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:cheers:

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.

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

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.

Good runs. Where are you shifting @ with the headers?

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.

Hammer,

Put a scantool on the car during a run. See if there's any KR going on?

[Polo-1]

If you still do not have port work, I think you will do better @ 64-6500 rpm.

[cuisinartvette]

3mph, nice addition. Man I hope I canget some LTs this next year sometime. Just dying to do porting.

[bradslt5]

[Peaven]

Definately a good testimonial for what headers do for this engine...nice times John.:cheers:

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

John, Thanks for the reply!

Okay, not box stock.....but damn man you didn't mention any porting of the top end & checking the cams' timming & adjusting if need be....just, well, just Damn that car is quick!:thumbsup:

Stout motor ya got there!:worship:

No problem on the reply Tom. No porting, and probably won't. I'm pretty happy with the way the car runs now and never have been one that longs for more and more.

I bracket raced a '70 Camaro for 8 years and watched everyone around me go faster and faster and spend more and more money. All it got them was a car that would eat up their bank accounts. The funny thing was I whipped their *** everytime I pulled to the line with them. They'd come over and we'd talk about how much faster they were and I'd put the money (from the wins) in the bank and they'd just spend more to go even faster and break more stuff.

[tomtom72]

Well all I can say is that your skill as a driver shows, and the car ain't too shabby either! :thumbsup:

Oh, and I agree 100% with what you wrote in the post above! Almost any sports car is a money pit, how big of a pit just depends upon how fast & quick ya wanna go! I remember this line from somewhere: "Speed secrets, besides military secrets, are the most fleeting secrets in all the world!".....I think it was in a car mag...I think?

:cheers:

I agree about trying to go tooo far power wise , with one exception the porting of the inj and plenum . its a no brainer along with the headers and really completes the car. going any farther gets costly .. i can hardly wait to see what headers do on the callaway . very nice 60ft on street tires by the by . i'll bet you drive the youngsters nuts having their modded cars being slower than you ,these cars still hold their own after all these years.:cheers:

Nice times John. Glad too see that you are out enjoying the car !

[flyin ryan]

John, Thanks for the reply!

Okay, not box stock.....but damn

Stout motor ya got there!:worship:i'm with ya, considering he hasn't opened up the lump at all...can't say he isn't getting the most out of it. i'm impressed & believe me that dosen't come easily.

[Hammer]

Thanks for all the compliments guys. I'm pretty happy with the results.

I talked with Marc the other day and as far as the clutch goes for our cars that are under 500 HP, he has used the Duralast Clutch from Autozone, Part No. NU0084, $258. He has had good luck with it and that's good enough for me.

[bradslt5]

just a thought . corey put a ceramic disc in when we did the fidanza and boy does she grab well . even after 50+ runs at the strip .

[Nick]

Nice results, John! Anxious to see you and the car this Summer! :mrgreen:
