Ok I know we're about 2 weeks from Honda giving us the full figures for the Civic Turbo, but I'm impatient and curious.

So I went and found the figures for the Jade RS hoping for something. Now before you get uppity I know the Jade RS is derated and optimized for JDM fuel economy, but what I was really looking for was peak RPM.

150PS (148hp) at 5,500 rpm and 203Nm (150lb-ft) of torque between 1,600 and 5,000 rpm.

HondaProJason posted a photo on his instagram of the 1.5T making full boost just shy of 6,000 RPM.

So I think its fair to assume the 1.5T in the Civic makes peak between 5,500 and 6,000 RPM and we already know the horsepower is 174. Considering he would of snapped the photo AFTER already hitting peak boost, its likely closer to 5,500 but lets look at TQ figures from 5,500 to 6,000 RPM

Using the formula TORQUE = HP x 5252 ÷ RPM we can come up with a ballpark figure

Assuming peak HP at 5,500 RPM= 166 lb-ft
Assuming peak HP at 5,600 RPM= 163 lb-ft
Assuming peak HP at 5,700 RPM= 160 lb-ft
Assuming peak HP at 5,800 RPM= 157 lb-ft
Assuming peak HP at 5,900 RPM= 154 lb-ft
Assuming peak HP at 6,000 RPM= 152 lb-ft

You can use a HP/TQ calculator if you want to check my numbers http://www.1728.org/mtrtrq.htm

I think this is at least a good place to start our discussion, and I certainly like the sounds of 166 lb-ft of twist...

I've been trying to see if anyone listed when peak HP comes when Honda showed the new turbos in prototype form to try and corroborate what you found. Haven't been able to yet but I'll keep looking...

For what its worth in prototype form the 1.5T made 201 HP and 192 TQ. The TQ value is 95.522% of the power value. If we take LS calculation of 174 HP and 166 TQ we get a near identical percentage of 95.402%

Yea its a crude validation, but I think we're on the right track.

What might be more important for drive ability, we are probably looking at 175-190lb trq from 1500-4500rpm.

Agreed, will be nice seeing all the TQ available before 5K

My car before my accord v6 was a mazdaspeed 3. Stock that thing never really needed to be wrung out to pass people. Just part throttle at about 3-4k rpms and you would fly past traffic.

wow, the numbers here were just about spot on. The 1.5 makes 162 lb-ft...anyone know where peak TQ comes on?

Isn't the usual trend that peak torque is made just before peak power? If that's the case then we should see peak torque made 500-1000rpm before peak power.

shoot sorry, i meant peak HP. The above was calculated assuming peak HP at a certain RPM. I wonder if the assumed peak for HP is correct... my mistake >

I'd read that peak torque comes in at 1,800 RPM to 5,500 RPM.
