I found this information from a French magazine (Auto Hebdo #422, 1984) that tested a 505 with Peugeot-Talbot Sport "kit 200 ch" (or "kit 200 hp").

Diagram (cam 200 hp):

AOA: 28°

RFA: 76°

AOE: 82°

RFE: 22°

Valve lift: 10 mm

Diagram (stock N9T cam):

AOA: 19°34

RFA: 56°26

AOE: 55°10

RFE: 12°50

Values for stock cam are almost the same that are listed in the first message. Only RFA is 56°26 vs. 56°24. Typo in the magazine or in the message?

But what about the "kit 200 hp" cam which should be the Danielson cam or do we have another different cam profile? I know those values in the first message are directly from Politecnic but I don't know how that French magazine got theirs.

interesting, the values in the first message i think were posted to Peugeot-L by a member (i forget who) who got a cam from politecnic, and had it checked.

hmm, it actually looks like those are specs from V-M! :huh:

And others I collected from Chrysler repair manuals. :huh:

At what lift is that duration measured? 0.050"?

I have not verified by measuring my self, but my understanding is at usually all European manufacturers inform with 0 lift and separately state if there is 0.05" lift results.

Ok, can a cam-grinder regrind a std-cam based on these specs?

Approximately how much would it cost?

the cam on the project 505turbo.com is using a reground stock cam to the danielson specs above. it was pretty reasonable from a known good regrinder. about $150 USD

That sounds really cheap to me. :P

Did you give the grinder the specs above or did he have "his own"?

I asked a known cam-grinding company in sweden, Enem how much it would cost to grind a std cam to the specs above, but the guy couldn't tell how much it would cost just based on the specs above.

If u need one, I can help. I can provide ready package or u can sent your current one to me or directly to grinder. Then of cause sending cost's are nearly same as grinding but just if u need help.

I have special grinding model for dani cam (making model cost's same as grinding cam -> 80€) and there is one model in grinder which have bit milder but have more lift (I have used both). Also I have (original) new set's of rockers.

i've also thought of going with a slightly milder cam profile (somewhere between stock and danielson). how did it work V-M?

Thank you!

I really appreciate the offer.

I will not be re-grinding my cam until in the summer or so though.

I'll try and get someone to grind it for me here in sweden, but if anything else fails, I'll send you a pm.

Johnny, i want a cam regrinded too, maybe we can kill two birds with one stone and do it together? We might get it cheaper then! Think Enem are so damn expensive, last time i talked to them they wanted 275Euros :)

And that was a few years ago!

Or perhaps V-M can help us?! :)

Cant cost that much to send a cam to Finland and back!

Im from Gotland. Not too many grinders here in sweden that knows how to grind turbocams, i have talked to a few but they didnt want to do it. Think the shipping to Finland comes to about 300sek (cant remember how much a cam weighs).

I will search around some more after grinders, but i think Finland is a good option.

I would guess that the grinding price depends on if they have a model to grind after, just as V-M says!

Talked to another dude who said that it cost about 1200sek at enem! I would really prefer to get a straight answer from enem, but they are so big that they probably dont care about us small time tuners...

I think I have translated the letters in the first post.

AOA = Opening of intake BTDC

RFA = Closing of intake ABDC

AOE = Opening of exhaust BBDC

RFE = Closing of exhaust ATDC

Croisement = Overlap

Assuming the lobes are symmetrical, I calculated the lobe separation to 121.5 degrees, could this be correct?

I think your translation is ok, I'd just like to know one thing:

What does BTDC, ABDC, BBDC and ATDC mean?? :P (sorry if it's obvious)
