What are your HP goals?

What's your reasoning for twin-charging the car? A well-built and tuned engine, with a proper turbo manifold and properly sized turbo (check out the Borg Warner EFR's), will have great response, tons of top-end power, and much less complexity.

With a forged bottom end, headwork/cams, you should have no problem hitting 400whp +

Perfectly doable with a turbo setup.

Big turbo and anti-lag will still be better than a power sucking supercharger.

target is 500HP, supercharged for the low rpm to extract from hairpin bend and turbo for the streight line :-)

[Mr. Tasty]

fuck yea!

Small update

I ve made my plate for my roll cage in 3mm metal. Need to find a sandblaster to have a body perfectly clean before starting to weld.



Rally season will ended this week so i will have more time to spend on the BMW :-)

Did you get signed up for this years event? The intake you have drawn up, you read my mind, I was working on something like that, but different.

[Pierre_e21]

Hello Jeff no too short for this year, too much job to do + logistic problem to solve to send the car (one month before the race...)
I've read a lot of book to help for the design and also to be not impossible to assemble :-)

[Pierre_e21]

Just received today parts for my linkbear to weld on the control arm. ALl in 25CD4S (4310 i think in USA system metal)

[Pierre_e21]

some news i've received my link bearing for control arme and the pipe in 43100 (6m in 32*2 mm and 6m in 30*2 mm)

Moreover i bought this sheet of metal (42cd4) to machine some parts



and this new things to go to my garage :p
