ESS VT3 Supercharger - Low Compression M3 S65 Engine Build Has Begun...

[per]

How about a "congrats" to ESS on the VT3 build? [/QUOTE]

Yes , It is realy going to be interesting to see what this motor is going to perform, I will save my congratulations until We see the results

I have a 92mm pulley, the normal has 95mm i believe.

omgggggg can't wait! haha

Long time no talk drew. Out of curiousty, why didn't you go just shift to GTR and put that same a mount as you did in both enginers and spend that towards the GTR?

Hey man, good question, I thought about the GTR, but it would have cost more to buy it and then to mod it, especially if I decided to build it. My car with the Supercharger on the stock block, did very well against full bolt on GTR's, minus a turbo upgrade, and 60-130 it was faster as well.

I have several friends with modded GTR's, love the cars but the upgrade costs are pricey. My M3 is just about paid off, and as Schnell said there's not many Stage 3 built motor E9X M3's and I have a high amount of confidence in ESS to do this type of build on my car, where as before I really wasn't sure this was something that was a viable option.

Your car will be happy to get back to Cali, out of the heat.

I will be picking it up, when I drove it out to ESS it was 110, when the family and I drove back the next day it was 116!

vids???

ESS demands & is commited to Perfection and that's just what Drew's gonna get , there is no doubt in my mind that this thing is gonna be one unique M3 !
Take some videos if you can Drew to share with us ( share the excitement ) !!

Drew - see you at the alley?

You haven't offered any simulations or any real-life data other than stock cars in controlled environments with professional drivers. When you double the horsepower, I'm telling you that everything changes. I'm sure you're mulling over the data posted above and looking for something wrong. It will be interesting to see what you come up with.

Sorry been super busy with work and life outside work as well.

Please start another thread. A good topic might be "the importance of DCT for drag racing" or something along those lines. I promise I will have a closer look at your results and reply with my own simulations.

One point does immediately stand out though. Your losses are almost for sure incorrect. Incorrect based on real world validations as well as text book values. Run your losses with a standard power car and see how far off you are from the best reported magazine times! If your losses are off (too high) but results are right then you are right for the wrong reason and thus a likely conclusion would that true power is actually a bit higher than your input power.

At first he laughed and then added that everything from shift speed to gear ratios affects the trap speed. So just to satisfy my own curiosity, I ran CarTest simulations on a bone stock DCT modifying nothing but the final drive ratio from 1.50 to 3.62. CarTest predicts a 7MPH trap speed difference between these two ratios. How is this possible if gears don't make a difference in trap speed?

You are surprised that a 200% change in final drive makes a 7 mph trap speed difference? What would a 200% change in power do? That is the real question. I've never said gearing and shift speeds do not matter because they do. However, no one in their right mind would alter a FD in a street (or drag) car from 3.62 to 1.50. Both gearing and shift speeds (and a variety of other factors) play a minor role compared to power for both times and traps. Power to weight is what we call a "first order effect" whereas most other factors are 2nd or 3rd order or less meaning a similar relative % change in those items will have a significantly smaller effect on results. It is basic physics...

physics gotta love it or hate it. I will talk with some people at work and try to make my own program for some simulations.


Drew you car is crazy and you gotta bring that beast to the east coast please.
