1.61 60ft - Having trouble hooking

 

How is the idle with that combo. Is it smooth or does it sound like a harley. I dont plan on tracking my car or drag racing as a regular event but more as a very fast sleeper (daily driver).

With the cam gears I am assuming you are going pretty agressive and it more than likely sounds like a old time V8 running straight pipes. Let me know.

Are their others on this thread with the same setup that can also comment?

I am getting close to my decision. I think the HKS is plenty agressive for me...its just deciding on 272/272 or a combo.

 

Hey Chris,

Here we go again.

If you can afford it, Go PiPeR =)

 

alright Quack. i know mate, but with some people you just have to keep telling them over and over again before stuff sinks in! LOL

Chris.

 

The idle is like stock with the AEM EMS. If you don't have the EMS then is lopes and yes, sounds like a Harley. It's bad ****!

 

Well I spoke with Buschur and they recommended the 264 intake 272 exh. They tried the other combo and were happiest with this setup from what I understand for a daily driver.Money is not an issue , I just dont want to buy something thats going to substantially change the feel of the cars stock form at idle. From what I am reading the pipers are a little more agressive.
Thanks for your input

 

here i go again.

Tampa Turbo. mate please just speak to Piper or Qantum Racing about these cams! trust me they are the best. they are more aggresive than HKS but thats what makes them a better cam!

thanks Chris.

 

ok, I'll check them out. Thanks

 

One question: Everyone keeps saying the 264 is great for low end power and the 272 and all the others are great for higher end power, well at what rpm does that switchover take place? 4k+? 5k+? 7k+? I don't expect my car to ever see 8k - 9k rpms so to have cams that the primary powergain is up there is pointless to me.

 

Its Guack not Quack and the name comes from a nick name my buddys gave me because I was born in Guatemala (and Im a huge fan of the Bond Lifestyle)

Back on Topic:

The pipers are more aggressive but are also less lopy due to the lower duration. Go to their website, its very informative. What cam setup is EVO 400 using?

 

First you have to determine what your goals are.
Are you looking for broad smooth power over a wide RPM range or are you looking for super peaky power across a very narrow RPM band?
Will your EVO spend all or most of it's time on th street, the track, the dragstip? Can you live with a mildly lumpy idle or a very lumpy idle with stalling?
Cams can be designed for very different engine characteristics which suit individual driving styles.

Also, comparing duration and lift between companies can be misleading depending on how each company takes their measurements. Brand X's 270deg. of duration and 11.0mm of lift can be significantly different from Brand Y's 270deg and 11.0mm of lift. Duration at what height and lift at what rocker arm ratio is necessary to perform an apples to apples comparison. Also, don't forget the all important ramp angle designs which are often overlooked.

Then lastly, you should entrust a good tuner to tune your motor with those particular cams installed. Not just Wide Open Throttle in one (3rd) gear. The cams affect your 4G63 from idle (850RPM in no gear) all the way to 7600RPM in 5th gear and everything in between. A good tuner should provide a proper tune across the whole load and RPM range for their particular cams.

 

im soooooooo sorry about that mate. it was a typo, honnest!

i think EVO 400 is running Piper Rally cams, although he may have gone for the slightly mad race cams. LOL. you can still be seeing very nice figures (thats across the board not just peaks) from the piper ultimate road cams as this is what pipers demo car was running (400lbs ft and 400 bhp from 1.6bar).

alternatvely you could go for some mad solid lifter race cams like what moses is putting in his motor. 12.5 mm lift anyone?

thanks Chris. (and soory agian Guack)

 

No problem bro, I get the Quack thing alot and am kinda used to it. 12.5mm lift is INsAnE. Definatly not needed for my daily driver. Once I can afford it Ill go for the rally cams. Maybe even that stroker kit AMS has for under $2000. The real problem with going this route is that if I get a stroker and piper rally cams then I might as well get a turbo and a porting job done. Its an endless upgrade path. I think I'll play the lottery this week, maybe it will be me.

 

LOL. i know what you mean mate, i keep hoping my numbers will come up but they never seem to. i recon you will have a problem running the stock turbo on a 2.3 and rally cams. it will spool nice and quick, but you will be running out of steam by about 5k. it will be like driving a diesal. LOL. turbo would have to be a def and you may as well get the gead done to. then there's the inlet manifold and the........doh!!!!

chris.

 

Sorry i am kind of unfamiliar with cams, But what combo of cams will give you the most power over the entire rpm band. Or does the car need to be tuned for the cams to give even power throughout the rpm band? And also what cam setup would be best for daily driver use? (considering you want close to stock idle)
