The Scirocco R is a very nice car. It has a class leading interior, fantastic exterior design, good grunt, and the TFSI 2.0L turbo motor has plenty of potential. Its equipped with the same K04 turbo found in the Golf R - and my old MKV GTI Pirelli. A simple $1500 Stage 1 tune lifts power and torque from 188kW & 330Nm to about 230kW and 410Nm Add an upgraded high pressure fuel pump, full exhaust, intake and intercooler and your looking at over 260kW and 460Nm. Even with upgraded front suspension, anti-lift kit and sticky tyres you can still expect wheel spin in 3rd gear at 80-100kmh. Won't match an RS265 through a corner but more than capable in every other area.

I've probably spent a couple of hours in one stint sitting in them and didn't notice any discomfort. But I can see how they could become uncomfortable on a long interstate trip.

I actually don't mind the base Cup seats. They aren't anywhere near as impressive as the Recaros but they hold you in place when you're punting the car hard better than you'd think. I am going to get my hands on a RS275 Trophy R in the next year or so. Totally impractical but ridiculous amounts of fun! http://www.caradvice.com.au/395185/2015-renault-megane-rs275-trophy-r-review/ OZ spec version gets A/C, Bluetooth, audio etc standard.

Renault and the RS265 encourage the driver to explore its capabilities. It even has track tips loaded in the RS Monitor info! Based on my results I've no doubt a stock 265 is capable of 0-100 in 5.6s Exhaust, intercooler, intake, tune and extra boost results in roughly 250kW and 450Nm. They don't need anymore than that. Not many sub $45k cars can stick with one on a winding back road. The hardcore (no back seats, OEM super sticky rubber) RS275 Trophy R is quicker around the Nurburgring than the Merc AMG A45.

I can't wait to see what the next RS Megane will deliver. The current RS265 and RS275 are absolutely brilliant! They may lack in a few areas in comparison to the Golf but they certainly make up for it in terms of the driving experience. Renault state the RS265 produces 195kW (201kW for the 275 models) and 360Nm but from those in the know it's actually more than that. Renault also state 0-100kmh in 6.0 (5.8 for the 275) but after a few minutes to acquaint myself I had my first attempt and despite a less than perfect launch recorded the data as per the attached RS Monitor screen shot. Obviously the 0-400m time is significantly slower than what it's capable of.

Cheers Prank [emoji106] I miss The Bee. I modified it to APR Stage 2+ level with 260kW and 460Nm - produced just shy of 215kW at the front wheels. Had the DSG software upgraded too, so if was even quicker through the gears. I never got a chance to run it over a quarter but it was certainly capable of a 12sec pass and over 110mph. I have tweaked my RS Sport Cup mildly (dump, intake, tune, boost) so it produces a bit over 200kW and about 380-400. Stock they make 165kW and 300Nm. But it's forte is through corners.

The Golf GTI and R lead their class in interior quality, design and features and have done so since the MK5. The TFSI engine is a brilliant bit of kit. My MK5 GTI Pirelli went from 169kW and 300Nm standard to ~260kW and 460Nm (212kW at the front wheels) with a few simple upgrades. Exhaust, intake, fuel pump upgrade and retune. The MK7 GTI is rated at 162kW (169kW with the optional performance pack) and 350Nm. The MK7 R produces 206kW and 380NM. A Stage 1 retune increases these outputs to 235kW and 516Nm for the GTI and 283kW and 523Nm for the R. Nothing more than a retune with extra boost.

My collection of European automobiles "Yellow" isn't mine, just had it on loan for a while. The RS265 (& RS275) is the best hot hatch I have ever driven. The hype is justified! Drive one and see for yourself. Sadly I sold "The Bee" (named by my eldest son due to the yellow and black/carbon colour theme) to make way for more practical transport and to free up some cash for other projects.

Right, got it. A 1:1 regulator is there to maintain the base pressure. Despite my misunderstand, at the end of the day, running the data through a range of online injector calculators (58psi base press, 6 x 1000cc, E85 etc.) where my misunderstand has no bearing, each case results in the same outcome. ID1000 injectors will support 750hp - possibly more given I worked off 90% duty cycle vs the 97% reported in this particular application.

Looks like back to basics for me then. I assumed (incorrectly it would seem) that base pressure is set on the regulator. In this case 58psi. Then assuming a 1:1 rising rate regulator each pound of boost will equal 1 pound of additional fuel pressure. At 25psi boost the fuel pressure at the rail, and therefore the injector, is 83psi. Running the numbers through a range of online injector calculators, 6 x 1000cc at a base pressure of 58psi is more than enough to support 750hp with duty cycle to spare (90%). Real world examples support this. There are always exceptions but I suggest there are other restrictions in those cases.

Of course it is 750hp at the engine. I thought that was obvious. As for the rest of the debate, I'm not weighing in. I am merely pointing out the capability of a set of 6 ID1000 injectors.

Based on Injector Dynamics own data, the nominal flow rate of their ID1000 is 1015cc at a base pressure of 43.5psi. The car in question, based on the data provided by the owner and tuner is running 58psi base pressure. This is just shy of a nominal flow rate of 1180cc. Add 25psi boost, and as previously stated, we are looking at 83psi peak fuel pressure. According to Injector Dynamics that is a touch under a nominal flow rate of 1390cc. At 83psi the injectors are safely within the ID1000 maximum fuel pressure rating. I assume the fuel system consists of appropriately rated dual feed lines and return fuel line, to go with the twin Walbro 400hp E85 pumps and preferably a twin-entry rail. All assisting the set-up to reach the nominal rating. Using this data and running it through some very rough E85 specific injector calculations (1390cc x 6 = 8340cc / 11 = 758hp) we can see that ID1000 injectors are capable of supporting approximately 750hp in this specific example.

So let me get this straight, you want people on this forum to make an effort and provide you 'some information about this ASAP' (it's made of metal... it's reasonably heavy... it doesn't have wifi) but you're not going to bother replying, not even a simple 'thanks'? Sounds like a great attitude. Good luck!

I had a mate with a Mitsubishi Scorpion! I'm not 100% but I vaguely recall it had the smaller 2.0 motor. Haha! Brings back some damn funny memories.

I had the exact same reaction when a mate pointed it out! It is indeed equipped with an Astron 2.6, complete with an aftermarket turbo set-up producing 140kW at the wheels on 7psi. I had one of the last Sigmas to roll of the production line before Mitsubishi switched to the Magna. Mine was a 1986 model with the Astron 2.6, big block of four cylinders.

Ben, don't cut corners with tyre choice mate. At the end of the day, tyres (and suspension) are the key to putting power to the ground, especially so in RWD configuration. You want as much grip as you can get. You can buy Toyo R888 in 225/40/18 for $300ea. Nitto NT01 are even less at $225. Add maybe $20 for freight costs to Adelaide. Pretty good value for a 80-100 tread ware rated semi-slick tyre. Neither will match a Yokohama A050R or Hankook Z221 but at half the price they are excellent bang for buck and will provide more grip than KU36, RS3, 595RS-R or RS-RR. http://www.stgeorgetyres.com.au/productstyres.aspx?widthid=57&profileid=70&diameterid=85&PageURL=tyres http://www.nittotire.com/race-tires/nt01-dot-compliant-competition-road-course-tire/ The next step is a dedicated traction control system. I decided to go with a Racelogic system. They recently discontinued the Racelogic TC system but will continue to provide full support to existing users.

Double post. Sorry!

Cheers Prank, cheers guys [emoji106] All Japan Day in Adelaide on Sunday, noticed a clean and tidy semi-sleeper Sigma wagon, with genuine Ferrari 612 Scaglietti 4 piston fronts still sporting the Ferrari logo!

Not quite as visually spectacular nor the stopping power of many of the examples thus far, but they are mine. 356mm 8 piston and 356mm 4 piston 18x9 and 18x10

Have no personal experience with Hankook's Z221 but from all reports they are the equal of or better than the A050. Well worth a look if the price is right.

Federal's 595 RSR is the control tyre in the Circuit Excel series (have 2 in the build at the moment). As admS15 stated, bang for buck they are pretty much unbeatable. The A050R is the best of of all the options mentioned, it's pretty much the pinnacle for setting lap times. That's why it's used in so many forms of motorsport - WTAC, IPRA, Targa Tas etc. Unfortunately they are very expensive. There are plenty of other more cost effective options if you don't mind dropping a few tenths of a second. I had a set of Hankook RS3 on my old Caldina GT-Four N. They replaced a set of KU36 (TW of 180). Upon release Hankook rated the RS3 140 tread wear. The set I had were 140. Since then they've regraded them 200. I believe the compound remains the same despite the tread wear rating change. They certainly provided more grip than the KU36 and wore quicker. Oh, Ben, one more thing, the A050R was designed to provide grip right from the get go and maintain that grip level throughout the life of the tyre. All the IP guys I've talk to gained upwards of 1-2sec a lap switching from the superseded Yokohama A048. They also agree the A050 provides more consistent grip over the life of the tyre - lap records have fallen on old and worn A050s. In summary: A050R Daylight 595 RSR Z222 / RS3 KU36

Ben, I have used a reasonable range of motorsport orientated tyres over the years, including both the RT615 and R888. In fact, from early 2013 till Jan 2015 I had RT615 235/40/18 on the front and R888 265/35/18 on the rear. The Federal RT615K has a UTQG of 200 A A vs. the Toyo R888 100 AA A From all reports the new Toyo R888R has a tread wear of around 80-100. Whilst it's somewhat difficult to get an honest and accurate assessment when comparing UTQG ratings* between different tyre manufacturers I can confidently state the R888 will provide a lot more grip in direct comparison to the RT615. *Grades are assigned by the tyre manufacturer based on their test results or those conducted by an independent company hired by the manufacturer. I am currently running Yokohama Advan A050R on my 33, which provide significantly more grip than Toyo R888. We run the A050R on the Sprinter as they are the control tyre in Improved Production. I believe the Advan Neova AD08R uses a similar compound to their flagship A050R. The AD08R has a tread wear of 180 and is significantly cheaper. AD08R: 235/40/18 $319 RRP 265/40/18 $419 RRP A050R: 235/40/18 roughly $520 265/35/18 roughly $540 - I paid $480 and $500 via IP club discount.

There are other options that will meet 'most' of your requirements. But not many available with an off-the-shelf T3 internally gated exhaust housing. Precision Turbo (Shaun is familiar with PT stuff) PT6062 CEA GEN2 (rated up to 750HP) is available with a T3 5-bolt housing which could be set-up to run internal WG. A little bit of stuffing about though. Forced Performance have their new Xona Rotor range, which is basically their previous FP comp/turbine wheels with a new CHRA. But no off-the-shelf IWG option. If you switch to external gate your options increase significantly.

Adam, A Borg Warner EFR8374 matches most of your requirements. Rated up to 800HP (79lbs/min compressor) and capable of well over 400kW at the rear wheels on E85. Available in 0.83 A/R T3 internal WG. Garrett's GTX3582 is available in a T3 twin scroll but only external WG. However they do have a T3 0.82 internally gated turbine housing. It will produce less power than the EFR8374 but probably provide slightly better response. Here's a back to back comparison between the smaller Borg Warner EFR7670 with a T3 0.83 vs. a Garrett GTX3582 T3 0.82 on a 2008 model STi running pump fuel with 50/50 water methanol injection: Opt for the 400kW car... you know you want to

Hi mate, Yes I recall my car occupying that hoist for quite a while! It's spent plenty of time on the hoist at the current BW workshop. Your beast might be a tiny bit rough around the edges at the moment but that's to be expected in the middle of a major build project. I'm tipping the finished product (they're never really finished) will look awesome! No worries at all mate. keep up the good work.
