Agreed It seems to me that your Cooling of the intake air is the major sticking point here. I would get the 3 inch done and then, i would throw some WI in the mix a simple kit with a 2 gph nozzle set to come on at 9 psi or so should allow you to run 14-15 psi with the effeciency that you would like to have. But remember when you throw in the WI you need to tweak your fuel and timming a hair to make sure you take advantage of the cooling effects. Just to be safe i would spring for an aditional 3gph jet as well. Given the effeciancy of your IC right now the 2 gph should be ok for the extra 100-120 hp you plan to push out. This is also abit dependant on your mix of methanol as well. I like 30% best but your results may vary. GL

Thanks for the help guys. My biggest problem now is that I have no cat and I have to get my car inspected within the month.... Think I'm going to do my exhaust now so I can pass. You don't have to have a muffler to pass right?

As far as i know no. :bigtu:

Clear up some confusion for me.
He's upping the boost from 12 psi to 14 psi and starting to see pinging and overheating on the exhaust charge. How can you guys tell the difference between an intake charge cooling problem and a fuel supply problem? What are the AFs and EGTs? Is fueling maxed out with his current fuel management? |
Well, without looking at duty cycle of the injectors and AFRs at the wideband O2 sensor, you couldn't tell the difference between pinging from hot air or pinging from lean condition. This guy's got a Link ECU, though, so he can track AFR and duty cycle, so I'm assuming he's already ruled that out [lack of fuel].
If not, though, then you're right: he should definitely look into that. |
2.5 should support more than 300 hp. I would look at the turbo like mark
