This was on my kit at 14 psi, stock motor, as you can see the power band decreases at the end because of wastegate problems wich the boost was coming down to about 11 psi by redline, and also on a not so efficient turbo. The car has been in the works to try and make plenty more of power.

 

wats ur setup? boost tapers down in any turbo setup, so its normal to see lower boost levels at redline.

 

boost does not taper down in any setup. it depends on what turbocharger you are using. the correct turbo setup will allow you to pull great boost for whatever powerband you are looking for...

 

Curious to know what turbo you are using?

 

Nice numbers, here is a better version of your graph..not as bright and readable for me.

 

14psi on stock engine - you have some OO 's

 

Looks good though..

 

i guess this is a custom job? where did the manifold come from?

The turbo was a .42 trim compressor and 40 exhaust side thats why it wasnt being too efficient.

 

By efficient, you mean the lag right? Cause it looks like there is a good deal of turbo lag.

 

14 psi , wow haha ur crazy!! props!

 

props to the 14 psi man. Let me know how long it lasts...JK. Awesome numbers.

 

it lasted about 4 months but prob wouldve lasted longer, but the car got an o2 sensor problem and leaned out a lil bit and fried the rings.

 

One of the weakest parts of the tC they say..

What are you running now?

 

well now i went with pistons, and stock rods, and arp studs, new turbo 60-1 front and well see how much we can make off the stock rods. still breakign in the motor as soon as we ge tthe car dynotuned i will post pics of new charts.

 

OMG congrats to you Enrique. and Good luck

 

Good luck!

 

good luck man.

 

*shock* lol


Thats actually the same psi I ran on my car with the stock internals, but made quite a bit more HP, about the same torque. Stock ringlands dont like that much boost.
