How much faster if you jack up the front end?
Got another question, after purging my car sat there and sucked up all the coolant from the overflow. Would I have to purge again if air got sucked back in the radiator? Or good to go w/ just one purging?
Had to purge again but this time I put extra coolant in the overflow in case it sucks it back again. The only problem with this new funnel is the cap that goes on the radiator doesn't have a gasket so I had alot of coolant/water leaking from the cap, which is probably why I had to add so much since it was leaking out alot off the top. Did the same happen to you Sharif? Probaly have to put some sort of gasket to make it a spill free funnel kit. In any case this info was very useful. thanks!

Several people on the forums use these type of funnels, so maybe they can comment if they made any mods to their spill funnel.
My spill funnel makes 27whp without tuning..BTW.

I think it's because the cap that goes on the radiator doesn't have a gasket on mine. Does anyone elses leak off the cap like mine, just seeing what others did if so. I just got a rubber washer to try to make a tight seal so going to try again later today.
Finally no more over heating issues since there hasn't been any post people must of solved their problems as well. I got the coolant bypass mod, upgraded PWR radiator, GTM Fan upgrade, and Nismo thermostat. No more coolant squirting out the overflow and no heat issues when I get it. Allows me to run Lo and Hi boost no problem. Just wanted to say thanks for the advice of many members here.

And the reason why my non spill funnel was spilling is because the pressure from my overflow was pushing coolant off the top, so the non spill funnel works proper now.
