Hey there everyone...

I've got a 02 F250 with the V-10 and would like to increase the HP if possible. I have a couple of questions...

1) Can I use a OBD unit to increase the HP of the stock chip? I saw somewhere that the mfgs deliver the trucks with a lower HP to satisfy the greenies. It stated that you could put a writer on there and bump the value from greenie to meanie.

2) Besides sounding bad ***, how much HP would a aftermarket exhaust system give?

Thanks,
Mike

 

If you do a search this has been done many times on this topic.

I have no answer for the fist question but as for the second the exhaust will give you some HP but you will loose some low end torque. I personlly value torque way more than HP and thats why mine is still factory. It all come down to what you use your truck for and what you want out of it. The HP/Torque ansewer seems to be the concenses when reading about the exhaust.

Good luck and if you chip/program it let us know how it does and what brand you use.

 

Thanks SLE...

I did do a search for Q#1 but all I found was reflashing for problems and updates... didn't see any for increasing HP.

Regarding #2... I was unaware that I would loose torque by changing out the exhaust system. I'm purchasing a 30' trailer and will want the torque for the hills.

Thanks,
Mike

 

Depends how much you want to spend. Any gained HP numbers are subject to varying opinions. Do a search on this site, and you will see what I mean.

Here is a good example and discussion on performance:

That said, here is my 1/50th of a dollar:

Biggest gain for your buck is a Superchips or Diablo performance tuner. Next, look at the K&N FIPK and a Flowmaster exhaust.

I would call those 3 mods the easy pickings -- easy to install, decent gains (30-60HP for all 3, variance is on the RPMs you are turning). The gain is for not too many $ (somewhere around $750 for the 3). Additional gains come from modifying everything in between the FIPK and Flowmaster: new MAF sensor, throttle bottle, headers, Y-Pipe, true dual or H-pipe exhaust, electric fan, fuel injectors and pump. But that gets more-and-more expensive and the HP become harder-and-harder to squeeze out.

If you are really serious about some HP gains, slap a Kenne Bell Supercharger in there instead (a cool $4000 is all).

If that sounds a little pricey get the Gale Banks Power Pack. It is complete exhaust makeover from air intake to headers to Y-Pipe to the exhaust. (That will set you back a modest $1600).

The Flowmaster or Gale Banks exhaust mod will cost you a little torque, but I think you can make most of it up with the Superchips mod. You can specify the Performance Towing setting to shift some power to torque. When not towing, use the Performance setting.

 

Get a Superchip tuner 25-30 hp.I have extensive exhaust mods,but i did not lose any low end trq.I have gobs of low end trq.The corks in the exhaust are the stock manifolds,and the y-pipe.I am usually at odds with folks about exhaust mods.A muffler wont yield much.

 

I have a Granitelli MAFS, BBK 62mm throttle body, cold air intake, Borla headers and y pipe, a Diablo chip, and a flowmaster muffler. I have tons of low end power. She'll jerk your house right off the foundation.

 

camo4stealth: I have the same rig, and I am coveting all your mods, esp. the Borla Headers and Y-pipe. I just don't have the $1000-plus-labor to install the Borla kit. (Plus I am worried about breaking those fragile manifold bolts).

What Flowmaster are you running? With the headers, I would think the 40 would be too loud. But maybe I am getting too old.

 

Ok... I thank you all for your help. I have been educated! That superchips tuner is a great product. However, I am bummed that you can't access all aspects of the computer, i.e. Tire Size. But the ability to gain HP and torque as well as read error codes makes it well worth the price. So, I am definetly going to buy the tuner.

Not so sure about the exhaust though. Please, excuse my ignorance and correct me if I'm wrong... I understand you want both HP and torque, but HP factors more in the speed/throttle response while Torque is for towing power.

Thanks again,
Mike

 

I've done the tuner, exhaust, intake route and the gains are there, but the best bang for the buck is a Cyclone Fan clutch kit. http://www.lightruck.com/other_cyclonefan.asp

Mine came in on wednesday and I installed it yesterday. It made a bigger difference than all the other mods combined. When it's cool. When that fan kicks in it's back to normal.

Oops, I intended that to be a question. Is this quote a correct statement?

Thanks,
Mike

 

etcetera: How much buck for that bang? I don't see any prices anywhere, they just want you to call.

I still say the Superchips is the best bet for mwpierson or anyone looking for their first mod. Very easy to install (essentially plug-n-play), configurable, and a noticable gain. Unlike the fan, it is always on, plus you get a diagnostic tool.

While I am interested in this mod, I am betting that it is the synergy of your other mods working with the 'fan off' that makes Cyclone feel so peppy. There has been a fair amount of debate on the electric fan, and I am skeptical that an electric or Cyclone fan mod alone will give you more HP than a chipped V-10 with a combination of mods for intake, TB, cat-forward and cat-back.

 

Read this Mike: http://www.bankspower.com/test_results_AF05.cfm

No tq loss above 2000rpms. I know when I'm towing, when I need the power to climb hills, I'm turning 3000-4000 + rpms. The Banks or Borla header kits really improve the performance.

 

The cyclone fan kits are $500-600. A tuner is a good first mod because it's "Plug'n'Play". I think the best thing about the tuners is the difference it makes with the tranny. Firms those shifts right up. My headers and modded y-pipe were a worthwhile mod. The intake made the truck louder, it's really hard to say if it actually improved performance. If I thought I could get my money out of it, I'd sell it and go back to stock.

The fan, however, is very noticeable and only comes on when the truck is getting hot. Without the AC on, and with the fan in override mode so it wouldn't come on when the cab interior was warm (IE, it'w presuming I might want the ac on) the fan didn't come on once on my camping trip over the weekend. Pulled a small 3500lb trailer and probably 1500lbs in the bed, 2 friends. Temps were in the 80's on the way out and some pretty long 5 and 6% grades. Tranny temp was barely breaking 160, and apparently the engine didn't get warmer than the preset limit in the fan controller.

Turn that fan on manually and it felt like the brakes were on.

I also got 13 mpg average for the trip. Speeds in the 70's and 80's.

One piece I am missing that is probably important, is a throttle body. I bet that would make the intake worthwhile. Hmm, maybe I'll by myself an accufab for christmas.

Eric

 

Yes the accufab is awesome for performance. I did it myself. 15-30 minute job. Works great.
