2.2L vs 5.0L question

[speeduphoria]

Tell you what my 90 3.0 Auto Spirit gutted would keep up with a 90 auto 5.0 vert. The verts are heavier, and there are optional rear end gears available but I would think you would have no problem at all beating it, especially if it came with the 2.73 gears. I think your dad just wants to believe the 5.0L is a muscle car when its not, specially auto. A budy I had spent alot on modding his 87 GT 5 speed(13.8 1/4 mile) and my other buddy's 92 Daytona R/T(13.5 1/4 mile) would whip it at the track and highway with similar mods.

May depend on distances too, how far you're going....
I had a nice built TI engine in my '87 I owned back in the day and actually beat two of my buddies that had auto 5.0's. They're tanks. Make sure you're light, spool the turbo enough from the line to have boost on go, but not too much to spin. You'll beat him, just don't be cocky. Graciousness is more enjoyable

[turbokid]

ya if you can get an easy launch and hook up then hit boost you should be fine since you are newer to stick cars. IF you try to let the clutch out and and floor it l(ike my buddy does who has an srt4 and is used to his SHO taurus and got beat by a stock STI by spinning his tires and missing third gear) then your gonna get a hurtin.

Its probably around a high 14's to 15.0 car stock. An LX is faster than a GT. GT's are heavier and Im pretty sure they had 2.73 gears, I think auto LX's had 3.27s and 3.55s in 5speeds. Dont quote me on it though, I have seen plenty of 2.73 mustang rears.

AFAIk the 2.73 is standard in the autos and 3.27 was an option, but again I dont know much. My buddy did a bolt on build on his LX auto(had 2.73 gears) and it was still a turd off the line

[InfinityShelbyZ]

Well, regardless....(hope I don't offend anyone w/ this factoid) if he's like all of these other morons w/ 5.0s, then he's arrogant, thinks his car is the best, and he doesn't know a thing about racing it. If any of that's the case then smoke him one for us.

ha ha a stock 2.2 will beat a 5.0. i say you'd win bye 2 car lengths. are you going from a digg or a roll?

[venom800tt]

80s Mustangs are crap, i used to have 87 lx (my first stick shift) thank god i learned manual with that not my Daytona. They're heavy and junk but mine was 2.3l not 5.0 Im pretty sure you can beat him easily just make sure you shift it on time. Do you have a exhaust mod? thats very important stock exhaust is restricted and your making boost for nothing. I got 2.5" because i got Mitsu right now but you shouldn't have any problem with 3".

[ATaylorRacing]

The 1989 5.0 Mustangs had 225-235 hp and weighed in at 3350 lbs.
Here are some 0-60 times and 1/4 mile time from various new Fords
of around that time:
85 GT / 6.4 / 14.9 (C & D Jan 85)
87 GT / 6.4 / 14.4 (Automobile Apr 87)
88 GT / 6,4 / 15.0 (MT Jan 88)
89 GT / 6.2 / 14.8 (MT Jan 89)
90 LX / 6.4 / 14.9
91 GT / 7.3 / 15.6
92 LX / 6.2 / 14.8
93 Cobra / 5.9 / 14.5
93 GT 8.0 / 16.1

I used to beat 4.9's (that's right, 4.9's) all the time in my '89 Daytona Shelby. That's all they had at my high school 10 years ago. They always sounded so mean but only the modded ones actually moved. Just remember your shift points and keep a quarter tank when it's time to run. Keep the boost level constant. In the end, it's all about driver ability and I would venture to guess that most Mustang owners expected the car to just GO without being able to handle the machine.

Let us know how it goes, but I would even up to the line with confidence against a stock Mustang.

Edit: Racing is all about knowing your "enemy" and which challenges to take and which to walk away from. This is one you take.

Key point...no one thinks about or they just forget to mention. Very important!

I used to think that having a low amount of fuel in the car would make a huge difference in the way it performed, but if you have enough power this simply isn't the case(for our cars anyways). And yes, even stock out cars have enough power. Think about it, gasoline comes in around 6# per gallon. Multiply that by 14 and it's only 84#'s. The basic 1/4 mile calculator says this isn't even worth 1/10th of a second! That's accounting for the ENTIRE tank of fuel! A true 1/4 tank of fuel will come in around 21#'s. The difference between that and a full tank is 63#'s. That's the equivalent to a small child(not condoning racing with small children in the car). Unless you are seriously lacking in the power department, then I wouldn't be concerned about the fuel level issue. The other thing to consider is that running low amounts of fuel increases the chances of running lean due to fuel starvation at the pump. I agree there is he little cup the thing sits in ect., but it CAN happen.

The saying it all adds up is true, but unless you are going all out, I just don't see the point in worrying about that. Now, if you've taken the rear seats out, the spare out, the passenger's seat out, ect...THEN I coul see worrying about the weight of the fuel...

[InfinityShelbyZ]

Tiny little amounts can be the difference b/n a winner and loser. Heres a little lesson in common sense. You're completely ignoring physics (although small) there is still a weight transfer.
Yea, I know this is mostly only for the RWD guys, but our @$$ ends of the cars are still dipping on launch. That transfer of weight pulls off from the front end where you need your traction. The more weight you have in the rear, the less traction you have up front. So Reaper does say it may change slightly, hes downplaying it. If you ran 2 identical cars one w/ a full tank and the other w/ a 1/4, the 1/4tank is obviously going to win by more than he's playing it out to be simply off 50-60#s.
If fuel amounts and placement of fuel cells were as important as he states, then motorsports wouldn't take so much time deciding the size of a fuel cell and the location(Even being on the right or left side of the car plays a factor).
Yes, I know this isn't some big race situation that most of my ramblings will matter in, but every little bit counts. Shave off some weight here and there, add a little bit more traction, 2-3HP here and there really add up in the end.
Its not like its a HUGE chore to run the tank a little lower before you race. And in response...again to my pal Reaper .....a 1/4 tank in these cars is what? 3-4gallons. The odds of you leaning out on a 1/4 run or whatever they do is pretty much nonexisitent, and theoretically even if he were to lean out for some short distance the damage done wouldn't even be notable. I do agree, if you do this you may as well pop the rear seat, spare, and anything else thats easy to remove.

[EvilcowRoland]

Lean out for a second at over 20 PSI and see if the damage is notable.

While I completely understand what you're saying in reguards to physics and weight shift, you're missing the whole picture. Fluids always try to fill the volume they are presented. On 1/4 tank of gas, when the weight shifts to the rear the gas will actually move faster and spread out more as it reshapes to the back of the tank. Essentially, the velocity makes up for the lower mass and you're getting a lot of energy slamming around in there. The full tank of gas will actually be more stable albeit with a higher mass. So essentially you can negate the 2 (although I'm sure if you crunched the numbers one would edge out the other, in this case the the difference is negligable). I gotta go with Reaper on this one, I'd rather have the extra 50-60 lbs then risk the potential of having a lean condition. It "shouldn't" lean out at 1/4 tank, but why take that chance?

We could always say run half a tank of gas and call it a day. j/k.

[InfinityShelbyZ]

I say a more fun idea is someone actually try this on a real timed run. Thatd be more fun!
