What is the top speed on a brand new stock 07 Si with the speed limiter?

Not as fast as my '73 corvette, rice burner boy!

I would guess 120mph. I had a 91 honda the governed at 120. Might not be right though, just a guess.

I like the corvette guys answer waste his time to come into a different forum and post like what he is really saying is important probably he feels big and bad that he has a covertte and being 40yrs old nice, Im half his age and have an E55 06, um sucks to be you buddie and thats not my daily either.Most Si are 125mph stock. So I sure its around 125mph. The gearing of your transmission wont let it go past that also maybe 10mph or more.

I got an 07 Si.
and 5th takes me to 131~132 if i redline it
and 6th goes up to 135 then governor kicks in at 135.
Interestingly enough, it climbs prity well in 6th to 135, and governor kicks in at 135 which is exactly right before 6k rpm's which is the stpck vtech point for my 07 Si. therefore I'm curently looking to buy another ecu to have it reprogramed.
(wana keep my stock ecu for waranty isues, i got 75k waranty)
i'm prity sure that if governor could be removed, that 6th gear with another 2k rpm's before redline would definately pull in for good 10-15 aditional mph.
or possibly more. (never bothered actualy calculating mph/rpm by using Si's 6th gear ratio).
In short, I'm sure this car with removed governor, could pull into 150's

(keep in mind, my car is completely stock. not even a filter)
(also keep in mind that i found out that Si's with their stock 17's are slightly lighter then the optinal factory 18's)
