how much is too much

DIGItonium

It is my only car at the moment. On snow days I borrow my parents car since my dad already has to take my mom to work. I will look for a daily driver next year, though. That way I can handle the downtime to do some minor work on the Z like finally replacing exterior stuff that suffered tough times as a daily driver.

When you're driving casual as a daily driver, it hardly gets into boost. You have to hold the throttle at least 50% and let it rev past 2.5k RPM for it to boost. Even with moderate throttle and letting it rev past 3k RPM it won't get into boost. It pretty much behaves like an n/a car.

Has anyone done any long term reviews (still searching) for a GTM SC kit. There is a guy selling a slightly used kit so thinking of installing it in my daily drive. My drive is mainly freeways 170 miles daily plus there is a heat factor here so will it run fine if tuned conservatively on 350-360ish whp ofcourse with proper cooling

I don't see why you can't DD a boosted Z. Remember, you don't see boost until you're actually on the gas pedal. Cruising around with light throttle is no different than driving around N/A. If the kit is well installed and all the lines are properly fitted and torqued you're good to go.

I'd use a 7 psi WG spring pressure for daily driving, and a boost controller to run up to 10 psi when you feel like it. I'm assuming a stage 1 kit.

SC might be different then a turbo setup in terms of boost setting. Your daily drive mileage is less compared to what I'm asking of 170-200 miles round trip daily coming upto 4000 miles a month.

Was looking for more long term testing if someone has done it, know one guy here with a similar kit on G35s sedan he do get heating issues in traffic and more during summer months

Even our stock G's will overheat in summer in traffic here with A/C on full blast lol

The S/C is always making positive boost and is always putting extra load on the engine. Wish they came with compressor clutches like A/C compressors so you can switch them off in summers

I have a feeling if you S/C your Sedan you will end up parking it at home and commuting in your RB powered Z to work!

If you are worried about the Dubai heat, I suggest that you get the largest engine cooler, trans cooler (if auto), radiator, and run a methanol setup with a 50/50 mix for extra cooling. I have about 24,000 miles on my daily driven SC'd G35 Sedan and see about 5 psi at 3500 rpms and 11 at 7300. I think the methanol/water mix has helped tremendously during hot Texas days.

Even though I'm not DD I already have the basic covered for my car already for my FI build soon. I have 34R, CSF radiator, no AC (which is not reasonable for DD), Stillen front fascia (allows more air flow), vented/ gutted hood, and with GTM's new oil pan it will help tons. I'm also going to make some custom ducting into the engine bay I've came up with. I also don't run a cowl so that another big thing.

Also with a FI the Uprev can be used to turn on the fans sooner.

are all these miles with SC or just the mileage? I have driven already 35k miles since i got it in 14 months . Coming to normal rpm range 5 psi will be the boost level most of my drive time which seems encouraging.

Bigger oil cooler already there with the kit and CSF/PRC radiator already on the list along with Spal fans and shroud. Methanol maybe for occasional use I can think off but dont want to depend on it that why asking here. Cooling in bumper and hood is not an issue.

Installed my stage 1 SC at 19,000 miles and sitting at just under 60,000 miles now.
My daily trip varies, not nearly 200 miles a day, but probably 50-100 depending on where I am going. My biggest things was cooling with the Texas heat. Upgraded radiator, good size oil cooler, soon I will be adding a vented hold & fender liner.

Other things are keeping up on maintenance, and monitoring everything. I run at 400whp and start seeing boost at 3,000 rpms but cruising in 6th at 70 or slower I can keep it at 0.0 all the time. MPG I am about what I see factory minus those days I get on it, but just driving it is not better or worse.

My Z is my only car and is my DD. That said I have my girl's Tahoe as well. I drive my car like I stole it most of the time. Maintenance is the key. As long as you are very familiar with your machine, you can diagnose possible issues before they arise. As far as boost goes, I am running 0.5 BAR (about 7.2-7.5 PSI) on low setting and 0.9 BAR (13ish PSI) on high setting. With that said, it all depends on your right foot. I don't break out with 6k RPM launches and WOT blasts regularly. Driving habits and maintenance are the keys to a DD TT Z. Have fun..........and don't forget about the "Oh ****" fund.

Oops,
I meant to say I see about 5 lbs at about 4500rmps, not 3500. The methanol/h20 kicks in at about 5lbs and is only used for safety and cooling. Occasionally I'll turn the meth kit off and switch to the appropriate map when I know I won't need the meth. The surge of the SC is very enjoyable, and it's very easy to keep out of boost when desired. I have 53k total miles on the G and 24k of them are boosted. Started out with the Stage 1 then graduated to the 1.5 after about 10k miles.

Thats very encouraging

Are you on stock radiator if not which one? I was looking for an aftermarket radiator last year for my friend's G35 couldn't find anything (working on the Z made me forgot everything on these cars lol)

PRC people make great custom ones.
