    Engine holds on to RPMS when revved

    Im glad Im not the only one that feels that way BlackStang03. Dunno, and that's what I am hoping to get answers for here. :D I would love to have that quick throttle blip and roar. If I figure it out with the mods/bolt ons in the near future I'll let you know, I was just hoping...

    Is there visually a way to quickly distinguish between non PI and PI 2V's? Thanks!

    Engine holds on to RPMS when revved

    Yah that's absolutely my point PhatCAt. I see plenty of vids on you tube of quick revs on 01-04 GTs and am hoping that with mods and a little tuning mine will open up like that. Just not as satisfying. :(

    Problems Suck, But the power i like

    Yes Ford sprays the butterflies in their TBs with a coating to help it resist build up of gunk over time. You would be just fine cleaning it with a nonabrasive, mild cleaner, but nothing that would risk stripping the coating. I port and polish 05 and up TBs for S197's and the first one I did I...

    S197 wheels and tires

    I ran 305's on the back of my 06 GT and never had a problem with em and I had the Eibach prokit springs that gave the car 1.5" drop. I think I had 255's or so up front, but I have friends who have had as fat as 275's in front on s197's without them rubbing with lowering springs. Bear in mind...

    Engine holds on to RPMS when revved

    Yah........i just want em all to be fast as hell and sound as mean as anything out there when ya rev em. I don't see the problem with that.:D You are absolutely right....it doesn't make it any slower......and it moves a lot better with the 01 PI motor than it did with the stock 98 2V...

    Engine holds on to RPMS when revved

    Yah UDPs are in the very near future and I am planning to upgrade the throttle body to 75mm version next week too. I am hoping as the mods increase this annoyance goes away. Just looking for a magic bullet of sorts to fix it ASAP. Thanks

    Engine holds on to RPMS when revved

    It idles beautifully. The other motor did too. It just bothers the heck out of me that it returns to idle from a rev so slowly. I mean REALLY bothers me. My GT500 revs smooth, sounds mean as hell, then quickly returns to idle. My 98 with 01 PI motor revs smooth, sounds good, and...

    Engine holds on to RPMS when revved

    So I have a 98 GT vert with an AOD trans. I did a 2001 PI motor swap this week. Problem is when I rev the motor the RPMs SLOWLY return to idle. Not a nice crisp rev and return to idle. It revs quickly enough, just takes a few seconds to slowly drop back to idle. I think its a tuning or...

    Preferred Underdrive Pullies?

    Summit pullies are Trick Flow pullies, just repackaged. They are good pullies. Plenty of people have used the Summit/Trick Flow brand for many miles with no problems.

    Exhaust Question

    LM1s are simply muffler delete systems. I have a set on my 09 GT500 and they are straight pipe with a "resonator" tip on them. There is no resonator really just tips. :rlaugh: IMO if you want to hear what your 03 GT would sound like with LM1s.....take out the mufflers and put in a length of...

    what are cheap 99-04 mustang gt mods or upgrade kits?

    Gears........as mentioned above, most of those mods will produce very little HP when performed individually and deliver almost no noticeable SOTP feel. I put 4.10 gears in my 1998 GT with 2001 PI motor swap and it was a huge difference. I gained no HP at all from the swap (probably lost a...

    Anyway have a picture of the dog-bone?

    I am going to remove my dogbone as well, but i had NO idea about the fender well weight on passenger side! Is this on all the verts? Would my 98 have one and where is it located? I would love to drop 25 lbs that fast and easy. :D Thanks for the help.

    What are the best tires I can get???

    If cost and treadwear are of no concern to you and your ride isn't going to be daily driven then go with the NT05Rs. I have a set of those on my 600+ rwhp 09 GT500 with 3.73's and they hook better than anything I've tried so far. Just get the biggest contact patch you can given your tire size...

    SCT results (before and after)

    I have SCT tuners for both my 98 GT and my 09 GT500. The HP/Torque gains on the GT500 were HUGE with just CAI and tune (50-60hp), but with N/A 98 GT the hp gains were minimal at best. The most noticeable difference in 98 GT is the frimness of shifts with automatic transmission. This made a...

    Engine Swap dilemma

    I have a 98 GT vert for my daily driver and it's time to turn up the performance of it. I have 137k miles so I am thinking I would like to have the block refreshed and machined soon anyway. I have considered a PI swap with some port work and cam swap, but I can get my hands on a 2000 PI V8...
