Ok, I started the same sort of thread on the SDU web site but, lets face it this forum is MUCH better. OBJECTIVE : Do mid 13's(possibly lower) all day with the standard ecu, intercooler and turbo re

Shielding the pod is a great idea - the majority of air will be coming from the front of the car, the ambient heat from behind the filter basically acts as a contaminant to your nice cool air. The front of your car has a huge high pressure zone when you are moving, so long as you allow a path from there to the filter your car should not be starved in the slightest.

If the air is flowing from the front how is hot air from behind going to 'contaminate' the air flow into the POD?

I'm not saying you are wrong just wondering.

It could be that dyno results which 'prove' a shield is necessary, only do so 'cos the car is not moving (on the dyno) and so no 'cool' air is flowing from the front - w/out a shild the POD is just sucking in air from 360 deg around it which includes hot air around the engine. On the road it won't be like that of course with the 'cool' airflow from the front?

so lithium how much rwkw u make at 6.7 psi???

The hell kind of question is that? I am pretty sure it made around 180rwkw on 7psi during a very early tune session, ran low 14s like that. I can't run any less than 12psi with the current setup - drag season is coming up, could have a friendly manual versus auto comparison :yes:

line up a v8 with a c4 transmission and same rw power and see what happens

I think you'll find that a typical V8 drag car automatic isn't setup quite the same as what the auto in your GTS25t is, hardly apples for apples. You Best tell the funny car and top fueller guys to get rid of their clutch setups and go torque convertor! Of course you CAN get your Jatco rebuilt to handle some decent power and stall/shift more aggressively so it actually does suit drag racing....

so ur setup only made 20 rwkw on my standard setup lol

I'm not sure what you are getting at or trying to achieve here, if you have something you need help with specify it please. It'll be good to see how you go with the auto - never said it won't go fast, it just could be a challenge unless you have or are going to get it modified to suit what you are doing.

Just for clarifications sake - you made 150rwkw on 7psi with stock turbo and I made 180rwkw on 7psi with stock turbo, and you somehow come with a comment lolling I only made 20rwkw more than your stock turbo? Given I made 30kw @ wheels more than you on the same boost with the same turbo, I am actually struggling to work out what you are going on about.

Ahh right sorry, when I said "I can't run under 12psi with the current setup" I meant with the GT3076R vs the stock turbo - I couldn't run 7psi if I wanted to with the bigger turbo.

how bout 13.061 on stock turbo...stock ecu....only exhuast/fmic/boost......on street tyres as well....2.00 60ft...

Not un-realistic if you get a good run and launch.

It may be a high goal, but im aiming to get as close as possible to a 12.999999 with stock ECU and bolt ons and street tires.

When im convinced i cant do any better only then will i try on some semi slicks.

If you can nearly do it, then so can i :D

yeah....super close to my goal....cant help but be a little disappointed it didnt crack the 12.....but theres no way i could launch any better absolutely no tyre slippage, it just stuck....tyres couldnt hold any of 2nd....chirped 3rds....and the rest is pretty straight forward....

best time on my other r33 was a 13.08 on some pretty used drag slicks....launch was a bit better...1.911 60ft with wheel spin....slipped part of 2nd....chirped third.....trap speed was 4km/h off ^^

but a 12 is possible....bloody difficult....the rest of the runs on that night were around 13.3-13.5....poor launching by comparison...

Interesting..

Only thing i will suffer from is horribly poorly prepped drag strips :D

Not quite the money around down here in NZ involved in the strips. But hey, just a handicap eh? :D

      Yep, that was one of the things we learned fast in the past with our MX5. When you drive with the top down, you are effectively standing out in the sun, 100% of the time, and not getting in any shade (because roads aren't shaded generally!). Just like standing out in the middle of a field on a sunny 27C day is a bit of a bad plan, so is sitting in a MX5 without sun protection.

      I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it

      If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣

      I would agree, unless you need something specific to the HV motor/battery side repaired or investigated, any mechanic will be able to perform normal services, but if you prefer, maybe look for a mechanic who regularly services/repairs Nissans, the VQ engines are pretty common in the Nissan lineup.  Sorry, I can't make any suggestions, I don't live in Vic.

      Some of them keep working fine. 9 out of 10 of them end up causing an absolute misery bleeding the system and get thrown on the workshop floor in a tantrum and never thought about again because they were never really needed and just added crap to the car that we could have done without. Same-same with HICAS, A-LSD, and various other stupidities that over eager 10x engineers thought we had to have.
