it had a rajab intake before, last time when i saw a swap from that to this intake, the power curve changed from concaved with rajab to convex with this one, and from memory this intake took over at 5500 ish rpm, id have to check

Roughly less blades on turbine is more top end Comp wise 6+6 should outflow 11 blades But theres so many factors there Blade size/design

Nah grout up to welsch plugs Fine for street If youve got coin fit a bottom end girdle that ties into standard main caps and block

Exactly..put some 260s somethings in it..and enjoy the f**kin thing...

Id do headstuds. Id prefer a new headgasket aswell, then should live a long healthly life.. Cheers Darren

except you have a turbine housing and turbine wheel in the way of the exhaust flow which is the biggest bottleneck in making power..and revs..in a turbocharged motor and is more often the power/rev cap ...and not the camshaft, more duration just does nothing in that scenario apart from shorten the powerband..

Yeh im not sure, ive actually written my wording wrong... I mean theres lots more flow with the 66mm compressor upgrades, the turbine backpessure woudnt be pretty, but theres probally another 60+rwkw left(over a standard 3582 comp) of the turbine before it gives up. Theres plenty of information around on this even via xr6 upgrades and vl turbos if you look, but i never take to much notice as its not the right way to build a turbo but i know that those combos dont work on 98 oct and need e85 even on the xr6's with 4.0 of motor s to be a viable option The problem with designing a turbo that way is..yeh it makes power..but you have a comp/turbine mismatch which does a few things... Cant take timing all that well doesnt have as wide powerband as it should has a very sharp power curve onto boost that hits like a sledgehammer and then gets pulled down due to backpressure quicker turbos dont last as long That was my initial worry about the gen2 gtx 3582, the powerband would be peaky and not hold up top and need a 65-66mm turbine

the 1.06 vs .82 on gt3582 deal is really not worth it. the 1.06 is really for 3.5l/4.0l motors to kill backpressure at same hp as the smaller motors On a 2.5l to 3.0l there is a little bit of power gain on kill, but absolutely f**kloads of lag..you might as well go up in turbos size as you will get the same lag..and heaps more power...

The hotsides makes lot more with the 66mm upgrades.. Guessing its that unless, the extra compression matt runs upsets things a lot

Hes auto/loose converter and 3.0 single cam

The return flow setup shown on top of the page,is the same setup Vl turbos where running in the 90s and still some today.Core depending ..cant be to bad for flow as they run 9s on 30ish psi with autos and 3582s Cant be to much pressure drop slowing them down.. Cheers Darren

Your doing it all wrong matt..cant you find a old Nokia phone to put next to turbo not a sparkplug...lol..

i thought there was a dyno sheet on last page?..

6boost has done the twin gate versus single test i believe, i think he said it wasnt worth it? goleby parts was doing same test or have to by now maybe? cheers darren

depends alot where oil supply is taken from in different engines, and how old the motor is for a start as if it will be 5500rpm..lol i like lag aswell..least you get more road speed up for traction..but i dont like needless lag and unmatched turbos..lol

The worlds best customer service and reliability.(turbonetics) .joins the worst..lol i am not worried about them making 500..they will..the 3582/ 11 blade 67s already do that. its how they make it cheers darren

i agree..my mates leaked from seals straight up... i wonder how many pt problems are caused by using dash fitting drains..maybe they are worse than other brands when they get "backed up"

another mate has one..490rwkw on 30psi..manual..single cam.. runs 144mph.. its on song at 4000rpm..on a single cam with massive cam at 30psi,, it just starting to tick over t4 splitpulse would be way better..

Yeh my mates vl made 450rwkw though glide on 30psi with just that 67mm comp wheel upgrade on 3582 ..went 140mph make f**kloads more with exhaust off...but went straight to 40psi...and maxed out 2 044's laggy though... you really want a pt6466 .82 t3..

And theres more than a few cases of people melting turbines to the housing doing it on 2.0's..lol

not on 3.0's ....

And vls have run that close to that with 3582's with the KTS 11 blade gtx billet wheel on less boost.. my mate went 140mph on 30psi with stupid retard backpressure(full exhaust with gate plumbed back), others have gone 143 on 32psi.. with .82s and backcut 3582 turbines

yes and yes

last one i saw was 655rwhp on 36psi through a auto sohc rb30, 144mph ish traps at 1300kg ish What you and your mate are missing matt, is you are talking T3 housings, doesnt matter how good the turbine is..your pushing shit uphill from 450rwkw onwards really on a 3.0...okay on a 2.0.. its t4 time if your starting from a clean sheet of paper..this will never change your giving up spool..and power Out of interest..the p trim turbine is hardly anymore efficient than a 3582 turbine in the real world without being backcut alot and the 65mm old precision turbo turbine is a turbonetics f1 wheel

Anyone looked at the new procharge hiflow turbos..gt37 turbine/68mm billet comp in a 35 frame..very GT3794 ish, not sure on price cheers darren
