I see your Father won first round

Lane Driver Car No. Class Dial In RT 60 FT 330 FT 660 FT 660 MPH 1000 FT ET MPH

I spend sometime redoing my simulation. What was the weather like? I had to pull a good amount of HP to somewhat match his run.

60 Foot ET = 1.6786
330 Foot ET = 4.7139
1/8 Mile ET = 6.7322
1/8 Mile MPH = 123.4014
1000 Foot ET = 8.4490
1/4 Mile ET = 9.8945
1/4 Mile MPH = 156.9030

The air was good I think I recorded a corrected alt of 1250ish ft this morning.

Here’s the timeslip I gave you the info on.

[Stan Weiss]

Matt,
Thanks you very much for all of that information. I now see why I am having a problem, and having to pull so much HP. I wrote this code over 11 years ago while trying to help someone out, and it only uses a single timer.

No worries , your calculations have been impressive.

Matt, 1st off THANK YOU for making a swing with cam selection! Ya Gota make moves to move forward. That you did, that’s what moves the Pontiac community forward.
2cnd I have checked out you and your dads beautiful cars on numerous occasions,they are breath taking.
You guys are always in the motorhome so I really haven’t talked to y’all much

My 2cents on your original question, have you tried merge collectors?
I’ve always heard keep making the choke point smaller and smaller until it falls off then go back to the merge collector that made the most power.


I’m in that horsepower range but our motors are way different considering I run a 18 degree big chief head.
But for what it’s worth I have a 2 3/8 primary tube and a 5” merge collector that chokes down to 4”.

Feel free to knock on the door any time. I may have you mixed up but did I talk to yall at bowling green a couple years ago? I’ve been looking at collectors but trying to gather more data before buying. I believe I’m going to build another set with smaller tubes & merge collectors . I got a quote from Burns yesterday but they forgot to title the email sit down before viewing.

I bought some Schoenfeld merge collectors for my 2" Mad Dog 3 piece headers. 3 1/2" collectors so I was going to buy some 3" merge collectors (500$!!) Called their tech and they asked what HP of a engine I was putting them on and I told them 700ish. The recommended a 2 3/4 neck down collector.
I was concerned about it being too small and they assured me 2 3/4" was the number. They ran them on 900 HP Sprint car engines so I bought what they recommended.
Just got them all back from Caps Coatings, NICE !
Called their tech and they gave me the rundown on breaking them in. They want extra fans on the headers when you fire them up. And told me if there is a fingerprint on them it will get baked in. Clean them with alcohol first.
I am worried about installing them without scratching them all up. So they said to wrap them in blue painters tape first.
Its going to be one big pain but should be worth it.
