This is quite a decent improvement. The cam swap increased the peak power output from 383 hp to 448 hp a gain of 65 hp but out at 6300 rpm the Hemi Helper offered an additional 100 hp.

The performance improvement can come from two types of change.

. Our stock 57L heads had been previously upgraded with 26918 Beehive springs from COMP Cams so they were ready for the new cam profile. You get the drift. How can camshafts be optimized for maximum horsepower.

Camshaft 2 has excellent top-end horsepower. Is just a camshaft whose lobe profile is tailored to utilize more of an engines potential. What techniques do engineers use to design a camsh.

The basic cam lobe. The split at 5800 rpm was 345 vs 310 rwhp. The engine should start quickly and be run between 1500 to 3000 rpm.

You can expect up to 50-100 more HP with a good. Some thoughts on choosing the proper cam. The bottom line is.

Stock engine with aftermarket cam and 4 bbl intake and carb 295 Hp. Vary the rpm up and down in this rpm range for 20 minutes. Its a sound strategy as installing a performance camshaft is proven to increase horsepower but the real question is just how much power does it add.

The base engine was a time-tested 350cid 290 horsepower small block GM crate engine featuring a Weiand Air Strike intake manifold 650cfm Holley carb Hedman 1 ¾-inch primary tube headers Magnum mufflers with. Peak-horsepower improvements were actually even more impressive with a 70hp gain at 6200 rpm. It translates to better fuel efficiency and an overall better driving experience.

Not usually a preferable combination in 2 bbl classes Short duration cams with wider lobe separations usually yield much flatter torque curves. During break-in verify that the pushrods are rotating as. Fox Body cams not only add performance but they also give your Mustang an aggressive lope exhaust tone.

It will also work well with the stock converter and compression. Intake Centerline duration 2 IO Intake Centerline 274 2 31 106. Camshaft 1 will have plenty of low and mid-range torque.

Sometimes with a very mild or stock cam the IO occurs after TDC ATDC. In other words it wont sound like a Harley Davidson at idle. On race turbo engines running high boost weve seen around 400bhp per litre running similarly mild cams.

For a well-tuned system the exhaust pulse can be super effective over as much as 4000 rpm. But to make all this work as intended the cam must generate the right events around TDC. The following tests were run with the COMP Cams new Flat tappet Thumpr camshaft on the Westech dyno over three days in late December.

If you want to know about HP then the engine will be able to output 320 HP after the install of this camshaft. One dyno test showed that a stock cam 218 degrees duration produced the same peak horsepower and up to 15 more midrange power. We did the math and came up with a staggering average increase of 46 lb-ft of torque.

Stock engine with the desired aftermarket cam 275 HP. Since that is not a real hairy cam its ground to work well with your stock components so you should see some significant increases from it even without any. We also upgraded the pushrods during the cam swap.

The midrange power is extremely important for driveability with only two forward gears. This Mustang X 303 Cam offers an aggressive idle with excellent torque and horsepower gains up to 6200RPMs for your 302 Fox Body engine. There are many engine characteristics which will effect your camshaft selection so there is no single best camshaft.

Longer duration cams require tighter lobe separation to have any power off the corner. As a general rule of thumb up to 265 degrees gives a good balance of extra power and maintains smooth running and is most suited to a standard engine. How much horsepower does a camshaft add.

Check for the cause of the problem and correct it. Camshafts that are specifically created to boost performance can significantly boost your engines horsepower. The often-quoted 50-100 horsepower gain is only possible with a series of accompanying.

Orders Only 800 426-2261. With no other changes the cam swap improved the peak power output by 108 hp with even greater gains coming at higher engine speeds. They do this by changing the timing of the valve and increasing the duration that it is open thus giving the engine more horsepower and quicker acceleration.

Can you increase horsepower with a better camshaft. With your average four valve per cylinder engine you can usually get well over 200bhp per litre on pump fuel with relatively mild cams around 260 duration which keeps the car tractable and responsive low down. In this case just add the IO figure to half of the duration.

This test is a perfect example of what happens when you add a cam to a motor that needs only cam timing. Most noticable is the fact that the Hp peak for the stock cam came at 5300 rpm 320 rwhp and by 5800 rpm the hp had declined to approximately 315 rwhp. Stock engine with stock cam and 4 bbl intake and carb 265 HP.

While its true that camshaft adds horsepower its only 10-20 horsepower and generally less than a 10 increase. The new cam made 340 rwhp at 5300 rpm peaked at 346 rwhp at 5700 rpm and was still making 338 rwhp at fuel shut off at 6200 rpm. A good exhaust system is worth a lot of extra torque horsepower and best of all extra mileage.

Usually a higher lift on the lobe which increases in length of the valve stroke which allows for more air to. Run with the stock cam the 57L Hemi produced 367 hp and 414 lb-ft of torque. Good power up top.

An average family car will typically have a cam duration of 250 degrees or lower. After installation of the cam the 53L responded with peak power numbers of 467 hp at 6600 rpm and 418 lb-ft of torque at 4900 rpm. However it requires at least 1051 compression a 3500 stall converter and rear-end gears to get the best performance.
