Thatr depends how far you want to push the boost up. I would suggest without any upgrades or monitors (wide band o2 and knock sensor reading) I wouldn't suggest exceeding the factory cut-out of 14 psi.
i was only thinking about 12lb lol this is my dd so i am keeping it safe

will my fuel injectors and my fuel pump support 12 lbs with no problem?
The factory pump and injectors *should* be able to supply the fuel you need to run 12 psi boost. I only say should because if your pump is weak and old, or your injectors are plugged then you may starve your engine of fuel.
The only sure way to know is to run with a wide band o2 and varify you are richer than 12.0 a/f ratio
An acceptable way to know is to use a narrow band o2 meter and ensure you're running "full rich" on that gague.
the car only has 64,000 original miles on it so i am pretty sure it will be able to is 12 lbs a considerable power increase over facotry
I'm sure you'll notice it! It has been said that our cars produce an additional 8hp per pound of boost added.
nice i cant wait to see what it can do
The car runs 11 then over time degrades to 7 stock so 12 would be doable IMO without needing to worry about fuel. Chrysler was known for putting extra in from the factory anyway.
oh ok thanks for all the advice kinda new to td's
You should just get an MP computer and not mess with the g-valve

why do u say that dodgez
G valves are fine, and cheaper than a MP computer.Originally Posted by DodgeZ
How many years?..oh.
thats actually what i was going for most bang for the buck and everyone i have talk to said g valve they help build boost faster and they are safe to run twelve pounds with no intercooler on a stock 86
Bang for the buck, you're on the right track. Be sure to use the highest octane available from here on, please.
The Mopar Performance computer is a nice upgrade as well. As would be a blow through set up with a good intercooler. Baby steps.
is it safe to run 87 or 89 with 12 lbs because 93 here is like 3.00 a gallon
Yeah I'd recommend that too but I'm biased because I have one sitting on the shelf that's about to go up for sale.
if you only have 64k on the car (not 164k from rolling over) then putting a gvalve on it going to hack up what I am guessing is a nice car. With the computer you should be getting better timing curves and adjusted fueling.
So? I think the day of g valves is going to be fading away soon.
If you are cheap then you may want to look at some other cars to mod. Your car is 25 years old. If you want to get performance out of it you are going to be looking at doing some freshening up of the motor. If you can't afford to do it the right way or can't pay to put the right gas in it the odds are you won't want to spring for a headgasket or rebuild the short block when the rods bearings go south. I am not trying to be mean but people fail to remember how old these cars are.

actually, dodgez i already have a fresh t2 on a stand i just don't want to swap it in the winter lol and as far as the fuel question i was just curious oh and dodgez u weren't coming off as rude just truthful and i appreciate it, moparman wish i had one on the shelf

here are some images of my car
my experience, with a 255HP walbro, stock injectors, and a 3bar cal, 20 psi at 11.4 afr is possible.
No idea how far past recommended duty cycle that was.
That was on a stock 89 2.5 motor with re-used 005 HG and re-used tty bolts! Still runs too....
I wouldn't go over 10 with no ic though...
12 PSI popped the HG on my NY... stock 86 log. The knock sensor wasn't working, and I kept adding timing while watching my scanner. I would go for it, but set you base timing at 10 degree's and the MBC at 12 psi. I would also run some good injectors cleaner through it before I attempted it also.
