... true duals with 2 cats and 2 flowmasters (1 each on each side obviously) Cold air intake Adjust timing to 11-12* MSD 5 box MSD ignition coil Maybe Edelbrock intake Any other things to look at? Not able to spend a lot of money right now (broke college kid spending too much on beer) so I'm ...

I am having a problem, I hope maybe someone can point me in a direction. My 1986 GT has been sitting for about three months waiting on a heater core replacement. I had the dash and heater box out, of course. I unbolted the throttle cable ...

I'm new here, but I thought maybe I'd post a question about something I'm working on. I built a hot hod with a 5.0 and SD from an '87 ford van a few years ago. I didn't like the looks of the upper intake even though I ran it like that ...

... the basic kit its the new 2.1 with 5-6 psi..I want to keep my stock injectors and MAF but im going to run a larger fuel pump a 190 lph or maybe even the 255 lph...I heard its a little tricky to tune this as far as it makes boost really quick so you can ping i was told to back the timing ...

I dont have any pics sorry,I'm not too good with the computer maybe I can get sum on here soon.I can tell you what i've done to the car as far as modifications.It has the stock block 302 but has been bored 0.30 ...

... 150 adj. The moter had close to 200,000 miles on it when i made that pass.i am now rebuilding it with a 0.30 over bore and new forged pistons and maybe a couple other new parts and tricks. my question is about my nitrous setup. I use a micro switch and spray the car the full 8th mile with the ...

... alternator installed, which I did last night. After work today I took it out for a test run on some of the county roads for about an hour or so, maybe 45 miles at most. It runs STRONG, although there is an occasional slight stumble at around 2600rpm now & again. During this drive the Jeep ...

... be. I have a 6 month old hi-flo water pump w/ UD pulley, 160* thermostat, and stock radiator. I just replaced the thermostat today thinking that maybe the one I had put in when i replaced the water pump quit working but that doesn't seem to have fixed anything. I can't imagine the FRPP water ...

... as I had hoped when I had the shocks and springs installed, I'm not sure why. I know the ford racing springs are stock rates, just a lower height, maybe that's why. Anyway to my question. Will some aftermarket front and rear sway bars help? If so what are some experiences people have with certain ...

... have done. The 3 gauge pillar cover was one from LRS. It seems to be of good quality. Now I did use the old cover underneath the new one and maybe that was my mistake but it actually seemed to fit better with the old cover under the new one. Anyways, any input would be appriciated. Thanks

I think you should be ok once you do a little tuning.
I, personally, have run 24# on SD without an issue. 30# should be doable with an AFPR and maybe an IAB adjustment or two. I definately don't think I would go above 30# on the stock SD electronics (ie get a DFI setup or chip)

I've been wanting to get a nicer fox body copcar anyway, so maybe now is as good a time as any to sell it, now that it's warming up. Didn't know about the orifice in the heater core. Thanks for the input.

... the stock cooling system shouldn't be putting out much more than ~17 psi. You may want to check your rad cap if your pressure is high... maybe it is old or for the incorrect pressure range and thus not releasing... making your heater core function as your rad cap should be...ouch

... an ambient temperature of about 66*F (ie cold start) I would expect to see ~3.5V. At an operating temp of about 180*F I Would expect to see ~1V maybe even less than 1V. Also is your car throwing any codes? As for leaving it unplugged I would not. This is part of the input for the fuel and ...
