Hi

I've heard quite a few issues with the belt snapping on the Vortech supercharger conversion. Is this quite a common fault? Something like this has made me think twice about using Vortech. Or do they supply a much better belt that has zero slippage and is 100% robust with their latest kits... or is this still an ongoing issue?

Any other alternatives to using Vortech chargers, and can you buy aftermarket belts to complement the Vortech charger unit? Generally I believe it is the Vortech 1 unit that is used. Is there another possibly smaller unit that spools up quicker therefore providing more torque lower down the rev range (but with less power top end)? Mercedes charger units start producing huge amounts of torque very low down the rev range (between 2000-3000) but they use a slightly different charger set up apparently which is more than just a bolt on.

Belt problems aside, how does the stage 2 charged R32 (with approx 350bhp) compare to other similar powered cars up the quarter mile straight? For example an E46 M3 (which has an approx 13.4 quarter mile time stock)? Do you get lots of "torque" steer (as the R32 is generally a 2 wheel drive car until pushed to the limit), or do you find the Haldex kicks in before this happens?

What is involved in the process of going to "stage 3"... I assume the fuelling is increased more, and is a thicker head gasket required at this point.. and finally what kind of power and torque (lbs/ft) is developed?

Thanks for any help and info.

Thanks guys for your replies. What turbo conversions are available out there for a rhd R32? I know HPA do a top quality one but very expensive. What other alternatives are out there? I have heard of EIP. Are there any other makes not so well known? Cost for EIP and full conversion seems to be around the £5k mark from what I have heard (I might be wrong on this). The Phirm (thephirm.co.uk) used EIP for their turboed mk3 VR6 and they rate it a lot. I believe it's closer to £9k for the HPA but not sure on this as I read about it PVW mag some time ago.. it might have been for the 400bhp conversion. What is the approx cost of the stage 2 vortech conversion for everything including remapping? Is there a huge difference in it between stage1 turbo and stage 2 charging? I know a lot lot more work is involved in the turbo conversion but the reward is that it produces almost 100 lbs/ft more torque.

How much cheaper is it to do a turbo conversion on a left hand drive car? Is a lot of the cost the labour in actually getting it to fit a rhd car? Are there any German companies that specialise in turboing lhd R32's, other than HGP?

Issues with the belt are rare. I think my big issue was the fact that the belt I was running had slipped badly. When I was running it in, the belt was fairly loose, so it slipped. Then as I put the miles on, I tightened the belt. But in between this I was giving it a bit of beans till the belt slipped. Then get home, tighten it, and so on. Because the belt has slipped so much, I think it was knackered! Then when it had all run in, all really tight I went to thrash the pants off it, the belt kept popping off.
When I installed a new belt and tightened it up straight off, the car felt so much better! So if the belt ever slips, replace it! I only found this out after speaking to other VF users in the US.
