Supercharger for Occasional Track Use?

AntiVenom

Alright guys, I've spent the past couple of days looking for info. So far the only thread that was valuable was TravisJB's build, but he was driving at an an advanced level (at least he is/was beyond my current skill and track frequency).

What I want out of my build:
-400+rwhp
-streetability
-track readiness/"reliability" for (2-4 track days a year)

What I have already:
-GTM Stage 1.5 S/C Kit (it was a damned good deal that i could pass up). this will more than blow my WHP requirements. In fact I am thinking about trying to locate a larger pulley in order to run lower PSI. Even if I don't I will be getting it tuned for engine safety vs. max hp (i know there is no true safety tune, but hopefully you take my point).
-GTM baffled pan, 34row oil cooler, CSF 3pass Radiator

What I am worried about:
After reading travisjb's journal, I feel that in addition to the 34 oil cooler and the CSF rad. I will need to add some more cooling. Why?
-intercooler blocks the airflow significantly. this is probably the hardest to combat. i think the only solution for this is ducting to make sure all the air is forced through the radiator.
-with the GTM kit the oil cooler is moved in to the driver's side, behind the bumper, outside of the airflow. Initial thought here is a fan and vented fender liner. I would prefer not to add vents to the front of the bumper, but would consider it if necessary. also have considered a second oil cooler. thinking i would do a laminova water to oil cooler, in sequence with the 34row (water enters laminova unit first, then hits the 34row). i think this would work well if the coolant temps stay in check.
-vented hood. AMS style, since it seems to have the largest vents. Although there is a terminator style VIS hood that seems to have the vents more centered over the radiator. primarily interested in venting (looks is secondary since i would likely not keep the hood on unless i was going to the track).

My questions:
-am i overthinking this since it won't be a dedicated track car and i won't be trying to eek every second out of a lap?
-can i get away with a fan on the 34 row with the fented liner, and the vented hood?
-do you guys estimate that i would need the second cooler and some custom ducting?
-what do you think about the laminova>34row setup, given the radiator air flow problem caused by the intercooler? would this just add more stress to the system (seemed like travisjb was using with relative success even without the 2nd 34 row cooler)
-is placement or size more important for a vented hood?
-anything else you can think of?


sorry for the long post. i generally am able to find 99% of my answers in other threads, but this doesn't seem as well documented. maybe because it's a bad combo.

You will never receive your kit from GTM.. This is a much bigger problem then keeping it cool

I am aware of the GTM debacle. I got it new/unused from a forum member. Already sitting on my doorstep.

edit: for the sake of the thread let's pretend i didn't even mention GTM I suspect turbo cars with FMICs would face the same problem, maybe worse.

Just re-read your post. Missed that part originally. A 34R oil cooler, triple pass radiator, and vented hood should get you close to where you need to be. Check out djtodd's journal. He is boosted and tracks his car a lot.

Just read through it based on your recommend. He's got an awesome track car. Seeing what he is doing definitely makes me feel better about the cooling mods I already have in mind.

Thanks for the suggestion.

I have the BP single turbo and I track it a good amount. I have the CSF radiator, 34 row cooler and vented hood. If it is really hot outside I may have to end a session a few laps short but by and large there are no major issues.

AntiVenom

thanks for the response ENT-Z. where did you place your oil cooler? is it off to the side without airflow?

I would speak with DJtodd, he has a Fast Intentions TT kit and tracks regularly.
Here is his build thread on what he has done for cooling and other upgrades: DJTODD's Journal - 2012 370z Nismo

Additionally, JWillis72 has a Stillen SC & has been tracking and working on tweaks to keep the temps down.

Thanks Dreamer. I checked out DJTodd's Journal, but it was sparse on info. I will PM him directly to see if he can give me any tips/tricks. Sounds like he is probably going to be the best source of info since he has FMIC.

The Stillen kit allows for a bit more airflow as the heat exchanger doesn't block the radiator, as i understand it. Which also means that the oil cooler can stay in the airflow.

edit: I did find this thread useful JWillis thread useful though. Radiator Cooling suggestions (thanks for suggesting his name)

edit edit: i also see has the upgraded front mount heat exchanger for his Stillen kit so his upgrades are very relevant to my questions.

The standard stillen kit does, but most upgrade to a front mount cooler to help with rising temps so it does block some air flow. Though not nearly the same as a TT FMIC, but it seems from what I have read the main things are:
-Getting air into the proper places
-Getting hot air out effectively & quickly

I think many people focus on the coolers, larger front air intakes, etc. but forget that the hot air needs to get out of the engine bay which does not happen easily from factory. So vented hood, fender liners, etc can be larger factors.

after further reading seems to me that the next step will be vented hood and to get some more air in.

seems like stillen and fujimara fronts have the biggest openings. however, i might try vents in the front of the stock bumper as i was hoping to keep it looking stock-ish on the exterior.

No sir it is in front of radiator and behind FMIC
