'06 Real Power Improvement

[stagger_lee]

Points well taken Tomp. I am coming from driving pre 75 rigs FJ40s, Scouts and CJs with 5.0+ gears, 3 and 4 speeds and big motors. 55mph max on the highway at 4200rpms was common. Anything beyond that is luxury for me, so I could care less. Ability to travel at 65+ mph and get gas mileage better than 8mpg? Stoked! .

Trade it for a euro $50K SUV that burns premium only and gets 16mpg for ability to win the pink slips on the elements you been racing...

I went from the 06 to 07 and there is a little improvement but not enough to get excited about. The heat issue I am still waiting on but it's been 100+ at 5,500 ft so any vehicle has a tough time with the thin air.

Only the V8 will cure the need for power. Regarding the 3.5 to 3.7 difference, it sounds like most are saying the difference is small.

it is small. but the v-8 seems like overkill. i will buy a H2 if i want a v-8.
the I-5 has character and I love watching faces when I say "it's a 5 banger"

H2 is too big for wheelin in the city, burbs, or woods for me. H3 is the right size for those with small families. H3 handling is nimble enough to be fun.

I just drove back from Moab last week. 350 miles, 5+ miles over the speed limit the whole way except for Vail and Loveland passes. They slowed me down but I still passed plenty of cars. It helps to have a 5-speed ... just put it in 3rd.

I don't believe in snake oil for more HP. You might get some oomph from exhaust headers and a good cat-back, or even a PCM tune (according to some). But not much bang for the buck, imo.

Your truck is what it is ... accept it. What did you expect from a brick-shaped SUV with high ground clearance and a 5-cyl engine?

Tried and true tips:

Reduce parasitic losses (friction and wind resistance) - synthetic engine oil, street tires, correct tire pressure, minimum exterior accessories

Reduce weight - minimum cargo and accessories

Do regular maintenance - replace air filter, change oil on time (engine, transmission, transfer, diffs), all other maintenance on schedule

Mods harmful to performance:

Airflow modifiers like the "tornado", homemade or ebay "turbos", generic brand or homemade intake pipes

Mods harmful to engine:

Oil additives, fuel additives (except injector cleaners), oiled air filters (allow more dirt and may damage MAF if overoiled)

Questionable mods (your results may vary):

Throttle body spacers, PCM re-program, electric engine fan, exhaust headers and cat-back (if tested and tuned for power instead of sound on the 3.5 or 3.7L application).

I don't think you have driven an H2 enough. With proper Pilot it is very nimble. You mean H1

i took a family on hells a couple weeks ago . and when they asked what was under the hood , i said a little 3.5L 5 cyl. tractor motor they were amazed . didant even know that there were 5 cyl. engines

This is America and there's no such thing as an automotive overkill!

I have an 07' and did CAI and throttle body. Big diff! And I live in TEXAS where the daily average is 100 and 100% humidity! The air down here in the Gulf Coast region is like sucking a sauna thru your intake.

Sorry to say, I'm pretty disappointed with the 5.3L alpha power. Really was expecting more. I'm sure that you can get a lot more power from one though with the normal, cold air intake, exhaust and a tune mods. I really think the 3.7 is a pretty good improvement over the 3.5 especially in the lower end. I mean 20hp is almost 10%.

I don't see why people don't think the PCM reflash works. I personally tune vehicles and have had great success in the drivability on the H3, especially if larger tires are installed. Unfortunately I don't have any dyno numbers since I don't have a dyno, but everyone I've tuned says "Everyone should do this."

Yea we've heard that before (on various infocommercials here), especially the part about not having dyno numbers.
