Ok so Im a few weeks from spending like $8500 for several boltons to be installed and tuning including the HHP T87a TCM to unlock the trans for my 21 ZL1.

Its been a hard cost pill to swallow to make maybe 60+ more hp. The headers are the big ticket at $2500, and I cant find a local shop that would do any other brands due to their quality and install issues. So Im stuck with those/plugs/wires. Im also getting an IW 9.1 lower and that was almost $1k. Aside from that they are installing everything, burping the IC cooling system and adding water wetter. And also installing the TCM and tuning the ECM/TCM for 93. I already have the rotofab installed.

So total is like $8k.

They are telling me i will be out of fuel system so no E, and Im not getting meth or anything. So I was thinking.

What about skipping all of that and just putting on a maggie instead? Not doing the TCM or the lower or any of those other mods except a tune. So basically maggie and tune.

Can I not do that? Will I run out of fuel with 93? What are the opinions with starting the boltons vs just going to maggie. I'd like to make 700/700 and be done with it.

Opinions?

+1 on this, considering same. Magnuson also gives you warranty if you use their stock ECU tune. Car has to be otherwise stock including exhaust/intake.

[KingLT1]

Ported blower(12 psi)
Headers
103mm tb
Rotofab
JMS V2
Flex and TCM tune

I recently tuned a ZL1 with these mods and it can run E50-55.

Find a different shop imo.

If you just slap a Maggie on it and bolt ons, headers, intake 103mm tb you’ll
Gain about 120whp over stock. The stock 90mm at sea level elevation your going to hit 16lbs of boost and you’ll be on the edge of the fuel system on 93. I think I made 670 with above mods. Your high side going to be tapped out completely around 690.

+1 for the Maggie, this is what I am planing to do as well for reliability and low IAT.

A good thread was posted recently about this:

I did exactly what you are wanting but with an edelbrock 2650.

Netted 670 whp. To me, this is the best 1st step as you have significantly bumped up HP and you have a much better stepping stone to build on

[Blackdevil77]

I'm planning on a ported blower with ECM/TCM tune and that's it, but if I were to do anything else ever, this would be it.

If you didn't need hood mods the Kong eforce is more efficient than the maggi for 7500 and you can swap it in your garage and drive easy to the tuner.

I think there are cheaper (but not completely better in all regards) ways to get to where you want to be, like pretty much everyone's already said. For the cost - I don't think a 2650 is where it's at. There are more than a couple guys here that have posted 2650-numbers at 700 (with 2650s and intake-side bolt-ons only) and some that have posted close to that, with strictly 2650-only around 650. So a 2650 can definitely get you there, and you'll be future-proof'd. Some argue there's no need for a 2650 until 900+ WHP, but you have to spin the 1.7 pretty hard to get to that point. How far do you see yourself going? That's probably the best question.

Unless you're going to build something 900-plus WHP later, going with a Kong/Synergy/etc-port and the rest of the popular bolt-ons will get you that power, and you'll be in the meat of the powerband with that 1.7 straight from the hit, and probably walk a 2650-car like mine. I suspect I'd reel-you-in later, but 2650s need to be wound-up pretty good to match the 1.7 from the hit.

Now... maybe it's unfounded (but I'm pretty sure it's not), but even if I didn't have to deal with smog-issues I have to, I still would've gone 2650. Without adding a lot of weight and complexity for a good enough ice tank, and all the plumbing it could require, it's difficult to control the compressor heat on the 1.7. Porting it seems like a good option, but I'm just a garage/hobby-type - not a professional in with a shop doing these builds all the time. I've heard from a couple shop owners that mention, or suggest, that these max-port-programs pretty much get the blower within an inch of it's life, if it's spun to the point for the extra porting to make a difference (I mean an X-port, over the standard port). The X-ports get out to mid-900s at the tires though, so maybe ?blower life? isn't meaningful to you - or even a thing. Standard ports, though, and the right combination, could get you where you want to be, though, without increasing heat hardly, and probably be as reliable as stock forever.

I'll say that it's not difficult to get into TM with the stock TCM. I, unknowingly (I had suspicion, but couldn't prove it), was running into TM on one of my cars, especially on the 2-3. I probably would've run into it from a dig, but I could never go WOT, having not tested at the track. There are lots of things to help on the ECM-side, but as was pointed out to me, there are still a few critical things in the TCM that can help. Is it worth that money? Maybe not. I could feel it in the car sometimes, but others may not. It masks itself pretty well, so maybe it won't be an issue for you. For me - I just wanted all the low-hanging fruit, so it made sense, and was worth it. It might not be for everyone else, though.

[laynlo15]

I'm a Maggie guy so you know my answer.

[USAFS197]

I'm actually a proponent of the Magnuson 2300 if you can find one out there. Not only is it lighter than the OEM blower but, it's more efficient, too. Not everyone needs/wants the ability to make 1000+whp. Get that with a CAI, throttle body and headers and be real happy.

[SATINSTEEL1LE]

Problem is FUEL. Everyone keeps saying slap this and that on and make 1k and so on. You are out of fuel at like 700hp with 93.

So you need a cam then and injectors as well a some sort of boost a pump for the low side. Or you need meth or something like that. This is what Im talking about.

How are you guys making more than 700rwhp without fuel mods? The maggie is going to push you way past that if you pulley down or add any mods to it.

Nobody is making over 700whp without some sort of fuel mods(Injectors, pumps, cam lobe, port injection, meth) unless they are running race gas which allows for a leaner AFR.

Either way you said that you only want 700whp so what is the big deal? Your goal is easy...mods i listed in previous post will get you close or a 2650 on 93 will get you close. If you want to go above that then it's time for fuel mods.

The fuel mods aren’t cheap but they are super easy. If you port the blower, when it’s removed you are right there with the HPFP and injectors exposed. It literally 30 minutes to remove the pump and injectors.
