Midget,
I want to calculate the torque peak based on header pipe diameter, prior to your selecting possibilities for dyno trial.
For the current car header set & other headers that you have, what I need to get started:
1/ Primary pipe O.D. & wall thickness/gauge
2/ Primary pipe centerline length, approximation OK
For attached collectors:
3/ Collector pipe O.D. & wall thickness/gauge
4/ Collector pipe centerline length, approximation OK
I already have the data from the other pipes from Mini Maven.
BTW: I'm predicting your ultra-long rod will pull the torque peak & bhp peak closer together. . . . . . It will be interesting to see how close the results will match-up. . . . .

Dude – you’re kidding me. You couldn’t have asked me this before I took a shower?
An hour ago, I was out in the garage mocking up the aforementioned headers and an alternate intake manifold.
I feel like a census taker for William the Conqueror. “The Doomsday Book” gets thicker and thicker.
Bloody Normans and their databases . . .
Okay – the dyno adapter – all the bolts line up – the only exception being the one that interferes with the starter. This attaches to the bellhousing of the dyno, so either a shorter cap screw is in order or perhaps a stack of washers. The dyno we’re using has a starter, so I need not clearance the adapter -
This is the header I originally bought. It’s a Peco, pretty much a cheapo street unit, 3-into-1. It fits, it doesn’t leak, and this will be our starting point on Dyno Day -
The intake is a short Maniflow unit I picked up off of E-bay a while back. The flanges are larger than the longer TWM manifold I’ve been using, so if the header flanges clear this, they’ll clear the TWM. Will we use it?
Maybe?
This is the LCB header – “Long Center Branch” - that my buddy Matt Meixner is loaning me. If you will note, it has no collector – it was introduced and reintroduced to the tarmac at Road America on the Carousel and Canada Corner repeatedly and therefore is in need of a weld up. So once I have the primary pipe lengths, the diameter, the gauge, the primary pipe centerline lengths, the impending Pontiff’s hat size, a pony and tickets to see Van Halen, we can make it any length we want. In short, I have no idea what length it originally was, or the diameter. I’ll get you the numbers, and maybe the Pipemax program can ferret out a suggestion.
Capital Maibock tonight - leftovers from my sisters this last weekend.
Meah . . . it's wet.
Stainless - thanks for that. Enjoy your birthday. Your stature is clearly higher then mine if your local brewery creates 5 beers in your honor.
