Just got my 4.10s installed with Lidios tune!I have some questions too!

[guccijayda]

hey guys how you doing? well i just got the 4.10's installed with lidios 4.10 93 octane sct tune. Prior to this I ran lidios 3.55 tune with my 3.55 gears and I really cant feel any difference with the 4.10's. I mean it feels fast, but not really a noticeable difference but maybe thats just me! I heard members on here squeel and spin the heck out of their tires once they put on 4.10's. but I still have the same split second chirp/wheelspin from a deadstop i had with the 3.55 gears tuned and 4.10 gears tuned(although I do have 295/45's at the rear). I was told by the mustang guys that I am going to feel a dramatic difference.


Now my question is ...what is a sure-cut way to figure out that I currently actually DO have 4.10's on my car? Because I felt a great improvement with lidios tune with stock gears, but then I couldnt feel a difference from the 3.55 tune to the 4.10 tune with 4.10 gears.

NOTE: Before I got my car tuned, I could not chirp my tires from a dead stop whatsoever with my stock rear bfg 245's or even my current 295's!! Once i put the lidios tune for the 3.55 gears, WOW WHAT A DIFFERENCE! I can chirp my 295's and it feels so much more powerful. But like I said I couldnt really tell any difference once I got the 4.10's put on.

Also, I am for sure that I did not have 4.10's prior to installing my 4.10's so that is out of the question.(just 4 the fact that prior to any sct tune, I could not spin tires 4 squat, gears felt long and stock, sluggish off the line, etc)

[O's Fan Rich]

Put the back end up, both wheels off the ground.
mark the tire. mark the driveshaft.
rotate the tire 1 revolution while counting how many times the drive shaft rotates.
If you cannot "feel the difference" in going from 3:55's to 4:10's something is wrong.

[guccijayda]

Heres the problem.lol. I installed lidios tune with my stock gears and tested it only for one day(what a difference!) and then I went on vacation after that. once i got home, I went straight to the 4.10 install. So i only tested lidios tune with stock gears for literally one day. So it might just be me not noticing a dramatic difference. Do you know what mph the 1st and 2nd gear shift with lidios tune on 4.10 gears?

No idea. It's been a spell since I drove mine.

[Cougar_Marauder]

My baby is in the shop right now getting 4:10s put in (waiting for new axles :mad2:) I should have her back tomorrow or Thursday. I am using Lidios tune so I will let you know how much a difference it makes and when abouts it shifts on a WOT run. Did you get the gears that were in there back? Did you check the new ones before you had them put in?

[justbob]

My Trilogy w/3.55's - 12.9

BradleyG's Trilogy w/4.10's - 13.1

Both very comparable cars

So to answer question, I personally don't see any gain.

Obviously I'm wrong because its an upgrade no matter how you look at it. I would just have to think that there would be a huge difference between the two. In my Camaro I went from 3.42 to 4.10 and it felt like out of control fun, night and day difference, but also a lighter car.

[Pat]

Changing to 4:10's was the second mod done on my car in late 04. I had the 4:10's done in conjunction with a Lideo tune and I noticed a definite improvement in low end performance.

The members of the old .ORG site also raved about how the 4:10's woke their car's up in the low speed/launch envelope.

I would also recommend you check the tire vs driveshaft rotation ratio. You will have to be exacting because there's not much difference between 4:10 and 3:55.

[guccijayda]

ic. I tried trouble shootin a bit and tried running my 4.10 gears with lidios 3.55 tune. The car still ran fine and switched gears smoothly and in WOT it would shift a tiny bit before redline. But when i have the 4.10 gear tune on it it will shift fine and smooth too but in WOT it will shift gears a lil after the redline.

Does this unfold anything about my gears if they are for sure 4.10s or not?




BTW i bought these gears from summitracing. and they are the 4.10's for sure! But.. I'm just not persuaded by the performance cus it feels the same. Jeez I spent $700 dollars on the 4.10 gears and I feel as if I should have just sticked with the 3.55's and the lidio tune because i cant feel a difference with my 4.10's with lidios tune, atleast not a significant difference.

[guccijayda]

Bbbbbbbbbbbump

[Glockafella]

Lidio likes the shift point on the marauder a little past the redline...NEVER BEFORE @ WOT!

[Glockafella]

I'd say you probably had 4:10s before and didnt know it. The little bit of perfomance your noticing is you have the proper tune on your car now!!!

[guccijayda]

Na i most definitely didnt have 4.10's before. 4 A FACT!!! gosh im so puzzled.

[Glockafella]

Well then your shop didnt install the 4:10s you brought them...

[Glockafella]

You should definitely FEEL a difference between a 3:55 rear and a 4:10 rear...

But then your 4:10 tune is shifting properly and at the proper shift point...:help:

[stangracr]

I would drive the car more. These cars are heavy and with 295s you might not be able to put them up in smoke easy. I also think a supercharged car would like the 3.55s better then n/a car does. Go ahead now and get a stall convertor then you will really feel the difference. If you dont want to mark the tire and driveshaft put you 3.55 tune in the car and run the hiway with the cruise set at 60 and watch the mile markers. See if your speedo is off. If it is with the 3.55 tune then you know the gears are changed.


ed

[DOOM]

Who did the install on the 4:10's?
Did you get your old gears back?
I would have had my shop pull my old gears FIRST and then show me the difference before putting the new ones in.
That way you would know for sure what you had and what you now have.

[rayjay]

I had 4.10s installed last month. Night and day difference.

[Bradley G]

Correct about our best ET's.
But this may lead people to believe your car will run slower with 4:10's.
Remember, different tracks different day.
My car is faster!:D

I havea gps and i think it has the speedometer on it. So if the speedo is off by a little it means its 4.10 gears? Because im thinking it may be off by a little already by the irregular size of my tires. Wouldnt the 4.10's also only effect the speedo by a little too? correct me if im wrong

I got it done from excessive motorsports in mannasas. They got the job done in 2 1/2 hours and I seen so many cobras. I have the old 3.55 gears also. I'm thinking of finding someone in the cam area with 4.10's to test drive it. Im puzzled. I got the correct part from summitracing and the 4.10 gears was correct for sure. puzzled ill hopefully get an answer to this.

[Stranger in the Black Sedan]

The 3.55->4:10 won't affect your speedo now that you have a 4:10 tune (factors in change in drive ratio in the tune). What size are your tires? You should have told your tuner your tire size and that should also be factored into your tune.

[ctrlraven]

Your car might be fine and it's just you. I'm sure the shop did their job since no one has had any bad experience from them yet. Try returning your car to stock then upload the 4.10 tune again, anything is worth a shot.

What other mods do you have? If you are running a 295/45-18 tire the revs per mile (how many times it rotates in one mile) will be around 709-710.

[guccijayda]

thanks guys. My current mods are. jlt intake, flowmaster 40's, 4.10 and the lidios sct. Yea i know they are great guys! I believe the tire height i have is only 101% compared to stock and there are several others on the forums with the same tires.

ill try to do that ctrlraven. Im going to return the car to stock. Should my car drive and tranny drive like crap with 4.10s and stock tune?

[ctrlraven]

No just return the car to stock then upload the 4.10 tune back up a few mins later.

[guccijayda]

but if i return it to stock and the car drives like crap, doesnt that imply i have 4.10s? Correct me if im wrong

[ctrlraven]

Yeah the speedo and shifts will be way off.

[guccijayda]

Yeah the speedo and shifts will be way off.


I put it to stock and drove the car about a mile around the block. For some reason it feels like my gears is long and feels like the ratio of my stock 3.55's. And alot slower. But whwen i put on the 4.10 tune. It is alot more jumpier and the gears seem shorter. When i say the gears seem shorter i mean the ratios, not anything to do with the shift points, the shift points are fine and a tiny bit past the redline in WOT. Does that make sense? Or is my gears supposed to seem short and the same with either tune because its 4.10's, but just different shift points and such?

[ctrlraven]

You're fine man. I think it's just you don't have much of a reference point to compare the .3.55 and 4.10 with tune to.

[guccijayda]

You're fine man. I think it's just you don't have much of a reference point to compare the .3.55 and 4.10 with tune to.

Thanks for all your help guys. I am beginning to think im fine. I'm thinking its my wide sticky tires with all that footwall leading me to not be able to spin tires as much or burnout. But i definitely feel some power. I'll goto the track asap that will probably answer some questions!:banana2:

[ctrlraven]

The larger tire is the difference. Next step get a PI 3000 or 3500 stall converter THEN you will really feel the difference.

[Stranger in the Black Sedan]

I don't blame him, there are a lot of guys on this board that make it sound like you will go from 15.0 in the 1/4 to being able to reach exit velocity and blast into outer space, just from a gear swap

Gears don't add horsepower, they just fine tune your rpm range relative to road speed. I am sure the shop did not stiff you on gears. If you are that concerned take the diff cover off and count teeth but that is really unnecessary.

I was waiting for your response!:lol:

[justbob]

Remember, running a taller tire LOWERS your effective gear ratio. I don't remember the easy math right off the top of my head. Can someone help out?

[Jolly Roger]

Lets forget about SOP feel for a minute.
Have you taken your car to the track for a before and after run?
For example,
my car with just a tune (no names) went 14.96 E.T. with the stock 3.55's.
When I installed the 4.10's the next week it went 14.51 E.T.
You do the math.;)

[guccijayda]

I'm probably over expectant because I have been so used to my 12 second srt-4 i sold a while back! lol but it's a great upgrade that I'll never regret for buying my marauder.

[justbob]

You must have had quite a bit of work done on the SRT/4.

Nope i havent taken this car to the track whatsoever yet. Planning to asap if anyone wants to come to capitol.

16.0 with an 03' and 3.73's.
15.29 with an 04' and 4.10's.

Yea, there's a difference.

[Glockafella]

Isnt that thing front wheel drive? Why the spoiler?

[Cougar_Marauder]

Wooohooo, i finally got my baby back from the shop after 2 weeks (waiting for new axles, thanks Rick). I can say it is not all that big of a difference, but I can tell. The tune makes most of the noticible difference so if you didnt drive it much with just the 3:55 tune you might not be able to notice. So far so good, I found myself constantly speeding through town since it jumps up to speed with ease :up: Only problem now are the five O..

[JBeezy]

I only read the 1st page, but I feel its just you since you only drove the car once with the tune and 3.55's. I dont feel that enough time to really get the feel of whats going on. Going to 4.10's should definitely feel quicker and should rev a whole lot faster than it did.

I had my mustang stock with 3.08 gears and drove it a while. Then started modding one thing at a time. I went to 3.73's and noticed right off that it rev'd faster especially from a dead stop. I know this isnt a mustang but making the gear change you made should be very noticable. If you went from 3.55's to 3.73's I'd say you probably would notice too much of a difference at all.

[ctrlraven]

We really need to start making some new threads. A lot of people are bringing back stuff from the dead. lol

3.55 to 3.73 is a 5% difference, 3.55 to 4.10 is a 15% difference so it is a lot easier to recognize the difference. That's why 3.73 is not recommend since it doesn't offer the performance per $$$ compared to doing 4.10s.

[bocat187]

i went from from 3.55s to 4.10s and its a big difference trust u should be able to tell the difference

[RocsMerc]

I know this is an old thread, but I might be able to contribute something. With 3.55 gears, I could go WOT at exactly 30mph and the car would downshift to first and pin me in my seat. With the 4.10's, I have to be going about 24mph to get the same feeling.
