What would be the next best bang for the buck bolt on wise? Ported intake, Axle back, Secondary cat delete, etc?

I know you said bang for the buck and bolt on but since you have a ProCharger it would be really nice to get to that intake off.... Then if you get to that intake you might as well start to address the HPFP and injectors while you're there. Then some would say..."hey might as well tackle those heads, valves, and springs while you're there". Ok disregard everything I just said.... really goes against your initial post.


Doing headers and exhaust was my favorite next move from FI and I really really liked it. Now it sounds awesome as to just being fast. No real noticeable gains though if you ask me. I would also consider this next thing since it is also my next move, getting HP-Tuner professional w/ Microsoft laptop to data log and learn what my car is doing and how to improve it. I've noticed that these are cars and very very touchy on the tuning side. I believe tuners are still learning these engines w/ DI. Then again I'm a bit of a control freak and like to see the data for myself.

I had a similar question that Ted from Jannetty answered for me which makes sense. In short he said something along the lines of "the only thing you're going to get out of doing TB, intake, etc is a lighter wallet. The Procharger doesn't care. It's forcing air through regardless"

The "next" thing to do if you want more power gains after the supercharger would probably be to upgrade your fuel setup. I would start with the ZL1 in tank pump (around $200 I think?). Followed by the LT4 high pressure mechanical pump and LT4 injectors. ($1500ish). All of this is pretty labor intensive too. Once done though you can increase boost a little and have the fuel to handle it. You could also run meth, but I have not educated myself on it enough to give you a recommendation on it.

As said above though, maybe your next step would be exhaust. It will sound awesome and it will needed at some point if you keep wanting to add power. Just keep in mind once you start creeping toward the 650whp mark I have read you're going to want to start thing about rods/pistons. As for the intake, you won't get any noticeable power from it. (It does look sweet though.)

My personal goal now is going to be to hopefully install my procharger next week, get some bigger rims and tires, then do the in tank pump and look into a slightly smaller pulley, then have Ted tune it down in Connecticut.


Good look, be sure to post your results!

Thanks for the info guys!. This really helps me out a lot!. Based on some of your comments I wanted to ask.

Exhaust - Axle back or catback?

ZL1 in tank Pump - Will adding this just increase fuel rail pressure and NOT require any re-tuning?

HP Tuner Pro - I really want to be able to datalog and man it would be nice if I had the ability to share that with others and be able to make minor tweaks here and there. I have a 2017. Does anyone know exactly what I would need to do this? Is there a link to a package deal on the software/hardware needed?

Thanks guys!

How much power do you want to make? Get a handle on your goal and this discussion becomes easy. No need to just buy parts if you don't need them. Or worse, buy parts and have to throw them away because they weren't a good matchup.

You may not even need a ZL1 fuel pump if goal is around 600 rwhp. Depends on the skill of your tuner and the luck of the draw on the ability of your particular fuel system to maintain pressure. Lot of variance here.

Oh, BTW, the stock exhaust can handle up to 700 rwhp as is. An axle back will gain you almost nothing. Long tube headers could gain you roughly 25 hp, but not very cost effective.

As said, intake upgrades are not bang for the buck friendly.

Getting the exhaust out is, as is turning up the boost. Some nice 1-7/8 headers, high flow cats and a full 3" exhaust is where I would go.

Next would be a boost friendly block and fuel.

Well it's not entirely about making more power but if that happens as a result I'm fine with it. I'm more interested in getting the car to run as optimally, reliably and safely as I can. If that means some bolt-ons or fuel upgrades would help to achieve that then I have no problem with it.

Then if this is your goal, stick with what you have. All of the major suppliers of FI units go to great lengths to design and market a system that will deliver optimal power and still survive the test of time.

If you poke around here some, you'll see that all of the suppliers of basic FI systems produce around 550 rwhp with their canned tunes. There is a reason for that. The conclusion I draw is that all suppliers come up against the limitation of the fuel delivery variances and warranty.

Another factor is engine life is compromised inversely with increases in power levels. It is know that somewhere around 650 rwhp the rings can seize on some engines (again, results vary) if full power is applied for a long duration, i.e., road racing.

Not trying to sound too negative, but your Procharger system is about as reliable as you can get as is. Not much you can add to it to increase reliability. Give the guys at Procharger a call and talk to them first if your looking for increased reliability and a little more power.

Hey thanks Atomic Ed, I really appreciate you taking the time and the advice. It makes sense and yeah I can tend to be overkill sometimes with supporting mods which is why I wanted to ask. I think I may do at least an axle back to get the sound I want and would love to do some datalogging and may invest in that HP Tuning software once I get more details on it.

As I'm inquiring myself about datalogging here is what HP sent me.

Joseph, You can order VCM Suite PRO for GM.
It comes with 8 free credits,6 of which you will use to tune your car.


So that comes with purchase of it from HP-Tuners website. My shop that tuned mine said they would supply all of the PIDS which they use to monitor/tune the car because the HP-Tuner comes naked and you have to add your own PIDS. My shop is also going to give me every tune they applied to the car for references. Not to say I'm going to change anything in the tune but it's nice to have. I mainly want to learn by datalogging and researching.

Not sure where they got 6 credits from. The 2017+ Camaro only requires 4 to tune the ECM.

I hear ya! In spite of my precautionary post, I'm planning on getting HPtuners for myself. :0

Not sure if they are throwing in some for the TCM. M6 here so don't need them.

Joe

When you get a list of the PIDs do share. It would save a lot of time. If you can also share the tunes that would be nice, but may be asking too much. Same thought process as you in that I want to learn more.
