DIY : Install underdrive pulley on 2010 Camaro SS

[jmlozano7]

Do not use the 82.7" serpentine belt that they tell you. It is too loose. I spent over 3 hours installing the thing just because I had to go back and forth to O'Riley's to get the right size. I ended up buying the next length below to get the correct tension. Don't have the part number at hand but it was a Gates belt close to 81.8"

I worked for several hours to incorrectly remove the pulley to discover that there are indentions on the back side of the hub. Once I used these indentions and a push rod that was long enough, the stock pulley came right off. There is a "seal" that is on the lip of the stock pulley but does not fit on the TSP replacement pulley that I installed, nor is it required.

Wouldn't changing the pulley void the car's warranty?

The "car" no but they might make a case for not supporting any of the accessories driven by that belt.

Yeah. But, why do any of that when you can sell an overpriced product (in Canada anyway, Americans are getting great deal on these rides), make all kind of profits, make the new owner spend thousands on aftermarket mods so the vehicle performs the way it should, and now (GM) can dis-honour the warranty. Works great in their favour. Right?

Not sure about the US but I paid $53k for a Camaro SS / RS (stripes, IOM, GFX), plus $10k in engine / suspension upgrades (CAM, rods, dual springs, ceramic covered headers, complete new exhaust, rockers, cai, springs, end-links, swaybar, chassis & strut braces, labour, etc......). And, I got a fabulous deal on the car, parts and labour.

Would have been fabulous if GM engineers would have realized they could have given us 200+ additional HP's by putting on some good parts.
Hey, even throw in a Maggie SC (instead of the crappy one they'll provide with the Z28), boosta a'boost, fuel pumps, meth kit, and maybe some higher flowing headers, and stroked the engine all for another 175 - 250 more hps's.

Problem, is people will pay $80 - 100+k, for a BMW or Mercedes and have much less vehicle, but will complain if they had to pay $60-70k for a superior GM product with all the fixings.

I'm with you; People like to make dumb comments about how GM used the best parts and so on when in reality GM put the parts that would work at minimum spec. so they could make a substantial profit on these vehicles and still provide better value than most other vehicles in the same or higher price range, and people will realize that value and pay the price their asking. Really, in the case of the Camaro it's a win-win for everyone.

Currenlty, I have 470rwhp., add on a new pulley +10, new heads +20 - 40, new SC 150 - 200, new gears faster accelleration, et al. It all adds up, and if done properly with a good tuner, works just fine. So, for about $70; I'll have about 600rwhp., and no BMW, Mercedes, Porsche, Jaguar, or any other EuroTrash overpriced tin can could even think about overperforming my car on the street or track; Um, okay, unless of course it costs $300k or more. Suckers. LOL

People won't pay $200 + labour for a new pulley, but they'll pay $120k for a Nissan GTR, and break the entire drive-train when taking off in launch mode.

I was told installing a smaller underdrive pulley is a terrible idea, due to the fact it effects your power steering, AC, alternator, etc etc. They all get less attention due to the fact the underdrive pulley provides less in a single rotation

T/F?

[chriscamaro69z28]

seriously if the pulley was a problem then why does the zl models from SLP come with them and GM offers a full factory warranty on them. My buddy has the ZL427 with SLP mods which includes the underdrive pulley and is fully warantied by GM as he bought new from the chevy dealer so i cant see the pulley being a problem im installing one on my car this weekend and i ran 1 on my 01 ss camaro with no problems

You're going to need more than 600whp to take on a Porsche 911 gt2 RS buddy.

[immaculate chaos]

Anybody here have any experience with removing the power steering pump on the 5th gen?

Do you know what can be done to a Camaro SS with $200k (euros) in upgrades? Let's not even go there.
It's always been quite rediculous that euro's have to spend 5-10x more to get a eurotrash to compete with an inexpensive domestic musclecar, and they still break up on the track. Am I supposed to be impressed by that?
