View Full Version : Cut engine cover

12-03-2009, 12:43 PM
The first mod I did to my car was removing the engine cover. Someone once posted a 2hp gain with cover removed so I thought why not, But it looked ugly so I got the jigsaw out and started cutting. From what I heard the cover made the intake very warm resulting in all our cold air turning hot at the last hurdle. Just thought I would share a pic after seeing so many engine covers missing from engines. PIC WONT LOAD WILL TRY LATER:nuts: Maybe IM wasting my time doing this but it was free and logic behind the theory seems reasonable

I removed the bonnet off my car one day and got an extra 3.7hp, although i left the engine cover on so maybe i could of made more from what you are saying! :D

I heard that claim too. I heard it is 1kW with that cover off, and 1kW with the front rubber strip removed (or cut just before the snorkel). I did both and run with it for a few months - to allow the computer to adjust, etc - but I couldn't feel any difference (not that you would feel 2kW anyway); I ended up putting the cover back on, but the rubber strip is still cut.

Yeah, I removed the engine the other day and now can hardly keep traction to the rear wheels

Seriuosly, this will make SFA difference as the air travels so fast through the manifold it hardly has a chance to touch the sides.

Also the heat within the engine bay will warm up the manifold and will provide no cooling at all

All you have been able to acheive is wrecking a nice looking engine cover.

For all those smartasses and naysayers - this was a demonstrable gain that was repeatable (the cover was removed and and then remounted).

It was a small gain but who cares?

Oh get real, its a freeken piece of rubber "dyno backed" my ass, you do 2 dyno readings side by side guarantee you there will be a slight variance of possibly 2hp.
but hey if you think that removing whatever it is your removing will give you 2hp and if it'll make you sleep at night, sure, it will.

while your at it, ditch the whole exhaust system, and headers, dont need them, just a restriction, motto with engines is, get the air/fuel in and out as quick as possible.
mightaswell get rid of your power steering and air con aswell, engines turning less - more free power.

Shame I dont own a 380?

Shame I dont ruin a *********** $25,000 car by HACKING into the engine cover with a JIGSAW....:nuts:

and can someone tell me how removing the engine COVER will increase HP? air enters through the air intake not the engine cover.

tuff i think he was saying that it helps keep the intake cooler. But seriously, you wont notice i thing regardless. Might as well say that you should only drive when its cold outside, otherwise if its too hot you might lose power lol

Sorry if we intrude in this exclusive 380 section but last time I looked it was a club and everyone has the right to comment. If you want you r exclusive place, bugger off and form your own 380 club.

It may look better cutting it, I do nto really know. Dont really care but power gain out of cutting a bit of plastic yeah what ever. The air passes through so fast as I stated will make stuff all difference. Chuck your car on a dyno and do a few runs, you will get a difference even if you do nothing.

Just because someone does not choose to own a 380 does not exclude them from posting here. If that was the case you would have no right to post anywhere else in the club which is NOT the case.

Oh and some of us have either owned or had 380's long enough to get an opinion on the car although if you look at the topic, this does not really refer to a 380 as a car but to a claim of removing a bit of plastic that does not alter or assist airflow or anything else for that matter aside from looks.

If you truely believe that the engine bay heat will cool the manifold then more fool you. If you do this because you think it looks better than good on you as this would be the only reason to make a mod like this and yes, I also think it looks ok for the record.

Now excuse me while I go let the air out of my spare tyre to lighten up the car and get an extra 5kw from that as well (will plumb the valve into the TB so dont worry, will be just like forced induction)

I think the point here is zero cost mod weather it be cut the engine cover or no engine cover like me. It may produce 2HP maybe only 1HP but if you think all little bits aren't worth bothering about you might miss out on a lot more ...... 3HP for a K&N panel filter ..... nah not worth it ...... 5HP for a plastic snorkel ..... nah not worth it ..... hmmmm hang on all these useless mods add up to 10HP ...... hey thats worth it!

If Specialk chooses to cut a bit of plastic under the bonnet who cares, its his car no one elses. He probably now wishes he didn't share it with the club I'd say :redface:

mozzaldinho
13-03-2009, 07:01 AM
Wow, all of your are so uptight.

Who cares if he makes this apparent 2HP or not, it was his choice and is acting on what someone told him. I personally think it looks better too that a std engine cover.

You don't see us continually bagging Paul about his rice machine ( a v.fast one)....hmm wait bad example.


Im just saying that everything you do is personal, its up to you, im sure he really doesn't care if he gets the HP or not, its just that if it is true, every little bit counts. But as some say, if only it was that either.

Prove him wrong with some facts but don't bag him.

Agree with you there Frooz. It is becoming more evident that people are only concerned about what they beleive in and if someone offfers a differant view then they are hunted up. The mods on the Magna's have been around for a long time but the owners of the 380 are being bagged because thy are comming up with basic cheap mods that are showing small but increasing power changes. Not everyone has the funds to spend thousands on their cars.
I have used a number of these mods and am please with the slight changes in the 380.

And for an Administrator to view those sorts of comments shows the direction this forum is going.
Well i guess i will be banned or suspended for a while for having a bad comment for an administrator.

grow up guys we are all here to exchange our knowedge we have for our cars not run people down because they may have found something useful for themselves

What is wrong with you guys

Just because I am an admin does not exclude me from having a right to state either fact or opinion.

If you bothered to read my post and others before it, I was simply responing to a comment stating that members who do not own 380's have no right to be in this section!!!!!!

As for being here to share knowledge, when someone posts up a mod that is supposed to do this or that and you guys disagree, you jump on them!!! What gets to me is the amount of false information on these forums of late and all of these wives takes going around, some of which have been plain dangerous and have potential to harm a driver or innocent person. (not referring to this of course).

Show some true CONSISTANT basis for this mod improving HP and then fair enough but good luck in finding 2hp.

Further, there is absoluteley nothing wrong with questioning the claim of 2hp for this so called mod. If you look at the logic of it, which I have also put forward there is an arguement against the claim however I have also stated that if this is also for looks then go for it???

In so far as being banned, get over it guys, you will not be banned for expressing an opinion in the way you have, it opens up healthy discussion.

As for the OP I still stand by the idea that there would be no difference in power especially under speed. AGAIN I say however that if this in the owners opinion improves looks, then awsome way to make something look better for free.

Fair enough Mal, but you don't need to say things like that. (above)

Hey i don't think there will be any power made, but i'm on not gonna carry on like TUFFTR and say he has wrecked a whole car by cutting the engine cover, or you and say what you said above.

Holy ****,

I spent money to prove some gains with some small mods and those mods were tested over 15 runs on the dyno !!!

What's more - I didn't suggest to the mechanic to remove the cover; he came up with that himself because it had been PROVEN TO WORK on other non Mitsu models, by lowering the fuel feed and fuel rail temperature. It happens to work for the 380, maybe not Magnas or other models.

If you think it is BS you should have said so back then when I posted up that info! Some of the detractors here have posted in that thread.

I've had more dyno runs than any other 380 here and it's no accident that the car is putting out what it does.

Folks its just an engine cover. Its his car if he wants to mod it chop it its his car.
2hp yeah i get that every morning when i leave for work and loose 2hp on the way home from the mild humid weather we are having.
Cant believe people are getting emotional over this.
Probably get another 2hp by pumping up my tyres a little more...

Good on you guys i say for trying all differnt types of small mods!

I wasnt going to mention anything about the behaviour in this thread, but after reading 4 pages, 3 of which contained nothing constructive, i have to have my bit and say - When is this forum going to change?

Healthy discussion is fine, and yes, may become quite heated - which is when mods & admin step in - but when admin's engage in smart **** comments - how can ordinary members be expected to behave?

Anyway, back to the topic, personally, its not something i'd do to my car - it cost too much money, (the car that is), but i appreciate the lengths some will go to for an improvment to thier car

They are still members off this forum and can still be a smartass like us all, then when they go all straight and nazi like people complain that they aren't interacting on our level:nuts:

What do you want in a forum? want us to all turn to pansy's and just congratulate and never question someone when they cut off a bit of plastic that apparently gains a DYNO PROVEN POWER INCREASE.

I think, if you wanna mod your car, do real modifications to it, exhaust, intake, blaa blaa etc etc

What madmagna say's is correct, he's been in the trade for 20+ years and if he wants to be a smartass (to a degreee) he can, he's only human, post a stupid thread, get a stupid answer.

I find it funny how everyone ALWAYS says just HOW MUCH R&D mitsubishi put into there air intake systems and how much better they are then CAI's or all this boloni, but hey remove some plastic from the intake, 2HP+ THAT MITSUBISHI OVERLOOKED WHEN DESIGNING IT!

You wanna mod your car and say yeah it's dyno proven and to half the AMC community be a laughing stock, well, welcome to the WWW, you dont like it, grow some nuts, or dont post your mod's on here...

Now maybe cutting the engine cover will not release that mighty 2hp that full removal of the engine leeching plastic
fantastic suckerfish will do, but anyone has the right to cut plastic anywhere, way they choose....and post it right here, right now! In fact, I want to see the bit that he cut off!

Chev powered commodores do this all the time. Removing it assists by not being a heat "trap" or acting as an insulator, aiding heatsoak into intake manifold and everything else bolted to the top. It may only help by a few degrees, but so what if it works, do it. If you want to cut it or remove the whole thing, thats up to you.

I wouldnt have thought a $15 piece of plastic would have done what it did either (the US snorkel)
