How fast is too fast for a street car? This is a question I have been pondering a lot lately and everytime I think I have my mind made up to the answer, something makes me change it. I look back over the years of moding my car and I remember WAY BACk in '97-'98 thinking that if I could have a street car that would run 13's it'd be "fast enough." Then I started adding mods until I got into the high 13's but I then realized that it really wasn't that fast. So the cycle continued and I added my heads, cam, and a few other parts hoping to run low 13's, and the car ended up running all the way down into the 12.0 range. Thinking I'd be happy with that it soon dawned on me that while I do have a "quick" street car, but its not "fast" relative to the other cars around here, especially concidering what some of the OEM stuff is running off the showroom floor these days. Around this time is when I hurt my car and I have since been planning my next round of mods, but now I have to a cross roads and the question again is coming up, how fast is too fast, and this time it is a little different. At this point my options are limitless in terms of what I do to the car, but it snowballs out of control rapidly. I could always add a high compression 347 or even a 393 to my car and pick up maybe 100 more RWHP, but I don't think that's enough to bump me into the "fast" category as the car would still be slower than most here run on a stock shortblock with H/C/I and a vortech. I could add a turbo or supercharger to my car and lay down ~500rwhp, and from where I stand I think that would be on the verge of a "fast" street car, but then you get into needing a new fuel system (which opens you up to making up to ~900rwhp), a new stronger block (which opens you up to making >900rwhp), a stand alone etc.(these are parts that I consider mandatory at this level, I know some try and do it with the stock stuff but I wouldn't if I was in this position) and if you are going to go through the expense of doing all of that why just build a stock displacment, why not stroke it, add better heads, a bigger supercharger, etc? I got caught up thinking about these magical builds and when it was all done and I sat back and looked at what some of the things I created on paper would produce, I think they would all be TOO fast for the street. I mean, my 300rwhp car will only spin the tires in 1st gear when its cold out, after that I can got WOT all day in every gear and not think twice about it, however what would happen with 450, 500, 550, etc RWHP? This got me thinking what would be too much for the street? A dart based 347 with a good H/C/I and a turbo can make over 600rwhp, is that too much? A 150 shot on a high compression 347 could make ~500rwhp, is that too fast? I know we all at some point think we'd all love to have 1000hp daily drivers, but I think most of us know that its just not reasonable to have so much power on tap IN A STREET ONLY CAR. A few might disagree, but I'd like to hear what you all think.
