Buy 7 more and put one in each runner. LOL. I dont know alot about the dry kits but I think you have to put it infront of the MAF. Other than that I dont think it'll matter much since you probably wont spray to much.

If you are depending entirely on the MAF to add fuel, then yes, the nozzle needs to be pre-MAF. Nozzle placement is critical in this situation. But, the OP has a Harris Interface which allows more flexibility. Some even install the nozzle post-MAF. We need more info, what nozzle do you have? Is it straight or 90 degree or some other angle? A pic of your intake setup might be helpful too. I'd still be tempted to install it pre-MAF (6" to 9" in front of the MAF) and use the Interface to tweak it.

it's a 90 nozzle,just was wondering if right in front of the tb is better or worse than a little farther back for better fogging of nitrous. intake is the hardcore homemade 1.

Ok, had to do a little searching to find pics of the Hardcore Intake. Hopefully this looks like your setup.





If you want to mount the nozzle post-MAF, that straight metal tube right in front of the power steering reservoir piece looks like a likely candidate. This will require more fiddling and tweaking to get the A/F right. You better have a wideband. I personally would install it pre-MAF in that metal connector fitting between the filter and the MAF. That will let the MAF do most of the work and then you can do minor adjustments with the Interface.

Unless you have the wideband and tuning software keep the nozzle in front of the MAF. I'd still run the wideband, it's great prevention

That is actually one I installed myself (for Plumcrazy1).. I have mine in the straight metal tube right in front of the power steering reservoir.. But mine adds fuel though the tune not with maf...
I would check with Harris Speed they know best

Dry kits get installed before the MAF so the computer can make fuel changes.

For the most part Yes... but the MAF doesn't always register the spray, and sometimes the MAF even Fails because of the spray..

I some advanced Dry Kits Setups you spray after the MAF and the Tune adds the extra Fuel.


Like mine

DO NOT put the nozzle before the MAF and run the HSW Interface. The whole point of running the Interface is to trick the MAF into adding fuel without actually spraying the MAF with nitrous. If you install the nozzle pre-MAF and tweak it with the Interface the only thing you will have accomplished is adding another point of failure, i.e. the nozzle placement/MAF reading or the Interface could fail. I installed mine after the MAF in the 90 degree bend of the stock intake tube spraying directly at the throttle body. Call HSW if you have any questions.
