Mallard Posted November 9, 2009 Report Share Posted November 9, 2009 No need to get defensive. I know what your car made before. I used to see it at the track way back then. I'm just saying that it seems like everyone and their brother is knocking blower cars lately and it makes me laugh. I would have liked to have ridden in your car before it blew to see how it felt in comparison to some of the other blower cars running around. I guess I'll have to wait for the built version of it Not trying to knock s/c cars, but if I would go S/C I would use a KB or Eaton TVS. Centrifugal S/C don't make sense to me unless it's in a FWD setup where you might want power to build progressively for torque steer or traction reasons. If the turbo is properly sized you should be back at full boost after a shift at redline. Hopefully you're gearing's not so high that a shift puts you back under the boost threshold.

BDHG940 Posted November 9, 2009 Report Share Posted November 9, 2009 Turbo cars from what I've seen always have impressive trap speed but don't et that well in stick cars anyway. I think I'll stick with a blower on mine for that reason. my car was on just over 1psi more when it blew up and was done just at the 1000' mark. I trapped almost 3mph faster than the best with my Novi2k and 2/10th's faster. Not trying to stir it up I just dont think that is completely true Quote Link to comment Share on other sites More sharing options...

Im with you completely on that one, I loved the way the Magnuson made power on my old TBSS compared to how the Cobra made boost with the Novi2k. Neither of my 4.6 cars have issues staying in boost after shifts, its pretty much always there Quote Link to comment Share on other sites More sharing options...
86GT Posted November 10, 2009 Report Share Posted November 10, 2009 I would say both combos have their advantages. I like being the underdog so i will stay with my blower. Turbos definatley make good power i'm just more of a blower kind of guy. Quote Link to comment Share on other sites More sharing options...
mitchsY2kGT Posted November 10, 2009 Report Share Posted November 10, 2009 That little 86 GT is NASTY FAST!!!!! Hope to see in the 9s soon..... Quote Link to comment Share on other sites More sharing options...
DKilbourne Posted November 10, 2009 Report Share Posted November 10, 2009 That little 86 GT is NASTY FAST!!!!! Hope to see in the 9s soon..... If he goes with the bigger blower, he'll be doing that next year. Quote Link to comment Share on other sites More sharing options...
86GT Posted November 11, 2009 Report Share Posted November 11, 2009 If all goes well at work over the winter i would like to upgrade to a Ysi and crank the boost up. If this happens I would like to go deep into the nines and still be a stick:D Now back to the thread at hand lol. Quote Link to comment Share on other sites More sharing options...

Guest GMoney Posted December 7, 2009 Report Share Posted December 7, 2009 Turbos are flat out more efficient at making power. How do you say that you would rather have a centrifugal S/C over a turbo? I would own a roots style S/C or turbo, never a centrifugal S/C and on top of that the only reason to ever run a roots blower over a turbo is for that instant low end punch. To say a turbo car at a lower psi than a blower setup puts more stress on a connecting rod is just crazy. Turbos use HP to make HP just as S/C, just in a different way. One is driven off the crank and one is driven using back pressure. Both put different stresses on the motor and have different affects. But flat out if both the S/C and turbo are sized properly the turbo setup will make more HP and more torque at the same boost levels. Also as mallard stated look at the area under the curve... That is the usable power. Quote Link to comment Share on other sites More sharing options...
DKilbourne Posted December 8, 2009 Report Share Posted December 8, 2009 I guess 86GT should just give up and put a turbo on the car then. You heard it here first. What the hell were you thinking putting that Vortech on the car? Quote Link to comment Share on other sites More sharing options...
