thought about it that way
