    Return style wiring HOW TO allowing OE type fuel pump actuation

    If you're trying to use an FC2/3 in an OEM configuration where the ECU controls the pumps you need an extra relay to invert the signal from the FPDM to the FC2/3. The reason is the FPDM controls the pump/relay signal with a constant +12 volts and ground output that it switches. The FC2/3 on the...

    Has anyone ever gone from a 2.9 Whipple to a 2.3?

    No I ran that all of 1 day, maybe 2. I did not care for that restrictor setup. Even so once the bypass was closed you got all the boost. That extra second or so for the bypass to close created a lag I did not like. I love the instantaneous hit of power when you mash the go pedal on a PD...

    Has anyone ever gone from a 2.9 Whipple to a 2.3?

    That's impressive. Mine have never been anywhere near that. I see I posted about half up above, I'm thinking it was less than that. Probably down 5 to 8+ PSI the more I think about it. It's been a while, I really need to dig up old data logs and see. But never 1 PSI, not even close. I just...

    Has anyone ever gone from a 2.9 Whipple to a 2.3?

    Yes I went from a 2.9 Whipple to a 2.3 TVS on the Zinc and absolutely love it and would never go back :) lol I was running a Gen 2 2.9 at 30 PSI. Besides been a royal pain to work on the Whipple with their non removable inlet it just kept destroying lower crank pulleys for me. Every 400 miles...

    Question About Clearances And Fitment

    The crusher inlet rubs on the hood but you can create some clearance. Here's how I did it some time back. Here you can see area marked out to be clearanced and I had started cutting it. The hole cut open I then fiberglassed it in Since I was at it I smoothed out and filled all the other...

    Looking for opinions on piston ring gap

    I did not try different cylinder finishes with the gapless rings. They were seated and sealing very well as are yours. I actually got 0% on my leak down tests which is mind blowing. I'd never seen anything like it. However I don't believe the 2nd set of rings (mostly for oil control) were...

    Looking for opinions on piston ring gap

    I feel your pain. I'm sure it's up in this thread from years ago but Total Seal swore by those rings and had me doing all kinds of work arounds. Oil level in pan, install a vacuum pump on the valve covers to pull a vacuum under the pistons etc. Then they swore it was faulty heads / seals. I...

    Looking for opinions on piston ring gap

    Not at all, it's good someone answered. The thread is what 7 years old lol, valid concern.

    Looking for opinions on piston ring gap

    Yup threw those gapless rings in the trash and never looked back. After all the tear downs, rebuilds and attempts at making them work I'll never touch a set of gapless rings again.

    Cluster inverter reverse engineering project

    Hi Mark, I don't have a blown inverter for you but I've enjoyed the thread. Great work and I look forward to what you figure out and what comes of this. Malcolm

    Sounds like the exact same design sensors I'm running. I have one on each side of the block. It does sound like yours is responding pretty well. I'll PM you and we can compare configurations, perhaps I need to switch sensors again and try the same ones you're using. I have noticed quite a...

    Oh ok. Doesn't the factory sensor have a stud sticking out and requires a boss to turn into? Normally in the valley of the block. According to my notes (assuming I kept updated properly lol) I'm currently running Bosch sensor 0 261 231 188. I too have it work the way you describe but not sure...

    What settings do use on the knock sensors and how have your found their performance? I've played with the knock sensors quite a bit and not at a level where I really trust them. I find way too much "noise" and false positives. I have an aluminum block which I know changes things a little...

    Dipstick Leaking

    I'd just pop it out and replace the o-ring if that's all it is. I went Lokar because of my headers and I had no choice but prior to that stock worked just fine.

    Flow test - are these really 60# injectors?

    Also take note of the pressure at which the injectors are rated and convert accordingly. If brand A rated their 39 lb injectors using 39 PSI and brand B rated their 60 lb injectors at 43 PSI or 50 PSI etc. then you need to do the math to make sure you're comparing apples to apples. Perhaps you...

    I think this is probably what you were looking for lol BTW in that vid right on the hit it looks like I'm not really going, is because my tires are just spinning. I was just laying black lines down the highway going no where lol. It's been too long, 700 ~ 800. Honestly I think it was more...

    Driver's side window not going down

    If the lights dim power is been drawn and the motor is likely bound up by something. I wouldn’t suspect a bad solder joint yet.

    Need a new alternator.

    I think it's a Gates brand but can't remember. Had it a while.

    Need a new alternator.

    Do yourself a favor and get a laser alignment tool. They're about $60 or so but without it you're just pissing in the wind guessing if your pulley lines up or not. Many brands are this way on purpose so you can shim to fit. Remember most of these cars have aftermarket blowers & pulleys...

    Need a new alternator.

    It bolts in but does require a shim or washer to make sure the pulley lines up correctly. Both top and bottom bolt. I used a laser pulley alignment tool and tried various shims/washers till it fit perfect. I also have an aftermarket balancer and lower pulley which adds a little to the mix...

    Need a new alternator.

    My Nations is 14.4 volts (you can adjust to what ever you like) and it holds that solid. Idle, cruising, WOT all the way to redline it's 14.4 volts. Under WOT I may see occasional blips to 14.2. Doesn't matter if cold, warm, cooling fans are on max, headlights etc. Always 14.4 solid.
