Streetability of big stalls

[Five Oh Brian]

Cant fix stupid

Wow; judgmental aren't you!?!?

I'm putting together a different combination than a couple of know-it-alls on an internet forum. That makes me stupid?

It's one thing to have an opinion. It's quite another thing to ram that opinion down everyone's throat and belittle people who don't share your opinion.

Ultimately, do YOU really give a rat's @$$ that I spent $144 for a set of 4.10 gears? Will it affect your life one iota if 4.10's make my car quicker or slower?

 

[Five Oh Brian]

If memory serves me you were also the guy that thought that 4.56's were the perfect gear for the MT82 but could never get out of the 12's.

That was me. I chose the wrong gears for my '11 5.0L MT. I admitted it publicly here in the forums and moved on. I've made plenty of great gear changes over the past 30 years in my other cars. You can't win them all.

You strike me as one of these guys that just throw parts at a car without really thinking it through. Kind of like the guys many years ago that threw a Holley 850 cfm double pumper carb on a bone stock 302 and thought it was a perfect fit.

You couldn't be more wrong about me. I methodically choose parts for my cars that work in harmony with each other in the same operating range. I can't afford to just throw parts at cars, so I spend a ton of time researching mods before I choose them. Just because I don't pick the same parts as you doesn't mean my choices aren't right for my goals.

I'm just going to say get some results rather than just talking about it, which I do believe you have every intention of doing. Here's a target for you that has a LOT of similarities with your car:

2013 auto/recaro/brembo/tech package. Way less converter(3C) than your 5E, stock 3.15 gear, off road X/catback, no suspension other than a Roush upper control arm, wheel/tires, driveshaft, front swaybar removed, good calibration. Nothing else, no weight removal, engine 100% stock down to the paper filter. +950DA not some mine shaft hero run.

If your theories are correct about way more gear and converter you'll tear him a new one. Get after it, let's see it.

Thank you for the productive comments. The GHIG '13 in the video certainly put down the kind of numbers I'd like to see out of my car someday. That GHIG '13 weighs a lot less than my '14 GT, though, so I'd need some extra oomph to match it. My car is a 400A (Premium GT) with dual heated power seats, heavy glass roof, Shaker Stereo, 19x9.5 wheels, etc.

You are correct that I'll post up results soon. I am a regular at our two local dragstrips. They won't be open again until next month, so it'll be several weeks before I can make some passes.

What tracks do run at Sorry for the rude comment its a local phrase. but this has all been done years ago. Ive tested 315. Then 410. Then 373 then 331. 331 was by far the best. If your up north by me midwest. we can meet up for some testing i have a big heavy car too full leather heated seats runs 11.7 11.8 all day bolt ons stock intake stock suspension. Upgraded shocks and springs this year. Im in the Midwest region. Pm me your tracks

 

[FIVE-OH]

That's not a fact; it's simply your opinion based on a small sample of vehicles, just as my assertion that 4.10's are quicker was based on a small sample of vehicles.

No, actually it is a fact. Without getting into "race cars", ALL the quickest 6R80 Coyotes are running stock gears or 3:31. I am not going by just this forums old list...good luck.

Do we see a Déjà vu in your future ?

Thank you. It's all good. I run at Pacific Raceways (formerly known as Seattle Int'l Raceways) and Bremerton Raceway. All I want out of my car is consistent 11.50's in the cool spring & fall days, and to stay under 11.99 even in the heat of summer. I'll need a few more mods to get there, but it shouldn't take much. My car is a daily driver and I use the back seat so I can not put a cage in it (required at 11.49 and quicker).

NHRA rules for 2008-newer cars is no cage required all the way to 9.99 as long as it's not a convertible

Our local tracks require a cage for all cars 11.49 and quicker. Sometimes they look the other way, but most of the time they won't sign off your tech card. The 2013 NHRA rule change only applies to "unaltered" 2008-newer cars, so our tracks are interpreting that as 100% OEM stock. Modded cars 11.49 and quicker must have a cage, in their opinion.

That sucks we regularly get away with even 9.80's on our tracks here in Texas

Same tires? If you are both on stock tires then he doesn't stand much of a chance since it won't hook.

m&h 275/50/17 drag radial. He lets me use his when I'm out there.

With 4.10's it wont hook well no matter what tire is on it. With the 1st gear in the 6R, it will spin and shift to 2nd gear almost immediately, then it will hook

With the stock stall anyway it doesn't spin in 1st.

 

[FIVE-OH]

I think he was thinking on the street, not track.

My car with stock gears will blow the tires off on the street, on a well prepped track I nearly dead hook...still amazes me.

Wasnt this thread about stall converters?

Nope never.

Glad I'm not the only one who noticed the derail.

No, actually it is a fact. Without getting into "race cars", ALL the quickest 6R80 Coyotes are running stock gears or 3:31. I am not going by just this forums old list...good luck.

I can think of only one exception, Aaron Lail runs a 3.73 gear and has been something like 10.89. But he'll tell you the only reason that gear is in there is for the 1/8th mile tracks he runs on most of the time.

Just an observation about the big stall converter and 4.10 gears for daily driving that I've noticed. I live in a hilly area with some steep grades. With the 3.15 factory gears, the stall converter would unlock going up steep hills, no matter how light the throttle position. With the added torque multiplication of the 4.10 gears, the stall converter stays locked going up steep hills (unless I mash the gas to flash the converter). This is a big plus for my daily driving that I hadn't counted on.

Also, with the 3.15 gears and big converter, fuel economy was 11 mpg city, 27 mpg highway @ 60 mph. Switching to 4.10 gears changed my fuel economy to about 13 mpg city, 24 mpg highway @ 60 mph. I lost a few mph on the highway, but I live 4 miles from work with 95% of my entire driving in town, so this will help my overall fuel economy dramatically.

Overall, the big converter hasn't hurt drivability at all, and actually makes the daily commute much more entertaining.

And, for those who drag race, the converter dropped six tenths off my 1/4 mile ET. I had a 1-pc aluminum d/s installed the same time the converter went in, so that six tenths is actually for both mods, but I'm fairly confident that the converter was the vast majority of that improvement.

Update time, as promised, and many of you were correct that going to 4.10 gears wouldn't make my car any quicker in the 1/4 mile vs 3.15 gears. Ran the exact same Bama tune (except changed for the gears) and ran the same 12.0's as before. Loaded up Mike Rousch's tune and went 11.90's all day long (11.93, 11.95, 11.97, 11.98 twice, and 11.99). I haven't datalogged for Mike yet, so I suspect he can make my car even faster once I do. Best trap speed last night was 115.76 mph, so it's making good power! Race weight was 3,800 lbs with me in the car per the weigh station on I-5 on my way home from the track.

I tried a variety of launches with the stall converter and found that now my car traps highest by holding a lot or rpm's against the brakes at the starting line (leaving off idle was the slowest).

Here's my best slip from last night....

Cooling off in the pits. My Ruby Red '14 on the right and my friend, Bob's, '12 Procharged GT on the left...

So, 3.15 gears are just fine (like everyone told me). Big stall converters really wake up our cars, though. Biggest bang for the buck after forced induction!!!

Still seems off for your mods. That should be a 11.5 car.

 

[2011/5.0]

Op really needs to get mike some logs Im sure he will put alittle more timeing in once he knows it looks safe. And he can refine shift points. That should get you in 11.7. 11.8 range
