High 700s to the wheels on pump gas with absolutely no cooling issues at all sure does sound amazing.

I did a full build on my ZL1 and I would do it all over again if I had to. At idle that cam sounds menacing. The whoosh from the blower at even just partial throttle sounds insane. There is nothing like it. Sure you can duplicate those numbers with porting and E85 on the stock LT4 blower and yada yada. But I bet you, put it next to a full build making the same power and there will be a huge difference. I could never try to stretch a supercharged engine/setup to it's limit and feel comfortable. You'll be beating that blower to within an inch of it's life and using every trick in the book to make the same power that the 2650 will easily make on a basic tune with pump gas. So why even bother with the stock blower?

Yea but this where I've got to disagree. I've been there and done that with my previous Hellcat and said I wouldn't do it again. I understand MOST people do eventually keep modding their cars until it gets to be too expensive or breaks all the time. My Hellcat was over 1000hp, I got tied up chasing HP numbers and before it was over realized I built a race car that couldn't be enjoyed on the street anymore. I don't want to go that route with the ZL1. At times I think I want a cam for the lope, and if I eventually go that route, I may upgrade to a 2650R but for now, it seems there's VERY little to be gained from it at this power level without more fuel.

But you do understand that you're chasing HP numbers now, right? That's my first point I'm trying to make.

The second point, you're going to go to extremes trying to make a setup push a certain number that can be easily achieved by just going the more efficient route. In a way, when you really look at it, modding the stock LT4 blower is more similar to what you did with the HC. You're trying to push and extract it to it's max. E85. Kong stage 28 port job, this and that and the other. And end of the day it still won't be as efficient as just going with a better blower which will safely and easily make your desired numbers on pump gas alone.

And lastly is peace of mind. The bigger blower will give you fool-proof, worry-free, no-nonsense power and not break a sweat. Seems to me that is the way to go. No worrying about blends and overspinning the blower and heat issues etc.

End of the day it is your car, your money, and your choice. But when you're strapped at 700 RWHP and see others making much more than that on an easy and relaxed setup you will want more. SUre you had a 1000 RWHP Hellcat. But the ZL1 is a completely different animal altogether. My HC make 766 RWHP and my ZL1 makes 745 RWHP and I'll tell you, the ZL1 is a much meaner machine. I am almost certain that you will not be satisfied at 700 to the wheels when a lot of us are making more than that easily and on just pump gas.

callaway is the only company that GM is giving access to the new C8s computers so far.

Is he the guy from Fuel Tech with the twin turbo? Not sure but I figured at some point Magnuson would build one and somebody would figure it out how to get there. Others are running turbos plus Procharger is now offering one so I figured Magnuson would be the first PD to get there since Whipple has dropped their Lt1/4 blowers for now I doubt they'd do it.

You can't tune the C8 through the factory ECU...Unless things have changed recently anybody making power with them are using piggy back systems which cause random issues with the other controllers in the system. The stock clutches also don't hold shit for power. We have already seen time and time again that just because a company makes a "kit" doesn't mean it's right. Anything from GM with Global B communication is screwed unfortunately. That doesn't mean you can not hack a car up to go run a track number...I am talking modifying the car without compromising any reliability or dependability.

Yes he's in Houston and developed the setup for Emilia Hartford's TT and now is selling the fueling systems. He's probably one the best tuners around he's really good at explaining what he's doing to your car and takes a lot time w each customer. I had him tune my 5 th gen then he moved to Florida for a bit to run the HPtunimg school then came back to Houston just after I got my zl1.

It's supposed 5o be unbreakable but so was the zr1

Time will tell, figured EBrock was also working on one also. They have to keep up with the trends and can't let anyone get to far ahead. Did you see her in the Z06 Live video. I've watched her run her twin turbo and she's almost in the 8s with it and the guy from FuelTech went 8.97 so the piggy back is working good enough for drag racing but those C8's really aren't street worthy.

Nope nothing has changed only the piggy backing is the option for now. When I worked for Magnuson it was pretty common for the guys running the Tundra's to piggy back off the ECU until we brought out a new tune. They were installing the blowers from earlier Tundra's since they really didn't change much for years and sometimes a lot of issues arose when doing that. Can't remember the name of the company building that system but at the time they were the only ones doing the piggy backs.

[KingLT1]

Exactly so it's a waste of time from a reliability stand point to even try and modify a C8...anybody in the know that bought one sold it and moved on. Even with a piggy back controller you still can't make any power without changing the clutches in the DCT. Even then you still are likely going to burn up aftermarket clutches without being able to get into the trans tune. No different then trying to make big power on a stock A8 or A10 tune.... Shift pressures need increased to add clamping force on the clutches so they don't slip on shifts.

There are a lot of smart people in this performance world so never say never.

HPTuner's things have a way of changing sooner or later

I'm not chasing numbers, I'm at 700whp which is where I want to be. I asked about the 2650R to see if it would make my setup more consistent.

All one has to do is follow Emilia Hartford's journey in her C8 to see all the hurdles they had to overcome. Just about everything has broken on that car and been upgraded or replaced.

I do agree with this statement also. There's always a new challenge every so many years and people say this can't possibly be cracked or overcome and yet, it seems to always find a way. It may take quite a while but it always seems to happen eventually.

[EDFHOBBIES]

A 7000 dollar LT2 blower and 2200k to send the ecu to Hptuners so you can tune it plus a 750 tuning fee not even worth developing unless it bolts up allready and it just a snout you have to develop. Remember those are Zr1 price probably tach on another 1k to 1500.
