Congrats! It'll only get better! This is the fun part...when a new mill runs good and you know there's more left w/ final adjustments!

Hi Mikey, trying to run to calculated numbers from a dyno session/weight is almost impossible as I see it, as you have said those 1.7/8" f/wells will kill off some of that, then you got temps/settings and all the rest of what went on in the dyno room on the day as to what it was like on the day at the track etc. etc. You could change converters and pick up 1>2/10ths and so on, I reckon there's mid>high 9.50's in it with more sorting,...if you use Wallace at dyno no's it'll come up with>
60 Foot E.T. : 1.29
1/8 Mile E.T. : 5.88
1/8 Mile Trap Speed : 115.64
1/4 Mile E.T. : 9.32
1/4 Mile Trap Speed : 144

That I guess is something to aim for but think it would need some parts changing out first.

Nice looking car btw....good luck with it

Thanks Guys, I Bought a set of 2 1/8" stepped Mazzolini Pro part headers and mocked them up but hated haw close they were to everything, Trans,Plugs, Starter ETC. I went back to my old hookers knowing I was gonna hurt the power but I'm going to have a set made this winter, I appreciate the compliments and know I have a little hill to climb to get where I really want to be but iv'e done it before i'll do t again. I will be back at the track in two weeks so I have time to do a little work to get the car to transfer the weight, Hoping to be able to use the transbrake at that point. I'll update again!

So if I make it we`ll go at it again for a beer or three.............

Now this sounds like some FUN.

You know how we roll at our camp, win or lose that race I win

I would think those small headers will hold it back, although 2-1/4 headers seems big for a 470. The hedman huslers make good power or maybe TTI 2" to 2-1/8" step headers as another option. Custom would probably be the best for power and starter clearance etc.

Yep..

And I'm NOT Crazy..



Chris..

I`ll see how it goes and let ya know just not sure on those bitty 28`s in the 1/4 but we'll see...........

.... schedule in an extra day for MaTS Mike and maybe you can take the long way to Vegas through Kingman AZ and have Greg conjur up a set! Headers in a day! Hopefully I line up with you in eliminations before you get the rust knocked off!

Sound Good to me, going to tweak a couple things for that race on the 17th. Lookin forward to seeing you there!

Don't forget the go-pro Mikey.............

On a 715hp motor I had on the dyno, swapping from my dyno headers(2-2 1/8 x 4) to a set of 1 7/8 x 3.5 Hooker fenderwells cost about 40hp peak to peak, and 54hp at 6500rpm.

With the 1 7/8 headers installed in the car(678hp), at 3450- 3500lbs race weight, it went a best of 9.68 @ 137 in good air.......1.28 60'.

I've been talking with a guy recently who is working through a new combo.
4+ mph difference between two different converters, both custom built for the application, with no other changes to the car.
In his combo that shows up as a 65hp difference.

I'll have it on board this time, me & gauges have never been a friend.

Going to put the Proparts headers on it and work on suspension.h ow far into the collector should the sensor be?

I put mine as far up as i could go, do you run collectors ?

What sensor??? Is it a wideband deal? And man I hope you run collectors Keep in mind this is an average of the four cylinders on that bank, so don't forget to look at plugs too. As far as placement not to close tot he end but not to far up as to be influenced by a single tube either

Good info fast68....once you understand how Wallace seems to be softwared as it were, you find that an S/SS car that leaves at 6k+ just doesn't compute to the numbers spat out as shown below for that weight/hp combo, so>

3500/678hp>
60 Foot E.T. : 1.39
1/8 Mile E.T. : 6.32
1/8 Mile Trap Speed : 107.48
1/4 Mile E.T. : 10.02
1/4 Mile Trap Speed : 134

IF this is an S/SS car or a hard leaver I can understand the lower 60 and hence the ET drop to 9.68 but what about the 137mph, at the same 678hp, shortening distance and time doesn't allow you to build more speed....somewhat confusing? ..One of our legal stockers used to run 10.1's@128

or you get this>

3500/747hp>
60 Foot E.T. : 1.35
1/8 Mile E.T. : 6.15
1/8 Mile Trap Speed : 110.52
1/4 Mile E.T. : 9.75
1/4 Mile Trap Speed : 137

It wasn't a class car, just a regular bracket car.

The moroso chart shows 682hp for 137mph, with an ET of 9.77.
His car left better than a typical car running those numbers, which is why the overall ET was better than the speed would indicate.
The moroso chart shows 138.5mph to run 9.68 but the motor didnt have enough top end pull for that.
Also, keep in mind that's a good air day.
Typical speeds were more in the 135 range.

According to who you talk to and being a single sensor, 8-10 inches past the merge in the collector and PLEASE add an extension like Al suggested instead of just headers by themselves...............

OK, back at it at Famoso. Changed the headers to 2 1/8th stepped from the 1 7/8". Changed timing from 34 to 38. First run at noon and went 9.72 @ 139 and spun on the TB, only change from there was went to foot brake. Went 9.64. @ 139 and 60 foot cam back a little. I'm not understanding the coil overs very much and its not transferring the weight. Anyway the air is around 2600 right now. It still has more in it just need to keep working on it. Only the 5th run on this combo.
