What do you think of this cam
What do you think of this cam Patriots - 232/230 Dur. @.050 .580"/.580" Lift 110 LSA
I am inthe market for one, and from the reading I have done so far this seems to be a reasonable choice. I have a 99 A4. No emissions and its a daily driver. I will have a stall in the future, but decided to get the cam first. Is there anything bad or problems you guys might see with this grind? Thanks

Take the exhaust and intake durations and add them together.
244+248 = 492
Take the sum (492) and divide by 2.
492 / 2 = 246
So now that you have the avg of the two combined.
Take the LSA without the advance (be it +0 +2 +4...ect) and double it.
115 x 2 = 230
Take 246 from the avg of the durations and subtract the LSA x 2.
246-230 = 16
My cam is very choppy and it is caused from the extreme 16+ degrees of valve overlap. The stock cam has like 17-22 degrees of negative overlap (I don't have the specs of a stock cam in front of me otherwise I could tell ya what it is), so you will not hear the time between the valves opening and closing as easily. Granted it is there, just not near as drastic.

Verdad Gallardo haha nice work... i didnt mean it would sound exactly like an ms4 but... with a 110 its still gunna have a nice plop too it, i have a 112 (even though its a 233/239) and mine is very lopey.... im gunna use that formula however... and the stock cam i think is something like 200/202 duration and like..... 119 LSA
just because a cam cas a 110 lsa does noty mean it will lobe very hard, a 224/224 on a 110 has 4* of overlap a 236/236 on a 110 has 16* and say a 220/220 on 110 has 0*
idle speed also has an effect on the lode.
the cam you said 232/230 has 11* a 3k+ stall would help alot and 11* is not that hard tyo get to idle niceley
idle speed also has an effect on the lode.

I ordered that cam, but patriot stoped making it, so i got the 226/226 cam,
btw.. i must say it has to be one of the best sounding cam i've heard,
but thats maybe only because its sounds like the big cam i wanted

I hear you guys about the stall. I will be getting one eventually. Im trying to hold off on that until my tranny goes so I can build the tranny and put the stall all in at the same time.
By using this cam I was hopeing that it would be small enough that I could get away with a stock stall for a little while. Though I dont really want a stall, I do realize that it is just about a necessity for a cammed car.

244/248 .598/.598 115
Take the exhaust and intake durations and add them together.
244+248 = 492

492 / 2 = 246
So now that you have the avg of the two combined.
Take the LSA without the advance (be it +0 +2 +4...ect) and double it.
115 x 2 = 230
Take 246 from the avg of the durations and subtract the LSA x 2.
246-230 = 16
