I see in searching a couple guys on here were working on running a procharger set-ups on Ls motors but didn't see any updates. Anybody complete theirs? What brackets work? I was looking at Procharger's transplant kit but I don't think it will fit without hacking into the inner wheel house. Right now my LS1 is bone stock so I'm thinking about a P1SC head unit.

cam-

I spent a lot of time looking into this as well and you'd have to piece together your own kit. A C5 bracket would likely be a good start but all in all? After researching and riding in a few centri cars... I think these centri chargers are best suited for the drag strip and/or a cruiser that looks/sounds baddass. For sheer performance and fun factor I think the TVS maggie is the way to go. Instant torque everywhere and you can still boost an LS1 to 550-650 rw

there is one person on here, who procharged there firebird. I forgot the members name but i did save the picture. I believe he used a gto procharger bracket. I will be doing the same thing to my car after i get enough money saved for the brackets and piping since, i still have d1sc headunit from my last setup. but anyways here is a pic.

That's a good point, I had not even considered a TVS yet. Might have to do some more research

Hence another reason i am going single turbo, i can mount it wherever my mine creates a bracket and plumb it the best way that benefits me as well.

That's always an option, just not for me. I have way too much money wrapped up into my exhaust and I would like to be able to use it...lol.

cam-

Turbos also I leave more for track first, driver second type deals. I've been part of a TT 6.0L build for the past two years.... This thing is SICK theres enough potential for 1000 rwhp out of this thing. With the stock 6.0L cam it put down 644/678 whp/tq and this is just the beginning... But it is pretty radical and doing turbos for mild builds is kind of a waste of potential IMO especially if you want to do a factory clean install its a LOT of work and effort. But make no mistake if MAX power is your goal then TT is the way to fly.

That said Im with 406tpi I have WAY too much invested in a complete 316L madrel bent purge TIG welded exhaust to tear it all out lol. For now Im onto bigger cubes and new tech so Im staying NA for the time but Im pretty sure its going to be a Maggie next.

Plus Ive spoken with guys who are fortunate enough to own all three types of boost. For instance Brains from Ls1tech has a Paxton centri charged Viper at 9psi putting down 675 whp and a TVS 2300 maggie ZO6 at 5psi putting down 566whp so most would laugh it off and automatically declare the Viper a winner on paper BUT the maggies has power EVREYWHERE throughout the RPM band not just at peak so it takes out the Viper and he claims its a hell of a lot more fun to drive.

In my own experience I can also attest to the fact that centri chargers make great power but they are similar to turbos in that when they come alive they fly but they are kind of peaky and a bit radical and not at all ideal fro my style of driving. I like to romp around corners and on/off ramps and whatnot and with a centri it would be hard to control or force you to go slow. With NA or a maggie its just full on power everywhere and tons more fun. Plus.... 550-650 rwhp is nothing to sneeze at

Cam, it appears you and I think alot alike. The more reading I do on the eaton positive displacement sc's the more I like it. My car is never going to be a max effort track car. I have too much invested in the car and I need to be able to drive it around town to get my money's worth if you know what I mean. I dropped in a bone stock brand new LS1 about 4-5 years ago and have been very happy with it.....it's drop dead reliable and gets great milage even with 4:11's. I thought about putting a set of heads and a cam in it for more power, but I don't really want to give up all the qualities of a stock motor. That's what lead me to thinking about boosting the stock motor instead and still be able to put down 420-450rwhp.

So now I guess I'm on the hunt for a MP112 or something similar.

Absolutely, that is a reason i have the 89 RS that should be a NA 10 second car in a few months and then the 86 will be a single digit car if all goes well with the smaller 5.3. Neither are show cars, they really get driven and abused allot. So, a good looking setup is nowhere near my goals, and just the thought of destroying cars with a junkyard 5.3 is going to be a blast.

A blower is a idea and i might think about it later on the 89 just for the hell of it, but the head unit ect was just too much initial cost.

I am looking forward to seeing how the turbo will drive, it wont be easy getting it right, but with a carb and boost, i like the challenge, there are several doing it now, so it is not a huge deal, but a single turbo is less plumbing and cheaper for me, i cannot justify twins, they twin setup will spool a lot quicker, but i am also not wanting the tires to blow off on the street as easy as twins would, but it will happen anyway. Seeing a 4.8 make 700 RWHP on 16 pound made me say that i was going with a 5.3, cheap, and expendable. Cannot wait to see how long the 10 bolt will not last.

Just my two cents, but for the money I'd go with a maggie (which I did). You'll make all the power you'd ever want plus its about as easy as swapping the intake. I looked into a procharger and even briefly thought about a turbo but since I'm building a nice street/show car I went with the maggie. One of my good friends has owned all three types. He's had a procharged 355, a turbo 355 and a Lightning with a ported blower that made about 500 rwhp. He said that the Lightning was the best fun he has had on the street. I'd go with something a little bigger than a 112 though. Try a 122 or a TVS 1900.

You have a maggie on a 3rd gen? Which kit did you use?

bad86z28

iTrader: (1)

Yeah, but its not yet running. I used the kit for a 2004 GTO. You can see it here: https://www.thirdgen.org/forums/ltx-...8-project.html. There's not a whole lot of technical information yet, but I'll be updating it as I go along.

406TPI

iTrader: (1)

Nice project you got going on there...thanks for the info. I came across a GTO kit new with the older mp112 blower on sale for $5K brand new...still kinda hoping I can find a used unit somewhere though.

bad86z28

iTrader: (1)

I got the TVS 1900 used for a little less than $5K. Keep looking, there are some deals out there. I found mine on ls1gto.com. A lot of those guys have run maggies so you can usually find some used ones on there.

cam-

I agree I'd go for a 1900 at minimum ( 2300 even better ) as you dont suffer any ills from going bigger on maggies as you would with say a P1SC vs an F1A or the like in terms of centri size they are actually mostly the same housing its just the trims and orifices that change with them which makles them more/less street friendly. With maggies they just make the screws and housings physically bigger so theres only gain without much sacrifice.

Besides I'd much rather run a 2300 at 5psi than a 1900 at 9psi to make the same number. CFM is the key to power and the less PSI you can put into the engine the better imo. But like anything im with you all $$$ makes most of the decisions around here

406TPI

iTrader: (1)

Thanks for the tip...I checked out that site....they seem to be big on maggies over there. I think it's funny how different sites have trends. It seems like on ls1tech most guys opt for prochargers over maggies. The more I read about maggies, the more I want one.

I do like the 1900 and 2300 over the mp112 but there also seems to be a big price differential....I don't know...we'll see what shakes out in the next couple months. I'd perfer to buy a new kit but if I find a decent deal on a used one I might jump on it.

cam-

Very true. Research and an open mind gets us all down the track faster, safer, and cheaper. Theres always the holdouts for old tech and truthfully thats how you need to compare LS1tech to LS1gto and the like. LS1tech is old now so it has a lot of old school builders still running centri systems in pursuit of all out power. Granted if you just want to get down the track fast then they are a better way to go than a maggie but thats about the only advantage imo. Plus the maggie tech has only really gotten into the "real" performance game in the past few years. The 2300 kits only debuted a few years back so that was also a factor in techs neglect to use them. Plus I have to hand it to Bob from EPP ( gone now they folded in recession *sigh* ) but anyways Bob had STELLAR customer service and really pushed the centri kits and his hard work sure paid off in sales. So did A&A Corvettes over at CF they also sold a TON of Centri kits. Its mostly these kits floating around now used at uber cheap prices that guys are grabbing up and running. Anyways...

Whipple also make a decent piece but they recently pulled the plug on their new big boy that would have been AWESOME. Cest la vies.

As for the 1900? That'll get you in the 5-550 whp range pretty easily so its not really a bad choice and you could crest 6-650 with all the right pieces ( cam, pulley ratios etc etc )

bad86z28

iTrader: (1)

I'm shooting for the 6-650 range personally. I'll let you know how it goes.

406TPI

iTrader: (1)

Good luck....my motor would never support enough boost to make that kind of power. I just want 450 at the tire...that should be enough to get me into the 11's on a street tire.

Guess this thread should be renamed to "Thinking about Magnacharging the IROC"...lol

cam-

'

That'll be cake. Very reachable goal with the MP112

Im hoping for 450plus NA this time around lol

Then in a year or two 650plus with TVS 1900 or 2300 boooooooost

cam-

Bob over at former EPP made 672 rwhp and 752 ft lbs of torque through an LS3 in a Hummer with a TVS 2300 at 14psi and thats on 35" tall tires too so its very doable

Performancetrucks.net from LS1tech has a significant roots blower population. It seems the people looking for a fun street engine go roots. Max power guys go turbo and they get excellent results for each. Even completely stock engines with just a SC on top put down exceptional numbers

Anybody know for sure if the LS1 GTO belt routing shares the same centerline (belt depth) as the f-body routing?

Never mind..I found the info I was looking for. They are the same.

Oh, you wait will my post tomorrow night

406TPI

They are expensive, but no more expensive than a Procharger kit. I was able to get a pretty good deal on my new kit from a dealer. The Mp112 with the 90mm NW TB was WAY under what you typically see them advertised for. The Procharger kit I priced out was actually a couple hundred more than what I got the 112 for.

Blownz28man

iTrader: (2)

I was looking at the Bigger Blowers. For the tuner kit it was like 6K+. What do you guys think of the Corvette style procharger? Think the core support would be in the way the the Procharger Inlet?

cam-

Nice! Are you going to dyno it? If so Id be uber curious to see what it puts down.

Your going to love that thing man... Seriously.

How about the LS6 cam swap while your at it? You should upgrade your valve springs to handle the boost anyways and the LS6 cam is great for boost and can be had for a couple hundo. Still stock type driveability but it'll wake it RIGHT up.

Of if budget allows go for a custom grind boost cam. Man Im so wanting this now LOL and I havent even got my new engine in the car yet haha

SICK....ness

406TPI

iTrader: (1)

Yes, it will be on the dyno as soon as the install is complete. I'm hoping to have it ready by mid April....just depends on how busy the wife keeps me around the house...I kinda owe her since she let me spend all this money..lol.

I'm gonna stick with the stock cam for now. My motor only has 10K miles on it so I'm not worried about the valve springs. Maybe in a couple years I'll look into a blower cam for it. I opted for the bigger TB becuase it's supposed to help lower IAT's as well as pick-up 20-25hp at the tire.

If it puts down 450rwhp I'll be tickled. I have the advantage of the 6 speed but the disadvantage of the Ford 9" sucking up some power. Sure wish I would have opted for a different ratio when I built this rear last winter...4:11's and the low end torque of the blower will make 1st gear about useless I'm afraid.

cam-

450 should be easy and safe. Im sure you are aware of this but boost does put a lot more load on your valve springs so new or not isnt really the issue its whether or not the springs have enough seat pressure to control the valves. I havent really looked into what the stock springs are good for so thought it worth mentioning.

Otherwise? Looking forward to results

406TPI

iTrader: (1)

That's a good point...it seems as though the breaking point where they recommend upgrading the springs is 8psi and above. So I should be right at that point according to the dealer that I bought the unit from. However, I won't know for sure until it's up on the dyno.

bad86z28

iTrader: (1)

I'm sure you'll be extremely happy with your decision. 450 at the wheels shouldn't be a problem even with the 9". You probably will be wanting to change the 4.11 gears after driving it for a while. Just for comparison sake, my old NA setup made 420 at the wheels and about 390 ft/lbs. With the 4.10's first and second gear were about useless and I'd have to pedal the crap out of the car. I ended up going with a 3.73 gear in the S60 for my new setup.

I'll be very interested to see what you end up with after its all said and done. Keep us updated.

I got the raw finish. The polished version was around $1K more The mat black I think is only availible with the TVS series.

Well the mat black looks cooler i think than the polished, what a waste a money to have someone polish your supercharger. you can always polish it out later.... so is your just the raw metal surface you are saying?
