great numbers, is the meth injected directly into the side of the plenum vs the intake pipe?
sharif, did he have to relocate the wastegates on the greddy tt to run that much boost?
Are the 18g's running out of its efficency range?
Thanks for the comments, guys.

Great numbers Sharif. Quick question though, what is the power range that you would insist on sleeving a block on a daily driver? I am looking into engine packages and wanted to stay in the 550 - 600 whp range on a daily basis on 93 octane and thought that a sleeved block would be required but from the mods list, this block is not sleeved. Anyone else can voice there opinion as well.
Thanks,
Mike

My personal opinion, is that the limits of the stock sleeves will exceed the limits of the current crop of TT kits on the market at about 600-700whp, but only time will tell. The stock sleeves have some definate cooling advantages as well, particularly for those that road race/track day their cars.
Very nice post. Nice to see you backing the unsleeved motors. IMHO, the extra heat, machine work, cost, and risk of sinking with sleeving this motor just isn't worth it. At least not until we start seeing motors failing because of a compromised cylinder wall

I think the consensus is that his car wasn't as 'bad-@ss' as first thought. SP numbers don't hold much clout around these parts any more
And in regards to the numbers at hand -> 600+ = pure insanity.... congrats
