    any LS2 cam only timeslips?

    any of you LS2 guys have cam only timeslips? I'm curious to see what a cam only setup such as a torquer 2 would do. I'm wondering just what kind of time gains heads will bring. The 243's flow pretty damn good out of the box so the dollar per E.T. gained has the potential to not be very good with heads on the LS2's.

    I'd like to see the before and after time slips of a stock LS2 with stock heads vs. the LS7 GM performance heads........it sounds like you can really boost power for $375, but I'd like to see if there is any gains with everything else being stock.....maybe these heads could be the first mod before a cam swap?

    06 TR GTO~476WHP 425TRQ

    My cam only setup on an LS2 was netting 458/419. Dont know if a FAST 90/90 is considered cam only though. Had the same size cam as the Torquer 2. 1 3/4" Catless LTs, UDP, springs etc. Stock fuel pump, stock injectors(They were at 91%). Without the FAST setup it made 430/397 cam only. It trapped around 119 when I sold it.

    WOW!,,,where are you finding LS7 heads for $375????

    You must be referring to the L92's.

    Ya, gotta be. LS7 heads are what 1200 each vs L92's 375 each.

    my bad, I thought the new GM perfonance heads were the LS7 heads.....their L92 heads still flow a butt load of air for the price

    thanks for the post.....that's the other thing I was wondering about. How much cam the stock LS2's injectors will support. Seems the Torquer 2 is just over the line huh.

    It really just depends on the tune. My tune was a little on the aggresive side. It was still safe, but tuned more for HP than the street(Which was the opposite that I told the guy to do)

    You can have a huge cam on the stock injectors and detune it a little. My buddy are running F14 HL cams in there stock 04 GTOs with the stock injectors running less fuel than me and still making 400WHP with the usual bolt ons.

    You put the T2 Cam with some LS2 heads and stock Ls2 injectors and youll run some 420-440 range numbers with fuel left.

    thats a good trap speed for a na GTO with the mods or lack of, most ive seen only go 113-115 range was it a M6 or A4.
    mods: custom built twins, built 408 w/l92 stock GM heads,GM matching intake,drag bags,frame ties,aluminum drive shaft, performabuilt 4l80e,Yank converter,ohios fastest and quickest 04-06 GTO 9.52 at 144mph. 1.50 60ft on stock rear end and shafts/suspension,on drag radials.

    M6. I was making the power for those traps though. 458/419 was high.
