Well, when it comes to cams, those "little" difference make a big difference. Just go compare all the stage 1, stage 2, and stage 3. Those all have very "little" difference but they sure make different Hp.
I am fully aware of what is little and what is big when it comes to differences in cam shaft "sizes" the .027 of an inch larger on the exhaust side does help. I never said it doesn't. I was only saying that the amount of money and effort to get these cams into the car does not seem worth it.
Just by the measurement and visual comparison, I know the TSX 06+ will give more torque, low-mid power, and 5-10hp uptop.
Like I said I do know they will make a little more power throughout the rev range, I just don't think it’s worth it. I would rather toss a "bigger" cam into the motor and make more power if I am going to spend the time and money to install and pay for a new tune.
I personally think TSX cams are a great deal. You get OEM reliability and Power where you need it.
With most aftermarket cams you lose a lot of low-mid range power and only gain at the last few rpm. But now you have to deal with your chain tensioner breaking, rought idle, horrible daily driving, and increasing wear on your engine.
Can I ask you what cams you have ran that have given you any of these stated problems ?
Our in house motor has 130k miles on its stock tensioner, just over 70k miles of those have been with aftermarket cams (not even very good ones at that), 60k of those have been with a 9100 red line, beat on pretty hard. Still works fine. The tensioners normally give out due to improper installation, oiling issues, or if someone is running one of the select few cams on the market that happen to kill tensioners. At least this is in my experience. I am sure there are a few bad ones out there that have killed tensioners even on stock cams. It happens. I am just tired of people thinking they need to buy one of the outrageously over priced tensioners if they put after market cams into their motor.
On this subject though, as a safety precaution I do recommend anyone that has a reasonable amount of mileage on their motor to replace their stock tensioner if they are cracking open the timing chain case. Stock cams or aftermarket.
Outside of VTEC killer cams, I have never seen a car have a rough idle. A tiny bit of a "lope" maybe, but never rough. Isn’t that the cool part about vtec? low speed and high speed cam profiles
Horrible Daily driving:
Once again, I don’t really understand what you are getting at with this one. Can you please explain how I will have horrible daily driving going with even a decently sized stage 2 style cam? We built a 270hp K24 that fired up and ran just like stock. Hell, it started quicker and got better gas mileage (mainly due to a good tune with this one) than the stock K20 that was under the hood before we put the built motor in. There are other mods that will make a far larger impact on daily driving comfort than aftermarket cams.
Increasing wear on the engine:
Yes, this part is true. Anytime you change anything on the motor, you will most likely be increasing the wear on your engine. Driving the car hard will increase the wear on your engine. It’s part of the modifying game. Anything that will cause the motor to make more power than stock technically will increase wear on the motor.
In the end, your thoughts on the cams are not wrong. They will make more power. I personally just think people will be more happy spending their money on a good set of aftermarket cams. Key word there being GOOD. There are plenty of shitball cams on the market that do ruin cylinder heads, break timing chains, tensioners, are not VTC safe ect. Just remember that not all cams are made to the same standards, and for sure have VERY different design philosophies behind them.
I am not trying to argue with you just to argue. I just want to voice my opinion
, with my reasons behind it so people will have more information to base their own choices on.
