Yes they do my Vx Civic started even further in the hole with only 92hp stock. It was an economy car. Then Neal put in a GSR motor for me and I ran a 13.8 @ 100 with just a K&N and exhaust. I know my car isnt blazing fast but even these days its quick enough to win 90% of the time. Youd be suprised how many other cars(V8s and imports) Ive filleted on the streets over the last three and a half years. I must admit I do have a much better record against Mustangs than I do against F-Bodies. And people who do spank me on the road get my respect and a thumbs up not a ricer fly by.
