TopCat501 Posted March 29, 2009 Report Share Posted March 29, 2009 Just saw where the PSI Motorsports GT500 broke 200mph 3 times today :happy feet: 1st run @ 201 2nd run @ 202 3rd run @ 205 I'm not sure what mods are on the car. I think relatively stock GT500s run in the 170s. They'll have a chance to go faster tomorrow Man that must be a blast to mash the pedal to the floor for an entire mile :bandance: and it's legal Link to comment Share on other sites More sharing options...

blkGT500nCA Posted March 29, 2009 Report Share Posted March 29, 2009 Is there anywhere else besides texas that they do this?? On concrete. Has anyone gone to the salt flats in Utah??? Link to comment Share on other sites More sharing options...
ingram4868 Posted March 29, 2009 Report Share Posted March 29, 2009 I won't even drive mine in the rain. The idea of driving on an open road made of salt would give me nightmares of endless cleaning. I wonder if the salt would clean some of the rust off the steel parts under the car? Link to comment Share on other sites More sharing options...

mrdci Posted March 29, 2009 Report Share Posted March 29, 2009 And A Toyota Supra 246.2 mph off the trailer street car, second run motor let loose. I'd like to see what the car looks like cause at that speed I'd think the hood would be ripped off. They have to have some different aero package than the stock one.

Curt A Posted March 29, 2009 Report Share Posted March 29, 2009 The Supra stock, has two front hood latches. The body is stock except for the TRD rear adjustable wing. Link to comment Share on other sites More sharing options...

Tob Posted April 1, 2009 Report Share Posted April 1, 2009 Fordie, did any of these GT500 guys comment on the logic (tune) they were using to alter/defeat/eliminate the speed limiter? In addition, were they using numerically lower gear ratios? Tob Link to comment Share on other sites More sharing options...

He performed the work on my Shelby I wonder if it will go 200+ http://www.modularfords.com/forums/showthread.php?t=131983 Link to comment Share on other sites More sharing options...
skiph Posted April 3, 2009 Report Share Posted April 3, 2009 My only mod is the CAI and tune. But the tune came with some details of what it did. a) up'ed the rev limiter 0.2k B) eliminated the speed limiter and some other goodies Might have to see if I can pay a few $$ and run it on a track somewhere around Atlanta to see what it will do. Not sure where to start to find one that will let me use the track for a few hours for some $$ That is STICKY asphalt too. Not the slick stuff on the roads, so could be interesting. Oh, and salt does not clean rust off of ANYTHING. It promotes rust. No salt flats for me. Nada. Link to comment Share on other sites More sharing options...

You can modify or eliminate the speed limiter with a Tune, in my case I had a SCT X3 handheld and VMP custom tune, you can set the speed limiter as desired. We ran 165.9mph with no other power mods. Eddie Garza had a stock GT500 with _no_ tune and ran all day at 158mph against the limiter (but lots of fun anyway). So the short answer is call Justin at VMP, for ~$440 he can defeat the limiter and add 50+RWHP. Cheers, Fordie. Link to comment Share on other sites More sharing options...

On bikes we have to safety wire everything etc., anything special for streetcars? Link to comment Share on other sites More sharing options...
