Just came back from the DYNO!!!!

[adham]

i know this is the wrong section for this but nobody seems to look at the DYNO section
ok i have a 2000 trans am with MAC headers, high flow cats, slp airlid, K&N, flowmaster catback, and free mods.
the dyno used was a DYNO DYNAMICS DYNAMOMETER
I only put down 294rwhp and 328rwtq
i have 115,000 miles on the car
is this about right?

[Sarge]

Actually quiet good...dayum...look at that RWTQ....screw RWHP...RWTQ is what moves you forward...dayum good numbers....Is this an A4 or M6?

[adham]

A4

[Capster78]

Thouse #'s are kinda low if you ask me. Id expect it to be in the high 320's low 330's. The RWTQ isent to far off. A car with that many miles... who knows. thats almost 20k miles a year. That is alot of driving!!! If you ever wanted to get serious into moding this car id definatly do a rebuild, thats just me though.

Hey Capster...when are you coming to have a Shiner Bock?
Nah...I disagree...this guy is an A4...they locked the convertor up....those numbers are great IMHO....

[Hurley711]

2 words....Stall Convertor

[Sarge]

Yup^^
3200-3500....new car....beast city....

[adham]

whats a good stall converter?
any suggestions?
so this is supposed to unleash some power?
can someone explain more please?
thanks

[Capster78]

Id be carefull. That transmission has alot of miles on it. And by throwing a stall converter on there you are puting alot of wear on an already prety worn tranny.

A stall converter in basic broad terms puts the motor in its power band and keeps it there longer. when you hit the gas with a stock converter it will start accelorating around 1500rpm's or so.. When you have an aftermakret high stall converter it will store all that power untill about 3,000 rpm's and let loose. Its almost like droping the clutch in a stick.

[adham]

ohhhhh..... i see
does it get weaker in the 1500-2900 rpm range since it will not drop untill 3000rpm???

[adham]

i think my o2 sensors are fucked up
dsoes this make any difference other than fuel economy?

[Sarge]

Yes....if the O2's are reading lean they will instruct the computer to dump some fuel at the problem...result...crappy gas mileage and performance...you throwing any codes?

[adham]

i did throw those codes before
the 2 sensors were bad
then that code went away and didnt come back

[adham]

he said it was running a little rich
i dont know exactly but he said it should be around 12 (air/fuel ratio)
mine was 10-11 i think...

[adham]

i didnt mention that the first run was only 276rwhp or something like that
he said it was because the knock sensor came on because of the new headers
the 2nd run was somewhere in the low 280's
the 3rd was the 294
basically it went up like 15 hp every time
who says it wouldnt have gone up the 4th and 5th time???

[baseballss]

i just had mine dyno tuned about a week ago, i got 332 rwhp and around the same for torque i cant really remember ( i need to get a copy of the sheet) thats damn strong for just LM2 exhaust and slp lid.

[adham]

that just makes me feel that much better

[allanmontoya]

i think my o2 sensors are fucked up

Hey i recently gutted my cats and i feel a big difference and my service engine light came on of course but those this mean i would have to get some of the o2 sensors from SLP (i think) that are used for cars with out o2 sensors?

[adham]

o2 simulators???

[allanmontoya]

yea that o2 simulators.. well with those will that better my fuel econmy since they are telling the comp that my cats arent there?
