    Thanks Tu, and thank you for your business!

    I am also working with Jay on his 71 Camaro tune.

    I hope everyone has a great weekend and please don't hesitate to be in touch for your tuning needs.

    Andrew,

    I'm considering a Mopar project and can't bring myself to swap in a LS so If I decide to build the car I'd go with a 360 stroked to 408. I want to go with some type of fuel injection system. What would you recommend? Not going to be a big cammed motor. Just good heads and lots of torque.

    For a throttle body style injection, that retains the look of a carb, I like the new Holley Terminator X Stealth systems. They use the Terminator X (or X Max) ECUs and have a throttle body that most people will think is a Holley carburetor. I like these better than the Sniper systems because these mount the ECU outside of the engine compartment. I am pretty sure that Holley makes a Sniper distributor for a 360 and I would run that with the Sniper HyperSpark ignition box.

    https://www.holley.com/products/fuel..._stealth_4150/

    I would also strongly consider installing a under hood power distribution center, which can be integrated with the Holley EFI. It will provide power for the ignition system, fuel pump, and cooling fan(s). The Terminator ECU will also support PWM fan control (there are various solutions for this) and I would encourage doing that.

    I would combine this with a VaporWorx fuel system, using the 5th gen Camaro SS pump, which will have enough flow. With this system you don't need a fancy gas tank, any external regulator, or an inline filter. Carl makes a simple modification to these pump modules that makes them run at a constant 60psi. This system is installed in Ty's Firebird and it works awesome.

    Andrew thanks for the reply.
    I've done a number of LS swaps over the years using mostly GM components so FI doesn't scare me. I would use all Holley parts so the system is "integrated". When I did a LS swap I purchased the ecm and harness from one company so if there was a problem I had one company to talk to if there was problem.
    I would completely rewire the car so a clean 12 volt source wouldn't be a problem. I hate old crappy old wiring.
    What is the advantage of the PWM fan control? On my LS swaps the ecm turns on the fan (typically a 16" Spal with the biggest radiator I can fit) at 215 degrees on and off at 195 degrees.
    The car I'm considering is a 74 Dart. Had one in high school. I don't know if the tank has a big enough flat spot for the VaporWorx fuel pump but in lieu of that I would go with a Tanks Inc tank with a 255 pump and C5 FPR.
    Again I haven't bought the car yet just trying to gather info.
    Thanks again for your reply and info,
    Jim

    PWM = Pulse Width Modulation. Basically it very rapidly pulses the power on/off in a way that allows the fan motor to obtain full voltage and cause no damage, but by varying the "pulse width" or how long the pulses last you can vary the speed of the fans. This is standard in all new cars including for fuel pumps. It is also known to extend the life of electric motors because they aren't constantly running full tilt. The real advantage is that instead of your engine getting up to 215 and the fan running like crazy until it gets down to 195, the fan would come on slow at 200 and slowly increase in speed as the temp continues to climb and be full power at like 210. Then you could even slowly ramp the speed down as the temp decreases. This is good for your engine too because it keeps a more consistent operating temperature.



    Hope that helps. I'm a huge fan of this technology. I use it for my fuel pump to extend pump life and reduce the amount of heat absorbed by the fuel. This is why Andrew recommends the Vaporworx 5th gen fuel system along with it now making the fuel system returnless.

    E85

    Have you ever tuned a system for E85?

    Yes with LSA blower. I tend to be fairly conservative. I focus on drivability more than extracting the last bit of power.

    Sounds like you need a driveway dyno!

    Thanks for sharing your knowledge. I have an LS3 in a 68 Camaro, Holley 4150 throttle body, Holley HP ECU. The IAC flares / ramps up on start up, with revs rising to 1700 rpm for about five seconds immediately upon start up, then drops back down to idle at about 1000 rpm. Could you offer any advice on how to lower the IAC start up ramping rpm please?

    There is a parameter in the idle ICF that can be adjusted to fix this. Also your IAC park might be too high.

    Is there a part number on that IAC? We make those for Holley too.

    I'm late to the party here but, Andrew has helped me and my LS3 Terminator swap in my '78 TA. The LS3 is a GM crate motor rated to produce 533hp, last weekend I had a chance to dyno the car on a Dynojet and it pulled 410RWHP! With Andrew's help the driveability has been improved greatly and it's street manners are very good. Andrew is very responsive to my questions and he even provided assistance to a clutch issue I was having- nothing to do with the EFI system. It's been great working with Andrew!

    I'll have to look up the number, but generally, on the 4150 style TBs Holley uses the Chrysler style IAC.

    I could probably ID it with a picture. The only market coverage we don't have is the BMW IAC. As you might guess, it's an overbuilt beast of an assembly.

    Nicely done! I can't wait to get mine on a dyno once it's all back together.

    Even better than the number from the dyno is the feeling I get when I press the pedal on track! A mix of terrified and happiness!!!!
