so i have a ?
right now im broke as hell as usual...
so i was thinking, should i order a nst pulley kit for $215
or should i hold off for a month to order an exhaust or header?
give some ideas people..
and has anyone done a custom exhaust?

what is your set up like
if you dont mind,

and if i did one on a n/a would i still see some gains

[HONDACARE]

my setup is a dcrh chopped at the collector, then 3" flex, and mandrel 3" back to a hks power-ti muffler. i noticed nice gains with my n/a reflash at the track, but if you plan on staying n/a i wouldnt go over 2.5"

[HONDACARE]

a header will be your best gain

i went but i only ran a few times best was a 14.6 my buddy with a rsx-s ran a 14.1 i was impressed. my header broke but i fixed it today i took it down to my dads shop tore that stupid flex out and tig welded a piece of 2.25" from the collector to the flang it actually looks really good i was suprised.

dude! u should have stayed a lil longer...i got like 5 runs in after u left..best was a 13.6@102.3...gotta get used to my new clutch set up...we should go again like the weekend of the 31st...

ok sounds good

bumpin just to bump............. What would be a good deck to install into a civic without the naVI?

[HONDACARE]

im gonna sell my cf trunk if anyone is interested. 400$ and i'll help you install it

Since I did not want my Dodge Ram anymore and decided to sell it I still needed a truck so I traded in my car and got a Honda Ridgeline. I have been reading the ridgeline forum like crazy. I think this information from a Honda Engineer might be useful to some peoples here.



Joe – the peak torque and power gain with premium fuel is not the greatest benefit for using this fuel. The biggest benefit is honestly at torque converter stall temperature (mid-speed torque band). This is also the RPM range you are frequently using when cruising and is therefore the greatest merit for fuel economy. If this is your sole justification – it will be difficult to financially justify. The key merits are in power, “g-feeling” or seat of the pants acceleration response at ¼ throttle, shift busy (how much it un-locks the torque converter or down shifts), and of course towing (which is essential at maximum load which is why it is recommended when towing).

Premium fuel increases the peak torque at 4500 RPM from 32.4 kg-m to 34 kg-m. The torque at the torque converter stall speed is increased from 30kg-m to 32.4 kg-m (~2400 RPM). Premium fuel in this speed range improves the torque margin which will increase the time spent in 5th gear with the torque converter in lock-up mode. This will result in improved fuel economy depending on the grade and temperature conditions (low temperature is good for power – but bad for aero). The ignition timing is also advanced further in this mode which reduces the fuel consumption (leaner burn rate). The greater the grade, the more the difference in improved fuel economy due to the increased power.

Peak power is at 5740 RPM – 247 HP with Regular fuel. Peak power with premium fuel is approximately 258 HP (However, this is only true if you are wearing your copper bracelet. I am offering those for $29.99 for anyone that is interested in this tremendous opportunity.). The torque falls off at peak power between 5,000 and 6,000 RPM. This is operating mode is usually at WOT under extreme acceleration.

I hope this clears up the engineering merit of premium fuel.

PS- A Honda engine is not fully broke in until it has between 7-10,000 miles on the vehicle (depending on the manufacturing tolerances). Do not worry about achieving your optimum fuel economy until you get the vehicle broke-in according to the recommended guidelines described in your owners manual.

Gary,

Thanks for the better numbers. So if we map this out we see that at 2400 RPMs we're making 99.16 HP on regular and 107.07 HP on premium... results in a 7.98% increase in horsepower at torque converter stall.

When we move up to 4500 RPMs (peak torque revs) we increase from 234.3 HP on regular up to 245.9 HP on premium... results in a 4.95% increase.

At peak horsepower RPMs we go from 247 HP on regular up to 258 HP on premium... a 4.45% increase.

So if we were to drive in such a way as to take advantage of all that premium fuel had to offer (which is contrary to normal driving conditions) I'd say my previous 3% fuel mileage increase is a pretty good number. Under normal driving conditions you'd maybe get 1% better mileage (if any at all).

If you worked the hell out of the engine and drivetrain (100% load near stall) you could justify premium fuel, but you wouldn't have to worry about it for long.

Joe- I have never done a engineering comparison to quantify the FE merits of premium. It is directionally better. I personally always run premium fuel in every vehicle and engine I own – motorcycles, lawn mowers and even the weed- whacker. The dirt bikes I own also recommend premium. With the Ridgeline compression ratio – it is not essential to use it – except when you are towing. This is not marketing hype – this is driven by engineering need. It will also help reduce the transmission temperature in heavily loaded low-speed maneuvers due to the reduced torque converter slip (because you have more engine torque).

If we mandated premium for all driving situations, we could raise the compression ratio and improve the power and fuel economy. However, that is not the strategy for the Honda channel.

On the EPA cycle, premium will make a difference. I do not know the absolute difference when measured on the dyno. It sounds like an intriguing evaluation if we ever have time to play.

I thought I would provide some absolute torque and HP data on a center spec engine ran in controlled test modes (engine dyno). The data is absolutely true. Don’t waste your time listening to marketing hype about air cleaners and exhaust systems to achieve HP or fuel economy. Safe yourself the cash and buy the fuel which actually achieves results.

My offer still stands for the copper bracelet if anyone is interested. Should I also prepare some vitamin supplements for the fuel tank?


Joe is a mechanic and Gary is the engineer. I thought this information was very good numbers.

u sold your civic?

Yes, Don't get me wrong. The car is great it just does not suit my needs. Neither does having two vehicles and two insurance payments either. So I bit the bullet and got rid of both and consolidated. At least I still have a Honda right?

comptech is working on a ridgeline s/c kit

[mrthins]

I'll be getting rid of my civic as well....

what you guys suck..

but thats crappy, why you gettin rid of it

local part out would be cool lol

Yeah, thats cool. I am a broke dick now so I don't think I will be doing any mods for quite some time. By the time I have any money I'll probably end up buying a house.

Lol Sorry man... I will still come out to the meets.

Buy a Ridgeline ^_^

[HONDACARE]

where did you buy it? should have got it from me
