PS don't let your dog drink it ............... Moonpie was under them sawhorses fer a week bfor he cum outta dare!

Does that work? All mothballs are not Nathalene. Would Berryman's carb. cleaner work instead of STP?

Berryman would probably eat the plastic bottle, but a glass mayonnaise jar would work.

though dsm speaks some truth i wouldnt say all gains are lost because my i can feel my fit has better response with my added bolt ons(mainly sri and ik22).
Good to know I haven't pissed off everyone here! I appreciate the support but I think Schoat's ire was directed more towards Occam's stance on L15 modding.

And there are points where I agree with both of them actually.

I do actually like NA tuning, and when I get my FIC on thursday I hope to start wiring it in over the weekend. I will be starting my tuning NA as an experiment really, so that should be fun.

Then when I am comfortable with the state of the Laser (which came out of hibernation today! ) I intend to slap the rest of the go fast bits on the GD3!

Ive also seen a stock K20 running 20 pounds of boost in a Acura Integra running 11.6. Its all about the set up and tune.
Not too mention the driver! A friend of mine just picked up a 700rwhp Supra, and the previous owner was running low 13s

You are right exactly though, you need a cam, P&P and some springs to even think about spinning 9k rpm out of the L15!

Berryman's B12 will work too! I think Texas Coyote swears by that stuff as well!

The napthalene balls sublime when left in air, and I know people who would simply pack their air-boxes with them on the inlet side of the filter!

No kidding!

I finally got some of the more annoying quirks on the Laser resolved today... only to find more. My WB O2 sensor was dying and my 19 year old knock sensor finally started dripping goo out the back so they both had to be replaced.

And now that the weather is warm I had to re-do my injector deadtime v. voltage adjustment table, so my global fuel settings had changed. I also forgot that my Stoich ratio was set for E10 gas So I was running .6 pts leaner than I wanted under cruise.

OCD makes tuning painful sometimes. It becomes a war of endurance and attrition.

My Combined FT's are finally zeroed, all the way till I hit the gas and there is a pocket of cells in the tip-in region disagreeing with something and I spike super lean.

So I had what was supposed to be the first cruise of the year cut short when I started seeing the WB head towards 17:1AFRs.

This meant I had to lock it in open loop and throw the fuel sliders 30% lean just to make it home safe.

My turbo oil return line started dripping too, like a copious amount of oil, so I have to see what thats about. But by the time everything else was sorted I had to go and do a tutoring session for an 8th grader and didn't feel like dropping the subframe and distending the other 3 motor mounts.

I have a new 3" SS downpipe coming to replace my old ghetto fab exhaust, and because the car is going to full race mode this year I may just slap a turn down at the end of the downpipe and call it a day

Ive used barryman B12, It works and got 33 mpg in a older van I had. Premium and berryman b12. It had a 3.3 liter motor and with synthetic oil and all highway ran great.

Napthalene has a low octane compared to premium. 92 or so but also has some side effects too. Plugged fuel filters.

Thats another problem with tunes, they are constantly changing. Your fuel trim were running .6 lean with BP? When you start tuning the Fit you should set up a tunning thread and the air is still to cold compared to summer so more fuel is needed.

i was saying more like fast and furious style with "he's got enough NOS in there to blow himself up!"

So, just out of curiosity, replacement parts can I buy that are LIGHTWEIGHT?

Just hypothetically, if I replace as many parts as I could with their lightweight counterparts, I would probably get exactly what I want without adding any horsepower?

Here's what I know of:
Wheels/tired (Definitely doing this)
Pulley? ( I hear people talk about this, what pulley are they talking about)
Flywheel

anything else aside from taking out the back seats? I use my fit entirely for cargo space anyways, rarely eve have more than just me and a passenger in it.

A 35shot can actually put over 70whp extra down in a boosted setup. This will not likely be done on stock pistons/rods though.

I think a lot of people misunderstand NOS systems, and they really get a bad rep from people who have no business using them.

Except for the inconvenience of having to constantly fill the bottle and maintain pressure with a bottle heater.. not to mention the legalities.. NOS is the best $/hp mod for a stock, well anything really.

Just retard timing and let 'er rip.

NOS system? the "system" part is already part of the Abbreviations silly. on a more serious note, why not? he did say "cheap" horse power gain.

Lightweight crank pulley as well as a lightened flywheel and a pucked clutch are going to be the most dramatic in terms of performance gained from weight loss items.

The rest will be bafflingly expensive.. lexan windows, CF doors, CF hatch, CF hood, CF roof.

Lightweight front seats, removed back seats.. any unnecessary plastic bits.

You don't want to tin-can the Fit too much or you will likely regret commuting in it.

Hold on I have to go to the ATM machine and use my PIN number.. feeling pedantic tonight are we

I would say go for it but he has no control over timing/fueling to accomodate the N2O

Enjoy your +200k rep for making me actually LOL

People do that all the time... PIN number, ATM machine, etc etc.

as DSM said, flywheel, pucked clutch and pulleys will give you the best gains! as for pulleys, don't go underdrive or you'll screw up your electrical system... wheels and tires will also give you good gains!

CF parts are part of sprung non-rotating mass... so these won't give high results...

When you are talking about a cheap gain in performance I think the reduction of rotating mass by getting lighter wheels is the least costly overall for the amount of performance you acquire..... They are the least labor intensive, have no negative impact on other components and in fact lessen the load on drive train, suspension, steering and brake components... If you decide to sell your car, you can change back to stock wheels and sell your wheels right here on FitFreak or anywhere else online where there is a market for them.. Lighter wheels and tires are by far going to improve your performance more than anything else you can do a car with an engine as small as these cars come with and have no negative impact on resale value and you don't even have to get dirty to swap them out.
