Why didn't you opt for larger? The flow surely wouldn't have hurt anything, and the stock Mani has such a huge air gap so plenty of space?
Good question. Short answer is that we'd like to... but we got such a good source on these and purchased in such a significant quantity that we couldn't justify the extra cost. There may be room in the market to support something between this and GC's, but we'd rather crank these out for a good price for the ~600-650 whp crowd (which is enough for most people and stock engines) and continue to improve the GC's. We have a lot of developments coming out, this is the first of many.

Fair cop. Thought you said this was your design from scratch tho..

Also, if you missed the edit, 8.1% not 5!

At least it's finally a better more reliable cheaper "stage 2" option, no more hybrids!

Thread revival... has anyone installed these yet? i am looking for reviews... bit disappointed that these versions dont produce as much power as the older stage 2/2+ but the price is keen!

These will produce the same or more power as the original stage 2. There is no magic, the wheels are the same size on both. Simply need to get these on a car without a bad motor to see good results. We have shipped almost 50 sets so far. Many happy customers. Same thing applies as it always has, and will most likely never change. Happy customers almost never post, unhappy ones do.
