Getting There, my new best

[esinger]

Well, I when to the local dragstrip with a IC buddy and we ran our cars.

Last time I went my best was 8.985 @73.906 MPH. My boost was at 20 Lbs and no added timing.

Here's my slip from my last (and best) run today:

R/T .624
60' 1.990
330 5.508
Time 8.424
Mph 84.99

That's with 24 Lbs of boost, around 2 degrees of timing advance, 7.2 % fuel pull from the TT chip, 93 octane on street tires (Pep Boys futuras) and akly set at 5 on the knob. Hooking up is obviously a big issue, but it feels good and I think it has more to offer.

Great MPH on that run!
That should equate to around 13.3 @102 - 1/4 mile

So all you did changed was timing and boost?

Edit:
What were the 02's?
Post your mods.

Great Times

Great MPH on that run!
That should equate to around 13.3 @102 - 1/4 mile

Correction considering he ran 84.99 mph in the 1/8 that should equate to 12.8-13.10 @ 103-105 in the 1/4 depending on traction. Considering that most descently tuned turbo buicks will gain 20+ mph from the 1/8 to the 1/4. Congrats you have a bonified 12 second hot air on pump gas. Last time I ran high 12's I was @ 84.65 mph in the 1/8 and 104.37 in the 1/4. That was with a 1.927 60ft.

Excellent! Good to know! :biggrin:
My calculator must be off ............ :frown:

 

[esinger]

Thanks for the encouragement!

I've been thinking about the traction issue on the launch, unfortunately I wasn't able to build much boost at all without going sideways (which I did once and ran a 9.4 second at 83 MPH). The Turbo Tweak chip can be adjusted for first and second gear timing, I'm wondering if I retard the timing for 1st/2nd gear would my 60' times improve?

My next run may be next weekend. I'll see about working it up to 25 Lbs of boost. Fuel adjustments and boost seem to make the biggest difference. Increasing the timing didn't net me much extra.

Another Left out mod:
HR Parts Poly motor mounts

YO ERIC


you need to come by the house and get my slicks and use them next week. Since i blowed a head gasket today at the track


BTW congrats on the great runs. I think we'll get there with it tuning just takes some time.



I have some heads you could have ported

 

[esinger]

Thanks Pat, may take you up on both the offers. The only thing I'd be concerned about with throwing slicks on is wheel hop. As you know my rear end is pretty much stock with the exception of the shocks.

Congrats to you as well for running your personal best of 7.3 seconds in the 1/8th. You said you were going to break the car going into the day, so succeeded in both your goals

We didn't do too bad for 77 degree weather (although it felt 80).

 

[turbo6x2]

Great job Eric, the stock rearend should be okay for a couple of passes. Do you have a posi in the set up? You say you were going sideways, was this from pushing when trying to build boost? You might need to upgrade the brakes or go to a trans brake set up. Not a fan of the transbrake thing in first, tired it twice this weekend and it was way too weird. I guess I'm just a foot braking type gal. LOL I guess if I can hold 15#'s against the foot brake without pushing through I'll take it.

 

[esinger]

Hi Jamie,
I upgraded the car to posi (Eaton) about a year and a half ago.

I went sideways on the launch, built up too much boost and when I let loose from the foot brake the rear end started swinging out, so I let up and nailed it once I straightened up.

What kind of brakes you have that can hold 15 pounds of boost?
