New Mods...New Dyno Numbers

[PureVenom]

Well, I have put a couple new mods on my car. Sold the 2.76 upper and replaced it with a 3.10 upper. It is a lower boost pulley in preparation for getting a 6 pound lower pulley and a port. Basically, I lost about 2-3 psi of boost with this pulley until the 6 pounder...then I will gain 1 pound over the last setup (damned inefficient eaton).

Anyhow, I also picked up an SCT BA2800 MAF meter as a trade for my stock meter that was needed on another saleen supercharged 06 GT for the shop. He needed mine and replaced it with a 2800.

So, we put the car up on the dyno and got it dialed in for the new meter. Needless to say, I no longer max out the MAF (the 2800 is good to 750 rwhp )

So, here are a couple graphs for you. If you look at the SAE corrected numbers, I gained 2 rwhp running less boost and a different MAF. The STD corrected numbers I gaind 8 rwhp. If you look at the actual HP put down at the wheels...the uncorrected numbers...I picked up 41 rwhp and 16 rwtq.

Numbers:
Uncorrected (actual numbers): 491 rwhp / 486 rwtq
STD Corrected numbers: 470 rwhp / 476 rwtq
SAE Corrected numbers: 454 rwhp / 450 rwtq

As you can see, I lost torque with the lower boost...but the gained/maintained HP level made me a happy camper. Not to mention, that 491 number (which is 497 when smoothing is 0 ) really made me feel good. lol Can't wait for the 6 pound lower and port (or 6# and whipple if this web deal goes down. )

How much is enough to feel a difference in power for you 03-04 guys?
I'm wanting to add some power after I get everying tuned up and in shape to handle it but I don't want to waste money on mods where I might only gain 15 rwhp.
I remember with my v6 an extra 10bhp made it feel like a new car. lol

Just curious if you guys "feel" a faster acceleration with small bolt ons or if it takes another 30 rwhp to notice anything different once you're at a certain hp level.

I jumped 30 this summer when I went from a safe tune to a custom dyno tune. I felt that difference a ton. I also felt the difference when I changed pulleys as I could feel that I lost the torque.

When I went from my stock pulley to my 2.76 (~370 rwhp to 432 rwhp) I actually could not feel the difference. However, that was related to the tune as it was a mail order one. I later did a custom dyno tune where I picked up a mere 15 rwhp and about the same torque, I could really feel the difference.

In summary, depending on the tune I get, I may or may not feel the difference. If the tune is right, I can feel the change. Then next change should be in the 75-100 rwhp range...or more if the right parts are acquired...and I am sure I will feel the difference.

Steggy Stage4? That setup will be awesome, especially when you recieve my Billetflow TB.

It will be a stage 4 if I go ported...there is a guy local that has a 500 mile old stage 4 that he is replacing with a whipple since he blew up his input shaft within a week of installing the stage 4 (and 150 shot lol).
