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?

 

Another vote for the 114.

 

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.
Tuning is the name of the game

 

You got that backwards, 112 lower peak, 114 higher peak.

But 114 is better daily driver cam

 

You beat me to it

 

you have those backwards..

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.

 

Why not go 110 for all the same reasons? That is only 8* overlap.

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

 

Get a converter first

 

Ive got a TR224/112.When I first got it istalled it died alot and had lots of problems.Took my car to a better tuner he had it all fixed within a couple of hours.Starts right up never dies idles great as a matter of fact hes a memeber here his name is marc(98redorangeta).I would do the stall first before i put that cam in though just my opinion

 

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

 

Answer this question:

Who will be tuning your car, and what software will they be using?

That's gonna make the biggest difference with this mod...

 

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??

 

thanks for correcting me, as u can see on my post it was 3:40am...I was tired.

 

VIG 3200 or Yank ss3600

 

Took the words out of my mouth. Great recommendations.

 

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.

My A4 runs a 2800 stall. A loose converter will likely up your gas bill a bit, but is actually a driveability improver for a DD. I have run higher stalls but find 2800-3200 a pretty good compromise for a street driver with minor mods.

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.
