Hellcat out, Mustang in

All motor. No boost, no nitrous.

Just some E85, headers, Cobra Jet manifold.

Dip came from traction control trying to engage.

This 10 speed auto GT is faster than my old Charger Hellcat when it was stock.
 
What are your thoughts on the auto trans in that Mustang? What does it use.

I've considered selling the Golf R and picking one up.
 
This article pretty much explains the benefits of the 10 speed auto:

https://www.motortrend.com/news/why...automatic-is-so-much-quicker-than-the-manual/

In my experience it keeps the car in the powerband at almost any given instant. The 5.0 engines were always known as high revving monsters that makes most of its power up top, while feeling less than torquey down low. That's still true, but the 10 speed hides the lack of low end feel very well.

The car's fuel system is also E85 ready from the factory. Just need a tune, that's it.

If you do get a GT 10 speed, I would advise not to do what I did and avoid the 3.55 rear gear. The standard 3.15 rear gear is so much better for the 10 speed because it keeps you in the lower gears longer, where there's more torque multiplication. Alot of guys that bought 3.55 gear option thinking it will make the car quicker (it does, but only from 0-60), actually end up running worse qujarter mile times than 3.15 equipped cars. And so they swap em out.

I know you can make Golf R's fast, but the GT with the 10 speed is so ridiculously quick with E85 and some really minor mods (like just mid pipe), it'll be more than a match for most modded 4 cylinder turbo cars you meet up on the street.
 
Pardon my ignorance here, but don't you have to replace all nitrile seals and rings with a different material since you're using such a high ethanol mix?

I would assume it would ruin the seal eventually if you don't
 
Not for the 2018+ models, the fuel system was revamped/upgraded. Absolutely nothing needs to be done to run E85. The car even comes with flex fuel programming, just never implemented (thus why you need a tune).

I run straight E85 with a straight E85R tune (non flex, I just happen to get good E85 in my area that always tests above E80 to E90. A straight R tune ramps up timing much more quickly than a flex tune), about 4k miles on the car no issues. Others have ran it 30k + miles on E85 as well. Just occasionally run a tank of 93 every few months to clean out the fuel injectors, is all.

Can you switch to no tune and run regular gas also if needed?

I know in Colorado E85 is available but it's not everywhere; and if you go outside of the Denver metro area along the major interstate, you won't really find it. No bueno for a roadtrip.


edit: ah I see you run 93 every few months anyway so yeah no problem there. That's a great setup.

Well in my case I used two tunes, an E85R tune and 93 tune. Whenever I fill up with 93 I just load up the 93 tune, and vice versa.

That's in my case though, tuners do offer a complete flex tune where you can fill up with whatever and the car will sense whatever ethanol is in there and adjust accordingly. You can run any mix of gas and E85, even E85 that tests E50.

I don't prefer this option because it takes longer to ramp the timing up. There is a big difference in low end power between a flex tune and E85 R tune (up top they are the same), so having an E85R tune is more fun to drive everyday on the street because of the extra low end power. Of course this means I have to make sure any E85 filled is actually E80 and higher, can't be lower. I carry my own tester around when filling up, and there's a facebook group for E85 that reports what stations have the best E85 and what they test at.
 
Wish we could get E85. ACN91 is terrible gasoline. I used to have no problems holding the timing with exxon 91 in montana, enough to trap 130mph. After moving to nevada, I'm stuck putting boostane in it otherwise I get knock.

Getting a Golf R into the 10's takes considerable work. You'd have to do a turbo swap, and even then it takes a bit more. The REVO IS38 kit runs 11.2's with all the associated hardware/components along with it. Maybe with e85 or race gas it'll hit 10's. I'd be happy with 11.20's, but even that would take a lot of money/work. Tune and downpipe will get me into the 11.80's likely, and that's where I'd stop on that car.

Back to the GT though, it's quite tempting. Need to take one for a drive. Im not a fan of e85 though, so I'd limit myself to 93.
 
What are your thoughts on the Mustang after owning it for a while? Any issues? Regrets? How's the auto trans?

What work have you put into it so far and where are you at with 1/4 mile times?
 
No love for the Camaro SS?

Sure, I like them quite a bit. They just have ugly interiors and feel like you're driving a tank inside due to the windows/visibility. :p

If I were looking for a track car, I'd take the Camaro SS 1LE. For daily driver/drag car, the Mustang seems more appealing.
 
Have to agree, the Camaro is just so damn bulky.

I've been waiting for the Subaru to sell, and 99% chance I get a C6 Corvette, but I have a sick addiction of watching 2016+ Shelby GT350 videos. That flat-plane 5.2L screaming is absolutely beautiful, plus it has the modern interior that I want, which is what pushed me away from a C5 Z06.
 
Yeah, you definitely don't buy C5's for their interior. :lol:

If you do look at C6's, just make sure you do a 2008+ if it's in your budget. In 2008, all of them got the LS3 motor and the TR6060 diff/trans from the C6Z.

I've got a feeling you won't really like either one :p

It's been a year and half and it has only 4k miles on it so far. Miles will be kept low since I work from home all the time now.


I've had zero issues with it despite all the mods I did to it. I only needed to take it in for an oil change once, that's about it for maintenance.


I actually love this car all motor. It's faster than my Hellcat was stock. I surprise alot of cars that want to give me a run on the highway (though to be clear, I don't go to street racing events anymore. I just drive and whoever wants to randomly egg me for a race, cuz Mustangs are targets you know, I oblige :lol: ).


I posted my dyno previously but it made 502whp with headers, intake, cobra jet manifold, and E85.



I did take it to the track but the time wasn't good. Only got one run in because it was crowded, and I messed it up. It ran 11.2 @ 124. However, that was with some real bad wheel hop and the ABS momentarily closed the throttle body mid run in 3rd gear. Without the throttle body closing I would have easily hit 10's at 127-129. I was supposed to have disconnected the ABS sensor before running so this wouldn't happen but I forgot, and never had a chance to do another run. I won't go back however until I put on stronger axles and some kind of wheel hop kit first, that wheel hop off the line was terrible.



The 10 speed auto transmission is holding up great. The CJ manifold allows it shift at 8k rpms, and the car really comes alive at the 4k mark, pulls so hard it's hard to believe this is an all motor car and not turbo/supercharged. There's quite a few 10 speed cobra jet manifold cars nipping on 9's at 135+ with some minor weight reduction and suspension work, but I like the car as it is (back seat and all).



Shifting is very harsh when WOT but that is the nature of the tune. The car will chip the tires from a 2-3 shift and 3-4 shift (hence why traction control wants to close the throttle body and needs to be turned off).



There's nothing else I plan on doing at this point other than axles, which I won't do until I know for sure I'll be returning to the track. I don't have any issues with wheel hop on the street, even with the NT05Rs I have on there.
