Ive got a 96 mustang gt and at the track I can keep up with most cars(9.32 in the 1/8 mile)but after 50mph my car is very slow(npi heads). So I was talking to a mustang shop about a pi swap and he said that its not worth it when compared to nitrous. I told him Im trying to do 8.5 in the 1/8 mile. he told me that it wouldnt be a problem with nitrous. I dont know which one to do. All the older guys are telling me that my car wont last with nitrous. So I dont know. My mods are below

 

a lot of the problem of falling off in higher rpms is because of the nonpi intake

 

hose that bitch.

 

PI swap and I've got the whole swap for sale if your interested!
