C5 Supercharger
I have a 1999 C5 Convertible. Has any one fitted a supercharger on top, Harrop twin screw type. Im not sure if there is enough clearance at the firewall, an extra lump in the bottom doesnt worry me, if needed. Im in Australia, most blowers ive seen here are Vortech type, side mounts.

I'm not familiar with Harrop's stuff, but here hundreds of people run Magnacharger and Kenne Bell systems. The Kenne Bell generally makes more power because it's larger displacement blower and it's a twin screw design versus a hybrid-roots. All you need is an after market hood and you're good to go.
Do a search for Kenne Bell or Magnacharger and you'll find pages of info about both.
I'm curious though where that belt goes to on the Harrop setup. It looks like it goes down into the valley.

Do you need to replace valve springs to cope with a blower??

I have a friend who would almost pay your trip if you brought over some Monaro parts for his GTO!
I've seen the Harop setup, and I believe they just resell/rebrand it. It's not thier design. The Kenne Bell is not the easiest install, but does produce gobs of torque. Magnachargers are very similar to the Harop setup and also very popular. All you need is another hood. You do not need to replace valve springs for most applications. Primarily, you replace valve springs when you change cam lift, otherwise the stock springs for most applications are fine.
I'd also suggest you also look at the Paxton Novi kits. They are centrifugal, and produce more high-end boost. There is a lot of debate on the pro/cons of screw/centrifugal setups. Personally, I'd rather have a centrifugal type. Traction is already a problem on most tires, so having that low end torque can sometimes kill you. I'd rather have a setup where you can drive and the car is 100% stock drivability until you want to drop the hammer.

FYI, you can also cut the hood if you can't bring one back. There's a thread floating around with several pics of cut hoods that accommodate the Magnuson blower. It's something I would consider as long as I had a secure place to park and something else to drive during inclement weather.

Thanks for the tips, as long as it sounds like a blower, smells and tastes like a blower and goes hard, centrifugal or screw doesnt matter to me. I will do some research on Paxton. Centrifugal seems a lot easier to install. What would you pay in the States for a complete kit ? It sounds like you have been there. Thanks mate.

I just sold my GTO to sponsor the Vette. If he needs some stuff let me know.

I'd recommend emailing Andy at A&A via his website for the typically hp output, but I have his Procharger kit on my 99 A4 and it made 460 rwhp prior to LT headers, now it's 490 rwhp w/ headers. His Vortech kit makes at least these numbers if not better since it's a more refined kit compared to when I bought mine several years ago.
