no. it may seem better but it would only be a few tenths of a sec over the 1/4 mile. a 2871 isnt really that bad anyway. think about this, your gonna be spinning rear tires faster and traction can be an issue with a lightly modded sr. now your talking about 350whp with a 4.63 rear end, you might not be getting traction until you hit the top of 5th gear. if your worried about spool time go with a 25-50hp shot of nos.
