Had a cam made....

[RedneckRicer]

i was getting the head redone on my accord and the guy at the machine shop mentioned that he had a place that would do a performance regrind for 80 bucks, which seemed really reasonable after reading the posts here, after it came back ( i get the head back saturday ) i called in and asked for specs on the cam, and he came back telling me the following....

Intake lift .263
Exhaust Lift .276
Intake Dur. 262
Exhaust Dur. 272
Lobe Separation 114 degrees
Overlap 69 Degrees

after reading the specs off the board for the colt cams, and stock specs this grind seems fubared or really really low


INT: 260° .384 Lift
INT: 270° .384 Lift
EX: 274° .402 Lift

given this is the TRI-FLOW Grind from colt, the lift seems way low on mine... am i right here?

[3G Jester]

maybe the place that did it just doesnt know the best way to grind it....or maybe they havent reached the 'edge of the envelope' yet....ex:
INT: 260° .384 Lift
INT: 270° .384 Lift
EX: 274° .402 Lift

Talk to the shop and try to get the same specs as the colt cam or just get the colt tri-flow.
Hey RedneckRicer do you live in P-town or in Escata. I don't see a redneck living in P-town, maybe Molloa.

[RedneckRicer]

i live just outta oregon City, lol, there was another thread on the site claiming that the stock lift was also in the .300's that what kinda worried me, ya know? oh yeah, and the cam is already ground and they're going to put it in the head and adjust the valves, so i can be lazy and just bolt it on, so i'm stuck with the cam as it is...

[Justin86]

Well that sucks.

[RedneckRicer]

i guess at best it might have a little more than stock or at worst i got shafted outta 80 bucks, which really bites the ol' bean bag

[Gregg86DX]

Hey, I am just outside O.C. too! I am out toward Beavercreek.

Anyway, that looks like a standard grind from Delta Cams up in Tacoma, except they told you the wrong lift specs.

I would not get too worried, it's far more likely you got a typo than a bad grind.

Did you see the actual tag from the cam?

[RedneckRicer]

i haven't seen the paper for the specs myself, so there still may be hope, lol. but it was clackamas auto that's been doing the machine work, though i don't know the name of the place they send the cam to. its supposed to be done about now, but because of work, it might be as late as monday until i can get it home

too bad i can't get all my crap together sooner and make it to that meet tomorrow, but i have a feeling my boss is gonna dick me outta having saturday off anyways

[RedneckRicer]

well i picked everything up yesterday and talked to the guy in the machine shop, the lift figures they gave me were cam lift and not valve lift, he didn't know the ratio for cam to rocker, but said that for honda's is in between 1.5-1.6 so the actual valve lift is somewhere around these...

Intake - .394 up to .420
exhaust .414 up to .441


so if our ratio is within those parameters the cam is actually might have some balls! It was done by a company called " Redline Cams " but the machinst told me they like to tinker with motors and have even stroked out a 22R (2.4L standard motor in older toyota pickups and cars) to a 2.9L so as soon as i get my car together and test this cam out, it might me a nice alternative for some of us around here? all in all it was 60 dollars to have the cam done, so its pretty cheap, and didn't take long, it left the machine shop on a thursday and cam back the following tuesday.

[shepherd79]

ok so will you be able to get group buy?

[RedneckRicer]

actually if you go to clackamas auto in oregon city, they will make you one, i don't know if there would be a discount for getting a bunch made, but this would be easy enough to have them done one by one. btw, does any body know what that ratio is for the A20?

[Justin86]

So have you put it in and gone for a drive yet.

[RedneckRicer]

well i spent a good part of the day working on it only to get the shaft by a spark plug, it won't thread in, its midnight and there's no auto parts stores that are reasonably close.... so it'll be tomorrow after i get a tap and clean out the threads..... i didn't cross thread it, but the threads are all fubared hopefully not bad enough to warrant a heli-coil

[Justin86]

Yea that sucks. Hope it all works.

[RedneckRicer]

well i tapped the spark plug hole, got the plug in, and now it won't fire, it turns over and over but just won't fire. anybody have ideas?

Check for spark. Pull a plug and ground the tip while someone cranks the car and see if you get any spark.

If you got spark, use some starting fluid to check for fuel. If it won't fire with starting fluid, then make sure your cam timing is correct.

[RedneckRicer]

it has spark and fuel, but i'm wondering if my cam is 180 degrees out, i'm stopping for a few minutes for food but then i'm back out to check the timing, i talked to a guy from a shop and he said that the tensioner adjusting will sometimes cause the belt to slip a tooth when you put on a new belt, which i did, so i that might be a problem too. my intake manifold also makes kind of a light hiss when you turn the ignition on but don't start the car, i didn't notice it before, but that doesn't mean it wasn't there, does anyone else have a 3g that does that?

[funkytuqe]

Yah, maybe you installed the dizzy 180' out, make sure the roter is pointing to cyl #1 at TDC

[Gregg86DX]

Are you sure about the fuel? Your car is injected, so it's kinda hard to tell. If your sure about spark, then try the starting fluid. That will tell you right away if it's fuel or something mechanical like the cam or distributor off. I don't think being one tooth off would prevent the car from firing, but it would probably not run right.

The tab that drives the distributor off the cam is offset so it won't fit 180 degrees out of phase.

[RedneckRicer]

the cam was 180 out i lined it up on the exhaust stroke of the #1 cylinder at TDC, but now that i have it running the thing is just plain slow, i don't wanna wind it way out but the power band is insanely gone, lol

[dXsquared]

hmm.. check fuel pressure, timing, check for fouled plugs, check for ECU codes, vac leaks, fuel filters and PCV valve... if all that is OK, then maybe the guy fucked up your cam?

Travis

[3G Jester]

recheck the install..maybe take it apart and reinstall the cam....did you mess up a valve or two puting it in? are your valve springs all good?
travis does raise a valid point. the cam regrind did seem odd in compparison to the colt cam regrinds.....maybe he did fuck it up. if all else fails go get a J/y cam for 10 bucks and try the stock cam vs the regrind. if there is a diffference then you got fucked over. if not then its something else. thats the only way to test it i figure.

[Justin86]

I would do what Jester said get stock cam. I have an extra but I don't plan on going up to P-town in the near future. My mom is going up this friday though to Wilsonville.

So was the distributor off 180 degrees relative to the cam or was the cam off 180 degrees relative to the crank?
