Tuned my car today...

Heres the setup
Stock 95 ls longblock
golden eagle blockguard
drag manifold
garret t3/t40e
2.5" downpipe and exhaust
gm 3 bar map sensor
dsm 450cc injectors



I was running just about 17 psi and I used Crome version 0.6.8 to tune it.

thats an awesome number are you running that in a dx coupe or hatch?

 

Thats great man, iv been thinking about boosting an LS I have. The more I read the more I want to.

 

im in a dx hatch.. The car is just INSANE on the highway. i get no traction until 4th...most likely due to my stock hx wheels and 185/60 tires

That sucks.

 

so you did that run on 17psi ?

 

wow isnt that a lot for 450's?

 

^kinda wonderin what duty cycle is at also.
Very impressive #'s though

 

yea i'd like to know the duty cycle too...i'm probably pretty close to maxing them out. after i saw how much fuel it needed i raised the fuel pressure to about 53 psi and pulled some fuel from the map to try and keep the injectors happy.

 

So it was 17lbs of boost or is that the fuel preasure ? lolz thank you

 

yea i was boosting 17 psi.

definitly the rims and tires.

&lt; same power as you, heavier car, gsr tranny, bfg drag radials/gsr wheels = traction in every gear.

good job on the power

 

Awesome numbers!

 

thats cherry.

 

so basically 17lbs of boost is fine on a stock ls sleves.. not bad, but I remember seeing some LS stock make close to 300whp on like 12lb of boost ? maybe im wrong. Neverless nice number

 

17 psi is fine if you tune it right...conservative timing and rich air/fuel mixture are important. Also, you have to remember that not everyone has the same size turbo...so 12 psi on a slightly larger turbo may make the same power im making at 17.

 

yeah, I also topped out with DSMs...I could have been in mid-300's if I hadn't gone 100% duty cycle at 7000rms...see sig

 

Damn, 17 psi on pump gas? What's the A/R on teh compressor and exhaust housing? and what kind of wheel is inside that turbo?

 

How much psi can the stock ls sleeves hold? With proper tuning.

 

290 good horsepower but i think you can get more out of it at 17 psi.
Well i guess it depends on your turbo.

SiBirdie,
Thats my car your talking about. I made 290 whp on 12 psi with garret t3/t4 turbo with 57 trim. Willis by looking at your dyno graph you look to be running a little rich between 5400-6400 rpm. You could probably pick up some more power by leaning it out a little.

 

Willis,

What turbo was this on?

 

specs? i made 300 on 12.5 with a 57 trim 60comp 63 exhaust

 

so darin wanna tune my car now good **** man

 

nice numbers When will people understand that Boost is relative
