Theres a youtube video I saw a few years back, guy used a simple process to keep the foam in shape and be able to use the shape he had made. ill see if I can find it and post.
Professional video tutorial from https://www.easycomposites.co.uk demonstrating a step-by-step process for producing a dimensionally accurate, well finished ...
I've been searching for a suitable turbocharger lately, it's been too damn cold at the garage to do anything without keeping it warm continuously
At first I was looking for a Precision 6766, but then I noticed BorgWarner has released their new SX-E series, which might be a notable rival being also a little bit cheaper.
The one I'm interested is the S369 measured at 69/91mm comp and 74/80mm turbine.
I was wondering if anyone is running an older S366 in their M30B35 for reference? I'd like to see dynographs and boost/backpressure charts..
In case there's no info available, I'd probably go for a T4 1.00 A/R housing as my engine will be +10:1 CR revved up to 8k and supercharger will be helping at the low end ;D
Recently I acquired 3D printer for rapid prototyping, one of the first test pieces was our designed BMW M10/M30 rocker arm. Got a few ideas how to utilize the printer with the E30 :) (click to view the video clip at facebook)
I haven't bothered to comment on your FB page or posts to r3v, but that control arm looks great. Any plans for a production version?
Yes, just a matter of time ;D
Earlier I inquired about S300 series turbochargers, but calculations proved there's no big enough turbine housings available, so... I had to look for something bigger. S467 would meet my requirements, but I wasn't sure if it would fit at all. Luckily I found one for testing, with 5" intake pipe:
This is a cast wheel unit with regular comp cover, I'll probably get the billet wheel unit with race cover:
Yesterday I spent a couple of moments looking and turning the turbo in different positions, tried different steel bends and ended up doing two collectors. The manifold will be equal length 6-2 type, I still need to make a turbo flange and get few more bigger diameter bends. But here's a start:
At some point I thought I will never manage to make an equal length manifold, but after few hours things were on the bright side.
Primaries are 42mm pipe which connect to a 3-1 collector, after that there's a short 51mm pipe/transition piece to the turbo flange, all pipes are equal length.
When I see that this thread has a new post, I can't click on it fast enough. Some of the best fab on r3v.
