So I just got my entire car together and tuned (2005 c6 ls2 a4) and while tuning it we discovered the btr stage 2 cam that was bought in 2020 seems to be smaller then stock the way it’s not loping out at all and the way it’s pulling vacuum and the way it’s driving so now I have to do a quick cam swap but I’m unsure of which cam to exactly go with my specs that would matter are
American racing catless 1-7/8 headers
fast 102 intake with 50lb fuel injector clinic injectors
trickflow 225 heads
vigilante 2800 multi disc tourqe converter
Lingenfelter high flow fuel pump
3.42 gears with 4l65e from rpm
Mahle PowerPak Pistons part no (930223270)
Dual btr valve springs
my old cam was a comp cam part no (32734132) but it’s not cut right or something not exactly sure how that would even be possible but here I am lol
btr recommends the “red hot” cam but they don’t site all the specs which idk if I’m exactly a big fan of my tuner recommend the tsp “tsunami v2” but I’m a little worried that’s just to much cam for a car I want to be driveable any input is highly appreciated thank you The kpa my motor is pulling with this supposed stage 2 btr cam The kpa a stock ls2 would pull (don’t mind the crappy spelling for the google search LOL)
I'm not sure if it's too big for your stall or not, but I really love the specs of the summit 8710 cam. 230/242, .625, .605, 113+3. It's probably too big for my 5.7L where the 8707 or smaller would be more appropriate, but in an ls2 with great heads like yours, I think it probably makes sense. Others might recommend the 8707 instead, but I really just like that 230 lobe with the .625 lift. It's a beast but still probably would be tame enough.
Road course it helps to have a wide powerband. Your intake setup flows great, so take advantage of it by going with less needed intake duration. This will create a wide powerband and easily tuned to be driveable on the street with a mild convertor, 3.42 gears and still pull past 6500rpm. It'll be responsive when you hit it from a roll too. Something like the SUM-8707R1 226/238 113+3 .600/.600 or similar (225*-230* intake/235*-240* exhaust, IVC ~ 42*-45* and Overlap < 12*). Great all around cam for your particular combination. And it'll lope really nice too.
