Thanks Chet!

Yup. There is more, I just cant remember it all right now, lol

 

[chetrickerman]

Simply amazing... I wonder what the weight difference on itself does for the handling/performance of the car

Has to be an interesting ride!

Congrats!!!

They say that the Evo 8 & 9 drive like a go cart compared to the 10. Well its like a go cart, but better, lol

 

[chetrickerman]

You got the rear seats in there right, but just removed the assembly behind them? Oh and what exhaust?

Yes. Ams DP, UR TP, AMS CBE

Have you seen the Kronospark batteries? They have some ultralight batteries (1.3 and 2.7lbs.)
They will soon have a Lithium battery...here are the specs

• Weight: 1.26 lbs/.57 kg
• Pulse Cranking Amps: 228 PCA
• Amp hours: 3.8 Ah
• Size: 5.5" x 1.9" x 2.5"
• Nominal Voltage: 12.8V

Not really worth it to spend any more on another battery unless they arent hugely expensive

 

[chetrickerman]

So you could save another 10 some day if you get a Ti exhaust. You're not far from the 2900's!

I have heard the front / rear crash beams do not exist on the Euro or JP cars, do you have any links to proof of this?

Yea, once I do those things on the to do list I should be in the 2900's

I already started on the HVAC

The 1.8lb is $225

Maybe one day, lol

What intercooler are you using?

Perrin

What wing is that Chet?

APR GTC-300

 

[chetrickerman]

Makes me want to go full race car build. lol

Although, everything you've done to the X you can do to an 8/9. Imagine an evo in the 2600lbs range.

Correct, but our chassis, awd system, and engine are better

 

[chetrickerman]

I agree, my buddies and good friends I race with all drive IX's and keep egging me to get one. my goal is to beat them in the X, no way am I swapping cars, I love the X. But, I just am short like 10 years of racing time and so need experience to catch up lol.

But doesn't help one guy just raised 30K to dump into a full SM modded IX on 315s with a custom widebody and fp red running 116octane race gas. Probably will never beat that car lol.

But thanks for the info man. I want to shed some weight so that's the real reason I replied, so I'd be subscribed to the awesomeness.

Awesome! Thanks for posting it up!

I appreciate the kind words

I always remember one thing, there is always someone faster out there

 

[chetrickerman]

If you do, I'll take your AMS catback immediately

Also, cool thread

Hmmmm, interesting

Crazy man! That must be one loud ride

Its not really loud. But I do like my cars loud, lol

This thread is an inspiration to me.... I have been wanting to this to my car ever since I bought it and took the first corner. However my girlfriend would hate it if I did this.

Do you know how much you really saved removing the A/C components? My car is still my daily so I guess I could do everything you did, minus the A/C.

Thanks!

Well the A/C compressor is heavy as hell. The condenser, lines, and core are probably only 10 pounds total. But its nice because you get rid of the parasitic loss of the A/C as well as the weight.

My wife hated the fact that I got rid of my A/C, but she got over it, lol.

Also, since you live in Chicago, you could get away with no A/C. If you were some place like Texas, then probably not. I grew up without A/C, so Im used to it

 

[chetrickerman]

Thank you sir!

I did have a quick question - did I miss a brake upgrade (two-piece rotors or big brake kit)?

I have the 1pc girodisc slotted rotors right now, 2pc's are on the to do list

if you going to a full racing build later , here is some ideas


Stock heater vs my heater

Heavy balance weight on the drive shaft, makes no difference, its on or not, in my experience..

after you took out everything including sound deathening material etc. and when nothing left , then you have to start cutting the parts out, which was meant to be cut out and later lightening up the engine bay. ie removing ABS units etc. getting instead the pedal box set up etc.. But be careful with heat shields!!! keep most of them on it is important!
cutting parts out from the interior:

Part of the junk was took out

lightening the rear doors:

then the empty engine bay:

the finished light front / engine bay set up, At least part of it on the pictures, notice no ABS and other crap in there anymore

this for now
Nice thread though! I like!!!!

Awesome, simply awesome. I NEED more info on that heater, as long as it doesn't cost more than $400, lol

by removing the crash beams, does this significantly change the safety of the car if you ever get into a crash? can we also get a picture of what your interior looks like now(with seats and dash? Thanks!

The crash beams are only there for "parking lot crashes" (10 mph and under collisions)

Nice work chet! How much weight did you save from removing the sound deadening on the firewall? I hate how that crap looks.

BTW an AMS lightweight battery kit will support the SSS sound system.

Well the fabric insulation/sound deadening doesnt weight much. I just removed it so it cant catch on fire

The AMS battery is pretty kick ass. I have had less issues with it than the stock battery

I've seen and Evo 8 at like 2300 pounds. It was so light it was illegal to be used its auto x class, they had to ADD weight. Wish I could find that video, someone posted it here at one point. Keep in mind, it didn't have a cage, or any real safety equipment.

Yea, but that Evo is just nuts

chet how is your gas mileage since you removed all that weight? Did you notice a difference?

Well with the weight and the bigger turbo I can get a little over 30 mpg on the highway on pump gas. With E85 I can almost get 25 mpg highway

Interesting thread for ideas, I guess strip out as much as you can bear to live without. I was also sizing up the rear seat and will be removing the heavy metal bars if I can still allow the headrest inserts to work somehow.

Some of the heat shields can be safely replaced with a sheet of DEI heat reflective material but elmininating it completely can be risky. With the stock turbo setup and heat shields you may be ok, T3/T4 setups with tubular headers you will want to add heat shielding or replace the stock with better coverage shielding. Just having the turbo seperate from the exhaust manifold by 1mm can send enough hot exhaust flow onto the firewall to melt your $2000 main chasis wiring harness. It's what took us out of the 2012 One Lap even this year.

What events do you typically run this car in to bring about such weight reduction? Seems like you are in the 500+ lb reduction area already which saves you from having to make an extra ~50 horsepower along with less driveline and braking system stress. :shades:

If you take out that frame there is no way the headrests will be able to stay in. Take them out, who needs them?

Once I go T3 setup (most likely the AMS kit) I will install those heat shields

So far I just run track days for now. There isnt much for a time attack circuit out here, but I plan to change that

 

[chetrickerman]

Nice Chet!!! Shit must be wicked loud inside lolol

Thanks. Its not bad. I can still have a conversation on my phone while driving.

yea chet post some more pics if you have them...I'd like to see the trunk / rear seat area etc.

edit: also, what are everyone else's thoughts on that driveshaft balance weight?

Ok, I will get more pics.

The driveshaft weight is 100% pointless. Just like the weight below the intercooler

Well, if I keep my car I think I am going down this route

I won't make it quite as light as yours as you removed some stuff I would keep, but if I keep the car, I would hope for around 3200 lbs or so.

3200 shouldnt be to hard at all

Odd, I don't even know where the driveshaft balance weight would sit, I'll have to take a look.

chetrickerman: We visited the High Plains Raceway just east of Denver this year for the One Lap, seemed like a really fun course although I only had 5 laps on it as my co-driver ran the morning session. Not sure where you are in Colorado as the state is pretty big. :thumbup:

HPR is pretty nice, but I go to Pueblo Motorsports Park instead. Its cheaper, brand new pavement , and is only an hour away compared to HPR which is almost 3 hours away

 

[chetrickerman]

Impressive, I for sure thought you wouldn't be able to hear your self think let alone talk to some one on the phone.

Its not bad at all, but I have permanent hearing loss, lol

the X's sound deadening is absolutely pathetic throughout the car. makes me wonder why they even bothered honestly

but the amount of work to get some areas of it out....ugh....I dread the idea (partly on my laziness)

I really am jealous though. I think if/when I get aftermarket lighter seats, I'll go on a weight reduction spree too

Yup, it is pathetic. I didnt notice any difference in sound before and after I removed the sound deadening on the floor

 

[chetrickerman]

I opened this thread fully expecting to see Chet's body photoshots while he was flexing his muscles.

*leaves with a broken-heart*
:inout:

I thought I emailed those to you

 

[chetrickerman]

Chet,

What do you think the weight distribution is now? You think you got any improvements on it?

Regards,
SS

Well its hard to remove as much weight from the front as I did the rear, but I think I got it pretty close. No way to know for sure until I get front and rear weights

This is a great thread, I am looking forward to following some of these steps as the Evo becomes less of a daily (it's at 50% now) - Kudos to you.

Funny thing is that when I first bought the car I thought - Shit this Mofo is noisy inside - ten months forward and I can't tell the difference anymore.


Looking forward to some pictures of the interior.

Thank you sir!

More pics! Give me a bigger shot of the engine bay so I can see the chopped off brackets

Its hard to see the modified brackets/bolts

Probably already have this one, but I had to remove the rear drivers side tow hook to install my exhaust. That piece weighs a good amount, and is fairly simple to remove. And I've had the car towed a couple times since removal, so not necessary in any way.

Yes, both the tow hooks back there are gone.

Thanks for the Idea though :thumbup:

 

[chetrickerman]

Flex-a-lite-Mojave-Heater-Assembly

Wow, I fucking love you. That is exactly what I want.

Can you tell me how much it weighs?

I can never have enough of you :ghey:

true story

 

[chetrickerman]

If you get that heater make a how to!

Will do

Seriously dont know the weight. It was an item we didnt weighted. it was an obvious upgrade for lightening the car up. So i have no clue. And now it is deep inside the car.
Also creates a LOTS of room under the dash!!

Yea, I removed the stock HVAC unit and there is a ton of room under there now

 

[chetrickerman]

Chet do you have superlight wheels?

RPF1's, duhhh

 

[chetrickerman]

so... no?

Lol, I wouldnt consider Enkei RPF1's superlight

 

[chetrickerman]

lol, was just having some fun. You can't argue with the weight of the RPF1's, especially for the price.

I know. Nothing wrong with having fun.

Yea, its hard to beat RPF1's price/weight, but looks, Volks take that cake all day.

I will have a set of CE23N's one day. BEST looking wheels on the 10's EVAR!

 

[chetrickerman]

CE28N's? lol

lol, typo

 

[chetrickerman]

BTW, in case you do not know this, it is NOT illegal to remove the crash beams
