I took my car today to the dyno and I'm not exactly to happy with it, though maybe I'm asking too much?

My mods are:
Skunk2 Plenum Spacer
2.25" test pipes
Vortech kit with 3.12" pulley


Everything else is stock including the catback. Also, my car is a 5AT.

Here is my dyno:


This was with 23* of timing advance after 5K more or less on 93 oct ( supposedly...lol ). Also, no matter how much or how little timing...the graph would always look spiky...Doesn't matter if it was 20 or 15 or 12*. The power would just go up or down but the spike would always stay.

What are your thoughts?

 

BTW- I also have NGK Iridium 1-step colder plugs gapped to .042.

 

Spacer hold up well with the Vortech?

 

seems like it...

 

i was at 383 rwhp with hfc,hks exhaust,440cc injectors,3.12 pulley. I have a rev-up motor with a 6 speed running on up-rev (osirus). Yea i wasnt real happy eaither. now im running 2.87 pulley, 600cc injectors. Im now at 429 rwhp. i was happy at first but now it just ok. Dont get me wrong it rolls,but NEED MORE.....lollol

 

Here is a before and after.

 

I wonder how much would an exhaust give me. I'm running the oem exhaust and it's kinda puny imo.

 

You sure your 5AT is holding up OK? The jumpiness really seems tranny related..other than that looks fine, A/F's are in check.

 

every dyno reads different. 10hp to the wheels gain isnt bad. did you just get the numbers from the dyno or did you actually get tuned there?

 

I don't think I have a problem with it because the gears apply with force, no slippage.

I tuned it on the dyno myself.
