I decided to pull this component out of a parts box and install it on my water-methanol injection system to see if it will help with smoothing out the fluid flow to the intake.
Aquamist Anti-Surge Accumulator “Water Shock”
The part is called an anti-surge accumulator. Aquamist offered it with the 2D system that I used to operate. It helped to smooth the fluid supply from the race pump and was also supposed to help improve the flow rate from the pump. I’ve noticed some oscillations in the reported flow rate and thought this might help to smooth the supply. The Aquamist race pump had much lower flow capacity than most of the currently available pumps, so I’m not concerned with any flow rate increases that might come from using this part. In fact I generally run the pump I have around 30-45% duty cycle and it cools well at that flow rate into a pair of 0.7mm Aquamist nozzles.
I’ve installed the ‘water shock’ after the pump and prior to the water flow sensor.
Things progressed this weekend with the TTE550 turbochargers, but it’s been a bittersweet continuation of the project with the sudden unexpected passing of “Daz Dillinger”. Daz is a person with whom I have partnered on several projects since we were first introduced several years ago. It has been his knowledge and generosity that have provided the foundation upon which this project, as well as others, have been built. I will have more to say about Daz’s work with me in a separate posting.
The first drive with the TTE550’s has been successful, although with two issues to address. First was a high pitched siren sound when boost hit about 20 psi, something I immediately thought was a boost leak. After hooking up the boost checker I confirmed my hunch, that yes there was a hose clamp on the upper passenger side intercooler that was not tight enough. It was a relief to have the problem be located in such an easily accessible location.
The second issue, which is a known obstacle to overcome with the changing out of turbochargers, is that the TTE550’s use an 8 psi-preload on the wastegates, and the FT21’s used about 14 psi. Thus the tune now will under-boost on account of the wastegate differences.
Today the second TTE550 was hooked up and the engine put back into the car.
I’m finding a suggestion to install the axles while the engine is a couple of inches above the mounts, and the transmission brackets a few inches above the tranny mounts, to be a good one. Turning the wheel fully left or right depending upon the side being worked, allows the axle to go in, and with the engine hanging from the hoist there’s enough freeplay to push it slightly if needed. This sped up the process of reinstalling the engine substantially.
