You can see this does great up until about 4000rpms on this mild 350. We decided to attack the rolling stock first. This air filter setup which I have in my recommended modifications at the moment for the 4×4 guys proved to be very restrictive and cost us 18hp and 15lbs of torque on the dyno. Multiport should go far to correct this, and I should also mention my heads are a pretty nasty casting with the ports being pretty horribly mismatched to the intake, many of them about 10% blocked due to the poor casting. This will increase the turn in response of the car immeasurably.
This is the route I ended up choosing. On our test car there is an obstruction that does not allow adequate flow in this line and it does not make a suitable return line. A mirror polish in the exhaust port is desirable because it reduces carbon buildup. Also make sure to get several inches of all wiring and all connectors. Exhaust was a little quieter than expected but sounds nice and the performance is night and day difference.
I checked the plug wires 2 or 3 times and I changed the plugs and I even removed the headers and did a compression test on the motor. I physically mounted the two boxes. Thus I ran the stock head for the summer. Use bolts to locate the gasket in place. Like any of the pics in this article, you can click on any of them for a closer look. I had one Blaster coil die on me, an interior connection snapped off.
Dirty refers both to particulates and to the smoothness and therefore the efficiency with which air flows into the motor. Also carries a complete line of chassis components. In either case, look for 16 gauge or thicker smaller numbers are better aluminized piping, minimal bends only two bends are necessary from the cat back on '88-'91 Troopers , and an all-welded muffler with a lifetime guarantee. Make sure to put a mesh up there to keep large objects out of the air box. Back cutting the valves and 3-angle valve job will both help the head flow better especially at low valve lift.
You could also get a new intake system that gets rid of the factory air cleaner assy and restrictive tubing in the fender. We also lowered our truck with a complete front and rear kit from Eibach that worked perfectly along with a set of Edelbrock shocks. Nice try at the pimp though. Because frictional losses increase as the square of the increase of rpm, at 3,000 rpm a real-world everyday rpm you only gain 3. My stock exhaust was leaking in about three places, so I took advantage of that and replaced it with a performance exhaust. The new assembly had an integral fuel pressure regulator plus eight centrally mounted injectors firing into eight nylon hoses with downstream poppet valves leading to each intake port. Both Comp Cams and Crane make truck specific grinds that create torque.
Timothy Pindell I took my Daytona to the Nationals for a few passes. Well, the other day I came across an article on installing a dual tpi set up and I was wondering if anyone here has this set up or knows anyone who does. Many people have had success with simply advancing their cam timing, which can raise gas mileage and power. Trick 2: Free Flow Exhaust Ceramic coating on the headers helps keep heat down under the hood, and keeps the headers looking great Exhaust options really help this little V6. I installed one of pumps from my kit and the fuel pressure went to a constant 28psi which is too high so the adjustable regulator had to be altered showing just how weak that stock pump was. Ken had already done a 3-wire heated 02 conversion which is always recommended on all projects.
The rest can be easily modified later without pulling the engine. I found the stock mounting bolts were a touch too long. Find the right combination of parts and you can build a nice little engine. That is assuming your running around 2000 rpm at 65 or so. Checking the Fuel System for leaks At this point, everything is in place that is needed to fire the engine up.
Same car configuration and tuning, just different dyno, different day. A standard powerplant for S-10 pickups and Blazers, Jeep Cherokees and pickups, as well as Isuzu Troopers, this engine is truly everywhere. These throttle bodies are less than a hundred dollars at a good salvage yard, and the 2. I did set up a MegaSquirt with a single 2 barrel for a 364 a few years back and it went well. Sort of a rear steer solution only it works when you compress enough of the stock soft rubber bushings and flexible rear arm to make a noticeable difference.
It should however maintain the correct idle for the motor. The webpage says these mods will add horsepower, but the guy on the phone says just a little. As for the real output you'll see that only the dyno really knows. The cam is the biggest restriction inside the engine. Every one of the intakes got very dirty downstream from the filter.
