Next round of mods, need blower guys help.

Twin charging for a lot of reasons is silly. If you want to go big go with a big single and tear the SC off the car.

Thanks Kevin, no thanks Brian.

Noted.

Twin charging for a lot of reasons is silly. If you want to go big go with a big single and tear the SC off the car.

Really...please explain how silly it is? As for a big single as an alternative....as long as you're alright with giving up a lot of drivability and shortening your power band as a trade off for high horsepower, then by all means, go right ahead. I'll take the street manners and power curve over a compound set up over the boost lag and spiky power band of a big turbo any day of the week.

 

[CobraRed_96_GT]

Just keep the intake temps low for those stock pistons please (not that they're weak, it's just a good idea to not even come close to detonation)

 

[4tun8]

Ok I'll give you a list of reasons why you should pick either SC or Turbo.

1) overly complex
2) lots of high spinning components
3) more heat is created
4) 1000+ HP doesn't have street manners, stop fooling yourself.
5) More complex tuning


I could keep going if you'd like.

Also, is the FPDM the pump drivers? What is the upgrade?

Kevin, I have the big Sniper Bazooka MAF meter. Its supposed to support like 700 or 800 hp so do I still need the Mafia?

Yes. The FPDM stands for "Fue Pump Driver Module". The upgrade is to just get another one to add to your system. (I bought another one for $40 shipped off SVTP and made my own wiring harness using pigtails I bought from Tousley Ford)

It is a much better set up than a modified FPDM because it lowers your Fuel Pump Duty Cycle. It gives each GT Pump it's own FPDM. (Just like the factory did on the Ford GT and new Shelby GT500's.) I have the wiring diagrams and everything when you are ready.

I can also help you source the parts for the system and save you a few hundred dollars.

If you already have the Sniper MAF then you should be OK and not need the MAFIa. (I forgot you had that already)

 

[Gearbanger 101]

1) overly complex

I guess that depends on your interpretation of "overly complex". One mans complexity is anothers attention to detail. Its certainly got a lot more parts than a stock Cobra blower or Twin Screw swap, but its no more complex than any twin turbo instal.

2) lots of high spinning components

Does that scare you? Two turbo's and a blower? FYI, when combined all in one system, the blower and turbo RPM is actually lower than they would be if installed as single power adders on their own. That's the entire point of the system. You don't have to spin each power adder drastically in order to move airflow and presurize the system.

3) more heat is created

I'll assume you're talking about discharge tempuratures? If so....you consider 120-deg discharge temps on back to back runs and an average of about 100-110-deg a lot of heat? And that's with the system pullied and spun making 1,188 rwhp and 1,015rwtq. You can bet discharge temps would be lower as blower and turbo RMP are slower. Hell, I'm putting out 170-deg with my overspun Eaton M90S and I'm not hardly making 1/3 the power!

4) 1000+ HP doesn't have street manners, stop fooling yourself.

First off, I stated that the kit was over 1000hp capable and adjustable for different power levels...not that bolting it on saddles you with 1000hp right off the bat.

Either way, why is it that you can't believe 1000hp can't have street manners...is it because you refuse to aknowledge as much?

What exactly do you define as street manners? The compound kit has as good a street manners as a hard spun twin screw and much, much better street manners than a large single turbo. What about instant and controlable torque production, a smooth linear power curve

Here's a dyno graph for your average modified '03-'04 Eaton Cobra...

The engine was equipped with an Accufab throttle body and inlet, XE264AH Comp Cams cam and Flowtech long-tube headers and pullied for about 12psi.

Now here's the dyno graph for a nearly 1,200hp Compound Cobra...

Don't see any power spikes, or lag in the power band at all, do you? And those dips you see every once and a while....that's where the rear wheels broke loose on the dyno.

Bad ass....sure, unstreetable...not at all. You can wreck a 500hp Cobra as easy as you can a 1,000hp Cobra. If you're not smart enough to control your urge to drive it with your foot in the oil pan all the time, then you probably shouldn't be behind the wheel in the first place.

5) More complex tuning

And...what's your point? Do you plan on doing your own tuning? I'll leave that up to the shop running the dyno personally. If it costs me another hour or so worth of dyno time for that kind of power, I'd gladly pay it!

I could keep going if you'd like.

You sure about that?

Do yourself a favor and read over the The Manhattan Project article from Muscle Mustang & Fast Fords before you pass judgement and dismiss the set up.

Compound Boost 2003 Mustang Cobra Twin-Turbo - Muscle Mustangs & Fast Fords Magazine

Or check out the article from the April 2009 Hot Rod Magazine with the kit on both an '03 Cobra and GT500.

Hows 1032hp/976lbs ft on 91-octane pump gas!!!

Thanks Kevin, big help!

As soon as I have the house sold I will be ordering the parts. I can do all the intall on everything and then I guess I will order the bigger software pack for my tuner and bring it down to that place you like and have her tuned
Guess I will hold off on the meth injection. I was always wishy washy on it but my father was so hyped up about them that I figured I would get one to shut him up
But if its good for 20 or more horses then I may still get it as they are cheap.

If I get over 600 rwhp though I will be very happy. Can I get one of thoes fancy badges like you have when I do it?

The power the car has now is excellent but I would like to just be planted in the seat when @ WOT in the higher gears too. I think another 150 or so horses over what I have should fill the bill

I will be doing the head cooling mod at the same time and already have the bigger heat exchanger and rad so I should be ok in the heat department. Also the Twin drops the IAT over the heaton so thats another plus

 

[LaserSVT]

Brian, enough about the compound boost! Yes its neat, yes it makes big power. Its just not what I want. Since I want way less power then what it can do I dont see a reason for all the added complexity, parts and weight on the car. If I can get my power goal by simply swapping on a twin screw then thats the best option for me.

 

[02nightmaregt]

Laser dude that sounds like a very streetable build. You'll be able to sit in stop-go traffic in 90 degree heat with the ac on and the temp needle probably won't move. I didn't know you had a bigger radiator. Plus with the head cooling mod that thing is gonna run nicely! Good Luck.

LOL... You won't have any trouble getting 600 RWHP. It's MUCH different than the Eaton. It pulls much harder and doesn't drop off. 3rd gear with the TS pulls like the Eaton in 2nd.

Let me know when you are ready and I will get you a list put together of what you will need and where to source all the parts.

I can even help you if you have any trouble or questions with the install.

I am with you Bill. Even if someone gave me a TT kit for "FREE", I still wouldn't put it on my car.

 

[CobraRed_96_GT]

Compound boost is Banger's new TorkTech - not that he was wrong about torktech though

 

[SaleenGT2001]

i want a TT kit!

 

[ErikTheBeast]

you def. need 60 lb injectors if not more...you could go with twin gt pumps and be set for well over 1000 hp....be careful w/ pushing 600 hp though...my buddy's 03 cobra had a 2.3 whipple on it and was pushing 590 and blew a hole through his block....he was also tuned by james from RWTD so you know the tune was good...i'm pretty sure your stock rails are good... again my buddy's 03 had stock rails stock pumps w/ 60s and kb bap...his fuel was close to tapping out but not quite...good luck!!!! should be a beast when all said and done

My buddy has an 03 w/ about the same stuff your friend has and was making 650 and the crank broke at the snout. At least he's going TT now. Good luck Laser

 

[SaleenGT2001]

a broken cobra crank?!?!?!?

 

[ErikTheBeast]

a broken cobra crank?!?!?!?

Yeah , talk about a weird occurrence. Although to be fair , it did happen when he had slicks on and im sure he was out launching the sweet jeebus out of it.

 

[Gearbanger 101]

Brian, enough about the compound boost!

That wasn't for your benefit. I was defending my point to another member who chose to continue the debate. Either way, I don’t see why are you complaining? I figured you would be ecstatic that one of your threads has any Tech Talk what so ever in it.

Compound boost is Banger's new TorkTech - not that he was wrong about torktech though

I'd combine the two of them on a 2V if I could afford it.

And I’ve been for the idea for quite a while now. If I end up keeping my engine and blower after I sell my Cougar, I might just piece together some sort of single turbo compound kit with my existing Allen.

 

[04sleeper]

a broken cobra crank?!?!?!?

I have seen several broken Cobra cranks.

Every one of them had an aftermarket lower pulley. The aftermarket lower pulley's do not have a "Cage" support like the factory to help the strain put on by the blower.

The factory pulley's also have rubber bushings in the middle of where it attaches to the hub to help with harmonics. The aftermarket ones do not.

is there not a "good" one out there?

Ahhhh. That was gonna be my next question cause i was there that night the dude with the yellow Cobra broke his So I can spool it to 18-19 without changing the crank pully? That would be cool. At the time I do all this I also want to get nice blue/silver idler pullies and the blue valve covers with the FRPP COP covers like EPIK has on his car. I also wana do the aluminum expansion tank and power steering tank. If I could find a brushed cover for the fuse box and have an intake pipe that would fit under the strut tower brace and fit with the Steeda box then my engine compartment would be exactly how I want it.

So Kevin, ya wana come down and help with the blower and valve cover install when I get it all? Ill by your favorite beer.

 

[LaserSVT]

Okay Kevin, can you give me a list and prices as well as where to get the blower/pumps/hat/injectors/lines/drivers etc etc. Thanks mang!
