Default Overdrive damper for LT1

Hi all, I'm looking for 10% overdrive damper to speed up my Maguson 2300 but not having any luck so far...

Seems ATI nor IW have one. Seems they all support the Z06 setup or direct drive systems.
I have the Magnuson Heartbeat 2300 but it runs on main belt.
The smallest upper pulley is 3.05, which I'm running now but still not getting enough boost with new rebuilt LT1.

Figure I try to overdrive the damper by 10% to get a tad more but can't find one.
It's in a 2016 Stingray Z51, dry sump.

Anyone run into this?

My only other option is to upgrade to the 2650 but it's a lot more work and $$

Thanks,
Pj-C7

I would confirm with someone like Andy at AA Corvette but the Dry sump crank snouts should be identical between the lt1 and lt4. This would lead me to believe you can use an lt4 balancer. I'd go with an Innovators West balancer. It's what I'm running on my Z51 but I have a 2nd drive for my centri so not over driving the accessory belt.

Appreciate the response....I called all the major vendors and it seems they don't make overdriven dampers for the LT1; as it's a single belt system.
Anyway, in the iterum, I managed to get a 2.8" Griptec on the Magnuson which produces 12 PSI. It starts to slip after that but may be ok till the 2650 upgrade.


Thanks,

I think you misunderstood me. I'm saying if you buy an LT4 balancer you should not have any issues installing it on your LT1 since they are both designed for the same crank snout (dry sump). The crank/rotating assembly and blocks are interchangeable between the two engines.

His crank is wet sump. That's why he can't find an overdrive balancer

OP, with regards to the 2650 I believe magnuson does not offer it for the wet sump. Better verify this with them

It is dry sump. I didn't think it had same belt configuration as the Z06, which I'm not familiar with. I thought the Z06 SC was driven by a second/outer belt on the damper. Anyway, I'll look into it. Thanks!

I'm assuming you have the old 2300 with the shared belt drive? If so there is no 10% OD balancer available.
