I'm experiencing this issue as well. I opened a few discreet holes with a hole saw in my bumper and I'm running at about 227-228 degrees on my coolant temps after pulls. I've been running around 220 degrees when cruising. Last night I opened up two more not-so-discreet holes with ducts to either side of the Nissan logo. I'm not a huge fan of the look. I haven't tested yet, but I'm hoping this will bring the temps down some at least. If not, I'm going with a Stillen bumper and vented hood.

So for someone that will never run anything but 93/94. Will never cut holes in their bumper or get an aftermarket bumper with holes in it.
Does this kit perform any better than the previous one?

I would not recommend this kit if you're not going to go with an aftermarket bumper or cutting up holes in your bumper. The older Vortech based kit did not seem to have this problem. I've also done a lot of TT kits and they don't have any cooling issues.

I'm personally not seeing any of these overheating issues. Then again, I'm currently just outputting 480 whp, and I don't think I've had the car out when it was warmer than 27C/81F outside, so that may play a role as well.

Definitely happy with the kit as a whole thus far but not so much my current tune due to the major start difficulties I'm having. I have reached out to Aaron now for advice on this and maybe end up with a remote tune from Eugene or something along those lines.

It's hot in Texas right now. 100 degrees everyday around Dallas where I live. I don't drive the Z everyday but when I do it is with AC on blast. Normal driving I see around 91C. If I make a pull it might go up to 101-104C but very shortly after it is back down around 90-91C. Having the AC on makes the radiator fan run constantly. I figured out that in the fall/winter when I'm driving with no AC the car actually runs hotter than in the summer. I think the programming is set for the fans to come on at 100C (212F) if AC is off.

My first supercharger kit so I don't have really any complaints or much to compare it to. It is not noisy like I have read the Vortech can be other than the BOV.

I talked with Eugene about this before installing. The benefits of this kit are that it's more efficient and has the ability to run higher boost if you want or are able to. When run at the same boost level as the Vortech kit, it's more efficient and produces more boost lower in the rev range. So even if a max hp number looks similar there is more power throughout.

I think the coolant temp issue is due to how large the intercooler is. A majority of the stock bumper opening is covered by it and by the lines to run the rotorex cooler and the core itself. I know this isn't a popular opinion, but my view for my car was that if I was going to run boost I had to be prepared to make other changes to accommodate a design that wasn't meant to be from the factory. It'd be nice if I didn't have cooling issues, but at the same time I was prepared to make changes if needed.

When it comes to heat, it is not just about more air into the engine bay or better cooling components (radiator/oil cooler/FMIC), you also need to get the air out of the engine bay.
You will see many with vented hood or fender liner to help airflow and pull air out of the engine bay.

Tube n fin vs bar and plate, open up the front end, better radiator shroud

Quick update on the cooling issues… I opened two more holes in my bumper next to the Nissan emblem and went for a drive. At 5000ft up a 10 mile hill at highway speeds my coolant temp topped out at 109c. It was just below 100 degrees outside so I’m sure that didn’t help. Once I got to the top of the hill and started cruising down the other side temps dropped back down to around 94c. I know that’s a pretty extreme example with the thin air and all but it also convinced me to purchase a vented hood.

I have a vented hood (Seibon TS style) and am having pretty significant overheating issues on hot days, even when I drive the car relatively calmly... well, maybe 1 or two short romps, but not really beating on it at all. It gets so hot you can hear the coolant boiling & it dumps out of the overflow tube. Going to try re-routing the BOV exhaust so that it's not dumping in front of the radiator. That can't be a good thing w/ all of that hot air being drawn through the radiator. I am running the stock (non-nismo) 2014 bumper.

Anyone have any good pics of this kit on a G Coupe without hood pins?

TopgunZ

There should be several as I have sold several and have sent the updated intake which allows the clearance. I literally only sold the 1 kit that required that hood pin modification.
