    Local Supercharger Expert - ISF

    GO for it if they can tune it what's holding you up ( and don't say your legs) :w00t:

    There's a bloke putting a RR supercharger on the UK forum and no change out of 10000 pounds :wacko:

    There is always someone out there with the deep pockets willing to push the boundaries, that fella from the UK is about 25k pounds into the mods now. Bloody norah. 

    The tune is something which concerns me, whether or not it would have to be an aftermarket module, which doesn't interest me in the slightest..

    Guys we have to leave emotion at the door and consider all the additional costs/potential pitfalls:

    Completely agree!

    * tuning. There will most probably have to be an AM computer involved. Remember how hard it was to crack our ECU and that RRRacing were one of the only ones to do it - this component alone is approx $2500

    If RR Racing can crack the chip for a supercharger, there are others in the forum with a tune already, an Australian tune (including me)

    * I’m hearing $16k from one person and $20k from another - with initial builds the budget and timeline will blow out!! Also chance for the builder to get half way through and say “it’s the first one, I thought we could, but it can’t be done” .... but I still need to be paid for all my R&D and time spent on the tools

    Absolutely agree, always risk to not complete and costs could get scary.. But i believe this guy would deliver. Look at their other work.

    *does this account for oil coolers, transmission coolers etc? These all add up

    Not needed unless tracking the car, and if you track the car you should get these anyway.

    *our engines couldn’t handle much more boost as we run such high compresssion

    Yes, they feel 6psi would be max (same as RR Racing, and same as the 6.4 Hemi superchargers they do.

    * I’d rather give my car to someone that’s already put in the time for R&D themselves, not where I’ll be paying for it. Remember labor is around $120-$160 per hour... you do the math. There will be a lot of fab work needed.

    If there was a saving (even perceived) with using RR Racing, i would go for it. Problem is, after shipping and currency conversion, there probably isnt. And compare the installs, one looks like it belongs in a street car mag (fine for many, maybe Im old?!) and one could have come from factory.

    dont want to burst anyone’s bubble, just trying to be realistic. Feel free to challenge me on any of the above , I’ll be happily proven wrong 😊

    I actually feel you on every point, it isnt simple, and realistically the car already is quick with full bolt ons (almost), so all the extra power is probably a waste of money and unnecessary. But that's probably what RR Racing were told a couple hundred times, someone just has to jump in!! (bags not me) haha!

    Carbon build up / Italian tune.

    in Lexus IS-F Club

    I had the same thought, so i did a "water / steam clean", after some instructions from the US forums. A few engine builders (including RR Racing) said it was as good / better as any special treatments you can buy, the super heated steam basically blows all of the carbon out from the engine through the exhaust. They do it before performing engine rebuilds as it's a lot less messy.

    Here is basically why you do:

    • Get the car hot, proper hot. Like a big drive when heat soak sets in, come home then keep the engine running.
    • Get a 1 or 2 litre bottle with a small hose (very small) and connect it to the spot shown in the photo below.
    • Whilst keeping the car running, let the water flow into the engine and keep the revs up, to around 1200-1400 rpm. It will suck through the hose just plonk it in the bottle. I used some thin irrigation piping (clear) from Bunnings. 
    • Repeat if needed with 2 or 3 bottles if you want.
    • The car may throw a few warnings on the screen, keep the engine running for a few minutes after the water is through, and give it time to get through fully before turning off. Dont worry about the warnings (VSC etc).
    • Turn the car off completely, then restart.
    • Codes will be gone.
    • Take it out and thrash the skin off it
    • Voila!!

    You can actually disconnect the battery as well before you take it for a drive, pump the brakes a few times with the terminals off, this will discharge power completely to ECU and "reset" the knock sensors and give the engine to reset the timing to allow more aggressive tunings, minus the carbon buildup.

    Thats it. Very easy.

    Interesting BUT no intercooler and who will tune it ?? you know you want it though:yes:

    It has a water to air intercooler like the ones HSV / Holden etc use, inside the unit. Hence the cost is a bit higher than the entry units. Its got all the bells and whistles, without attracting attention from the fuzz :wheelchair:

    They tune them all themselves, and do a good job!

    I have been looking more and more into the options of developing more power for my ISF, and have dreamed of supercharging a car since i was a little fella.. The noise, the torque, the instant torque i should say, the whole package is the dream. I dont like the "bling" of the RR Racing package for the ISF, it's too obvious, too intrusive, and a lot of fuss for something running such low boost. In my opinion anyway.

    So, i don't know whether or not any here are familiar with a company called "Bullet" who specialise in superchargers, and who actually have a further specialty in Toyota / Lexus products. This is them:

    http://bulletcars.com/

    So they were best known a while back for shoe-horning the Toyota V8 into the MX-5 body, and then supercharging it. These little track weapons were rocket ships, I always had a soft spot for them!

    Bu i digress, i got in contact, and though they warned it would be the first one they have done, with the expected delays and costs in producing something like this which would essentially be treated as a "one off", its definitely possible. Here are the best parts of their reply:

    • Harrop HTV 1900 supercharger - low profile, looks factory, great product used all around the world.
    • Huge increase in low RPM torque and power
    • Same reliability
    • THE ENGINE COVER STAYS ON!!! OVER THE CHARGER!!!

    So its the real deal, looks factory etc etc, huge power increase, uses the factory intake system. Sounds amazing right? Well all except for the cost, $16,000 or more as an estimate.. Because it will be the first, it will be expensive. So, who else wants to get a kit, come together and potentiall reduce costs? I am interstate fo the company also, and couldnt be the guinea pig, but anyone want to be?

    Its a lot of money to spend on a car worth what they are these days, but once done, what a weapon..

    I have attached a photo of a Lexus 430 which they did, cover back on, no one is the wiser. Except those behind you.

    I have only been able to test on rubbish (proper rubbish) roads in the country, I had to leave traction on as it would just completely light the tyres up if i didnt (even with LSD). By nursing it, and keeping traction on, i could only manage 4.9s, using Harry's Lap Timer GP. / Kiwi 3 dongle.

    I have:

    • Widened primaries
    • Widened cats
    • X-Force exhaust
    • Tune
    • Intake pipe and filter.

    I gained about 40kw at the wheels with the mods, so yes with some new tyres (these are post track days and skid pan days), good roads, i would expect low 4's.

    GSF HEADERS

    Beautiful car, great news about the headers! For the cost of removing and reinstalling, could almost buy a new pair.. Actually with the extra room under the bonnet of the GSF may not be a hard install?

    Very jealous, definitely the number one car i would like to have my ass in currently.

    What's your fuel economy?

    anywhere between 10-12 on average with normal/ spirited driving

    around 15 on track 

    on long trips its dropped into the high 7s

    Tuned by James at BPS

    15 on the track..?! Come on man thats got to be a joke, i refuelled halfway through the day on the last track day, and then almost emptied it again. I know he may be running lean numbers, but that is BS.

     

    16l for me average. I work 5 min from work, and drive short trips alllllllll day working in property.. Car barely warms up on the way to work in winter.

    8-8.4l on the open roads
