Power With A Td06?

[Roy]

The 3040 had a bigger A/R housing then you would normally expect. Im still pretty sold on the old Trust turbos. And whilst on the same dyno they were tuend by different ppl.

How can you say the power delivery is snappy by looking at that graph?

[`nigno]

Poor example graph IMO.

there is no way the HKS 3040 is that laggy. Simply no chance its only making 240rwkw @ 5800rpm.

There is something very much wrong with that comparison

considering my GT30 (garrett version) delivered power much smoother than that 25g graph.

Its not about making the numbers, its power delivery.

The older Trust turbos power delivery is snappy and that causes wheelspin. Yeah it makes the car feel fast as it comes on boost with a rush, but the GT30 i had was so progressive you didnt even know it was feeding in from 5 psi to 20psi

How is it a poor example graph if its an almost identical setup, the same dyno and two comparable turbo's to those in question ?

Secondly...

If its not about making numbers, than whats your issue with it making 240rwkw @ 5800rpm ?

That should mean nothing to you, its all about power delivery isnt it ?

The graph above shows the td06 makes approximately 80kw further peak power output, a quicker peak boost mark by approximately 1000rpm (taking into account your claims of excessive lag) and the boost is held more constant through the rev range and fades less and more gradually from the trust turbo even though the Garrett item is running more boost.

Regardless of lag.... the garrett turbo has peaked its power output and the graph has started to flatten out before the td06 has even peaked yet. Reduce the size of the exhaust housing to combat this monster lag that is unacceptable in your opinion. Thus reducing the peak output of the turbo, ur even further behind, might spool quicker, but now your (lets say for arguements sake) 100kw down on the trust turbo due to the garrett no longer having the room to deal with the exhaust gases required to pull bigger numbers.

Throw a good set of rubber underneath that and deal with the wheelspin coz the benefits are clear in my opinion Snappy VS Crappy...

Oh come off it, are you still drunk from Sunday Night's escapades?

If your saying there is nothing wrong with a HKS3040 making 240rwkw on 20psi... then you still either drunk or hungover. There is something seriously wrong there

You know damn well my Garrett item was on around 4000rpm give or take and it was making a lot more than 240rwkw on less boost with a factory head

Either give more specs of the car with the 3040 (like the fact it probably dropped 2 piston rings), or retire the comments on that comparo as IMO they are totally incorrect

The bigger A/R will simply induce more lag, peak power should, if anything, be more.

benigno - i aint gonna get ringht into a reply to your post as i dont believe the comparo graph is anything near accurate based on what i've seen with my very own car.

Also if you want, have a look through this thread:

in particluar these items.. which i might add are not running upto the boost leve the GT30 can without being out of the efficiency map either

You tell me the comparo graph is accurate now

Its totally wrong... and as you can see the Garretts here, whilst make 20-30rwkw less, are making much more power, much sooner, much smoother

There are more graphs around here, i'll leave it to you to go find them

cheers.

Hehehehe nah I can see what your getting at man and I agree thats underpar for a 3040 just having a stir, and trying to make ppl see that just coz they are slightly older doesnt mean you can write them off completely.

For the price and specs, they do a damn good job at delivering the goods and im very happy with mine

[Roy]

Yeh, I agree that the 3040 isnt making the numbers it should…but the car still ran an 12.1 at good mph with that setup so it was making reasonable power.

Anyway, I say it still makes for an interesting comparison…I have a casual look from time to time and compare ppls Garret setups with the 25G setup and not many make the same peak power, and making the power that this thing did at 5,000rpm.

So whilst the 3040 is under done a little, feel free to post up any GT30 on a std RB25 with baby cams…id be curious to see some making more power. Actually, id be curious to see an RB26 with 2530s and how that compares to the 25G plot????

[Roy]

Actually, found this old info of B-man old car that ran the exact same 3040.

Boost starts at 3000

3500 = 5 PSI and 80 rwkw

4000 = 8 PSI and 112 rwkw

4500 = 20 PSI and 200rwkw

5000 = 23 PSI and 260 rwkw

5500 = 22.5 PSI and 270 rwkw

6000 = 22 PSI and 310 rwkw

6500 = 21 PSI and 323 rwkw

That was an earlier turbo setup on my white car Ash, the 25G is Brett's old setup.

Either way you look at it, with 3 motors + cars with near identical bolt ons (Greddy plenums, 550cc injectors, aftermarket turbo kits, intercoolers, cams etc) Brett's car still kicked the shit out of mine or Brendan's car.... and Brendan's had a rebuilt motor.

Made more power, and did alot more MPH than either HKS 3040 car.

The 25G comp wheel is between the GT30R and GT35R - similar inducer to a GT35R but smaller exducer

[LTHLRB]

how would a TD06-20G go with lag and peak power?

[siba33]

im interested in the Td06-25g seems like a good turbo and looks to be good for the 300rwkw im chasing!!! if you dont want lag then you will have to give up the high power yer?? also what cams are suitible for this turbo?? i have an RB25DET cheers

[LTHLRB]

You can try have a good turbo setup that doesnt lag that much. Which will be an ideal and very fun setup

[SirRacer]

one of the leading turbo experts here in nz swears by the mitsi turbos (trust or greddy dont make them)

ive seen plenty of examples on evo's where the td06 turbos are flowing better than the garrett gt equivilant.

they are both a good turbo and im sure both of them would do the trick and nicely. i also agree that new technology isnt always best. its more about getting a turbo that has well proportioned wheels/housings etc

the garrett gt2540 is a great example of a new turbo with poorly proportioned wheels and housings and subsequently its a lag monster.
