Well Just got back from the track and am very excited.
I just swapped to solid roller 242/242 @ 112 lsa.
First pass out was 11.62 @ 119 twin to hyd cam best, Then I added 1 degree total adv. from 35 - 36 only above 4800 and added 5% to upper VE from 2500-5600.
That is what netted me a new best of 11.55 @ 120 MPH, also all times are all natural and using 93 pump gas only while still running through SLP shorty headers.
I think next week I am going to uncap the shorties and see what happens,I,m sure it will pick up my ET some more.

 

Mid 11s on 93.
Now, that is, Kewl.

 

87_TA,

Your getting there. Good job. Any idea what the Da was last evening.

I will be frequenting the Keystone strip in the next few weeks. I have a custom single plane intake being fabbed up as we speak for testing purposes.

Can you break down your time slips in more detail 60', 330. etc, I also may be getting a miniram to tests as well. These are from manufactures of the intakes etc, giving them to me for testing purposes. So I would like to see what your getting for reference to when I run them on my car.

This fall will surely be busy, hope to see you down there and good luck/job.

 

Thank you both, that means alot! it seems to be a benchmark I was striving for, well atleast 120 was.
I just need to get more converter to let the ET match the MPH, but I won't do that because the car drives way to nice right now.


Accoring to national weather services for 9pm the DA at pittsburgh raceway park was 2168, ft still not very good but better than its been.

 

Here it goes, I was trying to take a picture of but batteries went dead soo..

60ft..............1.617
330...............4.734
1/8...............7.368
mph..............92.91
1000............9.648
1/4...............11.557
mph.............120.40

 

There we go

 

I got to drive a car with an experimential Yank Converter in it. Instead of the normal 9" they were using a 10, and new vane combintion. So it was loose down low, and really tightened up on top. It was really impressive. You might talk to them about what your doing, and want. The street manners were incredible, pulling away from a light and it just felt like a 2,800 stall Street Fighter, but get into it hard and it was more like a 3,400 Art Carr, with the tighteness of a stocker at 6K rpm. One thing that was really nice is that after the shift when the engine was back down to lower rpm it would flash up a little, and was less prone to the post knock syndrome some converters cause from being too tight.

Then there is the often overlooked PTSExtreme Billet converts. Dunno what they might have on the shelf for you, but the 911 series of their converters are sweethearts too.

FWIW, it seems all the newer good converters are getting really expensive. The lasted Carr, and TCI offerings, just seem lacking. But, converters are really a judgment call on what someone likes or not.

 

Thanks for the great info Grumpy, I've heard great things of Yank and also Vigilante (spelling?) converters .
They are just soo expensive and I just went through a 6 month war with B&M sending me 3 converters ,1 would not lock at all, the other locked 3 times and quit and the 3rd was wrong converter . grrrrrr Then I switched to the streetfighter I have now and is functioning great (knock on wood).
On the lighter side of things I can get the trans in and out in record times LOL.
That will probably be my next move is to get a looser but very streetable converter.
I actually installed my cam 3 degrees advanced to try and help leave harder but did not seem to help. I may try to retard it back later in the year and see how it runs.

Thanks again

 

2168, is not all that bad for our area. Probably won't see much less that than unless you hit a VERY good day. When Corky and I were at Keystone earlier in the year, the DA from my writing on the slips was mid 2000. Maybe this fall we will get some better weather, but I suspect not to see much below 2k.

Your 60' are right where I suspect they would be at low60s.

I am concerned about loosing the 60' times with these other intakes. As I think that is the most fun part of the run. To loose that feeling would be

Maybe the single plane intake will prove itself to be the best hybrid of the SR and MR. Guess we will see.

 

Actually Sat. the DA got down to 1648 but I had to work

I think the single plane will probably work best for you, but your car will make both the MR and the SP look bad in my opinion because of your 3.23 gears. Also remember you can't do that swap and still shift at 5500, both of those intakes will want to rev.
Please keep that in mind during your test.. Are your valve springs up to the task? you will probably want 170+ on the seat.

FWIW: I am shifting my car around 6300,TPIS recomends 6500-6600 but I have installed my cam 3 degrees advanced as mentioned above.

 

87_TA,

I know what your talking about and yes gearing has been considered, however for the SP, the guy doesn't think it will effect the 60' as much. Just got done talking to him again. And the Gears are 3.07s BTW

But our cars have so much friggin torque off the line and all the way through the traps, like he said you can afford to loose some and not miss it. If anything it will make us more consistant, although with some changes we have made, Corky is now hitting 1.48s I have not been back to the track yet to see how mine responds. But I am just missing the 1.4s now. Even if we hit mid 1.5s with the SP, and gain overall up top, IMHO it would be a better tradeoff.

Hell the last time I was at Etown I was pulling the front off the ground and my 60s weren't even that great. LOL. Remember this is not a stripped down car by any means. So that is pretty tough to do, and even tougher with no gears. Jeb, who is making the intake has a 396 with this intake on it and he can't believe the all-round performance we are getting out of these setups. He said 600 fwhp is VERY attainable with just putting the intake on the car. For me its a no brainer, free trial, if it works it stays, if not then back it goes.

1600 DA....man your killin me, I was going to try to go there last week, but Jegs screwed up my order and I got the wrong shoulder straps with my harness. Remember another .1 sec and you'll be getting the red flag for no bar, no harness, etc.

 

And Yes, I know that I have to shift it higher. He said ma power will be at 6000 RPM with that intake, and a shift of 6300 will be perfect.

Also don't let TPIS tell you what you need to do. They are wrong with their products 9/10 times. You don't want to know where corky and I are running our lash at compared to what they recommend.

Sorry for the double post, but the edit function is a feature they take from the probation people, I guess. lol.

 

87_TA,
Great Times. Solid rollers are coming more popular then ever
Aggressive ramps with lots of lift ...Yes theres more to it than that....

Times are in my class also. I run a 6 speed. My high 1.5x to low 1.6x lauches are brutal on my drivetrain....But thats where the ET come's in.

Ski_Down_It==Where are you guys setting your lash hot/cold.
I have been setting mine .013-.015 .

87_TA- Again Great times.

Dennis

 

Thank you bowtye!
I just checked out your site,excellent times. I'll bet that car looks pretty violent with those 60ft times in a 6 speed.

I too would like to know about the lash settings SKI,maybe another thing for me to try..

 

Hey Ski, does your car have a 44 in the rear and does it have stock gears? What kind of 60' can those handle?

 

yep its a 44 with a 307 gear
i talked to some guys from canada who went high 1:30s in the 60s with the dana 44
i personally went 1:48 60 ft

 

That is all right, my best 60' is 1.52thus far. I just made some changes to the suspension and it lookin good to improve it even further.
