Measured the BC 264 cams: Intake: Journals: 26.96mm .92 .90 .92 .93 .91 .92 Lobes: 39.20 .22 .21 .22 .21 .19 .21 .19 .20 .19 .21 .19 Exhaust: Journals: 26.98 .93 .93 .92 .93 .92 .92 Lobes: 39.22 .22 .23 .23 .22 .21 .20 .20 .20 .20 .19 .19

Just surfing the forums & came across this interesting data.

The lobe seperation angle on these cams is 114 if installed at 0 & 0. Try these combinations: Ex +4 only 112 I+4 E+6 113 I+6 E+4 115

Andrew As you have been running the cams for a few weeks & are going to install another adjustable cam wheel it might be a good idea to take pictures of the #1 journals to see if there is any unusual wear & check how wide your grooves are. I dont think mine are a one of, unfortunately.:nono...

Second attempt. http://www.supramania.com/forums/attachment.php?attachmentid=18184&stc=1&d=1194354862 http://www.supramania.com/forums/attachment.php?attachmentid=18185&stc=1&d=1194354862 http://www.supramania.com/forums/attachment.php?attachmentid=18186&stc=1&d=1194354862

Received the cams today. The oil groove on intake journal #1 is around 7mm compared to 4mm on the Toyota one & both #1 oil supply holes are mostly blocked. The exhaust is around 4mm wide.

Just took my car out to clear out the cobwebs (again).:aigo: Under wot in 2nd it changes around 5,800 in normal mode and 6,200 under power mode. Will definately have to install new valve springs :cry: to take advantage of the extra revs the new cams will pull :biglaugh: as the old ones are...

I really wonder how much research & development went into getting the cam timing right? I know all engines are different to a degree but it should not take a lot of fiddling with both the intake & exhaust timing, unless you have done a lot of modification & machining. The BC timing tag shows...

Is it just me or does that timing card diagram seem wrong to anyone else?:aigo: @0.05" lift: The total inlet duration is 220 (180 + 40) The total exhaust should be 236 (180 + 48 +8) ie opens 48 BBDC & closes 8 after TDC giving 8 degrees of overlap.

Well I think using the term valve lift is a bit confusing as the 7M engines use overhead cams so the valves actually fall not rise when they come of the seat. There isnt a lot of room to place the dial gauge on the bucket or shim but the way I see it you would have to preload the gauge to...

Sounds like your fan belt is too loose. Tighten it a bit & see if the noise dissapears.

Did you put in new camshaft seals & install them properly? You need to put some sealant in four areas around cam bearing #1 otherwise it will leak oil there sooner or later. I would not disturb the head as I believe your problem is coming from towards the top of the head area. Take of the...

Have you received those BC 272 cams yet? Do you think you will get into the 130 RWKW range with them?

Has anyone dynoed their car with the 264 or 272 cams for the 7M engine? Surely there must have been enough sold & fitted that someone has a chart?

Obviously some of you guys are misreading my question. All I want to know is how well the n/a 7MGE engine goes when you install the turbo intake cam in it. Will it suffer from loosing too much torque down low compared to the extra power up top. Could always advance it a few degrees to...

Just after some feedback from anyone that has tried the turbo intake cam in the n/a engine. Has slighly more lift & longer duration so should give a mild top end increase.

I would just like to know the opening & closing values of the valves @50 thou lift for my current cams. Already determined that my crank TDC mark is not accurate. Have a adjustable cam gear on the intake so can vary the timing there to determine the best position for maximum bhp. Could get it...

Has anyone done this with the engine (7M) in the car? What are the steps involved?

Does altering the ignition timing setting affect the exhaust cam only or both the intake & exhaust?

So has anybody done a dyno readout with either the BC264 or 272 cams installed so we can see where the improvements are? Hopefully 264 in a 7MGE would be great.
