Well,
Bored during my vacation. The track had reopened, found my trusty G-tech, Wife was working and still no S1 to install. Soooo, In my constant love for tools, racing, and passion for tinkering with cars and motorcycles, decided to play at the track and do some number testing with my mods.
I started by removing all the gadgets and tricks and going back to as close to stock as possible. Then going to the track which is less than a mile away from my house and test the car for HP increase or decrease with my G-tech. I have already posted times before at the track so I will focus on HP gains with different things. Keep in mind that the G-tech is not a chasis dyno, it works with accelerometers and that the aerodynamics will affect the numbers by lowering the HP numbers. You need to input the car weight, so I used 3300 LBS for all passes, I am sure that the car weighted more than that but that is the number I used. But it is very constant and it works for the HP gain game. The car is an auto stick with full interiors and gas tank with 93 Octane Shell gas at the half mark, I also left the PCV fluid air separator because it is not a performance mod. Also, the computer was reseted after each mod. Again this is not a Chasis dyno. I am sure that the dyno will show bigger or smaller numbers than what I got, but I had to kill time during my vacation.
Baseline pass. Factory exhaust, K&N filter, Complete Weather strip, Silencers in place. 138 HP, Yes, it sounds very low for a 215 HP car, But remember in adition to drivetrain HP loss, this measures also the Drag effect of our PT Wall and I am messuring HP increase, It may be off from reality but after three passes it was constant by +,- 1.
Next day I went home and removed Air silencers, re-installed the BTG exhaust and went to the track. 9 HP increase in the G-Tech for a total of 147 HP in the screen but I felt the car fun to drive with just this.
Third day at the track, lower air intake silencer removed and the famous Hallman MBC was added to the equation, Set it to 12 PSI with a spike of 14PSI. 10 more Horses here for a total of 157 HP.
Fourth day into my vacation A'PEXi runing at a constant 14 PSI replaced the Hallman. 5 more horses came out in the display for a total of 162 HP. and once again my low 14 sec pass came back.
Using this math, the total gain was 24 HP increase with an investment of almost $1000.00 for the K$N filter, BTG exhaust and the A'PEXi EBC. Again, This is not a chasis dyno in a controlled environment. and the numers could be off by a few or a lot of numbers but for me it was a nice way to kill a few days. [8D]
Now I have to cruise around with the wife and kid to make up for all the days I spent at the track and in my garage. My wife says she saw more of my butt than my face and that the PT enjoyed me more than she did during vacation....[:I]
I can't wait no more for S1!!!!! Like all the other people that has ordered it I have yet not recieved it!!!!!!![xx(]
I guess you can now decide if S1 is a good investment or not. 20 HP increase for $400.00 ( 450.00 for me including shipping and the mandatory 6.6% tax for all the thigs that come here thru FedEx or UPS)
or $1000.00 for 24 HP increase in aftermarked goodies and OEM parts mod. In my case I will do both for a whoping $1450.00 and most likely will see a HP increase lower than claimed because of the other mods. But in my tradition, once I get it, I will be on the track with my G-tech on the windshield.
