Harrop or Magnusson supercharger

[Aegmaloo]

Hi all. Looking at supercharging my ls3 maloo.
Just want peoples opinions on the harrop and Magnusson SuperChargers.
Pros and cons of both. Why is one better than the other?

Thanks

Harrop downwards discharges intercooler sits in the base of the blower absorbing 100-110 degree engine heat.

Heartbeat upwards discharge intercooler sits at the highest point of the engine not absorbing anywhere near as much engine heat.

LSA is also the same as the heartbeat...heartbeat is 12k LSA is 10k for an entire engine low comp built for boost, have a read here about a direct comparison from 1900 to 2300 which also includes dyno results: http://www.hsvforum.com.au/showthrea...sus-LS9-Blower

I had the heartbeat on my LS3 for 3 years/60,000km's and never had one issue - changed the belt at 55,000 and it still looked new.. IAT2's were excellent, low to mid 20's in Perth's amazing weather

If i was to do it all over again i would possibly look at a killaboost turbo setup

Hi Nath, did you have a cam in it also or was it stock. I checked out your mods page and it didn't say anything about the cam, thought you may have forgotten so hence the question.

I had factory cam & extractors due to being engineered - still got a healthy 400rwkw and more importantly it was bloody reliable as my daily. Some people chase numbers, i was more interested in how the car drove on the street
