i made this list and will continually edit when i find new information. please let me know if i have any of the info wrong. or if you have comments about a particular cam; idle, power, etc. thanks.

according to Crane the stock specs are:
Stock
Advertise Duration: Int=222 / Exh=224
Duration @ .050: Int=194 / Exh=196
Lobe Separation: 110
Gross lift: 333/362

Rocker Arm Ratio
I 1.63/E 1.87

im not too sure how accurate these are though. because when i measured the cam lift in the 88 pm3 that i am porting using their rocker arm ratios the lift at the valve would be 380-384 intake and 372-376 exhaust. which is about the same as there 251-0010 cam. the cam i measured is from an 88 civic wagon 4wd, so i dont know if i have a special stock cam or if crane is taking on gude's business practices and lying about stock stuff so theirs looks alot better? i didn't have an accurate way to measure duration though since the head was off the block. i made a 720 degree timing wheel (crank turns 2 to 1 to cam) to use on the head but i got sick of screwing with it.

in no particular order -

the 'tech guy' said that the 260 was designed to be just a stock replacement without having too many aftermarket bolt-ons, where the 272 works better with modifications.

also the 260 out-accelerates the 272 till ~3500rpm where the 272 out-performs.

Good Work!

fastcrxsi90

anybody know the specs for the jg 301x? or if anybody else makes cams for the A6?

fastcrxsi90

edit on delta 260 profile. and added stock specs. still looking for info on the jg though.

CRX Lee

Thanks for gathering the data, I've just started investigating options on the D16A6 this week. In my new race class I am a allowed max. .390 lift with no statement about duration.

If anyone has any hands on input, I am interested as this is my first tun into a class that allows anything but a stock cam. I have been told to lean more toward the Crane or Web options although the Web only has .376 lift. Idle doesn't matter at all to me on this track car as long as it starts, and upper rev range of probably 4000 to 8000 is all I care about. Any guidance is appreciated.

yoshi234

I had the Gude 2624 in my old 91 Si. Along w/ the cam, I had Superchips ECU (their standard program), Lightspeed header and HKS cat-back.

The Si felt like it had vtec, as when I hit ~4K rpms the engine would just scream to 8K at which point I would shift. This was on stock valve springs, as Bill Gude assured me it would be fine.

If I had a D16A6, I'd go this route again since I still have the cam and ECU.

yshi - who won't be going this route as he just bought a ZC on saturday

Steve91

One nice thing about this is you can take any of these measurements, send the cam to Delta, and they will grind it to that spec for $65.

It would be nice if you had lobe separation on their as well.

fastcrxsi90

Crane is the only ones who like to give out any info on their cams. they have the spec cards like this that are very useful. it even gives all the valve timing events like ivo, ivc, evo, evc, etc. http://dab7.cranecams.com/SpecCard/D...1=Display+Card
just type in the part number ive given for the cam in this page http://www.cranecams.com/spectest.htm.

everyplace else just gives the advertised duration and lift at valve. and then they say the power band is here. thats all fine but it makes comparing cams a bitch.

like if you compare the delta 260 profile and the gude gorilla jr. both have close to 260 duration and about 400 lift. but delta says its a mild street cam for if you have no modifications. where gude says you need headwork, gude ecu and the power band is from 5000-8600. so wtf? i dont know whats what with this?

dtcrx89

Well, I've dealt with Bill from Gude. He will try to upsell you any chance he gets. nothing seems to be good enough unless you add their head package. Just my two sense on Gude.

CrxSi707

Has anyone heard of Gude's 26824 cam for the D16a6. I have a buddy who has that cam (bought it years ago) and it is alot more powerful than my Gude 2624 cam. Although Bill won't make it anymore for some unknown reason.

altoid

wil from exospeed told me the race cam was 268 duration with 398 lft or something like that (i and e)

I used to have the specs on my JG 1001 cam on a web site...but I can't find the damn thing now, but I'll keep looking. Awesome list by the way!

CRX Lee

I think I am going to order the Crane 250-0012 next week as it fits the edge of my race class rules. Anyone have experience with this cam or know a reason not to do it?

fastcrxsi90

if you want to save a couple hundred dollars call delta and see if they can grind that cam for you. their 260 cam has .400 lift, so maybe they can change it to suit your needs. 1-800-562-5500.
i might try their 260 grind. the 272 just seems way too overboard when you compare it to others. the 260 is almost the same as the exospeed cam. but then again i keep changing my mind so i dont know if ill ever decide!

SmobbinSi

Bri, I can't believe you remem that cam grind number!!! I need to find that spec card that came with that cam so we can have it remade from a billet.

That cam from Gude is the sheeiiit though, the idle is stock, put it straight pulls from 4k to the limiter...

CrxSi707

E, call Bill and see if he'll give you the specs or maybe even cut some more.....

SmobbinSi

Just talked to Bill...he was wondering how in the hell I got that grind! He says he only made 3 of them, one for his own personal use on his h/b. He was kinda impressed that I ran 14.82@93 without his head package. Told him I had a stock clutch, i/m, and t/b too.

He says that the 26824 is better for a stock ecu than the 2624, and he is thinking about reintroducing the 26824 again. Could you believe he invited me down to pull the cam out so he can take a look at it, that's hella crazy. He is willing to make more grinds for $295 with core, and a 2 day turnaround.

The specs are as follows:

intake lift .425 duration 228 valve clearance 6
exhaust lift .383 duration 225 valve clearance 8

CRX Lee

I called Delta today. After talking with the HART folks, they like that the Delta cam has the most duration without too much lift since I am limited to .390 lift by the rules. Delta said they could fudge their .400 down to .390 so for only $70 and a used spare cam to lose, I think I'll go that way first. It is so cheap compared the other other options that it seems odd but it isn't that much money to risk if it doesn't work out. I'm going to send a used cam out to them this week.

Bill is funny. He used to try to tell me back in 95/96 that he had a special HONDA hig compression cast racing piston for the A6. What did he think I was.. a big idiot? And he was charging $400-500 for these A1 pistons and said that it was a super good deal. Sorry but to Bill. Thats why we decided to do our R&D on the A6. and all our research payed off well.
13.6@99mph. stock block, no mill, 35mpg. jus head work and our own special cam

JaeOne3345

best sohc post ever. its good to see some guys actually going deeper with sohc then just intake header exhaust info.

SmobbinSi

Yeah Bill is kinda funny, he couldn't even believe that the cam I got from him helped my car sooo much. I'm pretty impressed with your ET/trap...you mind PMing me your set up? BTW I hit my 14.82@93 on an 200,000+ mile d16a6 and the car was on street tires with the only weight reduction being my pass seat, spare, and rear compartment full of junk. The funny part is before I wrecked it, the car was still hitting a 15.0@91 with over 280,000 miles!!!

ExospeedAMcrx

Until I retired the motor, it hit the 13.6 the last month I drove it, the same as when it was just built. That is after more than 100K miles on the block... Im sure I've revved that thing to 8grand more than a thousand times.(with those puny d16 rods ).

The setup? 13.6@99mph. stock block, no mill, 35mpg. Exospeed Head package and our own special cam.


[Modified by exospeedAMcrx, 3:38 AM 3/8/2003]

SmobbinSi

Thanks for the response, but I have a few more specific questions:

Did you use slicks or street tires? What did you do in terms of weight reduction(how much did your car weigh)? Does your head package include work being done to the i/m and t/b? What kind of clutch were you running? And what ECU?

sporkcrx

Slicks, and 1500lbs. Don't forget about the tranny too.
