the hot wire isn't so much to get more voltage to the pump (although that does have benifets) ... it'* more to get the pump the proper voltage/amperage supply it wants/needs

as for the injectors, FPR, rails etc... I should not have to touch them... but I will be keeping tabs on the duty% the injectors are running at through the mods... but remeber motor alone I probably won't break 195hp .. but the pump itself will have to support fuel for about 250hp... as the wet nitrous kit is providing power outside of the regular motor fuel equipment... if anything I might have to change the FPR and make slight changes to the fuel rail and fuel lines for the different FPR to make sure the nitrous Fuel solenoid gets the fuel it needs


the nitrous system I am setting up is gonna to be more costly then most but alot of that is the safety devices and controls I'm installing with it... the cool part is with the rpm based nitrous controller I am using I can control when the nitrous hits .. how hard it hits and how fast in the rpm it ramps up ... this also means I can go up in nitrous jets and closely monitor the a/f, KR, plugs etc .... instead of just dumping it all in at once and hoping it works.

as I said before ... it'* a pretty uncommon motor to be modded... and truley I can understand why... but I really wanna know what this motor can do I think 40hp n/a increase with a 60-75hp nitrous shot ontop should not really be asking too much of this motor... considering what other motors with MUCH weaker internals are capable of holding with proper tuning ... it really isn't too much to ask for... aslong as I'm carefull with my tuning and not just throwing parts at it and praying

Yep, that sounds like a great plan. You certainly have done your research on this. You certainly have some great plans. Although i don't fully understand all of what you have explained, from what I do understand, makes perfect sense.

well I'm not a car/engine newbie... this is my 12th car and all have been modified in some way. I worked in the mech shop of a toyota dealership with no formal certification. when I was in highschool I had a 800 hp nitrous powered small block drag car... in a hair over a week I'll be starting my classes for trade certification in Inboard/outboard Marine and small motor Technician, and I'm in the process of starting a small fabrication company out of my home garage. I'm really not saying this to toot my own horn, just to show that with cars I'm not a newbie... just the Fwd H-body which is why I commonly ask wierd and wonderful questions.

Not doubting your abilities to work on a car, but I doubt the abilities of that engine to hold up to that large change in performance without complete overhaul of every single piece of the engine. However, I would honestly like to see you and your ride at the next Bonneville Fest when you're finished.

I actually kinda plan on 'blowing up' the current engine in my quest for power. not that I'm all sadistic or anything, but it'* got 220+K miles on it currently... I figure I'll fry a piston or pop a headgasket about the time the slightly reworked/rebuilt LG3 is ready to go in. but now that I actually have a garage... and can get engines for $168 and machining close to "cost" and won't be going with the nitrous kit till prolly at are close too the next west coast bonne meet

but.... I should restart the LG3 hi po thread.. and leave this one for fuel pumps

I have no clue what the new GM pumps are. And it may not be possible to find out unless we buy a couple pumps and flow test them.

DrJay'* information on the flow of the Series1 pump comes from a reliable source. We've backed it up, too. His car was built for 350hp. With the 2.2" pulley on it at WOT, and over 100k miles on the stock Delco pump, he'* not going lean. It'* supporting him just fine, and stock injectors, as well.

Project, you really need to locate that pump and maybe even pull it before we can research fuel pump options for you.

Could adjusting the fuel regulator allow more fuel to flow, therefore allowing for a bigger shot of nitrous?
