i posted a thread last week on which supercharger to go with and it looks like its going to be ECS with possibly a meth kit. the car is a LS2 6 speed with HCI, full 102mm setup , pfadt Lt's borla ATAK , Zo6 fuel pump with holley EFI rails and injectors . i only drive the car maybe 2 days a week at max typically just the weekend . But i DO NOT want to lose reliability whatsoever and wanna squeeze a lot of power out of her.

The Question is should i get the 1500 kit and stick to around 9-10 psi or get the 2200 kit and run that at 10 psi? to my understanding the 2200 will make a lot more power at the same PSI compared to the 1500 kit with the same or less stress on the motor . Any insight will be much appreciated thank you

1500 is good for 850rwhp

If you aren't going for more than that, 1500

I went with the 2200 because I got it for a great price. Im almost done with my build and will let you know my results.

1500 is fine.

if your goal is 850 or less rwhp do the 1500, it will be in it's efficiency range and have a much better low/mid range than a big head unit run slower to make that same peak power.

My goal will be 700-750 RWHP but again im on a stock internals motor . The car only has 50k on it and everything is new except the rotating assembly. From what im reading to make 750-850 i would have to be spinning that 1500 really hard and stressing the hell out of it generating a lot more heat at the motor for being at 15 or so psi is this true? I heard running the 2200 at 6 psi is equivalent to running the 1500 at like 10-11 so i assumed getting a bigger unit to like 9-10 i would be similar to the 15 psi on a small head unit. Im just trying to be as "safe" as i can bc the car will still be a true "daily driver" . My biggest question is will running a 2200 at 9-10 psi be just as safe as running a 1500 at 9-10 psi?

You've been told by one of the better shops out there what to do. If you're dead set on getting the 2220 then quit asking what we think.

Dyekid04

I seen what Joe said and I definitely took that into consideration, i just want to make it known i do not plan on turning the centri past 11 psi . So which kit would benefit me more at that psi or lower ? I understand i can make more than my current RWHP goal with the 1500 series. But to achieve that it seems i would be stressing the whole setup would i not? Im trying to make as much power with as less harm and stress on the motor as possible. With that being said what setup doesthat leave me with?

With a stock ls2 and a 1500 . What type of motor build would you need to get to that 800-850?

Plenty have been running the 1500 for years without any issues. Running them with a 3.25" pulley is pretty much how ECS ships them.. there aren't many failures.

The problem is the only way you can keep boost down on the 2200 is to use a big pulley or smaller pulley + restrictor plate. Big pulley is going to make it sluggish at low/mid RPM's and a restrictor is going to make IAT's go through the roof. They don't work well on larger blowers.

I still think your best bet is to run the 1500, put a 3.25" pulley on it and use a restrictor plate to limit top end boost as needed. You can always open it up or remove it to increase top end boost/power if needed.

Not to mention with a 2200 you're probably going to need more than a standard 6 rib belt setup, so there are some extra expenses / PITA to deal with there as well. 1500 is really reliable and simple. I'd stick with it.

schpenxel

Not much. People have done it on stock bottom ends, though LS3's seem to survive at that power level better for whatever reason.

If I were doing a build for 800rwhp I'd just change to some nice pistons/rods, leave the stock crank, add a blower cam, and that would be it.

And it goes without saying you need enough fuel/octane to run that much power. Either through a good bit of meth or with E85 and a flex fuel sensor, or both even.

No reason to make it complicated though IMO

I just made 771/654 on 12psi 2009 auto car with a 1500. Btr cam, kooks headers and meth.

Thats bc mike is a guru over there! Lol

I went with the 1500 because even though the 2200 makes more at the same boost it's not going to make more power under the curve. I knew I was capping around 750-800 so it made no sense to go bigger.

My biggest annoyance with the 1500 on a 3.25" for me is that it's on a 6 rib. If I had to do it over I'd go 10 rib from jump. 6 ribs don't like 14psi much

I'm on E and I'm a bit over 700 without a cam and 14° of timing in.

1500 all day unless you want 900. 1500 is in its happy spot at 800.

DOUG @ ECS

The only thing that would lean me towards the 2200 would be if you get it oil fed. Mind you I am talking about the 2200, not the 2200R (YSI)

That blower is only a little bit bigger then the 1500 so the low end is not effected as much and you have room to grow down the line if you wish.

I consider the oil fed units more durable, and they have a higher red line. Many oppose tapping the pan though.

MBB

I went self contained to purposefully avoid tapping my oil pan because if I were going to go through that trouble I'd have gone turbo.

neverstop

I'd bet the 1500 will have better torque curve and more power under the curve than a bigger head unit spun slowly

silas1234

No doubt very good time down at vengence. It made about a 100 more then we both thought it would make. The 1500 is no joke.

realcanuk

Tapping the pan is no big deal while you are doing the install.
