How much power is enough?

Asked by itself, that question has no answer: too much isn't even enough! There's no such thing!

So let me qualify that question a bit:

99 Firebird Formula daily driver street-driven. Drag radials only. (pump gas, if that matters) I'll have some creative weight reduction but no gutting, hole-sawing, bumper-removing, etc. M6. And that's how it's going to run at the track, too.

After a certain threshold, is there any point to adding any more power? 500 RWHP? 600 RWHP? 700?

That is a question only the owner/driver of the car can answer. Some are perfectly happy with a stock 305rwhp while others aren't happy with 500rwhp.

Keep modding until you're happy or can't afford to go any faster!

When you start spending more time (and money) dealing with broken driveline parts and other power related issues and less time enjoying everything you've worked so hard to achieve.....or till your wallet runs dry....whichever comes first!

We figure about 2,400 will be enough for some 7.10's @ 203 MPH @ 3,000 LBS.

Mark Donahue once said something to this effect, "if you have enough horsepower to spin the tires from one corner to the next, then you have enough power". This of course was assuming a well sorted chassis able to apply this theoretical amount of HP. The point of diminishing return as it relates to power production is dependent upon the point at which you're not able to put it to the ground. Relative to most of the cars in this forum, that becomes a tire issue rather than a chassis/suspension one. If you can buy it and apply it....

THAT is precisely my question. For Drag radials, how much power before you can't put it to the ground?

LOL, Tony, I've heard of a few people who buy your heads and then just keep breaking driveline parts.

But I think I've put some sane limits on how far on want to take my car. It's a question of how much power will "work" for that kind of car.

LOL, that's some "street car."

Of course, everyone has a different idea of what they will drive on the street. I have mine, now I just have to get the details...

Is this in the wrong section? Should it be in drag racing tech maybe?

Doesn't anyone know? I'm going to be buying a block in the next week or so and I'm going to need to know how far I need to go with the buildup...

If you can DD ~550-600 rwhp, I think you'd be pretty much happy then. That seems like more or less the limit for a DD. In my eyes anyways. Procharger on a well sorted engine, maybe a bit of a shot, you should be good!

Thats as far as I'd go for a DD. Now if you wanna make it a "Weekend car" thats when I'd go TT with a low comp engine, and a well sorted suspension/drivetrain.

Those are my takes on your question. =)

I would be scared to race in or against anything thats making more than 600rw n/a on the street and anything than 800 on the street using boost or nitrous. I worry about if I could keep it in check if something happened, or if the person next to me could handle it.

Right now I'm looking at a 427. With the kinds of heads out there these days and the right cam, headers, intake, etc, I could easily see over 600 to the wheels.

If that's not enough, I'll have to build it in a completely different fashion so it can do boost.

If that's more than enough, then I can plan to go N/A.

That along with a solid roller thrown into the mix sounds like a nasty set up, but its only so much you can do traction wise.

Well, let me worry about how to make the power; the question is, at what point is it worthless for me to spend more money making more when I have no traction to support it?

If you are going to buying a 427 next week, then ask them. This thread has answered your questions several times over.

A stock LS1 M6 can break its 10-bolt. About 550-650 rwhp seems to be the limit for a DD. Move along.
