CT5-V Time to mod...

[Savethemanuals]

Keep hearing good things about vengeance. Will be my choice of shop when I’m ready to mod. I’m not too far from them either. Look forward to reading how yours turns out.

VR is not cheap but they're work is impeccable and surprisingly, there are quite a few things that are needed to go with a build like that most people probably don't factor in. But to answer your question, its roughly $23k, I chose to have the car tuned instead of letting the stock ECM adjust for the mods. I was told by VR that the stock ECM does a good job of adjusting for a lot of mods due to the global B architecture and I could have installed the blower and ran it that way without issues, but tuning the ECM would optimize it even further so the tuning was roughly $3400 by itself to unlock the ECM, dyno time, and HP tuners credits, plus the cost of the actual tune.

Very interesting build. I’m looking to get both the heat exchanger, tank, maggy, a proper breather, but I’d like to stay on the stock tune.
Do you think I should just get a cam, high pressure pump and a tune while I’m at it?

Btw, 23k is cheap. I’m 100+ into a mkiv, parts labor alone

You're giving up a lot of power staying with the stock tune especially if you increase the boost level which the stock Magnuson 2650 pulley will do. There's at least 30-40whp more to be gained from tuning it with a 2650. Without a tune you're looking at maybe 60whp, with a tune around 100whp with no other changes. If you think you're going to want more than 700whp then, you will need more high side fueling which means you would need either a cam, high flow high pressure pump and injectors, and you will need some low side fueling assistance too, problem is that no one makes a drop in dual fuel pump kit for these cars right now. Some shops will build a custom dual fuel pump but there is no off the shelf kit right now. DSX makes an inline fuel pump which will help go a bit further than the stock fuel pump but eventually you will need dual fuel pumps. The other option for high side fueling is port injection, DSX and TooHighPsi both make port injection and honestly, I would go that route over a cam because it has more fueling potential in the long run. If you go with a cam, you're going to need a tune anyway.

It's almost done now.

Thank you kindly for the detailed explanation.
What your take on the whipple vs the 2650?

My sc300 makes 790 on waste gate, and around 1300 on 55 psi. So chasing power with the caddy may be futile.
I absolutely love this caddy, it’s my daily, I was thinking oem+ without porting because of the heat. I’ve had a ported blowers before, the bottom end tq loss and the heat is not worth it in my opinion

Btw, your V is savage!!

Whipple blowers aren't reliable, and they just aren't as efficient as the Magnuson 2650. End of story really.

The Blackwing is very capable of making 1300hp, but I agree, not sure why you would want two cars making that level of power. 700whp is a good number on these cars for street tires as long as you're in a warm environment. Anything more than that and drag radials become a necessity.

It's certainly cheaper to port the OEM blower and use a lower pulley but you're going to have to add a lot of additional cooling mods for the blower and even then, it will still run hotter than a Magnuson 2650 with no cooling mods. You won't lose any torque on the stock blower if you go with a Kong standard port and lower pulley. The Kong X-Port will give up some torque below 4k rpms but some people claim its hardly noticeable. I had a 2021 Camaro ZL1 before my Blackwing and it made 700whp with a Kong ported blower (Not X-port) and 9.45 lower pulley, 103mm throttle body, 2" headers and high flow cats, and supporting cooling mods for the blower. I never felt any loss of torque with the standard Kong port but they don't remove nearly as much material on the standard port vs the X-port.

Here's another pic without the blower lid. You can see how much larger the 2650 cooling bricks are compared to the stock blower.

Extremely useful info, thank you kindly

Last question please,
If I went with the 2650, would I need any extra cooling mods? Is it necessary?
I don’t want e85, nor meth. Just pump for this one
I’d love to get the maggy, proper fueling and catch can. Call it a day

I popped the blower lid open to see what’s what, the bricks looked small, and while I was there, I removed the three plates. Week later I got a mpi lid and k&n intake
I already have two sets of wheels for the V, 3 sets of sticky tires ready
Switched to Hpl 5/40 and I cut the filer open every 3k to inspect, on all my cars

Again, thank you!

No extra cooling is necessary with the Magnuson 2650, at least with the stock 90mm pulley. If you really start to push the blower up into the 18-20+ psi range, it wouldn't hurt to have more cooling capacity.

What you stated is basically what I'm doing to get it as close to 700whp without needing headers and high flow cats. Magnuson 2650 blower, JLT 5" intake, 103mm throttle body, DSX aux fuel pump and Mighty Mouse Wild catch can, and ECM tune. It's pretty obvious how badly direct injections cars and really all forced induction cars need a catch can, look at the pic above of my stock blower with 9K miles on it. There's quite a bit of oil in there.
