High mileage dyno numbers
High mileage dyno numbers It seems like I am always seeing threads popping up asking "what is high mileage on a LS1" "How much power does a LS1 loose with age". Well my car has 160,000 miles on it. Runs strong, uses no oil, doesn't knock, or tap. Great gas mileage still. Borla adj catback(wide open plate), P&P TB, and SLP lid, MSD plug wires. I bought the car last summer and basically did a complete tune up on it. Fluids, filters, everything. Just wanted to give a little info/history on the car with the dyno graph. The highest run is with the cutout open and the lower is through the Borla. Saw another thread where somebody was wondering about cutouts so I figured I would open it on a run. Here it is. Tell me what ya think. It was around 90 degrees outside with about 65% humidity.
thats good for a '98. go to the track and seeif the numbers match, I learned the hard way dynos can read way different numbers. Mine went 304 bone stock with 130k miles, then when I put a lid on it it dropped to 290 on the same dyno, track times stayed the same despite warmer, more humid weather. car has 158k miles on it now and I can tell Ive lost some top end when I overlay the most recent dyno graph at 148k miles with when I first bought the car at 130k.
fwiw my car was running 13.6-13.7 @ 104.5 w/ a lid only

Yeah it sucks that Arkansas has no 1/4 mile strip. The closest 1000ft is about 2hrs+ away so its kinda sucky trying to get to the track. Plus its so damn humid and hot right now that I am going to hold off until it cools down. Also wanna get a SLP fan switch so I can keep the fans running without having to run the A/C.
I figured the numbers weren't bad for a 98 since supposedly I got the shittiest intake, heads, and exhaust manifolds. Gonna do some LT's in September. Then LS6 intake, then small cam. Prolly get a crate motor before camming though.
What do most stockish LS1's run on the 1000ft?

I dont know what other stock/mild bolt on LS1 cars run at the 1000' but I know what mine did.
these are my best times from the last two times out to the track, both with only an SLP lid:
1000': 11.546
1/4: 13.740
1000': 11.429
1/4: 13.665
I hesitated to even get it dyno'd that day. I developed some kind of weird almost light bucking surging at low RPM's and it seemed to mess with my WOT feel of the car. However, it was freakin hot and humid outside and I had a passenger. Kinda wish I would've held off to see whats wrong with my car before doing it, but its over now. I am going to scan my car 2mrw for trouble codes. Thinking its my other 02 sensor, but wanna doublecheck. Similiar symptoms to the last one going out.
