I will make it clearly known here for ALL
When you are considering to purchase a partial supercharger kit from Raptor you can buy just the stuff you need, we have always offered this service.
In the case of this new Liberty H6 kit I will be right on your case to make sure its done correctly and that results will be pleasing for both you the owner and for us. We are done with know it alls screwing up perfectly good hardware and getting crap results. I have lost count just lately of Holden V6 intercooled SC kit owners which were making around 200rwkw as supplied by us, after a year or so they decide to modify their system, bigger cooler, change this or that ...........and before you know it, the boost is at 7psi instead of 10psi and 185rwkw instead of 200 and they want a smaller pulley to FIX the problem. On the other hand a couple of guys made IC systems so good that they were better than ours and we advised customers to go to them in their area. So, from the start we are gonna set a high bar that sees every Raptor charged Lib getting a good result no matter who assembles it.
So
You will ALWAYS consider the following items regardless of what you think you know:
1. BOV, I will give you all no choice on this, these are critical to good supercharger performance, I have 2 types which we recalibrate for supercharger use. One can be plumbed back and the other is to atmo, take your pick and they will arrive with your SC and other bits.
2. Use at least 2.5" pipe between charger outlet and cooler inlet
3. Use ONLY 3" pipe between cooler and throttle body
4. You must also accept that you may be far less skillful at building an intercooler system than you think you are, or you could be ok. The point is if you install a system that reduces boost to the intake by 2-4psi you will have a hard time getting Raptor to supply a smaller pulley to solve your screw up. We know for absolute fact it is now possible to constuct ATA systems with .5psi max pressure loss. We also know some people seem to be able to build a system which just sucks away huge amounts of boost. Raptor will gladly and readily supply boost upgrade pulleys to people whose system is very low loss, the others can start again. I can provide tips on how to build low loss systems. ATA systems can be heaven or hell, even total hell if they are built badly.
5. If using WTA you can do whatever you like and you cant get it wrong.
6. Another area for problems for the home builders are air filters, there is no end of performance restricting air filters on the market under fancy names.
7. Fuel injectors - I have lately let LS1 kit owners buy their own fuel injectors, they all went the Ebay direction - all had big dramas and ended up buying new injectors - no further issues. I believe one of our Liberty customers found the same thing and upon having his set of injectors tested found that 2 were out of range and not salvagable - saved himself an engine by getting them tested. Either buy brand new or get a set from a low KM WRX and have them cleand and tested at somewhere like Powerflow injection. You need something around 410cc, big injectors are a tuners headache in the low RPM region so try and stay below 450cc unless you are going to 9000rpm
8. Maybe use a set of 1 heat range colder spark plugs
9. If you see a second hand Raptor Supercharger headunit for sale someplace ....... yes you can use it for your Liberty so long as it doesnt have a 90 degree outlet, simply purchase the unit and then send it to Raptor to have the correct pulley fitted and for general check over. You could get very lucky on this one, but your charger will be the older heavy internals type, all genuine Liberty kits get the new light weight charger which has far quicker response.
10. Tuning. An engine in the hands of a bad tuner is a 1 use item so get yourself a good tuner for those not going with xtremeracingtuning who advertises here.
As above I will sell you any individual parts you want, but I want you to get a sweet outcome
