I hope this is in the right section.

I have seached and seached and i can't find anything why people don't use a stroked motor for drag racing. I'm doing a 6262 pte Turbo and just want to know what would be better for drag racing hy.

Thanks

i would say a built 2.0 would be better for drag.

you want top end for drag and with a 2.0, youll be able to rev higher which is what will keep a big turbo like the 6262 in its powerband

Because when you increase the stroke of the crank, you increase piston speed, which limits your max rpm. With turbos like a 6262, they make a lot hp in high rpm, and that means good 1/4 mile time.

Definately a 2.0...Even a 2.1

For many its a preference. As has been mentioned some really like to stretch the rpm band and it is not uncommon to see many 2.0L engines running into the 10k band.

For those like me who seem unable to master the concept of the no lift shift strokers prove to be a bit more forgiving in that I don't drop out of the power curve as quickly.

When you get into the power ranges that bring our cars into the 9sec time period your really talking more about the drivers skill and style than the displacement of the engine if all else is equal.

I know crazy guy who has an evo7 with 2400cc engine (100mm stroke) revving up to 9500.
His best 1/4 result is 8.89sec (163mph)

same as what crcrain said... except that he forgot to mention that horsepower is directly proportionaly to acceleration...and therefore by increasing the point at which peak ve occurs you can make more power.

the "2.1L" has the same 88mm stroke as the 2.0L 4g63, but also has a taller deck with improves the rod to stroke ratio, which reduces the stress on the shortblock components.

Bigger displacement, like a 2.3 ultimately shines on road racing circuits, right? Where a solid amount of lower/midrange power is favored.

I've got a 2.2L stroked engine.. its certainly got what it takes for drag racing..
check out my garage pictures..

Check out the long rod 2.1...you can read about it on dsm-tuners.

2.0 ftw

This guy is doing REALY good with a 2.2L!

Correct. More torque/whp down low is important to road racing.

Look at all that torque that F1 cars make down low...

2.0, 2.1, or 2.2 you cant go wrong with the right set up!
