    Re: My v6 Drag Week build

    Rooting for more dropouts is supposed to feel wrong right?

    My waterpump instructions stated that a new seal that is not lapped in can leak. That freaked me out when I put my new one in.

    Re: My v6 Drag Week build

    I was wondering that myself. Both parts should be machined flat...

    I have been wondering if the water pump was cracked when I got it, or if it cracked when I bolted on the engine...

    IIRC you're meant to do 'em in a 2 stage criss cross pattern... coz torquing everything right down in a sequential ring around it tends to do crap like that.

    Though I'll give you evens that if it's a chinese casting it's got a line of bubbles in it where it cracked...

    Referring to the seal & shaft. Warning in my water pump package saying the weep hole might drip until the seal laps in. Mine did not leak.

    Yeah, maybe that is why women say to read the instructions.

    I dont think that line would fly if i bought a pump for my 2.7 where it leaks into the crankcase.. do they just make some better than others, or pre-lap them? Life's mysteries/excuses...

    Re: My v6 Drag Week build

    Finished off a few details on the car last night. Setup TunerStudio on my new laptop pulled the Shadow's tune in. Cranked with the injectors disconnected (to prime the oil pump) then plugged in the injectors and the car fired up right away. Ran it and tweaked the cals some as the engine warmed up and broke in. Once up to temperature, the engine started running smoother (I assume the break-in has started....)

    Tonight I hope to get the tires back on and take the car for a spin.

    Need to put major combustion pressure on the rings to properly seat them. If they don't have enough force to tear down the honing marks, it won't go well. wot pulls and decel are king in breakins.

    Re: My v6 Drag Week build

    Took the car for a test drive/thrashing. Found a variety of issues that I will need to figure out/fix. One of which is that it started getting hot (220F) pretty quick. I know it was 90+F out and I was thrashing on it, but it got hot quick and it wasn't 103F like I saw at Drag Week last year...

    Picked up a fresh thermostat (180F) and clipped the jiggle valve off of it. When I pulled the old one out, found that it was also a 180F thermostat... I am looking at a couple other things.

    1) Going back to a puller radiator fan setup. (probably need a pair of small low-profile fans to clear the header.)
    2) Sealing the area around the radiator fan better.
    3) For summer/racing I may consider just using a restrictor.
    4) Fresh radiator or flushing the system.

    Not sure if I am just not used to driving the car with a manual steering or if the steering is heavier with the addition of the LSD. Pulling out of my drive way it nearly got away from me! This has me considering putting the PS unit back in...

    The 53" belt stretched enough on me that it is loose on the car and was causing the alternator to squeal. Switched to a 52" belt with front bolt of the alternator going through the bracket hole.

    Yah, it will run hotter than you were used to while running in, more friction.

    Well it's like a cam seal, sometimes it weeps a little until it beds in.

    Re: My v6 Drag Week build

    Are you having temp problems when cruising over 30mph or just idling/stop and go? If you are always over 30mph you should not have cooling issues. Those fixes above also won't address your problem. Those fixes above will help with low speed driving. The restrictor seems a bit excessive at this point. Bandaid. Do something like that when everything is top notch. No reason to run hot. I only got halfway on temp when towing another car. Your car should run cooler then your van ever did since it has less weight to pull around and you towed with that van.

    Re: My v6 Drag Week build

    It has been a while since I updated my status. The new engine had a problem with a spun bearing. At the same time I an opportunity crossed my that I couldn't pass up. So gone is the 12v 3.0 and the engine bay now looks like this.


    Yup, that's a 6g74 (3.5L V6) with a T3 turbo header. I still have a LOT of work ahead of me, but this is the new direction. More details to come...
