Nice work, looks like a lot of work has gone into that.

hello, we have talked on rennlist/944sverige before, my 944T is also getting vems, but seeing as I'm a cheater I'm paying the guys at dp-engineering to do it :)

you should no doubt see some wicked power numbers, and I think thoose injectors might even be on the small side, especially with E85.

if you haven't changed ic yet I posted on my thread on 944sverige/rennlist about the rx7 ic that barely fits, but has a whopping 2-3mm clearance so it does indeed fit, might be something to add to the list. and as you probably know your airfilter isn't ideal :)

You will need about 30% more fuel to run E85

Yes, there's a larger IC:



I'm very aware of my air cleaner location problem, and I'm working on a solution to that. Cleaner will stay there, but it'll get fresh air. We don't have here E85, so I just have to do with Shell V-Power.

EDIT: The air cleaner in that picture is not there anymore, it's been replaced by a bigger one 6 months ago. I'm also working on a version 3 of inlet manifold, it'll be somehow smaller with 3" IC pipes, reversed IC flow and the air cleaner will be turned left behind the headlight.

A small update, if I may. Most of the bugs are solved, idle area of the VE-map is more or less adjusted and ICV works now, keeping 900+/-20rpm (warm ) idle. So there's a chance I'll be driving this summer.
The next step is to take the car to dyno for engine break-in and ignition/VE adustment. This because here's winter now and I want to get the car running and adjusted for the beginning of the season...
