    cam upgrade plus pulley what do you think

    I'm an A4 with tsp stage 2.5 5.3 heads tr224/112cam portde fast 90/90. Corrected I put down 417rwhp 407 rwt. In a couple of weeks I'm puttin in a custom cam and specs are 232/236 616 606 111 and a slp pulley. Not positive if I have the lift numbers right,but its around there.What do you guys think I'll put down/gain with this cam and pulley
    Just dropped off the car and the spec are 232/238.8 not 232/236

    20-25 is what I was thinking too. I know I'll lose some down low,but I actually want a little more top end,but did not wan to spin it to 7000rpm just to see gains so this was specced out for me plus it will go well on juice

    the cam degree u posted looks like it may want to be spinning real close to 7000 round 6800-6900. i dont know what year car u have but unless its 01-02 sounds like its time for new rod bolts

    No it wont be quite that high(around 6500maybe 6600) as it was my request. Not only is it on a 111lsa,but it is+2 advance. My car is a 98,but I do have Katech rod bolts in. At one point I wanted to go with an Ms3-4and a bigger stall/gear,but would need to flycut. I think the cam I have will be plenty big. don't get me wrong I loved the tr224/112 for a fast DD/work car,but wanted some more top end and since it was no longer my DD I could put up with less driveability,but I'm sure it wont be a problem for my tuner.
