Going to the track on saturday

[19Cutlass94]

Like the title says, im going to the track this sunday to see what she runs with the new set up, motor and exhaust. when it was completely stock, it ran 16.6. any guesses on what itll run?

Any tips or tricks you guys have for running as well? When I ran the car when it was stock, I was still spinning through first. The track just got a new surface so hopefully traction will be better. but anything you guys would suggest doing or not doing?

[Superdave]

just using street tires?

I usually go easy on it in 1st gear to avoid spinning, once you are over 20 MPH then go WOT.

Shed as much weight from the car as possible

[19Cutlass94]

yeah im using street tires. At this poing Ill probably be running with my winter tires, Dunlop Graspic GR-2's.

I normally take everything out of the car except for seats and everything out of the trunk but amps cuz I dont wanna deal with the wiring. With all the dynamat Ive got in there im guessing the car pobably weighs 3500lbs as it is.

Wow, spun that much? I guess you do have a higher FDR. Are you still untuned with a cammed 3400? I'm guessing 15.9... lol I dunno.

I got my best time by rolling softly into the throttle, but that was because it would bog slightly if I just floored it (bad O2 sensor). Don't brake torque it, I got horrible times when I did that. Don't run 1/4 tank of gas unless you KNOW that your car won't suck air, cause mine sucks air at 1/4 tank and is slower than at a FULL tank!! 1/2 Tank on the gauge should be fine, and really is less than 1/2 tank anyway.

When I was staging, I would let the AC run to keep air blowing through the radiator and engine bay to prevent heat soak. It was hot there though. I didn't shut the car off because I figured that would heat soak more than if coolant was circulating.

Also once I got going and it shifted into 2nd, I would pull it back into L so it would hold 2nd across the finish line instead of up shifting right before. That way I got a better time. I'm sure power wasn't building much but it was still pulling and faster than an upshift. I don't know if you can do this with your FDR, you might bounce off the rev limiter. I know I would now before the 1/4 as the car is a lot faster than when it ran a 16.0 stock. So you might want to hold it in 2nd and then right before 5800 rev limiter upshift into D so it can shift into 3rd. That will hold the gear more and since you have a modded engine you can use that RPM and that will also help when it goes into 3rd it will be starting out at a higher RPM.


The 1-2 upshift should be ok, they tend to go pretty high stock. Mine even hits the rev limiter sometimes.
The 2-3 upshift is the one it short shifts, so try the suggestion above.

When i ran the car stock, 1st gear was like 45mph and i ran through the traps in 2nd at like 85 or 86 or so. I cant do that now. 1st gear shifts at 40mph and second gear shifts at 70mph. Id be into 3rd gear by the time i crossed the finish line. Im just gonna try holding 3rd and see how that works out. it revs through the gears a hell of a lot quicker than the older motor, so I know its deff faster than the old set-up.

But yeah car is still untuned with the cammed 3400. Since i fixed the vacuum leaks it runs much better. Im just hoping nothing happens between now and then. Although I still have a problem with the lifters so i duno if im getting the full duration and lift that i should be getting.

yand the only reason i spun that much before is the tires were worn pretty bad and the track was kinda slick. Im hoping for low 15's but i duno this thing is a boat. But I can tell you it loves second gear.

[IsaacHayes]

Ok, thats about what I was. So you had a 2.94 FDR too? Now you don't??? You'd have to have a 3.69 FDR to shift out of 2nd at 70mph. Top of first would be 37mph.

[geldartb]

i hit low 15's with mine on the stock engine 15.2 to be exact and 15.4 in 90* humid weather.

so you should be able to hit high 14's.

if i can bang low 15's with just a free flowing 2 1/2 from the manifold back and a 65mm t-body and a crap milzy tune you should be good.

[19Cutlass94]

I think I have a 3.33FDR. But I cant be postive. It was really strange because the shiftpoints changed when i put the new motor in. Not even touching the transmission. I think its just the new motor having that much more power to get through the gears faster?

Id LOVE to hit 14.9 or better. LOVE to. That would be almost 2 seconds faster than stock, which is a fair amount!

[IsaacHayes]

It shouldn't short shift you... If anything you should be banging the rev limiter like me cause you're making power on a worn trans... LOL..

Are yous sure your TPS is reading right? Maybe you DO need those ScannerPro/TunnerPro files of mine.. lol

The only other thing I can think of is the cam is screwing with the MAF or MAP or something and that's affecting shifting.

[19Cutlass94]

Its a brand new TPS on there along with a brand new MAP, IAC, and just about every other sensor is brand new ( well when it was put in last yr ) But I do know that i onle have like 10 inches of vacuum at idle as compared to before. But Ive been trying to track down vacuum leaks for the past couple months, and i still theres one leak somewhere.

Other than that, Ive only hit the rev limiter once and what was when it was spinning through first. Other than that, its never hit the limiter.

[geldartb]

Jon hit 14.9 or 14.8 i cant remember with the pos milzy cam he had.

10in of vac i think im topping 6-8 at idle.

[WS6LOVE]

at what rpm do you launch?

[19Cutlass94]

if I launch off anything but idle ill spin the tires pretty bad. Even off idle they spin a little bit. Last time i went i was launching off 1500rpms.

I think i lost about 2-3 in of vacuum at idle between the two motors.

[19Cutlass94]

Just got back from the track, and not what i expected at all. All I did was spin. My first run i spun right through 2nd till 3rd and ran an 18.8. my second run i gently stepped on my gas from idle, and ran a 16.3 with 24psi up front. My last run was 24psi up front as well, and i went about 50% throttle from the light, still spun like crazy and ran a 16.0.

the track was pretty slick. or it was thr street tires i had on

[WS6LOVE]

yea, fwd cars are harder to launch due to load transfer taking all the load off of the driving wheels. :P
