Ran a couple 12.7s and a new best mph of 110.5, twice tonight, with my n/a 302. This bests my previous of 110.3 which was run through longtubes and no cats, about 2.5 years ago. Passes were made without the stock fan which showed about 3 hp gain, and the weather was very good. Someday I will get the guts to put the slicks back under it and try to improve on my best ever et.

Thats sweet! 3 HP...Bob Cobsy claimed .05 seconds from the same thing. Did you ditch any extra weight or do anything else? What did the barrometer read tonight?

Good Job Scott!! Your car is still getting faster all the time. The track sounds like it had some bite and the air is awesome right now. Was it crowded?

Nice !!!
I should be ready for the track in the next week or so.
The TKO is installed, and I am building the rear end this week (Moser axles, Eaton Posi, welded axle tubes, etc.....)

Naych-Thanks.

AaronC-Yeah quite a few people and the track was pretty good as well.

TheBrain-Looking forward to seeing you run.

st-3hp is a guess. I didn't actually make any back to back runs. One thing I did notice though is that with the short belt on the crank pulley can be turned with the belt on. So when the fan is on it may slip under load. The baro. was around 30.15. No extra weight savings except for maybe two gallons of gas.

ghetto- The da was about 388 on the first pass, 5:30. And about -481 on the third and final pass at about 7pm.

? You can turn the crank pulley with the belt on? You mean water pump pulley? This reminds me of the the NMRA factory stock rules... I think they mention that the belt must be tight enough to turn all the accesories and not be 'excessively' loose. I wonder how many tenths WD-40 on the belt is worth????

ghetto-Yeah 110.51 @ -481 and 110.57 @ +388. Thats the thing I still can't figure out about those da calculators. I guess all cars don't react the same to changes in weather.

st-Your correct I meant the water pump pulley. The wd-40 mod would probably work pretty good especially since the water pump touches the back of the belt, while the crank and alt. pulleys see the grooved side.

I may just have to try out the WD-40 mod. I just thought up of it when I was typing that last post.


Lets see, 3 inch crank pulley, larger steering pump pulley, bypass smog pump, now WD-40... why don't I just yank the belt and make life easy?
