Question about WHP on our car - Club4G Forum : Mitsubishi Eclipse 4G Forums - 2006-2012 Eclipse Authority

jhun35 · January 3rd, 2012, 05:19 PM

What is the average percentage lost between our BHP and WHP on the GS? I know this varies of course but wondering what I'd be looking at stock and what to be able to expect with bolt on's. Thanks. (Oh and I did search and had a hard time finding anything on this, wording could had been wrong)

zumspeedsupra · January 3rd, 2012, 05:26 PM

What was it like 167ish to the crank they claim? Some member dyno'd stock and it was 135ish to the wheels. Full bolt on's I was 154whp and with a tune I was 179whp. IDK what i am currently. I'm running darksides tune and I'll have to hit a dyno when spring rolls around.

So looks like we are roughly a 20% loss at stock. This of course would vary with the lighter pulley, lighter wheels etc. Kinda wanting an Idea what bolt on's would get me with a good tune. I'm looking RRE Headers for sure to be probably my second upgrade. Haven't decided on my CAI (which will be my first) or the exhaust that I want.

FeaRlezZ · January 3rd, 2012, 05:33 PM

bolt on + tune will net u anywhere in the 170's for hp and tq depending mainly on how well the tune is

full bolt on u will lose power due to running insanely rich so stock will more likely be around 160whp. 135 is very low

Anyway to help correct this? So we can get the full potential out of the modifications ?

FeaRlezZ · January 3rd, 2012, 05:50 PM

^ only if u lean the car out a bit. just tossing on intake, headers, exhaust, tb on the car wont do much for u. yes it may look good and sound great but if u want the power u will need the FIC

zumspeedsupra · January 3rd, 2012, 05:53 PM

Fearless... it gave me 20hp with full bolt ons. It improves HP, the real power comes from the tune though. You lose ALOT of power from the crank to the wheels. I think it was pedro who dynod stock.

zumspeedsupra · January 3rd, 2012, 05:54 PM

I raced a member who was stock and I had full bolt ons. I beat him by 7 car lengths, same outcome every race too! So it does help!

zumspeedsupra · January 3rd, 2012, 05:55 PM

20-100mph pulls I believe it was

FeaRlezZ · January 3rd, 2012, 05:55 PM

lol mayb it was just my car

zumspeedsupra · January 3rd, 2012, 05:57 PM

Depends on the dyno as well, Corey who is from MA dynod stock and he was at 160 something to the wheels. Its amazing how you can get vastly different results from different dynos. But everyone knows crank HP is higher than WHP

zumspeedsupra · January 3rd, 2012, 05:58 PM

But your car probably runs better than mine Fear

FeaRlezZ · January 3rd, 2012, 06:03 PM

^ mayb if i was not about 4k miles overdue for a valve adjustment lol

forgive my ignorance but enlighten me on the FIC if you would. lolz

zumspeedsupra · January 3rd, 2012, 06:11 PM

Lol I'm getting close, I think I'm at 46K. Search bar my friend, AEM Fic

Gotcha, I'll look it up. The search bar seems to be either my best friend or my worst enemy. You never know what info is legit and what isn't.

im at 35k. it is actually recommended every 30k miles. due to all the pulls i have done i was in need even sooner

FeaRlezZ · January 3rd, 2012, 07:16 PM

although i did have the gt tb when i dyno'd stock so that was probably the killer

Does it hurt you more than it helps you?

Freeker · January 3rd, 2012, 07:48 PM

fwd 13-15% loss
rwd 18-20% loss
awd.... 20-25%

so how do rw/awd cars have the most power if they have the bigger loss?

mrgibs121 · January 4th, 2012, 08:51 AM

is valve adjustment outlined in the service manual?? mine needs to be done badddly (100k on the car never been done) also if i decide to have it done does anyone know what it costs?

mine is at 115,000 miles. Not sure if it has been done previously though.

FeaRlezZ · January 4th, 2012, 11:26 AM

valve adjustment is $300

it is not too dificult to do urself as long as u have the gap specs and a feeler gauge along with some basic tools.

I'll definitely look into this. I don't want to end up paying $300 for it. I have a few family friends who are mechanics and my dad use to be so I'm sure I can figure it out. Can I just google the specs?

pat_08GT_Spyder · January 4th, 2012, 12:49 PM

look up the Service Manual on tearstone.com, it's like the bible for the 4G DIY'er

This made my day haha. My eclipse didn't come with a service manual. Glad you pointed that out.

mwaterous · January 4th, 2012, 12:54 PM

I think there's a how-to on here for the adjustment, but for some reason the search function has disappeared.

your Eclipse didnt come with the OWNERS'S MANUAL, that shows you how to fasten your seat belt, turn on the wipers and open the trunk...

the SERVICE MANUAL shows you how to tear your car apart and supposingly put it back together to specs...

They just put real motors in cars that happen to be RWD, regardless of loss. a 600 hp monster will hook a lot better on RWD then FWD. plus, you can also run wider tires in the back without sacraficing any drive-ability

Hey now, I didn't ask how to do this? I acknowlegded I would look into it. People just gave info.

mwaterous · January 4th, 2012, 07:21 PM

I'm just busting on you man. It was my happy go lucky way of letting you know it was out there somewhere, but that I'm far too lazy to find the link for you... so I'll let you find it and if you post it back here I may even bookmark it... but then I'll probably still be too lazy to give it to anybody else in the future.

Haha I know, I'm just playing around too. I haven't tried searching for it yet. When at work I pretty much just hop on and off the forums when ever I have a chance. So I basically check what people have posted, reply, and start working again haha.

Xero · January 5th, 2012, 07:51 AM

You also see larger losses through an auto transmission than a manual.

jhun35 · January 5th, 2012, 08:29 AM

I wish the GS I have right now was manual. In WV, it's almost impossible to find a manual Eclipse or Lancer. No one wants manuals because of all the mountains.

NitroGlisson · January 5th, 2012, 02:54 PM

[QUOTE=Daxenth;

so how do rw/awd cars have the most power if they have the bigger loss?[/QUOTE]

It is not that they have more power it is that they can apply more to the ground. In the case or RWD the natural motion of a accelerating car is to rock backwards and weight coming off the front and going to right where you need it where the traction is occurring. So a less powered RWD car even with the extra power loss of being RWD will beat a higher powered FWD car most of the time...therefore the need to challenge them from a roll

fwd cars have less things to rotate
rwd cars have more things that rotate
awd cars have the most that rotates

fwd car: engine>tranny>axles>go
rwd car: engine>tranny>drive shaft>rearaxle>go
awd car: all of the above

it's all about rotational mass... less mass the easier it is to turn it

it's more in-depth than that but that is the basic idea

as stated above rear wheel drive cars hook better allowing more power to be put to the ground
