Stratos Evoluzione, Carbon Kevlar body, T45 spaceframe build

There is quite a bit of space in the back of the standard bodywork if you go light and exclude the internal structure for the boot - and then ventilate it.





Just me doing this then




And maybe my mate CJ

So spent a lot of mental thought and double triple measurements, quite exhausting
At this point to fit correct length A-arms and mimic the rear suspension geometry of a 037
I will shift engine over to the Left 80mm and the CV flange centerline forward of the wheel center by minimum 40mm possibly 50 ? 60mm is 2degree away from maximum articulation, so 50 should be safe as that angle plain will not change except chassis engine flex which should be minimal
I am rotating the front of engine up to bring the cam covers somewhat level, so I can go IDA Webers
This also gives plenty room to have front track bar of rear lower A-arm to mount forward of and possibly a bit under the front right of oil pan, which will be cut short as the engine will be dry sump

At this position the theoretical center of the engine cyl’s 2-5 will only be 35mm to the right of centerline Carbs should look pukka

I have cut some box section to be my engine set up jig stand, I will join parts together to eliminate risk of engine toppling off them 😀

I have come with another ignition option of this Turbo blow thru IDF’s as I really want an analog car not a EFi Digital
Racing HEI Buick V6 distributor (even fire version) they are self contained, coil in cap only need power wire, cut down housing weld on a machined bearing housing and take drive off front intake cam sprocket ie like the Dino, and yes has correct rotation too !!!

I have seen that company once before
X-Sport racing who I am getting my body from also have full molds for RS200 6R4

I have been analyzing the last 6 days exactly where but the engine, the actual balance point is somewhere close to center of last 4 cylinders
60mm Left offset visually looks good but it will be heavily weighted Left I don’t believe I could compensate with enough parts placement on right to correct it.
I will probably end up with just 25mm Left offset ?visually not as good but will be much closer to equal weight balance
I have moved the engine forward another 10mm so now it’s 70mm total forward of wheel centerline
Still safe CV angle 15 degrees

Thanks, yes I think I have, I have see a few different, I follow 037 FB resource group, there’s lots of info I have obtained from them.
I will not have 037 narrow rear frame width very long A arms on the rear, I can obtain the same static geometry with a little bit shorter arms, however I can use less off set wheels to gain some A arm length over normal Stratos
037 had a narrower rear Track Width v Grp4 Stratos so theirs a bit of give and take

Yes I have because it’s LHD it makes it worse, I am a flyweight but still I will need everything I can mount to be on the RH side hence screw looks engine has to go as far right as possible I believe engine is balanced LH RH if CV flanges are centered but that is a little too far RH so probably 30-35mm LH will be fine so I’m mainly counter balancing my weight

While I wait on Roof Roll bar from bender, I sent off the Alfa CF2 3-1 headers off to media blaster, they are a stainless look good enough for Turbo manifold, though I might change collector to merge type ?

Onwards with something else “IDF Intake Manifold”
Lots of measuring later I cam up with this skewed/ angle carb design



50x3 wall aluminum tube bore = 44mm for 44 IDF carbs, because of the tight 1 x D diameter radius, the bend will be created with “pie cut” tube
Sections 2 x 15 degree segments / intake runner







Cyl intake flanges out be being water jet cut, gave the company 1 port of intake gasket as template which I have to pay CAD DFX file set cost + the flanges in 8mm thick 6082 T6
The injector cut out is eliminated on the flanges, the intake port opening will need profile grinding from flattish oval opening to just off round.
Weber carb IDF flanges are available from Danst Eng’ already ordered

The carb flanges will be mounted to steel plate
I will used the engine for alignment
Intake will be matched to port using close fitting bolt holes so they line up with minimal wiggle room
As the carb flange goes on last it will all be perfect

Yes you could have 1 piece / cyl head however you have to also consider access to welding everything
3 manifolds makes everything easier access

Removed engine, cut hole in jig for Differential clearance do can set engine at its final level and lowered position
35mm offset to Left = balance point at centerline
Drive flanges 70mm forward of wheel = 15 degree CV shaft angle
