Has anyone tried making these." rel="nofollow -

I printed some today  in pla+, they're for 51 mm  throttle bodies. They came out ok, so I've got some petg on order to make a proper set to trial.

The link doesn’t work but stepicenti has been making dual height stacks for quite a while now.

Yes lots of people jumped on the back of stepisenti although people were making theses with standard parts a long time before 

Ensure your plastic is petrol resistant as some spray back make determinate them and could fail and get sucked in the motor

Always thought that shorter stacks more top end longer more bottom or mid range.iv got the carbon dual stacks and can say they are very good in both areas Thumbs Up

I went for a good test ride last night and now it will pull a higher gear. 6th is good to go from 4000 rpm onwards, sometimes even as low as 3500, whereas before 6th was more of an overdrive gear and I never used it. Now I'm riding a wave of torque in any gear, it doesn't bog or suddenly come on the power, it just pulls. Very linear. Great improvement.
Yes, I've already got a modified collector, mille air boot, standard filter and airbox, Gabro chip.
