New Time with Headers

[Hammer]

I added some Watson headers over the winter and took the car out for the first time yesterday. I was rewarded with a best of 12.532 @ 112.79. Best time last year here in Boise was 12.959 @ 109.17. That's a gain of .427 in ET and 3.62 MPH.

I think the headers were a good addition. They sound great and the cars pulls really well through the gears. There might be better times available as I noticed the clutch slipping on the way home. I'll get that replaced and try again later.

Good times John.

On the clutch, you may have just overheated it some. Take it out later and load it up and see if you can get it to slip.

Great run John, looks like what you thought it should be.

apples to apples & mods to mods for 2700ft. uncorrected altitude that time is stout, nuf said

Thanks guys. I like the term stout Ryan, that's cool.

Needless to say I'm looking forward to the Gathering and some near sea level runs. I'm thinkin' 12.30's @ 118 will be possible based on what I picked up there last year. Whoopee, come on PNW Gathering.

Tom

Not stock, I have the following add on's:
Watson Headers - No Cats (yet)
Open Lid w/ K&N Filter
Coplon Duct
Marc Haibeck Chip w/ Calibration for the headers
Flowmaster #17115 Cat Back Exhaust
Hurst Short Throw Shifter

The 12.532 run was with a launch at about 3500 RPM's, may have been a little higher too, I don't really watch the RPM's as I am trying for good lights. RT's that day (first of the season) were .121, .113 and .116. I usually run about 28 to 30 lbs of air in the front tires, but didn't let any air out as I wasn't really looking for good lights here (just a T&T). I have the Goodyear GS-D3's and I heat them up with a rolling burnout (no water) and 25-26 lbs of air. The car hooked real well with a 60 ft time of 1.928, the best 60' I've had to date.
Ryan used NHRA correction factors and this run at sea level calced to a 12.12 @ 116.60

That's exactly what I was hoping for Rick. Now you gotta plan on going to PIR at the Gathering so we can get you hooked.

Right at 7k. I've only run three times so haven't got a chance to see what 6500 will do for the times. I ran my best at PIR shifting at 6500. Hope to get a new clutch in it and try again on May 10th.
