s not being a viable venture for their project budget and didn't think an s50 swap or 6 cylinder variant was worthy either (not gonna open this can of worms).
The brake booster mod seems simple enough along with the pulley swaps to run the mid gen m44/m42 serpentine belt system.
I would imagine a car mapped off MS with an AFM delete along with a better fuel management system would be beneficial. Seeing that this system is made to be a conservative, CARB legal modification, I wonder if 20hp is lying elsewhere to be gained and what the extra cost will be?
I wonder how this setup will take to a long header design with a high flow cat set up along with an injector upgrade as mentioned above?
The cons of the roots blowers as being less thermal efficient, having a higher parasitic loss are the only ones of concern to our application based on them overcoming fitment and clearance issues relatively easily. Anyone agree with me.
So now the question would be, build up a motor'd up bottom-end and top-end style motor like Febi or Tim S, Go with a DA style set up for approx 5-6k (factoring in petty upgrades needed not included as we all KNOW, no project is as simple as A-B-C). It's evident it takes almost the same amount of money to do this but the level of technical complexity and long term effects are yet to be seen. Monetary investment seems to be relatively the same surprisingly.
I am curious to see who will go with any of these set ups and take them to the track for SCCA or BMWCCA racing as that's where the true durability and competitiveness would show. Perhaps and aftercooled DA m42 :cool: ?
What I gathered was that while they could do those other cars, they did not want to, besides after talking to other owners, it seems the 6 does push a lot more and the m3 is heavy. There is some serious differences in handling and the way they drive in general.
As for the blowers, I have been looking into this for a while, but figured teh computer would need work adn such, apparently not. I have been loooking for an easy way to do something similar as well. My brother and I have always wondered about the Eaton M45 and M62. The 62 is used by Pontiac and can be had rebuilt for $600. Used for $200. It is however a bit large, but would be useable. The m45 is used on the Mini Cooper S, it is a bit harder to find, and there was no buy it nows so we are not sure what they are averaging at the moment.
With some slight changes to the upper intake we igure the booster would not need to be moved and you could even use the stock intake boot and AFM. Also we wonder if they could have just changed the pulley on the A/C compressor, it "should" be in the proper spot if you can.
And while roots are less efficient, they do the job, and have instant power.
By the way the:
M54 is equal to adding .75 liters to your engine.
M62 is 1 liter.
M54 is perfectly sized, the M62 is a bit oversize, but it is used on 1.6 and 1.8 Miatas, and the new Cobalt so it should not be an issue.
Be aware there are 3 different snouts, and the Mercedes version has an electronic clutch similar to an AC compressor so it can be turned on or off (could be interesting to play with).
Based on GRM, add the 19 pound injectors, an adj. pressure regulator, and reset the computer. It should be ok without re-programming as long as you stay with about 6 pounds of boost which is good for about 180hp.
The bottom end should hold together for it. As for other mods, the head/valve work Febi had done could be added to make it better, but the rest of the bottom end should be ok.
So, I may be looking at a welder here soon
Sheet metal blower intake anyone?
