Any One Find The Speed Limiter

Notice that it's only hitting 5800 rpm at 134 mph! Dang! It's got more in it! I calculate another 11.5 mph for another 500 rpm. That's 145mph for 6300 rpm. I think it has the stuff to do it! Wow.
 
Useless until you run up against your first WRX on the highway. My buddy's car stops the fun around 141. Now we can't have the soobies running away from us now can we???

Actually going to run my car at Pocono International Raceway this summer. Lots of passing on the banking if you don't have the top end..... My old Civic Si read 147 on the speedo on that track so at least the WRX's did not get away. A little more worried this time around on the straights (not as worried in the twisties though:).
 
When I get turboed I am actually going a different route. I am shrinking my final reduction to increase top speed. Problem is, I need the torque of the turbo first. My goal is 55mph around 2200rpms in 5th. I will be slower than other turboed prot's, but my god, highway cruising will be freakin' beautiful.
 
yes i have ran 135 also but i didnt notice the car topping out.... i believe it was still going, but that could just be because i kept looking in my rearview window laughing at the fool in the nissan maxima. haha couldnt keep up, his car wouldnt go over 115 or 120. i know maximas are faster than that. im sure it has something to do with him never doing routine matinence work such as changing the freaking oil and filter!

much better gas mileage too

*implied in earlier statement* :D
Agreed. That is the great thing about big motors, they may be incredibly inefficient at high revs, but you can change your final to remove a lot of the torque and improve gas mileage. We had a 1983 GMC full-sized van and shrank the final. That thing carried a 6-person family all over the country (I mean like 42 of the 48 contiguous states) and got incredible gas mileage. Flip side? It took about 14 seconds to get from 0-60, literally. Like a ******* bus.

On the mazda, one could easily see well over 35mpg on the highway, if we could just get over the f*ing problem of the ECU going rich under even mild highway acceleration, presumably it does it to prevent knock. That is why non-cruise highway driving yields such unimpressive mpg's.
 
Is the speedometer accurate at high speeds? Or is it like Bimmers in that they exaggerate.

Man I get that allready. I drive 100 miles a day to and from work and shift 1,3,5 then baby it up to 60MPH and pretty much do that for almost my whole trip with the exception of the slower areas in which I have to drive 35-40MPH.
I get about 420 miles out of 12 gallons. In fact it's so good Im worried about what more boost will do to my milage if I drive conservatively like I do now.
