Back From The Track.

[motorhead]

The day was hot!

The car was run with an open dump, 275/60/15 radials, and ~1/2 tank of fuel. The transmission has a very tight 2000 stall converter and is non-L/U. The car has 3.73 gears & brand new valve springs.

Best on 94 octane street gas: 2psi launch; 18psi boost; 30psi tires; 5300+rpm shifts & shifted into OD. Jay Carter 94 Street Chip.
R/T ... 1.719 (Hey, I am racing a Turbo Buick here)
60' ... 2.299 (Crappy tires, low launch boost, and little to no stall)
330 ... 6.056
1/8 ... 9.140
MPH ... 79.51
1000 ... 11.809
1/4 ... 14.052
MPH ... 100.07

Best on 114/110 race gas: 2psi launch; 20-21psi boost; 26.5psi tires; 5300+rpm shifts. And I placed a Jay Carter 110 Race Chip in the ECM.
R/T ... 1.904 (Hey, I am still racing a Turbo Buick here)
60' ... 2.287
330 ... 5.988
1/8 ... 8.983
MPH ... 82.54 (I accidently slipped the car back into second, days best was 83.78mph)
1000 ... 11.549
1/4 ... 13.712
MPH ... 103.81

Basically I am still having a tough time driving this car... shifting specifically, I made it onto N on one pass. It refuses to 60' because of the lack of weight transfer from the stiff front suspension. The MPH is indicative of low 13s/high 12s in most other Buicks. Since my first time out with the car it has picked up 4 tenths on street gas, and 7 total tenths on that race gas mix. MPH has jumped up about 3 on street gas, and 7 on race gas over previous bests.

I found that in absence of a spray wand setup, a water bottle with a couple of holes punched in the top is a good means of wetting down the intercooler... it is really easy if you are still missing the stock I/C fan, like me.

It was nice to see some old friends... and a lot of them were asking where my Monte Carlo was, I guess that it has made a name for itself

Any guesses on what kind of power this thing may be making?

That is horrible Even with just regular radials and all stock pieces I went 12.8@106.5 MPH. What is up with the 2.2 60 fts.? Come out with what the tires will hold.

 

[Dan Thompson]

I would think low 12's or high 11's.

Look at the section on Drag Racing Techniques on this board

Having Probelms shifting? Let the thing shift itself - it is an automatic.

The 2.2s are because of the tight convertor. At 2000rpm the tires start spinning @ the line... 2psi is all she'll hold for me. I am not too far off of your mph... I am still new at this Buick thing... The car has only been on the road for a little over a month and a half.

There is nothing like doing a burnout at 15-20psi.

 

[Dan Thompson]

What are your rear tires? How about a line lock? The turbo is stock? I believe the transmission should be in "D" and not "OD" at the finish line, if possible.

I had a old Caspers 7 position on #5 setting with 110 octane and 18.5 PSI to go 106.5 MPH with a 1.8 60 ft. on BFG 265/50/15's. My leave was 5 PSI. Don't manual shift, you can't do better than it will do on its own. Neutral huh

-Some cheapy 275/60s --- 140 treadwear rating.
-I have a rear proportioning valve bypass and s-10 wheel cylinders. I also have 12" front brakes.
-The turbo is stock, but ported.
-The car has 3.73s and it used to be a 10 second DFI car... so that is why I am manually shifting it. Normally I'd have to lift off the throttle to get it to change gears because it is governed to shift well above 5000rpm (ported heads and a bigger cam, etc.). It is not a stock BRF trans.

Ever run 13.7 with a 6-pt roll bar?! I am a ricer

 

[Nocooler]

That convertor is killing you - I leave off idle with my 9-11" and still cut 2.0's on 235/60's, and its a peg leg.

On Drag Radials ~0~ vacuum gets me low 1.9's. Any boost and the car cuts 2.7's.......I have some work to do.

And I thought I was doing bad.....


Get that gonvernor set to shift when it supposed to.

Keep tuning - you'll get there, your mph is what I run with 16-17psi with a street chip.

 

[motorhead]

I am seriously looking to gain more on both street and race fuel... but I am in a conservative state of tune as this was only my second time out with the car.

Any thoughts on the "typical" power level this car is at?

 

[Nocooler]

You don't have the 2nd pump coming on do you?

I'd say your at the 325-350ish hp with the mph your at, maybe a little less.

1) I am not totally sure if that pump is coming into play I think it is hooked up (I used it to drain the gas tank at the track [jumped the Hobbs switch]) to come on at 14psi. Are you thinking rich condition?

2) At the crank, right?

 

[Nocooler]

I'd think it bog the car with the 2nd pump kicking on. And @ the crank.

To get an accurate idea of what your car will do, get some slicks. Anything less and you're just spinning your wheels. < pun meant >
