Any luck?

it's a royal pita for sure. The belt drive is slightly off and then you have to get a custom pulley made or it will jump around with the stock pulley and eat up those $60 belts like no tomorrow. I was not able to get rid of belt slip completely and made 852whp / 785 tq at around 18.5 psi.

Honestly, I'd get a blower made for the car / engine unless you do your own work and have ALOT of patience and get it on a deal.

"The intake bolt pattern and port configuration is the same for the LS3, LSX-LS3, L92, LSA and LS9 cylinder heads"

The offset for the supercharger pulley is different, so using an LS2/3 accessory drive requires this modification:

Unfortunately I'd recommend anyone to steer clear of that website!! I've had a terrible experience with Olson Kustom Works aka "gimmetheboost.com", BOTH times I tried to deal with him!

First time we bought stuff from him he took almost 5 months although.he originally told me a few weeks. Stopped responding to emails, calls and messages then suddenly it shows up 5 months later in a box with no packaging and just the fresh metal pieces thrown in there with nuts and bolts...

As if I did not learn, I ordered the above mentioned stuff and this time he sat with my money for over 6 months!! I got fed up of his excuses of how his machine kept breaking for the first 5 months and then again no response, so I filed a claim and the SAME NIGHT I got a nasty text from him saying how I was an IMPATIENT POS and DON'T KNOW ANYTHING ABOUT HARD WORK (lol are u f**Ken serious???!)

He then tried to tell paypal he shipped it already and provided a dead tracking number lol. PayPal waited for a few weeks and gave me my refund. Entire ordeal took almost 7 months!!

STAY AWAY FROM OLSON KUSTOM WORKS AKA GIMMETHEBOOST.COM!!

needs one of these and a lot of extra cash

That looks like it mounts on the water pump? Hmmm... interesting cos my tuner fabricated a pulley drive on to my ls3 style water pump, to get more belt wrap and was able to get the ls9 blower up to 17.x psi which I made 852whp / 785 tq

I've been thinking about eventually going to a ls9 2650 Kong. Currently running an Eforce with A&A secondary drive and 8 rib crank pulley. It looks to me like you could run a ls9 blower on a ls3 with an 8 rib set up and use the forward 8 ribs on the blower pulley. It'll be a much shorter belt with the A&A setup so should be able to spin it pretty hard.

I have seen people with GS dry sump LS3's be able to do it. The have a shorter crank snout so all the LS9 accessories work and you can run the 10-12 rib setups if you want to crank down on them.

The people that have done it on a LS3 can on seem to run a 6 rib so they cant make a ton of power with out belt slip. They use the stock LS3 accessories from what I have seen and run a 8 rib blower pulley with a 6 rib belt.

The company that makes the LSA kit for the C5/C6 said they does not offer the 2650 because they can not get it to fit or line up. The 2650's they make have a longer snout on the blower I spoke to Kong about making a custom front snout for the LS9 2300 and 2650 but he said it would not be cost effective.

Wagner's kit does not offer a 10 or 12 rib kit for the LS3. Limited to 8 rib.

To make reliable big power like the ZR1 boys do you will want a 10-12 rib setup. Hell most of the big power guys are now running that new tensioner setup Kong put out with 2 idlers.

It’s my understanding that the ls3 with an 8 rib crank pulley will line up with the front 8 ribs on the ls9/kong ls9 2650 blower.

Kong stated it would not line up. Greg said someone could get the Wagner system but would be limited to a 8 rib. He said the 2300/2650 need more then an 8 rib. The LS3 tensioner setup would not be enough even if it did. Its silly no one has made a 2650 setup for a LS3.

and that's why i prefer my jackshaft TVS2300. i can hold 13psi on a heads/cam LS1 for high-600s to the ground using a 6rib setup: 8.25" crank, 3.8 snout, and cogged 20% OD rears.

PSSSSSHC6

Most people want to go after the LS9 2300/2650 setup because they see how fast the ZR1's are with them. Like any fast blower setups the blowers have to be spun hard. The 2650 and the YSI wont be happy at 15psi. The belt will not hold over 20psi with an 8 rib.

I'd love to have a 2650 jackshaft. I'm making 800/800 to the tire with a 6 rib set up on an Eforce. I made 14 psi but that was on a Gates RPM belt. For what ever reason Gates discontinued them I'm running a forged 416 now with a larger cam. Makes 12 then slips so I'm doing the A&A secondary drive and going to a much shorter 8 rib belt. Going to try a smaller blower pulley too if iat's are good after changing cooling bricks. I think I can get 900-950 on the 8 rib at least and that's all I want.

I here's the offsets for all the ls combos. I drew lines where an 8 rib Corvette balancer would line up. A custom pulley should make it work if it wouldn't just running a standard ls9 pulley. I'd have the crank and tensioner to keep it lined up. Looks like it could work. Not sure if anyone else has done it yet but depending on how things go after my winter mods, I may try it.

The hope is that you don't a lot of money to fight issues without the ability to upgrade. Kong stated a 8 rib would be useless on the 2650. 900-950whp on a 2650 is lazy and not spinning the blower very hard. It would be faster with a 2300 making 950whp. But that comes back to being able to throw some pulley on it with fighting belt slip. Most max effort ZR1's are running 11 rib 2.25-2.35/14% on the 2300's. Most 2650's are running 2.40-2.75/14%. That's to make 950-1050whp through M6.

Just go with a cogged belt, lol

Both Innovators West and ATI through Lingenfelter make wet sump balancers now that provide proper offsets for the LS9 accessories. The hard items to get are the power steering pump/bracket and OEM water pump. Aftermarket water pumps are available. Alternator bracket , AC compressor bracket, AC compressor(6 rib), idlers and tensioners are still available.

Power steering bracket and pump are difficult to come by. An option may be using an electric Volvo/Ford power steering pump. Alot of engine swappers use these pumps to supply hydraulic power for steering racks. A nice bonus would be a much cleaner engine compartment and a lot shorter supercharger drive belt (probably 20" shorter). Just something to think about.

I'm just not sure that an 8 rib belt with the A&A secondary drive system and much shorter belt that only drives the water pump and blower wouldn't be just as strong as the 11 rib much longer belt on a ZR1 set up that also drives the power steering pump.

RPOWU8

8 rib may be strong enough. Not saying it won't work but I know the wet sump LS9 balancer and LS9 accessories do work. Maybe check the ZL1 forums or CTSV forums to see what issues they have had with 8 ribs on LS9 or Kong.

The IW balancer is basically an eight-rib accessory drive section and the 8 rib SC drive section. 4 ribs for the original AC drive belt and 4 ribs for the jackshaft belt for the secondary drive. Then add some space for clearance and then the SC drive section. I just didn't want to deal with any alignment issues. I think someone needs to bolt an LS9 blower on to check alignment to be sure. Would still need some fabrication for idlers and brackets to hold them at that point.

I've been collecting the LS9 parts since 2018. Just found out about the wet sump LS9 balancers about 5 months ago. I'm currently running a V3-TI with the secondary drive but will be switching to Kong LS9 later this year. I've hit a wall with the car and the V3 TI is just at its airflow limits. Need to do some more testing on my A2W setup first then take the plunge with the LS9 stuff. The car has been stuck at low 6.0's 1/8 mile since Nov 2018.
