450rwhp what size injectors?
Will my stock '02 injectors hold up to 450rwhp NA? I plan on spraying down the road, but it will be a wet direct port kit. What is the cut off on stock injectors before the are maxed out? What size should I run if I need to change?

I can tell you that my Z06 is at that hp level already and the stock injectors are at 105%. I think some 32 lb injectors would be a safer choice.

With a stout 450 hp get some MSD/Holley 50's or Motron 60's! They are a better injector compared to the disc style 42.5 009's! And of course see if your tuner can tune for them first! But I say go big and tune! Both of these injectors perform really well at low duty cycle.

If you are at 450 whp , go #42's or at least #30's . #30's will max before 500 whp so at least with the #42's you will have some room . Lucas and SVO are the same to tune with , I have never noticed a difference in the LS1 on these at this flowrate .

Who has the best deal on a set of 42# quality injectors? I read some bad stuff about the racetronix disc style, should I avoid them?
Are these any good? http://cgi.ebay.com/ebaymotors/8-Bos...QQcmdZViewItem

I got my 60's idling good but I think that they are causing a very annoying surge in the 1800-2200 RPM at 3-6% Throttle position. I am trying to find someone to swap them for some 42 SVO's. Unless you are gonna go FI or a huge dryshot, you will not likely ever have a need for 60's.
