Re: TPI Long Tube Runner Project
i would love a set of those runners for my ZZ3 TPI project
Re: TPI Long Tube Runner Project
I am making good progress on the runners. I have finished the upper set of runners on one half. I went ahead and took a picture for comparison with a stock set of runners so one can see the difference in size. This gives you an idea of the increase in cross sectional area.
AGAIN, AWESOME WORK!

Re: TPI Long Tube Runner Project
Awesome work, I can't help but wonder why you did not consider a super ram style plenum and revised runner's with this base setup at the time you built it. Would be interesting to see how it performed. Have you revisited this project, or passed it on to someone that continued to develop it?

Re: TPI Long Tube Runner Project
if you should cross paths with this intake again and its owner wishes to sell it. I would quite seriously buy it. out of curiosity, how many man hours and material investement do you think you had in this thing? 80,120 hours of design, testing, and fabricating plus materials?

Re: TPI Long Tube Runner Project
I really do not know how much time was invested. I am lucky that I have a friend with a machine shop and another acquaintance who is a very good welder. So the costs were a fraction of what they would have been. That is what made this project feasible. I do not know where the intake is today.
