Deeper into the 12's.

No changes on the car except to replace a faulty wastegate solenoid. The old solenoid wouldn’t hold boost in 3rd gear, so I’ve been running the car “tuner style” and plumbing the wastegate directly off the turbo.
Anyway, 19-20psi of boost, and weak launches all night. For the first time in 4 outings, I didn’t cut a 1.7 on my little DR’s.
Best run of the night…

60’ 1.858 crap, crap, crap
330’ 5.321
1/8 8.202
mph 85.00
990’ 10.637
1/4 12.846
mph 105.10

With my usual short times, I’d have probably got a mid 12.7 and a few more tenths of mph.
Stock turbo, downpipe, catback, injectors, MAF, TB/doghouse, suspension, etc.. The biggest mod is the convertor (2800 non-lockup) that I wouldn’t even have if I didn’t break the stock one at E-town. Aside from that (and the DR’s) I have about $500 into the car.

The stock catback is killing you. For a free "track mod", unbolt the exhaust after the cat and bolt the top part of the catback to the bottom part of the cat. I picked up about 4mph doing this when I had the stock setup. It also spooled like a mofo. Be prepared to up the fuel and turn down the boost a little. My catback was so bad that I gained about 4lbs of boost by doing this.

That was with a gutted cat converter right snorman

No cat...test pipe on the car.

My cat wasn't the problem. I had a THDP and high flow cat, but still had the stock exhaust. It was a major plug in the system. Mine did have 198,000 miles on it though.
