91 California gas and 18.5 psi of boost today

(No correction value, straight dyno dynamics number!)

Finally upgraded to a good third party Blitz Dual Solenoid Boost controller, made a couple finishing touches and came out with this.

I actually think I could have hit 420 today, but had to leave the dyno early for some other commitments, I will do another pull next weekend if I have time.

Next on the agenda is

22 psi on mix
25 psi on mix

Are you gonna be tuning that forklift and boat? What about that 930:)

Your cell phone takes terrible pics

What are the y axis torque numbers (i.e. what are the 2 lower tic marks).

You gotta diversify in these markets!

The Porshe will be getting a GT35R...(shhhhhh) ha ha

---

I will post a better graph.

The X Axis is 1000-8000 RPM

Y Axis is 500 HP/ 500 TRQ

Car was over 320 for a while on the pull, when boost came on it slams at 305 ft lbs and carriers out from there, dips slightly under at 7200

PS, at night in 3rd gear down shifts on the fwy, even if I go easy I get some tail wiggle and wheel spin, haha, had a bit in 4th when I got cold one night.

I am running 255 40 17 aired down to 25 psi (RT-615)

Probably going to go to 17x9 (have 17x8) and using NT01's all the time.

I only drive the car once or twice a week anyways.


I will update this with more pictures in the next couples weeks as I bring this car to a close

-carbon fiber hatch lexan
-two new racing seats
-auto power racing roll bar
-porterfield pads
-ducting for brakes
-power steerling oil cooler, and engine oil cooler

any other suggestions?

***Also any suggestions on seats for a 6 ft 1 guy? *** I have low seated fixed rails

Steve,

Your dyno seems right on the money based on SR20 3076 dyno dynamic readings here in Australia.

Have you considered trying E85?

P.S. Hopefully, I will have a twin scroll 3071 (dyno dynamics) to compare in the not too distant future......I've been saying that for the last 18 months....haha.

Gut feeling is it will peak before 7200 rpm whereas your looks like it keeps on climbing.....or certainly not tapering off anyway......as you would expect with a 3076.

The first time I clicked on this thread I thought someone went crazy and put a nissan motor on a shifter cart...... lol.

After you get the carbon/lexan hatch combo on and take your car to the track make sure you post your feedback. I've always been curious if the lightened rear-end has any negative effects because our cars are already really light back there.

I love your car, we have the same taste when it comes to modifying cars.

How do people cool a ball bearing in a 930? I've seen some run small coolant systems just for the turbo but it seems like a waste. Can you run oil for cooling as well as lube?

thats a good question Bill and i never though of that. I plan on using a bullseye power on my 930 motor in the future(no coolant, yay!)


Nice numbers there Steve. Love that red and blue machine on the floor! ; )

I'm just about to reinforce the rear strut towers and convert a 930 racecar to coilovers for a customer. It will be on the dyno tomarrow though...CIS. It has a programmable cold start injector to add fuel at higher boost levels. We'll see what she makes.
I can't believe you have a 930...damn. You gotta get some regamaster evo, TE37 or SSR Professors for it, rauh welt style.

You can run oil through the water ports of a BB turbo but you need to use a restrictor on the outlet to slow the oil down. I recommend ~ 0.100" orifice. Porsche customers have been doing it for a long time with success. If you do build a separate cooling system for the turbo you need to make sure it is set up properly to maximize the thermal siphon effect.

Attached are a few pages from the presentation I gave at the SEMA show this year.

The damage to the retainer on the third slide can only occur on turbo sizes GT25R - GT35R because the ball-bearing cartidge uses a plastic retainer. The bearing cartridge on GT37R and up is metal.

I forgot to mention.......the entire presentation (Turbo System Optimization) will be posted on the www.turbobygarrett.com (http://www.turbobygarrett.com) website by the end of the year.

I look forward to tuning that thing too, Ill post more on that car once it's all back together in a bit. It is Mike Kondo's the owner of the dyno's, I supply the Nissan custys and he does Porshe, VW and Audi

Of course Pauly.

:26:

Need to get a couple more parts so I can say "I'm done" with the car before the end of the year.

Who am I kidding, I am a car guy, when are we ever "done" with a car.
