Can a dose of nitrous be used to cool the air in the intake piping for 1/8 - 1/4 mile drag race runs in lieu of an intercooler?
I'm taking about a seldom used application.
I have a 4.6 2004 Mercury Marauder, with stock internals, equipped with a Vortec supercharger making 431 RWHP, 10lbs @6K. (recent dyno tune)
I bought the S/C kit when I had a 100 shot Zex wet system but the cost of the SC kit with Intercooler and piping was more than I could afford. However, the installer told me that if I dropped the nitrous pills from 100 to about 25 I could use the cold gas to cool the inlet charge, assuming that both the fuel and gas sides worked. Sounded reasonable.
A problem developed early on in that the ZEX programmer (purple box) failed. The replacement failed also after one run so I couldn't tell if the theory works. I didn't have a means to measure IAT then, but now I have (Scan gage).
I do have the ZEX traction control box so I can program the Zex system to turn on and off at different RPM's @ WOT.
The Zex programmer, purple box, that's in the car now works only on the Nitrous gas side, so my thinking is to drop the pills to a 15 shot, program the traction controller to turn on at 1K RPM and turn off at 6K, thus cooling the intake air charge.
Is my thinking correct?
No I still can't afford an Intercooler and associated piping plus installation and no more investment in purple boxes. But I want to use what I have. Power is not my problem, a cooler IAT is, because the PCM will pull timing when the IAT gets hot.
Thanks for your consideration,
Pat
