    WTB 25 percent underdrive pulley/ harmonic balancer for 99-00 3.8 Mustang

    WTB 25 percent underdrive pulley/ harmonic balancer for 99-00 3.8 Mustang. This is the externally balanced one with the harmonic balancer. Would preferrably like the belt with it, but will still buy it without.

    '99 Mustang build

    It lives! It fires up!!!! I had finally installed my heads and aftermarket cam myself, and there's no leaks or anything.....it's running smoothly (other than a low vacuum at idle right now). I'd only taken it a few blocks and driven it normally, but I can say right now that it definitely has...

    Here's a couple of pictures of my re-ported lower intake manifold, with a roughened texture to promote more airflow along the boundary layer. It had gained noticeable power, because 3rd gear where it's a 1:1 ratio used to be a slug for me, but it pulls hard in 3rd now. I had re-did my upper last...

    I'd bought a cam, beehive valve springs and hardened pushrods from Dave at Super Coupes Unlimited (he also works with the split port engines). Cam is 218/224 at .555, and should be on the way soon. Today, I'm going to re-port the lower intake manifold, as I'm going to try to grind down the EGR...

    '99 Mustang build

    This photo was a work in progress photo, not of finished ports. In red, I've outlined the high velocity area in the exhaust port. I'm guessing that this is removed by most people (including pro head porters), as it looks like an impediment to flow. It likely is, however, the long side flows very...

    Here's some string/ flow testing pictures, below. The Slurpee cup is definetely MacGuyver, but it's almost the same size as the cylinder bore. Don't laugh! :) Here you can see where the air flows the strongest through both ports, when the string (air wave) is longer--the short side flows a lot...

    I had got a 91 performance tune from MPT Tuning last year, and Ken does a great job with these. He puts the spark all the way to 50 or so degrees of advance at cruise speeds, whereas Bama puts it to about 40 ish (and that's even on their 93 race tune). While the full throttle performance is...

    T-Bird SC 3.8 build

    Some guys might be interested in this, that are doing an M90 build--Magnum Powers is going to make a bunch of 94/95 Thunderbird Super Coupe (square inlet) M90 intake plenums. These are very difficult to find, as they're not made otherwise made new anymore, and the guys that have them generally...

    mustang 3.8 headers?

    Appearance can do wonders--some really nice aftermarket rims and tires can make the car look infinitely better. In terms of engine, how many thousands of dollars do you have? :) Because it will take a lot of money for some serious performance. The best bang for buck is always gears/ rear...

    Damn, now that's a sexy car!

    T-Bird SC 3.8 build

    I'm mostly done porting/ texturing the heads, and am working on some lower intake manifold port designs that should improve velocity. The lower intake manifold isn't the most optimal design, but it had to be designed that way to be crammed into the engine bay. I'd vacuum/ thread tested it, and...

    I'm still waiting to get my heads back (machinist is still backed up), but before I had dropped them off, I had read this: http://hotrodenginetech.com/pipemax-creator-larry-meaux-on-race-engine-head-porting/ I had originally polished the surfaces, but then I had decided to roughen up all the...

    '99 Mustang build

    Update: I had dropped my heads off with a local machinist who came recommended to me. They may take until early-mid February, as he's backed up, getting married, and wants to be able to flow test each port on the same day, as he finds that as temperatures change, the results do as well. So we'll...

    I'm not really the one to ask.....I'm not a suspension expert. :)

    '99 Mustang build

    I'm taking the heads in to be milled/ pressure checked/ seats checked and flow tested tomorrow! Very excited, but also a bit nervous, because this is where some real official data starts happening. And of course, my heads last year that I had done, there were some errors on them, so the real R&D...
