shake down dyno of the new setup.

Wow, just saw this. You sure that dyno is callibrated correctly? [img]tongue.gif[/img] Congrats on the new #'s! [img]smile.gif[/img]

I'd question the boost gauge before questioning the dyno.. have you used more than one gauge and still shown only 5 psi?

Regardless, impressive numbers from a 60 degree mill :D

same boost gauge Ive been using for 2 years. It WORKS.

We made 3 runs all same results. Other cars there also made correct numbers so no mistake.

The numbers aren't impressive by themselves except by the littel amount of boost it took to reach them. Ive made 336 rwhp/397 rwtq in the past with a much smaller turbo but it took 3 times more boost.

eh I guess I'll post some pics [img]tongue.gif[/img]

Congrats on the numbers!!! I told you it would work ;) .

I'll be using one on the 3.8 I'm putting together for the the fiero project and will put it through it's paces at around 30psi \m/

BTW, I've got the bottom end ready to go in to be balanced. Balance shaft is becoming pratice material for welding cast!

[Tiago]

Hehe. I just read something from the LS1 peeps that the dyno was reading about 20 rwhp low :eek:

Actually the dyno was exactly on with MTI's dyno... which, if anything, is said to give a bit higher numbers.

also still learning, does a bigger turbo just increase boost? or is a big turbo at 5 psi better than a small turbo at 5 psi.

i am thinking 5 psi is 5 psi regardless of the size of the turbo, but I'm still learning and am not sure.

Nope. 5 psi on a baby little turbo is not going to move the same amount of air as that same 5 psi on a big turbo. Its at the same pressure, but not nearly as much flow. Air=Hp.

Cp </font>[/QUOTE]The mass flow rate will of course be different due to temperature differences.

Do you have any idea what the difference in intake temperature was between the old turbo and the new one at 5psi? Also, if your boost guage is in fact correct, it would seem that the old turbo was out of it's efficiency range at 15psi.

whoa... I am with James, if I didn't know you I woudl be calling B.S. as well...

but hey everynow and then our cars can surprise us.

I thought, maybe just maybe if I was really lucky I might be able to hit a 14.9 without really buying anything for my car, then I ended up pulling a 14.4 out of my *** [img]smile.gif[/img]

Very impressive Tiago... Definetly good numbers, I'm impressed [img]smile.gif[/img]

[kamarozrule]

is this kit going to be for the 3.8 as well? and if it has a similiar setup, what kind of gains will you be expecting?

What is this some sort of cruel joke, the only picture of the turbo doesn't work.

[nocutt]

Nice numbers...however something isn't right somewhere :( ...assuming you even have a VE of 90% at 6K RPM and flowing almost 400CFM (turbo) which will equate to about ~30 lb of air/min your max tq will never be that high...Yes I don't doubt the HP, but the TQ???, then again since hp is a mathematical derivative of TQ then the whole thing has a hole...ask for a recalibration!!

[BLLDOGG]

aawwwwww!!!! picture dosnt work. more please :D
good job though. seeing these numbers, i may just have to switch from the supercharger side to yours. [img]graemlins/burnout.gif[/img]
