Nice!

[Stangman]

Very nice. What is she goin in.

[mn67]

Stangman, it is going in a 1971 Maverick Grabber, pretty light car.

[Stangman]

Wow that little thing is gonna scoot along pretty good. Can’t wait to see the finished  product

[mn67]

It is a tight fit

[WerbyFord]

Cool combo. Was the dyno with open headers or into mufflers?

[mn67]

Werby, good question, I am not positive but I am pretty sure it was into mufflers. I will have to ask.

[WerbyFord]

Werby, good question, I am not positive but I am pretty sure it was into mufflers. I will have to ask.

That was my guess.
See if you can find out diameters, lengths, muffler size/types for the exhaust, it makes a big difference at that power level!

[mbrunson427]

If it was on Jay's dyno, I believe he has a bit of an aside in his book to talk about the exhaust setup of his dyno.

[mn67]

I will look at the book when I get a chance tonight.

I think it was a chicken house full of used tires. 

[cjshaker]

That was a chicken 'coop', not a house. A chicken 'house' would probably raise his taxes and cause the zoning commision to investigate his 'rental' properties

[mn67]

4 Dynomax Two are 2-1/2" in and out, and the other two are 3" in and out.

[WerbyFord]

Thanks that makes sense.

In any case, at least you have plenty of wide open space there in MN. And will need it - even Jay's dyno exhaust was probably costing you 15hp or more the way I figure it. 15hp out of 500 isn't much though, maybe 1mph trap speed.
Thanks for posting, another data set for the Gonkulator!
