105mph in all motor GT, HOW?

I want to go 105 baby all motor. What do I need to do next? I ran 13.8 @ 100 last week in the sun. I want to be able to keep with LS1's over 70 mph.

Heads, cams, ??? what now.

If your Auto I dont see it . 5spd however, I recommend the Following 4.10's, 80mm C&L meter, full drag suspension, and lose as much weight as possible:Go with Welds((Skinny's up front))and any insulation you can go with out, , shed the tire and jack, remove the rear wing, Aluminum Driveshaft,Battery in the trunk, and you could go 105ish @12.80-90 or so

He'll need another 50-70 rwhp at least. A 75 shot of nitrous should get you close.

On ET's I might add, he would not need a 75 shot to do that, I see a few N/A 4.6's running high 12's at like 103-105 range.

If he does nothing else but add power he'll need the juice. Adding that kind of power without an adder on a 2v can be a real trick. Now if he thinks he can start knocking down 1.60 sixties he can do it with less power. He'll also have to work on weight and aerodynamics. But nothing's impossible. It's just easier with juice.

Actually, if he really wants to run with LS1s over 70 a centrifugal blower is the only way to go.

I'm running 103 mph on street-tires, mods in the sig. Some more parts and tuning and I think 105 is a possibility. I can already hang with many LS1's over 70. Notice I said many not all

I have ran a [email protected] in horrible weather and a 2.2 60ft. This was on street tires with only gears, exhaust and pulleys. I'm going back to the track soon and will let you know what happens.

My friend is already running 105mph WITH AN AUTO. He has C&L meter, street tires, 3500 stall, exhaust, throttle body, and pullies. He is going to get the Steeda T/A. It is a '99 believe it or not and he ran a 13.4x at Baytown @105mph. It has 4.10 gears also.

You guys talking about BEST trap speeds are fooling yourselves. Find out what your AVERAGE trap speeds are. Then you'll be close to what the car is really making and where it will be consistent. Also weight is everything in the calculations, make sure it's accurate.

I have run traps speeds 30-50 hp over what my car is really making. But my average traps puts it right on what the dyno says. Weather and track conditions change, do let those things fool you into thinking your doing better than you really are.

You want to run with LS1's over 70 your going to simply need more power. Probably somewhere around 300 rwhp to start with simply because that's where most of them start at. Remember, not only are you at a HP disadvantage but a torque and aerodynamic disadvantage well.

Also changing the converter will raise traps some, but they won't do much for you when that LS1 gets over 70.

Again add a blower and gears then look past the LS1s to other modified stangs!

I went 104.74 mph on 18 inch street tires with the car at the bottom of my sig. The other mods it had were 4.10s and a chip. I only went once made seven runs and every full pass was 103 to 104 mph. This was a full weight car with saleen ground effects and lowered.

I trap right below 105, and still cant hang with ls1's. My best freinds 2000 SS with exhuast, bolt ons, and gears, traps around 116mph with stock heads and cams and runs 11.80's. You will need a power adder to hang with ls1's on the top end, period. You can hang with them on the street from a stop or at the track with superior traction and gearing, but up top, they will walk you if you are NA. I know that Raven, Novified, and a couple other cars here trap over 105, but many ls1's trap that stock and well over 110 with just simple mods. And after 100, those things keep pulling hard, I mean real hard.

Doug (vrtical) on here just trapped 104.39 MPH in his '99 GT. Cleaned up Bullitt intake, 3.73's, Nitto DR's, offroad pipe, catback, and maybe a couple other bolt-on's. I don't see why this combo, with longtubes couldn't get you over 105 MPH... throw in some reground cams, and you're there for sure.

Or, ask Bill (Mustang92). He's trapped over 105 MPH. Usual stuff as well, with ET streets, or slicks.

Joe (RavenGT) will more than likely clear the 105 MPH mark plus more very, very soon, ask him too! I can't tell ya........ JUST YET!!!

:evil Hes got a vert, think weight is gonna be an issue. I also have pretty much all the bolt ons except for LTH's. I had 13 runs on Saturday and my average mph was in the high 103.xx range. The car will be averaging 105 or better very soon.
