Harrop or Magnusson supercharger
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?
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
2014 HSV GenF-GTS fitted with a Forced Induction Interchiller
10.373 @135.70mph 29/May/2016
V-Box Results 0-100km/h in 2.89sec
V-Box Results 0-60mph in 2.76sec
Looking for colder IAT's?
we have achieved 11c IAT2 on a 41c day and -8c during winter.
We have proven cabin AC vent temps are better than GM spec, both IAT2's and vent temps are all on video with nothing to hide.
Just read this & the link.

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.
[QUOTE=Nath;..... Some people chase numbers, i was more interested in how the car drove on the street [/QUOTE]
Yep - same here
