ESS VT3 Supercharged - Update after almost 2 years and 15K miles...

I'm pleased to report that after almost 2 years and 15K miles on the ESS VT3, all is well, the car is running strong and has been very reliable for the amount of horsepower it is making. The built motor with drop in pistons and rods, has never burned any oil between changes and drives just like stock out of boost, the DCT is holding as well.

The VT3 over the last 6 months, with the 12/13psi pulley's, has dynoed between 670-700whp consistently, it's been to 6 events, 4 Airstrips and 2 Big willow track days, and as of September it is now my daily driver. Since I've got the car back from ESS, we have made a few changes to the fuel system, added a few more bypass valves, and as I've posted before the car has had a few issues come up, mostly at these airstrip events, all very fixable though.













At the past two SS3 Airstrip events, while going WOT through all the gears, the manifold has been lifting. Also during WOT runs while shifting at redline, it felt as if the car was shaking/vibrating excessively, and at the most recent NFZ event, I had some misfires. Even with these issues, while frustrating, the car managed a 166MPH trap speed at two different events! On a clean run, 170MPH should be attainable with 13psi, in the 1/2 mile. Some may wonder why not turn up the boost? While it's certainly possible it's not pragmatic or wise to do so on the stock DCT. I have no desire to blow a DCT tranny, it's not worth it. If they ever came out with a tested viable upgrade, only then would I consider it. Regardless a 670 - 700whp reliable daily driver is pretty awesome.

Fixing the issues, the DCT shifting at WOT vibration/judder took awhile to diagnose, a few shops that looked at the car thought it might be, lowering springs, subframe mounts, etc. It wasn't until I took the car to EAS and after a few WOT runs did Steve@EAS know what the issue was, the DCT was causing the excessive vibration/judder. Tom@EAS suggested that we re-calibrate the DCT clutches, he had the tool there to do it, after recalibrating the DCT clutches, the vibration/judder has gone away significantly, I've been impressed with EAS, their techs and the ability to be a full service shop with the proper equipment to do so, thanks guys.

The manifold lifting on WOT high speed runs seems to have been rectified as well. We added two Forge type bypass valves to relieve the excess pressure from 11+psi, one in the back where the ICV hose is, and one on the discharge hose between the Supercharger and Manifold, this seems to have done the trick. Pics below -

Rear Bypass valve -





2nd Forge Valve -





During the last Airstrip event, NFZ, the manifold didn't lift, , but unfortunately the car had a misfire issue during WOT.

Rectifying the misfire issue seemed to be as simple as changing the spark plugs, however while doing so I found in cylinder #4, the spark plug chamber and coil pack were soaked in oil. This is most likely what caused the issue. The spark plug tube that goes between the head and valve cover has a rubber/gasket on each end, the bottom portion where it fits into the head was torn, and oil was slowly leaking in and eventually filled up the chamber over time. The spark plug tip and electrodes were completely free of oil, and all the old spark plugs looked great. After finding this issue, and changing the plugs, no more misfires. :thump: The tear in the rubber gasket must have happened when the new Red PC valve covers that M33 sent me, went in! Regardless easy fix and a big thanks to M33 (Zim) for the new Red Valve covers.

Here is the spark plug hole/chamber that filled with oil -



Here is what it's supposed to look like -



Here's some before and after pics of the Red valve covers, on the originals the paint was peeling.



New cover from M33 in place -



We also changed the fuel system, from two aftermarket pumps to the stock M3 pump and another BMW pump, this setup has been performing perfectly and I can take the fuel all the way down to reserve and not worry about starvation issues. The motor has plenty of fuel, solid fuel pressure and the AFR gauge reads 11.3 - 12, even with a 30% mix of E85 as well.

Here's some pics of the modified fuel rails, pumps, etc.




















I decided I wanted the car to be a little more quiet, I'm getting old and the neighbors were getting upset, lol, here's a few pics of the stock exhaust with the EAS Black ceramic tips -





Here's a BS report:



The VT3 is a blast to drive, Roman and AJ from ESS have been extremely supportive every step of the way and awesome to deal with as well. Also a big thanks to Robert, aka PG who has been very helpful, Izzy (BLUDVL) and and Zim as well. Loving the car, and can't wait tell the next event.

Good stuff. Seeing how strong the clutch packs are in GS7D36BG, is it doable to swap those in GS7D36SG?

Thanks Brother, good question on the DCT clutch packs, I'm sure someone will experiment with this eventually.

I don't see the reason for the extra Blow off valves, esp @ only 11 psi. (still don't get why the new AA kits use 3??)

One should me more than sufficient.


I have no doubt your still using the shitty OE clamps on the iTBS and that's whats causing lifting of the mani under boost. I would have prefered a brakcet to hold down the intake or better clamps (think t-bolt) on the ITBS if you can fit them.

Nice update Drew, ESS VT3 is no joke and you are bound to run into little problems like you mentioned - i.e boost leaks.. and such. Good to see how reliable the S65 is, even on a nice amount of boost.

I hear you and use to feel the same way, but the single Vortech bypass is not sufficient in this case, a larger Tial type BOV might do the trick, but I can't stand the noise. We tried different clamps, that's not it. There are only a few cars in the world running 11+psi the majority of them have had this issue. AA actually runs 3 BOV's and one bypass valve, Evolve runs two BOV's. When you go to 13psi you will need a bypass valve on the rear ICV hose to relieve some of the pressure or it will throw a code, and go into limp mode. It appears the third bypass valve in the front has done the trick. I never had an issue with spirited driving on the street, but that is because I don't hit the speeds I do at the airstrip events.

Thanks man, and I do appreciate your thoughts! I forgot to add that the only other issues I've had are I had to replace the alternator and battery.

This is true, I know a few guys that have had them replaced, a recalibration needs to be performed as well.

Using the Autologic they re-calibrated the DCT clutches.

definitely a badass car! crazy that these cars need multiple BOVs/bypass valves when running relatively moderate boost.
congrats on the ride; any plans to take it to the 1/4 mile with some slicks?

Awesome awesome awesome!

Not sure if I am remembering wrong but did you used to have an RD46 stroker motor SC'd before you went to the VT3 setup? Maybe I am thinking got someone else...

Thank you! I used to take the car to the drags quite a bit, I believe I still hold the NA record, 11.8@118MPH, I may give it a try now with this setup and some drag radials.

Congrats on getting this thing dialed in Drew. With it running 100%, it should be an absolute beast! I mean, at the NFZ event I handily beat a couple cars that previously trapped at 130 in the 1/4 mile. And you flew away from me! Hope you can go the Famoso event to see what you can trap now.

Awesome journey and write up man!

Raising the power bar is not an
easy task, it takes patience and support to achieve and it seems like you have a good group of friends and support from the ESS guy's!
Look forward to your progress & keep us posted !

I have no doubt your still using the shitty OE clamps on the iTBS and that's whats causing lifting of the mani under boost. I would have prefered a brakcet to hold down the intake or better clamps (think t-bolt) on the ITBS if you can fit them.
I agree. The manifold should utilize better clamps to prevent the lifting. Either a support bracket at the rear of the manifold, or weld on v-band flanges onto the factory throttle inlets and v-band flanges on the ESS manifold velocity stacks and secure them this way. It is a leak free and service free solution.

The VT3 over the last 6 months, with the 12/13psi pulley's, has dynoed between 670-700whp consistently, it's been to 6 events, 4 Airstrips and 2 Big willow track days, and as of September it is now my daily driver. Since I've got the car back from ESS, we have made a few changes to the fuel system, added a few more bypass valves, and as I've posted before the car has had a few issues come up, mostly at these airstrip events, all very fixable though.







At the past two SS3 Airstrip events, while going WOT through all the gears, the manifold has been lifting. Also during WOT runs while shifting at redline, it felt as if the car was shaking/vibrating excessively, and at the most recent NFZ event, I had some misfires. Even with these issues, while frustrating, the car managed a 166MPH trap speed at two different events! On a clean run, 170MPH should be attainable with 13psi, in the 1/2 mile. Some may wonder why not turn up the boost? While it's certainly possible it's not pragmatic or wise to do so on the stock DCT. I have no desire to blow a DCT tranny, it's not worth it. If they ever came out with a tested viable upgrade, only then would I consider it. Regardless a 670 - 700whp reliable daily driver is pretty awesome.

Fixing the issues, the DCT shifting at WOT vibration/judder took awhile to diagnose, a few shops that looked at the car thought it might be, lowering springs, subframe mounts, etc. It wasn't until I took the car to EAS and after a few WOT runs did Steve@EAS know what the issue was, the DCT was causing the excessive vibration/judder. Tom@EAS suggested that we re-calibrate the DCT clutches, he had the tool there to do it, after recalibrating the DCT clutches, the vibration/judder has gone away significantly, I've been impressed with EAS, their techs and the ability to be a full service shop with the tools to do so, thanks guys.

The manifold lifting on WOT high speed runs seems to have been rectified as well. We added two Forge type bypass valves to relieve the excess pressure from 11+psi, one in the back where the ICV hose is, and one on the discharge hose between the Supercharger and Manifold, this seems to have done the trick.

During the last Airstrip event, NFZ, the manifold didn't lift, , but unfortunately the car had a misfire issue during WOT.
Congrats Drew. Glad she's running well. However, why is the 2nd bypass valve being plumbed back into the charged section of the intake? Why not just plumb back into the pre-charged intake tract along with the main Bypass valve.

And Drew, the differential bushings in your car are on their way out. There is a lot of deflection occurring there last time I saw it. The car is making double the WHP of the stock M3. Certain drive train components are simply not going to last or do their job correctly.
