Big Single V Big Twins (~500+rwhp)

[Lithium]

Is it a twin or single entry T4? And if its twin, is the manifold a split pulse one?

Single...

Ahh ok On my wish list is a twin scroll 1.06a/r T4 for if I keep going with mine.... one of those would be intensely cool I reckon!

good results paul, definately a more track friendly setup than the old turbos. I wouldnt mind seeing a comparision to Cerberas dyno as well with the t04z.

As per that table there were 3 styles of turbine housing HKS optioned for that "GT2835" series of cartridges .

Firstly were the T25/28 FLANGED IW GT28 housings in 0.64 or 0.86 A/R .

Next were the T25/28 flanged non gated GT30 housings in 0.61/0.73 etc etc .

Last were the T3 flanged GT Pro S GT30 IW housings in 0.68 and 0.87 A/R 's .

Mm 900 , will look at that later .

For the record I seem to remember see pics of std GT35R cartridges in T04B twin scroll T4 flanged turbine housings , don't know how well they work though .

The one Geoff liked was the Turbonetic F1-35R .

Cheers A .

This is pretty much the result I would expect when comparing a single 650 bhp turbo with twins capable of 760 bhp.

Wouldnt mind seeing this done again but with a GT3566-82R. Most people dont know what they are though, or that they exist

[discopotato03]

I do , it's an otherwise normal GT3582R with a T04R compressor wheel grafted in .

In Garrett speak it would be called a GT3584R because the T04R compressor wheel is ~ 84mm OD and 66.7mm inducer diameter which is why the Americans would call it GT35"66"R .

They are a "wildcat" as in Garrett don't make that combination available . The one they do offer is the T04Z which is similar deal but in a larger center section with a larger diameter shaft and a T04 P trim turbine .

Cheers A .

Personally I thought the twins would make a lot more top-end than the single. I'm guessing they need a bit of headwork and optimising before they sing a song.

Precisely

i think ryan1200's rb26 is a good benchmark for twin's with 2530's

though i do love single's

I never noticed that, thanks

Yeah am aware of those, a mate of mine has something along the same lines (an FP GT3586HTA) on his EVO but didn't really justify the extra lag over a GT3582R. I think if I were going to go up from a GT35R, I'd start looking at the GT40 series turbos which is essentially what the guy with the EVO is going to do - either return to a GT3582R or shift to a GT40xxR.

Ive been in a lot of supra's with different turbos, so far the best one i feel, was the 3566r one

Its a shame your mates evo doesnt have a 2J - i think he'd be ok with that turbo then
