Modifications to get hp in north america

I know this has been up for a while, but I would look into lightweight wheels, and such instead of adding horsepower, take some weight off, your tires will spin up faster and will feel like an add of horsepower. Maybe fiberglass hood, I'm sure that's out there somewhere.
 
Changing the wheels to reduce weight will minimally impact the acceleration performance of the car. We're not talking about putting in a lightened flywheel here. The only real advantage with lighter wheels is with unsprung weight in how it affects handling of the car.

The 2.0L engine was never made to be a performance engine. And any attempts to change that will impact the reliability of the engine for little to no gains. If you wanted a faster car, you should have purchased something with a better engine. It's too bad Toyota chose to give us North American customers the shaft with no options that are available to the European market. They at least have a hybrid engine option that gives the car some decent get up and go. Frankly the engine used in the new Corolla Hatchback and the Lexus UX should have been in this car from the beginning. Well, Toyota fixed that problem recently. But they did it by introducing a new model called the Corolla Cross. If I were in the market today, I'd get the Cross over the C-HR hands down.
I only mentioned the wheels because there isn't anything else to do to this to add HP except lower weight somehow and since you can't really remove the seats because you need them you'd have to look elsewhere
 
Two different types of vehicles: Cross vs Corolla. Compare the Cross with the C-HR and the Cross would be a speed demon in comparison.
actually the heavier weight of the cross negates the difference in HP so it's basically a push when it comes to acceleration. the C-HR feels a little quicker because its a smaller vehicle
 
but I hear where you're coming from...I'm done with speed, a long time ago actually, the days of the turbo T-bird, the Mustang GTs are LONG gone for the reign of Jeeps I had...so the speed is irrelevant to me. I needed something that gave me more than 15mpg, and I fell in love with the style of the C-HR...

I'm just concentrating on the visuals of the car and leaving the drivetrain stock for best longevity.
 
Actually, the engine does make a difference. Numbers don't lie. From Car and Driver's own test. 0 to 60 for the Cross is 9.2 seconds. The best 0 to 60 the C-HR can produce is 10.5 seconds. That's a full 1.3 seconds which is a big difference.

I know the numbers but I can only tell you from my experience driving both cars back to back...my C-HR is quicker than the Cross right now...after they are both broken in, that may change, but 1100 miles on the cross, 300 on the C-HR...C-HR has more gusto...and the C-HR has a sport mode, which I don't see the numbers for that...but both these cars are not about sheer power as you know...

it's a shame that people buy them expectting to speed around, especially the C-HR because of the style
 
Another thing the Cross will always have over the C-HR is the speed of launching the car at a dead stop. The Cross has a physical first gear in the trans. The C-HR is all CVT which is junk for any type of performance acceleration. You can readily feel this yourself. Stab the gas at a dead stop, there's always a slight delay before the car actually moves. It's the way the CVT works that gives that delay.
the C-HR has that same physical gear in the tranny
 
well, there are conflicting reports. According to "The Car Care Nut" on youtube (master Toyota mechanic) they put the K114 in the USA car, and not the K120, but in other reports and other reviewers say the tranny HAS the gear, so I would love to see your source to confirm.
 
according to the specs on the website for the cross, you are correct that it does not have the launch gear...but I have watched MANY MANY videos that said it does have the gear...funny that the info is so wrong in so many places. maybe it was supposed to have the transmission, then was changed at the last second. either way, both cars accelerate fine, they're not Lamborghinis or even Mustangs, they are what they are and they need to be driven accordingly, just like every other car out there...

I appreciate your knowledge and thank you for making me look a little harder into the facts.
 
I'm doing slight improvements, I have AT wheels since I'm in north in woods with New England. will add a lift, new suspension, break system. the cool air intake may be a possible upgrade but I feel it will be worthless. I want my c-hr to look like an off road car and feel like one with a kick up speed. any ideas
trade it in for a 4Runner with 4WD
