Once your return is received and inspected, we will send you an email to notify you that we have received your returned item. Any item not in its original condition, is damaged or missing parts for reasons not due to our error There are certain situations where only partial refunds are granted (if applicable) Please do not send your purchase back to the manufacturer. To complete your return, we require a receipt or proof of purchase. Gift cards CANNOT be returned or credited. It must also be in the original packaging. To be eligible for a return, your item must be unused and in the same condition that you received it. We will not provide any credit or return for this. We are not responsible for you choosing the incorrect part for your vehicle or application. Special order items are deemed to be non-stock items. Absolutely NO returns will be accepted on special order items. All returns will incur a 40% restocking fee Changing your mind is NOT a valid reason for return or cancellation of an order. All returns must be made within 14 days of the original purchase date. If there is a problem with an item you have purchased, please contact us directly. We do not cover misuse, breakage, or physical damage to our products under warranty. ![]() ![]() Faulty and damaged are also two different things. Absolutely no freight, labour, or any additional costs are included under any circumstances. Please note, all returns and warranties only cover the item itself. If you are not able to provide this, your warranty or fault claim may not be accepted. receipts, letters from a mechanic explaining the fault etc). We reserve the right to ask for proof of this (e.g. This is completely inclusive of all products. a mechanic or auto electrician), otherwise any Warranty offered is voided. For business or commercial purposes, this act does not apply, and warranties will not be given unless agreed upon by us.Īll products purchased by us must be installed by a qualified professional (e.g. We will meet our obligations under the Consumer Guarantees Act 1993 to warranty our items for private use. We don't like to mess you around - if you get a faulty product, then hey it's faulty and we will do our best to replace it. It is a very rare occurrence for our customers, but if it does happen, the more information you can give us about the fault - the easier and faster the process is for us. Hopefully, this all makes sense.We know how frustrating it is getting a faulty product. The ram effect really only matters at WOT.not part load (throttled) conditions. Usually you want to tune it for the peak torque of your engine but this is always open to debate. They make them in different lengths so that you can change the length of the runner to tune for what rpm you want the ram effect to occur. They have 2 main purposes:ġ: smooth the airflow going into the carb/runner which will create smoother airflow (although intake air flow is in the turbulent region.that would be a discussion for another long post) this leads to better atomization and less pumping lossĢ: Tune for the ram effect. Another name for the ram effect is statically supercharged, because greater than 100% volumetric effeciencies are possible, hence you are pumping more air/fuel than the static displacement of the engine. This, if properly setup, can broaden the range where resonance occurs and effectively jam more air/fuel into the cylinder. By putting fuel injectors both at the port and in the plenum you can vary the mass density of fuel in the intake runner (but the overall mixture stays the same). In indy engines (current, not old) they use multiple fuel injectors to broaden this ram effect. This leads to an amplification of the pressure waves which in turn forces more air and fuel into the cylinder. Depending on the size (volume) of the runner and the density of the air/ fuel in the runner at some rpm you get a resonance of the intake runner. Click to expand.That isn't what velocity stacks are for.Īt WOT the intake valve is opening and closing which creates pressure waves that travel back and forth through the intake runner. ![]()
