S&S Diesel Motorsport 12MM Injection Pump CP3 01-10 GM 6.6L DuramaxSo, the guy down the street hit 1000hp and now you want to too. Anytime we get bit by the power bug, we have to react right? A critical component of high horse power is proper fueling. Where your stock CP3 is good to about 500hp, the S&S 12mm CP3 is good to double that. You got it friend, up to 1100 hp (with supporting modifications of course). As you start pushing the factory CP3, you see that the output really flattens out like a hashbrown patty
So, the guy down the street hit 1000hp and now you want to too. Anytime we get bit by the power bug, we have to react right? A critical component of high horse power is proper fueling. Where your stock CP3 is good to about 500hp, the S&S 12mm CP3 is good to double that. You got it friend, up to 1100 hp (with supporting modifications of course).
As you start pushing the factory CP3, you see that the output really flattens out like a hashbrown patty around 3,500rpm. For towing, more diverse terrain, or racing, that's not gonna cut the butter. The 12mm from S&S will reliably keep feeding you the fuel you need clear up to 5,000rpm, or even higher (roughly 500rpm more) with the High Speed 12mm. That said, this pump will crank 7,000rpm, though only INTERMITTENTLY.
Then, there's SP3000 Supply Pump for you crazy people that want even more power.
What Is the SP3000 Supply Pump?
The
SP3000 is a high-performance single mechanical pump engineered to
replace factory supply pumps in diesel fuel systems, offering impressive
flow rates and pressure maintenance for demanding applications. With a
flow rate of up to 3,000 liters per hour and a maximum pressure rating
of 400-psi, it ensures consistent fuel delivery even under heavy loads
or high power conditions. Constructed from durable aluminum and steel,
weighing in only at 1,271 grams, it offers a reliable and
corrosion-resistant finish. Acting like an in-line lift pump, you can tie in 3 CP3's and if they're all 12mm, you can provide fuel support for up to 3200hp. Please make sure everything on your build will handle it first.
Obviously, the SP3000 provides a robust and efficient solution for upgrading
diesel fuel delivery systems facing demanding performance and power requirements. Lucky for you, they're an option ready and waiting thanks to our friends at S&S Diesel Motorsport.

Excellent!!
Color: Beige, Size: Large
Really loved these shirts for my hubby. They were pretty good quality shirts. Love the linen material. Also love the buttons on the collar which my husband prefers to wear with his jackets. They are very comfortable. As far as size, I ordered according to the size chart. He typically wears a size Large. According to the size chart an XL would best so that’s what I ordered. But I truly believe that a size L would’ve been better. So I would say they are true to size. My husband weighs 205, and has muscles and a size L would’ve been just fine. I ordered 3 because I loved them. I’ll stay with the XL. But if I were to order more I’ll preorder a Large. Very happy with this purchase. They are not slim fit either. Just for an FYI.

Quality + Fit + Value - VERY pleasantly surprised!
Color: Black, Size: Large
I stand at 6.0125" 200lb (showing signs of a Dad bod)., and the large was a perfect fit for me. The quality exceeded expectations, perfect thickness and weight for the colder months. I actually set this up between a Boss & Ted Baker (my-go's to in past 10-years) and asked my date to pick one of three - she grabbed this shirt.
if you're looking to re-evaluate how much your spend on dress shirts - this Brand will not disappoint in terms of quality and fit. If your wearing brands like Express, Banana or even worse - Untuck-it, consider this a marginal upgrade.
I'm going to by a few more and I'll update if anything changes.

Great shirt
Color: Beige, Size: Medium
Great fit, seemed like thin to medium weight fabric which is perfect for him. Lil with any linen blends, they wrinkle so it is more of a casual wear. Washes great and is super soft when wearing.

Trashed after one wash
Color: Beige, Size: Small
It’s a great looking shirt. The price is good. The fit is good. But it’s so scratchy that it’s like wearing a potato sack. And after washing it ONCE it pilled so bad that I had to throw it away because it looked like an electrical sander had been used on it. But this is what Amazon has become: bad quality everything.
