Lith, I'm going to have to respectfully disagree with you.....I havent seen too many EFR results (most are from race teams - who seem quite cagey about results), but every result/graph I have seen, shows it making similar power to the HTA3582. Your talking about a 82mm exducer vs a 83mm exducer. In reality, there isnt much difference between the two. HTA3586 / PTE6262 kinda similar.

The EFR8374 isnt that big? Its not really bigger then the HTA3582. Similar powerlevels, but far better transient response. 6262 is quite big. They love them, but they are laggy compaired to the HTA3582 and the EFR8374.

Lol

Bahaha, sounds like fun! You fixed those muffler bearings yet?

Fixed

Don't rule out the EFR8374 either. It is also a good turbo. A lot of new tech in it that no other turbo has.

True story

Agreed. I think you will be suprised at what a set of mild cams + cam gears will do... I think you should consider it, because a better cam profile CAN actually give you more lowdown torque.

Have you thought about cams - before you go looking at a turbo or while you choose a turbo system?

Back at the OP - Can you please post a list of all supporting modifications?

^ Agreed..Its all about the combo. My point is that; Is staying with stock cams REALLY a must? In saying that, I have no doubt that the two turbo's I mentioned will meet performance requirements.

I'm not overly convinced you need 24psi to crack 400kW on E85 with a HTA3582 or EFR8374. Look at 34GeeTeeTee's car. Even smaller turbo, HTA3076 and it is hitting well before 4k rpm, and almost touching 400kW. One of the two turbos I mentioned will hit the required power figure, and in a proper divded setup, it will get the response / midrange required.

My bad! I was thinking of the HTA86 compressor inducer specs! woooops! But yes, it is pritty much on the same playing field as 61-62mm compressor inducers in flow!

I vote for HTA3582R with a T4 1.06 A/R divided rear housing OR EFR8374 with T4 1.05 A/R divided rear housing. Both will get you full boost faster then any other 62mm inducer / 82mm exducer compressor on the market, not to mention the transient response + power you would make! The EFR will have much better transient response / boost recovery but requires you to get creative with packaging / fabrication as the turbo is an odd shape. Both are similar price to one another. The other option is to go even bigger, HTA3586R with a T4 1.06 A/R divided rear housing... but as they say, pick your powerfigure, then pick the smallest turbo that will do the job. I think this would just be too big, and you will loose responsiveness.

How do you guys running the EFR turbos find the boost recoveries between shifts compaired to similar turbos in the garrett range??

Haha, your a clown. Maybe Ill push it to 38-40psi on E85. Then see what it can do!

It will make around the 480 - 520KW mark on a well prepped Evo at approx 35psi. But I guess the thing to watch will be the powerband, not really the topend.

As the other guys said, sounds like head gasket issue to me!

Trying to get my hands on a HTA3586R with T4 1.06 A/R divided turbine housing... Will keep you all updated. Twin screamer pipes anyone?! lol

Haha, the bike isnt really good for long rides like that. But not in state untill 26th of July!!! I agree with you, the quicker I can get my nugget sorted, and my ass back to NSW, it will be much better. Hopefully by year end I can get a job in Sydney or something. (newcastle is dead)

^ Agreed I'd LOVE to see twin HTA's. I bet the results are fantastic!

I think the twin's are going to make a bit of a comeback fue to stealth factor.. The police these days are much too harsh, and its hard to 'hide' a big single.

Noooo~! I'd love to go.. unfortunatly my car is not ready, and I am out of state.

When you taking me for a run matty? This saturday??
