I am told by a mechanic that if you take two cars, one NA engine and the other a Turbo charged car, both with the same top speed but the Turbo is with superior torque. Now if you raced these two cars on a straight road for say 200 miles, the NA car will win handsdown. The turbo will be infront initially because of the better torque but once both reach the top speed then the NA car will finally overtake the turbo car because the NA car can drive at top speed all the way while the turbo top speed will taper and will not be able to catch up...it seems the power of the turbo will taper off

Is is true and not a myth or my mechanic talking cork?????

nope..turbo still wins...its superior torque great for acceleration after corner/overtaking other traffic...(200miles is a long way)...

-the area NA wins is handling on twisty roads because the driver able to fine tuning his throttle control far better and easier than the turbocharged car....


*the case power-curve tappering at higher rpm...the NA and turbo faces the same problem...when reaching its limit both engine wouldn't go any beyond...


inn fact..if the turbo engine was badly tuned with huge turbo lag the NA engine can gain advantage during acceleration over turbo engine... smile_approve.gif

Is this a trick question? If both have same top speed but turbo have better acceleration, how will the NA catch up....ha! ha! smile_big.gif

When F1 was in turbo era, it has a displacement of 1.5L only. Then change to 3.0 NA and yet Honda won the next two years on their turbo, before all have to change to 3.0 NA.....

You did not follow F1, or only the races...... smile_tongue.gif
When F1 on 1.5L twin turbo, power churning 800bhp. Initial switch over to V10 3.0L NA they could only get 600bhp.
But as they went along, with new tech, it slowly increased to 800bhp again, but then FIA ruling step in to cut the power for safety reasons.
Now they are running V8 2.4 NA and they are slowly bringing to power back to where they were before..... smile_thumbup.gif

No bro...this is no trick question. I am told if these two cars with the same top speed are to race on a STRAIGHT road WITHOUT any other traffic, the turbo will be in front first and will reach top speed first. But the NA will also reach top speed later and be tailing the turbo cars but maybe over a mile or so at the most, but the point is I am told an NA car will be able to keep that top speed for the rest of the distance, while turbo tends to taper in its power, meaning it just cannot sustain the top speed for very long, it will slow down and then pick up again.

this means over long distance a car with continuous top speed will beat a car with intermittent top speed. So is it a fact that a turbo car will not be able to sustain top speed over long period???

Bro rallychamp mentioned that when the track haas a lot orf corners, the NA will win??? In this case I believe the turbo will win in this case because with the extra torque it will be able to downshift and speed out of these bends and corners faster than the NA cars.

You mean, say a turbo top speed at 6k rpm, will drop to 5800 rpm after a while. If still at 6k rpm, top speed will not drop......
Anyway, I am not able to test my turbo that way and I still have my speed cut at 190km/h for safety....... smile_thumbup.gif

Turbo car will only build up quickly the curve power by the turbo charger with high boost , but once the car was on it peak power the turbo boosting will not contributed much..if you keep high boost the turbine to the max on peak power and very soon you will blow your engine, so for turbo car to keep remain the top speed with high boost in long distance will cause few issues in cooling systems that may effected the ECU to work on limp mode( mean max performance to reduce to safer measure) to protect the engine...

NA car will performance on another way with slowly build up curve power (unless your NA are big Vtec that can rev in high rpm) but once it on peak power it will just maintain the peak power easily as the NA engine are just love the high flow pressurize in take and will be less problem with cooling systems...

above comments are base on both car are traveling in 80% peak power in long distance..
