Single top mount turbo - Supporting mods

[NGOT8R]

I’ve made the decision that I will be adding a single turbo to my 2019 Bullitt. I would like to hear from the turbo folks, what supporting mods are mandatory to allow for a good margin of safety? I would also like to know how much power you guys are making on 93 and E85?

For the single turbo cars, did you guys have to do a wire tuck in the engine bay to keep they clear of the turbo headers. Thanks.

Without getting into too much detail I can just suggest to stay away from single turbos on these cars unless you just want a full out racecar.

I do want it to be quick and fast. In looking at everything that I already have done to the car, I decided on a single kit, due to fewer components. I am also going to retain my nitrous system to help it spool up when needed.​

I don’t know if this is the case with the BL Fabrications single turbo, but I have seen where some turbos require a wire tuck in the engine bay. I’m expecting there to be some additional fabricating work needed. I just hope it’s nothing too crazy.​

You may be the first with a single turbo street car on here, especially in a Bullitt.

I think that it depends greatly on who you have building the setup and who tunes your car. I know people who have completely streetable single turbo builds making 600 on 93 and close to 700 on e85. But I also know people making 900 and their boost is only manageable with drag radials.

I will handle the install myself and then find a reputable tuner to handle that aspect of it.

I agree that sticky tires will be necessary.

Any Coyote getting boost NEEDS The Oil Pump Gear & Sprocket upgrade generally speaking. Are there people out there with boosted cars without them that aren't having an issue? For sure.

But, for added support and insurance for a lack of better term; it's the way to go.

Is there a power goal you're looking for? Why single turbo out of curiosity?

Power is gonna be based on tuner and fueling, so just really depends on how much you wanna turn it up safely.

If you’re doing the bl fab kit you’re going to have to get underneath your dash to relocate the harness on th drivers side of the engine bay, gonna have to tuck the harness on the other side of the strut tower

The way single turbos deliver power you aren't going to make 900 and be able to run street tires, drag radials will be required. I honestly would recommend a twin turbo setup and just run a lower psi. You still get to that 700 hp range but the boost lag is much more manageable and has better power delivery and reliability. If you want to turn the boost up then you get over the 1000hp range!

But if you're dead set on single turbo just make sure you change the oil gears!

Thanks for the reply Jake.

My power goals are as follows:

- 850 whp on 93 fuel
- 900-950 (if it can be done safely on E85)
- 750 whp with boost, plus a 75 hp shot of nitrous on E85, since I already have nitrous on the car and don’t want to remove it.

I prefer a single turbo because it has less components and will also provide more room for tweaks, if plumbing has to be altered to fit around other components installed on the car such as my external transmission fluid pump. A twin bottom mount setup would likely interfere with supply and return lines attached to the tranny.

Is the only reason you want single turbo for space reasons?
I am curious why not twin top mount, or twin bottom mount, as single is not going to outshine twins on low hp, relatively speaking as i dont think the small twins(which arent that small LOL) would be more than enough
If space is the issue, i would almost say a centri is better? But im assuming the centri power band isnt what youre after

Top mount twins would be tight. I would also have more components to service with twins. I’m already going to have to move a solenoid and clutch lines for the clutch slipper device on the driver’s side.

I don’t street race at all, so I’m not too worried about losing any power down in the lower rpm range. I figure at the track, I will have the car up on the 2-step anyways.

If you size the turbo right aren't a single and twin setup going to have very similar power curves?

I’m not sure about that, but I’ll surely look into it to see which turbo would best suit my needs.

Also I was re reading and you need to give up on 850 on 93, 93 can barely support 700 regardless of what you read in this forum.

Honestly you should just but a G3r or a g4 and eliminate a massive amount of headache
