TSP225 or TSP228R for A4?? Buying one of the two very soon, just thought id get your inputs. Car is a bolt on 98 A4 car. Im running a TCI SSF3500 stall and stock 3.23 gears in the rear 10bolt. What would be a better street cam? driveability? gas mileage? They are both running a 112lsa, very similar lift. the 225 is actually a TINY bit higher with a .589 verses the .588 of the 228, but obviously has a bit more duration. What do you guys think?

I have the 228r and went 7.3 with it. No weight reduction to speak of. It is a nice cam but I've debated dropping down to the 225 to see if it has better low end torque.

If the lift is the same with different durations, one probably has less aggressive ramps. The 228 might actually be a "smaller" cam than 225, depending on the ramps. Check duration at .200 to find the real story.

He did a lot of searchin on cams before he got that one. Matched them to the heads and damn that thing put down the power and showed it. I am running that cam on a 114lsa and i am running the same times i was with the g5 but it is also a lot hotter now like 30+.
I wander what happend to those heads. Anyone on this board buy them. Just want to get the flow numbers.

The higher the Duration the more loss on the 2000>4000 trq #'s which is where you are at on the street.
So for more "Peak" 228R
For more street torq 225.

I liked the TSP 228R cam.. I thought it was very streetable.. That really depends on your idea of streetability however.. If you're going for an aftermarket cam gas consumption shouldn't be one of your major concerns.. 
If I was in your shoes, I'd go with the 228R and some 3.73s.. That should make for a fun setup with that converter..
Good Luck
