Again differences in low end vs peak hp....

 

The real big boy is that T-76

 

I JUST WOULD LIKE TO SAY PEOPLE SAY DIFFRENT THINGS, I HAVE
INSTALLED T-78 AND T-88 TURBO KITS,ME PERSONALLY,I LOVE
THE T-88 KIT,YOU WANT HORSEPOWER THAT IS A GREAT KIT,
PEOPLE SAY ITS LAZY,I THINK THE T-78 IS LAZYIER,
NOW THE T-51R IS A VERY IMPRESSIVE TURBO KIT,IT IS NOT LAZY AT ALL,T-51 AND T-88 ARE BIGGER THAN A T-76,T-76 WOULDN'T
MAKE MORE HORSEPOWER THAN THOSE TURBO CHARGERS...

 

Is the t-51 a BB turbo?

 

IT'S BIG IN SIZE, BUT THE T-88 IS BIGGER IN SIZE,NOW HKS HAS A BIGGER ONE THAT IS A T-55R,BUT FOR ANY OF THIS TURBOS
YOU NEED THE RIGHT FUEL AND IGNITION,AND THE RIGHT TUNNER
THE LEAST BOOST YOU GET OUT OF THEM IS 1.4BAR SO THAT IS
19.91 POUNDS...

 

why is the t78 *lazier* than the t88?

forget em all and get a turbonetics y2k
haha

 

Make it two...in parallel!

 

WHY IS THE T-78 LAZIER,THE HOT END OF THE TURBOCHARGER
IS DIFFRENT AND A LOT SMALLER,THE T-88 HOT END IS LIKE A
1.35 AND IT IS A TANG/DIVIDED,THE T-78 IS A ON CENTER
HOT END,RX-7'S DO NOT RUN GOOD WITH ON CENTER'S
A TANG/DIVIDED HOT END LETS OUT A LOT OF EXHUAST ENERGY,
AND RX-7'S DO HAVE A LOT EXHUAST ENERGY TO RELEASE,
IF YOU WANT A GOOD RUNNING STREET CAR,AND QUICK, YES
A TRUE TWIN IS VERY GOOD, IF YOU KNOW WHAT YOU ARE DOING
AND THE CAR IS TUNENED WELL, YOU CAN GET PROBALEY 400HP
TO 450HP AT THE WHEELS,BUT YOU NEED A LOT OF DYNO TUNNING,WELL GUY'S YOU KNOW A RX-7 IS NOT A SUPRA...
SEE GUY'S OUT THERE PUTTING SINGLE TURBO KITS,NO FUEL
SYSTEM,AND THEY GO TO THE DYNO AND AT 1.3 WITH A T-88
ON A SUPRA THEY MAKE LIKE 500HP TO THE WHEELS...
RX-7'S ARE VERY HARD CAR'S TO TUNE,BUT A RX-7 POWER IS
DIFFRENT TO A SUPRA,BECAUSE YOU HAVE POWER TO WEIGHT
RATIO......
P.S
Y2K ON A RX-7 YOU BETTER BE LUCKY IF THE CAR RUNS FASTER...

 

Nobody ever seems to mention the turbonetics t-72. It's like the t76, I think.
Anybody know anything bad or good on the T72?

-Les

 

So you have had both and the T-78 not only had less power but more lag ?????? What is Y2K...???What type of computer do you run..?? Dynoed either the T-78 or T-88...? Thanks, Chris

 

A Turbonetics T76 is not smaller than a T88 or T51. Largest A/R you can get on a T88 or T51 is like a 1.0! WTF is that?!

A T2 turbo has a 1.0! lol

All turbos will make big top end, don't know about bottom end though.

 

go with the T-78..im talking from experience

 

dude...i dont understand anything you been saying
first off the T-78 turbine housing is tang/divided
2nd..you state the T-78 is "lazier" cause the the turbing housing is "smaller"..huh???? a smaller turbine housing puts more back pressure across the wheel which produces faster spool up

 

nope.

 

You guys should check out the compressor maps for these, at least you will know what turbo efficiency you are at for the flow you expect.
For a starter, you will flow about 50 lb/min to get about 500 HP.

The compressor maps tell you how much a turbo can flow. They don't tell you the lag.

So nobody has any experience on the T72 ?

-Les

 

I personally like the T88 over the T78, I've had friends with both turbos and I personally had a T88 in my RX7, the T88 kit is only a little more than the T78 and offers better stuff like a bigger wastegate, manifold, and it also includes a downpipe and a resonated midpipe which the T78 doesn't come with. As far as response and lag, I had no complaints with my T88, I drove mine with a 20 psi wastegate spring, so that was the minimum boost pressure I could run. I drove my car in the street on pump gas with no problems, I liked it alot.

 

HKS NOR GREDDY WOULD GIVE YOU THE COMPRESSOR MAP'S
FOR THERE TURBO'S,THERE SALES AND TECH'S DONT EVEN KNOW
AND THE T-51 DOES HAVE A 1.0 HOT END,AND THE T-88 HAS A
BIGGER HOT END THAN THE T-51,IT'S A MITSUBISHI TURBO SO
IT'S NOT CALL A 1.0 OR 1.1 OR WHAT EVER TURBONTICS CALL THERE'S,THEY CALL THERES IN CM,SO THE ONE ON THE T-88
IS A 18.0CM,AND YOU CAN AFTER THAT FOR THE T-88 A 22.0CM..
T-78 COMES WITH A 15.0CM,THE BIGGEST YOU CAN GET IS A
18.0CM,I SIZED THE 18.0CM IS LIKE A 1.35 TUBONETICS HOT END
22.OCM IS LIKE A 1.50 TURBONETICS,
AND SOMEBODY WOULD COME AND ASK WHY THEY WOULD NOT
TELL YOU THE COMPRESSOR MAP'S,BECAUSE OF THERE COMPETION WITH OTHER COMPANYS......THEY WOULD NOT TELL
YOU THEY DONT WANT NOBODY TO KNOW,THE TURBO SET UP THEY SELL IS MADE FOR THE CAR,IF YOU LIKE IT BUY IT YOU DONT
LIKE IT DONT BUY SOMEBODY ELSE WOULD BUY,BECAUSE IT IS PROVEN TO THEM IT GETS THE POWER YOU WANT,THE TURBO KITS THEY BUILD GO THREW A LOT OF RESEARCH AND DEVELOPMENT,SO THEY DONT WANT TO SHARE OUT THERE BUSSINESS.....

 

Ya, I guess these HKS and Greedy companies are out to sell to the "kit kiddies". I still don't see why they don't release the compressor maps. Maybe they don't have them either? ;-)

I have to totally build my system from scratch, including the exhaust manifolds, etc. More work, for sure. I was just looking at the T78 vs T72 maps, they both look comparable at a 2.0 pressure ratio, and 600HP.

ps: Use the Caps Lock key , unless you are purposly trying to look loud and obnoxious with all CAPS!

-Les

 

If your building your kit from scratch, don't even bother with the kits.

Get yourself a Garrett turbo (Garrett make HKS turbos anyway) like a TA45 with a P blade and 1.15 exhaust housing, get yourself a good SS manifold and a 42mm garrett wastegate and away you go. You will save a HEAP of money over the kits, have something different and something that hauls ****!

Put an E6K on it and your laughing!

With that setup ona say in a 3rd Gen, you should pull an 11 on 15psi at high 11xmph.

Just my experience....

 

I'll be laughing, I hope.
It's going to be a T72 at 15PSI in an FD with a 355 Chevy LT1
engine. I reallllllly hope I can fit that turbo in there... I hate Superchargers.

-Les ( something different FD )

 

OK... So if you have two rx7's, both of them basically has the same mods ( Street port, Haltech E6K, and all the other goodies ) and both are running about 28 pounds of boost but just different turbos ( one has the T88, other has the T51R ) Which one would make more HP on the dyno?

 

Steve, Reasons ???? Thanks, Chris

 

TO LESD,I NEVER SEEN A T-72 ON A RX-7,BUT I HAVE SEEN T-70
AND THE T-70 IS A REAL GOOD TURBO,T-72 ONLY FLOWS 4% MORE AIR THAN A T-70,BUT THE FUNNY PART IS THE MAX SPEED
OF A T-70 IS MORE 105,800 T-72 IS 105,430,AND SEEN THE COMPRESSOR MAPS,SO REALLY IM THINKING THE T-70 MAKES
MORE POWER........
P.S TO CHAD
ON THE DYNO IS HOW GOOD OF A TUNNER YOU ARE,IF YOU CAN
TUNE WELL,YOU CAN GET WITH A MOTEC SYSTEM,WITH A T-51R
OR T-88 LIKE 700HP TO 800HP,SO THEY BOTH MAKE ALMOST
THE SAME HORSEPOWER,YOU CAN GET FROM THOSE TURBOS
UP TO A 1000HP,YOU WANT TO GET A 1000HP TO 900HP
BUY A 2JZGTE THE PISTON BULL,YOU WOULD GET THAT POWER
REAL EASY,BUT JUST REMEMBER NOT BY JUST PUTTING THE TURBO KITS YOU WOULD GET THAT POWER,YOU KNOW,YOU NEED FUEL
CAMS ETC..AND WITH THE PISTON BULL YOU WOULD OWN THE ROAD,AINT KNOW RX-7 OUT THERE IS GOING TO CATCH YOU ON
A TAPPING RACE....YOU HAVE TO GIVE IT TOYOTA THEY BUILT AN
UNBREAKABLE ENGINE,THE HEAD ON IT CAN FLOW,IV HEARD
A 100% OF AIR IN AND OUT..................
