I'd take a tame 500rwhp turbo setup anyday over a 500rwhp NA car.

A good Head and Cam car should beat a forced induction car with all things being equal. Same driver, back to back runs, same tires, same gears, same everything . N/A wins over the Forced induction in a 500 rwhp race. On the other hand that FI setup is capable of a lot more. The N/A setup is close to all that can be made out of a stock cubed N/A LS1. Just my 2 cents.

The thing is that it would be stupid to build a FI car just like a NA car. There are different torque/power curves. It would make no sense.

I am not saying same cam. I am saying a cam that is spec'd to make power using forced induction on the FI side of the coin, and a cam that is spec'd to make power N/A on the N/A side. I am fully aware that a cam with a ton of overlap is great for N/A apps, but not a smart choice when going FI. The overlap allows a loss of boost.

its all about area under the curve. what one motor makes compared to another at maximum HP and RPM is not even half the picture.

take two stock LS1's
on one, slap on a maggie or say a turbo setup. its a mild setup, so lets say your at 400hp max. but it makes 400ftlbs from 2K to 6K.

now take another LS1
and put a wild cam/head combo.
you make 500hp @ 7K rpm., but its very peaky and lacks in the low end torque dept.

Id choose the FI option for anything but oval track racing.

N/A car would win and be less expensive.

I would have to agree with you.

If we assume :

both cars weigh the same
both have same transmission/suspension
Only difference is NA vs FI
Both cars have equal amounts of traction due to suspension setup

If the car has a 2 step on the FI setup, the car can build boost before it even leaves the line launching with more power then the NA setup.

This is also assuming it doesnt break the tires loose.

CI also does come into factor.

If you look at a 500rwhp 346, your gonna be running a trex cam or something HUGE with an all out bolt on requirement.

If you look at a 408, you can run a smaller cam AND have more area under the curve, allowing you to pull harder in between shifts.

You can probably run a t60 turbo or even smaller on a 346 and have full boost very very fast (assuming backpressure isnt too great) and have tons of area under the curve (especially in the tq dept).

If you look at all those 500rwhp NA cars, they usually dont have more then 450rwtq at most.

There are tons of FI cars that ive seen with 500rwhp 550rwtq.

Thats just my opinion though and im stickin to it

Too many variables. If you are talking an equal displacement setup than a properly sized turbo would most likely have more mid-range and be faster. A mild, larger displacement engine Vs. a smaller motor with a turbo would be a closer race.

all things being set up right, turbo all day everyday. yes even at 500 rwhp,why ,TQ is what gets you going its HP that keeps it going in the 1/4 mile tq wins...
a 500 rwhp n/a isnt going to have as much RWTQ as a turbo even if they are both 500 rwhp. turbo=TQ!

Quickin

N/A for sure. Unless the FI car can leave the line at full boost and hook perfectly, I think it would be hard to match or beat the N/A car. Also, if its a stroker it'll have big giant torque and you have better control of the power with N/A.

i just love the fact that the NA motor will make your ears wanna bleed when its going to redline at about 6500-7000rpms, and FI seems more expensive in my opinion

does anyone know details on the vette in this 1st video? motor size and things done to it? Who's car?

Nothing like un burned fuel igniting as it comes out the tail pipes...WICKED

Who knows. The car that makes more AVERAGE horsepower between the shifts and has the weight advantage would win the race. Its impossible to judge the outcome simply based on equal peak numbers.

I vote for the N/A setup... maybe its because I have a 508HP H/C car though... LOL

I just think there is less things to worry about, no worries of overboosting, no worries of sliping belts, I think its just easyer.

haha... nice

But its not about over boosting or slipping belts...

Its about if things work the way they should making 500 rwhp, which one will win.

You can **** up your oil pressure and spin a bearing in your NA motor, but that has nothing to do with winning, cause it could happen either NA or FI.

Yeah, you'r right. But I was just saying that it seems to me, from what I have seen at least, that there are less headaches in making 500 N/A then on Boost. The boosted 500HP car will be more streetable probobly because you could most likely do it on stock heads with only a slightly larger cam, but my car does just fine on the street.

I guess what I was trying to say is that with a Boosted car, there are more componenets so it seems to me that more things have the potencial to go wrong or overlooked. Just easyer with N/A IMHO. Maybe not cheaper, but easyer.

As far as which one will win? Depends on the driver I would have to day. A boosted car is a lot more sensative to slow shifting then an NA car, at least from my experience. So if you shift slow, and let the boost fall on everu gear change, the same driver would probobly go faster in the NA car. If it's an auto then I think the boosted car will win due to higher torque.

But that is easy to find out. I can run mid 10's all day N/A. What do 500RWHP boosted 6spd cars at 3325#s run? Not being a dick, I honestly never checked.
