I was wondering what these cars top out at.. I get mine doing about 125 in 6th gear and it just doesnt seem like it wants to push any farther... I get stuck at like 5,500rpm in 6th.... Is this a problem with all the Si's and what can I do to have the whole RPM's in 6th gear?

 

It has a limiter on it. Temple of Vtec did a test on the Si. They estimate it doing 157 MPH (I believe).

 

So.. How would I go about getting rid of this limiter??

 

Where he hell are you going that you need to get rid of the limiter? I'm pretty sure the Texas speed limit isn't higher than 125mph.

 

/\ Hahahahahah.... owned.

Most speed limits are between 60-70 MPH on the highway in Dallas. Alot narrow lanes too. However, there are surrounding areas less travelled and very open.

 

Yeah but come on, going 125 mph is bad enough, I'd say anywhere from 110 and up you're asking for trouble. Best to stay away from it. I don't want to read on the news that some guy rolled his Si 20 times because he was doing 150.

 

I agree. This issue was discussed before, and it turned into a bitch fest.

 

calm down guys...I think he just wanted to know how fast it would go...instead of going into 6th stay in 5th for a little longer...it should get you up to at least 130...after that 6th gear is for **** to move any faster...Oh and the redline test that someone did went up to 157 mph...they took the front wheels off and put it on some machine to redline the 6th gear out.

Been awhile since I saw it so I wasn't sure.

 

no worries...if someone could post the video of that...I think its on You Tube...its pretty nice.

 

The redline speed in 6th gear is a theoretical speed--it will reach 157 on the dyno because there is zero wind resistance. Considering the power and aerodynamics of the Si--if there was no speed limiter I am guessing between 135-140 mph at the top.

It takes exponentially more power the faster you go. It might take 200 hp to get to 140 but you might need 275 to get to 150. And it goes up from there.

Enjoy!

 

Thats a Dynapack hub dyno.

 

anyone know the top on a base civic?

80 MPH

Just kidding. Haven't seen anyone do a test on a regular civic. Probably around 110-115 with the limiter.

 

145mph

very funny

 

I know that the DX FA will do 105 stock (I did it when I first got mine to see if the speedo would hit tripple digits) then later I realized I could have just put it into KPH mode and found out lol

 

Ive done 120 on the Taconic and it was still pulling so it def goes more then 130 thats all i know !

 

Didn't AJP hit 190+ in their shop car?

Assuming the speedo is a bit inaccurate at those speeds, I'd still assume that's ore than 167 no?

 

After 188mph the speedo just went blank reading 0-0-0 but it was fun

 

i did 110 in my lx and wasnt that close to redline, didnt try to go any faster tho

 

Before I traded my Ex in for a Si I got it up to 124 and hit the gov. The fastest I have been able to get my Si up to would be 133.
