I recently purchased a 97 lude with a bit of mods and has been dynoed at about 240 crank hp and 187 whp. This is with the stock injectors in, but i have 330 cc injectors just sitting around and was wondering if they would make much of a difference in the performance. I have an APEXI fuel computer as well- will new injectors effect this at all? All info is greatly appretiated!

 

It depends on if you fuel system is maxing out, Is this an OBDI or II setup? you have to make sure you have the right resistance for your injectors for one, you also dont want to be running more than a 80% duty cycle, especially if you are running stock peak & hold injectors. Anyhow if your car is tuned and has the proper A/F ratios now, if you install the new higher flowing injectors with the same duty cycle they will flow more fuel for that same duty cycle, so you will have to shorten it if you want to keep the proper A/F ratio. So if you fuel system is pushed to the max you might be able to make some more power, and you might have slightly higher fuel atomization if your injectors are old

 

you aren't running out of fuel...you don't need to upgrade your injectors.

187 whp is not 240 flywheel

 

heh, good point
