amazing build randy. cant wait to see it run in clayton!

 

That's gonna be a lot of fun, Steve. Wow were closing in on 3 weeks!

 

800 on 27 psi is pretty good. I made 800 on 29 on 3076s running out of fuel. I told u that setup is not gonna cut it for ur goals. How did you end up redoing it ?

Post some videos and 60-130s and get those drf run files to overlay dynos.

 

Mark, was that standard correction, SAE correction, or uncorrected? The screenshot looks like Dynojet's uncorrected numbers - just so any comparisons are apples to apples.

layinback - car sounds like a beast... cool vid on the dyno, too. The exhaust tips look like coffee cans! I bet it's loud...

 

It was a long time ago. I usually use standard correction which is the default from the Dyno shop I use.

 

Here are 2 dyno runs. 700 hp @ 25 psi and 800 hp @ 28psi ( It's not 27 psi

as I had originally thought.) Mind you, this was on e70 in 94 degree heat.

The car made 650 whp on 93 pump!


I did a couple runs last night. The 160 mph run and corresponding 5.16 was

a 4th gear pull!!! I wanted to show the flexibility of the 3073s.

The 5.18 run was with a 3-4 shift. I'll post some 4.9s soon. I've done a

few practice runs with the rolling anti-lag and I have no doubt this car will

do mid 4s......maybe even low 4s. I'm 100% confident in a 9 second 1/4

but I think I am a 10 second driver

 

How is the driveability of the car using the ProEfi? I am looking to get one for my 996tt very soon. Did you get the traction control working? I heard it is amazing!

 

We are still working on drivability. It just takes a little time but I'd say it's

90% there. Most of the problem is with the 2150cc injectors. Hindsight is 20/20

and if I had it to do over again I would def go with the Bosch 2000 inj. But be

prepared to shell out some bucks for tuning. And remember, this is a far cry

from tuning a stock ecu. This is more like creating a stock ecu from scratch and

then there is the business of tuning the 5 stage boost control, traction control,

launch, rolling anti lag etc....


We have enough fuel system for 1200 hp. I would encourage anyone considering

a build like this to overkill the fuel. A Bosch 044 handles the daily driving and up

to 5 psi of boost and after that, the big boy magnafuel 750 takes over.


Traction control is AMAZING! Even at 28psi there is very little drama in 1st,2nd and

3rd. There isn't a huge sacrifice in power for traction with the ProEfi. The car just

rockets forward. It has to be driven to be believed

 

It's deafening. We couldn't video until we found some ear protection.

Those coffee cans are actually 3 inch Supertrapps w/ 5 inch outlets. They're

straight pipes. Sounds better then any 5k setup but the drone is like being

3 feet from an amplifier at a Black Sabbath concert. It's no Miltek

 

What are you hitting for injector duty cycle with those things @WOT? Are you able to get a smooth idle?

 

Would the 2000cc make that much of a difference over the 2150cc injectors?

I am debating 2150cc (for another car I am building) though question the driveability of the 2150cc which would be overkill for something a touch smaller but without the same headroom.

 

Maybe 50-60% duty cycle at WOT.

Working on the idle. So so when it's cold. Idle is a little rambunctious initially

but settles into 950-975 most of the time.

As I've mentioned, it's gonna take some logging and back and forth with my

tuner to sort the last 10%. It's very drivable right now but def needs the

rough edges ironed out

 

Continue to question the drivability of the 2150cc because they're a nightmare

to tune! The Bosch 2000cc injectors are the ones, trust me.

 

come up to bowling green ky this sat evening for test and tune. 5 to 9 pm . ill show you how to launch that monster at 6000!!!!

 

If you launch this Porsche at 6000, you'll need an axle
