its still off
for the 4.10s and 4.30s it would be more like
4.10s 2500
4.30s 2650

those cal. are not all that good

you have to go by real world numbers

like I said before in 5th gear a car with a 3650 is at almost the same rpm at 75 with 4.30s that i am with 4.10s

Holy crap I cant believe I just did that!!!

those last two numbers are supposed to be in the 2k's not 3k's... I'm editing it now... sorry!!

See what happens when we try to reply to fast? lol

its not about drag racing it about driving and I will tell you this and most that done this will agree
most guys that go with 3.73 change them in a short time time to 4.10s or higher

DONT FEAR THE GEAR

I dont want to sound like a jerk
but a few of us as told you the same thing and you dont want to listen and the guys telling you this know what they are talking about
if you want 3.73s thats cool its your car but I would never go with a 3.73 gear in my car its not worth it to me

last but not least
do you know with the price of cams and install is going to be about 1000$(for 15 hp) you dont have alot of stuff that are needed for the cams to make real power

plus is you should get valve springs to even if the cam specs say they are not needed cause it cost an extra 185 dollar for the springs but if one should break the how much do you think a motor will cost I can tell you now ford WILL NOT COVER BLOWN MOTOR if its cause you puts cams in it that caused it to know

you say you have done a lot of research on the mods you want but I dont think you have otherwise you would know this

The only reason for the 3.73's IF I even gear it, is because I dont want such high rpm's on the freeway... and since I dont race, I have to find a happy medium, thats all :)

I tell ya what... if this car wasnt my primary get around.. I'd go straight to 4.30's!! I agree with all of you on the gearing totally.

Realize this... everyone (including you explicit) who says to go with 4.10's or 4.30's spends their weekends at the track :)
I dont, so there is always a but or if factor involved... lol
I'm not as extreem as some of you, infact I am happy with the stock gearing.. ha!

Yes I know the valve springs are a must. And yes I know the cost. But as far as installation... my bro and I will be doing the install. (He has done the cams on his mod, along with many other motors.. he works at Ford, in service) I've rebuilt a 302 and a 351.. so I have enough basic know how :) Hopefully!

Plus.. cams aren't that hard of an install, now that they're up top :) We'll do it in a weekend, hopefully!
but then again.. you might see me posting how to's on here when it comes time to do the install... lol

yes and no the cams are harder to time then the 5.0 and valve spring removal is a pain with the heads on the car
plus with most cams on the mod motor it needs to be tuned just idle

and if your bro know so much about mustangs why are you asking us for simple info and why did he tell you they have 265rwhp?

dont get me wrong its your car and you must do what you want and will make you happy I just know from exp. that alot people that listen to ads and magazines are not happy when done and spend 2xs they money on the same stuff
like gears the 3.73 was great for a 5.0 but they suck for 99+ mod motor even if i was not a drag racer I would still go with 4.10s just cause of the fun factor on the street. IMO

i had my 00GT for 6 months before putting in my 4.10 and I only went to the track with this car 1 time in that 6 months cause I had a 87lx that I raced so as you can see the 00 was my street car at the time and I would have been kicking myself if I went with 3.73s
but I sold the 5.0 to help fund the 00 cause of how its

yes I have a few hard core race parts on my car that poeple think are not streetable but I can have just as much fun on the street and I can take a road trip across the country if i wanted and it not be a problem

what i am and others are doing is just trying to help you from spending money on something most people would not like

My car is my daily driver and hardly ever sees track time (T-45 in my car, so yours will turn lower rpms). I love the 4.10s. Why are you so afraid of turning a little higher rpms on the freeway? It won't affect your gas mileage by more than 1-2 mpg in my experience. I have driven over 1000 miles in a weekend with my 4.10s and it's not bad at all. You need to drive or at least ride in a mod motored car with gears. It's not like back in the day when everyone ran a 3-speed auto or a 4-speed manual and if you geared your car aggressively it was almost topped out in the 1/4 mile.

agreed:D
and before it get said no it does wear on the car more
cause even though your at a higher rpm the motor is under less load:cool:

ok guys, once last dam time. Gears are going on on Friday on my car. I am planning on the FRPP 3.73's due to plans to add nitrous. Do you guys agree with this assesment, or should I just go with the 4.10's. I am hoping I can just trade them when I get to the shop as they have them in stock if I decide on the 4.10's. A couple of hundred more rpms with the 3.73 is nothing.

You know, Ive been thinking, how often will I be actually pushing the N02? Most of the time, it will be non-NO2.

Give me you most honest opionion.

Well brothers mod was a t bird... auto.. so it's different.

And (dont laugh) but he didnt tell me 265rw... my mistake and blamed him.. lol

As far as gearing goes.. I'll hold off all together untill I can find someone to ride with who's already geared :)

Thanks

You want my honest opionion... run the 4.10's and don't look back! For someone starting to play with the N2o, you will most likely not go over a 150 shot. After a 150 shot the motor will start to need more of an agrasive tune for the spray and become more criticle. Not to say that it won't be criticle with less but alot less forgiving at that point, and the most you will pick up on, will be a 150 shot. Most people start off at a 50-75 shot and work they're way up. Usually at the 150 level people start to either back off (because they know better, or just worried about their tune.) After 150 shot the point of dimish is not quite there unless its cam and built for it.
So to wrap this up, run the 4.10's and use the nitrious when needed. ;)
My.02's

Thanks 420! Anyone else? I am really open on this issue.

Everyone seems to agree.. 4.10's

Let me know when they're done man... gotta know how you like 'em :)

It'll be great input coming from someone fresh off the stock gears! I wanna know how 1st gear changes for ya.. lol

Make sure to post the results, please :)
Thanks!

Oh yea....Blake
When you spray it with the new gear...a bit of warning..it will climb faster (through the rpms) then if you revved it in neutral on motor!;) ;) :D :D :D
You also might hurt those pretty new tires too!:D

I'm getting some 3.73 installed in a couple of hours. :D

Looking forward in having my speedo all fluffed up.

420nitro, you crack me up. Those tires are toast! Lets hear it for $116 each for 285/40's from Tire Rack.

I hope I can shift that fast....ya hoo!

IF it is your first time to spray a mod motor, AND its a standard, be SURE to have a WOT and WINDOW switch. IF you're spraying and you tach out (hit the rev limiter) you will have some MAJOR problems.....

BTW, if you stay N/A, 4.30's are the way to go:D

-Will

Tarzan:

I am planning on using the Venom system. It has a WOT switch, but no window switch. The system is a very safe system as far as nitrous goes.

If there is not window switch I wouldn't do it man, thats all there is to it. Unless it has some sort of safety mechanism that I don't know about.....


If you hit the rev limiter (could happen for a variety of reasons, slow shift, missed shift, slipping clutch, etc...) and you still have some juice sprayin, you'll be lucky if all that goes is your lil plastic intake.

-Will

Very good point!!!!!!
I just assume people have these things when they get nitrous kits but alot of people are unaware of such devices! I couldn't tell you how gratefull I am of mine.
Thanks for pointing this out. Alot of the new people to nitrous should have this in there cars.
IT SHOULD BE PART OF THE KIT!

Glad I brought this up then. And we have a problem that most 5.0 owners don't face. THE PLASTIC INTAKE!!!!:eek:

It'll go in a heartbeat w/ a N2O backfire......

not to mention the heads and internal parts have been known to bite the dust

-Will

I say 4.10s and dont look back

and I agree window switch or dont spray

Thats why I always run a NOS dry kit or a plate between the upper and lower. I don't believe they make one for the mod motors but the new fogger is what I would get. I do not favor fuel going threw the upper intake. I know that people don't like the dry kit, but I have never had problems and every car that I put the kit on...never had problems. Everytime I saw someone that messed up there motors with a dry kit..messed it up themselves! YES, IT WAS USSER ERROR!
My experance...I am sure people have seen different. Use what works for you then.
My .02

almost all the nitrous cars I have seen blow were due to usser error in one way or another

both wet and dry can be safe if used right and the right saftey equipment is in place:cool:

Very true, but how many of them were from a nitrous backfire due to fuel puddling in the intake?

I have never seem it happen when they were using a window switch(thats was working right)

Good point guys! Yes, I am going with the 4.10's!!! I have 4.10's on the way and my 3.73's are going back.

My chip is still missing in action. I shipped it back over a week ago to get re-burned and it has not turned up. Can you believe that? I insured it. It appears that it may have gone to an old PO Box that the company does not use anymore...they were supposed to hunt it down today, but I have not heard anything.

The Venom N02 system is probably the safest on the market. It ties directly to the TPS and constantly monitors the 02 sensor. Based on lean or rich conditions, it pulses each individual fuel injector. The system is so safe that they sometimes get complaints that it is too conservative and limits spray too often. This si NOT the right system for the experienced driver looking for SERIOUS amounts of boost. With 150 spray, I have been told to expect 75 rwhp gain.

Rev limiter - I understand what you mean...no fuel with lots of n02 is not a good thing. Especially with a driver new to N02....those rpms can climb pretty fast. I am not sure how the Venom system accounts for this, but I will certainly ask. I will not buy unless it has a built-in window switch or if one can be added or if there is some other type of saefty mechanism that does the same thing.

sorta on the same topic... i have heard from a frew people that its possible to go 90 in second gear in the cobras (i think 01/02 at least) whats the deal with that?

nope, sorry it wont happen

Jess:

I had my 4.10's installed today. Had to drive in the rain 90 miles home, but, they are amazing. What the F was I waiting for? Don't fear the gear! This is the way the car should drive. If I had to do again, I think I would go with 4.30's.

They wake the car right up. 2nd is nice from a start and then all the way past 50+ mph. It feels like I dropped a small turbo in it. Tires loose traction easier too through third. It was a pleasure on the highway.

Tomorrow should be dry and sunny. I will test the car in all gears with my g meter and I am sure I will record higher g forces in all gears especially 1 - 3.

I also got my subframes installed. The car feels brand-new. CJ Pony did the work for me in Harrisburg.

im glad you like them

Cool man! Please post more info once you drive it on dry road :)

So.. how is 1st??
It's gotta be almost un-usable... huh?

I need to find someone close to me who has 4.10's so I can get a ride!

Check out my other post!

IT IS NOT UN-USABLE AT ALL


DO NOT FEAR THE GEAR


like i have said 50xs I have had 4.10s for over a year in a d/d car that sees my hwy then anything I get great mpg and during chicago stop and go traffic it is just fine

I can give you a ride. You'd be surprised how usable 1st gear is if you have decent tires and know how to launch it. I have 450lb/in springs in the back and I can still get it to hold 1st if I slip the clutch just right from about 3k out of the hole launching it to progressively load up the back tires.

Well I dont know whats up with mine.. cause if I take off from 3k in 1st I get lots of tire spin... and I have decent tires!

Hmm.. I slip the clutch too.. oh well.. I'll just have to see when I take that offered ride :) :)
