Gt500 SC on s550

[sqidd]

Seems to me like one could prolly boost their s550 for not much more that $5500, unless you want and upgraded aftermarket gt500 unit

With a little small fab type operations so GT500 parts can be used for the intercooler system and CAI it could be done for $3900. With new S550 intercooler system parts it can be done for $4800-5000.

Looks like a bargain kit! Stage 3 gets you the kit plus everything you need to Install it Minus the $500 PITA kit. Doesn't seem too bad for around $5k. Does anyone know if they're still selling this kit?

I've worked with DOB and had them make me some pretty trick parts over the years. I see a DOB S550 kit in my future....

First post on this site here, but I contacted Jason at Department of Boost and he said they are not yet selling complete kits and might not. He did send me a list of the parts I would need to complete it myself however.

rjmcfarland is correct, there won't be any Phase III kits until next year.

But there are Phase I "Hot Rod" kits that can be used to build up your own complete kit. This can be done for a total of $3900-5000 depending on options/parts chosen.

The web site needs some updating.

So, say a person was to buy the kit or parts that are available to install this. Would the car be drive able, as in could I start it up and drive it down to my local tuner for him to work with? Guessing the factory tune might not allow the engine to run good enough with these parts installed?

The M122 is VERY “happy” making 550rwhp on a Coyote. And it remains happy all the way up to about 610rwhp. You could spend more money and run a 2.3L TVS, 2.3L Whipple, 2.3L Edelbrock, 2.8L Kenne Bell, etc. and at 550rwhp (the effective octane limit of the Coyote, more on that here) won’t see any measurable performance advantage over the M122. So who wins? The guy who spent less money and went with the M122? Or the guy who went with the other ones? We say the guy making the same 550rwhp with no sacrifices for less money…..wins.

There is a horsepower level where the M122 won’t be big enough and getting into something else is the smart move. But 95% of people never go for that kind of power. And for those that do at some point can put anything from a 2.3L TVS to a 4.5L Whipple right on the GT550-S197 manifold. No need to get a completely different kit.

550rwhp is the limit of the coyote huh?

95% of us don't go for more than that power?

Was this post from 10 years ago lol?

The octane limit, not the limit of the hard parts. On a stone stock motor with stone stock exhaust running a safe tune and not spinning it past it's redline and at full operating temp.............................yes.

If you want to:

-Use big exhaust/headers.

-Run more than 10.5psi and lean on the computer to de-rate it when it's at operating temp.

-Run an aggressive tune that will have more timing on the dyno but de-rate on the street.

-Spin it's guts out.

-Etc

.....you can show all sorts of power on a dyno graph. I deal in stone stock numbers with runs made at full operating temp without any tricks to show more power though. Some don't.

Or just get a start up/drive tune from your tuner. But the short answer is yes, you can drive it without it being completely tuned.

Or do remote tuning with Lund and never visit the dyno.

Out there in internet land the stock 07-12 blowers (2.0L Eaton M122’s) are commonly referred to as “Heat-ons” because highly modded GT500’s that are still running M122’s have high intake air temperature (IAT) problems. The high IAT problem in this situation is because of many factors. Yes, the M122 is not as efficient at compressing air as let’s say a Twin Screw blower (a Whipple for example). But the M122 is not a horrible blower by any means. When the GT500 crowd goes looking for more power out of their stock M122 they start by speeding it up…….a lot. On a stock GT500 the M122 spins at 15,625rpm which is right in its “sweet spot” and it doesn’t make a ton of heat. When the GT500 guys go for big power out of the M122 they first bump it up using a smaller upper pulley to 18,750rpm, which is not in its sweet spot anymore. And it really starts to make some heat. The next step is to add a 10% overdrive lower pulley which spins the blower at 19,875rpm. Now they’re making a lot of heat. The next step after that is to run a 15% overdrive lower pulley which spins the blower at 20,325rpm. Which makes a TON of heat. And all of those blower speeds are based on them not spinning the motor past 6,250rpm. If they raise the motors rev limit (most do) the blower spins even faster. There are guys out there spinning their stock M122 at 23,000rpm!!!! Some of these guys are spinning their M122’s 50% over their “sweet spot”. It’s no surprise that they don’t perform very well and produce a lot of heat. Complaining about a blower spinning nearly 50% faster than its sweet spot and making a ton of heat is like spinning your motor to 9,000rpm and complaining when parts come flying out of it.

Yep.

Guess I should have worded it better: The stock GT500 blowers can be incredible heat generators....



I know mine was when pullied, as described.

Another reason the "Heat-Ons" are an issue on the GT500 is that the GT500 intercooler is not very good. You get a completely different result when you plop a M122 on the best intercooler in the industry, the GT550 manifold/intercooler. Even if you do over-spin it.

And people can always put a TVS or twin screw on the GT550. They don't have to run the M122.

I really want to build one of these kits for my car. So you do have the stage 1 kits available Jason? Haven't seen many people talking about the GT550 kits in the wild.

Same as the S197 kit.

What is the estimated weight of this setup running M122? I know the Whipple setup adds ~100lbs on the front of the S550.
