Any time I have heard audible knock on stock seals, you know that rocks in the engine sound, I have a broke seal and the rest are generally warped. I have owned my Fd for 10 years. I have broken 3 stock seals over the course of owership

After market seal i have, have yet to break or warp. They have had that rocks in engine sound many times tuning to 20psi on pump gas. NO breaking or warping. Last engine, which is apart at the moment has a corrosion issuse which lead to a water jacket leak. Apex's are flat and fine.

Period, you aren't bleeding from the *** are you??

 

And here is for some visual stimualtion. I wonder which seal in this picture is stock and which one took heavy knocking, long term high load abuse and lasted until the coolant seal let go??

 

Why are your motors hitting 20 psi to begin with. Ever heard of overboost fuel cut? It's this great thing that saves motors from overboosting. Though, I still do not see your point. We all know stock seals are weaker, I am merely pointing out that the boost is not what breaks them and they aren't made of glass to break so easy either. When I tune a car, I don't care what seals are in it, I tune it the same way but cars really don't leave my hands until I am satisfied with running condition either.

Also on a side note, if you think detonation sounds like marbles in a can on a rotary, you have never heard actual detonation then. But that is another topic and not really important lol

Agreeing w/ the wird as you cannot just turn the boost up. The pfc will need the WOT maps adjusted. Its not worth a chance. As for hearing the rocks in the engine sound glad your not tuning my car.

 

I want it to run 20psi. I have fuel cut set at 1.5 bar. I have enought knock to dent rotor faces, wana see those pic's. I was trying to find the limits of pump gas, timing advance and a/f ratio, its nice to have a seal that can take abuse instead of breaking... like stock... I am not god of tuning and I make mistakes.

No not marbles in a can, rocks inside the engine, or some one hitting it with a hammer.

 

No I am not. I am not familiar with that. What is the advantages and how much does it cost to install it?? Thanks!

 

Here are a few things that used Auxilary injection in history and a Wiki write up about it. A basic system costs around $400 and go up from there. There are two bacic types, mechinacal, which uses boost pressure to pump water pre turbo/supercharge. Electric pump is the other type. It uses an electrc pump to pump water either pre or post turbo/supercharger. There is an Auxilary injection section on this forum that is a little more Rx7 oriented

F-4X Phantom- Proposed high-performance reconnaissance version with HIAC-1 LOROP camera for Israel developed under program Peace Jack in conjunction with General Dynamics. Water injection was projected to give the aircraft a top speed in excess of Mach 3 (over 2,000 mph (3,200 km/h) at high altitudes). The water would be contained in a pair of 2,500 US gal (9,600 l) conformal tanks on the sides of the fuselage spine. State Department became worried about developing an aircraft with performance similar to SR-71 Blackbird and offensive capability beyond anything in USAF inventory for a foreign customer and forbade its export. The proposal was then modified to RF-4X with the camera in the nose which removed offensive capability. However, USAF withdrew from the project over concerns that a high-performance Phantom would jeopardize funding for F-15 Eagle. Without USAF financial support, Israel settled for a simpler and less expensive F-4E(S).

The B-52 "B" models were powered with an updated type of the J57 engine, delivering as much as 12,000 pounds of thrust with water injection. Thirty-five B-52C aircraft followed. These had 3000 gallon drop tanks, improved avionics, and a distinctive coat of white antithermal paint on the undersurfaces.

the P-51H used water injection for bursts of up to 2,000 hp.
