No kidding, what is the top speed of a stock SVX?

This topic was posted in the past but there was a lot of "debate" and no consensus from what I could tell. 143 MPH is the most often quoted top speed. Someone in another thread said the original Subaru claim was 146MPH. I have seen people claim 152 MPH and 155 MPH. But it was never clear if that was a fully stock SVX. Modified SVXs have gone up to the 170s but that's not what I am talking about here. I would like a solid and reliable reference point for the stock car.

Does anyone have reliable information on this?

Re: No kidding, what is the top speed of a stock SVX?

Look up "SVX Vmax" on Youtube, I believe there are two parts. (I'd link it, but Youtube is blocked on work computers). It shows a guy with the speedo pegged.

As to the infamous "speed limiter", no such thing exists in any real sense. Tom brought up somewhere back that there is one, but it's at something like 400 MPH and not really about speed anyway, more an engine parameter. (If I'm remembering correctly, it's been a while.)

Re: No kidding, what is the top speed of a stock SVX?

Place the tire diameter in a "perfect world" scenario and add gearing and max RPM:
Tires: 215/55/16 (some years)
4th Gear: 0.694:1
Diff: 3.54:1
Redline: 6500
Max RPM: 7000

Tire Dia.: ~25.31 in
Tire Circ.: ~6.63 ft

@6500 RPM: ~199 MPH
@7000 RPM: ~215 MPH

Right?

That's not to say that it has the horsepower to get there...

I dunno. A buddy of mine had a Stage 2 STi up to 172MPH, which was the gearing-limited top speed. (He just happened to have access to a very long airport runway.) If a brick can do 172...

Whatever the top speed of the SVX is, it's the same (or very close) for all years.

Unless they added a speed limiter in the OBD2 cars? But I've never come across that.

Anyone want to go out to an airstrip and find out? I've got my 6-speed and a '97 that we can try.

How's the friend?

Did you use GPS or the speedo to measure that speed?

I've texted my brother in law to see how fast he got my black car up to when it was new. I know he got it above 100 quite a few times.

He said the fastest was 148, but I don't know how hard he was trying.
