Looking awesome You are going to really enjoy the power and torque of it. Just one thing to note about those olson pulley set ups, if you watch sloppy mechanics’ G48 video he ended up having an issue with the pulley coming unpressed off the center shaft and ended up having it tig welded to prevent it in the future. Not sure if it’s been corrected since then but worth dealing with now rather than later. You’ll have to find and watch the video for exact specifics but I thought I’d mention it.

I did see that pulley on there. Looks like there’s going to be a bit of a bidding war! Should be interesting to see what it fetches.

 

Yup. I watched that all unfold with sloppy when it was going down. I think everyone learned something from it. Olson is in fact doing a couple of quarter inch long tig tacks on the hub to shaft now.

Haha I threw that pully on fleabays for 99 cents and then nothing happened for a day. I was getting a little bit nervous lol.

 

Thats good that he’s tacking that on now you shouldn’t have any issues. What size is that Olson pulley? You just never know with eBay but something’s just go like crazy. It went up too quick I would’ve tried to snag it up since I’ve got a stock pulley. Be nice to add a little bit to it.

 

2.45" I believe. I'll be running a stock diameter balancer. Like a dumbass when I put my powerbond SFI balancer on I didn't pin it even though I told myself too. In a way though that might be a blessing because I think I am going to buy one of the Summit Racing 8 rib SFI balancers so that I can ultimately run an 8 rib belt setup without spending the asinine amounts of money for the innovators west stuff.

 

Definitely going to want to pin that thing on there. I know it can be done in the car its just a pita. Actually even out of the car its a PITA, that hardened crank material takes a while. I would get everything running first and maybe then think about an 8 rib setup. I know Matt's G48 was on the 6rib just until recently and he made 16psi with very little slippage once he got his tensioner all squared away. Thats a true testament to the 6rib if you've seen the way he abuses that thing. I have the stock truck tensioner and it holds the stock 8psi just fine although my cheap *** $13 belt looks like it wont last forever so my advice there is to make sure you do this on a nice belt too. If you still cant live with the 6rib then go for the 8, but that road is another accumulating cost for something fun and on a budget.

 

I was only thinking of making the balancer swap now so that I don't have to go in there again in the future. Even if I did make the swap now I would still run it 6 rib for a while. 8 rib power steering and alt pulleys are expensive enough as it is. Not super critical at this time as you said. That being said It would be easy enough to just lift the rack up and knock the bolt out of it, pin it, and slap it back together with the current unit.

Do any of you fine gentlemen have a recommendation on what MAP sensor to run and what would be a good fuel injector to run. I will be on pump gas only. We don't really have E85 around here in the PNW. I don't really want to make more than 600 wheel anyway. I don't need a new short block anytime soon.

 

The snake eater performance injectors seem to be the go to without breaking the budget from what I’ve seen lately. I’d probably just get a set of 1000cc or 1500cc for the money. I know that sounds huge but when you do want more (and we both know you will haha) or do/can experiment with some e85 you’ll have plenty of room for growth. I think your cammed ls2 won’t even sweat to make 600 on pump gas. What does it make right now?

 

Ls1 with CNC ported PRC heads. 420 wheel. Even the smallest SEP injectors would do way more than anything I would ever consider.

 

For some reason I thought you said it was an 05 vette I guess you said c5 though, my mistake. I only mention the larger injectors because the price difference to get smaller just isn’t there with the SEPs imo. Why limit yourself right out of the gate? Now if your buying id1050s for $1,000+ that’s a different story, obviously then I’d settle for smaller because that’s too rich for my blood. I think I read stock lsa injectors are done close to 600... maybe 570ish. Those usually are around $250 on eBay. You’ve got options you just have to figure out a budget on them I guess.

 

Sorry I missed this part. Your new lid should’ve come with a brand new 3 bar map in it. Mine seems to work just fine I say just use that one. The connector is the ls3 style so if you don’t want to hack your harness up they make an adapter for it, I think it’s around $20 that’s the route I went so I can convert back easily if I want.

 

I am a novice tuner. Cut my teeth on the cam heads and larger throttle body setup I currently have. I am using a Gen 3 411 PCM. I think in the minor poking around I have done that it is not easy to run a 3 bar MAP on the gen 3 PCM? 2 bar is more preferred. I'm all ears for any advice.

On a positive note my fancy billet fuel rails showed up today.

 

What rails did you use? I bought Radium and the final cost was a bit more than expected due to all the plugs needed in the rails. It does work great though.

I was told quite a while ago by somebody that you can use the 2 bar MAP sensor. The lid had a 3 on it, so that is what I used. If you are going to send your computer out for tuning, they should be able to tell you easily if it will work.

 

I think a map sensor is a map sensor regardless of 1, 2, or 3 bar as long as you have the correct limits and offsets I can’t see one being better or not. You also already have that 3 bar, why not use it? I’m using the one that came on my ctsv lid and I have no issues. Have you decided if you’re going to run the car in speed density on a custom 2 or 3 bar OS? Now if you stay with the MAF that will need an upgrade more than likely because I’m sure you’ll max that thing out. Im also on a 411 pcm on a 3bar os, no o2s, open loop SD. Still working out some lean tip in issues but runs well otherwise.

 

I have the Aeroflow performance aluminum rails that are sold on Ebay. I have not taken them out of the box yet.

I need to figure out what I am going to do for a regulator. I was leaning towards the Aeromotive 13129 but now I am contemplating using one of the Chinese copies just for the sake of keeping this budget friendly low buck boost. That being said, I will not sacrifice reliability for being cheap.

I am planning on tuning this thing myself but just getting a boost ready base tune on my 411 pcm is going to be a challenge for me. The drive tuning is pretty easy for me.

 

So far everyone I've chatted with that has been around LSA supercharger swaps including Olson have all said to just speed density tune it and go out and have fun.

 

Partially assembled my fuel rails today. Gonna be a little tricky making a decent looking crossover hose. Ordered 325 bucks in PTFE hose, fittings, plugs, and an Aeromotive regulator, gauge and injector connector adapters. Still well withing budget. Especially if I go with the SEP injectors.

 

I really like those rails the more I see them on there. Maybe I’ll upgrade! The sep injectors are definitely the budget way to go. This is going to be a blast! Almost there.

 

More fuel rail goodness for swapstang.

 

Haha it’s like billet fuel rail ****. The gratuitous rail shots. Looks awesome I think you’ve convinced me to upgrade. When I install my flex fuel sensor I’ll probably do it. Did you look into the MAP sensor conversion harness I mentioned? Unless you’re ok with cutting the plug off your old one. I only did this so I could convert back. Also, is your intercooler brick reinforced?

 

I bought a 24" ls1 to ls3 MAP extension harness should work great no cutting. I will be able to adapt IAT without cutting the factory engine harness as well. Brick is still stock and brand new. I may send it to olson as well and have him to the reinforcement and AN fittings but I haven't decided on that yet. Still trying to keep the budget way down lol.
