Just finished dynoing a friend/customers 2005 Turbo S 996. Pretty cool car and the K24's definitely blow away my k16's. Do I even need to say anything about those brakes!!!

We added the Prototype Agency Power Exhaust, Forged Diverter Valves, and K&N Flat Panel Filter. Strapped it up and gave her hell. Same variables as my 996TT. NO ECU mod yet. That is being reflashed and should be running again tomorrow or Tuesday. Will repost as that should add another 70WHP!!! This is on 91octane too.

are the AFRs supposed to look like that for stock? Max indicated 15.1 ...isn't that on the lean side?

EDIT: just noticed that was during very low RPMs...high RPM AFR look to be right around high 12's low 13s...

 

Thats when you first start rolling into it. Most cars idle 14.5+ or under light load. When you load the car, A/F starts dropping, since the injectors are starting to supply more fuel (pulse width). But it does look a little lean up top regardless.

 

That's strange for a completely stock car...I thought closer to 12.5 was supposed to be where it needs to run?

 

Green is boost and black is AFR.

 

So was it about 450 awtq and 440 awhp? If so, still not quite as much as your car is it dan?

 

yeah about 440whp and 450TQ with no reflash. We had to reset the dyno so hopefully the configuration is still spot on. I had 450whp and 480tq i think it was about. But i have a reflash and everything else. He is basically stock with a exhaust and k&n filter. So with the Upsolute we are doing, that car should be at like 510whp and 530tq. We will see.

 

Do you have a dyno slip before you added the exhaust, K&N, etc?

Even though this isn't the sexiest thing to say with all the exotic hybrids out there, I think just strapping on standard k24s may be the best solution for most of us.

 

Hey Dan, appreciate your info and insights. That base line on your X50 should be about 382 to the wheels. Is that exhaust and BO`s really giving it 60whp more?? Did you baseline it without the mods to get a true wheel HP figure? This could skew your flash numbers BIG time. I`m just curious.

 

DAMM awesome numbers without a flash, car looks so nice, minus the sport techno's for me

 

mike you cant state a baseline unless you have the same Dyno, same parameters, and same conditions. Some read higher and some read lower.

No we did not do a stock one as the dyno was in use. We wanted to show what the Upsolute reflash does. So we decided to add the simple bolt ons, which add about 30HP. The reflash will be the big one to show the difference with and without

 

OK Dan that makes sense. That way you will definately know what the Upsolute chip will make in terms of HP. Does Rene have to tweak the program to take in account the BOV`s?

 

We are running Forge Diverter valves. Designed to strictly hold the boost more constant then the factory valves which leak. So does the ECU tuning need to reflect this mod, no not really.

 

Bringin this back for topic.

We got the Upsolute back and it appears there is some controversy.

The X50 should have 50 more HP then a stock TT right? If so then our car dynoed at 330 stock so this should be 380 stock. With a 20% drivetrain loss that would make the cars FLYWHEEL HP at 456ish, right? So, since we bolted on the Fabspeed Exhaust, Forge valves, and K&N flat panel, that would at max add about 20-30 HP. Bringing in theory the cars WHP to about 400-410ish.

The initial run of this car put down 444WHP and 449Torque making about .8-1.0bar of boost. See dyno on page 1.

The redyno of the car yielded the EXACT same A/F ratio and made about 1.2bar. It put down 457whp and 482torque. Same dyno parameters, conditions, etc.

So... Either the Upsolute flash was wrong, impossible, or this car was already flashed. It was most likely already flashed with GIAC as they quote on sites about a 50/60 gain. That would bring it to the numbers of 441 and 449. So reflashing it with the Upsolute which is more aggressive brought the numbers up a little. We are trying to still figure this car. The owner bought it from a dealer used so we dont know what was on it before. So it seems i was wrong in my first post, but who knows as Upsolute is comparing data and will get back to us

Dotted is before and solid is now.

Dyno done today 11/21/06

 

Nop! X50 are rated at 450PS and others at 420PS, 30bhp difference not 50. As I said on the RUF 550 thread this car was already remapped.
