Hey guys - lots of people have been asking me for more detail on the internals of Heartbeat, especially when it comes to what makes it different from other kits on the market.

Our R&D team created this cutaway drawing that shows the insides of Heartbeat, and explains the unique features. Check out the inlet and input shaft design in particular, and how our engineering team managed to maximize the airflow going into the rotors (superchargers hate restrictions on the inlet side). You can also see the intercoolers - we went with the most advanced intercoolers we could find, and the same technology from the same company is used in F1 heat exchangers. The cool thing about them is not just their efficiency, but how well they flow and minimize pressure drop going into the ports.

Enjoy. A little light reading for a Friday afternoon for those of you, like me, that get excited about the technical detail:

Matt, thanks for posting the above diagram. Looks really cool! Quick question, what's the dimensions of the chargecooler bricks used? They look a lot bigger than say the Eforce ones but I can't seem to get exact dimenssions.

Also you mention f1 heat exchange technology. Can you shed any light on what is different between that and say a conventional change cooler core?

Finally, from the testing your teams (and external 3rd parties) have carried out, will this unit support as much power as the LS9 supercharger assembly?

0Matt@Magnuson

Great questions. The CAC bricks are 1,385 ccs . The difference in them vs a traditional intercooler are that they are designed to maximize cooling and minimize boost pressure drop:

- they are extruded tube (not rolled) with thickened leading edges profiled to reduce restriction
- thin walled on the sides, dimpled for coolant turbulence, webbed for strength
- the fins are louvered for maximum cooling with minimal pressure drop, surface-fused (not edge-fused) for maximum transfer, & full-length (minimal end bypass)
- dual-pass with double-sealed caps

I'll upload a more detailed explanation of the above shortly - we just finished a video interview with our chief designer.

We're convinced that Heartbeat will outperform an LS9, even a ported one. Proof is in the works - stay tuned!

Any ideas on what this blower will do on a ls 3-6 speed vette?

0Matt@Magnuson

We're seeing 510-530 rwhp on an otherwise stock C6, with our EO certified/50 state legal kit (around 6-7 psi). The manual kits tend to be on the high side.

What would you expect from a stock LS3 Grand Sport 6 manual with headers and a tune with the stock pulley?

LedfootLarry

How about an upgrade intercooler for the older Maggie tvs2300`s , couldn`t be that hard to have some manufactured to the new specs, I will buy one !

chuntington101

I hope the next thing the Magnuson crew will be working on is kits for the 3300 rotor set from eaton!

LedfootLarry

Yaaaaaaaaaa, what is talkin so long, waiting for whipple to take over?

0Matt@Magnuson

Are the headers already on the car, and if so, do you know what your car is putting to the wheels with the headers? The headers should add roughly the same supercharged as it does naturally aspirated, provided you have a good tune.

chuntington101

I think it's taking eaton a while to get the rotor packs out. I'm sure magnuson want to get hold of it as the market is pretty massive and hopefully the casting / tooling cost won't be that much. Obviously there is still a little r&d work required but hopefully kits will be out soon.

LedfootLarry

I think magnuson will only manufacture the new style blower instead of the jackshaft model, which is a shame because of the overdriven feature of the jackshaft model, jeez this sounds gay

NorthTXC6

I've got the heartbeat installed with pfadt headers, stock pulley, and a tune, and am putting out about 520hp to the rear wheels but have an automatic, not a manual...have run it now for about 3k miles including a round trip from Texas to Bowling Green, runs smooth as can be...

does the drive belt route around the upper radiator hose?

NorthTXC6

Yes, it is actually routed below the upper radiator hose, I'll try to take a picture tomorrow AM and post it

383

Oh man MAJOR selling point! I hate belt changes on the e... other blower .

TLS_Addict

Must be an LS2 thing, I think some 2008 LS3s are strange too.

It takes me maybe 10 minutes to change the belt on my 2013 (I have the E-Force).

383

don't you have to take off the upper rad. hose to change the belt?

I got 515 rwhp 2008 ls3 no headers bone stock except for ati super damper temps 205 to 210 around town . 470 trq rear wheels.6sp manual

old motorhead

What size snout pulley and how much boost are you seeing? Sounds like a fun ride
