The car is a 91 talon with minor weight reduction mods. It still appears a full street car and we are out of weight mods minus lighter wheels and seats. We are guessing race weight is 2900-3000lbs. The track we are at is at 3990Ft. the baro pressure was 14.55 so a bit lower than sea level the night we ran. All runs would hit 32-30psi and slowly drop to 26-27.
The mods are as follows:
Engine
Stock 160K engine (head/block even has balance shafts)
arp head studs
Stock head gasket
BC 272 cams
Stock intake manifold and TB
Evo 3 exhaust manifold unported
Evo 3 16g unported
2G O2 housing ported
Custom CAI
ECMlink
Pte 780cc injectors
Walbro 255
Aeromotive regulator
SBR large intercooler and piping
Gm maf
3" shorty downpipe (just past oil pan)
Urethane engine mounts
Drivetrain
Stock trans/ T-case
Stock axles all four corners
dss 3" driveline
act 2100 street disc
Suspension
GC coilovers
Stock front struts
Kyb adj rears
Evo 8 wheels
BFG drag radial 225-45-17
Now weve been playing with this car for a couple years upgrading parts only as needed. After this last go around at the track friday night we found the weak link with the ACT 2100 clutch and will be going with an ACT 2900.
We have the car pretty dialed in and we are running Q16 gas. No NOS, no Meth injection, and no e85. We got the car into the 11's pretty easy and figured we would stick with it and work out all the bugs. I will give the basic run down of the slips from friday. If im missing anything I will add it as my buddy has all the stuff. He is going to email me the logs so I can post them up.
First run off the trailer 25psi in tires
11.65 @ 118 with a 1.63 60'
Slight change in tune to lean it out half a point one degree of timing in some spots
11.58 @ 120 higher 1.6 60'
We played with the tune more with small changes and nail another 11.5 @ 120
By this time we drop tire pressure 2 psi every run from the beginging and the 60' times get slower. Shoulda seen this sign from the start as a failing clutch.
Play more with the tune and add about 2 degrees timing up in the top range
11.55 @ 121 with a 1.725 60'
This car usually will 60' time in the low 1.6s and we have hit a 1.59. So next time to the track we will get a new clutch and find the next weakest link. There is a ton of suspension parts that will need to be upgrading. Bushings, front struts, rear toe kit, maybe a front strap kit. We will try to hit the track on Aug 19th to see if we can get even better. Weve overdone our goals and know there is more left in the setup. I personally want the car to hit a 1.49 60' on these drag radials. So its a good chassis game and I strongly believe we can get it close. One step at a time and we find what works and what doesnt.
