you mean the AF sensor/sniffer they stick in your tailpipe right?

nice gain but do you have a before dyno run?

 

yes, it's the one they stick in the tail pipe.

stock numbers are on the dyno chart i just posted. this chart diplays my before and after. they didn't put my best stock run on there, but it's really close.

 

duh, i just need to open my eyes

 

Carlos, gets yours done yet?

 

Wow, 400 at the wheels that's amazing.

 

Yeah, that's pretty good for a 996. It's all in the high end, but I'm starting to get used to how to get the power out of it. It's actually not a bad thing as if you keep in under 4K, the car completely feels stock.

 

Have any of you guys added any aftermarket gauges to monitor boost and air fuel?

looking for reccomendations....

i'd prefer one electronic display that shows everything as opposed to several small mechanic gauges. i can't seem to find anything like that.

 

nah, not yet. been too busy, just got back form a trip and i have a track event this weekend (sears pt). i didn't want to have it installed and have something possibly go wrong far from home. i want at least a 2 week shake down before i go to the track but I CAN"T WAIT!!!

 

if you want a digital dash and no data logging then get the AiM MXL Strada. it hooks right up to the ecu and has 8 analog inputs. i believe you can do boost and AF ratio.

 

i don't think that will do boost or AF. looks cool though. not sure i'd want to go that crazy on something I'll probalby install in the glove box. seems like that would be better suited for a race car/bike.

 

Deputydog,

Congrats! And nice gains, and it seems that the power curve on the 3.6L motor is a little more flat and "torquey" compared to the 3.4L evo motor...which is important and good. Definitely get that "lean" condition worked out...can't be good for longetivety. Let us know how it feels to run thru the gears on it now with the SC

PS: ...was on the phone with Tom Chan at TPC thursday of last week, in the conversation he told me the typical HP and Torque numbers for their kit (which had also been refined over the years) is around ~415 RWHP *corrected* (give or take 10RWHP) and ~375RWT** ...that enormous torque figure (in which 90% of is available by 3K even rpms) is why that test drive in "Foreign affairs" TPC charged C4s felt and WAS so fast. I can't imagine what a 3.6L C2 should be like...I will let you know though I may purchase it as soon as this month coming (Nov.) if a certain transaction happens for me...

 

I'm sure their uncorrected HP numbers are about the same. However, that TPC kit is a torque monster. And all that extra power seemed to be availalbe at almost any RPM. I still think the TPC car is faster than mine as it's building more HP and TQ at far lower RPM's. It felt incredibly fast.

The TPC kit works, without a doubt.... In a perfect world, I'd love to have a roots blower with GIAC programming and bigger injectors. I really like the way that TPC kit boosts down low and has all that extra torque to spare.

However, the more I delve into the way TPC delivers fuel and manages the computer, I'm not sure it's the best option for engine longevity. The 7th injector works, but there is a definite possibility of the center cylinders getting more fuel than the outer cylinders, which will cause badness in the long run. Not to mention allegedly, their piggy back computer does not have the ability to retard timing under boost and they compensate by adding more fuel. I'm not a mechanic nor an expert, but those things concerned me. I know for a fact that the TPC is functional and fast, but it's just not managed as well as the EVO kit. Or should I say the EVO kit operates closest to the way the factory intended the engine to run. My personal preference would be the EVO engine management with a roots blower.

With that being said, a roots blower definately changes the characteristics of the car so much so that it doesn't feel like a porsche, more like a vette which isn't a bad thing, but i could see why it would turn some porsche purists off.

I am very happy with the EVO kit. Marc at Bert Smith Porsche Motorsports in St. Pete did a great job on the install and has been excellent with the after sale support (few small hiccups as any big project has). Not to mention Todd and Nate at EVO always take my calls and spend as much time as needed to get my questions answered. They've been great. EVO's customer service has been some of the best that I have encountered in the porsche aftermarket industry.

The EVO kit does rock. Once you get the rpms into that magical 4K sweet spot and above, the car really sings. Get it into full boost, and it pulls and pulls. One nice side benefit of building boost at higher rpms is that the car drives very normally around town. Other than a small whine from the SC, you'd never know it was there till you hammer the throttle.

I give the EVO kit two thumbs up. Very pricey mod, but I'm not dissapointed.

Now how do we get some more HP out of this thing without blowing it up?

Oh, they're still checking on the AF reading. Everybody is still under the assumption that the AF sensor on the dyno is out of whack, but they're going to put it on the porsche computer and data log the AF readings under boost just to be on the safe side.

 

Here's a post I put over in the turbo forum regarding gauges.

what do you guys think about these?

i figure two of these would work on the steering column without looking goofy. might be easy to read there as well.







they make them for boost, AF, ect....





here's a link to their square digital gauges

Good numbers on the SC DEPUTY and I could see your smile ear to ear when stepping on it. Regarding the gauges Yes I was looking at those gauges the other day but didn't post because I was at odds, it would have to be 2 seperate gauges 1. EGT and 2. SC boost and I couldn't find those guages in a pair. I lean towards something that I could put in the glove box out of site and pull out when needed when I wished to check engine parameters. Heres an article on the EGT gauge as a ulturnitive to the A/F gauge.

In your picture (above) of the gauge in front of the speed and RPM there is a dead space what a great place for where the readings should be, built into the dash.

 

i would prefer to have a single box as well. i just can't find anything that isn't a boost controller as well, which would be worthless to me since it's not a turbo car.

i keep going back and forth about putting them in the glovebox, but these gauges are so small that you could put two of them on top of the steeting column and it probably wouldn't look out of place. might be kind of cool to see what's going on with the car as it's happening. my only complaint with analog gauges is that they tend to be bigger and harder to read at a glance. most of the boost gauges go to at least 20psi, which is still to broad for this application and our piddly 5-6 psi
