First time to the track with new combo. First run 10.87 @122. This was with 91 oct, Razor's dbl nozzle alky (set on 4), SLIC, DRs on steel GN rims, 22 lbs of boost, with 0 KR. Direct scan showed O2s at 805 at the traps. 3600 lbs car with cruz and cold AC on a 85 deg day.

The internet show "Garage 419" filmed a show on Turbo Buicks while I was there. When interviewed, I snuck in a quick plug for Razor's Alky.;) I'll try and post a link to the show when it comes out.

Left my house at 5:00AM with a 11 second car.

Rolled back up the driveway at about 4:00PM with a 10 second ride.:cool:

Life is good...

Thanks Razor.:)

Good job.. with 800's through the traps.. it can use some more boost to lean it out a bit :D :D

You have a 10 second street car ;)

91 oct. DAMN!!!! nice run
 
Nice! What cam are you running?
 
Thanks Guys.

Cam is a 212/212 roller. Timing was 24/23. short time was a 1.57. 330' = 4.46, 1/8th mi= 6.91 @99.92 mph.
I'm pondering the idea of switching out my old V4 SLIC for a new Precision SLIC. I think that the V4 may be getting to be a bit of a restriction. Don't really like the looks of a front mount. After all, this is just a "Street Car".:D

Also, for the gurus, I think that I'm giving up quite a bit with my old Art Carr 9" 3000 non lu converter. What do you guys think of these slippage numbers? Peak torque shows at 5400 on the dyno sheet for my engine.

@ 90 mph, 5350 rpms, 33%
@100 mph, 5550 rpms, 24%
@110 mph, 5825 rpms, 18%
@120 mph, 6075 rpms, 13%

Note: car has a 3.73 gear, 28" tire. Have more data if needed. Will also post this in the trans section.

Thanks.

Mike. Post up your dyno sheet.
 
Here you go.

Mike. Post up your dyno sheet.

Thanks Mike
 
I was hoping to get a good picture of what your engine is doing at 6,000 rpm. What is happening at the end of the sheet? Is 5600 where you shut it down?
 
Funny thing.

On this pull, The wide band o2 fell out of the tail pipe at about 5700 rpms. The dyno guy was watching the AF durring the pull, saw it go lean, and let off. It was nice to see that he was on the ball.;)

I do have direct scan data out to 6200 rpms on my 10.87 run. I just don't have the abillity to post the file here.

So it looks like trq is peaking at 5250 -5450 rpm. Hp is peaking at 5550 rpm.
How much drop in rpm are you seeing at each shift?
Can you give me any T/C stall figures other than advertised? True, flash, brake, anything will help?

Initial thoughts are, if you're shifting beyond 6,000 rpm, that's too high of a shift point.
The slipping does appear excessive. I've heard the AC does slip a lot on top. Can't tell you if it is more than normal for an AC.
Depending on your rpm drop at the shifts, 5500 - 5800 looks to be a better shift point for you.
You're seeing 18% around 5800 rpm. To me that seems like a lot. Has to be great for getting out of the hole and on the turbo though. 8 to 12% on the top end would be considered more normal for most drag setups. Then there's Dusty's converters.
 
Mike,

Nice easy run.........With room to spare.....:biggrin:


Congrats.

1/2 shift: 5450 rpms @ 26 mph, down to 4900 rpms.
2/3 shift: 5825 rpms @ 67 mph, down to 5000 rpms.

Conv stalls at 0 lbs boost at 3000 rpm. This stall is perfect for streetability with my GT 62/65 dbl bb turbo. This is a 99% street driven car.

Car does 1.50 short times off of a 5 lbs boost trans brake launch. The boost comes in fast. I've tryed leaving the line with 7 lbs boost only to blow the tires off.

That's impressive! Any time you can make a 10 second pass and return home with out a trailer is impressive to say the least. Fast street bikes have a tough times pulling 10's.

I need to learn to spell....:tongue:
 
Thanks.

To say that this thing is streetable is an understatment. It gets 20 mph on the freeway, and feels almost bone stock around town. I also worked hard to not have the dreaded exhaust "Drone".

Not bad.
I would try bringing up 1st gear to about 56-5700 for the 1-2 shift, unless it blows the tires away. Try out 5900 for the 2-3 shift to see if there's anything there.

Time for suspension work so you can leave with more boost. What's your suspension setup?

If I do blow the tires off, it seams to do it on the 1/2 shift. With the 3.73 gear out back for streetability, the 1/2 shift comes on real quick. Last time out the car did a 1.50 short time on a 5 lbs launch.

Car has 1" lower (and stiffer) springs at all four corners with Bilstein shocks. Rear has HR boxed LCAs, and Metco adj uppers. Air bags have 8 psi left, and 12 psi on the right. 275/60/15 MT DRs run aprox 20 psi.

For track duty, I throw on the 90/10 drag shock on the front and loose the sway bar. And that's about it.

I'm sure that a looser spring up front would transfer the weight better, but I don't want to give up the way it handles on the street to do that. Can't seem to remember what I set the pinion angle at.:confused:

So, does the converter slippage in the upper RPMs look like it's not too bad?

Thanks Mike B.
