Cams.!

[Gst to the max]

Hey everyone what's up, I wasn't sure where exactly to post this, I searched the forum and didn't see my question. So here it is, I want a nasty Loap out of my 4g63 I've listened to some kellford 272's and I like them
But there still alittle fast for me. So question is what cams should I get to make my car loap like I want?

unless your car is ready for a large cam the lopeyness you want will actually make the car worse to drive.

kelfor280 or 288 are some of the biggest cams but make sure your ready for the step up before you do it.

If you plan on running the 16g for a while id run some bc 272's, hks 272's, fp2's, gsc s1's. Something along those lines.

They had great results from the bc272's in the cam test thread.

Personally i wouldn't run anything even close to the size of the k272's, unless it was a drag car.

 

[boost97gst]

Crower 272s will give you a lope. Not like a 280-type lope, but def sounds mean. Ill try and post up a vid of my idle.

 

[Nicklepage1010]

You want to spend money on cams to make your car SOUND cooler?

Put on your flame suit.

PS: Kelford 288/280s are pretty much as "Lopey" as a DSM can get. If you want a car that sounds like its going to stop running, buy a v8.

Thanks to everyone that gave my advice on which cams, to the rude person below everyone that was uncalled for, I like the sound of a lope yes v8's are over rated. Anyway what all is needed to run a 272 and still be in the easy driving area. My profile is alittle not up to date but I'm installing a walbro 255 prob today and 650 injectors if that helps any?

 

[3kgt2nv]

272 are almost drop in. they should be degreed for best performance but alot of people dont. as long as your not trying to rev to like 8500-9000 rpm they will be good and give some decent power.

 

[Gst to the max]

8500-9000 that's crazy unless you like the Magnus car that pushes 11,000 but alright thanks I think I'll put some kellford 272's in it and post a video when finished. Thanks everyone!

I don't think kelford 272 cams are what you really want, they are usually recommended to use upgraded springs with them. I would suggest hks or delta h272 cams as they are not as aggressive. Also, I would be weary of installing those injectors and fuel pump without at least a wideband and tuning device (link/afc/eprom chip, ect) and you may even need an adjustable fuel pressure regulator.

 

[Gst to the max]

I have a aem wide band, and the reason for install that pump and injectors is my car is running a lil on the lean side. Like idle is 13.1 I talked to the guys at dsm grave yard, they said to install the injectors if they run rich just swap them back out.

 

[91stocker]

Yea kelford 272's are bigger then most peoples 288's. They purposely mislabeled their cams so they would make more power then other 272's. Kind of a marketing gimmick really.

They wont start making power until 2000 rpms after the 16g has peaked. The larger cams will also cause slower spool and make the 16g fall off harder then it already does near redline.

You will loose a lot of low end and streetability.

There was a thread on this just a couple days ago.

Edit: o and you have no tuner, jeez. /facepalm

 

[honda_burner]

Shouldn't be trying to fix a problem by throwing more aftermarket parts at it.

Then what would everyone els like me
To do about my car running lean cause I would love
To know. I don't have a single boost leak my feul
System is free flowing I just changed the filter yesterday. I have a larger turbo than stock so bigger injectors make sence to me.

 

[91stocker]

You cant modify the fuel system with out a tuner, like link or etc. The maf can compensate for small changes, like upping the boost from stock 12ish to 14-15ish. On the stock turbo that is.

As far as running lean, just turn the boost back down until your not running lean anymore. Whatever that ends up being is the max you can run on your set up with no tune.

I have a aem wide band, and the reason for install that pump and injectors is my car is running a lil on the lean side. Like idle is 13.1 I talked to the guys at dsm grave yard, they said to install the injectors if they run rich just swap them back out.

That is actually rich for idle. I'm not sure what the stock target afr for idle is, but i run my idle between 14.7 - 15.3. No boost, no load, don't waste the gas.

 

[Gst to the max]

13.1 is rich? I've always heard 14.1 is a good afr and anything over 15 there's a problem and the only reason I don't have a tune is because of family issues and money is foucosed on more important things at the moment.

I'm having a hard timing even believing that the graveyard told you to just blindly start swapping injectors. I'm also assuming you told them about your 13.1 AFR and they still suggested this? Eug.

I'm betting you're not lean at all. Get a logger, make a log and find out.

 

[Gst to the max]

Would you like me to screen shot the messages from dsm grave yard I'd be glad to?

Let me understand you correctly you want a nasty lope and that's it? What about performance? You can get as nasty of a lope you want out of stock cams just by increasing the lope separation angle. Just trying to understand what you want to do before I suggest a cam.

From what I have heard about them nothing really suprises me

A bigger turbo doesn't do anything for your fuel trims at idle.

 

[BLOHS7844]

the lower the afr number, the richer it is. 14.7 is perfect for idle. Any lower and your too rich. Don't just start throwing parts in your car without knowing how a car works. And a tuner isn't optional with bigger injectors.

 

[delta448]

I talked to the guys at dsm grave yard, they said to install the injectors if they run rich just swap them back out.

How are these people still in business?

650's are about one and a third times the flow of the stockers. I'll be very surprised if you can even start the engine without any injector compensation or fuel pressure adjustment. At least install an SAFC before you try to drown your bottom end in fuel and completely wash out your rings.

And people wonder why DSMs aren't reliable...

-Also, fix your exhaust leaks and your WB will stop telling you you're lean.

You can get as nasty of a lope you want out of stock cams just by decreasing the lobe separation angle.

This is perfect if all you want is...

a nasty Loap

...and don't really care much about actual performance. A set of adjustable cam sprockets should be waay cheaper than a set of cams anyways, right?

 

[Gst to the max]

Well how do you adjust that? Cause I would love to have a nice lope out of my car. I don't have the money for cams right now. If I can get a nasty lope out of it by adjusting something please let me know.

So I guess they have made me look like a idiot, that's wonderful I was just going off what they told me.

 

[delta448]

If you retard the exhaust cam and advance the intake cam, you'll decrease the LSA and add overlap. That will turn your idle to shit just as effectively as big cams.

 

[Gst to the max]

I'm new to most of this but am knowable of most of it. But how do you slow down the exhaust cam? And will that effect throttle response?
