Alpine White Eaton M62 Build

[Daz3]

It will be a beast when the eatons bolted on I suppose I really should make some more effort to get to some meets next year if it's all ready which it should be

One hell of great looking zed! In my top 3 on the forum with Liam's Evolve Z3M

Bit more progress today got the bottom pulley done!
These are the dimensions for the 3mm spacer plate 48mm radius for the inner cut out and 65mm radius for the outer.

And the dimensions for the mounting plate 5mm
Same outer radius of 65mm
Centre hole of 30mm to fit on the PAS pump
25mm radius for the 3 mounting bolt holes with 43.5mm between the holes drilled 9mm
56mm radius for the outer bolts to mount plates to the pulley with 56mm between holes drilled 6.5mm

Plates next to each other

How they mount in the pulley 3mm shim plate first followed by the mount plate this gives the correct offset to align the belt.
The original belt is long enough to use as the inner pulley is 15mm larger in diameter to the standard pump pulley.

The pulley is being taken to a local engineering firm for balancing.
Next up is the supercharger mounting plate.

Great progress, be interested in your project costs, to see how it compares to DASC on the 1.9, might be a more viable opportunity to the DASC kit.

 

[Daz3]

I think it could be done for under 1k including mapping just depends on what shiney bits and pieces you want

 

[Daz3]

First trial fit of the charger mount just a couple of mods to make and weld a couple of gussets in and we're good to go!
Also ordered a tensioner and wheel last night so can add that when it arrives.

Re: My 2.8 Alpine White III Progress

Shanty: I will be making the exhaust myself I'm a welder/fabricator about time my job came in useful

Liam: Thanks for the splitters there going to look cool. I haven't done all that since I got in but seeing a couple of cars spurred me on into taking a couple of pics

I've been looking at all your pictures and work and I'm a bit taken back. Very impressive. Sort of makes me feel almost helpless. I've always worked on my own car but never body or paint. I always wanted to try but feel I don't have the proper facilities for it. I'm sure being a fabricator imparts a wealth of knowledge toward working your own car. The thought of all that almost scares me. Looks like a great job.

 

[Daz3]

Just about finished the charger bracket now and mounted the tensioner. I just have a couple of support brackets to make and then it's just pipe work

Hi Daz, have you any idea of the amount of extra BHP and Torque this setup will achieve. Or are you working to a specific target?

By the way, the car looks awesome, can't wait to see it in the flesh.

[Daz3]

To be honest I haven't got a clue I'm aiming for 300 but anywhere from 270bhp I'll be happy. M50 manifold usually gives a good chunk of hp plus a nice free flowing exhaust and remap should be good. Although if I'm honest I just want the noise

Are there any more bolts holding on your mounting plate or is it just the two we can see?

 

[Daz3]

Are there any more bolts holding on your mounting plate or is it just the two we can see?

No there will be two more support brackets which I'm making over the weekend. Got the main mount all welded up today and is pretty sturdy just on the two bolts you can see but will flex if the charger was spun up.

 

[EnthuZiaZT]

What boost will the supercharger give Daz, can you adjust the pressure?

Mike

 

[Daz3]

The boost pressure varies depending on what pulley ratios you run. The charger produces so much boost at certain rpm, however the faster the charger spins the less efficient it becomes, basically

 

[z3cade]

Hurry up Daz!!! I want a race lol!

 

[zedonist]

Looking good, my only comment on the SC to bracket is that you appear to have three spacers on the top, and a slot in the plate and then a free nut, i think you will find it hard to put enough torque into the joint to stop it slipping and shaking loose. As i counted 7 slip faces, it might be worth welding the the nut to the back plate and fitting correct length single spacers, what grade of bolt are you using in that part of the application? would suggest 10.9 minimum with a grade 8 or 10 nut.

 

[Daz3]

I'm having some spacers made up, the three together are there purely for mocking up. Once I get the charger in the right place I could weld a nut to the back and the spacers to the front. It's a bit trial and error really. The bolt holes in the charger are m8 but quite sloppy so I've been thinking about drilling them out to take and m10 as for grade yes I'll run a high tensile. Thanks for the comments I'd sooner people have input and suggest things that may be overlooked or wrong. Do stainless bolts come in higher tensile or is it too brittle a metal.

 

[zedonist]

Yes stainless is graded by tensile strength, but will only provide the same performance as a high grade carbon bolt, the only benefit would be corrosion resistance, and to be honest under the bonnet, carbon steel bolts are perfect, so no need to go stainless, what you do need to avoid though is contact with dissimilar metals I.e. Steel with aluminium, stainless with carbon steel, as you end up with galvanic corrosion and premature failure, so best bet is keep it carbon steel all through.

Just keep the number of mating surfaces to a minimum and ensure you torque the bolts up correctly, unfortunately yours is an un known application, so it is best to use a higher tensile bolt to ensure you get maximum joint load so grade 10.9 or 12.9 is best and torque to 85% of the bolt proof load, as a rough rule of thumb.
