Combo Equation need to be solve heey guys..
im gonna order a TSP 228R this week,,
im just wondering about the lobe sep. should i get 112 or 114 ??and why??
and what is the difference " idle/driveability" ?? "im a beginner in internal"
NOTE:
im a DD and the car is 99 A4 not stalled full bolt-ons + 3.73 gear..
The equation is :matching the 228R with the stall and the 3.73 gear +the nitrous ,, for the best result in street racing and some 1/4s
thanks in advance

IMO go with a 114 on an auto, even tho there isn't too much of a difference in those lob seperations on a 114, being a DD and an auto I think it would be the best choice.
112 will add a higher rpm peak on hp/tq but with a nice lope at idle
114 will add more in the lower/mid hp/tq with a closer to stock idle and is easier DD cam
I'm sure there is more I'm missing, I know there are many with autos running a 112 cam on a DD/auto so anyone want to prove me wrong?

Cam only I would choose 112 for better DCR, more overlap and better power. With todays tuning tech, a 228 112LSA is only +4* verlap which is nothing scary. I run an A4 and my cam has 7* overlap and good DD.

But 114 is better daily driver cam

i vote for a 110+0 lsa. will give more low/mid range torque, a sooner peak, and the ability to carry peak power futher.

Seems to me tighter LSA is better for street power, wide is fine if you are building a track machine with high stall speeds and higher numerical gear ratios (i.e. torque is not as important)
Would 110 LSA and the resulting 8* overlap work with the stock stall in a DD?

I think that's way to big for a stock stall. A 3200 rpm Stall Converter with out the cam would be faster in the 1/4 mile, and better to drive, then the stock stall with the 228R you want. Always match cam and stall converter.

Another vote for 110LSA, but add at least 2 degrees of advance...more for automatics, +4 is even better. Dynamic compression will be higher and power under the curve will be better

thanks for your reply guys, its all really helpful..
i think that im gonna have the 114 for the driveability..
but what stall converter you think match with this cam + 3.73 gear??
and dont forget that im a daily driver

it will be a dyno tuning with EFI-live on a local shop in my country
and forget to mention that i spray 100 with a wet TNT F2..
so i wanna match the 228R with the stall and gears + the nitrous "daily driver"
any body can solve this equation??

Why don't you listen to Patrick's idle clip. If you will be happy with that kind of idle tighten the lsa to 110 or get the 112. If you drive a lot in traffic and value the driveability of the stock car than buy the 114 which can be tuned to drive darn near like stock.
If 80+% of your time in the car is spent in traffic, I would not hesitate to get the 114 lsa. If you keep your car in the garage most of the time until you head for the dragstrip or occasionally drive 5 miles with no traffic lights to work get the 110. Only you can answer those questions since you know how you use the car.
The 110 will be better at the track, the 114 on the street. That is clear. How much you want to make compromises for either is up to you.

I also have a cam on a 114 and it is a wonderful DD. My 402 has a big cam on a 112 and it is not nearly as much fun to drive to work. Well until a big hole in traffic appears that is.
