After tons of research on the forums (thank you so much guys), I have decided to save up for the bigger Maggie. My main reason is for how well this blower dissipates heat and the high ceiling out of the box. The car is bone stock and will stay that way till the blower kit is purchased. My only planned supporting modifications are either LT4 fuel conversion or the weapon x port injection if a way to port inject the 2650 maggie is available at the time. I'd like to do as much as possible to avoid opening up the engine, so I'd be stuck with the stock cam and stock fuel lobes (will probably go with a mild 38% blower cam if I go with LT4 fueling). I plan to keep the stock non npp exhaust including factory headers and run an offroad test pipe (no cats).

I have read about so many of you guys get hurt by not buying big and buying once. I have no plans to forge the engine or open up the engine any time soon. This is the weekend toy, and will be super low mileage.

Originally wanted a 1LE (as the user name suggests) , but wanted something new and swinging an extra 10K at the time would have forced me to keep the car stock, plus I realized I would rarely ever see a road course or autocross

The plan is to keep it in the 700 whp range and pray that my 2020 engine is not ill-fated with the super tight piston ring clearance. I have 93 Oct and e85 all around me, so I may consider flex fuel if I go port injection, otherwise its 93 Oct all the way on the lt4 fuel system.

I'm really trying to steer clear of the full bolt ons as I am almost sure to get drug into an almost unstreetable naturally aspirated build. Drivability is very important. I know any small blower like the 2300 Maggie or even a damn p1sc or lt4 blower will get me to my immediate goals, but I know the day will come when I want to go bigger with at least drop in pistons and rods and will regret my original purchase.

So the goal of this post? Share your thoughts, opinions, maybe include how long a small entry level blower setup lasted for you before you went bigger. What would you do in hindsight? Did you regret going full bolt ons before purchasing a blower, etc.

Good choice for sure. Best cooling of all the PD blowers so you should see IAT's in the 110 to 120 range. So if this isn't an SS, what is it. If you do the Lt4 HPFP and Injectors you can easily make 700. You might consider the JRE boost a pump to make sure your low side doesn't fall to far. You won't be able to run very much E with that fuel system and the 2650.

Never mind on the what is it. Just looked it up and basically its like the 1960 and 1970 when Gm had light weight entries that had no frills. Like the Impala, Bel Air and the Biscayne but you could get the same engine. Cool, about time GM did that again.

Thanks for the reply laynlo, your posts were amongst the most informative for my future goals. Yea, I got a chance to drive a 1SS but the difference was nearly 10k compared to my bare bones LT1 model. I'd sacrifice the creature comforts in the 1SS, 2SS or 1LE to afford some forced induction in my situation. I just needed to get in a new unmolested manual v8, everything used I test drove seemed abused and knotchy as if driven hard by inexperienced manual drivers.

Looks just like my 1ss seats. The 2SS seats are heavier then what you have. Not sure where they save almost 300 lbs but that's not all bad.

I just installed the Maggie 2650 on my car, and it went great. I just finished it up, so I haven't gotten it out on the road, but will in the next couple days. Because I only have experience with installation so far, I will only comment from that aspect.

I'll start by stating I deviated from the installation manual in a couple ways. First - I didn't want to route one of the intercooler (it's the return hose, I believe...) hoses below the snout. I thought it would look more balanced if I routed it above the snout, next to the other hose. Next - I added a heat deflector under the blower, which really didn't effect anything else.

Regarding the hose relocation - it took a lot of test-fitting the air cleaner and tube assembly. Most of that was due to me just making sure that stuff wasn't rubbing together, that shouldn't. That included hose clamps rubbing on electric bundles or other hoses. I took time to clock them so they wouldn't rub on stuff they shouldn't. The angles of the hose-turns and bends took a lot of time for me to get right. Had I followed Magnuson's routing, it probably would've been better, but I wanted to keep the hose isolated from engine heat as much as possible. My suggestion is to just take time, and make time for test fitting.

One part of the instructions that was a little off for me was routing the primary wire harness that is routed on top of the OEM blower snout. Maggie's instructions direct you to route it under the front of the blower and snout, which is fine, but I missed where I was supposed to run it between the OEM-oil separator and the front of the blower case. I ran the loom in front of the separator, and by the time I had to connect the No. 7 ignition coil, there wasn't enough slack. SO - make sure, if you do have that separator (which I don't think anything but LT4-cars do), that you run that loom between the separator and blower case. After you do that, all is good.

It was a pretty fun install. I look forward to driving. I have no regrets. Good luck.

Nice plan, pretty much exactly what we have done with my son's car, his is an otherwise stock 2018 1SS (like Greg's) with a 2650 and made 600 RWHP on 91 pump. It was pushed to the absolute limit of the stock LT1 fuel system so we spent the quarantine time developing a port injection system for the Magnum 2650 on this otherwise stock vehicle and have been vehicle testing for about 2 weeks now.

With the port system and our dual in-tank pump system, we are now running full E85 at 11psi boost and over 20 degrees of timing. Currently waiting on more pulleys from Magnuson and then we'll bump the boost a bit more and then head to the dyno. We expect to be right at 750 RWHP on the E and just under 600 RWHP on pump.

Not really much to see as it's mostly hidden by the blower, but here are a couple images

Yes toohighpsi, I had read up on the swap from the non intercooled 2300. Your kid must be ecstatic! Heck, I know I would be. It is very encouraging to see it possible to port inject the Maggie 2650. That's about where I'd like to sit power wise on this factory rotating assembly. Hopefully I see a small bump running 93 pump @ sea level.

Pretty cool, and you made this stock pistons, stock cam?

I think so if I read that post correctly. Pretty amazing how this 2650 maggie blower performs even on low boost compared to the lt4 blower. Those low IATs :drools:

Can't help on much besides I saw the mention of port injection. I am positive Crawford Racing will port inject the blower. I am following Erik Pena's build and he sent his 2650 for port injection

Do you have more pictures you can share when you have time?

Will do soon, my son did a beautiful job on this - if you have a 2650 Magnum already, it's a simple bolt-on setup for that blower.

He's finishing modeling for one on my C7 Z06 LT4 right now, can't wait to ditch the meth and just fill with E at the pump. I'm sure I'll be at 900+ with the vette in no time!
