Hellion TT Top Mount for 18 GT

[Hitani]

I will be ordering in couple of months the Hellion TT top mount kit for my 18 GT. On top of that, I will be changing the injectors to either ID1050 or ID1300; change the driveshaft to QA1 Carbon fiber; change the fuel system with Fore Innovation (no BAP); Brisk plugs; exhaust setup will be Hellion headers + Corsa Extreme cat-back; Barton or MGW short Shifter (not sure which one yet). ENGINE and TRANS will remain stock! My goal is to be able to push 700-750 whp. The car will be mainly street driven no track. Will my car be able to handle that power with STOCK engine and trans ? Let me know if I need to change any other stock parts other than what I listed above for my goal power.

First of all that fuel system is overkill for 700-750 from turbos. That’s like <8 psi, so the stock fuel pump and maybe some 38 lb port injectors would do it fine on 93 octane.

I have 3 friends with Whipple superchargers, plus myself, all on 2018-19 mustangs. We’ve put a lot of hard miles on these cars. All have stock engines and transmissions. So far the only parts we’ve broken amongst the 4 of us were 6 catalytic converters and one mt82 shift fork. My guess is your mt82 won’t fare much better.

Same as Mike said above 1300’s is way over kill for what you want to do. I’m running 1050’s at around 900 and still have a little left in them before I need to upgrade. I would skip the drive shaft and put that into suspension mods. Just my 2 cents…

Isn't it also true that turbos are easier on the motor since they better follow the factory torque curve?

What supporting mods did you have to change/add as well ? I have two reasons why I mentioned fore fuel system. first, I'm trying to have my supporting mods to be able to handle +1200 whp (want to hit those numbers in future, once I do work on the engine and tranny) I dont want to be buying mods twice. Second, I heard that the maximum hp limit on the stock fuel pump on the 18's is around 700-750. I could be wrong. but if that's right, I don't want to be at the maximum limit of my pump just in case anything happens, I know my luck lol. Oh and btw, I broke the shift fork once on my FBO setup, so yeh, definitely shitty forks from Ford. Did you end up getting an upgraded fork or you stayed with the stock one ?

Also, are you running on the stock pump? Any BAP installed ?

I Appreciate the feedbacks !

I will stick with the ID1050 for now then. Are you on stock fuel pump ? What supporting mods do you have installed to handle that 900 ? Are you on the stock drive shaft ?

I'm just really trying to have a TT build that can handle 700-750whp with the right supporting mods, I just want it to last as much as possible lol.

I appreciate the feedback!

Honestly with a proper tune and fuel the motor will be fine at that power level . Being a manual your clutch and trans will be the weakest link much like my auto trans was. I am running triple 450 fuel pumps (due to what my goals are) with a return style system and aftermarket fuel rails on e85. I also have the full Steeda stop the hop kit, BMR drag springs and a good set of drag radials to handle to power.

I would say turbos are easier on the motor at a given power level because it doesn’t take as much boost/air to get there.

Good tires and rear subframe alignment/reinforcement is a must do.

Have you spoke with Hellion yet???
Have you spoke to a local tune shop??

I originally planned on going with this TT kit when I bought my S550.

Hellion's tech support is awesome. They should provide all things air/fuel/spark and in the order its needed to be safe as you increase power. Tell them your short term power goals, long term power goals, and current mods.

After that.. I recommend spending money on getting 700 safely to the ground. Engines and transmissions don't like summersaults or telephones.

Scratching the surface of what your posted build list will result:
I recently boosted mine with the Roush kit and a BAP on 93. It's supposed to make 750 bhp. The BAP is more precaution than necessity. The rest of the car is basically stock. It's stupid fast for public roads. The car will not go straight if I punch it in 1st, 2nd, or 3rd. There were a few butt puckering moments this fall.

My IRS support bracing and alignment kit jus arrived which is step 1 of the stop the hop kit. Probably going with Michellin PS4S once the Goodyears are cooked.

Is it a daily driver or nice weather car? If not already, run a DR out back so you can put the power down. BMR CB010 + CB762 or Steeda STH like others said will also help traction.

Good luck with the build!

I reached out to Hellion last week asking them bunch of questions. Waiting on their reply. As far as tuning, I'm leaning towards Lund. Any suggestions ? I'm currently FBO with Lund tune, had no issues with them in the past. I will definitely look into the rear support mods, this was not on my list. Any reason why you changed your mind on the TT kit for your S550?

It's more of a nice weather car, I don't daily it. When yo say "DR" do you mean Drag Racing kit ? like this one? https://www.lethalperformance.com/b...YBpAlnKbCyK9WF4cACMmPECcmQJMaHRBoC_5EQAvD_BwE

I heard that the maximum hp limit on the stock fuel pump on the 18's is around 700-750.

A turbo 12/1 compression engine is going to be about as efficient as they come, meaning it will make a lot of power on a little fuel. The power limit you state is about right supercharged, but turbos will do more with less; probably about 10%, maybe 15.

Did you end up getting an upgraded fork or you stayed with the stock one ?

That car got a Magnum XL.

Also, are you running on the stock pump? Any BAP installed ?

dw400 on a bap will support probably up to 15 psi on gasoline, which is a lot of power on a turbo setup.

I would love to have the Magnum XL, however its not on my budget for now. Will throw one in future for sure. Hopefully my trans last, I mean I don't drag my car at all. The most I do is normal street driving and roll racing occasionally.

dw400 on a bap will support probably up to 15 psi on gasoline, which is a lot of power on a turbo setup.

This is exactly what I was thinking, might take this route and save the Fore fuel system for higher hp numbers.
