C6 z06 vette whit 800 rwhp

[pagani]

This could be the perfect all round setup street road course and dragstrip all whit one engine.

Impressive beast !! I wonder what it is on the road

That's all well and good, but now I need to see how it puts that power to the ground. Building a Dyno Queen is the relatively easy part. It becomes an entirely different challenge making all of that power work outside of the garage setting.

Dyno is only for tuning.
I agree whit you.
Making the 800 whp real world hp is the challange.

Those types of cars are literally a dime a dozen out here - just yesterday 2 super charged C6 Z06s where at MTI - this is nothing special - honestly - great to see and hear, but so unbelievably easy to achieve.

The supercharged V8 is wellperfected, these are almost to the point o fbeing "easy bolt together" systems when tackled by knowledgable shops.

The problem as Minacious points out is - "Where do you want to be able to use the power?"

All these supercharged/turbo charged street cars suffer from dreaded heat-soak on a road course, and that results in pulled timing which ends up with less power to the ground.

This car will make an awesome street car, and woul dbe ok for 3 or 4 laps at a time on a road course before needingto be parked to cool off (same is true fo rall the high HP super/turbo cars).

Now an 800rwhp NA setup would be neat

And most turbo cars that run on road course run lower boost and have proper cooling outerwise things will meld very soon
A 800 whp na setup is something for you.

But as soon as you run "low boost" you are back in NA territory and all the supposed advantage of rnning boost in the forts place is lost.

Now remember, just because you run lower boost does not mean you get rid if all heat soak issues - it just means you can run a little harder for the few laps you do run.

I did a lot of soul searching before I settled on a NA setup- and in the end, I prefered to pay more for an NA setup that makes less power than a cheaper blower setup.

Street running is one thing, but road race course stuff is much tougher on equipment.

I would love to have a 1000 street car, but I know it won't be "all that" on a road course after 5 minutes of thrashing - he'll even the almighty Veyron has to come in to cool down after few laps

Proper cooling can fix allot of problem's on forced induction car.
But you have to run lower boost.

I am not trying to be an asshole here - but dont you think the actual companys/racers and people with FI cars don't know this and have tried various approaches? - but the bottom line is you cannot get rid of all the excess heat that affects a streetable pumpgas car. Even the Veyron with its 49 intercoolers and 86 radiators reduces power, pulls timing and slows waaaaaaaay down when it gets hot.

The very point of "running lower bost" defeats the purpose of having a super/turbo charged car to begin with.

To put things into perspective, in 2002 Lingenfelter had a 660bhp Twin Turbo C5 Z06... peple bought them, people loved them - LPE built them - but in a road race situation heat is an issue.

Fast forward 5 years to 2007. A number of people have 660bhp NA C5 and C6 Z06's - without heatsoak issues.

Guess which cars are prefered to be used on road race courses?

You see, it doesnt really matter how little boost you runn (for a turbo) or how big of a pulley you put on the supercharger, compressed air heats up - this heat soaks the engine, the heat soaked engine sufferes from pre-ignition with regular fuels and wold self destruct if the cmpoter never senses the knocking and pulled timing - resulting in the car being hot and slow

Didn't you ever figure out why Best Motoring only ever run 3 laps for the their tests? It's because none of those modded turbo cars can run more than 5 laps before they get hot and slow down

Why super charge it when you can go NA

Very leanlier power curve btw.

The main thing is turbo lag on a road course. Race cars have anti lag systems, but a street car doesn't. even on low boost with awesome heat dispersion.

Not all turbo engines have lag you need spec a engine properly and stroke the engine and keep it in the rev band
Just look at the new nissan gtr it has zero lag.

I don't believe that one ounce.

I think heat and lack of progressive powerband are bigger issues than turbo lag. It's to do with how you set up the turbos - do you go for max power (i.e. makes the power at top end - like the F40) or max flexibility (like my S4 and the RT12). The latter hardly have much lag to talk about.

In my car, the power comes on at 1950 rpm so there isn't that much a lag so to speak. Yes, you can be caught flatfooted when you are in low rpms and high gear but you will have the same issue in a NA car which is out of its powerband.

You are spot on.
It also helps on turbo engine to stroke it to bigger displacement.
A well setup/build turbo engine can just be as good as any na engine.
