I gotta get more speed out of this heavy car/truck/van(?), 3500 lb.s with 3/4 tank & me. It has run a best of 14.6@97 and I want at least low 13's. Present mods are: plastic manifold, air box mods with K&N, hardpipes, and suspension.
Anyway; thinking of SST plus intimidator manifold, 3" turbo back, 55 mm TB. How high could I boost without fuel mods, or would I need FPR mod or return fuel line? I would like to tune with SCT, seems a logical way to go if I can get hooked up with a vendor doing this. And what about cams, crane 16's; good or bad idea-anybody running these? Maybe meth inj as well since we have to run a small stock i/c. Give me your thots
You've got some good starter mods, but there's still lots more to go until you can shave over 1 1/2 seconds off your ride. Your 97mph trap speed should be good for a 14.2-14.3 so it sounds like your suspension is right, but you're losing a couple tenths off the line. My guess would be a 2.0 60 foot time if I had to guess. I wouldn't worry about cams/gears just yet, plenty of stuff can be done before then. I really couldn't tell you how much boost you could run on stock injectors with the SST turbo, I skipped playing with the stocker and just went 57 trim on my PT. First things first, grab up a wideband if you're going to be playing with fuel and boost. Secondly, stage 2 injectors and a walbro fuel pump should be able to handle what that SST can throw at it. I don't think you are in the returnline territory with that particular turbo. Do NOT put a fuel mod in your car unless you feel like replacing the pump every 20k or so. The added stress on the pump wears it out at a much quicker rate than stock psi. Have fun with the SCT...some people like it, some don't. I don't feel it's completely necessary just yet, I'm doing just fine controlling mine with a returnline and an safc. Meth injection is a very good idea, without changing anything I made to passes on the dyno, one with meth off and one with meth on. I did meth off just to make sure the engine was nice and warm for my comparrison. My results...I picked up 24whp and 36ft.lbs of torque with just a flip of a switch...no tuning no nothing, just turned the meth on. I run 100% meth on my car, it didn't seem to like anything else and it really came alive once I put 100% in there.

Just do a lot of research on mods you want to use. Turbo efficiency, fuel mods, fuel controllers, ect ect ect. I was running at 30deg of advance at 15psi of boost,,, NOT GOOD,, got it under control with the SCT tuner,, now much safer. My car ran a 12.12 @ 115 at 21psi of boost,, untuned. Will get the car dialed in this spring.

Yes, I do like what I'm hearing about meth injection; but you're the first that I've heard about danger of fuel mods, as most srt4 are doing them- I thot our pumps don't run at the proper voltage from the factory?
Wideband will go in with the new exhaust. I guess biggest question will be do I have to stay at stock boost without piggyback or fuel mods, or how high can boost go safely.
Presently I'm getting 2.2's 60 foots , which I don't feel is too bad with stock 205 goodyear RSA's. I am going to 225's as soon as I can find some new rims I like.
actually you don't run out of fuel by spiking 18 but you might as well if you don't have a clamp or afc to hide the boost with, because either way you're going to hit a brick wall when timing gets pulled. I've spiked as high as 20-21 on a bone stock fuel system without problems. It's not where you spike that matters, it's where you hold
Been trying to read up on a lot of stuff, and it looks like with an upgraded turbo(even SST), that more fuel will be needed for anything more than stock boost. So now I'm wondering if a rewire will be enuf or a pump maybe needed as well; but I don't want to go overboard on fuel or I will need a piggyback to pull some out. Whew, so much to learn.
On my 5 speed I am running a Keeny Bell Boost-a-pump with a stock turbo to keep enough fuel in it under 23 pounds of boost. You should spend a little to get some dyno numbers and air/fuel ratios before you go any further. My auto runs pig rich but my 5 speed ran lean. I got lucky in doing a dyno tune before running it real hard.
You're just jealous cuz I have water injection and you don't jeff! Just playin with ya buddy...musta been really bored over there if you're over here already lol

I told ya I was...
Besides, there are no trolls hangin out here that are after me.
I just need to cotnact AMX to get a 45 degree connector pipe and cut the upper charge pipe so the VAK2 will clear the tranmission. Then drill and install a water injection nozzle. Sleeping Beauty will then be even more of a sleeper.

We can build you one of those for the price it would cost to have a FREE pipe shipped out here...plenty of options. Lol, you oughta see what I'm working on right now with my fuel returnline...if I can pull this off, I'm pretty sure I can make a pipe fit the 5 speed

I have the VAK2 and one cut, hose connector and water injection kit results in me being done....for now....
