Andial 3.8
Guys
I haven't seen acceleration times on an Andial 3.8 in any publications (Porsche or otherwise) so I thought I would post these. The unofficial times fully recognizing potential flames.
Timing is based on Passport G timer. Best of three runs. This was not abused like magazine tests I have witnessed. (No 5,000 RPM drop clutch starts). After testing I noticed the wing was set at maximum down force so the MPH could be higher with less rear wing drag.
0-30 1.53 seconds
-40 2.38
-50 2.90
-60 3.43
-70 4.60
-90 6.15
-100 7.53
1/4 mile 11.45 @ 131.9 MPH
Quite frankly these times show my track experience against Venom 600's, F-40, and Lingenfelter 427 Z06.

JJB,
A beautiful, amazingly fast car. It's threads like this that make me want to spend money and go faster. BAD BAD BAD. But sheesh... 132 mph? Oh... I gotta have me some of that!

That's no car...that is a rocketship! Fine job getting your TT fully sorted out there JB, you are da man! 
Let's get this Beast into Excellence Magazine...one caveat, they will want to know your secrets such as the tube frame, the complete CF body and all those titanium parts, the complete Lexan glass teatment, the nitrous, the JATO bottle, all your tricks JB!!!
You are going so fast in the 1/4 mile you may need to consider a drag chute...or maybe some 15" rotors...you may be able to snug them in around those 18" BBS wheels.

Thanks for sharing.
From these figures I would estimate 0-200kph in 10.5secs - very quick for a "heavy" 993tt.
How accurate do you rate your measurement device ?
This site has some figures for most of the Porsches (inc some tuners) measured by German mag Sport Auto http://www.einszweidrei.de/
Car looks great
I thought that one was supposed to use a different front spoiler (big bottom lip) other than turbo S (I presume that is what yours is) to counter the down force on the rear produced by the GT2 wing.

I've taken about 100 lbs out of the car due to aluminum doors and hood. Its around 3200 with spare and 1/2 tank of gas.
I demolished a big front spoiler taking my car off the trailer and went back to the turbo S and it seems to work as well with the Gt 2 wing.

I checked the Andial website and read the Excellence article. Seems very complete.
Are you running the dual mode chip (race gas / street gas).
What are GT1 turbochargers? Are they modified K16's or are they K24's?
Have you had your car on the dyno and if so can you share the results?

The ecu (chip) is a dual programable unit that many of the factory GT2 race cars used. It is in set up on low programs for 91 octane, and high for 100 race gas.
The turbos are from the GT1 street car. They flow more air than the K24's.
The motor was dynoed and produced 574hp at .9 bar and 620+ at 1.1bar.
The torque is over 800 NM. There are some other details Dieter asked that I not advertise so I will respect his request.

How long have you been up and running with the Andial 3.8? Was the work on your car performed at Andial? You mentioned the name Dieter and I am not sure whether he is an employee of Andial or from another outfit or privateer.
Was the dyno an engine dyno or a chassis dyno and is the hp figure fwhp?
Could you convert the nm torque figure to ft lbs?
I would like to know hp figures at different RPM's if that is info you can share.
Sorry about the 100 questions. I wouldn't ask if it didn't sound very interesting to me.
Thanks.

The motor was engined dynoed at Andial. This is fwhp.
The formula for newton-meter (nm) to pound-feet is to multiply by .7375622.
Dieter Inzenhofer. is the "di" in Andial along with Arnold Wagner "An" and
Alwin Springer "al".
Prior to the 3.8, I ran an modified 3.6 with over 10,000 track miles with no problems. Since it was time for a tune up I elected to go with the 3.8.
I videoed the dyno runs, the dyno sheets belong to Andial. Hope this answers most of your question.

The timing was done with a passport Gtimer which is a second generation accelerometer. Purists have some problem with it, however I find it spot on in comparing with known drag strip times. Unlike a time slip from a drag strip, the mph is measured at the end of the 1/4 mile rather than an average of the last 60 ft.

your car is supercool. I betcha when it hooks up you fell like you are being "catapulted off the deck of an aircraft carrier".
I would like to do the same thing some day on my 993. I have the engine transmission.........how much wheelspin would I have at launch.

RE: your car is supercool. I betcha when it hooks up you fell like you are being "catapulted off the deck of an aircraft carrier
Actually, the catapults are pulling about 3.3 G's according to my pilot friends. I'm probably half of that.
how much wheelspin would I have at launch.
Actually very little, maybe 5-8ft. The all wheel drive and 235/315 R tires hook better than I thought. Hoosiers would be even better than the Pirelli Corsa's. I know that the Viper Venom 650 used drag radials to get 3.2 to 3.3's. The drive train in the Porsche is engineered for up to 600lbs/ft torque. I'm close enough to that number that I don't want to underwrite drive train parts all over the road for an acceleation test.

Wheels are forged BBS race wheels, 9/18 and 11/18. No rubbing with 235
and 315 Pirelli Corsa's. Not sure of the offset, I'll have to pull wheels to let you know.

Congrats on your recent car mods.... However,
"The turbos are from the GT1 street car. They flow more air than the K24's"
This is incorrect! The Street GT1's flow an equal amount of air as the K24's. But, as you will find out, they will spool quicker, and thus produce more air at a given RPM sooner......
