@ Bruce I think I'm going to install a spy CAM near your lift.
So please don't knock it down and try and keep the lens clean for me.
This is so I can keep track of all this new hardware you keep coming out with.
Nice work....
I will call you when some of the traffic dies down and you have a minute.
Thanks again for helping me out.

Jack-
Your injectors are here and I am waiting on your fuel rail from Germany to show up so I can get the fab work done!

I know this has prolly been thought of or even done but could we just change the fuel pressure regulator to say up the psi by 5-10 psi?
Kit looks nice Bruce but what about the people that dont need to go over kill and just want to make there mildy modded or even stock cars safer?

There is nothing overkill about this set up. Any modified M113k will exhibit a lack of fuel pressure/volume reaching back to #8 on high speed runs. This is more about a level of protection and piece of mind when doing these runs. Regardless of who is doing the tuning, any mid to highly modified M113k's will have fueling issues and that is what the TTM Injector & Fuel Rail Kit addresses and corrects.
It is more about saving these engines, rctifying the fuel starvation issues and having a consistent fuel pressure and volume to ALL 8 CYLINDERS!! The tuning will be even better since we have much more consistency throughout all of the injectors.

Like Bruce said, we've talked lots of time(class act all the way around) I personally feel that my set up is way way to complicated and over thought, But when you start from scratch there is allot of trail and error. Once I get it figured out it should be nice.
I really like what Bruce has come up with, The package of injectors and modified rail make sense, its effective and well thought out. I think it should be a must for anyone serous about making power and doing it safely.

This is now in the tuners hand to scale for the injectors and the new fuel pressure/volume characteristics.
PS Spy camera is up and running Ron!

This is a great post and leave it to Bruce to come up with yet another way to squeeze more power out of these cars. Gotta appreciate how he approaches these cars and thinks 'outside the box'.

i would love to get it. but i already paid for my new CLS63 edition1 with all the options and performance options on the list. about 180k USD
so i think i will be selling my E55 very soon. i will miss 600lbs TQ on the wheel.

The tune has to be scaled for the injectors and also the consistent fuel pressure that was missing with the stock rail coupled with stock or larger injectors.
This is now in the tuners hand to scale for the injectors and the new fuel pressure/volume characteristics.

Our cars are not new and mods have been out there for a very long time now.
How is it that suddenly we all need this?
500whp was a number easily achieved with just pulley, tb, headers and tune. And many have ran with this setup with no issues, so again how come now?
Many have past those stages of mods, yet no e have really come forward to show anything about this.
I personly suffer when going all out on high speed runs and coming to a stop, of the car stuttering and shacking, as if it runing out of fuel. However I was told this is somthing related to the 82mm tb. So my question now is, is it due to fuel? If so how come it happens when u come to a stop?
Last question can this be tuned easily or are we going to face issues with incorporating this?
Thx

your tuner should be able to scale the injectors to match the modifications on your car.
Bigger injectors help the car to run safely. You may be good with stock injecots but you are always taking the risk to going to lean. So it boils down to are you will to spend to money to run fast safely.

Ok I have a few questions.
Our cars are not new and mods have been out there for a very long time now.
How is it that suddenly we all need this?
500whp was a number easily achieved with just pulley, tb, headers and tune. And many have ran with this setup with no issues, so again how come now?

Ask any tuner and they will tell you all about these fuel starvation issues that the TTM Injector and Fuel Rail rectifies.

i datalogg via dashdaq and zt-2 wideband and my afr is great with jerry's tune. is there a way to tell if the rear cylinders are going lean at wot? i would also need a way to install my fuel pressure sensor for my dashdaq as now i use the end of the fuel rail

The whole premise to this fuel rail set up is to help rectify the fuel starvation that happens to these high horsepower M113k's on the left side (#5-#8 cylinder). It is not just #8 but also #6 and #7 too. The fuel rail builds pressure from the ends of the fuel rail(#1 and #5) so when the stock injectors duty cycle is getting maxed out, it causes the left side of the rail to starve for fuel which restricts the amount of pressurize/volume in the rail back to the injectors. With the TTM fuel rail there is another ~12" of pressurized fuel in the rail so the volume is increased. With the larger injectors the duty cycle is lower and that gives the rail time to build the necessary pressure but this is also why you need the extra fuel from our rail. The feed line from the pump to the rail is very small in comparison to the size of the fuel rail so having an extra 12" of pressurized fuel and the lower duty cycle with the larger injectors all but eliminates the fuel starvation issues many people experience with these highly modified M113k's.
The injectors are a dual spray pattern which works exceptionally well with the 2 intake valve design head. As close to direct injection as you can get on these engines.

- was finally able to get oriented with the Left and Right side you are talking (just because we are usual to consider Left the side you see when looking at the engine and not the driver's view ..)
- still can't get why #8 should suffer more than #4 : aren't they both at the same, more or less, distance from their respective closed end of the rail ?
btw, can you tell the function of that kind-of a regulator attached to the rail ? .. it doesn't seem a pressure regulator and it even has no connection to the intake for sensing vacuum/boost
I mean, how is in our engine regulated the different pressure/flow requirement when idling vs when WOT?
about these 550cc injectors: I for sure lost some of the long past discussion about these various injectors, so, to recapitulate, how does its capacity compare to the SLR's injector on equal pressure, resistance, etc .. basis (for which had been given different capacities ranging from 480 to 512 and more ) ?
thanks
forgot this: where does that additional rail tubing will be run: above the S/C pulley along SLR style ?
