Default homade 3k washer 12 valve

I have heard that you can put a washer on the governer spring to get 3k. Does anyone know about this? If so can give me good details and maybe pics? Also will it hurt anything?

yes it can be done, and I don't recommend it. reason being is that i have done it before and it worked flawlessly, and the last time i did it i didn't get the washer seated correctly and it cost me a $1300 p-pump.

if it were me i'd spend the $95-$100 to get the springs to do it right than skimp and then have to buy another injection pump......

I've only done research and haven't tried it yet, but can't the stock springs be tightened down a few notches without hanging?

As Benjamin said spend the $90 and get the kit that way youll get the springs for the 4k kit also. $90 is alot better than $1300. Plus you might as well put the 4k kit in as your in search for a larger turbo and the 4k kit fuels harder than the 3k which will help in spool up time also.

no need for them unless you are going to a 4K kit....stock springs are good to 3200 RPM or so....even then a 4K kit in an auto will not get above 3200 unless you are holding it in gear.

I am not sure why on a street truck anyone worries about the 60 lb valve springs as 99% of the time there is no place we can wind the trucks out hard enough to utilize them anyway.

Throw in the added fact that most ALL 12v trucks HP/Tq numbers drop like a stone off a cliff above 3g's anyway there is not much reason to live up there on the highway.

Now,if your pulling/drag racing then there may be a chance you need them.
