Questioning turbo size

[michael evans]

I am questioning if the turbo on my car is to big. The Turbonetics 6668BB was on it when I bought the car two years ago. It is not listed on their site, but is on Jegs.com and Summit.com .

I wonder if I should buy a new more suited-for-me-turbo and resale this one or get this one worked on ?

The car dynoed at 534 HP and 704 FP at only 23 pounds of boost.

I saw a couple turbos listed at half the price that is in my horsepower range.

You are making good power. What is it you don't like? Is it laggy? Doesn't do good at track or bad street manners?

 

[michael evans]

Fun car to drive on the street.

The track times are not that great (7.54 ET 1/8 mile ).

The Turbonetics 6668BB

this is not the turbo to run 7.5 1/8ths with.its capable and designed for much more power.it really has too much ex wheel which creates a slower spool but less backpressure.compressor runs out way before the ex wheel but all in all you would be running low 10s to high 9s to run it out,so you can turn it up or swap it out to a much faster spooling turbo.i personally would turn it up and run it hardthen see if you like it or want a change

turn it up!

its a 1000hp heavy turbine wheel mated to a 700 hp heavy compressor wheel.

 

[michael evans]

What can be done about the slow spool up ?

It is a 2007 unit I think.

Do they make a lightweight or or newer design wheels that allow faster spool up ?

 

[michael evans]

turn it up!

Might have to talk to Brain Lorenz and see about doing just that.

Was told that it is capable of upto 35 pounds of boost.

 

[Kip]

What mph in the 1/8? Also are your dyno numbers rear wheel?

 

[michael evans]

Yes at the rear wheels on his machine.

1/8 mile is the same as a friend of mine with a super stocker ran with a 6.61 ET (88.??? miles an hour).

 

[Mr.Spool]

Do they make a lightweight or or newer design wheels that allow faster spool up ?

yes there are alot options.tnetics has a billet bb61,62,64,even a 69mm is lighter and will spool faster and make 2/300 more horsepower!

 

[Mr.Spool]

What can be done about the slow spool up ?

you could swap out the turbine wheel to a smaller one,but i would just change the unit altogether

 

[michael evans]

Need to call them tomorrow. There times are 8 to 5 PST it is 12 to 8 my time though.

 

[Mr.Spool]

Was told that it is capable of upto 35 pounds of boost.

depends on the the combo,but a safe bet is easy 100hp

heads cam and compression?

 

[Mr.Spool]

converter?

 

[michael evans]

converter is a 2500 stall NLU. Transmission has a brake.

converter is a 2500 stall NLU.

what is the 60ft with that stall?thats way to low for a 68 ex wheel
