They are REALLY laggy, If I were you Id get the XSpower T61. Supposidly it spools like stock twins but can make like 490WHP on pump

 

thanks for the info on the T70

XSpower? didn't their turbo's split apart at the compressor housing? :wtf:
I saw a few threads about those xspower ebay turbos, and the reviews were not very good


I'll prolly save up for a turbonetcis 60-1

 

My xspower t61 does not spool that fast. I have never ridden/driven a tt supra, but comparing to my friend's tt 300zx, there is huge lag with my t61. If the tt supra and tt 300zx are comparable in spool, then I would say you were misinformed about the xspower t61 spooling like stock twins.

I have not had any problems with my turbo yet though. I've had it on for 4 months now, and I will let everybody know if I ever have a problem with it.

 

Well my XSPower T70, I measured and it compares almost exactly to the Master Power T70. With my TT headgasket, it spools very nicely, I am sure its because I have a .68AR exhaust housing. My spool starts shortly after 2k rpm and shortly after 3k rpm I am at my full boost of 9-10psi.
I think the 4" inkate and 3.5" downpipe help as well.
Just my 2 cents.

 

We put together 2 NA-T's using MP T70's the automatic made 341whp @ 6psi and the 5speed made 544whp@25psi. Full boost before 4000 rpm. I had the XSPower T61, AKA a T70 on Ebay on my SC300 auto. The turbo had .84AR T4 hot side compared to the .68AR of the MPT70. Spooling was a tad slower than the MPT70's

Stainless steel turbo manifold
Tail 46 mm 5.8 psi spring (green) with 2" dump pipe
3" down pipe
tanabe racing medalion exhaust
4 inch intake (turbo inlet)
intercooler 24x12x4 bar and plate
stock maf (hot wire type) is on the pressure side
walbro high pressure pump
stock head gasket
boost gauge
spark plugs denso iridium heat range 24

I went dyno:
first pass was 341 rwhp at 5.8 to 6 psi (boost controller was on but not set).
Second pass was 335 rwhp at 5.8 to 6 psi ( boost controller complete off). A/F was between 13 and 12 at dyno which for me is acceptable at this boost level.

A/F with innovative wideband controller shows avg between 12 and 10.5 on the street.

544WHP @ 25 psi on pump gas. should have made more IMO but was limited by having only one walbro fuel pump. Also need to do the fuel pump ecu mod, ad a fuel pump and upgrade the radiator. ( car would over heat during a 2nd consecutive pull on the dyno )
I hope to make more than 650 on race gas and a more aggressive tune at the projected max boost of 32 psi

SC300 NA-T bad ending

 

Is a turbonetics T62 roughly the same as the T70?
(from the above pic, the T70 looks a bit bigger then the 60-1)
But I think the numbers are exactley the smae when comparing turbonetics/garretts to Master Powers

 

T70 is actually a 69mm compressor, so yes it is bigger than the 60-1.

 

my xspower t61 spools at about 3.5k. I think TTs spool close to 2.5k. Huge difference but i rode in cars that didnt spool till about 4k so im not complaining. Does those 1.3 tt head gasket make the turbo spool faster compared to the stock hg?

 

i have it, and it gets max boost around 4k, sooo yeah, i redline at 6200 so its pretty gay

 

Mine starts around 3000 and hits the 6psi pretty quick, so that sounds about right with what others have posted.

Im running NA auto rear end so the short gearing means i dont really notice the lag.

 

top gear on an uphill - i make boost at 2500 rpm!

just trolling. But on a flat surface and i gun it in 1st gear...starts to spool around 2.8k and hits full boost before 4k. I'm only running 12psi.

 

I thought the T70 turbo was a 60mm turbo no way its 69mm my Greddy T78 is a 66.5mm and its way bigger than the T70 which I compared it to.

Where did the 69mm info come from?

 

Different T70. You are thinking about the Super T70. Those are around a 60mm turbo with a T3 1.15 A/R housing.

These T70's we are refering to are 69mm with a T4 .86 A/R exhaust housing.

 

I may have missed this but has anyone measured the XS T61? If so what "name brand" turbo is it closest to?

 

yes many people have measured the t61 and it is a 69mm turbo.

The XSPower T61 is similar to that of an old T series Garrett T70, which is a 70mm compressor. The ACTUAL measurement could be the same, since the XSpower turbo is based off of old garret stuff.

 

But most people with the T61 (Xs Power) are making power similar to a Garrett T61, are they that inefficient?

 

Haha, most people that by a T61 don't have the budget to push more power than what a 61mm can make. That is why they are buying the XSPower brand in the first place.

Personally I purchased one to push to the limits, and the only thing that wasn't name brand on my car was the turbo and the manifold. I was running close to 750rwhp at 28psi on E85 with mine. Too bad the turbine seal on the XSPower turbo's are junk, and many have had problems with them going out quite soon, including myself.

 

xs power and master power both suck b/c they are weak and always break. Spend your money right the first time and you wont have to worry about anything. just my .02

Here is my thread
http://www.supraforums.com/forum/showthread.php?t=499951

 

do either of these brand make dual ball bearing 69-70mm turbos?

 

No.

BTW, I recommend Master Power over XSPower.

 

Last time i saw, the t61 from xs power is a 65mm i believe.. or a 66mm... but definetly not a 69mm... it makes 550whp on 25psi on a stock motor...

 

Believe what you want, but I have two of them right here, and both measure 69mm.

This as even been discussed on clubna-t where they sell them, and there are several pictures showing measurements of 69mm.

 

So hows mark only making 550whp@25psi?... how many lbs were you running on that pull?

 

Exactly, along with everyone else who has that turbo. It just doesn't add up.

 

First, Mark was running it on a GTE, and was with an AEM.... add like 30-50whp for ported head and exhaust he has that 3" he sells as well... So i can easily see about 650whp with cams and ported head at like 27psi... But idk where the 700-750whp comes from, and i bet that turbo starts being defficient at about 29psi or so..

 

How about running E85 and insane timing? I don't mind blowing up my motor, I have 6 more engines sitting in my garage. I was on the edge with E85.

 

I guess your tune up might just be the deal. Idk your crazy dude, its my bday you should send over one of the GE's to my house.. ill pay shipping..LOL.. Is crazy though...

 

Ahh, just thought of one more thing. If Mark is running a TT, then he is also 8.5:1 compression. I am around around 8.9:1 with my NA-T.

 

Edit:

MP T70 .68 A/R 27psi

2.5" hot IC piping, 3" cold

AND? Are you saying you have this turbo? Doesn't mean much if you just post a random graph. Also, you do realize your A/F was approaching the 13's for 1000rpm on that run. Even if your spraying meth thats still getting pretty lean for running the amount of boost you would need to make that power.

 

It's a .68 undivided hotside

 

mine was a .81 housing.

So more proof that these turbos are capable of 750rwhp.....if they hold together.

 

Where did you find an .81 housing? I also have the .68 housing and would like to go to something bigger. Is there a housing that is swappable with the "T70" housing or did your's come "factory" with the .81 housing?

 

I'd like to know this too. Only options I've seen for the MPT70 are .68 and .96

SuperRunner, Was it a divided .81 or undivided?
