why are you racing over 100mph on streets?

now that I've got that over with.....
you're losing above 100mph because you've got around 200whp. Of course you're going to lose. Those 4.77's aren't helping you at all. Gears on low power cars are kinda like mechanical band-aids for lack of power.

I'd put the stockers back in or something less aggressive if you're going to run a good shot of nitrous. That, and those 4.77's lowered your top speed a bit (I'm not sure how much, but a bit)

 

145 I believe. But i can run a shot in 3rd+ gear. just 5th and 6th are sluggish.....

 

that's because 5th and 6th are considered overdrive gears....that and at those speeds, there's not enough power to overcome the drag.

 

/\ hense the nitrous

 

To do it right you will want your car tuned to make use of the extra power.

Otherwise your computer is just making a best guess estimate @ what it needs to do w/fuel/air.

Of course there is a decently high price tag associated with that, thus the reason n2o has a bad rap. Most people bolt it on, blow up their motor and blame it on the spray. Had it been tuned, they would have been alot safer.

 

tune with what tho? Vafc?

 

use an emanage ultimate. But you don't need to get tuned for anything 75 shot and below. Over a 75 shot shot you should get it tuned.

 

Maybe ill take the spray out of my DD and put it in the S

 

I think it's with anything over a 100 shot you'll need a tune, if your look for a bigger shot than that you might want to think about building up the bottom end.
