HMT:DIY free horsepower
 

Just like the title says. I know everyone has their own little ghetto ways of making their cars run a bit better. So post em up. Like disconnecting the throttle body heater or shimming the hood to get added ventalation, or even some racing trick like brake boosting. Lets all share in the ghetto free HP wealth. O0

Re: HMT:DIY free horsepower
 

I took out just about all the coolant lines to the intake manifold and picked up a few ponies when i was n/a. I used to take off my power steering belt when i was at the track to pick up 2 tenths, and i ditched my a/c. Taking 50lbs off the front end of the car was noticeable for me

Re: HMT:DIY free horsepower
 

took out all my AC ----, front and rear bumper supports and fiberglass fenders and front/rear bumper.

Re: HMT:DIY free horsepower
 

i keep my weight down so i can go faster and don't let anyone else ride w/ me.

Re: HMT:DIY free horsepower
 

Colder thermostat, removed rear seats, removed carpets.

Re: HMT:DIY free horsepower
 

i made my own CAI out of my stock ait box. kinda hard to explain, but bacially, i made a tube that goes from under the air box down into the fender well. it worked, and i noticed a difference. and i kept a filter.

Re: HMT:DIY free horsepower
 

no bumper support ,a/c ,ps ,cruse controll put a manual rack in , wiper motor (rainx the window) sound matting under the carpet , thats aboutit and also turned the boost up

Re: HMT:DIY free horsepower
 

the altimate free HP is to CRANK UP THEB BOOST >:D

Re: HMT:DIY free horsepower
 

Air chissle out all the sound deadening material and theres more matting behind the dash. Not exaclty HP but it helps.

Remove the slack from your throttle cable. You wouldn't believe how many cars I see that have tons of slack and when I point it out people just shrug their shoulders and go " uh huh..."

And the most obvious, A TUNE UP! ::) not just plugs and bling bling plug wires, but fuel filter, carbon cleaner, eveything.

Re: HMT:DIY free horsepower
 

I just blocked off EGR and bypassed IACV and TB coolant lines..

disable IM butterfly valves by disconnecting the solenoid from the vacuum source....

Re: HMT:DIY free horsepower
 

can you explan how you would pic up some hp from taking the coolant lines off the t/b ?

and why would you want to take 50lbs of the front of your car

if you could answer any of them that would help me out alot in thinking about how insaine your reply was thanks

Re: HMT:DIY free horsepower
 

coolant lines on the intake manifold heat up the incoming air, the colder the air, the more dense the air is, hence, you can make more power.

and removing weight beheit above the driving wheels or not would lighten the car (its easier to push around a light car then aheavy one) although traction might be decreased.

please show me proven proff that the coolint lines to the intake manifold show any less heat going to it that is the most stupidest thing i hurd the only thing it does is stop it from worming up faster on cold days

and removing weight from your front will give you more wheel hope and more traction probs so how is that making you go faster by spending more time sitting there spinin your tires

Re: HMT:DIY free horsepower
 

listen little fucknut
Nobody said these mods give you 60 whp. ::)
and btw a car with the right suspension mods doesnt hop even if u remove 200 lbs

and for fucks sake learn how to quote

Re: HMT:DIY free horsepower
 

try bypassing your im coolant lines and touch the intake mani after some time..i bet it's much cooler...maybe that is why people who make custom sheet metal intakes don't use the lines?? it might be .55 hp...but we're just looking for little stupid tricks here

Re: HMT:DIY free horsepower
 

Look, I'm not trying to pick a fight but I have tested this coolint ( mod) and got completely different results. Unfortunately I didn't do the super accurate "hand temperature" test.

I took my car for a 10 minute drive and came back to my house and let the car idle until the rad fan came on (which is when the coolant is the hottest it will be) and took a reading on my manifold with the coolint lines hooked up using an infrared temperature sensor. I conducted the same test the following day with them unhooked and the surface temperature was exactly the same. I do not remember the actual temperature (mid 200's) but it was pretty well the same. I believe it was hotter with it unhooked actually, but that could just be a variation in the outside temperature as well or something like that. Regardless it was within 1-2 deg so it was the same for all intensive purposes.

While I appreciate that you may have found that it was cooler I did a test with an accurate instrument and there was no difference.

Re: HMT:DIY free horsepower
 

DIY MBC,AND ELECTRIC FAN CONVERSION O0, if oyu dont want to make a MBC Shim the waste gate and up the boost that way

Re: HMT:DIY free horsepower
 

Please give me proven proof what reality is? could you please?

how would removing the lines make the intake manifold warmer, I call BS on anything you say, moron.

Re: HMT:DIY free horsepower
 

^^ yup, HMT boost controler is probably the most bang for the buck on my build.

Re: HMT:DIY free horsepower
 

Wow if your mechanical skills are anything like your english you must be totally correct. I noticed your last post has a lot of big words in it and was edited, did you spell check it???

Re: HMT:DIY free horsepower
 

ok it works i bet it adds a good 10hp go for it im going out to my car to do it now

Re: HMT:DIY free horsepower
 

file down the trailing edge of the butterfly in your throttle body, and polish it.

Re: HMT:DIY free horsepower
 

i've had some friends using thorottle body spacers that are spiralled..(homemade ones of course) just like on carbed cars.. and they claim they work decently..this would be on an NA of course

Re: HMT:DIY free horsepower
 

Speaking of removing the power steering belt, could you not rig up an electric power steering unit? it does not take much effort to turn the power steering pump, i'm sure a small 12V electric motor with a switch would work great.

Re: HMT:DIY free horsepower
 

whoops i messed up guys... you need to cool your intake manifold with 200 degree water because without them it heats up too hot and will melt down... just like a nuclear reactor yO...

LMAO, aluminum conducts heat very well... so removing unneeded coolant lines to the intake manifold will make it run much cooler, and should give a power gain (small but it might be noticeable) the reason they are there is for emissions purposes to heat up the incoming air fuel charge and to prevent icing at the TB etc... (ie... nothing we care about).

Im really not sure if you could run the power steering off of a small motor... In my own testing running with the ps belt off (ps only) resulted in a 2 tenth improvement quite consistently, but can make you torque steer worse depending on how bad your traction issues already are...

Re: HMT:DIY free horsepower
 

he is talking about the weight of the PS and AC equipment. That includes all the lines, belts, compresor, pump, condensor, and some other parts. Not sure how many pounds it is, but the drag and weight reduction can't hurt ya.

Re: HMT:DIY free horsepower
 

ok so i've heard about the coolant line thing many times, but in the guide, the guy says you MAY need to block off your idle air control valve if you experience erratic idling. why is this? i want to do the free mod as i'm a cheapskate.... but i'm not touching my IAC valve.



O0 does anyone like guy sebastian?

Re: HMT:DIY free horsepower
 

Some cars have a Fast Idle Thermostat Valve in the TB. It's a valve that lets in a little more air when the TB is cold to help the car warm up quicker. The rinky dink little washer inside can wear out and make the idle fluctuate. IIRC only OBD I Hondas have the separate FITV. OBD II cars let the ECU adjust the idle form the coolant temp sensor. Read your helms though; I may have it backwards.

The reason you dont see a big gain from just unhooking your coolant lines from the TB and IM is because of heatsoak from radiated heat in the engine bay and heat conducted to the IM from the cylinder head. Try wrapping the IM with heat reflective aluminum tape and installing a hondata im gasket. You can also make your own if you can find some high temp phenolic.

Wrap fuel lines in the engine bay with thermal wrap.

You can also cut away a lot of the trunklid and hood stiffeners. It's not a ton of weight but every little bit helps.

On an NA car use a new O2 sensor. I've noticed again in throttle response after replacing my 30,000 mile dirty one with a new Bosch one. I've heard the the Bosch ones are calibrated a little leaner. Thats why I say NA.

BTW, the new EP3 Civics use an electric power steering pump.

To anyone who thinks pumping 190-200 degree coolant through the TB makes your car faster, I've got an electric supercharger to sell you.

Re: HMT:DIY free horsepower
 

so I can convert to electronic power steering? I am wondering what type of belt I would use, THe motor would be a 1/4 horsepower 12V about the size of a wiper motor, I can make the bracket as well to link the 2 and I can make a pulley, but I was wondering if there is a small enough belt for my application.

Re: HMT:DIY free horsepower
 

Weight reduction and learn how to drive aggresssive(wot shift).I recently drove a stock srt-4 v.s a stage one and won due to aggressive driving. :P

Re: HMT:DIY free horsepower
 

Filling up the motormounts helps cut down vehicle reaction time,and there's less stress on the manifold.
Cutting the exhaustpipe off after the bend by the gastank,add a piece of pipe on there and have a sidepipe..you loose the weight of bunch of bends and a muffler and flow is better.


good topic this here...except for the idiot saying coolant lines on the TB are better

Re: HMT:DIY free horsepower
 

So Just by slipping the PS belt off It gains about .2 tenths. That doesn't do any harm to the pump? and I can just slip the belt right back on and it's good as new right?

Re: HMT:DIY free horsepower
 

if there's nothing else being driven by that belt..you can just take it off..it won't hurt it

Re: HMT:DIY free horsepower
 

I just took mine off today to see if I feel anything other a hard to turn steering wheel, lol, I plan to convert to electric power steering soon enough.

Re: HMT:DIY free horsepower
 

Don't forget this little gem..

It's intents and purposes as in, intentions.. get it? Now that you know, please use it correctly ;)

Grammar NAZI out

Re: HMT:DIY free horsepower
 

I have heard many times about blocking off the mani coolant lines and know that it does make some difference, the same way as i am looking for some kind of material to use to make a HM intake manifold gasket that will not let the head's heat soke through as fast. I looked into the hondata IM gasket they make for that purpose for $60 and they said that at sitting idle when you take off at WOT it take's exactly 14-17 sec for your intake mani to cool down the soked heat from the head whichis cooled by the fresh air coming through the TB. Out of curioustity though what exactly do ya do to bypass the IACV I have heard if you either dosconnect it or bypass it it will help bad bouncingidle's which is a big prob of mine, but what exactly do ya do? I heard something about cutting a coke can and placing a sheet of the tin can inbetween the mani and IACV?

Re: HMT:DIY free horsepower
 

i took a dump on my hood.

Re: HMT:DIY free horsepower
 

What motor were you planning on using to drive the pump, anyway?

Re: HMT:DIY free horsepower
 

power steering is for pussies, remove it, or run with it, oooo 2 tenths, big ------- deal jerk off. don't waste your time with a gay ass electric motor, think about it, that motor has to be spinning all the time, you really think your alternator can charge your battery, power your stereo, your lights, AND turn this pump at about 2000rpm? i don't think so.
