Integrated Engineering Race Cams 119.2hp GAIN!!!!!!

[derekb727]

HOLY CRAP!

Anyways, we DO have some cams coming out. I’ve been testing them the last week or so, dunno if you had seen the thing on our facebook page or not. Basically, I’ve worked out 3 grinds, a drop in intake, a medium full set, and a very big full set. We have been testing them on a 2L 20v, AEB head, RMR intake, a rams horn exhaust with a 5857 billet dbb. Ignition timing was left the same on all runs, a/f’s were 11.50ish on all runs, and we start at the same oil / air / water temps on each run.


The big set is more race oriented. It has a lumpy idle, even at 1000 rpms. It only draws 4-5 inches of vacuum- the brakes work fine, as long as you don’t coast in neutral. Been driving a set in my own car… Power gains on these are NASTY, I’m not done testing them yet, but we are looking about 95 bhp over stock. The 5857 .63 a/r is choking it up top a bit, but I know from running them on my own car with a big t4 turbo- they will make power way out there (9k-9200). With the little 5857, peak power is at about 8400. We really did these with the drag race / road race guys in mind. They could be street driven, but I definitely wouldn’t do it in a daily driver.

PTE 5857, 22psi, Q-16, 2.0L, AEB, 14 degrees

very impressive stuff

Holy f*u*c*k

Will there be any middle of the road cams for a daily/road race car?

[derekb727]

please can someone explain how they get these huge numbers? i dont think there is another set of cams on the market for any platform engine that yields a 26.4% hp increase?

[groggory]

please can someone explain how they get these huge numbers?

By making sub 5000 RPM suck they can make the top end very happy. And they're running a really big turbo on a larger displacement plus a larger intake manifold. Basically, all conditions are ripe to get as much gas burned as good as humanely possible.

say 7hp drop and 2tq drop, i doubt that will be noticeable even.

but that is still really impressive. no other motor 4g63, 4b11, ej25, b18, h22 etc. etc.have cams that yield this kind of power?

are there cams out there for other platforms that can yield these kid of results?

its only a 5857 about the same size as a 3076 .... 6262 or bigger now that is a different story lol

yes i would agree, a 5857 isnt all that big,especially for a big cam. but it's a bit bigger than a 30r.


IE is being sent a 6262 compliments of a hookup through the speeding-g60 and plan to be testing this with the big cams.

What I see here is either 1 of two things..

(1) the baseline numbers of the test werent accurate

(2) Pete and the boys just pulled a gamechanging hat trick that puts our cylinder heads in major league territory with the B and k series hondas, and the Nissan Sr 20..

anybody want some popcorn?

i am sitting back and watching forsure, good thing i still have a little bit of time until i get back so i can see how it all plays out! yes!

[dubinsincuwereindiapers]

Maybe they did what VAG couldnt even do and designed a set of camshafts to take advantage of the 20v head?? Its possible

anything is!

EDIT: removed false information!

[killa]

Sounds like something i'd throw in my daily driver, when's it going to be available to purchase?

Finally, pictures and more info on the goods.



Matched high rate spring and retainer set. The springs are wound in the states from ultra pure Japanese Kobe spring steel. They are then nano-peened for incredible fatigue resistance. Rates are 240lb/in on the intake, 260 lb/in on the exhaust, .433" max lift- we will probably do a high lift retainer for the all motor guys later if needed.

These have been tested to well past 9k on hydraulic, as mentioned before. We recommend using them with our bigger hydraulic grinds and of course with our mechanical grind when it is released.

Comes with 8 precision wound double exhaust springs, 12 intake springs, and a full set of made in USA titanium retainers.

The cams... Finally available after 18 months of work. These cams are CNC ground on brand new chill cast cores, not regrinds. The profiles are carefully designed to strike a balance between durability and performance, balancing stress and vibration versus opening the valve in the most optimum manner. They have been extensively dyno tested using our in house superflow engine dyno. They feature non adjustable cam gears which have zero bolts to fall out, as well as clear, OE style cam marks for a simple, hassle free installation. A press fit adjuster hub will be coming for those with special circumstances or who really want to adjust their centerline angles.

We have 3 grinds available now for hydraulic lifter. One is similar to a 3658, with slightly more lift on the intake cam, and less lift on the exhaust. The cam performs similarly, with more power under the curve then a 3658. Idle on this is smooth and even with 8-10" typically of vacuum. That cam is called the IECVA1, it is a 270/274 advertised, with .370" / .378" of lift. This grind delivered gains of 97 bhp peak (119 at highest), and is the one we are using in all aggressive street / strip cars. We also tried this grind with a large T4 frame turbocharger and found power to hold strong all the way out to 8800 rpms, so this one can really deliver given a turbo with sufficient breathing ability! That setup yielded 820bhp at only 30psi. If you combine it with a small turbo, like a gt28xx, it will be a waste and the smaller camshafts should be used. We highly suggest combining it with our spring / retainer kit as even on a 600bhp turbo, you need to rev it out to get peak power.

Next is the IECVA2, a milder cam, slightly less duration on both and in particular the intake cam is a good bit smaller. It is more equivalent to a cat cams 3651, a street camshaft for those who prefer more bottom end power and a totally civilized idle. None the less, this cam still delivered gains of 60 bhp peak over the stock cam set.

Finally, we have a drop in intake cam, the IECVA3. A very mild cam which is slightly more aggressive then the Autotech intake cam, this will show absolutely no signs externally or in feeling to being cammed, other then the extra 37 bhp

Dyno charts for all 3... These tests were conducted on a precision 5857 billet dbb turbocharger, mounted on a 2L 20v at 8.5:1 cr. A standalone was used and ignition timing was locked steady for all tests. Water and oil temps were stabilized at 170 degrees F before all runs, and IAT's were set to climb to 120 deg F at the end of each run. Boost was held steady via a 22psi tial spring combo with no boost controller utilized for most stable boost levels.

Is this for real Pete?? Not doubting, it just seems crazy

[derekb727]

These are *not* regrinds, fwiw.

pete you have a PM

[screwball]

What are the medium cams like given the same setup?

[dubinsincuwereindiapers]

Hopefully better thn those junk Cats

[pete@integrated]

We'll be releasing more info as they get closer to release. Been waiting on cores and figuring out stuff for about a year, then we realized to do a really primo job we needed a dyno in house- that was another big delay... Finally been testing them, have a few more tweaks to do, especially to the big grind- the power is obviously there (and we did test the cat 3658 btw, we are making more power across the board)- but I need to work on the civility a little bit.

We test each cam starting at the same water, oil, and air temps. I adjust the AWIC so that the final temp at the end of a run is about the same. We do 3 tests to verify repeatability- we are repeating within about 2hp, then move on.

All of them are using the same exact timing map, which is why I used Q16- so I wouldn't have to worry about re-tuning timing between cams. The fuel map I obviously had to re-tune, but all the pulls are within a quarter point or so of 11.50:1.

They ARE utah corrected numbers- I can't use the uncorrected ones as atmospheric conditions aren't exactly the same from day to day, which would throw the repeatability out the window.

The cores are cast in Europe and ground in the usa.

Here's a cam core before grinding:

No I didnt. Now I did. Haha thanks.

Not as lumpy as I thought they would be but they are more than any other 1.8T cams I have heard. I was down at IE the other day and Pete fired up the dyno and let it warm up to temp. I went outside and Pete showed me the exhaust stack coming out the roof. It has a flapper on the top and it was bouncing up and down. Pete said these were the only cams that made it do that. Once the motor was warmed up he did a pull and it was within a couple HP as that graph above. His testing methods are very repeatable and work great for comparison sake.

BTW I was down there again tonight (picking up my new VR6 Tuscan rods) when we heard someone was saying that these are just regrinds. I told Pete to take a picture of a core, which is what you see above. I hope this puts any rumors about these being re-grinds to rest.

wow!

now i really cant wait to get my 5857 + AEB rolling. to IE!
