We're proud to announce that we now have the Texas Speed & Performance 2010 Camaro SS underdrive pulley kits in stock & ready to ship!

This complete underdrive pulley kit features a 2010 Camaro SS underdrive pulley, new AC belt, new serpentine belt, and crankshaft bolt.

The TSP pulley kit has been designed so that you can bolt the package on in your garage with no lift or special tools!

The test car was a stock M6 car with only a catback. Pull 16 was stock with the Rumbler 5 catback, pull 19s only change was the pulley install!

Dyno results show 9hp & 8tq just by bolting on this kit!

I have never heard of this type of technology for gaining HP. How does it do it?

Parasitic Drag

A smaller pulley lightens the load on the engine. It will drive the accessories slower, which can reduce the battery charge and cause issues for those with bigger amplifiers, drive the AC compressor to be less efficient, and slow the water pump. The trick for the designer / manufacturer is to pick a ratio that doesn't adversely impact the performance of these devices.

In the end, your engine spends more energy driving the rear wheels.
You'll notice your car is slower with the AC on, because the compressor is engaged - cooling your cabin, this is parasitic drag.

do you also make a compensation pulley for the alternator?

Did that mod on my 2000 Z28 and gained 11rwh .That crank pulley bolt is special and is torque to yield.It can only be used once.

wouldn't that defeat the point?

Anyway, in my opinion this type of Cheap HP is kinda dangerous. Everything that is connected to that pulley was designed to run with the factory pulley. You are no doubt going to lessen the life of everything connected to the belt because it has to run harder. I know modifications are made to the engine all the time that increase hp and make the engine run differently to get those gains; however, your engine has sensors everywhere to make it run differently to compensate for those changes so everything runs nice and dandy. Nothing connected to the belts, except for the engine of course, has any type of sensor to help it self adjust to the changes so you are inevitably going to shorten the parts life.


Just my opinion though...

not really. you still underdrive the rest of the accessories, but you get the original amperage from the alternator.

The Amprege is not a factor on vehicles where the alternator is not driving huge Stereo's with numerous amps and subwoofers. Would not do it on that kind of vehicle. Otherwise it is invisable to normal weather and driving.

watch out for underdrive balancer pulley's for LS engines, they like to tear up timing chains!, do a search on ls1tech.com

Actually, just the opposite. The alternator is constantly turning on and off based on the demand of the electrical system and if it is spinning slower it puts out less power, nothing really is harmed. In the case of the water pump it just moves water more slowly, overheating could be an issue but not really wearing the parts out from moving slower. I'm not real sure how the A/C comp. works but I would wager it is similar, where it sees the engine speed as slower and in normal driving does not see any real difference. The only time any of these will see any drop would be at idle, not while driving since it may look like idle to the acc. but that is still within the operating spec.

How many "muscle heads" will cross the line into "ricer" territory.
Yall know budweiser is made with rice, right?

Come on in, the water's fine.
Bob, real muscle heads will do anything to get a little more power, that means turbos, front mount intercoolers, blowoff valves, fuel management computer, ect. The camaro already has an electric fan i think. A lightened fly wheel lowers rotational mass and so on. Calling anything that actually adds power "rice" is just plane stupid and ignorant. Some guys like N/A, some like S/C's and some like turbos. Are you going to call me a "ricer" because I have a light weight drive shaft??? "Rice" only comes into play with looks and fart cans, in my honest opinion. Many people have underdrive pulleys in many different types of vehicles, including trucks, they dont have any issues. So why call a legit power modifier (you aren't adding power w/ an underdrive pulley, just freeing the power thats already there) rice?

And contrary to popular belief, stickers don't add horse power.

I'm not crazy about this particular mod but calling something "rice" or otherwise mocking mods that actually add rwhp is ridiculous.

Underdrive pulleys are far from a new concept for imports or even muscle. And several years ago, underdrive pullies could lead to battery charge issues, and cooling issues, especially if you found yourself idling during a hot afternoon communte.

However, I think these days most cars are installed with alternators that have sufficient capacity.

Other issues are engine harmonics in that the crank pulley needs to meet specific balance requirements so the crankshaft is spinning correctly, but again....if the pulley is up to SFI standards, all is well.

Too much of a risk for such a small gain.. Adding a K&N filter will give you a boost in HP too and is less harmful a mod..

what if you plan on spinning a supercharger with the main drive belt? Will we be able to find the right length belt, and hopefully the FI manufacture has the right size pulley to compensate. Has anyone gone the forced induction route with a undersized pulley?

Don't do it, there is no need for one with F/I....and actually in some instances, people run OVERsized pulleys when running a forced induction build.
