All depends on the driver, plenty of ******** who shouldnt be allowed to drive their 300hp cars on the streets.

For me personally, I'm not sure. 531rwhp wasn't enough, I'm shooting for 800rwhp on the next build, we'll see from there.

I think the main factor is how streetable the car is and how you plan to drive it. By streetable I look for suspension and brakes. Its one thing to propel your rocket down a racetrack with a good amount of room to stop, and quite another to be able to get your car up to speed quick and be able to stop/turn with an equal quickness. ie: Takes a stock LS1 about 13sec to get to 100mph, if it now takes only 8sec to reach 100mph you should be prepared to deal with obstacles a lot quicker.

How much is too much? Too much is more than just what it takes to hit the speed limit.

Too much for me? Whatever gasoline can top out at.

I'd say N/A, 500-550whp is the limit. You start running into crappy idle, drivablility issues when you have to run that radical of a cam. Running a boosted motor is an entirely different ball game, you can have something with 600-800whp that has the street manners of a stock car.

I really want to do an LSx turbo build on my 1991 Cadillac Brougham. It would be fun to run low 11's in that car with great street manners and working a/c.

Depends on the car and engine. To me if the car can still idle without dying and take off from a light without doing a burnout you're fine. Any amount is too much with an idiot behind the wheel.

I would say too much power for the street when you're in sixth gear and can go from 70 to 140 in a few seconds w/o down shifting...

You can never have enough power, it's addictive like crack. I guess when you got to use throttle control to keep the rears from spinning in all gears.. It's just overkill at that point on the streets..

I can spin in the first two gears and cherp third and that is getting old fast. If I could spin third gear and cherp 4th I would be the man, but I can't!!!!! I would need another 100wrhp and 100 torque to pull that off probably..

this shouldnt be a question for how much power is too much for the street... cause hell, a stock fbody has that....

it should be a question of how much is too much power for YOU! and that answer for most of us, strip or street is.. not enough!

So I guess I would say for a daily driver 500 but weekend warrior the limit is unlimited.
i agree because more hp is just going to get you in more trouble

I think that at about 700 rwhp you have trouble hooking on the street even with ET streets so probably around 700 RWHP because with 1k RWHP you sure as hell will have trouble finding that thing called traction!

yea thats a blast. its even more hilarious when your on the highway and pass the car in the fast lane going 90 mph. then switch lanes get in front of them and hit it and leave black stripes all the way up to 140 mph! the look on their face is priceless!

Anything inthe 10 second range with a healthy trap speed of over 126-127mph is more than enough for the street. Whatever power that gets you... for me that was 520 ish whp and 3450lb car. That car would get up to speed soo quick on the street with the nitrous shot and on cold roads it spin tire at 50mph rolls when the nitrous hit.

Too much is when you cant fully use it all or if the car gets up to speed soo fast in a short amount of time, you cant really go down on the throttle for more than a second or two.

That being said, i'm shooting for 700-800whp with the new twin turbo setup, and I expect that car to be too much for the street and hope to have a low boost setting to get me around where i was last year... 550 ish whp

I would say 500 to 550 rwhp would be ideal. With that much power you could drive aggressively without having to worry about going over half throttle.

i think this about hits in on the head... i have a 425rwhp stalled a4... car weighs 3k lbs...

my "full throttle" is more like half-3/4 throttle.. im so use to only giving it enough gas to "have fun" sometimes when meaning to go WOT i dont..
