Power mods for the I-5
 

I've been thinking about ways to improve power on a vehicle, and it seems to boil down to air intake, exhaust output, efficiency of burn, internal friction, and aerodynamics. Decals alone add 20 hp, but that's for another thread :D

Most performance mods try to achieve more power by getting more air and fuel into the combustion chamber. I'm thinking about hi-flow filters, mandrel bent air intakes, superchargers, turbos, throttle body spacers, aftermarket fuel injectors and such.

What have you tried that works? And what do think is a bunch of crap?

Re: Power mods for the I-5
 

I think most of it is crap.

A Supercharger or Turbo, won't be much help to an inline 5 that is maxed anyway. Hell only GM could get another 20 hp out of it! :D

You'll just start breaking sh1t;)

My bs way of saying....I have no f'ing idea:confused:

Re: Power mods for the I-5
 

Yeah, there's a lot of crap out there. I've seen people mod their MAF sensor, PCV valve, throttle body valves, or install home-built s/c's (inline fans), fuel line magnets, modded (out-of-spec) sensors, grounded capacitor plug wires, and lots more wacky stuff.

I'm hoping for some serious input on chipping and airflow mods that could add a little oomph without starting a fire or killing the engine.

You know, like maybe an army surplus rocket motor to mount on the back ;)

Talk to pedro at south of the border. He has his own rocket city!:cool:

I don't know if anyone else has seen or heard of this.. but I just had a customer of mine show me what he had done to his f-350 power-stroke diesel.

Let me start off by saying this guy is crazy.... Anyway, in addition to his power chip (which gave him about 150 more HP), he is running Hydrogen into his air intake. It looked like a freakin' science lab under his hood!

The system was really kind of basic. All he has to do is put water in the system, it then uses some sort of 'crystals' and electricity from the battery to seperate the Hydrogen from the Oxygen in H20, and the hydrogen travels through a tube straight into the air intake. The Hydrogen then combusts with the fuel, adding 20-30% HP.

I pretty much told him he was full of it, and there's no way it's actually doing what he's claiming. He then proceeded to disconnect the 'Hydrogen' hose, and wrapped a zip-lock baggie around it. He turned on his truck, and sure enough the baggie started puffing up w/ cloudy white gas. He then zipped the bag up, set it on the ground, and took a lighter to it.... Sure enough, it blew loud enough to set my car alarm off!

He said they're available for cars too, for about $800... I can't remember the website though.

Also recommend: 3 Layer FIA and SFI certified fire suit, gloves and balaclava. Along with a full in ride fire extinguishing system, ejection seat, and a good lawyer. :p

Uh, dude ... remember the part about not starting a fire? :eek:

Dey aint no frikkin way I runnin no fizzin hydogin in my injun. No frikkin way!

Re: Power mods for the I-5
 

Nothing proven to make much of a difference so far.

Try a JATO Pack. They add alot of bang for the buck. ;) :D

Re: Power mods for the I-5
 

Now that's more like it :cool:

Re: Power mods for the I-5
 

It's called electrolysis, and there is no way he is producing enough hydrogen to make a difference unless he has a nuclear reactor in the bed of the truck.

Most aftermarket power boosters are garbage with dyno results which aren't corrected for temperature and pressure, and aren't controlled for variables.

hey sorry to revive this thread but i was kinds curious.

Can someone with the proper technical knowhow tell me if the h3's engine and trans, the whole powertrain can handle the addition of a supercharger. Is stuff gona break or explode for sure or most likely not?

Im just curious because i was reading the h3t concept specs and it had a supercharged I5. So im thinking maybe they thought about people wanting to supercharge the I5 and made the whole system tough enough.

What do you think?

Thanks!:)

Re: Power mods for the I-5
 

The best and only way to improve the acceleration and mpg is to hook the H3 to the back of an H2, put the H3 in nuetral, and relax. It works great.


Some have had issues with the K&N kits, some dealers have stated it will ruin the MAF sensor and void warranty, others have had good luck, B&B exhaust will help very little also. Other than that, there's not much out there to really make a huge difference. SC's and Turbos will give you issues and cause more issues off road.

This truck will never be like your Z was.:rolleyes: But it will crawl like a mult when you shift into 4LO.

Re: Power mods for the I-5
 

well i doubt that will really help much, since the h2's spedo shows only 10mph more, and its 0-60 rating is 1 second faster, correction .6 of a second faster. But anyway i am not concerned with speed or power or anything like that.

I was just being curious if anyone knows how tough the I5 is and if it was the same one that was since the initial planning, from when it was a concept vehicle, or if it was heavily modifed to fit production costs? The concept one on the h3t is with a supercharger.

If anyone knows from experience or technical specs, would stuff break on the h3 definately or not?

Thanks for your responses!:)

ahhh come on michael j Fox had the Mr. Fusion in the deloren... how about ptting your old garbage in the airbox to enrigh the flow with meth

Re: Power mods for the I-5
 

Like I said...GM got 20 more HP. Then they ditched it.....no mas Vortec 3500:D

No sense in getting the nitty gritty, it's not worth the time.
