2023 Mach 1 -Twins?

[Ecruz0884]

Hey everyone. I need some knowledge please! Getting back into a Mach 1, this time automatic, which I’m torn on because I love rowing those gears but hey, automatic is faster.

Anyway, I’m definitely going to turbo the Mach. My goals..high 800whp, as little lag as possible, reliable for years to come and be able consistently run top end with the likes of say McLaren 720s or higher. i.e run 145 or higher in a quarter mile span.

Soooo do I go single or twin? If twin, I’m looking at Hellions’ kits. Is there any difference between sleeper kits or top mount kits? I was swaying towards top mount. 62, 64, 68 or from what I saw others mention 55mm BB turbo?

At the power level I'm thinking do I need to upgrade any other part of the car besides fuel? I don’t plan on launching out the whole, this will be my daily so any races will be rolling.

I’m hoping 25/30k is enough to get it all done. FYI I also want mild cams, and H-Pipe with Flowmasters for that old school sounds or at least as close as possible.

Please let me know your thoughts. Hungry for opinions

Thxs!

Btw I would really love to do this setup on 93 not any blend of Ethanol.

I cant answer the main question re: turbos, but I can say that a turbo car is almost surely not gonna sound like old school muscle. The turbos quiet the exhaust too much and the coyote doesnt sound old school anyway even with h pipe and flowmasters.

High 800s on 93 won't last long. Twins will spool fast and make big power up top. Sleeper kit will keep heat out of the engine bay and is capable of more power than the top mount. Cams are a waste for your goal and coyotes don't really chop anyway.

Turbo is more efficient, on a V8 makes a ton of power but the drawback I would say is reliability (the turbo kit, possible leaks, more complex design for maintenance, etc) and they take away some of the deep V8 sounds. Not saying they don't sound good, but Supercharger just sounds sexy imo. Since you have the auto I would go with Centrifugal it will pull like a freight rain and be more reliable. (PD blowers though are fun as hell and sound great with the whine).

I am sure some turbo guys here can give you better feedback on specific turbo kits.

Also for sure I would go with a E85 tune, probably can flash 93 when E85 not available but I would keep it on E85 as much as possible.

yea the turbo won’t sound old school and definitely the coyote does not sound like the old school stangs. Sucks. I was just trying to get as close s as possible. Thanks for the feedback!

I read somewhere top mount is more reliable because of something to do with the oil not having to travel so far. Not sure how true that is. The cams were more for sound. What makes running on 93 a threat on reliability? Sorry for the questions.

don’t get me wrong I love that whine just figured turbos would win easily top end. I use to dream of A kenne bell sitting on top. What supercharger you think? Is kenne bell still a good option?

Whipple are excellent. You can do the whine mod too, to make it whine like a mofo.

Can't speak of Kenne Bell, everyone seems to like the Whipples nowdays.

Basically this.

Detonation is an issue as you increase power/boost. ECU can lower timing up to a point, but your are loosing power and it is just safer with higher than 93 octane rating. Plus if you get bad gas then will increase risk factors. And you live in Miami heat is a major issue!

If you go with hellion the Sleeper kits oiling system is pretty awesome. Gear driven so you don't have an electric pump whining and no worry of the electric pump failing. It has a belt that could fail but it spins pretty slow and doesn't take much wear. Personally I threw a new belt on mine after about 20k miles but it still looked pretty good, little minor cracking. I only did it because I was about to have shoulder surgery and didn't want it to crap out when I wasn't able to fix it.

12:1 compression 800+hp and 93 octane dont mix for reliability. Most guys will tell you keep it under 700 on pump gas which is pretty normal. I run up to 12lb on my hellion kit, never dyno'd it so not sure what it puts down but I run boostane and meth for the added safety on pump gas.

I've got 96k miles on my car with about 50k of that boosted. So they can be reliable but trying to take pump gas too far won't help. As someone said earlier turbos are mote maintenance so if your not doing your own work it could get expensive. Mine were pretty much trouble free after install for about 25k miles or so. Since then I've had a few small leaks pop up. One in the intercooler, two in the oil system and a boost leak. All super easy to fix if you know what you are doing.

I don't think you'll get the sound your thinking from cams on a coyote. Maybe one of the cammed guys can jump in but it's not a pushrod engine.

extremely interesting. I had no idea. Thank you very much for this info!

So basically stay on yo on of it and perform regular maintenance like we should. Not bad! Thanks. I’m going to look at videos coyotes with cams

I was looking into doing the sleeper kit for my gt or an ess centri. I was watching videos online. By algorithm luck a video popped up of an ess kit vs tt sleeper both running the same psi. From the tt pov it shows him winning most runs. A few days later the centri guy posts his video of same race & it was only a win by a small margin. So the cost to tt over the ess kit made the centri a bit more appealing to me. The only reason I'd still go tt sleeper is due to the bov & loudness of the centri. I'd rather keep my car as stock sounding as possible do to the wife also driving it. Now where I stopped was when I seen the same tt guy post up his video braking his opg's. So decided to do my opg/cs first then maybe next year go for boost.

.....be able consistently run top end with the likes of say McLaren 720s...

Not sure if you're serious or not, but even if you do a bunch of suspension/wheel/tire and other supporting mods that ruin the car's daily drivability, this is a fantasy.

You cannot defeat physics. You can't turn a $30K rental platform into a 720s killer.
