Yeah the GT45-76 should be an animal and should be able to best both the 76GTS and match the GT42-76 and could edge it out depending on the conditions and engine size. That larger turbine of the GT45 really helps the backpressure and power potential of the unit. At low boost level (10-15psi) I suspect a 76GTS or GT42-76 will outpower the GT45 by only 30-50hp in its stock form. As the boost climbs the difference will grow since the 69mm wheel is just to small.

Now as for MM and his setup thinking he maxed out the two turbos. His car doesn't make any power because he's afraid to run the boost it will take. His tuning also sucks thats why it blows up all the time. That is why his car is an embarrassment to turbo cars all over the world.
You are the turbo MAN

Hey for all you ******* morons who don't have cars that make any power. FYI i have made more power with my car with a 1 bar MAP sensor on a stock PCM and straight 93 octain then MM has ever made. If he couldn't get more then 20-23 psi there is somthing else wrong. That doesn't mean the turbos maxed out. If you think so your a ******* idiot. You can run 50psi if you wanted to. It might not be efficient but it can be done. Don't ******* talk if you don't know what you're talking about. I've had a ******* nuff of this he said she said bull ****. You people have alot to learn. Don't talk unless you know wtf you're talking about.
P.S. MM's car is a nice setup but is an embarrassment when it comes to the power he makes.

That turbo with NO wastegate won't make more then 25-26psi on a good flowing LS1 (GT80R) period. I'm not sure where the 50psi is coming from?? If you think you can get 50psi out of a GT80R on a fully built LS1, I think you need to re-evaluate your knowledge of turbos. Hell a maxed out GT42-76 would only hold 25psi with the top port CO2 blowned closed.

YOU NEED TO RE-EVALUATE YOUR KNOWLEDGE OF TURBOS!.

A spike and sustained boost are 2 different things. I can make my stock twins on my supra spike to 27-28psi......but thats a spike and intial hit at torque. Getting it to hold is a whole different ballgame. As for knowledge....umm I think we know a tad , and we don't test turbos for some turbo companies for nothing .

Buddy it held long enough for me to say wtf is it pulling so hard for? Then look at the boost gauge while still wot and see the needle past 30. It was no spike.
I don't think you have **** for knowledge. You have no idea what you are talking about.

So yeah, put on your pointy hat and sit in the corner.

Actually no buddy. My turbo barely spools before 4k. Boost can still rise as HP does not due to IAT's getting hotter. When IAT's rise a turbo is getting to the limit. Funny how i made almost a full 4th gear pull to 7k and all it did was keep rising.

Seriously, David is a good guy and has been a big help to me; how many 9 second passes have you made on street tires and an M6? Don't be such a tool.

kissmyss01 should be kicked off by now right??? 50psi on a LS-1 with a 80, oh thats a good one.
You have probibly built some of the fastest turbo cars on earth huh. In fact I heard that kisssmyss01 invented the turbo, thats where the vast knowledge comes from. One of the only guys on the board to "blow the welds on the intake" lol.

Funny how i'm right and all you guys can do is make sarcastic remarks and you can't prove me wrong. HAHAHA
I didn't say 50psi would be efficent. It would probably make less power then 30 psi would. All i said is it can be done and that your theorys are incorrect.
Mighty Mouse has not maxed out either one of those turbos. Which just prove's my point even more.
As for my car and it's "spike" I called it a "spike" because boost went higher then i wanted it to. It did this because my gate didn't open due to a melted vacume line. Which means if i set my boost where it hit it would have stayed unefficiently.
Not only do you guys not know what you're talking about. I guess you can't read either.
Oh and another thing. It's funny how none of you guys have any cars that make any power. HAHAHA

Kissmyss01, this is your first warning, take your cursing shotty attitude out of these forums or youll be looking the ban stick straight in the eyes.
No need to take it personal. you can have civil conversation here even if you dont agree with what everyone is saying.
im curious to what kind of power you make if nobody here makes any power. Must be alot to claim to know it all.
I dont think you get the concept of turbos running out of air.
