if you are worried about weight onthe front end.... Rear mounted turbo setup... done.... all weight in back on rear wheels..

Zoldier

I think weight in general is the concern. An STS turbo setup will probably heavier than a standard kit because of the extra tubing you have to run to the rear of the car.

I'm one for more power also but on this car I think NA is the way to go. I ran my 350Z NA and still ran faster times than guys in GT500s. My last dyno was 282 whp.

I plan on getting an 03-04 Cobra for my power car.

Whammer

Yes, but HOW LONG will the motor hold up? It's not a matter of what kind of power you can get out of it for a test, it's a question of durability.

I'm sure some folks with look to boost HP on the Boss but I'm on side with those who say leave it as is. I can see doing a tune to improve throttle response but I wouldn't go beyond that.

Nccstud

Exactly this. You can get a ton of power out of this engine, and maybe it lasts you a couple years. But if you're throwing 800hp down, the lifetime of that engine has got to drop some unless you do more work to it.

On the flip side of that, if you're looking to get insane amounts of power out of an engine and don't need the engine to run perfect for the next 50 years. There is no reason you shouldn't try it and make an insane drag car. To each his own!

There's a whole lotta daylight between 400 and 800 RWHP. The Boss will be seen at drag strips.

Everett

Good call. And it's the connecting rod that's the weakest link in the rotating assembly isn't it

Everett

A boosted coyote engine would need a lower cr to still be able to run pump gas. Sure the potential of these motors is unreal but availability of fuel would be the issue. What's the max cr you can have and still run 93 octane

Leo93

Hmm not sure. I guess that's the next test

cdynaco

Plus you still have many areas where 91 is max pump gas.

Everett

Well we can get 94 from only 1 brand of station here and it's ethanol polluted. That coyote is an engineering marvel

siggyfreud

The only thing that Ethanol is hurting is the MPG (slightly). Otherwise, it has a higher octane rating than gasoline, so it should help prevent detonation.

Everett

Sure it's higher octane but ethanol has less energy than gasoline. And the mpgs are hurt more than slightly,and what about the water ethanol absorbs. Ethanol is great as anti-freeze tho,but keep it out of my gas tank

I vote forced induction. Positive displacement type. Twin screw for road racing. I seriously doubt if is gonna weigh 200 lbs either. Maybe 100 total for the setup. A few little suspension tricks and it should kill a stock boss. The GT500 is no way a road racer. Suspension and torque curve is what you need to be concerned with. Max power and traction at the rpms that you need them. Fuel requirements depend on boost levels and tuning. A good dyno tuner can work all those issues out. Subframe connectors will do wonders also.

AlsCobra

Also. My tuner is an authorized roush dealer. If you go with their kit from an authorized dealer, you still maintain factory warranty. Just my two cents.

Everett

I read all these threads about guys and how many hp they got. How much of it is useful,there when you need it. A twin screw builds gobs of torque and more street friendly,boost is built very quickly.

AlsCobra

Yep. And my hp curve is a straight line. I'm making over 550hp from 2500-6500. That's what is needed for a road racer. Constant hp through the rpm range. Twin screw all day long.

ShaneM

id go centri. and the tranny will go before the internals me thinks. That is the problem with the turbo kits, the torque is so high. i think a vortech or procharger on a boss would rock. there are plenty of passes on the 5.0 now, they are plenty robust. i'd like to see someone dig as much na power out of the car then go blown.

Mustang_Man

You're making 1150 ft-lb of torque at 2500 RPM?

AlsCobra

What? No man. A little over 550. 2500-6500 rpm. Flatline torque curve. Basically just saying that coming out of a curve at 2500, the hp is already there. Not having to wait on peak hp.

siggyfreud

Not sure why thats a bad thing for the gas tank? I'm not arguing with you about energy loss, but aside from that I'm not seeing the negative.
