thank you. now please give them those links. and teach them how to search.
the t-rex has been beaten to death in here. the answers you search for are out there. its not a gentle cam, you'll need a big stall, and gears to tame it. not to mention a tune and most supporting mods(ie full boltons - or close to it).

So did I? search and found. But good luck on the install I heard on autos cant run the Ac with out some problems with it cutting off. Tune it to work with the ac but you get some power loss. I heard this from guy at thunder itself. hope you never run the ac in traffic or in the city only hway. or take it off.

better go higher than that.
I have 4.10s in my auto... i love em... with a 4000 stall... with the T-rex driving in traffic will be easier the more gear you have (higher numerically)
4.30s wouldnt be a bad idea

There is a cure however, but it is very costly, but if you want to be RAD.
Independent TBs and SD tuning will make this cam purrrr like a kitten.
Harrop racing in Aussie land specialises in that.
I ran it with my A4, no problem once I tuned it, which takes alot of patience and time (for me anyway). It only surged a tiny bit in reverse, otherwise ran great. I stayed with my 3.23 gears and a 4K stall, although 4.10's would of been better if you don't run N20. The trick to run a big cam in an auto with the stock gears is knowing how to tune the tranny shift points for part throttle and lock up. It is a pretty big cam for a DD though and plan to spend some time in the 7K plus RPM to take advantage of the Trex as well. I did 430 RWHP with out the FAST 90/90 setup. Unfortunately, I'm almost an M6 car now and will never know what improvement that would of added..
