Added 20hp with C&L combo! Dyno results here

Wow, what a day. I got to spend an enormous amount of time on the dyno with Project Brightmare, our test mule. We were removing the MAC Cold Air Kit and testing the gains of a C&L 80mm MAF kit, and then the gains of the C&L Plenum and Accufab throttlebody separately.

There is tons of data to go thru after 24 runs. That's right, 24 dyno pulls. So bare with me for a few days while I analyze everything. But here are the initial results. More to come later.

These are naturally aspirated numbers. We did do nitrous runs, but the numbers weren't up where they were supposed to be so I'm checking to see if any lines are clogged, or other complications and we'll test that at another time.

Thanks goes out to Dale at Custom Performance for taking a few hrs out of his day to help with the dyno tuning. His knowledge was critical to the success of our gains today.

1.) Baseline runs:
(MAC CAI, stock MAF meter, stock Throttle body (TB), stock Plenum.)
AVERAGE of 3 runs: 232.6 hp / 259.0 tq
Notes: Running pretty rich at 11.5 A/F

2.) Removed all MAC parts, installed C&L 80mm Mass air meter, with included big-ass K&N air filter, and C&L intake tube.
AVERAGE of 3 runs: 243.0 hp / 278.9 tq
GAIN OF avg 10.4 hp / avg 19.9 tq !!
A/F running at 13.8 on top end.
MAC CAI was previously causing rich condition, so this was not only allowing more air, but correcting air/fuel readings giving the double whammy.

3.) Installed Pro-M Remote Optimizer (about $170). This unit plugs in with MAF to adjust lean vs. rich with the turn of a dial. This was the only way to adjust the A/F ratio. A Very much needed tool for dyno testing. There were no significant gains with just adding this since we're already borderline lean, but this was to setup for the additional parts in a few minutes.

4.) Next installed C&L Plenum with Accufab Throttle body. We tested both 70mm and 75mm, and gains were slightly better with 75mm. So that's what we kept on the car.
It took several runs to fine tune the A/F with this full setup now. Once the Optimizer was dialed in for perfect harmony, we got this data:
AVERAGE of 3 runs: 251.9 hp / 286.1 tq
GAIN OF 19.3 avg hp and an ungodly 27.1 avg tq !!


What does all this technical garble mean you ask? It means my seat of the pants meter is directly connected to the big damn smile across my lips, that's what it means.

This car is definitely stronger. Even with extra wgt in the car, it hauls ass now. I should have done this long ago instead of the Mac CAI, but I didn't know what to get at the time, and some of this stuff wasn't out yet. So my hopes are that by posting this kind of info, it will give you better insight on what new power mods are your best options so you don't waste your money.

It's hard to find good dyno results that are conclusive, and I now hold that powerful data right here.



Oh, and if you're into peak numbers this might be of interest. Everything above was based on averages so there were no fluke runs ruining the accuracy. The difference in the best peak baseline run and the peak final run was 22.6 horses and 28.1 ft/lbs of torque.

Here's a few photos of what it looks like. I may try to polish the aluminum parts later on, if I get brave enough to try it.



Remote Optimizer. Just barely turn the adjustments to change a/f.


Nitrous Nozzle port C&L gives you.

San Man, here's the link for the Optimizer:

It is critical to tune this combo after the changes because of so many new components. You don't want it too lean or you'll hurt the engine, and too rich will waste your money on the setup and not get the good results.

The Mac CAI robs power by richening the air fuel mixture.(90 degree bend into fender causes this)

So the gains from the MAF and inlet tube are a double whammy because we're seeing gains from both the air flow of the new parts as well as the A/F ratio changes.
