Just ran a Dyno on my long tubes:

Before:
Stock with electric fan/160 thermo/cobra water pump
345hp/417tq

after:
added intake and long tubes with full exhaust (kooks stainless&single muffler)
358hp/425tq

I also had a 365 pull, but the 358 looked like a better curve.


So intake/exhaust=13-20hp and 8-10tq

Anyone know what just an intake gets?

PS: I think that's about as much as you can do to the engine without voiding the warranty.

 

Pretty much proves they are useless on a "stock" boost pressure truck. Go ahead a chip/pulley that bad boy. With those mods you'll get 40+rwhp EASY.

 

I'll second that . The L.T.'s should be one of the last things to add.I do believe the open intake is worth 6-8 H.P. That leaves about the same for the headers..BUT , their true potential will shine After your chip and pulley, just like cornercarver mentioned.Don't forget your boost is down now due to the headers. Get a pulley and chip and your smile will grow.I have a couple of pulleys lying around .Drop me an E-mail if interested.

 

I've got everything sitting here, but since I know the guys at the dyno I figured why the heck not.

Chip/Pully will go on tonight/tomorrow.

Coldie,

How does it sound? Is it any louder than stock with the single muffler, and what kind of muffler did you use?

A chip and pulley will bump those numbers up a good bit. Put them ON!!

Mondo what years are the pulleys for???

 

Is VERY nice. Not to loud, but very deep and rumbling, and WOT is a beautiful symphony!

(sounds like every other supercharged V-8 with long tubes)

Ford area rep listed the hole cut in the bottom of my air box and the Borla cat back as reasons for voiding my powertrain warranty.

 

Talk about getting your panties in a bunch. Cat-back would be easy to fight in court.

I'm not really concerned about my warranty, just was an interesting note (in fact the chip went on last night)

Coldie,
what's happenin today, are you at work? I just installed the 5# pulley........holy *****!!!!!
call or e-mail me about sunday,...JR

 

I'm already planning on upgrading the the 4# pully.

Sunday is still a maybe.. I'm getting the ladies permission

Coldie

 

I agree. It would be easy to find an affordable expert to testify that the engine failure could not have been related to the two mods listed.

Defending any boost-type mods or a chip, however, would be a much tougher fight. Detonation, even inaudible detonation, will kill an engine quickly. Even your own expert would have to concede that point. The burden of proof would be on you, as the plaintiff. However, Ford would have to pay someone to come to court (or arbitration) in YOUR hometown and present evidence to the contrary. If someone were to file a complaint in a close case, I suspect that Ford would just cave at that point.

 

Koldie,


did you order from kooks direct or did you have to go through the MIDDLE MAN ?


Thank you!
