Same experience. I think it slowed the most after 139. Never went to 6th gear and was at about 8750ish rpm. Greddy Sp and MS CAI only mods.

 

im surethe intake and exhaust helps a decent amount at that speed. you use every single 1 of your ponies.

 

262km/h = 162.8mph with GPS

Got a little more to go but the roads are not made for these speeds and my 8 gets a little nervouse at those speeds (me too).

 

do you know what you are putting down to the wheels?

 

=0 dang

 

200whp @ rototest if I remember correct.

Rototest is a bit conservative, a SUN would probably give ~210whp I guess.

I personally don't think these speedo's are the most accurate!

 

My speedo showed 276km/h when my GPS showed 262km/h, but I don't run on OEM tires.

how off are our speedo's stock?

if i'm doing "60" what am i actually doing?

 

in 60 is 59
and in 120 is 118

 

MAX FART = 262 km/H

 

yup 148. gov kicked in and went down to 110 real fast.

 

^there is NO governor on the MTs....the only reason we stop there is due to drag...

 

hah ya definitely no governor. One way to tell the validity of the claim is comments like "ya it hit the governor at 148 and went down to 110 real fast..." Haha ya right the governor kicked you back 38 MPH!!



I got up to almost 150 or so but ran out of straight. I also realized later that I had unknowingly left on the AC unit. That could have slowed me a mile per hour or two.

 

Naw , his engine just blew lol. (compression test anyone?)

 

Id like to see a turbo8 run the salt flats wonder if drag would keep it from hitting theoretical 189mph

 

The front end got a bit light at this speed. I would like more downforce on the front. My car is stock.

 

i would give it a tune up......coils, sp's, air filter....should be easy to get past 138

 

No such thing in my car. I can take it all the way up to 10k no problem.

 

i've ran at 237kmh or a 148mph for 5min+ those numbers were off my gps my speedo was saying 249km/h im running 225/40/18s

 

Just curious ... what kind of gas mileage do you get at 148 mph haha ?

 

I can watch the needle drop slowly

 

JDM spec - stock except for AP calibration (more BHP & Tq) and no limiter gets 160+ FACT!

With regard to speedo, that figure is a very good estimation made from the revolutions of the wheels. GPS can tell you exactly what speed you're doing.

 

I also quit at 135 one time due to the same thing. My car is now lowered and that should help keep air from getting underneath and causing lift.
