    Yeah, stock slider cam. It will be getting a Bo-Port 1.1 cam soon....along with some other "work".....

    I'm pretty happy with the numbers above given the limited mods so far.

    Ok, here's an update. I put the car on the dyno this morning and I'm running outta fuel (leaning out). The max numbers before leaning out where:

    Max HP: 182.1 @ 4350
    Max Tq: 229.6 @ 4150

    The car started leaning out around 4350 RPM. My set-up is as follows:

    Bo-Port head with Stage III porting and 1.1 Cam advanced 5 deg
    35lbs injectors
    PE Computer
    T3 stock (rebuilt - I don't know the A/R)
    Rod's Header, 3" exhaust, no cat
    190lph fuel pump

    We're thinking the head is flowing too much air compared to fuel (maxing out the 35lbs-ers). There's more power here, but I have to figure out how to get it safely without stressing the motor. Does anyone know the max injector size we can use on the stock computer?

    You should have a real torque monster on your hands here. I have seen the stock injectors go up to 300Hp. That is pushing it though and without a wideband for monitoring, it is easy to go wrong. With that head and the work you have done you should be around the 260-275 range. The PE has an aggressive spark curve, watch out for detonation. Use some octane booster to be safe. I have seen some people use the 42s with the stock computer, but it still requires tuning, you are leaving lots of horses on the table with out it. Now for some questions, was the knock sensor plugged in? What did you use for boost control? What boost are you running?

    Raven - knock sensor was plugged in on all the runs. I'm using an adjustable boost valve (Hallman Boost Controller - Pro model) and we didn't go over 16lbs of boost. Oh...and I'm using a slight ported in-line intake.....I like the idea of the equal length runners as I'm after torque more then HP.

    When you installed the fuel pump did you eleminate the resistor in the ground wiring?

    I didn't install the fuel pump....it was in the car when I got it. However, I know the previous owner(s) and they know what they're doin....unlike me on some days.

    Fuel pressure was good throughout the runs (I've got a gauge hooked-up) and pressure built about 1lbs per 1lbs of boost. I don't think its a fuel pump or regulator issue.

    Are you still running the stock alternator?

    That's good but consider this, a 190 pump appears to need up wards of 20 amps and this is supplied through the EEC. It spikes even higher and you are supplying it across 25 year old wiring. It places a high demand on the available power and shares it with the injectors and a host of other items. Run a fused 10 or 12 Gage wire from the battery to the relay under the seat and displace the wire from the EEC that supplies power to the fuel pump at the relay. It will free up power to the injectors and possibly eliminate some noise from the fuel pump to the EEC. The injectors will be better able to cope with the demands of your engine. It will help with tuning.
