New best- 13.6 with a basically stock TR

[neat]

Last Sunday the girl and I took her TR to the track. It's basically a stock 87 with 122K on it. The minimal mods are:

Walbro 340 on stock wiring
Test pipe in place of cat
Adjustable waste gate rod
Casper's audible knock

It's got all the stock stuff from 87 still; valve springs, timing set, MAF sensor, etc...

We put some 100 octane in the tank, turned the waste gate rod to 18 PSI, and headed to the track. After 1/2 a dozen passes the car was running pretty consistent low 14's at about 96 MPH. We let the car cool for an hour or so and then removed the stock chip in favor of an ancient Kenne Bell chip that was bought for the car way back in 1988. After installing the chip, reconnecting the orange wire, and letting the ECM re-learn everything, the car went 13.6 @ 100 MPH. I attribute some of the gain to the cooler car, but the most noticeable difference was that the boost crept up to 20 PSI.

Everything felt really good, I can't wait to put a hot wire kit, cold air kit, and a real boost controller on this thing. With some more tire, I really think it's got super low 13's in it the way it sits right now, if we could ever get a nice cool day here in NC to run the car.

Anyway, I'm pretty happy about the times and thought I would share.

Throw some valve springs and new injectors in that thing and watch what happens at 20psi. That popular mechanics article from years ago, where they tested old hot rods vs. new and the TR represented the transition between the old and the new. With some race gas and 22psi on a stock TR, he ran 12.50's.

Showdown!

more details on the run

street tires or drag radials?
60 ft. times?

Dry rotted 215/65-15 BFG radial TA's, no drag radials here, lol. 2.0 sixty foot time on the best pass, 2.1-2.3 average. 8.7 @ 80 in the 1/8. It's just shifting into OD at the line, so I think I need to run it in thrid, and I might rig up a converter switch for the next track day.

For some reason, when I power brake it at the line, it bogs down on the launch. Even if I launch with 6-8 PSI, there is a bog, then about 5-10 feet out, the car comes on and goes like Hell. I watched Kelly run the car a few times, and in that first 5-10 feet, it's belching black smoke pretty good. I think for some reason there is too much fuel right off the line and it's causing the bog, then when peak boost hits the fueling is on the money and the car takes off.

I am going to hook up my Tuner Pro RT and measure the O2 volts on the launch next time we go to the track.

The weird bog was there with both chips, so I'm not sure what's up with it. Any idea's?

That's a cool article man! The Regal wasn't second to many in that one!

The chips are adding too much fuel with throttle position. The stock chip and the KB chip has no compensation in it for power braking. Try one of Red's chips. They put more fuel in with rpm rather than throttle position.

That makes perfect sense, thanks for explaining it to me!
