Default why the torque curve of the legacy engines?

Is it just the turbo that has this characteristic? everything else i could find said the engines were the same....

two LGT stock dyno graphs
http://legacygt.com/forums/showthrea...ght=dyno+chart

a d.d. dyno read an ecutek relashed lgt at about 208hp and 215 tq here
http://legacygt.com/forums/attachmen...achmentid=3101

and 202hp 231ftlbs
http://legacygt.com/forums/attachmen...achmentid=1083

211hp 250ftlbs with stage 1 cobb ecu flash 14.7psi....
http://legacygt.com/forums/attachmen...achmentid=3748

and official cobb results
stage 1 285hp 305ftlbs totally stock lgt 14.5psi MOST of torque by 3k
stage 2 300hp 345ftlbs 3 inch dp and 2.5 inch mufflers (2 of them) 16.3 psi and max torque at 3200rpms! I like that!
http://www.legacygt.com/forums/showthread.php?t=6872


To be honest, I kind of like those last 2.... that would be a very useable engine for autox.... i wish i could shut my brain down sometimes... Matt

You can get massive midrange on a Sti using the same methods of tuning.

Also the stage 1 map is intentionaly detuned on the AP. Don't know why, but it is.

It is really helpful to look at the boost curve at the same time.

I think you will find the VF-40 just runs out - it is really tiny.

Today the biggest drop in turbo is Deadbolts 18G which is still pretty small. If you want a real turbo today you have to change a lot of plumbing .

Those are very nice gains with very minimal mods. Have you tested a full turboback yet (do they even exist)?
