They are cheap as chips and for that money if they line up and work correctly you cant go wrong. In fact at that money you can think about going to a pretty good quality rotor and still getting out of the upgrade for less then $1000

But when you factor in the power people are making , you are asking the lil 20G wheel to flow around 590cfm or 42lbs ...if you look at the compressor map thats right at the end of its efficiency. Sure the E85 will help it along....but a turbo can only flow so much air. So the whole more power at less boost? If you are already making 280rwkws, by more power do you mean 5-10rwkws at 2 or sp psi less???

That is still the funniest in car video ever to come from a track day EVER

If I can sell some of my fluff laying around I could quite possible give the T67-25G a nudge. The crime will be is if I run it with E85 and the 10cm housing I will instantly losing $300-500 as it is brand new. Think I will have enough trouble selling them with the Kando things running around but not fussed. Some of the gear I dont really want to sell, just need to move enough to clear up some funds for further work on the R32 and Cossie rebuild

The PIARC Supp Regs state : NOTE: Both days are 95 dB(A) noise limited - Full Race noise allowed days. Don’t miss out They want me to go down there and make NOISE! err I mean music!

I don't get this "pumps hotter air" that I am reading in threads lately. Where is it coming from? You spin the same turbo harder for more boost and you will often get higher inlet temps courtesy of compressing the air. The intercooler's job is to remove that heat, which whilst isnt 100% efficient ...will remove the bulk of the higher temps if sized correctly. By the time you add fuel, compress and ignite it I cant see the inlet temps having a dramatic impact on the exhaust temps...it will affect the hp but surely it is negligible with regards to EGT Then you have the hot side and EGT. They can be higher due to the A/F you are running, the cam and ignition timing etc. Oor higher due to exhaust back pressure in the turbine housing or exhaust system as a whole. So unless you all go and plumb EGT sensors into your dump pipe with a pressure sensor in the scroll of the turbo then I dont think anyone can comment on whether somehting is fine or not as we dont know the numbers. I know on my old 20G setup with a 10cm housing that the pressure readings I was getting suggested that the housing was too big. My 8cm housing doesnt have a tapping for a pressure gauge so have never measured it...though my TD05-18G 8cm housing does so will be measuring it when I am playing with that setup

I have not bothered as the 20G with a 10cm housing was too big for an RB20. So I am betting a 25G would be rather ordinary on a 20. Would probably make a good number, but would make less than 200rwkws at 5,200rpm If i had a freshly built RB20 that I knew was well balanced and had a good oiling system it would be probably a decent enough thing to spin up between 5,500-9,000rpm.

Some more info on the RB25DE: RB25 NA head from an R32 1.5mm oil restrictor in head Standard RB25 crank Upgraded Valves and springs - New Water Pump - Following bits have less than 5,000kms Gates Timing belt Oil pump Forged Rods Forged Pistons and rings ARP Headstuds Metal Headgasket I bought the engine because I needed a complete head, and have not even taken the sump off the engine to see if the internals were as per the claim. The engine does have a head gasket, does have ARP head studs etc from inspecting it, If someone wants the engine, one of the Trust turbos and HKS manifold then will do a price in order to move it all...even better if you want the RB25 box and Exedy twin plate clutch with it

I am a maybe. I am doing the PIARC weekend before and will be out of tyres so makes the following weekend an expensive track day Also, this is a problem..."A vehicle noise limit of 75dB(A) to 30 metres drive-by will apply. No vehicle which exceeds this limit will be allowed to continue to participate." I have most of the bits for the new exhaust but wont be ready until July when I am unemployed with time to do stuff. If we are doing driver training I would like to come down and ride shotgun with people

My RB20 runs a 20G. The rear footwell of the car runs a TD06-73HTA.. The boot is running a TD05H-18G. The 3rd shelf of my bookshelf runs the T67-25G whilst the bottom shelf runs a TD06H-25G . Will try 25psi with the 20G tomorrow and see how it all goes

Nice to see the guys in their real skin http://www.youtube.com/watch?v=sN7ODEvh-cQ&feature=player_embedded

We knew it was going to happen, just wanted to try the corn juice to see if the engine liked it and whether it helped its tendency to ping. I think if nothing else this test has told me there is nothing magic about E85 and if you are out of compressor flow then you are out of compressor flow and E85 will only give you a few more killerwasps

Just curious, mine are 2.5" and the numbers suggest that for 590cfm it should be fine with 2.5", but as always its interesting that the RB26 and GTR run 3" std

Are you going to stick with 2.5" out of the IC into the plenum or go 3"?

What model steering wheels? Can you post pic or at least a picture of the models that are for sale?

Webber may not win the WDC, but is great to see him delivering the sort of race weekends we know he is capable of....especially when Vettel struggled this weekend it was great for RBR to have Webber bring home max points! He is looking confident and he needs to have a weekend in Canada like he did in 2010

Well me car is being E85'd at the moment and if the next two tweaks go to plan then I may throw my Poncams in as nobody has shown any interest in buying them. LOL, history will probably repeat

Yep! The thing was maxxing out its GTR injectors with a belly full of corn syrup so not a lot of time was spent trying to get a result, just a few dyno pulls to see how it behaved. So its hardly an exhaustive test and tune with E85, its just a little disappointing that other cars fill up with E85, load more fuel and ignition and they readily show signs of making more power vs my car that seems a little more stubborn. Fark Garret fluff..i have a an army of Mitsubushi turbos that will go on before I soften up and go roller girl bearing Just need to sell a few more parts so that I can play with the R32 whilst rebuilding the Sierra

How is it a Bradbury to qualify on the front row. Drive to the conditions and bring it home P1??? Heikki's win all those years ago when Massa lunched an engine with a lap or two to go in Spain is a Bradbury.

STOKED http://www.nieuwsblad.be/article/detail.aspx?articleid=PO3QF1PK Seems as though French GP negotiations are not progressing to plan under their new Socialist govt. Hopefully this means Spa aren't being strong armed with " I will take the GP elsewhere" talk. Come on Bernie...do the right thing!

Its only one wheel but failry typical of the wheels. No/minor gutter rash and general good condition. However clear coat can do with a once over. Also have a complete R32 RB25DE that is freshly rebuilt that I want $1700 for along with an R33 RB25 gearbox that I want $1400 for. The R33 gearbox came out of a std car with std clutch that was bought and torn apart so the shell could be used for a drag car

Lets see what Webz can do the next few races. If he can win all the remaining races then he will be WDC

Real interested to know if the original tune was by the same tuner ? If the before tune was by the same guy then that removes a variable of it being overly conservative

Watching a post race stream there is talk that Ferrari are going to protest the RBR exhaust bodywork....hope it comes to nothing
