Outside of a few high performance GM and Mopar products no other OEM uses them anymore. On the other hand, almost all OEMs have several turbo options on the lot. I'm betting the reason GM has stuck with the supercharger is the Corvette engine bay. It's pretty cramped in so routing the extra plumbing would be a problem. The supercharger only requires a function bump on the hood.

The supercharger will continue on in the aftermarket because it can be a lot easier retrofit, which is appealing. On the OEM side they are in their waining moments. The turbo does everything better with the only drawback being underhood layout. The OEMs are able to deal with that if it's planned for it the original design.

turbos make the most power with the most efficiently..no doubt.

I just wonder if ford is ready to spend the money for engineering, long term testing, emissions for a turbo v-8 for such a small production run.

a twin screw, 90 deg crank, 5.2 would easily make 700hp and the parts are already available.

if i was putting money on it, i think it will be a blower cars.

yes the foreign cars have gone turbo , but i wonder if they are built for the long haul like ford is? My brother just got a bmw x5 m and all the bmw guys are telling him, fast vehicle, keep it 3 years and get rid of it before warranty runs out. it is fast!

BMWs are junk. They are extremely high strung, temperamental turds that leak oil from every possible location and if they aren't leaking it fast enough they will overheat and make more holes to leak from.

The nice thing about a modern turbo is you aren't adding stress to the motor. The wasted exhaust gas is doing all the work. A belt driven supercharger adds a lot of load to the front of the crank.

Ford said the original Coyote was designed to be boosted and support DI. They just never said how. I would expect the GT500 to have some type of stroked Coyote with forced induction. I highly doubt it will keep the Voodoo crank.

I don't see ford going back to a supercharger anytime soon. They currently have 6 different sized ecoboost engines with 4 of them having two different versions for specific vehicle applications. Why not apply all that knowledge into a turbo'd coyote of some displacement.

o5redfx4, dave switched to procharger, got tired of rebuilding no2 motors. also went to a, i think a 525 ci motor over the old 632. other classes reqiure blower cars to be limits to ,i think, 525. alot of the guys do racing outside of street outlaws. youtube it.


fords been toying with us on a turbo v-8 since late 80's. i just dont think they will do it.

my next car, depending on my money situation, GTR or awd turbo 911. turbos own the high hp and awd is a must for a car making over 600hp, IMO.

If you want fast and AWD get a RS series Audi. Throw a tune on it and hang on! If you go the 911 route don't go with the AWD version. They launch insanely hard because of the engine hanging way off the back. The AWD in that car kills it.

For the GT500, a supercharger is the easy way out but I wouldn't be surprised if there's a pair of snails hanging on the side of the engine. Ford has been throwing them on everything now so their power train guys are getting pretty comfortable with designing for them. The turbo route will also help them get better test results for CAFE numbers. That's always a good thing for the OEMs.

That could be the one that was caught testing at milan dragway, reportedly it ran 10.98 in testing.

Jaguar / Land Rover has a supercharged V6 (built on a 5.0 block but with 6 cylinders) as well as the Supercharged 5.0 V8

IIRC in 2014/2015 LandRover only offered the SC V6 or V8 as their only engine options for all the bigger SUVs



Currently their only other engines are EB 2.0L and the 3.0L Diesel

How are they going to up the displacement that much on a modular block? From what I remember reading opening the last generation to 5.8 was pushing the limits, unless they make it a V10 there's not enough room between the cylinders to increase the bore that much. They could up the stroke but that would impact the upper rev limit which isn't desirable in a sports car. I'm thinking this is another rumor started by a car rag to boost their numbers.

The Demon, it will make a lot of power but still weigh more than a battleship and suffer for it. I just can't​ get excited about anything Mopar made since 1972.

I did forget about the Tata brands that still use superchargers. Will the next generation of cars keep this engine or are they going another route?

There is a stroker crank out there for a 5.4 and if you sleeve the block you can get a 3.75 bore out of it combined with the crank you can get a 390 c.i. or 6.4L. The only way to squeeze 7.0L out of a modular is to add more cylinders. Either that or create an entirely new engine, but I don't see Ford spending that kinda coin for a one off engine with a limited production, unless they plan on a lower hp high tq mass production version for the trucks.

Maybe the 6.2 Boss can be punched out to 7.0?

Possibly, it does have a much wider bore spacing. However, the heavy iron block and 2V SOHC heads don't lend themselves to a sports car that's already a little bit chubby. I'm not seeing Ford making a giant V8 for a limited run of sports cars. They wouldn't do it for the GT so I don't expect it for the GT500.

I would much rather see ford use the 5.8 out of the 13-14 gt500, strip off the S/C, bump it up to 11-11.5 compression and adapt it to accept coyote heads. They could tune it for 475-500 hp and drop it in a mustang. They could even call it the BOSS 351. And they can use the same setup with a turbo or S/C for the new GT500 and a lower compression version for the trucks.

Imagine, a 5.8 or 351 with direct injected coyote heads and about 450 hp and 500 tq in a regular cab 2wd aluminum bodied F150? Can you say gen 3 lightning?
