Finally had the opportunity to get the Cutlass on the strip to do some shakedown runs. It was a terrible day for drag racing today, 95* 70% humidity, and a very hot track. But those conditions meant many people stayed home, So i had the chance to make a ton of passes.

The biggest issues of the night was ridiculously high intake temperatures and non existent traction. At the start of a run the IAT's where about 133* and 180* by the top end, so I know that was absolutely killing me. The massive amount of low end torque the motor makes made launching an interesting task. The only way to get it to hook was a John Force burnout and stalling it to 2k. anymore RPM the tires would blow off and massive tire shake would happen.

Weighed 3,750lbs w/driver

Right off the trailer it went 12.77 @ 109, 2.02 60ft, spinning bad.

bigger burnout and rolling into the throttle went 12.78 @ 109, 2.08 60ft, still spun a bit.

wimpy burnout and a 1500 rpm launch went 12.76 @ 108.5, 2.06 60ft, spun like the first pass.

All those passes I was logging air/fuel ratio and correcting on the next pass. From here on out I got the AFR nailed so I worked on the launch.

Big burnout, 1500rpm launch with an instant pedal 12.285 @ 110.6, 1.82 60ft, no spin.

Same setup as before except 1300rpm launch, 12.30 @ 110.6, 1.84 60ft

Advanced timing 2*, increased shift point from 5800rpm to 6100, made shift timing quicker, 12.21 @ 110.4, 1.82 60ft

Huge burnout, 2k launch 12.17 @ 110.4, 1.77 60ft

John Force burnout, 2k launch 12.14 @ 111, 1.76 60ft

Overall i'm pleased, I wish i could have ran it into the night when it cooled down. I know it has 11's in it the way it is, it was just to darn hot tonight. I saw a maximum of 96% injector duty cycle so I think I am limited on added addition boost until I get new injectors, but I figure with traction, 10# boost, and my hood for areo it should go 11.70's or so.

Sorry no videos this time, it was all about business tonight, but I heard form several accounts that it was the meanest sounding daily driver some people have ever heard

 

NICE... Twelve-teens isn't shabby in anyone's book!



(Well, maybe John Force's...)

 

Great times especially for the first outing and crummy air

What did you do about your fuel pump situation?

 

I got a Walbro 255 in there right now but have a second that will be going in this winter.

I'm anxious to get it going in good air with a set of slicks, I was on 275/65 BFG Drag Radials

 

wow, since i just got FIOS, i was able to read your whole build
i ended up with the LQ4, but went with a carb, given my weak computer skills, lol-i orig had a turbo 400, but built a 4l80e, which is in it now
i used the vette front acces. drive, and a D1SC Procharger for a vette, with a Procharger Intercooler
my best time to date (with a turbo 400) was 10.68 @ 126, 9.6 lbs boost under the carb-took it on a 400 mile trip, milage was around 17, but had the carb setup rich-FI would def clean it up, but 60 MPH @ 1900 rpms is pretty cool
i used the stock trans x mem., just cut the mount off and slid the x mem under the tailhousing and welded it back on the other side-i wanted the hump in the x mem for exhaust clear
i built a stroker for it, but been to lazy to install it, lol
i would love to try FI, use a throttle body and have my intake drilled for inj.
prob just switch out my aeromotive reg for an FI unit, keep the same A1000
pump-yea, you got me thinking of FI, lol
did you ever chassis dyno it?

 

Nice times Ryan that thing has some 11s in it for sure. I would imagine you will pick up some mph as well if you get some better air.

 

Congrats ryan nice times especailly first time out and conditions.

 

Very nice, I have a 3800 lb car that will get a supercharged LS engine setup at some point (1951 Merc).

 

Ran 11.79 @ 114.5 1.71 60ft tonight with some better air and tuning

 

awesome

What afr and timing are you running at?

 

11.05:1ish most of the pass and 17.5-19* varying a lot with IAT.

In a perfect world I would be at 11.30-40 and 22* in first and second then 20* for the long pull in third. But after running the 11.79 I didnt want to tune anymore, just run it!

 

wow. congrats

 

Sounds like you have your tune dialed in. Is this on pump gas?

 

you`ll be getting kicked off the track if you run much faster!

 

Pics or this car isnt real

 

Yup pump gas 93 octane, heres the proof:

Only my 11.88 pass, the 11.79 vid is LONG!
