At least he is consistent!!!

 

Maybe i am misinformed, but I was under the impression that a turbo recycles some of the energy (exhaust pressure) already spent by your motor to create boost which effectively raises the volumetric efficiency of the motor which would get you further per gallon than the same motor with a supercharger. The way i understand it is a supercharger takes some energy from the motor (parasitic drag) to spin it in order to create boost and while it is able to return significantly more power to the motor it is not neccesarily better from an efficiency point of view.

I agree that it is not neccesarily an issue if you are looking at it from a performance standpoint, and I wasn't trying to fool anybody.

Given the choice with money not being an issue I would go with a supercharger because it is just what a musclecar should have. unfortunately gas is soon going to be $5 a gallon, and while I would love a nice whipple under the hood I think it would be smarter to go turbo and pick up some mpg. I have heard of turbo mustangs getting close to 30 mpg. Is that true? if neither one is more efficient than the other then I am misinformed. please let me know if I am mistaken because I am going to go FI in the near future and while my heart says S/C my brain says Turbo.

 

I seriously hope it doesnt go to 5 bucks. Gas is mid 3's where I'm at and the economy is falling apart partly because of it. Hate to see what happens around here if it goes to 5.

 

It will definately get to $5.00 per gallon and I am sure that future is not far off. I bet it will be $4.00 by mid to late july. OPEC is not going to do us any favors anymore.

 

And if you're driving a Mustang and concerned with gas mileage I suggest you go buy a Prius and let some deserving less concerned person have your TOY. Gas could be $6 a gallon and I'd still drive my car... life is too short to be worried about a few $.

 

Okay...now lets throw something else in the mix...what about the Hellion Turbo system....I know John, so I think I could work with him on the tuning pretty easily...but does anyone on here have any experience with his kit.....
Thanks.

 

Agree with that. Who knows what the gas will be like In ten years. May not have enough octane to run our current engines as they are configured. The world is going "green" and we may be caught in the tidal wave of environmental policies. At least mine is paid for so I can make a nice planter ouf it.

 

I drive my stang hard, and I drive it every single day rain or shine unlike some people who would not dare remove the car cover or open their garage at even the slightest hint of rain. I didn't buy it for the superior gas milage either. F a Prius and you for your little prius suggestion

I think a Turbo setup if it lets me save a little cash while making the same power as a supercharger is simply a more intelligient decision it is simple MATH.

by the way since you are such a baller why not buy me a supercharger....it would be a good deed. don't worry...you'll make more....

 

I don't think I'd say the choice of a turbo would be more intelligent. I'm not taking sides here, but I have 2 turbo vehicles, and my Whippled '05 has what they don't....instant off idle torque and gas prices don't really matter too much at all where my stang is concerned since I only drive it on weekends.

 

see this is where I am a little confused. I have been told by a couple turbo tuners that if you match the right turbo with the motor you can make big torque down low. if this is wrong I would much rather go with the whipple since torque is what I am after. I just figure if you can get the same performance with improved milage it is just icing on the cake. best of both worlds seems the smarter choice imho. but if that is not true then that is one more checkmark for the S/C and it wins out. do your turbo cars do better on gas than the s/c car does? milage is not a dealbreaker for me (if it was I would not have a musclecar) but if it comes with the package then even better.

 

Turbos have come a long way in the past few years when it comes to lag. One thing to keep in mind is turbos will always have some lag because they need exhaust pressure to make them spin which takes some time. I mean the exhaust gasses don't travel at the speed of light and even if they did it would still take some time to spool up. Don't get me wrong here, turbos are the most efficient, that's a fact, not an opinion. I just want the instant boost in my car because it's my preference.

I have an '08 twin turbo power stroke in my driveway. They designed this engine with twins to cure the terrible lag problem of the past from one larger turbo which takes time to spool up. The idea is to have 2 smaller turbos...one for out of the hole bottom power and then the 2nd one as stage 2 of the boost all with the idea that the smaller turbos will spool faster. I can say from experience that they do spool up faster than my 2000 single turbo truck, but there is still substantial lag. Keep in mind that aftermarket turbo systems that are designed correctly will further reduce the lag, but will still have some lag for the reasons I stated in the first paragraph.....the exhaust has to travel and the turbo has to spool.

If you had an engine that actually produced some real torque on it's own (n/a) which Ford modulars do not, then you'd have an animal of an engine with a turbo for a power adder when it comes to bottom end power. All this said, the fastest 3 valve stangs in the world will be turbo cars as they start hitting 8 second territory very soon. The supercharged cars won't be able to consistantly compete. Turbos make more peak power and torque.....just mainly mid and top end.

Anytime your power adder needs to spool up for real power you'll get better mileage whether it's a turbo or a centrifugal blower.

 

right on. I guess i am just going to need a blower then. my new vanity plate is FKOPEC

 

Well, if you like that instant big block like torque get a twin screw for sure. It will feel like a big block and rev like a small block. The best of both worlds.

 

Suggestions like yours perplex me. So if he said he was looking for springs, shocks, etc. because he wanted better handling, would you tell him to get a Lotus Elise and let some deserving less concerned person have his TOY? No you'd probably offer realistic reccomendations.

I drive my car every day and LOVE it but if there was a way to make it more powerfull and operate more efficiently I'd be all over it!

 

This is an important point---do some research on the tuners in your area---that may make the choice easier for you.

Here is a good video of what the whipple sounds like. I was racing another import car, but basically you can only hear my car--so it makes a good video for showing what the whipple sounds like:

Whipple mustang 6.89 @ 100 mph Irwindale

And I would like to add--you get great power from a turbo---but you can also from a twinscrew---I run 10's in the 1/4 and 6.8X's in the 1/8th and I daily drive mine all the time. I put almost 600 miles on the car last week and love driving it on the street.

 

what did it cost you to forge the bottom end if you don't mind my asking? did you do the work yourself?

 

If you want instantanious torque then you will want a supercharger. BUT...I would suggest driving both a turbo, and a supercharged Mustang before you make any decision. They are 2 totally different animals. If you are traction limited in 1'st gear...the boost will be there as soon as you need it anyway, with either one. They are just completely different driving experiences. I do like being able to "turn off the boost" when it's not needed. But in essence it will come down to a personal preference as to what YOU want. Hope this helps, John.

 

That's a good point about the loss of traction, but when you come out of a curve in the road in 5th gear taching around 2000 rpm's and you give the hammer a push the Whipple pulls real nice.1st gear traction sucks with any turbo or blower....even 2nd gear sucks when it comes to traction. Drag radials help that problem, but good drag radials really suck in the rain. It's like you're on ice with the Mickeys, but they are the best for dry traction. It's also a good idea to drive a turbo and blown car if you can swing it.

 

This is a great discussion.... When I get some cash I'll be making this decision too.... Dang you guys I'm supposed to be studying and I just read this whole thing! haha



By the way that whipple whine is just amazing I had no idea they were that loud.

 

I haven't gotten mine built yet, but they can run a wide range of prices. I'm emailed a couple places on how much a built shortblock would run. You're talking maybe 4-5 grand plus the cost of a shop to install it. so maybe 6-7?
