Duramax Larger Injector Discussion

No.. Not unless you're changing the whole design..

IMO the race valves shouldn't be used. There should be some sort of relief in the system to get rid of spikes when the engine goes to 0 throttle quickly after acceleration.

The dodges are very prone to cracking bodies since they only have 6 injectors to spread the pressure over and have a bypass valve that.. pretty much never bypass'.

Well in the beginning they were marketed as 70mm's so that other mfg's wouldn't notice the wheel size and be clued in as to what it was made from.. But elite diesel cut and pasted the compressor maps straight from Garrett's site onto theirs so that pretty much gave it away.

So.. the 64mm Cheetah is a Variable 4088, and the old 70 is a 4094. Now I have 70 (2.8) and 76.2 (3.0) comp wheels. So I had to change the names.. Pretty cornfusing ...


Larry knew what he was getting though.

Interesting! :secret:

i have logs were i went to 0-10% and have watch actuall rail pressure spike 5-7k from a sustian 23,000 then drop down

The factory sensor is able to measure transients very well either. So it may be spiking much much higher without our knowledge.

Bringing up a really old thread but would like to know if anyone ever came up with conclusive data as to larger injectors are able to save hard parts for stock motors?

Brayden what if the high pressure side of the fuel system had a shock absorber instead of making a relief valve dump it back to the tank. Example would be a hammer arrester that is used on plumbing systems for quick closing valves I.E. washer, dish washer, and commercial urinals and toilets. Not sure if a if a rubber bladder could deal with that type of pressure though but maybe somebody smarter than I could make something like this to "absorb" pressure spikes instead of dumping the fuel?
