Where is the high end of usable Horsepower and .......

[tyoneal]

Hello:

From reading this forum, my own opinions being omitted, there seems to be a concenses that 400 - 550 RWHP seems to be the upper limit on what is usable either on the Street or Track, and also what is just fun to drive.

Drag strips are the exception as strait line acceleration removes a number of issues that the previous examples have to deal with.

Another issue I would like to ask is, "How is the Best Way to make this power?", while retaining:

- Drivability (Quality vs. Brutality of the power delivery)
- Fuel Economy
- Long Term Dependability
- Handling Performance (weight etc.)
- Bang for the Buck (Cost)

or

What power plant configurations best included these characteristics?

I look forward to your opinions and advice.

Thanks,

tyoneal

(I'm guessing a well built, hot LS-2 Engine, would probably be one of the better choices)

For the HP range you are talking about and the other options you mentioned:

- Drivability (Quality vs. Brutality of the power delivery)
- Fuel Economy
- Long Term Dependability
- Handling Performance (weight etc.)
- Bang for the Buck (Cost)

LS1/LS2 is the choice.

Thanks for the response.

Any more thoughts about the amount of usable power?

LS7 would score well on all those points except cost.

[Ummgawa]

Super charge an LS-2.

[Stuart Adams]

To average all those factors an LS motor is probably best, IMO.

Jim, steaks at SEMA?

Tyoneal,
When you say track are you asking about a road course? If so, I would also like to know what some peoples opinions are.

I agree with the well built LS2

Yes, when I mentioned, "Track", I was meaning Road Course. Since this is a Pro-Touring Site, I thought I would focus on the Handeling aspects of a Powerfull Sports Car.

I think (Perhaps wrongly) that going straight with big horse power is relatively easy. Now manipulating the car around a challenging track is much more difficult, especially with big power.

In the 70's Straight was the Deal. To me in 2006, Straight as well as around a Road Course is the new goal.

Your thoughts??

How would you build the LSx engine specifically for this application?

Could you stay with an aluminum block and make durable 600+ horse power?

The aluminum block LS1/LS6 block will handle anything you can throw at it.
