I hope anyone who is running one of these has a good fuel system because this thing is a monster. I've been comparing some of my log files from the T76 to the ST80 and it is just destroying the T76. I've been looking at my injector pulse widths. The ST80 at 12 psi is consuming the same amount of fuel as the T76 at 16psi!!! I talked to Jose yesterday to let him know how it was performing as a rear mount and asked where this thing gets into it's happy zone and he said around 15psi. The T76 was really in it's happy zone around 13psi on my setup. I think this thing is going to fly.

It spools pretty well too considering it is an 80mm turbo with a 3.4" turbine wheel with a 1.00 a/r mounted 18 FEET away from the engine. It has just enough lag to allow me to hookup on the street with hoosier drag radials but comes loose around 90-100mph. I haven't been able to take it over 6000 rpms due to the lack of traction from 90 on, car gets a bit scary and the 2-3 shift doesn't happen until 125 mph. The data log shows me spooling up from vac to 12psi in about 1.2 sec from a 3500 rpms roll in 2nd gear, the first .6 sec of that is spent getting it to 2psi. In 3rd gear at 70 mph (2700 rpms) it reaches full boost by 80mph so it has good top gear passing power (3rd tops at at 190mph) lol.

I don't know if I would reccomend this as a rear mount turbo for a 6spd car. Maybe with a 408 and one size smaller a/r on it. For my car this is about as much lag as I would want with a street car. Some people migh consider my setup a bit laggy and it probably is compared to a good standard setup, but it's on the verge of fighting for traction as is so I don't know what faster spool up would accomplish. I without a 2step I can pre stage the car and leave on green at the track in less than 4 seconds so it spools a lot better than most 10 sec GN's i've seen.

I'll try to get some pics of it tonight for everyone that wants to see the clearance.

 

That ST80 is going to haul ***.....hehe

 

the ofi kit for the gto is a nightmare and especially considering the st80 on it, there is just no room and I am not happy with my downpipe routing etc.

The 80 is indeed an animal, before i melted the heads and gaskets it really was something to behold on the street runs i made. Insanely loud like a jumbojet

 

Yes we slot the covers a little different for the sound. The supra guys are the ones that wanted it done that way since they wanted a sound like the T51R's. We can really make them scream when gun drilled.....hehe

 

That's as bad as the guys who get cam's because of the way they sound. Ricers.

 

Would love to see some pics.Thats what I like about the rearmount there is just enough lag to get out the hole.But like you said at 90 its a fun ride.When I hit 2 for the first time with the t88 it surprised me wasnt realy expecting it to get that crazy.

 

I like a lopey cam and loud turbo. I'm a ricer?????????

 

Yes, I'm wanting to know too!!

 

Congrats man vid vid vid

 

pics of the ST80 installed

 

looks low. Put a soda can buy it and take a pic from directly behind it.....if its not too muc h trouble

 

does look low but its a big somma bitch, if you can get a picture of how its being held up too. Looks like you drilled the housing for a boost ref?

 

I'll try to take some pics during the daytime. It's about 3-3.5" off the ground so there is plenty of clearance, wish I could say the same about my y-pipe, but it will be redone. The y-pipe on my car is higher than the stock one and still hits on everything. Wouldn't be an issue except it shreds my wrap. The turbo itself can't be moved any higher but it is a non issue, it's only sitting about 1/2" lower than the T76 that was on there before.

I don't know how it's supported at the moment, haven't looked at it. It was previously supported by the exhaust pipe, the intake and the down pipe, I would assume this is done the same way.

 

I installed my t88 and got it 5" off the ground.I removed the heat shield and put a self-adhesive heatshield on the bottom of the tank.It will let you raise the turbo alot higher.I cant ever get pictures to post on here or I would post them.

 

Makes since because the ST80 is way bigger than a T88 (exterior dimensions)...........I think.

 

here are some ST80 pics I found to give you guys the idea of how big this thing is.

 

I wasn't trying to knock Zombie's install by no means.I was just stateing what I did to get a little more ground clearance.If anybody knows something about the rearmount's it's Zombie.



lol

Zombie,

did you stick with the same size intake pipe size ?
which was..... i think 2.25" ?

 

wow thats insane I couldn't picture something that big back there. I really need to get mine up higher.

looks awsome man !!

 

Vids by TM night or ban.
