    Info is coming, I have the 2 wheel dyno run and 4 wheel dyno run, with videos. The data is interesting, so I want to post the charts with the videos and explanations all at once. I will look to the community for questions I have with the results. I was out last week, but I'm going to make time this weekend to upload.

    I don't have any dyno results, but I have a lot more power. I now have a Fabspeedicon exhaust, catless race headers, ipd plenum, and a custom tune. The difference vs stock is utterly ridiculous (in a good way).

    same reason i don't own a turbo s. i don't want to spend allll my money on the car. dyno pulls aren't cheap. additionally, i've had the exhaust for about a year and a half, and the cobb accessport for about a year. In a perfect world, I would have dynoed multiple pulls after adding each component.

    What I do notice is that the car pulls harder not only in higher revs, but in the lower range as well. I believe this in part due to the custom tune. In addition to the noticeable hp delta, I had a guy yell out to me that the car sounded sick (in a good way) in a parking lot while I was going about 3mph.

    In order to get some factual data down, I will try to do some 0-60 runs. The Cobb Accessport has a 0-60 timer so I can use that. I did try that a while ago before the recent mods and I remember it being in the 6 second range which is slower than Porsche claims, as I do have the PDK.

    Re: Squeeze out another 50hp out of a Base Cayman?

    After my post yesterday I decided to do some quick 0-60 sampling. As i mentioned before, I was consistently in the 6 second range before... If I recall correctly-- the high sixes. I attribute this to a few things-- all weight-related (fuel tank more than halfway full, driver weight (I need to lose weight), number of options I added).

    Yesterday it was raining and I got a decent amount of tire spin from the onset, but I consistently was getting 5.8 second 0-60 times. This is about a full second improvement over my times using just the catback exhaust and OTS 93 octane tune. I look forward to trying this again when the weather gets better.

    Unfortunately the 0-60 times on the accessport are about as useful as nothing at all. The slightest tire slippage of any kind, either at the beginning or during shifts will completely change the results. You may not even know its happening and it can happen on dry pavement as well. I've seen values on mine ranging from 3.5 to over 5 seconds. Tire spin will actually make the results error read lower not higher, so it can appear you are going faster than you really are. This is counter-intuitive as you would think the spin would make you take longer to get to 60, but its not measuring the actual speed the car is moving from point A to B, but the tire rotations just like the speedo does

    Re: Squeeze out another 50hp out of a Base Cayman?

    I see a lot of discussion about the accessport from Fabspeedicon. I just installed PSE and the IPD plenum on my base boxster. I'm now thinking of buying the accessport v3 Protune. Have you guys had good luck with this?
    Thanks.

    I like it a lot. I was using the included 93 octane map for a while and it was great. Recently, when I got the headers and plenum, I had fabspeed do a custom tune. With a protune, they can exploit the maximum power by customizing based on the specific modifications you have.

    Agree about using the Cobb readings on the 0-60 calculation. Here is a 0-60 calculator that seems to be generally accurate. You can plug in various numbers and compare the before and after results. Remember to take an accurate starting weight from a car magazine and account for gas and yourself. Probably not going to be perfect but close, say maybe off by a tenth or so, or maybe even spot on.

    This is interesting. According to that, I should be getting much faster times than the Accessport is showing, even stock. Maybe I'll try a few runs using a stopwatch (unfortunately I don't have Sports Chrono) and see which method the figures align closer.

    Thanks for posting up all your feedback Marcus, it was great having you back and hearing that the additional upgrades made as much a difference as expected for you. Looking forward to cruising around with you at some point this season : )

    The 981 has a lot of potential with the Accessport/Protune, especially the Base as the throttle body opening is restricted from factory more so than the higher models. You will most certainly feel a noticeable difference and enjoy it thoroughly!

    Re: Squeeze out another 50hp out of a Base Cayman?

    What I have found interesting are the folks with GT4s in the rennlist forums who have had timing gear attached to their car and with mods found no decrease in lap times. That strikes me as quite odd. They say you feel improvements during acceleration but that translates to nada on the track. That kind of blows my mind. That is one of the reasons why I have decided to hold off on modding my car though I would dearly love to unlock the motor in the Spyder. Anyway just thought it was interesting!

    There are a number of reasons the lap times may not have come down. It's nearly impossible to compare one track session to another, especially on different days. Track temp, ambient temp, tire conditions, driver freshness, etc...can make a significant difference. I think it's fair to say that mods and a tune will make the car faster. But, without measuring the same car, on the same day, with the same driver, it's hard to use anecdotal information to make the case.

    Re: Squeeze out another 50hp out of a Base Cayman?

    I'm just gonna give my opinion here; I've done many mods and spent considerable time and money doing testing. You can compare Power / Times on different days.

    This is done all over the world with racing teams - all the time. Laptimes are recorded one day, one week or one year later and people use it to compare how their car works / runs. If you are faster... it will show up in times, be it because of power or any other factor.

    For Example, if you went around a track today with your vBox and the next day you spent several grand on headers and tunes and suspension... there obviously is no way to retest everything unless it's at another time in the future.... its not reasonable to assume that you can't come back to compare the next day or week, with similar ambient conditions.. (meaning its not raining, when it was fully dry the first time.)
    You adjust over time and if you have more power and you can drive, then it will show up in the lap-times.

    There's also the scenario where you add too much power and then you or your car cant handle it and your times show you as slower...
    But generally this isn't the case with the 981s unless you're going with some high end Turbo build-out.

    I broke down and did an engine swap for a 3.4 plus a GTS tune, headers, exhaust, plenum, throttle body and x73 suspension. That car is awesome. Still cheaper than 911 and I'm still less than a gts.

    All those upgrades make a huge difference. Add some Comp R tires and you will be as fast as a 911 when you're on the circuit. Enjoy your ride!
