i have a lt1 that im going to put a 200 shot on with a stock fuel system and im going to add a vortec t-rex inline pump.....has anyone tried this before because i dont want to put an extra cell and pump on my car just yet....or whats the safest shot i can go with on this set up....thanks for the help...and also how much timing will i have to pull out .....i think like 10 degrees will be enough....

 

TTT for ya

 

Unless there is a reason you perfer to stick with the stock pump, get rid of it and put a 340lph intank with upgraded wiring.. The inline pumps are merely a band aid for your problem in my oppinion.. And the timing depends on your motor, 10deg seems a little much...

 

If you're already pulling 126 mph on the motor then you'll have to upgrade the fuel system quite a bit for a 200 shot.

 

I dont want to upgrade my stock fuel pump because im going to go carbed with a new motor this summer.....just wanted to get the most out of it....now im have a th400 and full suspension and the car ran slower times in the 1/8 th last weekend than when i had the m6......i think what im going to do is get some 28 # injectors and turn my fuel pressure up to 60 psi and put the inline pump in for now and see what happens, if it blows up then i know not to ever do that again......then the new motor will be in sooner than planned.....

 

I completely agree with David.If your going to spray that much and want to do it right.David nailed it.
Why blow up a perfectly good motor you could sale to get some of your money back.
