I will get the manifold pictures up soon , wife broke the I pad so I can't do it just yet. What power am I after , no idea. E30 with an s50 (300bhp) go really well so anything like that would do. Suspicious it will be more like 450 going on what I've read.
Had to cut the chassis rail to give the collector some much needed room. This will be boxed back in when it's finished
I can say Thomas really does an awesome job and knows his stuff with manifold design. I love my car and never before have I let someone else work on it but I 100% trust his work . Don't by cheep eBay crap , get this man to build you one from scratch. Do it once , do it right.
WOW great read this. I have been following the red touring project in PBMW as well. Great work I am going to have to come see you guys when i start planing some engine work on my car i think.
Calculations for the runner length on the manifold . Straight on the bench . Man style - - - Updated - - - More off the collector
All the design work is done now and it's just a case of welding the runners up. Sticking the whole thing together. Then the fun starts with the 2 waist gates Thomas has got to squeeze in there , oh then a 3" down pipe with the waist gate pipes in it on twin v band clamps . This means it can be quiet for racing/ track use then asbo screamer pipes when needed
