Sorry Brad, could not make it over weekend, Easter got out of control! Hope it comes together well, looking forward to final result.

Well there is a guy that I have been in contact with who has run 305's with 18x11 rims, 315 would be good as I am pretty sure that is what the Porsches use a lot which gives a lot of different tyre choices. I think 18x11.5 with 0 offset would fit and clear the suspension but would require +40-50mm wider guards with 315's.

Must be ok then

Thanks mate got your MMS, what is the weight limit on this bad boy?

What is the condition of the gearbox? What is included?

Inlet ports look polished.

Quality is perfect for price = looks cheap and is $1200 for a 6boost which is so highly regarded for those who have used them is a great bargain! If you think you will get the same result with one of these and a 6boost you are sniffing paint. That being said, these are an ultimate bargain for a budget build.

Do you know what the internals of the gearbox are? Is it a syncro or dog engagement gearbox?

Can you send me a photo please?

Don't care either, not my car.

Why would you want to overfuel intentionally? Using a high pressure pump at a lower pressure isn't ideal either.

Great results... more details on engine? Head work, etc. <BR><BR>What manifold is that?

A cheap manifold that wont fail... that is good enough for most. Not me, but not the point.

Yes give that 9180 a go on some pump fuel please Geoff. The only equivalent would be a 67mm S400SX correct? But from what you have outlined that is more of a class drag racing turbocharger.

Geoff, are the Indy cars running antilag with these turbochargers? Also, do they have a use program i.e. after one race, throw in bin put a new one on? A twin EFR 6258 would be cool with external wastegates... just not much room!!!!!

Ok thread revival time. Along the lines of the theme above... I want to fit some wider than normal wheels and tyres to my R33 GTR. The idea was to use 315/30/18 or 335/30/18 tyres if at all possible which would need a 12" wide rim. Question is... has anyone tried to fit or ran with a 18 x 12 rim on their R33 GTR front and/or rear??? And with what offset or guard modifications. Ideally I would like to have the same all around, but can step down to 11.5" on the front.

Are there any other EFR 9180 results yet? (Besides Sierra Sierra) And can anyone confirm that the Indy cars will be using these turbochargers and if they will be any different from the production version available to the public?

Please don't get confused here... strength and hardness are two different properties. Hardness will most likely increase as a result of cryogenic treatment due to the formation of martensitic grain structure in the steel. With increased hardness the material wll become more brittle. But this is just piss in the wind, I doubt anyone knows what steel the gears are exactly or if anyone has examined the grain structure before and after to know whether it has actually made a difference.

Hey Dan, I am finally back onto some suspension work!

Maybe if you paid him you would get a better result.

The 6466 seems like a good balance.

Decreasing the flame speed is exactly what you want to do to reduce potential of detonation in high boosted engines, especially if guys are running these engines with tight quench and higher compression.

With that smaller housing and no porting then I would not bother with a set of camshafts.

The results are similar to Paul Diemars with his GT-RS and RB26 in terms of power output. A lot less custom work involved.

How much power do you want to make? What size exhaust housing? How much head porting have you had done?
